There is an increasing demand for enteral feeding in intensive care unit (ICU) patients. However, gastroparesis is common, and jejunal placement with gastric decompression leads to delays in feeding. In an attempt to minimize delays, we describe our technique and results with transnasal endoscopic placement of double-lumen gastric aspiration, jejunal feeding tubes (DLFT).
Fifty-one consecutive ICU patients referred for nutrition support were studied; 29% had respiratory failure, 28% acute head injury, and 33% acute pancreatitis. A 5.8-mm ultraslim video endoscope was used to place a guidewire through the nose terminating beyond the Ligament of Treitz. After withdrawal of the endoscope, a DLFT was passed over the wire. Final position of the tube was checked and adjusted under direct vision by reendoscopy though the opposite nasal passage.
Initial placement of the guidewire and DLFT was successful in 46 of 51 patients. Massive gastric dilatation and acute pancreatitis complicated by duodenal compression impeded full duodenoscopy in 5 patients, necessitating fluoroscopy for correct guidewire deployment. In confirming correct tube placement, there was near perfect concordance between reendoscopy and x-ray (45/46). Previously unrecognized upper gastrointestinal tract pathology was detected in most patients, with acute gastritis in 47, superficial gastric ulceration in 24, and erosive esophagitis in 5.
Transnasal endoscopic placement of feeding tubes in the ICU is quick, effective, and minimally disruptive of intensive therapy. In addition, it can reveal unrecognized pathology, which potentially could lead to improvements in overall medical care.
重症监护病房(ICU)患者对肠内营养的需求日益增加。然而,胃轻瘫很常见,空肠置管并进行胃减压会导致喂养延迟。为尽量减少延迟,我们描述了经鼻内镜放置双腔胃吸引空肠喂养管(DLFT)的技术及结果。
对51例连续转诊至ICU接受营养支持的患者进行研究;其中29%患有呼吸衰竭,28%有急性颅脑损伤,33%有急性胰腺炎。使用5.8毫米超薄视频内镜经鼻置入导丝,使其末端越过Treitz韧带。在内镜退出后,将DLFT沿导丝置入。通过对侧鼻腔再次内镜直视检查来检查并调整导管的最终位置。
51例患者中有46例成功完成了导丝和DLFT的初始置入。5例患者因胃大量扩张和急性胰腺炎合并十二指肠受压而妨碍了全十二指肠镜检查,需要借助荧光透视来正确部署导丝。在确认导管位置正确方面,再次内镜检查与X线检查结果几乎完全一致(45/46)。大多数患者检测出了之前未被识别的上消化道病变,其中47例为急性胃炎,24例为浅表性胃溃疡,5例为糜烂性食管炎。
在ICU经鼻内镜放置喂养管快速、有效,对重症治疗的干扰最小。此外,它还能发现未被识别的病变,这可能会改善整体医疗护理。
