Nutritional status and evaluation of the perioperative fasting time among patients submitted to elective and emergency surgeries at a reference hospital.

ABSTRACT Objective: to evaluate the clinical, surgical, and nutritional profile of surgical patients admitted to a reference hospital in Recife city, Pernambuco state, Brazil. Methods: a cross-sectional study carried out in the wards of the General Surgery Service of Hospital da Restauração Governador Paulo Guerra, from June to September 2018. We included adult and elderly patients (both genders) who were submitted to thoracoabdominal procedures and elective or emergency abdominal surgeries, and in which the assessment of nutritional status could be performed within 72 hours of hospital admission. Data on nutritional status and surgical procedures, as well as clinical and biochemical information, were collected. Results: we studied 140 patients with median age of 45 years. Among all, 59.3% were female and 23% malnourished, according to Subjective Global Assessment. The median preoperative fasting time was 15 hours for size I surgeries and 13.5 hours for size II ones. Longer postoperative hospital stay showed a strong correlation with the total length of hospital stay in both surgical sizes. Malnourished patients had a longer period of perioperative fasting and hospital stay when compared to well-nourished patients (p【摘要】研究目的：评估巴西伯南布哥州累西腓市一家转诊医院收治的外科患者的临床、手术及营养特征。 研究方法：本研究为横断面研究，于2018年6月至9月在巴西保罗·格拉州长康复医院（Hospital da Restauração Governador Paulo Guerra）普通外科病房开展。纳入对象为成年及老年患者（不分性别），需接受胸腹部手术、择期或急诊腹部手术，且可在入院72小时内完成营养状况评估。本研究收集了患者的营养状况、手术相关信息、临床及生化资料。 研究结果：本研究共纳入140例患者，中位年龄为45岁。根据主观全面评定（Subjective Global Assessment）结果，其中59.3%为女性，23%的患者存在营养不良。I级手术患者的术前禁食中位时长为15小时，II级手术患者为13.5小时。无论手术分级如何，术后住院时长与总住院时长均呈强相关性。与营养状况良好的患者相比，营养不良患者的围术期禁食时长及住院时长更长（p
