Summary We have studied the acid‐base equilibrium in 12 patients with end‐stage renal failure (ESRF) during capno‐retroperitoneoscopic nephrectomy. Bupivacaine (12 mL, 0.375%) and morphine (2 mg) were given in the lumbar epidural space, and fentanyl (0.5 µg kg −1 ) and midazolam (50 µg kg −1 ) were given intravenously. Anaesthesia was induced by thiopental, maintained with halothane carried by oxygen enriched air (inspired oxygen fraction = 0.35), and ventilation was achieved with a tidal volume of 10 mL kg −1 at a rate of 12 min −1 . This procedure resulted in a mild degree of respiratory acidosis that was cleared within 60 min. We conclude that capnoretroperitoneoscopic nephrectomy can be performed in patients with end‐stage renal failure with minimal transient respiratory acidosis that can be avoided by increased ventilation.
