Early nasojejunal tube feeding versus nil-by-mouth in acute pancreatitis: A randomized clinical trial

Background/objectivesThere is substantial evidence of superiority of enteral nutrition (EN) to parenteral nutrition in acute pancreatitis (AP) treatment, but few studies evaluated its effectiveness compared to no intervention. The objective of our trial was to compare the effects of EN to a nil-by-mouth (NBM) regimen in patients with AP. MethodsPatients with AP were randomized to receive either EN via a nasojejunal tube initiated within 24 h of admission or no nutritional support. Systemic inflammatory response syndrome (SIRS) was assessed as the primary outcome. Secondary outcomes included mortality, organ failure, local complications, infected pancreatic necrosis, surgical interventions, length of hospital stay, adverse events and inflammatory response intensity. Outcomes were compared using Student's t-test and Mann–Whitney U test as appropriate. Results214 patients were randomized in total, 107 to each group. SIRS occurrence was similar between groups, with 48 (45%) versus 51 (48%), respectively (RR 0.94; 95% CI 0.71–1.26). No significant reduction of persistent organ failure (RR 0.81; 95% CI 0.52–1.27) and mortality (RR 0.59; 95% CI 0.28–1.23) was present in the EN group. There were no significant differences in other outcomes between the groups. When analyzing the occurrence of SIRS and mortality in subgroup of patients with severe disease no significant differences were noted. ConclusionOur results showed no significant reduction of persistent organ failure and mortality in patients with AP receiving early EN compared to patients treated with no nutritional support (NCT01965873).

Practice Guideline Recommendations on Perioperative Fasting: A Systematic Review.

Traditionally, perioperative fasting consisted of being nil by mouth (NBM) from midnight before surgery and fasting postoperatively until recovery of bowel function. These outdated practices persist despite emerging evidence revealing that excessive fasting results in negative outcomes and delayed recovery. Various evidence-based, multimodal, enhanced recovery protocols incorporating minimized perioperative fasting have arisen to improve patient outcomes and streamline recovery, but implementation remains limited. This article aims to review current fasting guidelines, assess their quality, summarize relevant recommendations, and identify gaps in evidence. A systematic literature search of Medline and CINAHL and a manual search of relevant websites identified guidelines containing suitable grading systems and fasting recommendations. Guideline quality was assessed using the Appraisal of Guidelines Research and Evaluation (AGREE) tool. Grading systems were standardized to the American Society for Parenteral and Enteral Nutrition format and recommendations summarized based on grading and guideline quality. Nineteen guidelines were included. Rigor of development scores ranged from 29%-95%, with only 8 guidelines explicitly declaring the use of systematic methodology. Applicability scores were lowest, averaging 32%. Ten recommendation types were extracted and summarized. Strong and consistent evidence exists for the minimization of perioperative fasting, for a 2-hour preoperative fast after clear fluids, and for early recommencement of oral food and fluid intake postoperatively. This article presents several high-level recommendations ready for immediate implementation, while poorly graded and inconsistent recommendations reveal key areas for future research. Meanwhile, guideline quality requires improvement, especially regarding rigor of development and applicability, through systematic methodology, reporting transparency, and implementation strategies.

The effect of enteral nutrition on adipokines in patients with acute pancreatitis.

The mechanism behind the beneficial effects of enteral nutrition (EN) for patients with acute pancreatitis (AP) is largely unknown. Adipokines, as mediators of metabolism and inflammation, may be a possible mechanism. The study aimed to investigate the effect of EN on adipokines early in the course of AP. Patients with AP were randomised to EN or nil-by-mouth (NBM). Blood samples were taken on the first 4 d of admission and adipokine concentrations for adiponectin, leptin, omentin, resistin and visfatin were determined by ELISA assays. A linear mixed model analysis was run to determine differences in adipokine concentrations between the two study groups. A total of thirty-two patients were included in the study. Omentin concentrations were significantly higher in patients who received EN compared with NBM across the first 4 d of admission (mean difference: 11·6 (95 % CI 1·0, 22·3) ng/ml; P = 0·033). Leptin concentrations were significantly higher in patients who received EN compared with NBM after adjusting for age, sex and BMI (mean difference: 2·3 (95 % CI 0·1, 4·5) ng/ml; P = 0·037). No significant difference in adiponectin, resistin or visfatin concentrations were observed between the two study groups. EN significantly increases omentin and leptin concentrations in AP. Future research should be directed towards understanding whether these adipokines are responsible for the therapeutic benefits of EN.

Dysphagia and Factors Associated with Respiratory Infections in the First Week Post Stroke

Background: Dysphagia occurs in approximately half of the stroke patients and is associated with respiratory infections; however, it is unclear what other factors contribute to an increased risk. This study aimed to provide evidence on factors associated with respiratory infections in the very acute stroke period. Methods: Retrospective review of 536 stroke patients admitted to Australian Hospitals in 2010. Data were collected on 37 clinical and demographic parameters. Univariable and multivariable logistic regression was performed. Results: The overall incidence of respiratory infection was 11%. On admission, requiring full assistance with mobility [OR 6.48, 95% CI 1.35, 31.16] and urinary incontinence [OR 3.21, 95% CI 1.16, 8.87] were associated with respiratory infections. During the first week post stroke nasogastric tubes (NGT) [OR 3.91, 95% CI 1.73, 8.80] and Nil By Mouth (NBM) [OR 5.62, 95% CI 1.54, 20.46] were associated with respiratory infections. Impaired GCS, ischaemic stroke and significantly impaired mobility were associated with swallowing difficulties. Conclusion: This study of a large cohort of acute stroke patients supports research indicating aspiration pneumonia is multifactorial in nature. NGT were associated with increased risk of respiratory infections and may contribute to infections by promoting oropharyngeal colonisation. Patients with severely impaired mobility were also at very high risk of respiratory infection.

Overfeeding and overhydration in elderly medical patients: lessons from the Liverpool Care Pathway

This paper describes three elderly patients who were admitted to hospital with aspiration pneumonia. They were kept nil by mouth (NBM) for a number of days, while being given intravenous hydration initially and enteral feeding subsequently. During that time they deteriorated and appeared to be dying, so the Liverpool Care Pathway (LCP) for the dying was used to support their care. Artificial nutrition and hydration were stopped. They quickly improved and the LCP was discontinued. Two of the patients deteriorated again on reintroduction of enteral feeding and/or intravenous fluids, only to improve a second time following withdrawal of feeding and fluids. Vulnerable elderly patients should not be made NBM except as a last resort. Clinicians should be alert to the possibility of refeeding syndrome and overhydration as reversible causes of clinical deterioration, particularly in frail elderly patients. Use of the LCP in these patients provided a unique opportunity to witness the positive effects of withdrawal of excessive artificial nutrition and hydration.

Nursing management of patients who are nil by mouth

This article examines how to manage patients who are nil by mouth (NBM) and maintain optimal nutritional status. Pre-operative fasting and other reasons why patients might be NBM, methods of administering nutritional support and nursing considerations, such as mouth care, urine output, intravenous therapy and skin assessment are also discussed. The article provides an insight into the psychological effects on patients who are NBM and emphasises the importance of patient education.
