【摘要】 目的了解普外择期手术住院病人是否存在营养不良，判断营养不良的类型和程度，制定治疗方案，监测治疗效果，对病人预后进行判定。方法普外科15个月内收治1002例择期手术住院病人。男430例，女572例，最大年龄89岁，最小年龄15岁。消化道内疾病411例（良性疾病181例，恶性疾病230例），消化道外疾病591例（良性疾病506例，恶性疾病85例）。入院后三天内对有所有患者多项营养指标进行检测。1．人体测量：WT／HT（与理想体重比）、TSF（上臂皮褶厚度）、MAC（上臂周径）、AMC（上臂肌围）、GS（握力）。2．实验室检查：Hb（血红蛋白），Alb（血浆白蛋白），Tf（转铁蛋白），CHI（尿肌酐身高指数），Tlc（淋巴细胞总数）。3．生物电阻抗测体服。人体测量及24小时尿标本收集均由专人负责，实验室检查由本院检验科承担。评定营养不良程度采用多数学者应用的标准。体脂测定用北京军区军事医学研究所研制的“人体脂肪分析仪”，并按国人不同年龄体脂（％）建议值进行评定。结果各营养指标异常的发生率为：WT／HT18．1％（181／1002）、TSF25．8％（259／1002）、AMC22．2％（222／1002）、GS65.5％（674／989），Hb51.2％（410／801）、Alb6.1（51／837）、Tf24.9％（87／349）、CHI47．6％（255／536）、TIC23更多还原

【Abstract】 objective Appraisal of nutrition status of patients has been recognized to be important. The objective of nutrition assessment is to understand whether the patients are malnutritioned and to evaIuate the tyPe and degree of malnutrition for therapy plan,evalnating therapy effects and the prognosis.Methods We treated 1 002 (430 M, 572 F) selected operative cases (aged 15 to 89) within 15 months in general surgical dept of our hospital. Of 1002 cases,411 have digestive tract disease (benign 181, malignant 230) and 591 have nondigestive tract disease (benign 506, m0alignant 85). Several nutrition indexes are examined in all patients in three days after hospitalization. Above mentioned indexes included: 1, Anthropometry: WTAlT, TSF, MAC, AMC and GS. 2. laboratory examnation: Hb, Alb, Tf, CHI and TLC. 3.fory fat measurement with bioetectricity impedance method. A special person was responsible for the anthropometry and the collection of 24 hours urine samples. Cinical laboratory of our hospital undertaked the laboratory examination. In assereing the degree of malnutrition,we adopted the criteria that the ma jority of scholars applied. Measuring they fat was performed using "Body Fat Analysis Ap pliance" made by Institution of Military Medicine of BeiJing Military Area and its nutrition effect was appraised according to suggested criterion for they fat (% ) of different aged chinese.Results The incidence of abnormal nutrition indexes: WT/HT(18. 1% ), TSF(25. 8 % ), AMC(22. 2 % ), GS(65. 5 % ), Hb(51. 2),Alb (6. 1 % ) TG (24. 9% ),CHI(47. 6% ),TLC (23. 7% ),Fat (63. 6% ). Arnong these patients,42. 3% had 1 ~ 2 abnormal parameters,41. 3 % had 3 ~ 5 abnormal and 11. 4 %, 6 ~ 8 abnormal. Of all patients with lower Alb,44 cases (81 % ) were accompanied with other 3~7 abnormal parameters. foth these results demonstrated that the incidence of malnutrition of surgery inpatients is very high. It’s very important for surgeons to evaluate nutrition status of paitnets before surgery. From present research, no one or a group of examination can diagnose maInutrition perceptively and distinctively. Most of scholars emphasized multiple parameters combi nation and synthetic assessment. Component of human body is measured by biolelectricity impedance technique, which is a new methed applied to clinic in recent years. It’s mechanism is to utilize the difference of conductibility between fat tissue and nonfat tissue for e valuating they fat content. Conclusions It’s a noninvasive detecting method, simple, quick, safe and economical. It is also favourable for schokirs and has widely applied prospect.更多还原
