Patients who had been receiving peridural analgesia for labour were not included, and the remaining were randomised to receiving parenteral vasopressors in case of hypotension systolic blood pressure <100mmHg, as follows: group 1, phenylephrine 100 mcg, and group, 2 ephedrine 10 mg. Maternal and neonatal outcomes were assessed but no statistical differences were found. The authors concluded that both phenylephrine as well as ephedrine, under the conditions of this trial, are eligible vasopressors for the management of hypotension in patients undergoing emergent C-section under a standardized protocol for spinal anaesthesia.
No se incluyeron pacientes que venían recibiendo analgesia peridural para el trabajo de parto y se aleatorizó a las pacientes a recibir vasopresores parenterales en caso de hipotensión presión arterial sistólica < 100 mmHg; grupo 1: fenilefrina 100 μg; grupo 2: efedrina 10 mg. Se evaluaron los desenlaces maternos y neonatales, sin que se encontraran diferencias estadísticas, y se concluye que tanto la fenilefrina como la efedrina bajo las condiciones de este estudio son vasopresores elegibles para el manejo de la hipotensión en pacientes sometidas a cesárea urgente bajo un protocolo estandarizado de anestesia espinal.
