Newly born preterm infants often require respiratory support. Various approaches have been taken to provide this support, including elective intubation and ventilation, prophylactic surfactant and continuous positive airway pressure (CPAP). Elective intubation and ventilation allow the clinician to take control of the baby's airway and reduce the support as tolerated. Surfactant can be administered prophylactically to prevent lung injury and respiratory complications. Many neonatologists, however, advocate a less aggressive approach to the provision of support, which includes the application of early nasal CPAP with intubation and ventilation only if necessary. Avoiding intubation may be effective in minimising ventilator-induced lung injury, but withholding surfactant may be detrimental to the infant. In this paper, we examine the advantages and disadvantages of the different approaches that can be taken in providing respiratory support to preterm neonates shortly after birth and examine some strategies that integrate them.
新生早产儿常常需要呼吸支持。为提供这种支持已采取了各种方法,包括选择性插管和通气、预防性使用表面活性剂以及持续气道正压通气(CPAP)。选择性插管和通气使临床医生能够控制婴儿的气道,并根据耐受情况减少支持。表面活性剂可预防性给药以预防肺损伤和呼吸并发症。然而,许多新生儿科医生主张采用一种不太激进的支持方法,即仅在必要时才进行早期经鼻CPAP并插管和通气。避免插管可能有效减少呼吸机诱导的肺损伤,但不使用表面活性剂可能对婴儿有害。在本文中,我们探讨了出生后不久为早产儿提供呼吸支持时可采用的不同方法的优缺点,并研究了一些将它们整合起来的策略。
