Background and Aims:The fascia iliaca compartment block (FICB) is commonly administered in children for anterolateral thigh surgery. The actual spread of the local anaesthetic (LA) beneath the fascial layers in children is not known. We hypothesised that in children there could be a possibility of the LA to reach lumbar plexus with the dose we used.Methods:This study included 25 children, aged 1-15 years for lower limb surgeries after standardised general anesthesia, the FICB was done with ultrasonography. Radio-opaque dye was tagged to LA and the fluoroscopic study was performed. The catheter was placed under ultrasonography. The primary objective was to investigate the fluoroscopic demonstration of the extent of LA spread by our technique and drug volume which is not known in children. The secondary objectives were to evaluate the intraoperative and postoperative analgesic efficacy, complications if any, of the continuous FICB catheters placed by our method.Results:In all patients, the visualisation of ilium and iliacus muscle, the fascia iliaca and needle tip was possible. The fluoroscopic imaging showed that the LA did not spread till the lumbar plexus in 20 patients. In 5 patients, delineated the psoas muscle and reached the L4 vertebral level. The analgesia was adequate. In the postoperative period, 92% had sufficient pain relief. Mild soakage was an issue with catheters.Conclusion:Although single shot fascia iliaca compartment block has limited spread of local anaesthetic in children, it is efficacious. Continuous fascia iliaca compartment block is feasible and effective in this age group.

Ultrasound guidance aids in identification of normal intervertebral space and explicitly shows the abnormal space. It can be used as an aid to differentiate between normal and abnormal space in post-meningomyelocele repair.

Background and Aims: Current concerns related to the anesthetic neurotoxicity have brought a renewed interest in regional anesthesia. Regional anesthesia reduces the need for opioids and inhalational anesthetics. The immaturity of the neonatal and infant nervous system may render them more prone to neurotoxicity. We describe our technique of anesthesia, which minimizes the exposure to general anesthetics and reduces airway instrumentation because the operability is rendered by the regional block. Material and Methods: This was a retrospective case series of neonates and infants undergoing common surface surgeries. We describe our technique of anesthesia where regional blocks are the mainstay. We also put up the data pertaining to block effectiveness, technique, end-tidal sevoflurane concentration and complications. Results: One thousand patients, including neonates and infants, received central and peripheral nerve blockade. The failure rate in upper extremity blocks 0% without complications. 86.12% were given under ultrasonography (USG) guidance and 13.89% were given with peripheral nerve stimulation. The failure rate of sciatic block single shot and continuous was 0%. 92.53% were given with USG guidance while 7.46% received sciatic with nerve stimulation technique. Failure rate of caudal epidural block was 0. 78% requiring a rescue analgesic, 1.4% had blood in the needle. Out of the caudals, 33.33% were done with USG guidance and 66.67% blocks were given with traditional techniques. Out of the 322 penile + ring blocks given by traditional method, 1 block failed requiring rescue analgesics. The mean sevoflurane concentration was 1.2 +/- 0.32. Conclusion: It is feasible to conduct surface surgeries in the most vulnerable population such as neonates and infants under regional anesthesia without intubation and airway instrumentation.
