Using Optic Nerve and Brain Oxygen Measurements to Predict Postdural Puncture Headache in Women Having Elective Cesarean with Spinal Anesthesia

What this Trial Is About

This research aims to predict the development of postdural puncture headache PDPH in pregnant women undergoing elective cesarean delivery with spinal anesthesia. PDPH is a common complication caused by cerebrospinal fluid leakage after dural puncture, leading to symptoms like headache, neck stiffness, and photophobia. The study explores changes in the optic nerve sheath diameter ONSD and cerebral oxygen levels as potential early indicators for PDPH, which could improve recovery and care for mothers and newborns. Participants are monitored for changes in ONSD at several time points before spinal anesthesia, 10 minutes after, at the end of surgery, and 24 hours postoperatively. The study also evaluates cerebral oxygen saturation during surgery using near-infrared spectroscopy NIRS. Patients are grouped based on whether they develop PDPH within five days after surgery, with assessments conducted in hospital rooms or via daily phone follow-ups. During the study, participants undergo clinical evaluations to track headache development and cerebral oxygenation changes. Outcomes measured include perioperative ONSD changes, cerebral oxygenation during surgery, and the incidence of post-spinal hypotension. Monitoring occurs throughout the perioperative and immediate postoperative periods, with the total study participation lasting up to five days post-surgery to assess PDPH occurrence and related physiological changes.
