Applications and techniques of gastrointestinal intubation.

Gastrointestinal intubation has found increasing applications over the past several years. Although usually an uncomplicated procedure, passage of an intestinal tube may be impeded by ineffective peristalsis, obstructing lesions or surgical alteration of the normal anatomy. A variety of techniques are described for passing tubes into the stomach, duodenum and small bowel. These techniques are an outgrowth of those initially developed for manipulating tubes through the vascular, biliary and genitourinary systems. The characteristics of the various decompression and alimentation tubes as well as the dangers of gastrointestinal intubation are also discussed.

Gastrointestinal intubations: nursing considerations.

This article describes 10 special therapeutic tubes utilized in gastroenterology. The discussion includes a description of each tube; categories are developed by anatomical site as well as the number of lumens in each tube. Several tubes are not discussed due to previous development in the literature or specialty purposes limited to diagnostics: esophageal manometry, Levin, Salem sump, gastrostomy tubes, bougies, dilators, the Dreiling tube and the Rubin-Quinton tube. Many of the tubes discussed are often utilized in the inpatient setting on a ward and may not be as familiar to the gastroenterology nurse or associate in an endoscopy suite.

Effect of gastrointestinal intubation on the passage of a solid meal through the stomach and small intestine in humans.

The effect of a gastrointestinal tube on the passage of a radiolabeled solid meal through the stomach and small intestine was investigated in 22 healthy volunteers using the gamma camera and breath hydrogen analysis. Gastric emptying was significantly retarded in 12 subjects, who had an intestinal tube in situ compared with 10 control subjects, who were not intubated (t 1/2 = 1.5 +/- 0.1 vs. 1.2 +/- 0.1 h; p less than 0.02). On the other hand, colonic filling was significantly accelerated in the intubated subjects (onset: 1.2 +/- 0.2 vs. 2.9 +/- 0.4 h; p less than 0.001; t 1/2: 4.1 +/- 0.3 vs. 5.6 +/- 0.5 h; p less than 0.001). Values for small bowel residence were significantly reduced in the intubated subjects (5.3 +/- 0.5 vs. 6.5 +/- 0.6 food hours; p less than 0.001). Paired studies, carried out in an additional 11 normal subjects, confirmed that small bowel transit time was significantly shortened during intestinal intubation in the same individuals (2.0 +/- 0.3 vs. 3.6 +/- 0.4 h). These results suggest that intubating the gastrointestinal tract may profoundly affect its function.

Mechanical intestinal obstruction in patients with gynecologic disease: a review of 368 patients.

To review the management of intestinal obstruction associated with gynecologic disease, the authors studied the records of 368 patients with acute intestinal obstruction. Most patients (83%) had gynecologic malignancies. Obstruction of the small intestines was more common than obstruction of the large intestines (77% versus 23%). Major causes of mechanical small bowel obstruction included extrinsic neoplasms (62%, mostly ovarian carcinomas), radiation therapy-associated strictures and adhesions (17%), postoperative adhesions (14%), and inflammatory strictures and adhesions (3%). Obstruction of the colon was caused mainly by extrinsic neoplasms (45%), strictures and adhesions associated with radiation therapy (26%), fecal impaction (9%), and intrinsic neoplasms (8%). Gastrointestinal intubation successfully relieved 81% of small bowel obstructions caused by postoperative adhesions. Tube suction alone was rarely successful when the obstruction was caused by malignant neoplasms. The prognosis was dependent on the cause of the underlying disease. The cases studied in this report were compared with a large number of cases of bowel obstruction in general surgery. It is concluded that bowel obstruction associated with gynecologic disease has unique features deserving wider recognition.

[The use of the Dreimlich probe for obtaining samples in a postoperative study of biliopancreatic function in cholecystectomized patients].

We have performed a clinical study involving patients with symptomatic gallstones and indications for surgery, to analyze the biliary and pancreatic response to the quality of dietary fat (degree of unsaturation). As part of the investigative method, we have designed a clinical protocol adapted to the needs of the study, in this respect, we have used gastrointestinal intubation to obtain independent samples of gastric and duodenal juices, by means of a long nasoduodenal tube or a modified Dreimlich tube, placed manually in the intraoperative period, during the cholecystectomy. The characteristics of the tube are such that its manipulation is difficult, which led to situations postoperatively and during sampling, which may alter or invalidate the obtained drainage material. In the present study we define the protocol and the phases of the investigation, and we reflect on the usefulness of the Dreimlich tube as a method, analyzing its advantages and disadvantages.

Safety and efficacy of nasogastric intubation for gastrointestinal bleeding after myocardial infarction: an analysis of 125 patients at two tertiary cardiac referral hospitals.

Our purpose was to analyze risks versus benefits of nasogastric (NG) intubation for gastrointestinal (GI) bleeding performed soon after myocardial infarction (MI). While NG intubation and aspiration is relatively safe, clinically beneficial, and routinely performed in the general population for recent GI bleeding, its safety after MI is unstudied and unknown. In addition to the usual complications of NG tubes, patients status post-MI may be particularly susceptible to myocardial ischemia or cardiac arrhythmias from anxiety or discomfort during intubation. We studied NG intubation within 30 days of MI in 125 patients at two hospitals from 1986 through 2001. Indications for NG intubation included melena in 55 patients; fecal occult blood with an acute hematocrit decline, severe anemia, or sudden hypotension in 37; hematemesis in 18; bright red blood per rectum in 8; and dark red blood per rectum in 7. The intubation was performed on average 5.3 +/- 7.2 (SD) days after MI. NG aspiration revealed bright red blood in 38 patients, "coffee grounds"-appearing blood in 45, and clear (or bilious) fluid in 42. Among 114 of the patients undergoing esophagogastroduodenoscopy (EGD), EGD revealed the cause of bleeding in 79 (95%) of 83 patients with a grossly bloody NG aspirate versus 12 (39%) of 31 patients with a clear aspirate (P < 0.0001, OR = 31.3, OR CI = 9.4-103.1). Among 85 patients undergoing EGD within 16 hr of NG intubation, stigmata of recent hemorrhage were present in 28 (42%) of 66 with a bloody NG aspirate versus 3 (16%) of 19 with a clear aspirate (P = 0.06, OR = 3.93). Among 35 patients undergoing lower GI endoscopy, lower endoscopy revealed the cause of bleeding in 14 (56%) of 25 patients with a clear NG aspirate versus 1 (10%) of 10 patients with a grossly bloody aspirate (P < 0.04, OR = 11.46, OR CI = 1.55-78.3). The two NG tube complications (epistaxis during intubation and gastric erosions from NG suctioning) were neither cardiac nor major (requiring blood transfusions). This study suggests that short-term NG intubation is relatively safe and may be beneficial and indicated for acute GI bleeding after recent MI. Aside from improving visualization at EGD, the potential benefits include providing a rational basis for the timing of endoscopy (urgent versus semielective), for prioritizing the order of endoscopy (EGD versus colonoscopy), and for avoiding or deferring endoscopy in low-yield situations (e.g., colonoscopy when the NG aspirate is bloody). These benefits may be particularly relevant in patients after recent MI due to their increased endoscopic risks.
