A painful and knotted nasogastric tube

Knotted Nasogastric Tube Removed With a Bronchoscope

Nasogastric (NG) tube insertion is a routine procedure performed for a variety of indications, such as delivering enteral nutrition. NG tubes can be associated with complications, including knotting of the tube. The case of a 68-year-old who was admitted to the hospital for AIDS complicated by septic shock is presented. The patient received an NG tube to provide enteral nutrition, which was subsequently found to be clogged. An X-ray of the pharynx revealed a knot at the distal end of the NG tube. The knotted NG tube was removed with a fiberoptic bronchoscope through the nostril. The knotting of an NG tube is a rare complication. Clinicians should be aware of alternative methods of removing knotted NG tubes, including the use of a fiberoptic bronchoscope.

Should nasogastric tube be used routinely in patients undergoing cardiac surgery? A narrative review

BACKGROUND AND AIM

Nasogastric tube (NGT) use has been common in the immediate postoperative period in surgical patients for decades. Potential advantages include the decompression of gastric contents and the early administration of time-sensitive medications. However, its routine use after cardiac surgery has not been established as a gold standard yet. The NGT use for prevention of postoperative nausea and vomiting has been a matter of debate in literature. Also, NGT use has also been associated with the incidence of some respiratory and gastrointestinal complications and it may be a source of significant pain and discomfort to patients. In this article, we review the current available literature regarding the use of NGT during and immediately after cardiac surgery, with particular emphasis on its potential role in enhanced postoperative recovery.

METHODS

We performed a database search in October 2021 using Embase, Cochrane Library, and Medline to identify studies that examined the use of NGT in patients that underwent cardiac surgery. Data and literature about NGT's impact on post-operative nausea and vomiting, early administration of medications, interference with imaging, post-operative complications, respiratory complications, gastrointestinal complications, pain and discomfort, and enhanced recovery after surgery were examined.

RESULTS

Three reports investigating the use of NGT to reduce post-operative nausea and vomiting were examined with sample sizes of 114, 104, and 202. The use of NGT did not significantly reduce the incidence of post-operative nausea and vomiting in 2/3 of the studies: a 2% nausea reduction with NGT (p < 0.05), a 7.7% nausea reduction with NGT (p = 0.6), and a 14% vomiting reduction with NGT (p = 0.007). The prevalence of pneumonia following NGT use has been shown to vary ranging from 4 to 95% with associated mortality rates of 17 to 62%.

CONCLUSION

Based on our findings, there is currently not sufficient evidence to support the routine use of NGT during cardiac surgery. Further research is needed to establish the role of NGT in this patient population.

An unusual instance of stridor: airway obstruction from a nasogastric tube knot in a 1-month old infant

We report a 1 month old infant with a spontaneously knotted nasogastric tube. Attempted removal of the nasogastric tube was unsuccessful, prompting further investigation. Plain radiographs revealed a large, multi-looped knot impacted in the nasopharynx and oropharynx. The tube was subsequently removed through the mouth under general anesthesia without complication, revealing a large, impressive knot of the distal end of the nasogastric tube.

Reducing the pain of nasogastric tube intubation with nebulized and atomized lidocaine: a systematic review and meta-analysis

Nasogastric tube (NGT) intubations occur frequently in clinical practice and can be a painful procedure for patients. A systematic review of current knowledge concerning the use of nebulized lidocaine to reduce the pain of NGT insertion was conducted in order to develop evidence-based guidelines. In addition, a meta-analysis of appropriate randomized controlled trials (RCTs) was performed. The databases included PubMed (1996-2009), ProQuest (1982-2009), CINAHL (1982-2009), and the Cochrane Central Register of Controlled Trials (2009), and reference lists of articles. Experts in this field also were contacted. Two investigators selected the research based on inclusion criteria and reviewed each study's quality according to the Jadad scale. Five RCTs with 212 subjects were identified. A total of 113 (58%) subjects were women. The mean age of treatment and control groups was 59.6 and 55 years, respectively. The countries of studies were the United States, United Kingdom, Australia, Canada, and Thailand. In the treatment groups, the use of lidocaine concentration was 4% and 10%. The pooled effect size was 0.423 (95% confidence interval: 0.204-0.880; Z=-2.301; P=0.021), indicating that the use of nebulized lidocaine before NGT insertion can decrease pain by 57.7%. There is insufficient evidence to recommend the dosage, concentration, or delivery method. Further research is needed to articulate a comprehensive clinical guideline.
