[Correspondence] The GAS trial
The ongoing GAS trial compares cognitive outcomes in infants randomly assigned to receive either awake-regional anaesthesia or sevoflurane-based general anaesthesia during hernia repair. The primary outcome is cognitive performance, measured at 5 years of age. The preliminary report1 described the secondary outcome of cognitive performance at 2 years of age, based on a sample of 532 patients. The average duration of anaesthesia was 54 min. At 2 years of age, equivalent cognitive scores were observed in the two groups.
