摘要
目的 :观察慢性呼吸衰竭患者容许性高碳酸血症通气 (PHC)的治疗效果。方法 :应用低潮气量 (8± 0 6ml/kg) ,容许一定限度的高碳酸血症 (PaCO2<8 77± 0 13,pH >7 2 ) ,动态观察气道峰压、血压和血气变化。结果 :PHC治疗前后PaCO2 、pH比较差异均有显著性 (P <0 0 1)。除 4例 2～ 6h内血压下降 ,2 4h逐渐稳定外 ,患者均无明显心率改变和气压伤等并发症。意识转清时间为11 6 2± 7 2 9h。总治愈率为 94%。结论 :PHC治疗慢性呼吸衰竭 ,可有效地改善动脉血氧合 ,保持一定水平PaCO2 和pH ,有利于撤机 。
Objictive: To observate over the treatment result of chronic respiratory failure by permissible hyper carbohemia (PHC). Method: we have accepted low tidal volume (8±0 6ml/kg),hyper carbohemia was permissible by a certein degree (PaCO 2<8 77±0 13,pH>7 2),peak pressure in respiratory tract,blood pressure and blood gas analysis were under dynamic observation.Result: before and after PHC therapy,PaCO 2、pH all have significant diffevence (P<0 01).All patients showed no such complications as heart rate change and air pressure injury except 4 cases with low blood pressure durirg first 2-6 hrs and reacquired stability in 24 hrs;Time required for regaining consciousness is 11 62±7 29 hrs curative ratio is 94%.Conclusion: PHC can inprove artery blood oxygentability,remain permissible level of PaCO 2 and pH,be helpful for removal of respiratory machvine,and with less complication.
