Effect of neuromuscular block on surgical conditions during short-duration paediatric laparoscopic surgery involving a supraglottic airway

BackgroundUse of an LMA ProSeal™ laryngeal mask airway (P-LMA; Teleflex) with no neuromuscular block is considered a safe alternative to tracheal intubation in short-duration paediatric laparoscopic surgery. However, few studies have evaluated surgical conditions surgery using this anaesthetic technique. We assessed for inguinal hernia repair P-LMA and without block.MethodsSixty-six patients undergoing were randomised receive (train-of-four 1–2 twitches) rocuronium or the P-LMA. All operations performed by same surgeon who determined Leiden-surgical rating scale (L-SRS). Secondary outcomes included perioperative data, haemodynamics, adverse events.ResultsNeuromuscular improved compared block: mean (standard deviation) L-SRS 4.1 (0.5) vs 3.5 (0.6), respectively (P<0.0001). Mean dose group was 12.7 (4.4–29.7) mg 0.7 (0.6–0.8) kg−1. The insufflation Ppeak higher than group: 17.9 (1.8) cm H2O 16.2 (1.9) H2O, (P=0.0004). Fifteen children (45.5%) had events during anaesthesia four (12.1%) (P=0.006).ConclusionsNeuromuscular significantly reduced incidence when Proseal™ used surgery.Clinical trial registrationChiCTR2000038529.
