Aim: To retrospectively describe the performance of ultrasound guided thoracic epidural anaesthesia under sedation for anaesthesia management of open pyloromyotomy. Background: Anaesthesia management for hypertrophic pylorus stenosis is usually performed under general anaesthesia with tracheal intubation. Only a few publications describe avoidance of tracheal intubation in infants by using spinal or caudal anaesthesia. The present retrospective analysis describes the performance of ultrasound guided thoracic epidural anaesthesia under sedation for anaesthetic management of open pyloromyotomy. Methods: Twenty consecutive infants scheduled for pyloromyotomy according to the Weber-Ramstedt technique were retrospectively analysed. After sedation with nalbuphine and propofol, an ultrasound guided single shot thoracic epidural anaesthesia was performed with 0.75 ml.kg-1 ropivacaine 0.475%. Insufficient blockade was defined as increase of HR > 15% from initial value and / or any movements at skin incision. In those cases we were prepared for rapid sequence intubation according to the departmental standard. Results: All pyloromyotomies could be performed under single shot thoracic epidural anaesthesia and sedation. One case of moderate oxygen desaturation was treated with intermittent ventilation via face mask. Conclusions: Thoracic epidural anaesthesia under sedation for pyloromyotomy has been a useful technique in this retrospective series of infants suffering from hypertrophic pylorus stenosis. In 1/20 infants short term assisted ventilation via face mask was required. Undisturbed surgery was possible in all cases.
