摘要
高原海拔高，空气氧含量低，小儿急性呼吸衰竭（简称呼衰）发病率高。机械通气是治疗呼衰的一种主要手段。只要患儿①明显呼吸节律不齐或频发者停；②清理气道，合理给氧而缺氧不改善；③吸氧下血气示ＰａＣＯ＿２≥５．３３ｋＰａ，ＰａＯ＿２≤６．０ｋＰａ者均为机械通气指征。机械通气时因缺少心电呼吸监护仪时避免使用肌松剂，以免发生意外。动态监测血气，正确处理合并症是提高呼衰抢救成功率的关键。作者认为：机械通气是小儿急性呼衷的急救措施，而不在视为濒死前的抢救手段。
he morbidity of acute respiratory
failure(ARF) is higher than plain due to the hypoxia at highaltitude.
Mechanical ventilation is a valuable therapeutic method for ARF
treatment at high altitude. The mechanical ventilation is indicated
for:①irregular respiratory rhythm or temporary apnea;②hy-poxemia
not improved after air passage cleaned or oxygen inhaled;③PaCO_2≥5.
33kPa or PaO_2≤6. 0kPa on blood gas analysis during oxygen
inhalation. We consider that the mechanical ventilation isnot only
for the patients at agonal stage but is an emergent management for
pediatric ARF patients,and should be started as early as possible, If
monitoring is not available, the muscle relaxation drugsmust be
avoided to prevent cardiac and respiratory accidents. The key of
successfully treating ARF pa-tients is that analysing the blood gas
at intervals and dealing with the complication correctly.
