Randomized Controlled Trial Clinical Trial
Perioperative myocardial ischaemia in patients undergoing surgery for fractured hip randomized to incremental spinal, single-dose spinal or general anaesthesia.
Quantitative assessment of myocardial ischaemia during incremental spinal, single-dose spinal and general anaesthesia may provide guidelines for the choice of anaesthetic technique for osteosynthesis of hip fractures in the elderly atherosclerotic individual. Forty-three patients with coronary artery disease were allocated to receive either incremental spinal anaesthesia (bupivacaine 0.5% plain) (A), single-dose spinal anaesthesia (2.5 mL of bupivacaine 0.5% plain) (B) or general anaesthesia (fentanyl, thiopentone, atracurium, enflurane, N2O/O2) (C) for hip surgery. ST segment monitoring was performed from the induction of anaesthesia and for the following 48 h, and perioperative hypotension, blood loss and fluid therapy were recorded. ⋯ In (A), 1.6 mL of 0.5% bupivacaine were used as opposed to the fixed 2.5 mL dose in (B) (P < 0.001). In the first post-operative week, mortality was higher in (B) (P < 0.05) but, after 1 month, there was no significant difference in mortality between the three groups. The incidence of hypotension and myocardial ischaemia was lowest in the group receiving incremental spinal anaesthesia.
