探讨套囊气管导管在儿科重症监护室中的应用价值。方法使用BicoreCP—100呼吸监护仪测定27例套囊导管和31例无套囊导管插管的呼吸衰竭儿呼吸力学指标，并观察插管并发症。结果两组患儿的呼吸频率、呼出潮气量、漏气车、吸气峰压、气体流速及患儿呼吸功在插管当天及拔管前检测均有显著性差异（P＜0．01），换管率在无套囊组多于套囊组；插管保留时间、病死率、气压伤以及拔管后喘鸣发生率两组差异无显著性。结论在急性呼吸衰竭婴幼儿中应用套囊导管可减少气管周围漏气．降低吸气峰压，气体流速及患者呼吸功，改善肺地通气，减少换管，不增加副作用。建议儿科重症监护室中使用套囊气管导管。
To investigate the value of cuffed tracheal tube in pediatric intensive care unit. Methods Bicore CP-100 respirator was used to detect the respiratory mechanics of 27 cases of cuffed duct and 31 cases of non-cuffed ductal respiratory failure. The complications of intubation were observed. Results The respiratory rate, exhaled tidal volume, air leak car, peak inspiratory pressure, gas flow rate and respiratory function in both groups were significantly different on the day of intubation and extubation (P <0.01) , And the tube replacement rate was higher in the cuff-free group than in the cuff group. There was no significant difference in the retention time, mortality, barotrauma and the incidence of wheezing after extubation. Conclusions The use of a cuff catheter in infants with acute respiratory failure can reduce air leaks around the trachea. Reduce peak inspiratory pressure, gas flow and respiratory work, improve lung ventilation, reduce tube change, without increasing side effects. It is recommended to use a cuffed endotracheal tube in a pediatric intensive care unit.
