Abstract

OBJECTIVE: Our goal was to determine the effect of shoulder dystocia on umbilical artery acidosis. STUDY DESIGN: We performed a retrospective analysis of 134 mother-infant pairs of shoulder dystocia cases at our institution from January 1, 1994, through December 31, 1997. Cases were identified from the obstetric database,and charts were abstracted for demographics, head-to-body delivery interval, umbilical blood gas parameters, and neonatal outcome. Pooled student t tests were used to compare mean blood gas values with data previously reported from our patient population. Regression analysis was performed regardinghead-to-body delivery interval and blood gas parameters. RESULTS: The mean umbilical artery pH of shoulder dystocia cases (7.23 +/-.082) was less than the mean arterial pH of all vaginal deliveries in our institution (7.27 +/- .069), P < .001. Head-to-body delivery intervals (available for 44 cases) were not associated with statistically significant alterations in umbilical artery pH (r(2)=.0004), P-CO2 (r(2)=.011), or base deficit (r(2)=.006). Increasing head-to-body delivery interval was also not significantly correlated with decreasing 5-minute Apgar score (r=.0278). CONCLUSION: In our study population, shoulder dystocia resulted in statistically significant but clinically insignificant reductions in mean umbilical artery blood gas parameters. No statistically significant linear relationship was identified between the head-to-body delivery interval and fetal acid-base status.
