目的观察术前禁食禁饮时间的长短对择期人工流产术麻醉效果的影响。方法将200例无痛人工流产妇女随机均分为两组,实验组(A组)术前禁食6～8h,禁饮2～3h,对照组(B组)术前禁食12h,禁饮6h。两组患者均在丙泊酚、布托啡诺、戊乙奎醚联合麻醉下手术。记录两组患者麻醉前(T0)、术后1min(T1)、术后5min(T2)、术后10min(T3)血压(MAP)、心率(HR)、脉搏血氧饱和度(SPO2)的变化,并记录丙泊酚的用量、苏醒时间及不良反应。结果与T0比较:A、B两组MAP、SPO2在T1点均明显下降,HR升高(P<0.05)。SPO2在T1点A组18%、B组47%患者低于95%,T2点A组5%、B组23%患者仍低于95%,组间比较差异有统计学意义(P<0.05)。丙泊酚用量A组为(2.5±0.5)mg/kg,B组为(1.9±0.4)mg/kg,两组比较差异有统计学意义(P<0.05)。苏醒时间A组为(6.5±2.4)min,B组为(12.0±6.5)min,两组比较差异有统计学意义(P<0.05)。结论人工流产术时,术前8h禁食固体食物、2h禁饮,安全可行,能降低患者的不适反应,提高患者的麻醉手术耐受能力。
Objective To observe the effect of preoperative fasting forbidden time on the anesthetic effect of elective abortion. Methods 200 cases of painless abortion women were randomly divided into two groups. The experimental group (Group A) was fasted for 6 ~ 8h, forbidden to drink for 2 ~ 3h, while the control group (Group B) 6h. Two groups of patients in propofol, butorphanol, penehyclidine anesthesia under the operation. The changes of blood pressure (MAP), heart rate (HR) and pulse oxygen saturation (SPO2) were recorded before anesthesia (T0), 1min after operation (T1), 5min after operation (T2) and 10min after operation , And record the amount of propofol, wake time and adverse reactions. Results Compared with T0, MAP and SPO2 in group A and B decreased significantly at T1 and HR increased (P <0.05). SPO2 in group A was 18% in group A, 47% in group B was lower than 95%, 5% in group A and T2, and 23% in group B was still lower than 95%. There was significant difference between groups (P <0.05) . The dosage of propofol was (2.5 ± 0.5) mg / kg in group A and (1.9 ± 0.4) mg / kg in group B, the difference was statistically significant (P <0.05). The awakening time was (6.5 ± 2.4) min in group A and (12.0 ± 6.5) min in group B, respectively. The difference between the two groups was statistically significant (P <0.05). Conclusions In abortion, fasting solid food 8h before operation and banning 2h before surgery are safe and feasible, which can reduce the patient’s discomfort reaction and improve the patient’s tolerance to anesthesia.
