Ex-premature infants, before 45 weeks postconceptional age, are at high-risk of apnoea after surgery. General anaesthesia increases the risk of apnoea. We evaluated the tolerance and the efficiency of caudal anaesthesia performed in 25 consecutive conscious ex-premature infants for inguinal herniotomies. N2O/O2 and EMLA cream are used to facilitate caudal puncture. Anaesthesia procedure, patient comfort and complications following the 24 postoperative hours were studied. We report good anaesthesia conditions without compromising the baby’s comfort and few perioperative complications. Only two infants with a prior history of apnoea or bronchopulmonary dysplasia had apnoea during and after surgery. A total spinal anaesthesia was the major complication in one infant and prolonged surgery requiring general anaesthesia was the main limitation of this technique in another child. The principal advantage of the procedure is to facilitate and simplify the postoperative management of the babies. The anaesthetic technique does not alter surgical conditions. Caudal epidural anaesthesia performed in awake high-risk preterm infants is beneficial for these infants but requires experienced operators. [ABSTRACT FROM AUTHOR]
