摘　　要：目的:探讨高频通气手术系统在咽喉气管手术中应用的有效性及安全性。方法:将符合美国麻醉医师协会分级标准Ⅰ~Ⅱ级,且拟在全身麻醉下行择期咽喉气管手术的60例患者随机分为高频喷射通气(HFJV)组和间歇正压通气(IPPV)组各30例。HFJV组借助高频喷射呼吸机行HFJV,IPPV组通过小口径气管导管接麻醉机行IPPV。在麻醉前(T0)、支撑喉镜放置成功后(T1)、通气5 min后(T2)及支撑喉镜取出5 min后(T3)各时间点记录血流动力学指标,在T0、T2和T3各时间点测量动脉血气指标,同时记录平均气道压、呼气末二氧化碳浓度、手术视野质量、总出血量、手术时间和苏醒时间,对比2组方案对上述指标的影响并记录不良事件发生情况。结果:HFJV组的平均气道压、平均总出血量明显低于IPPV组(P<0.01),而且HFJV组的平均手术视野质量明显更好(P<0.01),但对血流动力学、动脉血气等指标的影响与IPPV组相比差异均无统计学意义(P>0.05)。2组均未发生严重不良事件。结论:高频通气手术系统可有效地应用于咽喉气管手术,减少术中出血量,改善手术视野质量,且无明显不良反应。Objective: The effectiveness and safety of high frequency ventilation system in laryngopharyngeal and tracheal surgery is discussed. Methods: According to The American Society of Anesthesiologists Ⅰ-Ⅱ level, 60 cases of selective throat and tracheal surgery undering general anesthesia were randomly divided into high frequency jet ventilation group(group HFJV) and intermittent positive pressure ventilation group(IPPV group), with 30 cases in each group. Group HFJV was treated with HFJV and group IPPV with a small caliber endotracheal tube connected to an anesthesia machine was treated with IPPV.Before anesthesia(T0), after the success of the laryngoscope placed(T1), 5 minites after ventilation(T2) and 5 minites after the laryngoscope removed(T3), hemodynamic parameters were recorded at each time point, in T0, T2 and T3 record, arterial blood gas index, the patient’s airway pressure, end-expiratory carbon dioxide concentration, surgical field quality and total blood loss, operating time and awakening time were recorded and compared between the two groups. Results: The average airway pressure and intraoperative average total blood loss of group HFJV were significantly lower than that of group IPPV(P<0.01), and the average operative field quality of group HFJV was significantly better(P<0.01), but there was no statistical significance in the effects on hemodynamics, arterial blood gas and other indicators compared with group IPPV(P>0.05). No serious adverse events occurred in 2 groups. Conclusion: HFJV system can be used effectively in laryngopharyngeal and tracheal surgery, reducing intraoperative blood loss and improving surgical field of vision without obvious adverse reactions.
