摘要
目的比较SIMV模式撤机法与直接撤机法在10 kg以下患儿心内直视术后的撤机效果。方法对32例10 kg以下心内直视术后行机械通气的患儿进行回顾性分析,按照撤机方法的不同分为SIMV模式撤机组与直接撤机组。结果两组相比,撤机所需时间差异有显著性意义(P<0.05),SIMV模式撤机法所需的时间更短,并且呼吸机相关性肺炎(VAP)的发生率更低(P<0.05);两组再置管率差异无统计学意义;两种撤机方法撤机前后的心率、呼吸及血压的变化值比较差异均有显著性意义(P<0.05);两种方法撤机前后的PO2、PCO2及pH值的比较,差异均无统计学意义(P>0.05)。结论10 kg以下行心内直视术后的患儿应用SIMV法撤机能够缩短呼吸机辅助的时间和降低呼吸机相关性肺炎的发生率,效果优于直接撤机法。
Objective To compare the clinical effects of two weaning methods of mechanical ventilation for child patients with body weight below 10 kg after congenital ventricular septal defect repair. Method Retrospective analysis of 32 child patients with body weight below 10 kg after congenital ventricular septal defect operative repairt was conducted. Weaning of mechanical ventilation by synchronized intermittent mandatory ventilation (SIMV) and spontaneous breathing trials. Result Weaning of mechanical ventilation by SIMV could save weaning time (P〈0. 05) and reduced ventilator associated pneumonia (VAP) (P〈0.05); There was a statistical difference in re-catheterization between two methods (P〉0.05). And there were a statistical difference in changes value of heart rate, respiration and blood pressure, but no difference in PO2, PCO2 and pH (P〉0.05). Conclusion The results suggest that weaning of mechanical ventilation in SIMV can save weaning time and reduce ventilator associated pneumonia.
