目的:探讨催产素不同给药方式对剖宫产患者血流动力学的影响。方法:选取笔者所在医院收治的80例硬膜外阻滞行剖宫术患者,采用随机数字表法将其分为对照组和试验组,各40例。对照组采用催产素20 IU及生理盐水500 ml静脉滴注,滴速20 ml/min;试验组采用催产素10 IU及生理盐水100ml静脉滴注,滴速10 ml/min,后改为催产素10 IU及生理盐水500 ml静脉滴注,滴速150 ml/h。记录患者麻醉前、使用催产素前、使用催产素后10 min和手术结束时心率(HR)、收缩压(SBP)、舒张压(DBP)。结果:两组各时间点收缩压和舒张压均较麻醉前降低,差异有统计学意义(P<0.05)。两组使用催产素后10 min心率均较麻醉前增快,差异有统计学意义(P<0.05)。使用催产素后10 min试验组心率低于对照组,差异有统计学意义(P=0.006)。结论:催产素影响剖宫产患者血流动力学,负荷剂量复合维持量催产素对剖宫产患者血流动力学的影响较小。
Objective: To investigate the effects of different oxytocin administration on hemodynamics in patients with cesarean section. Methods: Eighty cases of epidural block cesarean section were selected from the hospital where the author was treated. They were divided into control group and trial group with 40 cases in each group by random number table. In the control group, 20 IU oxytocin and 500 ml saline were intravenously dripped at a drip rate of 20 ml / min. In the test group, 10 IU of oxytocin and 100 ml of saline were intravenously dripped at a drip rate of 10 ml / min and then changed to oxytocin 10 IU and saline 500 ml intravenous drip, drip rate 150 ml / h. The heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded before anesthesia, before oxytocin, at 10 min after oxytocin and at the end of surgery. Results: Systolic blood pressure and diastolic blood pressure in both groups were lower than before anesthesia, the difference was statistically significant (P <0.05). The heart rate of 10 min after oxytocin administration in both groups increased faster than before anesthesia, the difference was statistically significant (P <0.05). The oxytocin 10 min after the test group heart rate was lower than the control group, the difference was statistically significant (P = 0.006). CONCLUSION: Oxytocin affects the hemodynamics of patients with cesarean section. The loading dose of oxytocin has less effect on the hemodynamics of patients with cesarean section.
