Effect of Intrathecal Injection Speed on Post-Dural Puncture Headache in Parturients Undergoing Cesarean Section: A Prospective, Randomized Study

Aim: In this study, it was aimed to evaluate the effect of intrathecal injection rate on post- dural puncture headache (PDPH) in cesarean patients. Material and Methods: 140 patients between 18-45 years of age who were scheduled for caesarean section with spinal anesthesia were randomly divided into two groups. From the L4-L5 level in the sitting position, 10 mg hyperbaric 0.5% bupivacaine with a 25 G Quincke spinal needle, median inlet; Intrathecal injection was performed as quickly as possible in the patients in Group I and administered to patients in Group II by intrathecal injection in 40 seconds. Hemodynamic data, ephedrine use and frequency of nausea and vomiting were recorded intraoperatively. 7 days after the procedure, the patients were called by phone and questioned for PDPH. The ICHD-III criteria were used to question the PDPH. Results: There was no significant difference in the incidence of postdural headache (Group I: 29.0% and Group II: 31.4%) and severity (p> 0.05). There was no significant difference between the groups when haemodynamic data, ephedrine usage, nausea and vomiting frequency were compared (p> 0.05). Conclusion: In the cases of cesarean section with spinal anesthesia, hyperbaric bupivacaine is given to the intrathecal area at different rates; We conclude that PDPH frequency and severity do not affect haemodynamic parameters, ephedrine requirement and frequency of nausea and vomiting
