Abstract
BACKGROUND: The time from birth to the first paediatric surgical consultation of neonates with gastroschisis is a predictor of mortality in dveloping countries. This is contrary to findings in the developed world. We set out to document this relationship within our population. METHOD: Neonates with gastroschisis who were transferred to Steve Biko Academic Hospital within the study period were included. The association between mortality and demographic, clinical and biochemical variables was assessed. Significant variables after univariate analysis were subjected to multivariates regression. RESULTS: Sixty patients were included. The mortality rate was 65%. Mean transfer time and distance were 14.9 hours and 225km. Forty-eight per cent of the neonates were either dehydrated or in hypovolaemic shock clinically on arrival. Eight neonates arrived hypothermic. It was shown through univariate analysis that female sex, appropriate weight for gestational age, hydration status, gestation, transfer time, serum urea, base deficit and serum bicarbonate (HCO3) were significant predictors of mortality. Only female sex, appropriate weight for gestational age and serum HC03 were shown to be significant using ultivariate analysis. CONCLUSION: Our high mortality rate was not due to lengthy transfer times. The poor clinical condition of the patients on arrival at our hospital, which relates to deficiencies in the neonatal transfer system, had a direct impact on the survival of neonates with gastroschisis.
