Respiratory distress syndrome (RDS) is defined as acute respiratory distress caused by surfactant deficiency that disturbs gas exchange in preterm infants. It is one of the most common neonatal problems and has been considered to be the most common cause of mortality and morbidity in preterm babies.
In this study, different variables were studied to predict factors for INSURE failure that might help in choosing infants for this procedure early.
Sixty three (63) patients were enrolled in this study as they met the inclusion criteria. All neonates were intubated briefly less than 2 hours, given natural surfactant in the dose of 3 ml/kg. As soon as it was appropriate and the neonate was stable in the form of normal heart rate and oxygenation, extubation was done and the baby connected to NCPAP at a pressure of 6 cmH2O. INSURE failure was considered if the patient needed mechanical ventilation for more than 72 hours while INSURE success was considered if we were able to wean the patient from CPAP or if the patient didn't need mechanical ventilation in the first 72 hours after surfactant administration. The indications for mechanical ventilation after INSURE procedure were respiratory distress with desaturation (02 sat less than 90%), recurrent apnea, Pco2 more than 60 mmHg.
Since INSURE procedure is being largely applied in the neonatal intensive care units, it is important to determine the candidate neonate for this procedure with the minimum failure rate. Although the sample of our study is small, but we can suggest that neonate with gestational age less than 28, birth weight less than 1000 gm, umbilical PH of less than 7, low Apgar score and anemic patients are at high risk for INSURE failure.
Early diagnosis of PDA and IVH is essential to avoid INSURE method in these patients.
呼吸窘迫综合征(RDS)被定义为由表面活性物质缺乏引起的急性呼吸窘迫,这会干扰早产儿的气体交换。它是最常见的新生儿问题之一,并且一直被认为是早产儿死亡和发病的最常见原因。
在本研究中,对不同变量进行了研究,以预测INSURE失败的因素,这可能有助于早期选择适合该程序的婴儿。
63名符合纳入标准的患者被纳入本研究。所有新生儿均进行了少于2小时的短暂插管,给予3ml/kg剂量的天然表面活性物质。一旦情况合适且新生儿心率和氧合正常,即进行拔管,并将婴儿连接到压力为6cmH2O的无创持续气道正压通气(NCPAP)。如果患者需要机械通气超过72小时,则认为INSURE失败;如果我们能够使患者从CPAP撤机,或者患者在给予表面活性物质后的前72小时内不需要机械通气,则认为INSURE成功。INSURE程序后机械通气的指征为伴有血氧饱和度降低的呼吸窘迫(血氧饱和度低于90%)、反复呼吸暂停、二氧化碳分压高于60mmHg。
由于INSURE程序在新生儿重症监护病房中广泛应用,因此以最低失败率确定适合该程序的新生儿非常重要。尽管我们研究的样本量较小,但我们可以认为,胎龄小于28周、出生体重小于1000克、脐动脉血pH值小于7、阿氏评分低以及贫血的新生儿发生INSURE失败的风险较高。
对动脉导管未闭(PDA)和脑室内出血(IVH)的早期诊断对于避免在这些患者中使用INSURE方法至关重要。
