A mechanical hand grip dynamometer was used to derive age- and sex-related standard grip strengths from 247 healthy volunteers between 16 and 95 yr old. Preoperative grip strength was measured in 90 patients and related to postoperative complication rates. A grip strength of 85% standard for age and sex was found to be the most effective cut-off for prediction of postoperative complications in terms of sensitivity and specificity, predicting 74% of the complications (p less than 0.05). Specificity is improved over previously published standards related to sex alone especially when assessing the elderly patient (50% vs 21%). A grip strength below the recommended cut-off for age and sex suggests that the patient is in a high-risk group and demands further investigation of nutritional status. Studies of pre-operative nutritional support for the at risk group need to be undertaken.
使用机械握力计从247名年龄在16至95岁之间的健康志愿者中得出与年龄和性别相关的标准握力。对90例患者术前握力进行测量，并与术后并发症发生率相关联。发现年龄和性别标准握力的85%是预测术后并发症在敏感性和特异性方面最有效的临界值，可预测74%的并发症（p<0.05）。与仅与性别相关的先前公布的标准相比，特异性有所提高，尤其是在评估老年患者时（50%对21%）。低于年龄和性别推荐临界值的握力表明患者处于高危组，需要进一步调查营养状况。需要对高危组进行术前营养支持研究。
