Evaluation of 25-gauge Quincke and 24-gauge Gertie Marx needles for spinal anaesthesia for caesarean section . OBJECTIVE To compare the insertion characteristics and rate of complications between 25-gauge Quincke and 24-gauge Gertie Marx needles . DESIGN Prospective , randomized study . SETTING University of Benin Teaching Hospital ; a university-affiliated tertiary centre . SUBJECTS Parturients ( ASA 1 and 2 ) scheduled for elective caesarean section . They were randomly assigned to receive spinal anaesthesia with either 25-gauge Quincke needle or 24-gauge Gertie Marx needle . The patients with abnormal spaces , coagulopathy , infection , pre-eclampsia/eclampsia or obesity were excluded . MAIN OUTCOME MEASURES The number of attempts at successful identification of the spinal space , intraoperative complications , incidence of postdural puncture headache ( PDPH ) , non-postdural puncture headache ( NPDPH ) and backache . RESULTS Sixty women were studied . The 24-gauge Gertie Marx needle resulted in more successful location of the spinal space on the second attempt ( P < 0.05 ) . Non-postdural puncture headache was seen in 43 % of the study population . PDPH was seen in 10 % of the Quincke group and none in the Gertie Marx group . There was no difference in the incidence of backache in both groups . CONCLUSION The ease of insertion and low incidence of PDPH with the Gertie Marx needle may encourage trainee anaesthetists to use this needle for caesarean section .
