Factors that influence the appearance of dural post-puncture headache in patients undergoing elective cesarean section.

Abstract

An epidemiological, observational, analytical and retrospective study of cases and controls was conducted with women undergoing elective cesarean section under spinal anesthesia at the Carlos Manuel de Cespedes Hospital in Bayamo, Granma province, from February 2013 to December 2015; with the objective of identifying the risk factors hypothetically related to the appearance of postpuncture dural headache in obstetric patients undergoing elective cesarean section. All the patients who gave their consent to participate, their data collection form was prepared for the study that collected the variables of the study. In addition, with each hypothetically influencing factor, the estimate of the benefit frame (OR) and its 95% confidence intervals (95% CI) and the hypothesis test of Chi to Square were performed. The age less than 25 years, the history of previous headache, the diameter of the needle of 20 and 22G, the greater number of puncture attempts and the position of the seated patient are the risk factors related to the appearance of post-puncture headache dural, but not the body mass index higher than 30 in obstetric patients undergoing elective cesarean section.
