Postdural Puncture Headache

This study will aim to investigate whether systemic inflammatory markers-especially the neutrophil-to-lymphocyte ratio (NLR)-obtained from preoperative complete blood counts can predict the development of post-dural puncture headache (PDPH) in obstetric patients undergoing cesarean section under spinal anesthesia.

The purpose of the study is to learn more about a new device, the EpiZact Epidural Device, that may be helpful for reducing the likelihood of wet tap when a labor epidural is placed. When epidurals are placed correctly the needle stops just in front of the space in the body that contains cerebrospinal fluid. When the epidural is advanced a short distance further, leakage of cerebrospinal fluid can occur. This is known as a wet tap. A wet tap can result in a severe headache and at times other complications. The goal of this clinical trial is to learn if the use of the EpiZact device prevents wet taps in pregnant women receiving epidurals for relief of labor pain. The main questions this study aims to answer are: 1. What the rate of wet tap with the EpiZact device? 2. What is the rate of failed epidural placement with the EpiZact device? All patients in the study will receive an epidural with the EpiZact device. The investigators will compare the results with patients not in the study that receive an epidural without the EpiZact device.
