Background and Aims: Postdural puncture headache (PDPH) is a side effect of spinal anaesthesia (SA). This study was conducted to investigate the effect of intrathecal fentanyl on the incidence, severity, and duration of PDPH. Methods: This was a prospective randomised controlled study including 220 parturients, who underwent Caesarean section (CS). They were divided into two groups for administration of SA with bupivacaine (bupivacaine group [B0], n = 111) or bupivacaine with fentanyl (bupivacaine fentanyl group [BF], n = 109). Haemodynamics, quality of anaesthesia, maternal side effects, and postoperative analgesia were noted. The neonatal Apgar score was recorded. The patients were followed up for 14 days after CS for the occurrence of PDPH, and its severity and duration. The collected data were statistically analysed, using the Statistical Package for the Social Sciences software version 25. Results: Regarding haemodynamics, heart rate increased at 5 min post-induction and blood pressure decreased at 2min post-induction in both groups. Excellent intraoperative anaesthesia was obtained in 91.7% and 79.3% of cases in groups BF and B0, respectively (P < 0.01). Longer duration of postoperative analgesia was present in the BF group as compared to the B0 group (P < 0.001). The incidence of PDPH decreased in the BF group in a non-significant manner, whereas its severity and duration increased significantly in the B0 group. Conclusion: Although the addition of intrathecal fentanyl to bupivacaine for SA in CS patients did not reduce the incidence of PDPH significantly, its severity and duration decreased significantly.
