目的:观察围术期输注右美托咪定(Dexmedetomidine ,Dex)对全麻术后镇痛药吗啡用量的影响。方法:选择40例ASAⅠ~Ⅱ级,拟在全麻下行全子宫切除术的患者,随机分为对照组(NS组)和右美托咪定(DEX )组。DEX组术前静脉给予右美托咪定负荷剂量1μg/kg ,继以4μg/h持续输注至术后48h。NS组给予同等容量的生理盐水以同样技术予以输注。术后应用吗啡静脉自控镇痛(PCIA),记录患者首次要求镇痛的时间(患者主观VAS评分大于4cm时),术后4、8、18、24、48h疼痛评分(VAS),镇静评分(OAA/S),吗啡用量及术后恶心呕吐情况。结果:从手术结束到患者首次要求镇痛的时间,DEX组[(31.45±6.25)min]比NS组[(21.00±4.36)min]显著延长(P<0.01)。DEX组术后48h内吗啡的总用量(24.50±2.77)mg ,显著低于NS组(33.47±2.79)mg(P<0.01)。术后恶心呕吐的发生率DEX组与NS组分别为10%和25%(P<0.05)。结论:全麻下行子宫切除术的患者,围术期输注DEX可延长患者术后首次要求镇痛的时间,减少术后48h内吗啡的用量及术后恶心呕吐的发生率。
目的:觀察圍術期輸註右美託咪定(Dexmedetomidine ,Dex)對全痳術後鎮痛藥嗎啡用量的影響。方法:選擇40例ASAⅠ~Ⅱ級,擬在全痳下行全子宮切除術的患者,隨機分為對照組(NS組)和右美託咪定(DEX )組。DEX組術前靜脈給予右美託咪定負荷劑量1μg/kg ,繼以4μg/h持續輸註至術後48h。NS組給予同等容量的生理鹽水以同樣技術予以輸註。術後應用嗎啡靜脈自控鎮痛(PCIA),記錄患者首次要求鎮痛的時間(患者主觀VAS評分大于4cm時),術後4、8、18、24、48h疼痛評分(VAS),鎮靜評分(OAA/S),嗎啡用量及術後噁心嘔吐情況。結果:從手術結束到患者首次要求鎮痛的時間,DEX組[(31.45±6.25)min]比NS組[(21.00±4.36)min]顯著延長(P<0.01)。DEX組術後48h內嗎啡的總用量(24.50±2.77)mg ,顯著低于NS組(33.47±2.79)mg(P<0.01)。術後噁心嘔吐的髮生率DEX組與NS組分彆為10%和25%(P<0.05)。結論:全痳下行子宮切除術的患者,圍術期輸註DEX可延長患者術後首次要求鎮痛的時間,減少術後48h內嗎啡的用量及術後噁心嘔吐的髮生率。

Objective :To observe effects of dexmedetomidine (Dex )on the morphine requiement during postoperative analgesia .Methods :Forty ASA Ⅰ ~ Ⅱ undergoing elective abdominal hysterectomy with general anesthesia adult pa-tients were randomly divided to 2 groups :group 1 normal saline group(NS) ,n1 =20 ,group 2 dexmedetomidine(DEX) , n2 =20 ,the patients in group DEX received Dex 1μg/Kg before start of surgery and 4μg/h for the next 48h .The pa-tients in group NS received the same volume of saline .Postoperative patient-controlled intravenous analgesia (PCIA ) with morphine started when subjective pain intensity (visual analog scale ,VAS)was>4cm .VAS and sedation status (OAA/S) were assessed at 4 ,8 ,18 ,24 and 48h during postoperative period .Morphine consumption and complications during 48h after operation were recorded .Results:Morphine consumption was significantly lower in group DEX (24 .50 ± 2.77)mg than that in group NS(33 .47 ± 2 .79)mg in 48h PCIA(P<0 .01) .The mean time to initiation of PCIA was significantly longer in group DEX(31 .45 ± 6 .25)min than that in group NS(21 .00 ± 4 .36)min(P<0 .01) .The inci-dence of postoperative nausea and vomiting was significantly less in group DEX (P<0 .05) .Conclusion:Perioperative use of Dex intravenously significantly reduces postoperative morphine consumption and incidence of nausea and vomi-ting in the patients given PCIA .
