BACKGROUND: During cesarean delivery, extracting a deeply impacted head is a real challenge for obstetricians.
OBJECTIVES: To compare selected maternal and fetal outcome indicators of the "pull" (reverse breech extraction) and "push" methods for impacted fetal head extraction during cesarean delivery.
SEARCH STRATEGY: A computer-based search of the Medline, Cochrane library, and HINARI databases.
SELECTION CRITERIA: Studies that compared the maternal and perinatal outcomes of the push and pull methods for impacted fetal head extraction during cesarean delivery were included.
DATA COLLECTION AND ANALYSIS: A meta-analysis of Mantel-Haenszel odds ratios and standardized mean differences from 11 randomized comparative and retrospective cohort studies was performed.
MAIN RESULTS: In the pooled analysis, the risk of uterine incision extension was more than 8 times higher with the push method than with the pull method. Blood loss and operation time were also increased with the push method, and this method was associated with more perinatal deaths and admissions to the neonatal intensive care unit. The risk of wound infection was not significantly different between the 2 methods.
CONCLUSIONS: The present meta-analysis demonstrated marked reductions in uterine incision extension, blood loss, and operation time with reverse breech extraction.
