电子控制镇痛泵用于剖宫产术后镇痛的临床效果分析

Clinical Effect of Electrically Controlled Analgesia Pump on Patients Undergoing Cesarean Section

目的:观察研究用于剖宫产术后患者的电子控制镇痛泵与普通弹力输注泵的临床效果差异。方法:100例拟于硬膜外麻醉下行剖宫产者,随机分为电子组(n=50),设定PCA量为3 mL,锁定时间15 min,基础流速1 mL/h;普通组(n=50),PCA量0.5 mL,锁定时间15 min,基础流速2 mL/h。2组药袋内均加入芬太尼1 mg,加生理盐水至100 mL,于手术结束后进行术后自控静脉镇痛。观察并记录2组患者48 h内发生的明显宫缩痛的次数和切口痛的次数、镇痛泵走空的时间和48 h后剩余药量、发生的不良反应及患者满意度,以及术后2、8、12、24、48 h镇痛泵按压频次。结果:2组患者术后不同时段镇痛泵按压次数无明显差异(P>0.05)。术后48 h内,2组患者中出现明显术后切口疼痛的次数无明显差异(P>0.05)。电子组术后发生明显宫缩疼痛明显少于普通组(P<0.05)。2组均未发现与术后镇痛明显相关的不良反应。电子组患者镇痛泵走空时间较普通组明显减短(P<0.05),2组患者48 h后镇痛泵内剩余药量无明显差异(P>0.05)。电子组患者满意度明显高于普通组(P<0.05)。结论:电子控制镇痛泵通过增加剖宫产术后患者自控镇痛的自主性,减少了患者术后宫缩痛,使患者更满意。

Objective To observe and research the different effects of the electronic analgesia pump and elastomeric pump on the patients going through cesarean section. Methods One hundred of patients got to undergo cesarean section with epidural anesthesia were equally dived into two groups, the electronic group and control group. In the electronic group, the PCA dose was set as 3 mL, the lock time as 15 min and the basic flow as 1 mldh; and in the control group, the PCA dose was set as 0.5 mL, the lock time as 15 min and the basic flow as 2 mL/h. The dropping bags were filled with 1 mg fentanyl and 100 mL sodium chloride, respectively. Self-controlled intravenous analgesia was performed after the operation. Such indexes were recorded as the times of obvious uterus systole pains and incision pains, the idling time and the residual drug 48 h after the operation, adverse effect, patient satisfaction and the frequencies of pressing the pumps 2, 8, 12, 24 and 48 h after the operation. Results For the two groups, there was no significant differences between the times of pressing the pumps after the operation and between the times of obvious incision pains 48 h after the operation, with P〉0.05. The uterus systole pains in the electronic group were significantly less than those in the control group, with P〈0.05, and there was no obvious adverse effect related to the post-operative analgesia. The idling time in the electronic group was significantly shorter than that in the control one, with P〈0.05. There was no significant difference between the residual drugs 48 h after the operation in the two groups, while significantly higher satisfaction in the electronic group than that in the control one. Conclusion For the patients after cesarean section, self-controlled analgesia by the electrical pump makes the uterus systole pains decreased and the satisfaction increased.
