ABSTRACT
BACKGROUND:
Use 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 of short-duration paediatric laparoscopic surgery using this anaesthetic technique. We assessed surgical conditions for paediatric laparoscopic inguinal hernia repair using P-LMA with and without neuromuscular block.METHODS:
Sixty-six patients undergoing laparoscopic inguinal hernia repair were randomised to receive a neuromuscular block (train-of-four 1-2 twitches) using rocuronium or no neuromuscular block with the P-LMA. All operations were performed by the same surgeon who determined the surgical conditions using the Leiden-surgical rating scale (L-SRS). Secondary outcomes included perioperative data, haemodynamics, and adverse events.RESULTS:
Neuromuscular block improved surgical conditions compared with no neuromuscular block mean (standard deviation) L-SRS 4.1 (0.5) vs 3.5 (0.6), respectively (P<0.0001). Mean rocuronium dose in the neuromuscular block group was 12.7 (4.4-29.7) mg or 0.7 (0.6-0.8) mg kg-1. The insufflation Ppeak was higher in the no neuromuscular block group than in the neuromuscular block group mean (standard deviation) Ppeak 17.9 (1.8) cm H2O vs 16.2 (1.9) cm H2O, respectively (P=0.0004). Fifteen children (45.5%) in the no neuromuscular block group had adverse events during the surgery and anaesthesia vs four children (12.1%) in the neuromuscular block group (P=0.006).CONCLUSIONS:
Neuromuscular block significantly improved surgical conditions and reduced the incidence of adverse events during surgery and anaesthesia when an LMA Proseal™ was used in short-duration paediatric laparoscopic surgery. CLINICAL TRIAL REGISTRATION ChiCTR2000038529.Palavras-chave
