2021ESPEN外科营养治疗实践指南

1.1术前是否需要禁食？

推荐1

Preoperative fasting from midnight is
unnecessary in most patients. Patients undergoing surgery, who are considered
to have no specific risk of aspiration, shall drink clear fluids until two
hours before anesthesia. Solids shall be allowed until six hours before
anesthesia. (Grade of recommendation A – strong consensus)

大部分患者不需要从术前当晚开始禁食。无误吸风险的患者可在麻醉前2小时饮用清流质，麻醉前6小时进食固体食物。（推荐等级A-强烈同意）

1.2择期手术患者使用碳水化合物进行术前代谢准备能否获益？

推荐2

In
order to reduce perioperative discomfort including anxiety oral preoperative
carbohydrate treatment (instead of overnight fasting,
the night before and two hours before surgery) should be administered (B). To impact postoperative insulin resistance and LOS, preoperative carbohydrates can be considered in patients undergoing major surgery (0). (Grade of
recommendation B/0 – strong consensus)

手术前夜以及术前2小时口服碳水化合物（不需要术前禁食禁饮）有助于减少焦虑等不适（B）。大手术患者可考虑术前使用碳水化合物改善术后胰岛素抵抗和缩短住院时间（Length of stay, LOS）（0）。（推荐等级B/0-强烈同意）

1.3术后是否有必要中断经口营养摄入？

推荐3

In most instances, oral nutritional
intake shall be continued after surgery without interruption. (Grade of
recommendation A – strong consensus)

– strong consensus)

推荐在大手术前后评估患者的营养状况。（推荐等级GPP-强烈同意）

推荐7

Perioperative nutritional support
therapy is indicated in patients with malnutrition and those at nutritional
risk. Perioperative nutritional therapy should also be initiated if it is
anticipated that the patient will be unable to eat for more than five days
perioperatively. It is also indicated in patients expected to have low oral
intake and who cannot maintain above 50% of the recommended intake for more
than seven days. In these situations, it is recommended to initiatenutritional support therapy (preferably by the enteral route – oral
nutritional supplements – tube feeding) without delay. (Grade of recommendation
GPP – strong consensus)

推荐对存在营养不良及营养风险的患者开展围手术期营养治疗。若预计围手术期超过5天无法经口进食，或经口进食低于50%推荐摄入量超过7天，也应尽快开展围手术期营养治疗（首选肠内途径，包括口服营养补充（Oral nutritional supplements，ONS）和管饲营养）。（推荐等级GPP-强烈同意）

推荐8

If the energy and nutrient
requirements cannot be met by oral and enteral intake alone (<50% of caloric
requirement) for more than seven days, a combination of enteral and parenteral
nutrition (PN) is recommended (GPP). PN shall be administered as soon as
possible if nutrition therapy is indicated and there is a contraindication for
enteral nutrition (EN), such as in intestinal obstruction. (A) (Grade of recommendation GPP/A – strong
consensus)

若单独经口和经肠内营养无法满足能量及营养需求（<50%热卡需求）超过7天，推荐联合使用肠内营养（enteral nutrition，EN）与肠外营养（parental nutriton，PN）（GPP）。若患者需要营养治疗但存在EN禁忌（如肠梗阻），推荐尽早开展PN（A）。（推荐等级GPP/A-强烈同意）

推荐9

For the administration of PN, an
all-in-one (three-chamber bag or pharmacy prepared) should be preferred instead
of a multibottle system. (Grade of recommendation B – strong consensus)

PN应以全合一（三腔袋或药房配置）形式给予，而不是多瓶分开输注。（推荐等级B-强烈同意）

2.5富含免疫营养素的特殊口服/肠内营养配方的使用指征是什么？

推荐13

Peri- or at least postoperative
administration of specific formula enriched with (arginine, omega-3-fatty
acids, ribonucleotides) should be given in malnourished patients undergoing
major cancer surgery (B). There is currently no clear evidence for the sole use
of these formulas enriched with immunonutrients vs. standard oral nutritional
supplements (ONS) in the preoperative period (0). (Grade of recommendation B/0
– consensus)

推荐行癌症大手术的营养不良患者在围手术期或至少在术后使用富含精氨酸、omega-3脂肪酸、核糖核苷酸的特殊营养制剂（B）。目前尚无充分证据证明术前单独使用含此类特殊免疫营养制剂的ONS的效果优于普通ONS。（推荐等级B/0-同意）

3.1哪些患者可以从术前营养治疗中获益？
