Abstract

Prediction of pulmonary hypoplasia after midtrimester preterm prelabour rupture of membranes (PPROM) is important for optimal management. We performed a systematic review to assess the capacity of clinical parameters to predict pulmonary hypoplasia. A systematic literature search in EMBASE and MEDLINE was performed to identify articles published on pulmonary hypoplasia in relation to midtrimester PPROM. Articles were selected when they reported on one of the following clinical parameters - gestational age at PPROM, latency period and degree of oligohydramnios - and when they allowed the construction of a two-by-two table comparing at least one of three clinical parameters to the occurrence of pulmonary hypoplasia. The selected studies were scored on methodological quality, and sensitivity and specificity of the tests in the prediction of pulmonary hypoplasia and lethal pulmonary hypoplasia were calculated. Overall performance was assessed by summary receiver operating characteristic (sROC) curves that were constructed with bivariate meta-analysis. We detected 28 studies that reported on the prediction of pulmonary hypoplasia. Prediction of lethal pulmonary hypoplasia could be analysed separately in 21 of these studies. The quality of the included studies was poor. The estimated sROC-curves showed that gestational age at PPROM performed significantly better than the two other parameters in the prediction of pulmonary hypoplasia. The accuracy in the prediction of lethal pulmonary hypoplasia was similar. In women with midtrimester PPROM, pulmonary hypoplasia can be predicted from the gestational age at PPROM. This information should be used in the management of women with early PPROM.
