Observational Study
Ultrasound-guided caudal blockade and sedation for paediatric surgery: a retrospective cohort study.
Data on safety and success rates of ultrasound-guided caudal blockade, performed on sedated children with an uninstrumented airway, are scarce. We performed a retrospective observational study of validated data from April 2014 to December 2020 in a paediatric cohort where the initial plan for anaesthetic management was sedation and caudal epidural without general anaesthesia or airway instrumentation. We examined success rates of this approach and rates of block failure and block-related complications. ⋯ Ultrasound-guided caudal epidural, performed under sedation with an uninstrumented airway, is an effective technique in the daily clinical routine. Higher body weight and mid-abdominal surgical procedures are risk factors for pain-related block failure. Patients who, regardless of chronological age, had been born as extreme preterm babies are at the highest risk for respiratory events.
