Investigate whether the right adductor pollicis muscle thickness is a reliable method to evaluate the nutritional status of surgical patients and whether it correlates or not correlate to other anthropometric, biochemical, and clinical parameters.
Cross-sectional study evaluating 87 patients candidates to major operations of the gastrointestinal tract. All were submitted to global subjective evaluation, traditional anthropometry (arm circumpherence ; triceps skin fold; and arm muscle circumpherence, serum albumin, lymphocytes and measurement of in both hands.
The mean right adductor pollicis muscle thickness in dominant hand was 12,64 +/- 3,19 mm and in non-dominant hand (EMAPND) 12,23 +/- 2,9 mm. Sensitivity was 72,37% for left adductor pollicis muscle and 77,33% for left adductor pollicis muscle thickness being the cut-offs given by the ROC curve (13,4 and 13,1mm respectively). Specificity was 100% for both hands. There was a significantly correlation (P<0.01) for right adductor pollicis muscle thickness with all anthropometric parameters. The mean value for normal individuals was significantly greater (P<0.001) than for mild malnourished which was greater (p<0.05) when compared to patients with severe malnutrition.
right adductor pollicis muscle thickness is a low-cost, reliable, and trustworthy method to assess nutritional status that can be easily and safety used in clinical practice for surgical patients.
研究右手拇收肌厚度是否是评估外科手术患者营养状况的可靠方法，以及它与其他人体测量学、生化和临床参数是否相关。
横断面研究，评估87例拟行胃肠道大手术的患者。所有患者均接受整体主观评估、传统人体测量学（上臂围、肱三头肌皮褶厚度、上臂肌肉围）、血清白蛋白、淋巴细胞检测以及双手测量。
优势手的右手拇收肌平均厚度为12.64±3.19毫米，非优势手为12.23±2.9毫米。左拇收肌厚度的敏感性为72.37%，右拇收肌厚度的敏感性为77.33%，截断值由ROC曲线给出（分别为13.4毫米和13.1毫米）。双手的特异性均为100%。右手拇收肌厚度与所有人体测量学参数均存在显著相关性（P<0.01）。正常个体的平均值显著高于轻度营养不良者（P<0.001），轻度营养不良者高于重度营养不良患者（P<0.05）。
右手拇收肌厚度是一种低成本、可靠且值得信赖的评估营养状况的方法，可在临床实践中轻松、安全地用于外科手术患者。
