Spinal or general anaesthesia for surgery of the fractured hip? A prospective study of mortality in 578 patients

Abstract

The mortality following surgical correction of upper femoral fractures was investigated in 578 patients, over the age of 50 yr, randomly allocated to receive spinal (bupivacaine) or general (enflurane or neurolept) anaesthesia. Thirty days after surgery the mortality was 6% after spinal and 8% after general anaesthesia (ns). Six months to 2 years after surgery the mortality was identical in the two groups. There were no differences with respect to ambulation and discharge. The estimated blood loss was smaller (P less than 0.05) in patients receiving spinal anaesthesia. Regardless of the anaesthetic technique, a high short-term mortality was related to age, male sex, and trochanteric fracture, whereas excess long-term mortality was related to male sex and high ASA scores.
