In brief
Retrospective study of 168 infants undergoing laparoscopic pyloromyotomy comparing three anesthesia induction approaches: classic RSI with succinylcholine, modified RSI with cisatracurium, or no neuromuscular blocking agent. No significant differences in extubation time or complication rates were found, supporting modified RSI as safe and effective for this population.

Introduction Infants with hypertrophic pyloric stenosis have gastric outlet obstruction, indicating a pyloromyotomy. To prevent aspiration, a rapid sequence induction (RSI) of anesthesia used to be preferred. However, due to concerns about the side-effects of this technique in infants, a modified RSI with gentle mask ventilation is nowadays mostly used. This research investigates if induction with succinylcholine (classic RSI), cisatracurium (modified RSI), or no neuromuscular blocking agent (NMBA) influences time until extubation and incidence of complications in infants undergoing laparoscopic pyloromyotomy.
Materials and Methods A retrospective chart review was performed, observing infants undergoing laparoscopic pyloromyotomy in Erasmus Medical Centre-Sophia Children's Hospital, Rotterdam, from January 2007 until July 2015. Baseline preoperative data, anesthesia and operation details, time to extubation, and reported complications were gathered. Inclusion criteria were maintenance of anesthesia with sevoflurane and a registered extubation time. Exclusion criteria were the use of combinations of NMBAs, repyloromyotomy, and conversion to laparotomy.
Results A total of 168 patients were included, of which 21 received succinylcholine, 107 cisatracurium, and 40 no NMBA. Mean duration of surgery was 29 minutes in all three groups; mean duration of anesthesia was 89, 82, and 77 minutes; mean time to extubation was 26, 25, and 23 minutes, respectively, without statistically significant difference. Complications were evenly distributed, no aspiration occurred.
Conclusion The use of succinylcholine, cisatracurium, or no NMBA at induction of anesthesia in infants undergoing laparoscopic pyloromyotomy had no statistically significant effect on time until extubation and complication rates. A modified RSI seems to be safe and effective in these cases.
