Spatula-assisted deliveries: a large cohort of 1065 cases.

OBJECTIVE

To analyze neonatal and maternal complications of operative vaginal delivery using spatulas.

STUDY

DESIGN

We conducted a retrospective observational study of 1065 consecutive spatula-assisted deliveries at Nice University Hospital from 2003 through 2006, excluding stillbirths and breech deliveries. After univariate analysis, we performed logistic regression analysis to assess risk factors for severe perineal injuries and vaginal lacerations.

RESULTS

The success rate was 98.2%. Vaginal tears occurred in 23.7% of patients. The rate of third and fourth degree perineal injuries was 6.2%. No severe neonatal complication directly related to extraction was noted. Nulliparity, shoulder dystocia and absence of episiotomy were independently associated with an elevated risk of anal sphincter damage. Nulliparity and absence of episiotomy were significantly and independently associated with an increased incidence of vaginal tears.

CONCLUSION

Rates of perineal injuries, failure and neonatal complications observed with spatulas were similar to those reported in the literature with other instruments for operative vaginal delivery.
