摘要:

目的 观察阿片类药物对老年患者经尿道激光碎石术苏醒质量的影响。 方法 择期经尿道激光碎石手术患者134例,年龄65~79岁,ASA分级Ⅰ、Ⅱ级,采用随机数字表法分为3组:瑞芬太尼组(R组)46例、瑞芬太尼+芬太尼组(RF组)44例、芬太尼组(F组)44例。R组,采用丙泊酚和瑞芬太尼靶控输注(target-controlled infusion, TCI)进行麻醉诱导和麻醉维持;RF组,丙泊酚TCI麻醉诱导,静脉注射芬太尼2 μg/kg,丙泊酚+瑞芬太尼TCI麻醉维持;F组,丙泊酚TCI麻醉诱导,芬太尼4 μg/kg,丙泊酚TCI麻醉维持。手术结束后送入PACU,记录患者被转入PACU时(T1)、拔除喉罩前2 min(T2)、拔除喉罩即刻(T3)和拔除喉罩后5 min(T4)4个时间点的MAP、HR,记录拔除喉罩后VAS评分和苏醒期芬太尼用量,记录患者睁眼时间、拔除喉罩时间和PACU驻留时间。 结果 麻醉苏醒期间R组在T1~T3时点MAP[(110±18)、(122±13)、(121±14) mmHg(1 mmHg=0.133 kPa)]和HR[(79±15)、(97±17)、(99±18) 次/min]高于RF组(P<0.05);R组VAS[(1.8±1.4)分]高于RF组[(0.9±0.9)分]和F组[(0.9±0.9)分](P<0.05);R组需芬太尼镇痛患者比例高于其他两组(P<0.05);F组的睁眼时间、拔喉罩时间以及PACU驻留时间比RF组和R组长(P<0.05)。 结论 老年患者经尿道激光碎石术应用丙泊酚复合瑞芬太尼+芬太尼全凭静脉麻醉比丙泊酚单纯复合瑞芬太尼或芬太尼苏醒期间血流动力学平稳、苏醒迅速、术后镇痛效果好。

Abstract:

Objective The current study aimed to evaluate the effects of opioids on recovery quality in elderly patients undergoing transurethral laser lithotripsy. Methods We enrolled 134 patients aged 65-79 y with ASA Ⅰor Ⅱ who underwent laryngeal mask airway anesthesia for elective transurethral laser lithotripsy. The patients were randomly assigned to remifentanil group (group R, n=46), remifentanil and fentanyl combination group(group RF, n=44), fentanyl group(group F, n=44). In group R, propofol and remifentanil was administered by target-controlled infusion(TCI) for anesthesia induction and anesthesia maintenance. In group RF, propofol TCI and fentanyl single-dose 2 μg/kg was administered for anesthesia induction, propofol and remifentanil TCI was administered for anesthesia maintenance. In group F, propofol TCI and fentanyl single-dose 4 μg/kg was administered for anesthesia induction, propofol TCI for anesthesia maintenance. MAP and HR were recorded when patients were sent to the PACU(T1), 2 min before removal of the laryngeal mask airway(T2), the moment of removal of the laryngeal mask airway(T3) and 5 min after removal of the laryngeal mask airway(T4). VAS was evaluated after removal of the laryngeal mask airway and requirement for fentanyl analgesia was evaluated in PACU. Time to eye opening, time to removal of the laryngeal mask airway and length of stay in PACU were recorded and compared. Results MAP [(110±18), (122±13), (121±14) mmHg(1 mmHg=0.133 kPa)] and HR [(79±15), (97±17), (99±18) bpm] were significantly higher in group R than that in group RF(P<0.05). VAS(1.8±1.4) was higher in group R than that in group RF (0.9±0.9) and group F(0.9±0.9). The proportion of patients who needed fentanyl in group R was significantly higher(P<0.05). Time to eye opening, time to removal of the laryngeal mask airway and length of stay in PACU were significantly longer in group F than that in the other two groups(P<0.05). Conclusions Our results showed that the combined use of propofol with fentanyl and remifentanil in elderly patients undergoing transurethral laser lithotripsy who received total intravenous anesthesia provided hemodynamic stability during anesthetic recovery, provided early recovery and adequate postoperative analgesia compared to the administration of propofol in combination with remifentanil or fentanyl alone.
