【摘要】 目的 应用诱发性排痰法协助心脏手术后患儿清除呼吸道分泌物。方法 观察286例患儿的排痰有 效率、 咳嗽后痰鸣音消失情况及术后肺不张的发生情况，并对29例拔除气管插管后动脉血气分析有 CO2潴留的患儿作了2种排痰法的对比性研究。结果 排痰有效率为94.06%(269/286)，痰 鸣音完全消失率为90.21%(258/286)，肺不张的发生率为0.7%(2/286)，与经鼻负压吸痰法 比较，两者纠正CO2潴留效果有显著性差异(P<0.05)。结论 诱发性排痰法 能有效地协助患儿咳嗽排痰，纠正高碳酸血症，预防阻塞性肺不张的发生。更多还原

【Abstract】 ： Objective Using the method of inductive expectoration to clean the product of r espiratory tract after open-heart operation.Method The efficiency of expectorat ion and apearance of obstractive pulmonary atelectasis were observed in 286 pedi atric patients.The comparative study was performed in 29 cases patients with hyp ercarboxemia by blood gas analysis.Results The efficiency of inductive expector ation is 94.06%(269/286),the percentage of complete disappearance of wheeze is 9 0.21%(258/286).The percentage of atelectasis is 0.70%(2/28 6).There was a difference in correction effect on hypercarboxemia between two gr oups.Conclusion The method of inductive expectoration can effectively assist th e children to clean the secretion of respiratory tract,treat hypercapnia and prevent the apperance of obstructive atelectasis. =更多还原
