Trifa M, et al. - Given that spinal anaesthesia (SA) is being increasingly used in infants to avoid the potential negative neurocognitive effects of general anaesthesia (GA) and has been reported to provide a relatively short duration of surgical anesthesia, experts in the present study evaluated the duration of surgical anaesthesia of SA. Procedures included male genital, groin and multiple site surgeries. Findings suggested a high success rate of SA and it could offer an alternative to GA in children undergoing appropriate surgery expected to last as long as 60–100 min. The failure rarely occurred due to the duration of surgery.
