Peridural Bupivacaine and Morphine for Residual Pain After Peripheral Vascular Surgery
Patients displaying persistent leg pain for more than 10 days after objectively successful leg revascularisation surgery were divided into three groups receiving epidural injections of: 1. bupivacaine (10 ml/0.5%; n = 15), 2. morphine sulphate (2 mg/10 ml; n = 15) and 3. morphine sulphate (2 mg) + bupivacaine (10 ml/0.25%; n = 17). Group 1 showed good analgesia and a significant incidence of hypotension (-20-40 mmHg; n = 6), skeletal muscle hypotonia (n = 7), bradycardia (n = 3) and urinary retention (n = 4). Group 2 showed a poorer analgesic response and no significant effect on other measures. Group 3 patients showed an analgesia comparable to that of group 1, with no effect on cardiovascular measures, but produced urinary retention (n = 3).
