研究目的:

本研究旨在围绕出血高危重症患者肠内营养实施过程中“安全性不足、定位不精准、并发症风险高”等临床难点,探讨床旁便携式可视肠管在营养管理中的应用价值。通过将可视化技术引入鼻肠管置入与管理全过程,系统评估其在提高置管准确性、降低消化道出血及误吸等并发症风险中的作用。  

Objectives of Study:

This study aims to address clinical difficulties such as insufficient safety, inaccurate positioning and high risk of complications during the implementation of enteral nutrition in critically ill patients at high bleeding risk, and to explore the application value of bedside portable visual intestinal tubes in nutrition management. By introducing visualization technology into the whole process of nasoenteric tube insertion and management, this study systematically evaluates its effects on improving catheterization accuracy and reducing the risks of complications such as gastrointestinal bleeding and aspiration.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

①成年患者(18岁及以上); ②ICU中血小板减少(血小板<50×109)和或凝血功能异常(APTT 50~70s)的患者; ③存在胃管喂养不耐受,需要通过幽门后进行营养补充的患者; ④愿意参与本研究并签署知情同意书。

Inclusion criteria

1. Adult patients (18 years old and above); 2. Patients with thrombocytopenia (platelet count < 50×10^9/L) and/or abnormal coagulation function (APTT: 50~70s) in ICU; 3.

排除标准:

① 合并重度胃肠道疾病或其他严重并发症者,包括活动性消化道出血、肠穿孔、肠梗阻等情况; ② 妊娠期或哺乳期女性; ③ 因特殊生理或病理原因不能实施床旁便携式可视化肠管置入的患者;

Exclusion criteria:

1. Patients complicated with severe gastrointestinal diseases or other serious complications, including active gastrointestinal bleeding, intestinal perforation, intestinal obstruction and other conditions; 2. Pregnant or lactating women; 3. Patients unable to undergo bedside portable visual intestinal tube insertion due to special physiological or pathological factors.

干预措施:

Interventions:

组别:

可视肠管组

样本量:

56

Group:

Visual Intestinal Tube Group

Sample size:

干预措施:

操作前同样肌注盐酸甲氧氯普胺,并以石蜡油润滑导管与管芯。患者保持半卧位,导管以30°角自鼻腔插入,在可视化系统实时监测下,经鼻腔、咽喉、食管进入胃腔。通过影像引导,调整导向角度,使导管依次经胃体、胃窦、幽门进入十二指肠。确认位置后拔除管芯并固定导管。腹部X线证实导管位于幽门远端则为置管成功。

干预措施代码:

Intervention:

Before the operation, intramuscular injection of metoclopramide hydrochloride was administered in the same manner, and the catheter and stylet were lubricated with paraffin oil. The patient was kept in a semi-recumbent position, and the catheter was inserted through the nasal cavity at an angle of 30°. Under real-time monitoring by the visualization system, the catheter passed through the nasal cavity, pharynx and esophagus into the gastric cavity. With image guidance, the orientation angle was adjusted to advance the catheter sequentially through the gastric body, gastric antrum and pylorus into the duodenum. After correct positioning was confirmed, the stylet was removed and the catheter was fixed. Successful intubation was defined as catheter placement distal to the pylorus confirmed by abdominal X-ray.

Intervention code:

组别:

盲置组

样本量:

56

Group:

Blind Insertion Group

Sample size:

干预措施:

采用 Corflo 鼻肠饲管进行操作。置管前10分钟肌注盐酸甲氧氯普胺,润滑导管尖端后,依据鼻—耳—剑突(NEX)法测定插管长度。患者取半卧位,以约30°角经鼻插入胃内。用10 mL生理盐水冲洗导管后,继续前送约5 cm,根据阻力变化调整方向,直至约95 cm处达到预期深度。随后撤出导丝并固定导管。床旁腹部X线显示导管尖端位于幽门后方,视为置管成功。

干预措施代码:

Intervention:

Operations were performed using Corflo nasoenteric feeding tubes. Ten minutes before catheterization, intramuscular metoclopramide hydrochloride was injected. After lubricating the catheter tip, the insertion length was measured according to the nose–ear–xiphoid (NEX) method. The patient was placed in a semirecumbent position, and the tube was inserted into the stomach through the nasal cavity at an approximate angle of 30°. The catheter was flushed with 10 mL of normal saline and then advanced by about 5 cm. The insertion direction was adjusted according to resistance changes until the expected depth of approximately 95 cm was reached. The guide wire was then withdrawn and the catheter secured. Successful tube placement was confirmed when bedside abdominal X?ray showed the catheter tip located behind the pylorus.
