新生儿呼吸衰竭人工呼吸器治疗及有关呼碱调节的探讨

MECHANICAL VENTILATORY THERAPY AND MANAGEMENT OF RESPIRATORY ALKALOSIS IN RESPERATORY FAILURE OF NEW-BORN

本文通过对我院两年来34例呼吸器供氧治疗呼吸衰竭（呼衰）作了总结，结果：1．鼻塞CPAP17例，全部成活。IPPV＋PEEP（CPPV）17例，成活12例，CPPV成活率为70．6％。2．对呼吸性碱中毒（9／17）原因及处理加以分析，过度通气、初调值偏高为主要原因，血气分析不及时造成呼碱程度加重。处理上除调节PIP，RR，F和I：R外还可使用IMV。3．对IMV使用指征加以扩充：轻度呼衰，呼吸器撤离前的过渡和伴随自主呼吸的呼吸性碱中毒可首选使用IMV。

Froin Nov. 1992 to Oct. 1993 34 cases respiratory fallure (RF) were treated by ventilatar. The results showed: 1. 17 cases used CPAP and IPPV+PRRP (CPPV) was used for 17 cases, 28 cases of them, survived, survivcd rate was 87.4% and survived rate of 17 cases by CPPV was 70. 6%. 2. The causes and treatments of 7 cases respiratory alkalosis was analysed. over ventllation was a mainly cause. In our case. We analysed that the primitive adjustment (PIP, RR) was higher and blood gas analysis was not in time. For treatment of respiratory alkalosis. Mechanical ventilator of IMV was used besides reduction of PIP, RR or F and increase of I: R. 3. We suggested that IMV was the first method of sightly RF and respiratory alkalosis with breath and withdrawal of ventilatory support
