摘　　要：目的通过研究气管插管机械通气呼吸窘迫综合征(RDS)早产儿的临床特征,分析拔管失败的危险因素及不良结局,为预防拔管失败提供参考依据。方法回顾统计蚌埠医科大学第一附属医院新生儿重症监护病房(NICU)2017年6月—2022年12月入院治疗的胎龄<32周早产儿临床资料,根据拔管结果分为成功组和失败组,分析失败组的危险因素,比较2组的病情发展与转归。结果共纳入RDS早产儿153例,成功组128例,失败组25例(16.3%)。进行logistic回归分析后发现,出生体重较低(OR=9.215,95%CI:1.153~73.611,P<0.05)、5分钟Apgar评分低(OR=2.769,95%CI:1.681~4.563,P<0.05)、未应用咖啡因(OR=46.353,95%CI:3.489~615.792,P<0.05)、拔管前PaCO 2较高(OR=0.871,95%CI:0.809~0.938,P<0.05)、拔管前PaO 2较低(OR=1.058,95%CI:1.018~1.101,P<0.05)是拔管失败的危险因素。在拔管失败组中,患儿死亡抑或放弃治疗、呼吸机相关性肺炎(VAP)和支气管肺发育不良(BPD)均有较高发生率(P<0.05),且氧疗时间大于成功组(P<0.05)。结论出生体重越低、5分钟Apgar评分越低、未应用咖啡因、较高的PaCO 2和较低的PaO 2是预测RDS早产儿拔管失败的危险因素,早产儿死亡及不良结局的风险会因拔管失败而增加。Objective To study the clinical characteristics of premature infants with respiratory distress syndrome(RDS)by tracheal intubation mechanical ventilation,analyze the risk factors and adverse outcomes of extubation failure,and provide evidence for its prevention.Methods The clinical data from preterm infants(<32 weeks gestational age)admitted to Neonatal Intensive Care Unit(NICU)of the First Affiliated Hospital of Bengbu Medical University from June 2017 to December 2022 were reviewed and analyzed.According to the outcome of tracheal intubation and extubation,they were divided into a successful group and a failed group.The risk factors for extubation failure were analyzed,and the clinical progression and outcomes of the two groups were compared.Results A total of 153 premature infants with RDS were included,with 128 infants in the successful extubation group and 25 infants(16.3%)in the failed extubation group.Logistic regression analysis identified the following significant risk factors for extubation failure:low birth weight(OR=9.215,95%CI:1.153-73.611,P<0.05),and low 5-minute Apgar score(OR=2.769,95%CI:1.681-4.563,P<0.05),no caffeine use(OR=46.353,95%CI:3.489-615.792,P<0.05),high PaCO 2 before extubation(OR=0.871,95%CI:0.809-0.938,P<0.05),and low PaO 2 before extubation(OR=1.058,95%CI:1.018-1.101,P<0.05).The rates of death or abandonment of treatment,ventilator-associated pneumonia(VAP),and bronchopulmonary dysplasia(BPD)were higher in the failed group(P<0.05).Additionally,the failed group required longer oxygen therapy compared to the successful group(P<0.05).Conclusion Lower birth weight,lower 5-minute Apgar score,no caffeine use,elevated PaCO 2,and reduced PaO 2 are significant predictors of extubation failure in premature infants with RDS.Extubation failure increases the risk of death and adverse outcomes in these infants.
