摘要
目的 :评价鼻塞气道正压通气 (CPAP)对小儿心脏术后急性呼吸衰竭的治疗作用。 方法 :18例心脏术后合并急性呼吸衰竭患儿 ,年龄 9个月～ 6岁 ,观察 CPAP前后血压、心率、呼吸频率及动脉血气的变化。 结果 :与 CPAP应用前相比 ,CPAP后 1小时及 4小时的呼吸频率由 5 1± 10次 /分分别减慢至 45± 9次 /分及 39± 12次 /分 (P<0 .0 1) ;动脉血氧分压由 71± 14mm Hg(1mm Hg=0 .133k Pa)分别上升至 10 8± 34mm Hg及 110± 35 mm Hg(P均<0 .0 1) ;二氧化碳分压由 5 0± 7mm Hg分别下降至 45± 6 mm Hg及 43± 13mm Hg,循环状况趋于稳定。 结论 :合理应用鼻塞 CPAP可迅速改善心脏术后急性呼吸衰竭患儿的通气及换气功能 ,减少呼吸功 ,可作为再次气管插管前的补救措施之一。
Objective:To assess the effects of nasal coninuous positive airway pressure(CPAP) breathing on acute respiratory failure after paediatric open heart surgery. Method:In 18 children with acute respiratory failure age ranged between 9 months and 6 years.The changes of blood pressure,heart rate,respiratory rate and arterial blood gas before and after nasal CPAP ventilation were observed. Results:After 1 hour and 4 hours nasal CPAP,the respiratory rate decreased from 51±10 to 45±9 and 39±12( p <0 01) respectively.PaO 2 increased from 71±14 mmHg to 108±34 mmHg and 110±35 mmHg( p <0 01),the PaCO 2 decreased from 50±7 mmHg to 45±6 mmHg and 43±13 mmHg.The circulatory condition became stable. Conclusion:The correct use of Nasal CPAP may improve ventilation and gas exchanges in paediatric patients with acute respiratory failure,and it should be considered as a corrective measure before endotracheal intubation.
