病人自控镇痛技术在结肠镜息肉切除术中的应用

Application of Patient Controlled-analgesia in Colorectal Polypi Resection

目的观测病人自控镇痛(PCA)技术在结肠镜息肉切除术患者的安全性和有效性.方法60例ASAⅠ-Ⅱ级行结肠镜息肉切除术患者随机分为对照组(C组)和PCA组.C组未行麻醉处理;PCA组以PCA泵静脉输注瑞芬太尼.观察并记录患者入室后、入镜时、操作中、操作结束及离院时的HR、MAP、SpO2、RR,术前、术中及术后的血糖值,操作时间、治疗成功率、不良反应、VAS评分、患者和术者满意度.结果与C组相比,PCA组操作时间短(P<0.05),VAS评分低(P<0.01),患者和术者满意度高(P<0.01,P<0.05),术中MAP、RR和血糖稳定(P<0.01),不良反应发生率低(P<0.01).结论PCA技术用于结肠镜息肉切除术镇痛效果完善,安全性好,值得在临床推广应用.

Objective To study the safety and feasibility of patient controlled-analgesia （PCA） in colorectal polypi resection. Methods 60 patients with ASA Ⅰ - Ⅱ undergoing colorectal polyp/resection were randomly divided into two groups： control group （group C） （n = 30） and PCA group （n = 30）. In PCA group , remifentanil was injected by PCA system. MBP, HR, SpO2, RR, blood sugar, operation duration, side effects, postoperative VSA and satisfaction were recorded. Results Operation duration was shorter （P 〈 0.05） , postoperative VSA was lower （P 〈 0.01） , satisfaction of the patients and operators was higher in PCA group than in control group （P〈0.01, P〈0.05）. MAP, RR and blood sugar were more stable （P〈0.01） , side effects were less in PCA group than in control group （P〈 0.01 ）. Conclusions PCA in the colorectal polypi resection is effective, painless and safe. So it is worth extending in clinic.
