Single-dose caudal anaesthesia for two infants undergoing diagnostic brain magnetic resonance imaging: high risk and nonhigh risk.
We present a case report of two infants given a bupivacaine caudal anaesthetic as a means of achieving sedation for a diagnostic brain magnetic resonance imaging (MRI). Patient 1 was born at 27 weeks of gestation and presented to our hospital at 39 weeks postconception with a history of bronchopulmonary dysplasia and apnoea/bradycardia spells. He was undergoing a brain MRI for the work up of persistent apnoea and craniofacial abnormalities. Patient 2 was a term infant at 42 weeks postconception undergoing a MRI for the work up of a seizure disorder. Both infants fell asleep shortly after placement of the caudal blocks and the studies were completed successfully without complications. Utilizing this technique, we avoided dealing with a potentially difficult airway (patient 1), exacerbating postoperative apnoea and the negative implications of intravenous sedation during a study where there is limited access to the patient's airway.
