Incidência e fatores associados à cefaléia pós-punção dural em pacientes submetidos à raquianestesia

by Amorim, Jane Auxiliadora

Abstract (Summary)
This study aims to evaluate the incidence and associated factors of postdural puncture headache in 640 (332 female) patients (8?65 years of age), submitted to spinal anesthesia with needles Quincke 25G or 27G, in the period one year. Forty-eight (7.5%) of the patients developed PDPH. The binary logistic regression analysis identified as associated factors for PDPH: gender [11.1% female vs 3.6% male OR 3.39 (1.70?6.77); plt;0.01], previous history of PDPH [26.4% positive vs 6.2% negative OR 5.84 (2.90?11.79); plt;0.01], needle caliber [10.9% 25G vs 5.5% 27G OR 2.10 (1.16?3.80); p=0.01], direction of the needle bevel [16.1% perpendicular vs 5.7% parallel OR 3.18 (1.70?5.94); plt;0.01]. The odds ratio adjusted by multivariate regression was [2.28 (1.09?4.80); p=0.03] to gender, [4.23 (1.99?8.99); plt;0,01] to previous history of PDPH, [1.49 (0.77?2.89); p=0,24] to needle caliber and [2.16 (1.07? 4.37); p=0.03] to direction of the needle bevel. Did not represent associated factors for PDPH: age, previous history of headache, angle of the needle insertion, number puncture of attempt and type of surgery. The associated factors of PDPH in this study were: gender, previous history of PDPH and direction of the needle bevel
