Risk factors of post-dural puncture headache receiving a blood patch in @entity2143 XXXX .

@entity1 @entity2143 @entity1337 @entity9737
BACKGROUND: @entity9737 ( @entity9737 ) is one of the most frequent complications of neuraxial anesthesia and @entity1337 . The objective is to determine risk factors of @entity9737 receiving a blood patch in the @entity2143 population. METHODS: Between November 2009 and January 2013, 10914 @entity1 delivered in Port Royal maternity unit (Paris, France). The incidence of @entity9737 receiving a blood patch was calculated among those who received neuraxial @entity1337 or anesthesia for delivery. Then we performed a case-control study to identify risk factors for @entity9737 receiving a blood patch by comparing @entity1 who experienced @entity9737 receiving a blood patch with some @entity1 randomly selected by computer among those who delivered during the study period (4 controls for 1 case, univariate and multivariate analysis). RESULTS: Among the 10685 @entity1 who had neuraxial @entity1337 or anesthesia, 0.4% had a @entity9737 receiving a blood patch. In the univariate analysis, cervix dilatation >= 7 cm, lateral decubitus position during the neuraxial procedure and multiple punctures were significantly associated with @entity9737 receiving a blood patch, whereas maternal Body Mass Index, age, mode of delivery, performance at night and level of needle insertion were not. In the multivariate analysis, cervix dilatation >= 7 cm and multiple punctures significantly increased the risk of @entity9737 receiving a blood patch (odd ratios 6.5 [95% CI: 1.5-29.3] and 5.6 [95% CI: 2.2-14.0], respectively). Experience of the anesthesiologist was not associated with @entity9737 in both univariate and multivariate analysis. CONCLUSIONS: In the @entity2143 population, a cervix dilation >= 7 cm during labor and multiple punctures are independent risk factors for @entity9737 receiving a blood patch.
