| Objective The aim of this study was to evaluate the efficacy of prophylactic pregabalin on postdural puncture headache incidence and severity after spinal anesthesia. Method 86 ASA I-II male and female patients age 20–50 years old, undergoing elective general surgeries below the umbilicus under spinal anesthesia with 3 ml heavy bupivacaine 0.5% (15 mg), patients were randomly allocated into one of two groups (Group C, = 43) (control group) received a placebo capsule 2 h preoperatively (Group P, = 43) received 150 mg pregabalin capsule 2 h preoperatively, number of attempts for spinal block, sensory level, motor block grade, postoperative time to first analgesic requirement, the incidence, onset and intensity of PDPH and adverse events were recorded for 72 h. Results The peak sensory level in C group and P group showed no statistical significant difference, the time to peak sensory block was significantly earlier in P group than group C, the time to reach the modified Bromage motor block grade 3 was significantly earlier in P group than C group, time to two segment regression of sensory level to S1 and motor block regression to modified Bromage grade 0 were statistically insignificant between the studied groups. Group P had a significantly longer time to first analgesic requirements than group C, and there was no significant difference in VAS (visual analogue scale) of pain between the studied groups. There was significant increase in sedation score in P group compared to C group at 2 h and 6 h postoperatively, and there was statistically significant reduction in the incidence rate and severity of PDPH in P group compared to group C. There were no recorded cases of dizziness, visual disturbances, or PONV. Conclusions preoperative oral pregabalin 150 mg reduced the incidence and severity of PDPH, beside the earlier onset of peak sensory and motor block with increase duration of analgesia in patients undergoing elective surgeries under spinal anesthesia. | ||||
