Prospective randomized comparison of cerebrospinal fluid aspiration and conventional popping methods using 27-gauge spinal needles in patients undergoing spinal anaesthesia
BMC Anesthesiology Feb 06, 2020
Han JU, Kim BG, Yang C, et al. - Given that technical difficulty is encountered while performing spinal anaesthesia using the conventional popping method with a 27-gauge (27G) spinal needle, so, researchers compared the aspiration and conventional popping method for spinal anaesthesia utilizing 27G Quincke-type needles in this prospective, randomized study with 90 patients. The participants aged 19 to 65 years, had American Society of Anesthesiologists physical status I-III, and were receiving spinal anaesthesia. The success rate of the first attempt to perform dural puncture was considered as the primary outcome. In this study with 88 patients, the success rate of the first attempt for dural puncture was reported to be 93.3% vs 72.1% in the aspiration group vs in the popping group, respectively. A significantly higher number of attempts and significantly longer total procedure time were observed in the popping group. Findings revealed that clinical benefits for dural puncture were afforded by the aspiration method using a 27G Quincke-type needle vs the conventional popping method for spinal anaesthesia.
