abstract

  • Technically expedient repair of CDH defects is desirable. With increasing trend toward thoracoscopic repair, herein we examine physiologic predictors for the need for patch closure (PC) versus primary closure. All neonates who underwent surgical repair of CDH defects in a geographically defined region between 1992 and 2002 were included (n = 210). Two groups of patients were compared, primary repair (PR) versus PC. The 25th quartile was used as a cut off point for continuous variables. Univariate and multivariate logistic regression were performed. One hundred and fifty neonates underwent open PR (71.43%) versus 28.57% had PC. On univariate analyses the following variables were significantly associated with the need for PC: prenatal diagnosis, birth weight <2.7 kg, gestational age <37 weeks, APGAR at 5 min <6, immediate postnatal PCO(2) >34, Immediate oxygen saturation <93%, use of Nitric oxide and the need for high frequency oscillation (HFO). On multivariate analyses, only a PCO(2) >34 and the need for HFO were significantly associated with PC. Neonates with an initial PCO(2) >34 or need HFO pre-operatively should be excluded from attempts to repair the CDH thoracoscopically based on their higher potential need for PC with its entailed technical difficulty and increased operative time.
