摘要 有报道腹腔镜胆囊切除术(LC)后病人恶心呕吐(PONV)的发生率在53%~72%[1,2],PONV不但增加病人的痛苦,还可导致脱水、碱中毒和电解质失调等内环境紊乱,延长病人住院时间和增加医疗费用.麻醉前给予镇吐药可以预防PONV的发生.具有高度选择性的5-HT3受体拮抗剂恩丹西酮可对抗由多巴胺受体和运动导致的呕吐,并能在手术后较长时间内保持较高的血药浓度,术前静脉注射能有效预防全麻术后的PONV[3,4],且没有其他镇吐药所常见的镇静、焦虑、锥体外系损害等副作用.地塞米松可降低化疗后呕吐的发生率,预防儿科斜视矫正、扁桃体切除术、增殖腺切除术和较大妇科手术的术后PONV[5].LC后PONV的诱发因素多样,确切机制尚不明确.本研究旨在比较地塞米松、恩丹西酮单独或联合应用预防LC后病人PONV的效果,寻求临床较理想的药物组合.
