A 3411–1 lumbar plexus block with the aid of a nerve stimulator was performed in 32 patients and a psoas compartment block was performed in five patients for muscle biopsy of the upper leg for diagnosis of malignant hyperthermia (MH) susceptibility. Twenty‐two patients were found to be MH susceptible by the in vitro contracture test. Twenty patients received 40 ml prilocaine 1.5% with epinephrine 1:2 and two received 40 ml bupivacaine 0.5% with epinephrine 1:2 without any untoward reaction. The 3‐in‐1 block provides a high success rate and excellent analgesia for muscle biopsy of the upper leg. Amide local anaesthetics are safe in MH‐susceptible patients.
