Delayed recovery of hand grip strength predicts postoperative morbidity following major vascular surgery.
Forearm muscle dynamometry was performed in the non-dominant arm in 61 patients undergoing major abdominal and limb vascular surgery, before operation and then 1, 3, 5, and 7 days after surgery. Six patients died in the postoperative period and seven patients developed major postoperative complications (bronchopneumonia, two; wound infection, four; myocardial infarction, one). The preoperative grip strength, measured in kilograms, of the patients who died after major vascular surgery was not significantly lower than that of patients who had an uncomplicated postoperative course. Of the 55 surviving patients, seven developed complications after surgery. These patients had significantly reduced grip strength, expressed as a percentage of the individual preoperative value (P less than 0.05), from the first to the seventh postoperative day when compared with patients without complications. The delayed recovery of grip strength preceded the clinical manifestation of complications. These data suggest that delayed recovery of voluntary muscle performance may be used to detect patients developing postoperative complications and so allow their early treatment.
