Nasogastric tube insertion using conventional versus bubble technique for its confirmation in anesthetized patients: a prospective randomized study

Abstract Background: Nasogastric tube insertion and confirmation of its position can be difficult in the anesthetized patient. The purpose of the present study was to compare the bubble technique with the conventional method for confirmation of nasogastric tube placement in these patients. Methods: Two hundred sixty adult patients, aged between 20-70 years, posted for surgeries requiring general anesthesia, tracheal intubation, and a nasogastric tube were enrolled in this study. Patients were randomized into 2 groups: Group B (Bubble group) and Group C (Control group). In Group C, a conventional technique using a lubricated nasogastric tube was positioned through the nostril with head remained neutral. In Group B, 2% lidocaine jelly was added to the proximal end to form a single bubble. The correct placement of the nasogastric tube in the stomach was confirmed by fluoroscopy by an independent observer intraoperatively. Results: The duration of nasogastric tube insertion was 57.2 ± 13.3seconds in Group B and 59.8 ± 11.9seconds in Group C (p = 0.111). The confirmation rate of the bubble technique was 76.8% (95% CI: 68.7-83.3), which was significantly better than the conventional method where the confirmation rate was 59.7% (95% CI 50.9-67.9), p< 0.001. When compared to fluoroscopy, bubble technique was found to have a sensitivity of 92.3% (95% CI: 85.6-96.1) with specificity of 81.0% (95% CI: 60.0-92.3), positive predictive value of 96.0% (95% CI: 90.2-98.4), and a moderate negative predictive value of 68.0% (95% CI: 48.4-82.8). Conclusions: The bubble technique of nasogastric tube insertion has a higher confirmation rate in comparison to the conventional technique.

Gastric Perforation Caused by Nasogastric Intubation in a Patient on Peritoneal Dialysis / 대한신장학회지

Nasogastric (NG) intubation is frequently performed in critically ill patients. Although this procedure is associated with considerable complications, physicians tend to neglect its potential complications. There is also rare case of the reports of perforation of the stomach by an NG tube in adults. We report here on a case of gastric perforation that was caused by an NG tube in a peritoneal dialysis patient who required NG tube insertion for enteral feeding, with a review of the relevant literature.

Is Routine Nasogastric Intubation Necessary for Elective Colorectal Surgery?: a Prospective Randomized Controlled Trial

PURPOSE: This study was performed to assess the complications and discomfort of patients with or without a nasogastric tube who underwent elective colorectal surgery and to evaluate the efficacy of the routine practice of employing a nasogastric tube after elective colorectal surgery. METHODS: This study involved a prospective, randomized trial of 100 patients undergoing elective colorectal surgery from February to July 2004. The patients were classified as the nasogastric tube inserted group (NG (+), n=50) and non-inserted group (NG (-), n=50). The inclusion criteria were elective colorectal surgery, age under 70 years and no previous abdominal surgery history. The exclusion criteria were an emergent operation, an overt preoperative bowel obstruction and extensive operations such as pouch surgery and multivisceral resection. RESULTS: The mean age of the subjects was 55 (24~70) years old. There was no difference in terms of age, gender, pathological diagnosis and surgical procedures between the NG (-) and NG (+) groups. A sore throat and nausea was more prevalent in the NG (+) group (P=0.000, P=0.046). The gas passage time was shorter in the NG (-) group than in the NG (+) group (P=0.028). The other variables, such as vomiting, postoperative ileus, postoperative fever, posto-perative atelectasis, postoperative leakage, intraoperativedecompression, stool passage time and the length of the hospital stay revealed no difference between the groups. CONCLUSION: Nasogastric intubation is an uncomfortable procedure for patients and offers no benefit in preventing postoperatve complications. The routine use of a nasogastric tube is not necessary in elective colorectal surgery.

Relationship between Esophageal Lesions Observed by Endoscopy and Nasogastric Intubation: A Study of 185 Cases of Percutaneous Endoscopic Gastrostomy / 대한소화기학회지

BACKGROUND/AIMS: Percutaneous endoscopic gastrostomy (PEG) is a method widely used for long-term enteral nutrition in dysphagia. Mostly, it is preceded by nasogastric intubation (NI) for short-term enteral nutrition; endoscopic findings associated with NI are encountered during PEG. The purpose of this study was to discuss such findings and to delineate a relationship between these findings, especially esophageal lesions and the duration of NI. METHODS: This study involved 185 individuals who had undergone PEG at Kyung Hee Medical Center from January 1999 to May 2002. The medical records were examined retrospectively. RESULTS: The dysfunction of the CNS comprised 98.4% of the causes of dysphagia. The duration of NI was 15.2 weeks on average, with median value of 8.7 weeks, indicating that PEG was performed relatively soon. Endoscopic findings revealed esophagitis in 63 cases, esophageal ulcers in 27 and active bleedings in another 10. The incidence of esophageal lesions was shown to be higher in subjects with duration of NI under 12 weeks than in those with duration over 12 weeks (p=0.032). CONCLUSIONS: PEG was carried out in many cases during the early stages of dysphagia, and NI-associated esophageal lesions appeared to be more prevalent within 12 weeks of NI duration. These results may be of help in deciding the timing of PEG.
