When patients were scheduled for emergent C-section categories 2-3 NICE, they were randomised to two groups for anaesthesia extension using peridural catheter, as follows: group 1, lidocaine-bicarbonate-adrenaline at final concentrations of 1.8%, 0.76% and 1:200,000, respectively, for a total volume of 20.1 cc; and group 2, 20 cc of 0.5% levobupivacaine no peridural fentanyl was used in either group.
La latencia se acortó de manera significativa en el grupo 1 lidocaína, bicarbonato- adrenalina.
