ABSTRACT
Awake thoracic epidural anaesthesia as the sole anaesthetic technique was successfully employed for two high risk surgical patients with chronic obstructive pulmonary disease undergoing abdominal surgery. The procedure was tolerated well and the anaesthetic technique which has been shown to reduce intra-operative and post-operative cardiac, respiratory and gastrointestinal complications, may have significantly contributed to the prompt, complication free recovery experienced by both patients. We report two cases of awake major abdominal surgery in two high-risk surgical patients with severe pulmonary disease, performed effectively under thoracic epidural anaesthesia as a sole technique. The first case was an elective open sigmoid colectomy in a sixty one year old cancerous patient with chronic obstructive pulmonary disease [COPD] and recent thoracotomy for a wedge resection of a bronchial adenocarcinoma [pT1NoMx]. The second case was an emergency open cholecystectomy in an adult patient with end-stage COPD. Reviewing the literature, no similar cases were reported recently.

Thoracic epidural analgesia appears to improve the outcome of patients undergoing coronary artery bypass graft surgery. Cranial extension of nerve blockade involving the third, fourth and fifth cervical nerve roots can cause apnoea. However, progressive paraesthesia and weakness due to cephalad spread of thoracic epidural analgesia will affect the arms before the diaphragm. A scale was designed to test three active movements of the arms bilaterally: hand grip (T1/C8), wrist flexion (C8/7) and elbow flexion (C6/5). This epidural scoring scale for arm movements (ESSAM) consists of four grades (0-3) based on the number of absent movements, and suggests appropriate action. The reliability of this scale was tested in 40 patients undergoing coronary artery bypass surgery. Twelve of the 40 patients had their epidural infusion reduced on the basis of the scale. Of these 12 patients, eight had a worst ESSAM score of 1, three had a worst score of 2 and one had a worst score of 3. In each patient, motor power returned following the reduction in infusion rate, taking between 30 min and 3 h. This scale appears to be a simple and reliable method for the early detection of the cephalad spread of thoracic epidural analgesia.
