title: [A comparison of maternal and fetal complications during operative vaginal delivery using Thierry's spatulas and the vacuum extractor].
abstract: OBJECTIVE
  To compare short-term maternal and fetal morbidities between Thierry's spatules and the vacuum extractor.
  
  
  METHODS
  A retrospective study of all assisted vaginal deliveries using spatules or the vacuum extractor between January 1, 2005 and December 31, 2007 in a single, university hospital maternity.
  
  
  RESULTS
  There were 385 deliveries with the vacuum extractor and 332 with spatulas, among a total number of 6941 deliveries. The obstetrical conditions did not differ between the two groups (indication, level or type of presentation, duration of the second stage before extraction). The rate of episiotomy was higher in the spatules than in the vacuum extractor group (80.3 % vs 54.8 %, p < 0.0001), whereas there was a lower rate of first-to-second degree perineal lacerations (18.8 % vs 35.2 %, p < 0.0001). There was no statistically significant difference in the rate of third-to-fourth degree perineal lacerations (2.1 % vs 0.7 %, respectively, p = 0.31). Neonatal outcomes did not differ significantly between the two groups (5-minute Apgar score < 7 in 0.3 % vs 1.8 %, respectively, p = 0.75).
  
  
  CONCLUSIONS
  There were few differences in maternal and neonatal outcomes according to the type of instrument used, except for a lower episiotomy rate with vacuum extraction.
