AbstractThe objective of this study is to assess both intra and post operative analgesia in infants undergoing umbilical hernia repair under general anaesthesia with neither opioid nor muscle relaxant, associated with a para umbilical block. It's a prospective study covering a 15 months period. The study included 75 infants (age = 5 months - 13 years; body weith = 6 kg - 35 kg). General anaesthesia was induced with either thiopentone or halothane and, maintained with halothane in a N2O - O2 50 VOL % mixture. Para-umbilical block was obtained using 1 ml/kg of 0.25% marcaïne. Pain was assessed using time course of respiratory rate, heart rate and mean arterial pressure. A change of more than 20% in one of these variables was considered criterion of poor analgesia. Intraoperative analgesia was adequate in all patients but four, 5 minutes after incision. Surgical conditions were considered as being godd or satisfactory in 90.6% and 9.4% of cases, respectively. Post operative analgesia, assessed 1 and 6 hours after completion of surgery was convenient in 93.3% of infants. The block appears as simple, most after efficient and safe in umbilical surgery.
