Bedside placement of nasojejunal tubes: a randomised-controlled trial of spiral- vs straight-ended tubes 总被引:3,自引:0,他引:3
BACKGROUND AND AIMS: The success rate of unguided nasojejunal feeding tube insertion is low, thus often requiring endoscopic or radiological assistance. The spiral end of the Bengmark nasojejunal tube is supposed to aid post-pyloric placement, but no comparative trial has been performed. METHODS: Patients requiring nasojejunal feeding were randomised to have either Medicina (straight) or Bengmark (spiral) nasojejunal tube placed after stratification into those with normal gastric emptying or clinical evidence of delayed gastric emptying. Nasojejunal tubes were placed at the bedside in a standard fashion without radiological guidance by the same person for pre- and/or post-operative feeding. Bolus intravenous metaclopromide (10mg) was given prior to insertion in the abnormal gastric emptying group. Abdominal radiographs were obtained at 4 and 24h, and the primary end-point was jejunal placement at 24h. RESULTS: Forty-seven patients were randomised of which 17 (11 straight, 6 spiral) could not tolerate the nasojejunal tube. Of the 30 remaining patients, 16 had normal gastric emptying. In patients with normal gastric emptying, successful placement at 24h was achieved in 78% (spiral tube), vs 14% (straight tube) (P=0.041). In the abnormal gastric emptying group, success rates were 57% and 0%, respectively (P=0.07). CONCLUSION: Spiral nasojejunal tubes are preferable to straight tubes for bedside unguided post-pyloric feeding in patients with normal gastric emptying. 相似文献

Enteral feeding in primary care has increased markedly over the last decade. It allows patients to be discharged to home or residential care who previously would have remained in hospital. Difficulties do arise for patients, their carers and health professionals, as care of these patients and support for health professionals is often patchy or non-existent. Dietitians are uniquely placed to participate in the management of tube feeding in primary care, provide support and education to patients and their carers, evaluate treatment and promote better outcomes for patients receiving tube feeding. 相似文献

Teaching home enteral feeding is a complex process involving many activities not traditionally performed by dietitians. This survey was undertaken to investigate (a) tasks performed by the dietitian in preparing patients to receive home enteral feeding, (b) the effect of various demographic factors on the dietitian's role, (c) the amount of dietitian time spent preparing a patient for discharge on home enteral feeding, and (d) the types of home enteral feedings currently in use. A questionnaire was tested for reliability and validity, then mailed to 1,168 nutrition support dietitians. Results of the survey indicated that, more often than nurses or physicians, dietitians were responsible for calculating nutrient and fluid needs, selecting formula, determining the home feeding schedule, teaching the patient to prepare blenderized formulas, and teaching the patient to recognize formula intolerance. Dietitians were less often responsible than nurses for psychomotor skills such as teaching the patient to administer the formula, operate the pump, and flush the feeding tube. Dietitians seemed to have a larger role in hospitals with more than 499 beds, in teaching hospitals, and in hospitals with a nutrition support team. Dietitians reported a smaller role when they reported to a contract foodservice company and when their job duties were divided so that more time was spent in clinical dietetics than in nutrition support. However, dietitians in all demographic groups performed all tasks. The average amount of dietitian time spent preparing patients for discharge on home enteral feeding was 168 minutes (2.8 hours) per patient. More patients received gastric feedings (76%) than intestinal feedings (22%).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

BACKGROUND: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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. 相似文献

Transnasal endoscopic placement of nasoenteric tubes (NETs) has been demonstrated to be useful in the critical care setting, with limited data on its role in non-critically ill patients. The authors collected data on consecutive patients from a non-critical care setting undergoing transnasal endoscopic NET placement. All NETs were endoscopically placed using a standard over-the-guidewire technique, and positions were confirmed with fluoroscopy. Patients were monitored until the removal of NETs or death. Twenty-two patients (median age = 62.5 years, 36.4% female) were referred for postpyloric feeding, with main indications of persistent gastrocutaneous fistula (n = 6), gastroparesis or gastric outlet obstruction (n = 5), duodenal stenosis (n = 6), acute pancreatitis (n = 4), and gastroesophageal reflux after surgery (n = 1). Postpyloric placement of NET was achieved in 19 of 22 (86.3%) patients, with 36.8% tube positions in the jejunum, 47.4% in the distal duodenum, and 15.8% in the second part of the duodenum. NET placement was least successful in cases with duodenal stenosis. NETs remained in situ for a median of 24 days (range, 2-94), with tube dislodgement (n = 3) and clogging (n = 5) as the main complications. NET feeding resulted in complete healing of gastrocutaneous fistulae in 5 of 6 patients and provision of total enteral nutrition in 3 of 4 cases of acute pancreatitis and 9 of 11 cases of gastroparesis or proximal duodenal obstruction. Transnasal endoscopy has a role in the placement of NET in non-critically ill patients requiring postpyloric feeding. However, there are some limitations, particularly in cases with altered duodenal anatomy. 相似文献

Recent hospital accreditation guidelines encourage hospital dietitians to monitor patient drug therapy and provide education regarding drug-food interactions. However, information concerning these interactions is lacking, even though they can occur frequently. Minerals in foods can complex with drugs and/or alter the gastrointestinal environment to affect the normal absorption processes of drugs and minerals. There are three types of drug-mineral interactions: (a) malabsorption of the mineral and/or drug; (b) mineral depletion and retention; and (c) drug-mineral interactions induced by simultaneous antacid ingestion. It is recommended that oral drugs be administered on an empty stomach 1 hour before or 2 hours after a meal and at least 2 hours before or after antacid use. A small snack of refined carbohydrates with low nutrient density can be consumed with drugs that cause gastric upset when given on an empty stomach. 相似文献

BACKGROUND: Early postpyloric feeding is considered the accepted method of nutrition support in critically ill patients. Endoscopic and fluoroscopic techniques are associated with the highest percentage of successful placement. The purpose of this study was to compare endoscopic vs fluoroscopic placement of postpyloric feeding tubes in critically ill patients. METHODS: This is a randomized prospective clinical trial. Forty-three patients were randomized to receive feeding tubes by endoscopic or fluoroscopic technique. All procedures were performed at the bedside in the critical care unit. A soft small-bore nonweighted feeding tube was used in all cases. Successful placement was confirmed by either an abdominal x-ray for endoscopic technique or a fluoroscopic radiograph for fluoroscopic technique. RESULTS: Postpyloric feeding tubes were successfully placed in 41 of 43 patients (95%). The success rate using endoscopic technique was 96% (25 of 26), whereas the rate using fluoroscopy was 94% (16 of 17). The average time of successful placement was 15.2 +/- 2.9 (mean +/- SEM) minutes for endoscopic placement and 16.2 +/- 3.2 minutes for fluoroscopic placement, which was not statistically significant (p > .05). CONCLUSIONS: Endoscopic and fluoroscopic placement of postpyloric feeding tubes can safely and accurately be performed at the bedside in critically ill patients. Our results showed no significant difference in the success rate or time of placement between endoscopic vs fluoroscopic placement of postpyloric feeding tubes. 相似文献

Feeding jejunostomy has become a useful method of feeding many patients with upper digestive tract dysfunction from a variety of causes. Although problems infrequently do occur with the tube itself, such as dislodgement or obstruction, most patients tolerate the procedure well. We report here a case of perforation of the jejunum that was caused by the tube itself and required reoperation. As with many problems in surgery, careful attention to technical details should help prevent this and other problems after feeding tube insertion. 相似文献

Background: An electromagnetic tube placement device (ETPD) monitors tip position of feeding tubes (FT) during placement in the digestive tract. It helps to avoid airway misplacement and permits positioning into the small bowel (SB). This study compares the overall agreement between FT tip location as determined by an ETPD vs an abdominal radiograph of the kidneys, ureter, and bladder (KUB). Methods: Using an ETPD, A nurse placed postpyloric FTs in ICU patients. We included all patients in whom the ETPD was used for FT placement. Data were prospectively recorded for 255 days on the rate of successful postpyloric placement, ETPD estimated tip location, and KUB location. Results: 860 tubes were placed in 616 patients, 719 (83.6%) of which recorded for ETPD and KUB. According to the KUB, 81% of tubes were in the SB; however, ETPD suggested 89% were beyond the pylorus. There was moderate agreement beyond what could be attributed to chance between KUB and ETPD tip locations (475 [66.1%], κ score 0.62 [95% confidence interval 0.58–0.67]). More tubes by KUB were distal (134[18.6%]) vs proximal (110[15.3%]) to the suspected location by ETPD (P < .0001. Tubes in or distal to the second half of the duodenum, according to ETPD were rarely in the stomach (<1%). No tubes were proximal to the stomach or placed into the airway. Conclusions: The strong agreement between KUB and ETPD, when tubes were believed to be in the second part of the duodenum or beyond, suggests that KUB is necessary only when the FT tip is suspected to be in the proximal duodenum. 相似文献

OBJECTIVE: To study a new technique of intubating the small bowel using a newly developed nasoenteral feeding tube fitted with a magnet in its tip and guided for placement with an external magnet. METHODS: The study was performed in medical and surgical wards of a university-affiliated Department of Veterans Affairs hospital on 42 patients referred by their attending physicians for tube placement. The newly designed feeding tube was inserted per nares into the stomach using traditional technique. As the tube was advanced, movement of the hand-held steering magnet was designed to guide the tip of the magnetic nasoenteral tube along the lesser curvature of the stomach, through the pyloric sphincter, and into the duodenum. Portable abdominal radiography confirmed the anatomic location of the tube tip. RESULTS: Fifty-one intubations were performed on 42 subjects. In 45 intubations (88%), tubes passed into the duodenum. Twenty-seven (53%) met criteria for optimal placement in the second portion of the duodenum or distally. Six of 11 tubes (55%) that were not optimally placed were advanced to the distal duodenum on repositioning. Median procedure time for the initial intubations was 30 minutes (interquartile range 15-40). Median procedure time for last 10 intubations improved to 13 minutes (interquartile range 5-20). No complications were related to the procedure. CONCLUSIONS: Enteral feeding tube placement using external magnetic guidance is a promising, novel technique which is deserving of further study. 相似文献

A study was undertaken to determine: the qualifications necessary to function on a nutrition support team as perceived by clinical dietitians working in this capacity, the actual role of the clinical dietitian on a nutrition support team, the ideal role of the clinical dietitian on a nutrition support team, and the extent to which clinical dietitians perceive differences between the ideal role expectation and actual performance. A questionnaire was developed and sent to a random sample of 300 clinical dietitians listed as members of a nutrition support service. The respondents indicated that the clinical dietitian should have at least a B.S., R.D., and 2 years' prior work experience before assuming responsibility on a nutrition support team. The dietitians indicated that they consistently take and evaluate diet histories and assess energy and protein needs. Moreover, they viewed these tasks as appropriate. They rarely administer or interpret antigen skin tests and do not perceive this as a function of the dietitian. For all other tasks, dietitians indicated that they should perform the duty or responsibility more often. Over half reported that they did not have adequate educational preparation to assume all of the responsibilities of the clinical dietitian on a nutrition support team. 相似文献

BACKGROUND: Erythromycin enhances gastric emptying and has been suggested to facilitate nasoenteric feeding tube placement in adults. Our primary objective was to evaluate the effect of erythromycin on the transpyloric passage of feeding tubes in critically ill children, and second, to evaluate the effect of erythromycin on the distal migration of duodenal feeding tubes. METHODS: Seventy-four children were randomly assigned to receive erythromycin lactobionate (10 mg/kg) IV or equal volume of saline placebo 60 minutes before passage of a flexible weighted tip feeding tube. Abdominal radiographs were obtained 4 hours later to assess tube placement. If the tube was proximal to the third part of the duodenum, two additional doses of erythromycin/placebo were administered 6 hours apart. Those receiving additional doses had repeat radiographs 14 to 18 hours after tube placement. RESULTS: The number of postpyloric feeding tubes was similar in the erythromycin and placebo treated groups 4 hours after tube insertion (23/37 vs 27/37, p = .5). Of those with prepyloric tubes at 4 hours, none in the erythromycin group and 3 in the placebo group had the tube migrate to the postpyloric position by 14 to 18 hours (p < .05). Of those with postpyloric tubes proximal to the third part of the duodenum at 4 hours, additional doses of erythromycin did not cause more tubes to advance further into the intestine than did placebo (p = .6). CONCLUSIONS: Erythromycin does not facilitate transpyloric passage of feeding tubes in critically ill children. The distal migration of duodenal tubes further into the small bowel is also not enhanced by erythromycin. 相似文献

Hyponatremia (typically defined as serum sodium level < 135 mEq/L) is a common electrolyte abnormality among hospitalized patients. Whether present at admission or acquired during hospitalization, hyponatremia is associated with higher mortality and longer hospital stays. Failure to adequately investigate and treat hyponatremia may also be associated with adverse outcomes. The presence and severity of clinical symptoms largely depend on the rate and extent of the decline in serum sodium; rapid or large decreases may cause serious neurologic complications. The approach to treatment depends on the presence and severity of symptoms, the timing of their onset, the underlying etiology, and the patient's volume status. Patients with euvolemic or hypervolemic hyponatremia usually have inappropriately elevated levels of arginine vasopressin, which stimulates water reabsorption even in the presence of low serum osmolality. Tolvaptan is an orally active, selective V2-receptor antagonist that blocks the effects of arginine vasopressin in the renal collecting duct to promote aquaresis without increasing sodium or potassium excretion; as a result, it increases serum sodium in a controlled manner. Tolvaptan offers a mechanism-based treatment option for patients with euvolemic or hypervolemic hyponatremia who have serum sodium levels < 125 mEq/L or persistent symptoms resistant to fluid restriction. 相似文献
