背景:
- 予後栄養指数 (PNI) は,血清アルブミンとリンパ球数を用いて栄養状態と免疫状態を評価します.
- 冠動脈バイパス移植 (CABG) 患者の未検出の栄養失調は,発症率と死亡率を増加させる可能性があります.
- PNIは,手術前栄養支援を必要とする高リスクのCABG患者を特定することができます.
研究 の 目的:
- PNIと30日間の死亡率および罹患率との関連を調査する.
- 心肺バイパス (CPB) によるCABGを受ける患者の術前マーカーとしてPNIを評価する.
主な方法:
- CABGとCPB (2021-2022) を受けた60歳以上の患者435人を含む.
- すべての患者に対する PNI の計算.
- 死亡率と発症率とのPNIの関連性を評価するために,多変量分析を使用した.
主要な成果:
- 平均PNIは50.65±6.33.3でした.

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
