Clonidine
Ence of clonidine, De Kock et al.14 reported that the toxicity of bupivacaine is not augmented by clonidine and Yokoyama et ql.8 showed neither proconvulsant nor anticonvulsant effects of clonidine on lidocaine-induced convulsions. Thus, the possible potential toxicity of this drug interaction also needs to be clarified. In conclusion, this study has documented a pharmacokinetic drug interaction between clonidine and bupivacaine suggesting an inhibition of bupivacaine metabolism. Further in vitro experimental studies will be required to determine the precise mechanisms involved.

The misuse of Alcohol and Drugs is one of the most significant threats to public health in this country at this time. To tackle this rising epidemic there is an urgent need to implement national policy, including the need to ensure effective treatment services are available for those affected by alcohol and other drugs of misuse. This research specifically assesses the need for detoxification services in the Cork and Kerry region. The excellence of the research and the rigour with which it was conducted are a tribute to the Principal Researcher, Dr. Mai Mannix, Specialist Registrar in Public Health Medicine. It will prove extremely valuable in informing the planning and delivery of services in the region and in so doing will help to curb the epidemic and improve the health and quality of life of the people of Cork and Kerry.

Clonidine 20 mg
After institutional approval and informed parental consent, we enrolled 58 pediatric patients aged 0.5-6 yr in a prospective, randomized, double-blind, placebo-controlled study. Patients were scheduled for unilateral ambulatory hernia repair and were randomized to one of five treatment groups for caudal block: 0.75 ml kg 0.25% bupivacaine B group ; , bupivacaine plus 3.75 pg kg epinephrine BE group ; , bupivacaine plus 1 pg kg clonidine BCl and BC2 groups, respectively ; . Saline 0.75 ml kg was used as placebo I' group ; . Drugs were prepared by an anesthesiologist not otherwise involved in the study. One surgeon performed all of the hernia operations, thereby standardizing the technique and surgical patient management. All children received rectal midazolam 0.75 mg kg as premeditation. Before caudal block, IV access was established under halothane anesthesia administered via face or laryngeal mask, and a glucose saline solution was infused at the rate of 10 ml * kg-i * h-l. Thereafter, caudal block was performed with a 22gauge Quincke needle under aseptic conditions with the child in a left lateral position and immediately turned supine after injection of the drug. Anesthesia was maintained with 0.5%-l% halothane and 70% nitrous oxide in oxygen using standard monitoring. Mean arterial pressure MAP ; and heart rate HR ; values were obtained 5 min before the induction of anesthesia baseline value; 30-45 min after rectal sedation ; and every 5 min thereafter during the operation. Patients breathed spontaneously with manual assistance throughout the anesthetic and the surgical procedure. At the beginning of skin closure, anesthetics were discontinued. Once patients were sufficiently awake, they were brought to the recovery room, breathing room air. After arrival, MAP, HR, and percutaneous oxygen saturation SpoJ were documented every 15 min until 6 h after injection. An intra- or.

ORTHOSTATIC HYPOTENSION fl om vwr ing adaptation to weightlessness. Postflight orthostatic intolerance is present to some extent in virtually all returning astronauts. The degree of orthostatic intolerance and the loss of exercise capacity following space flight are also significantly greater than would be predicted from the total blood volume loss. It has also been shown that blood volume loss during bed rest can be prevented by the administration of fludrocortisone or corrected by intravenous fluid administration without completely restoring normal hemodynamics.14 Similarly, exercise in the supine position during bed rest does not prevent the development of orthostatic intolerance, whereas spending a few hours per day in the standing or sitting position is an effective countermeasure.14 The regulatory adaptations that are responsible for the disproportionately large effect of the hypovolemia remain to be defined. On the other hand, there seems to be little doubt that the fluid shift is the primary stimulus to the changes that develop during bed rest. This point has clinical relevance and provides a rationale for the reemphasis of the 40-year-old armchair approach to the treatment of acute cardiovascular disorders, including myocardial infarction, as described by Levine and Lown.45 Therapeutic Aspects The large variety of therapeutic agents that have been used to treat orthostatic intolerance in general and the hyperadrenergic variety in particular is a certain indicator that our understanding of the pathophysiology is incomplete. Management often includes a combination of pharmacological agents designed to expand blood volume and to enhance compensatory reflex adjustments. A high salt diet is often prescribed as an initial step.46 An appropriate second step is fludrocortisone therapy, which is effective in many different forms of orthostatic hypotension. The mechanism of action is a combination of salt and water retention and increased vascular responsiveness to norepinephrine and angiotensin, 47 an effect also produced by indomethacin.48 3-Adreneregic blocking agents and a dopaminergic antagonist have been used in hyperadrenergic orthostatic hypotension with the rationale of opposing active neurogenic vasodilatation, but there is little evidence that this mode of therapy is effective. Gaffney et al." treated eight patients with dysautonomia including 5 with MVP ; with clonidine. All had symptomatic orthostatic intolerance. Treatment with clonidine, up to 0.4 mg day for at least 1 month, reduced standing plasma norepinephrine levels and total peripheral resistance. A smaller postural decrease in cardiac output occurred after treatment, which also increased plasma volume by 12%. The objective improvement was paralleled by marked relief of symptoms. The mode of action is not entirely clear, but it seems likely that clonidine interrupted the link between chronic vasoconstriction, hypovolemia, and orthostatic intolerance. Nonpharmacological treatment regimens have also been employed. Pressure garments to prevent excessive peripheral pooling have generally been of limited and hydrochlorothiazide.

Martina Prelog, Georg Wick, and Roswitha Sgonc Institute of Pathophysiology, University of Medicine, Innsbruck, Austria Objective: In a previous ex vivo study we have identified an 2 I ; -mRNA variant, that is increased during early, acute scleroderma-like disease in University of California at Davis line 200 UCD-200 ; chickens. This 2 I ; -mRNA transcript is represented by a 115bp band in RNase protection assays RPA ; , whereas the expected band is 180bp in size. The aim of the present study was to investigate the influence of cytokines on the expression of these two 2 I ; -mRNA variants. Methods: Chicken embryonic fibroblasts CEF ; of UCD-200 and normal White Leghorns NWL ; were grown in monolayer or 3-dimensional collagen gels. Procollagen-mRNA expression was analyzed by RPA, proliferation by 3H-thymidine incorporation. TGF-1 and TGF-2 in culture supernatants was measured by ELISA. Results: In collagen gels, UCD-200-CEF expressed 7.2 times more of the smaller profibrotic 2 I ; -mRNA variant than NWLCEF, the latter lacking the 115bp band in - the less physiologic monolayers completely. TGF-1 stimulated the proliferation of UCD-200-CEF, but not NWL-CEF. The 115 180bp ratio was increased by TGF-1 in both, NWL- and UCD-200-CEF. TGF-2 and TGF-3 reduced the expression of the profibrotic 2 I ; mRNA in UCD-200-CEF to the same levels seen in healthy control NWL-CEF. Moreover, TGF-2 also reduced the 180bp transcript in UCD-200 and NWL-CEF, whereas TGF-3 reduced the 180bp band only in NWL, but not in UCD-200-CEF. Interestingly, analysis of cell culture supernatants revealed that NWL-CEF produced 4.1 times more TGF-2 than UCD-CEF. Conclusions: We could show that TGF-2 reduces the expression of a profibrotic 2 I ; -mRNA variant in UCD-200CEF. The constitutive overproduction of this 2 I ; -mRNA variant and diminished TGF-2 synthesis found in untreated UCD-200CEF suggest that TGF-2 is an antifibrotic cytokine and might be a key player during fibrosis onset. These results also may shed some light on the contradictory reports on TGF-2 in human SSc. Supported by the Austrian Science Fund project no. 14466.

NADE is the one and only disability professional organization that exists for all disability professionals! If you aren't a member, you will find that gaining access to those power brokers on the Hill and in the offices of SSA in Baltimore could potentially be a greater challenge. The power and the prestige which you enjoy by claiming ownership of that coveted membership card is worth so much more than .00 per year! I daresay that my membership in NADE is priceless. ; MOTIVATION I can tell you this much! Since I joined NADE four years ago, in December 1998, I have become a much more motivated employee. I have become much more motivated to learn about the changes which are taking place in the Social Security Disability program, to strengthen my knowledge regarding medical and vocational issues, and I have become much more motivated to assume leadership roles on the local, regional and national levels. These experiences have all served to contribute to greater self-esteem, to a sense of pride and accomplishment and to my growth as a professional and as a human being. Now, I much more look forward to coming to work every day and much better able and willing to face the many challenges that are waiting for me at the office.
One of the innovations of Lurianic Kabbalah was the creation of a variety of rituals which took place late at night. Joseph Karo is credited with the creation of the all-night study session on the eve of Shavuot, called Tikkun Leil Shavuot. The Ari himself emphasized the importance of prayer and meditation late at night called Tikkun Chatzot or Tikkun Rachel ; and early in the morning called Tikkun Leah ; . These times connected the individual with the daily creations of light and darkness. It also was an ideal time according to the Zohar ; to mourn the banishment of the Shechinah from Jerusalem. It also connected the individual with King David, who was said to have created the Psalms at midnight. The powerful image that the gates of Heaven are most available for prayer late at night was thus concretized in Tzfat in the late 16th century. Ironically, it didn't catch on in Jerusalem at the same time even though Jerusalem mystics were certainly aware of the Zohar's emphasis on midnight and all-night vigils. Jerusalem's mystics focused on pre-dawn rituals instead. Elliott Horowitz provides us with a fascinating thesis about the creation and development of late-night and all-night rituals as opposed to early morning rituals in 17th-18th century Jewish mystical circles. He notes that coffee arrived in Tzfat in 1528, and the first coffee house appeared in Tzfat in 1580. None came to Jerusalem. The use of coffee as a stimulant might have encouraged the mystics of Tzfat to focus more on all-night and late-night rituals because they couldn't sleep anyway. Karo's Tikkun Leil Shavuot appeared two or three years after the introduction of coffee to Tzfat. Horowitz quotes the following description of Tzfat in 1587: Abraham haLevi Beruchim ; would rise at midnight and walk through all the streets, raising his voice and shouting bitterly, "Arise in honor of the Lord.for the Shechinah is in exile and our Temple has been burnt and benicar.

Immunosuppression post kidney transplant. Updated kidney transplant order sets in WizOrder as of Apr 2006 thanks to Deonna Moore and Christie Buchanan ; . You will have a choice of 4 different immunosuppressive protocols: 1. Steroid Avoidance Thymo 2. Steroids Thymo 3. Steroids Simulect 4. Calcineurin inhibitor avoidance Current default protocol is Steroid Avoidance Thymo. 1. In general, low immunologic risk 1st transplant, unsensitized, living donors ; and intermediate immunologic risk African-Americans, poorly matched deceased donor transplants, ECD kidneys at risk for DGF ; patients will start on steroid avoidance protocol. 2. High immunologic risk patients re-transplants, high PRA ; generally get steroids thymo. 3. Low immunologic risk patients but who otherwise need steroids e.g. lupus patient who comes in already steroid dependent ; generally get steroids Simulect. 4. There will be a small number of patients in whom we want to avoid calcineurin inhibitors de novo HUS pts; patients with pre-exisiting malignancy ; and they would get CNI avoidance protocol thymo, steroids, MMF, and rapa ; . 5. There will be a few patients who should get steroid avoidance and Simulect e.g. 2 haplotype match LRD ; - there is no specific protocol for this, just use steroid avoidance and substitute Simulect for thymo. 6. There may be some high risk patients in whom you want to avoid thymo, i.e. retransplant who has had thymo previously and you want to avoid risk of serum sickness; we use Campath 30 mg IV intra-op in this situation-again, no separate protocol in Wiz for this, just order Campath intraop and don't order thymo intra-op or post-op, everything else is the same.

Formulary Preferred Tier 1 ; : These drugs have a proven record of safety and effectiveness and offer the best value for our members. They require the lowest copayment, making them your most cost-effective option for treatment. Most generic drugs and some brand name drugs are Formulary Preferred Tier 1 ; . Formulary Options Tier 2 ; : These drugs also have a proven record of safety and effectiveness. Since a more cost-effective therapy or a generic alternative is usually available, most BCN drug riders require a higher copayment for drugs in Tier 2. Nonformulary Tier 3 ; : Nonformulary drugs are not on our list of approved drugs. These drugs may not have a proven record for safety or their clinical value may not be as high as drugs in the Tier 1 or Tier 2 categories. Depending on your drug rider, you may pay a higher copayment or the entire cost of these drugs.
If the ALF is licensed for assisted living, has a contract with DMAS, and the care need is authorized by an authorized assessor, then the ALF may receive payment as indicated. However, a change in level of care is only authorized by completing the UAI and a new DMAS-96. An assessment for a change in level of care is not conducted for temporary changes expected to last less than 30 days. REIMBURSEMENTS TO THE ASSESSOR FOR INITIAL ASSESSMENTS AND CHANGES IN LEVEL OF CARE Reimbursement for initial assessments and changes in level of care will be based upon the submitted admission package information similar to the current NHPAS process. In order to receive reimbursement for assessments, the authorized assessor must have a signed DMAS provider agreement and provider number. The provider number must be noted on the DMAS-96 to indicate to whom the payment should be made. See Chapter VI for instructions on the reimbursement process. TIME LIMITATION ON ASSESSMENTS An authorized assessor's approval decision regarding an individual's appropriateness for ALF placement is valid for twelve months or until an individual's functional or medical status changes, and the change indicates the individual may no longer meet the authorized level of care criteria. If the current ALF residents have been assessed with the UAI by any public human services agency, and the assessment is less than 12 months old, it is not necessary to complete a new UAI and metformin!
As clonidine has frequently been added to local anaesthetics at low doses, the effect of 10 mM clonidine on action potentials was investigated. A higher concentration of clonidine related to the IC50 for Na currents 700 mM ; was selected for a better comparison with other drugs e.g. local anaesthetics or opioids, which have also been investigated at concentrations related to the IC50 for Na currents ; .13 15 16 Current clamp experiments were performed in intact neurones in the spinal cord slice using external solution in the bath and pipettes filled with high K-1-solution. Single action potentials were elicited using 1-ms depolarizing current pulses Fig. 1 and Table 1 ; . A concentration of 10 mM clonidine had little effect on the shape of a single action potential in all three cell types. In TFNs, the firing threshold was lowered significantly. A higher concentration of clonidine 700 mM ; had significant.

Health problems and for whom maintaining employment is important for future economic security and ongoing access to health insurance. Study Design: Using 6 waves of the Health and Retirement Survey 1992-2002 ; , a longitudinal study of a nationally representative sample, we created a panel data set using data from each wave 1-5 ; to predict outcomes in the subsequent wave 2-6 ; . We used Marginal Structural Modeling techniques to simulate randomization and to estimate the impact of health insurance coverage and adequate access to prescribed drugs on mobility and employment outcomes. Population Studied: A nationally representative sample of individuals age 51-61 when they enter the study, working full time in each each base wave 1-5 ; and who remained under age 65 in the follow-up wave 2-6 ; . The age restrictions were applied to remove people as they became eligible for Medicare coverage and would be likely to retire. Principle Findings: Controlling for a range of demographic and health status variables, the odds of maintaining mobility over a two year period were 21% higher p 0.01 ; for those with health insurance at baseline compared to those without and 74% higher p 0.01 ; for those with adequate access to prescribed medications compared to those without. The odds of maintaining full time employment over a two year time period were 38% higher p 0.01 ; for those with health insurance. The results of the marginal effects analysis show that even after randomization the effects remain significant. Conclusion: Among working people approaching retirement age, health insurance and adequate access to prescribed drugs have protective effects against declines in mobility, and health insurance also supports sustained full time employment. Implications for Policy, Practice or Delivery: Among working people approaching retirement age, health insurance and adequate access to prescribed drugs have protective effects against declines in mobility, and health insurance also supports sustained full time employment. These findings are consistent with the intent of the Ticket to Work demonstration and support initiatives to extend insurance and prescription drug coverage to the "pre-Medicare" population.

The most commonly used medications for Attention Deficit Hyperactivity Disorder ADHD ; are central nervous system stimulants which contain the chemical compounds methylphenidate e.g. Ritalin, Concerta, Metadate and Methylin ; , dextroamphetamine Dexedrine and Dextrostat ; and mixed amphetamine salts Adderall ; . Stimulants have proved effective for ADHD symptoms in children with and without TS. Common side effects of stimulants include appetite suppression and difficulty falling asleep. One of the greatest drawbacks of stimulant medications is their short duration of action. To have maximum benefit, children with ADHD may have to take medication multiple times each day including at school. To address this drawback the pharmaceutical industry has developed new longer acting preparations to extend the duration of benefit thus making stimulants more useful for people over the course of a day. In the late 1970's and 1980's there were numerous published reports that children taking stimulants developed new onset tics or experienced worsening tics. One confounding factor regarding stimulants "causing" new or worsening tics is the fact that ADHD symptoms often emerge before the development of tics. So if stimulants are begun for ADHD and then tics appear, it is difficult to know whether the tics are "caused" by the stimulant, or whether the onset of tics would have occurred anyway as part of the natural course of the tic disorder. Whether stimulants actually cause tic worsening can be determined in a research study by comparing the rates of tic worsening in subjects on medication vs. placebo. In such studies, tic worsening has not occurred more commonly in those on stimulant medication compared to placebo. Interestingly, the Tourette Syndrome Study Group's study comparing methylphenidate to clonidine and placebo showed similar rates of tic worsening approximately 20-25% ; in each group. The lack of a difference between methylphenidate and placebo suggests there is no risk for tic worsening that can be specifically attributed to taking the stimulant methylphenidate. It is important for the clinician, parents and the child to pay attention to how frequently tics worsen after starting medication treatment. All should be aware that tic worsening is something that might occur during any treatment with any medication, even placebo, and to be careful about 8 attributing such worsening to having begun to take a medication. Although it appears that stimulants can be used safely in people with tics and ADHD, the product labeling of methyphenidate and amphetamine products discourages using stimulants in people with tics or people with a family history of tics. Although scientific studies do not necessarily support this concern, it is highly unlikely that the labeling will change. As you can imagine it is difficult for a pharmaceutical company to remove warnings from their labeling as it may make them more vulnerable to lawsuits. For children with tics and ADHD whose clinician has recommended a stimulant, it is important to know that the evidence base for safety and the product information for stimulants don't completely match up. Lastly, recent media reports and U.S. Food and Drug Administration hearings have alerted all to the risk of stimulants in children with known heart defects and also to the worsening of symptoms of other psychiatric disorders. It is important before beginning to take stimulants that the prescribing clinician be aware of the patient's personal and family history of cardiac problems.

219 increases the tone of upper airway muscles, and hypoxia is an important stimulus [22]. Clonidine may have attenuated this reflex at the peripheral chemoreceptors. Therefore, it is likely that clonidine can cause oxygen desaturations through both its sedative effect and via an effect on the peripheral chemoreflex pathway. In conclusion, we have demonstrated that clonidine reduced the initial increase and subsequent reduction in ventilation during sustained hypoxia. However, the absolute level of ventilation at the end of the hypoxic period was unchanged. Blunting of this protective mechanism suggests that the use of clonidine in patients requires respiratory monitoring, especially when used with other agents which depress ventilation!

Bruun RD, Budman CL: J Clin Psychiatry 1996; 57: 29-31 Abstract: Background: An open-label trial was performed to assess the efficacy and safety of risperidone, a benzisoxazole derivative with potent D2 and 5-HT2 antagonism, for treatment of Tourette's syndrome. Method: Thirty-eight patients with Tourette's syndrome volunteered to take risperidone for treatment of their tics. All patients had failed to respond adequately to conventional treatments with neuroleptics such as haloperidol and or with the 2-adrenergic agonist clonidine ; or had suffered from intolerable side effects from such treatments. Patients were rated for tic severity by the Yale Global Tic Severity Scale YGTSS ; before treatment and after 1 month of treatment with risperidone. Patients were monitored carefully for side effects and clinical response. Results: Of the 38 patients, 8 discontinued risperidone treatment before the end of the trial because of intolerable side effects. At the end of the 4-week trial, 22 patients 58% ; were improved, 7 patients 18% ; had no appreciable change in their symptoms, and 1 patient 3% ; had a documented worsening of tics. Doses of risperidone at the end of the trial ranged from 0.5 mg to 9 mg day mean 2.7 mg day ; . Conclusion: This open clinical trial suggests that risperidone may be a promising alternative to conventional medications used for treating the symptoms of Tourette's syndrome and buy avalide.
For crisis prevention the opioid receptor antagonist naloxone is effective in treating respiratory depression and coma in patients with an opiate overdose, but the extended use of opioid antagonists can lead to a supersensitivity and therefore to an increased risk of overdose after leaving treatment. The opiate agonist methadone, buprenorphine, including the combination with naloxone, and clonidine and lofexidine are effective agents for detoxification treatment of opiate dependence. Methadone, the most commonly used detoxification agent in Europe, is the most effective opiate agonist for detoxification treatment, leading to reduced withdrawal symptoms and increased completion rates compared to placebo or other opiate agonists. Buprenorphine, also commonly used in Europe for detoxification treatment of opiate dependence, provided a nearly equal efficacy as methadone. Also the combination of buprenorphine and naloxone is effective and safe for the detoxification of opioid dependents. Clonidine and lofexidine are commonly used to manage the acute phase of opioid withdrawal. They are especially effective for patients, who prefer non-opioid treatment for detoxification, but lead to more side effects and higher drop-out rates than methadone or buprenorphine. In Europe methadone is the most used agent for maintenance treatment so far and the most effective opioid agonist, but the effectiveness of methadone in maintenance treatment is strongly dose-related. Higher doses are associated with better treatment retention rates and lower rates of illicit opioid use. Besides a nearly equal efficacy of methadone with regard to reduction of illicit opioid use and treatment retention, buprenorphine maintenance treatment provides a better safety profile at high doses, a lower abuse potential, the possibility of a less-than-daily administration compared to methadone. The efficacy of buprenorphine in combination with naloxone seems to be comparable to buprenorphine alone. The prescription of diamorphine heroin ; is especially effective for people with opioid dependence who continue intravenous heroin use while on methadone maintenance or who are not enrolled in treatment. Furthermore, other substances for maintenance treatment, such as codeine and slowrelease morphines, could be valuable additions to the current treatment repertoire in Europe. The maintenance with the opioid antagonist naltrexone for relapse prevention of opiate dependence seems not to be effective as a stand-alone treatment and should therefore be part of a broader treatment programme. No medication has been found yet that can be considered a standard for treating stimulant or cannabis dependence effectively, although a number of different medications have been tried. Much hope is being placed in the development of the cocaine vaccine. 3. Generally speaking, psychosocial interventions are efficacious to reduce drug use, maintain abstinence and improve treatment retention. Psychosocial interventions are especially useful where no pharmacotherapy is available, e.g. for the treatment of cocaine and amphetamine dependence. For the treatment of heroin dependence psychosocial interventions do enhance treatment outcomes in combination with maintenance therapy.

Studies showed that the use of pre-incisional dextromethorphan 40-120 mg IM in laparoscopic cholecystectomy and upper-abdominal surgery provides pre-emptive analgesia. Alpha-2-Agonists: Clonidine and Dexmedetomidine Clonidine is a selective alpha 2-receptor agonist that provides sedation, analgesia and hemodynamic stability and reduces requirement for inhalation agents and postoperative analgesia. Dr. Chung briefly stated the results of several studies. Intrathecal administration of clonidine 15 mcg in addition to ropivicaine produces adequate and short-lasting anesthesia for knee arthroscopy. Also, when used as an adjunct to peripheral nerve blocks, it can extend the block by several hours. Intra-articular administration of clonidine 150 mcg alone for knee arthroscopy improved postoperative analgesia by six hours compared to just local anesthetics. Intravenous regional anesthesia combining lidocaine and clonidine prolongs analgesia as well. In short, there are numerous studies that demonstrate that clonidine alone has analgesic effect after systemic, peripheral and intrathecal administration; however, all relevant studies demonstrate that the major role of clonidine is as an adjuvant to local anesthesia and opioids. Dr. Chung quickly stated the results of the use of intravenous dexmedetomidine 0.2 or 0.4 ug kg in the postanesthesia care unit for postoperative pain after laparoscopic tubal ligation. The results revealed a reduction in pain and opioid analgesia requirements, however, at the expense of sedation and bradycardia.

Purpose: To evaluate the effect of adding clonidine to ropivacaine, for axillary brachial plexus blockade, on the onset and duration of sensory and motor block and duration of analgesia. Methods: In a prospective randomised double blind placebo controlled study axillary brachial plexus blockade was performed in 50 patients using 40 ml ropivacaine 0.75 %. Group A ; had 150 g clonidine and Group B ; 1 ml normal saline added to the local anesthetic. Sensory function was tested using pinprick sharp sensation, blunt sensation or no sensation ; and temperature with an ice cube compared with the opposite arm, cold not cold ; . Motor function was assessed using a modified Bromage scale. Postoperative analgesia was standardised. Onset and duration of sensory and motor blockade, duration of analgesia, postoperative pain score, and analgesic requirement were compared. Results: The clonidine patients showed an increase in duration of sensory loss from 489 min to 628 min with a mean difference of 138 min 95% confidence interval of 90 to 187 min ; , motor blockade from 552 min to 721 min with a mean difference of 170 min 95% confidence interval of 117 to 222 min ; , and analgesia from 587 min to 828 min with mean difference of 241 min 95% confidence interval of 188 to 294 min ; . There was no difference in onset time. No side effects were noted. Conclusion: The addition of 150 g of clonidine to ropivacaine, for brachial plexus blockade, prolongs motor and sensory block and analgesia, without an increased incidence of side effects. Objectif : valuer l'effet d'un ajout de clonidine la ropivacane, pour le blocage du plexus brachial axillaire, sur le dlai d'installation et la dure du bloc sensitif et moteur et sur la dure de l'analgsie. Mthode : Il s'agit d'une tude prospective, randomise et double insu contre placebo. Un blocage du plexus brachial axillaire a t ralis chez 50 patients en utilisant 40 ml de ropivacane 0, 75 %. On a ajout l'anesthsique local, 150 g de clonidine pour les patients du groupe A et 1 ml de solution sale pour ceux du groupe B. La fonction sensitive a t teste par piqre d'pingle sensation vive, lgre sensation ou insensibilit ; et la temprature par un cube de glace pos en alternance sur les deux bras froid, non froid ; . La fonction motrice a t value avec une chelle de Bromage modifie. L'analgsie postopratoire a t normalise. On a compar le dlai d'installation et la dure du blocage sensitif et moteur, la dure de l'analgsie, le score de douleur postopratoire et les besoins analgsiques. Rsultats : Chez les patients qui ont reu de la clonidine, on a not une perte sensitive de plus longue dure, de 489 min 628 min avec une diffrence moyenne de 138 min intervalle de confiance de 95 %, de 187 min ; , un blocage moteur plus long de 552 min 721 min avec une diffrence moyenne de 170 min IC de 95 %, 117 222 min ; et une meilleure analgsie de 587 min 828 min avec une diffrence moyenne de 241 min IC de 95 %, 188 294 min ; . Il n'y a pas eu de diffrence de dlai d'installation. Aucun effet secondaire n'a t enregistr. Conclusion : L'ajout de 150 g de clonidine la ropivacane, pour un blocage du plexus brachial, prolonge le bloc moteur et sensitif et l'analgsie sans augmenter les effets secondaires.
