ABSTRACT Background: This study aimed to compare the incidence of side effects after spinal anaesthesia using 25 G and 23 G Quincke spinal needles in elective lower abdominal and perineal surgeries. The research focused on various factors such as sensory and motor blockade times, hemodynamic stability, adverse effects, and the number of attempts required for successful subarachnoid block to determine the comparative impacts of both needle gauges. Methods: Sixty patients aged 40-60 years, classified as ASA grade I and II, were randomly assigned to two groups of 30. Group I received intrathecal injection with a 25 G Quincke spinal needle, and Group II received the same with a 23 G Quincke needle. Parameters such as demographic data, surgery duration, hemodynamic, sensory and motor blockade times, number of attempts for subarachnoid block, and postoperative complications were recorded and analysed. Results: The incidence of PDPH was significantly higher in the 23G group, with six cases on the third postoperative day compared to one case in the 25G group (p = 0.027). Motor blockade was more profound with the 23G needle, achieving Bromage Grade 3 in 88% of cases compared to 68% in the 25G group (p = 0.032). However, the 25G needle demonstrated better hemodynamic stability and a lower complication rate.
