fa تاثیر دگزامتازون در پیشگیری از لرز بعد از اعمال جراحی کوله سیستکتومی تحت بی‌هوشی عمومی آناتومی آناتومی پژوهشي(توصیفی- تحلیلی) Research <p> <strong>Received: 11 Feb, 2008 Accepted: 14 Jan, 2009</strong></p><p>  <strong>Abstract</strong> </p><p> <i> <strong>Background &Aims</strong> </i><strong>: </strong>Shivering is a common problem after general anesthesia. This condition increases the oxygen consumption. Therefore prevention of shivering is important particularly in elderly and patients with ischemic heart disease. Dexamethasone decreases the gradient between core and skin temperature and modifies the inflammatory response. The goal of this study was to determine the efficacy of dexamethasone on postoperative shivering<strong>.</strong> </p><p> <strong><i> Materials & Methods </i></strong><strong>: </strong>In a prospective double–blind clinical trial 100 ASA I and II patients aged 20-50yr scheduled for elective cholecyctectomy under general anesthesia were randomly assigned to receive either dexamethasone 0.15 mg/ kg or placebo after induction of anesthesia. All patients received same medication and standard monitoring during maintenance of anesthesia. Rates of shivering analysis were preformed by using Chi Square tests. </p><p> <strong><i> Results </i></strong><strong>: </strong>The incidence of shivering was significantly lower in dexamethasone group than placebo group. (18.7% vs. 36% and p=0.009). There was no significantly difference regarding severity of shivering among two groups. </p><p> <strong><i>Conclusion</i></strong><strong> : </strong>Dexamethasone is an effective drug for prevention of postoperative shivering and its use is recommended. </p><p> <strong><i> Keywords </i></strong><strong>: </strong>Dexamethasone, Postoperative shivering, General anesthesia, <a href="http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=Cholecystectomy&spell=1">Cholecystectomy </a></p><p>  </p><p> <strong><i> Address: </i></strong><strong></strong>Department of Aneshthesiology, Imam Khomeini Hospital, Urmia, Iran. </p><p> <strong> Tel: </strong>(+98441)3468967 </p><p>  </p><p> <strong><i> E-mail: </i></strong>ar_Mahoori@yahoo.com </p><p>  </p><p> <strong> Source </strong>: UMJ 2009: 20(1): 083 ISSN: 1027-3727 </p><br clear="all" > دگزامتازون، شیورینگ بعد از عمل، بی­هوشی عمومی، کوله سیستکتومی Dexamethasone, Postoperative shivering, General anesthesia, Cholecystectomy 62 66 http://umj.umsu.ac.ir/browse.php?a_code=A-10-3-59&slc_lang=fa&sid=1 دکتر حیدر نوروزی‌نیا 370031947532846001435 370031947532846001435 No دکتر فرهاد حشمتی 370031947532846001436 370031947532846001436 No دکتر میرموسی آقداشی 370031947532846001437 370031947532846001437 No دکتر علیرضا ماهوری ar_Mahoori@yahoo.com 370031947532846001438 370031947532846001438 Yes دکتر ابراهیم حسنی 370031947532846001439 370031947532846001439 No دکتر ارشد علیزاده 370031947532846001440 370031947532846001440 No
