Background: Continuous spinal anaesthesia during Caesarean delivery has been found to offer considerable advantages over "single-shot" spinal. Aim: This study aimed to find the difference between priming and non-priming of the Wik-Wire extension set with local anaesthetic on the induction-incision interval. Methods: Thirty ASA I and II parturients aged between 21 and 38 years scheduled for elective repeat Caesarean section were randomly allocated into one of two groups of 15 patients each. Patients in Group A had the Wik-Wire extension set primed with 1 ml of isobaric bupivacaine and threaded through flexible cannula. On connection with the hub of the cannula, back flow of cerebrospinal fluid (CSF) was confirmed by a drop hanging at the hub of the set. Group 2 patients had the un-primed Wik-Wire extension set connected to the flexible cannula. On connection with the hub of the cannula, back flow of CSF was evidenced by lowering the extension set to fill the tubing until the proximal cap of extension set was fully primed with passive flow of CSF. Isobaric 0.5% bupivacaine 10 mg was then administered intrathecally as the parturients returned supine while ensuring 15o left uterine displacement. Induction to delivery interval (I-D), defined as time from institution of induction of regional anaesthesia to delivery was studied. Results: All patients had satisfactory anaesthesia. The mean induction to incision (I-I) interval in group A 3.8 ± 1.5 mins while this was 7.2 ± 2.2 mins in group B, p=0.001. One patient in group B required a single dose of 5 mg ephedrine; while none required vasopressor support in group B. Conclusions: The study concludes that a primed Wik-Wire extension set can significantly reduce the induction of continuous spinal anaesthesia to delivery interval provides a fast and effective anaesthesia for caesarean section.
