目的观察生脉注射液预防早产儿原发性呼吸暂停(PIA)的疗效。方法将有发生原发性呼吸暂停危险的早产儿89例随机分成治疗组和对照组,在常规治疗的基础上治疗组加用生脉注射液静点,比较两组PIA的发生率。同时观察两组早产儿的一般状况及周期性呼吸情况。结果治疗组PIA发病率为34.09%,对照组PIA发病率为57.78%,两组相比有显著性差异(χ2=5.024,P<0.05)。且治疗组早产儿的周期性呼吸次数减少,时间短。结论生脉注射液预防早产儿呼吸暂停有一定疗效。 Objective To observe the effect of Shengmai injection in preventing premature infants with primary apnea (PIA). Methods Eighty-nine premature infants who were at risk of primary apnea were randomly divided into treatment group and control group. On the basis of routine treatment, the treatment group was given Shengmai injection intravenous injection to compare the incidence of PIA in both groups. At the same time, observe the general condition and periodic respiration of the two groups of preterm infants. Results The incidence of PIA was 34.09% in the treatment group and 57.78% in the control group. There was significant difference between the two groups (χ2 = 5.024, P <0.05). In the treatment group, the number of periodic respiration in preterm infants decreased and the time was short. Conclusion Shengmai injection to prevent apnea in preterm children have a certain effect.
