术终采用间歇指令通气对全麻患者早期苏醒的影响

The Influence of Intermittent Mandatory Ventilation on Early Resuscitation of Patients with General Anesthesia at the End of Operati on

目的探讨全麻术终采用间歇指令通气(IMV)是否有利于患者的早期苏醒。方法将病人分为两组,在全麻术终患者有微弱自主呼吸时,分别采用追加肌松药(维库溴铵)或使用IMV呼吸模式的处理方法,记录患者生命体征、气道压变化及苏醒时间。结果术终采用IMV的患者苏醒时间为(8·76±16·43)min较追加肌松药的患者苏醒时间(11·98±32·87)min明显苏醒迅速(P<0·01)。结论术终采用IMV能够减少肌松药用量,使患者自主呼吸得到充分恢复,有利于患者早期苏醒,防止术后呼吸抑制。

Objective To observe if intermittent mandatory ventilation （IMV） is propitious to the early resuscitation of the patients with general anesthesia at the end of operation. Methods The patients were divided into two groups which were administered respectively with a muscle relaxant, vecuronium bromide as superaddition and with IMV at the end of operation when the patients came to slight autonomic respiration. Their life signs, airway pressure changes and resuscitation time were recorded. Results The resuscitation time of IMV group was 8. 76 ± 16.43 min, significantly shorter than that （ 11.98 ± 32. 87 min） of X group （ P 〈 0. 01 ）, Conclusion The application of IMV at the end of operation fully reastores the autonomic respiration and is helpful to the early resuscitation of the patients with general anesthesia, so that post-operative respiratory inhibition can be prevented.
