Abstract
Objective: Nasogastric tube (NGT) insertion is one of the most painful procedures in the emergency department (ED). A recent study determined that giving intravenous (IV) midazolam before NGT insertion decreased patients' pain; however, the sample size was insufficient to draw the conclusions on safety. We conducted a retrospective chart review of patients who received IV midazolam for NGT insertion to determine the frequency of adverse events. Methods: All patients treated at a Level 1 trauma center ED from June 2016 to June 2019 who received IV midazolam for NGT insertion were included. The medical records were screened for the following serious adverse events: hypoxia, respiratory suppression, excessive somnolence/sedation, hemodynamic instability, epistaxis, vomiting, and choking. Adverse events, patient demographics, chief complaint, diagnosis, disposition, number of midazolam administrations, dose per administration, and total dose were recorded for the analysis. Findings: Three out of 159 participants (2%) were identified as having an adverse event. In two cases, the adverse event was hypoxia, which was corrected with the administration of supplemental oxygen through nasal cannula. The third adverse event was somnolence noted in a patient who was also hypotensive and in atrial fibrillation around the time of midazolam administration. Conclusion: It is safe to premedicate patients with midazolam before NGT insertions. Patients with borderline oxygen saturation and those receiving opioid analgesics may warrant dose titration with close vital sign monitoring.

Does Routine Midazolam Administration Prior to Nasogastric Tube Insertion in the Emergency Department Decrease Patients' Pain? (A Pilot Study). Acad Emerg Med 2016; 23:766-71. [PMID: 26990304 DOI: 10.1111/acem.12961] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2015] [Revised: 02/26/2016] [Accepted: 02/28/2016] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Patients report pain and discomfort with nasogastric tube (NGT) intubation. We tested the hypothesis that premedication with midazolam alleviates pain during NGT placement in the emergency department (ED) by > 13 on a 100-mm visual analog scale (VAS). METHODS We performed a double-blind randomized controlled pilot study, assigning ED patients requiring NGT placement to midazolam or placebo. All patients received intranasal cophenylcaine; additionally, they received an intravenous (IV) dose of the study drug, either 2 mg of IV midazolam or saline control. Nurses placed NGTs while observed by research staff, who then interviewed subjects to determine the primary outcome of pain using a VAS. Additional data collected from patients and their nurses included discomfort during the procedure, difficulty of tube insertion, and complications. RESULTS We enrolled 23 eligible patients and obtained complete data in all: 10 midazolam and 13 controls. We found a significant reduction in mean pain VAS score of -31 (95% confidence interval = -53 to -9 mm) with 2 mg of midazolam (mean ± SD = 52 ± 30 mm), compared to placebo (mean ± SD = 21 ± 18 mm), more than double the effect size considered clinically relevant. Treatment did not impact ease of placement and there were no serious adverse effects. CONCLUSIONS Premedication with 2 mg of IV midazolam reduces pain of NGT insertion in ED patients without the need for full procedural sedation.

Abstract
OBJECTIVES Nasogastric tube insertion is a common procedure in children that is very painful and distressing. Although nebulized lidocaine has been shown to be effective in reducing the pain and discomfort of nasogastric tube insertion in adults, there have been no similar studies in children. We set out to investigate the role of nebulized lidocaine in reducing pain and distress of nasogastric tube insertion in young children. METHODS We conducted a randomized, double-blind, placebo-controlled trial of nebulized 2% lidocaine at 4 mg/kg versus saline placebo during nasogastric tube insertion at a tertiary urban pediatric emergency department. Patients were eligible if they were aged from 1 to 5 years with no comorbid disease and a clinical indication for a nasogastric tube. Nebulization occurred for 5 minutes, 5 minutes before nasogastric tube insertion. Video recordings before, during, and after the procedure were rated using the Face, Legs, Activity, Cry, and Consolability (FLACC) pain and distress assessment tool (primary outcome measure) and pain and distress visual analog scale scores (secondary outcome measures). Difficulty of insertion and adverse events were also assessed. RESULTS Eighteen participants were nebulized with 2% lidocaine and 18 participants with normal saline. Nebulization was found to be highly distressing. FLACC scores during nasogastric tube insertion were very high in both groups. There was a trend in the post-nasogastric tube insertion period toward lower FLACC scores in the lidocaine group. Visual analog scale scores for this postinsertion period were significantly lower in the lidocaine arm for pain and distress. There were no significant differences between groups in terms of difficulty of insertion and the number of minor adverse events. The study was terminated early because of the distress and treatment delay associated with nebulization. CONCLUSIONS Nasogastric tube insertion results in very high FLACC scores irrespective of lidocaine use. Nebulized lidocaine cannot be recommended as pain relief for nasogastric tube insertion in children. The delay and distress of nebulization likely outweigh a possible benefit in the postinsertion period.

Abstract
OBJECTIVE To compare the safety and patient-reported effectiveness of two regimens for conscious sedation during enteroclysis. MATERIALS AND METHODS We surveyed two groups of outpatients and retrospectively reviewed procedure records for conscious sedation and complications. Patients were divided into Group One (received sedative/amnesic diazepam), and Group Two, (received amnesic/sedative, midazolam and analgesic fentanyl). RESULTS All enteroclyses were successfully completed; there were no hospital admissions due to complications. In Group One (n=106), mean dose of diazepam was 12.7 mg. 25% had oxygen desaturation (n=25), and post-procedure vomiting without aspiration (n=1). 56% of outpatients completed phone surveys, and 68% recalled procedural discomfort. In Group Two (n=45), mean doses were 3.9 mg midazolam and 108 mcg fentanyl. 31% had desaturation (n=13), and post-procedure vomiting without aspiration (n=1). 87% had only a vague recall of the procedure or of any discomfort. CONCLUSION A combination of amnesic and fentanyl prevented the recall of discomfort of nasoenteric intubation and infusion in most patients who had enteroclysis compared to diazepam. Most of the patients would undergo the procedure again, if needed.

Abstract
Among the major innovations in radiology of the gastrointestinal (GI) system are the replacement of classic invasive diagnostic methods with noninvasive ones and the improvement in lesion characterization and staging of pancreatobiliary malignancies. Developments in imaging technology have led to many improvements in the field of diagnostic GI radiology. With its fast and thin-section scanning abilities, multidetector-row CT (MDCT) strengthens the place of CT as the most efficient tool to diagnose, characterize, and preoperatively stage pancreatic neoplasms. MR cholangiopancreatography has widely replaced endoscopic retrograde cholangiopancreatography in the diagnosis and staging of pancreatobiliary malignancies. MR imaging, using phased-array or endorectal coils, demonstrates local tumor invasion accurately in rectal cancers and thus allows an improved surgical planning. Virtual colonoscopy with MDCTs is an efficient screening method for colon cancer, and MDCT enterography is becoming the standard imaging technique for many small bowel disorders. The continuing developments in CT and MR technology will most probably further improve the accuracy of these and other imaging applications in the near future.

Abstract
The radiologic workup of patients with known or suspected small bowel obstruction and the timing of surgical intervention in this complex situation have undergone considerable changes over the past two decades. The diagnosis and treatment of small bowel obstruction, a common clinical condition often associated with signs and symptoms similar to those seen in other acute abdominal disorders, continue to evolve. This article examines the changes related to the use of imaging in the diagnosis and management of patients with this potentially dangerous problem and revisits pertinent controversies.

Abstract
As the primary method of investigating the small bowel, enteroclysis remains a technique in evolution. Technical refinements have made the examination faster to perform, better tolerated by patients, and easier to interpret. More recently, its essential principle of volume challenge has been combined with the tremendous advantage of CT cross-sectional imaging with multiplanar reformatting to give rise to the exciting new techniques of CT enteroclysis and MR enteroclysis (see separate reviews in this issue). Through improvements in methodology and advancements in technology, the future of enteroclysis looks bright indeed.

Abstract
Currently, CT-E is not recommended as the first-line examination in patients when mucosal detail is required. Double-contrast barium air enteroclysis has advantages in demonstrating small mucosal abnormalities. The authors find CT-E of value in the work-up of patients with symptoms of intermittent small bowel obstruction, particularly those with a history of prior abdominal surgery; in the further work-up of selected patients with high-grade obstruction in whom general surgeons prefer initial conservative management (immediate postoperative small bowel obstruction, patients with history of prior abdominal surgery for malignant tumor, history of radiation treatment, and possible internal extraintestinal fistulae); in looking for complications of small bowel Crohn's disease; and in the patient with unexplained anemia or gastrointestinal bleeding. In a series of patients who had both abdominal CT and barium enteroclysis done, each examination provided unique and complimentary diagnostic information. Because CT-E combines the advantages of both methods of examination, is it the optimum imaging work-up in the investigation of small bowel disease? Further research and clinical experience will define the precise role of CT-E in the investigation of small bowel disease. Experience with this method of examination is limited to a few institutions, performed by investigators with interest in small bowel diseases. The addition of cross-sectional display and multiplanar reformatting made possible by multidetector-row helical CT to enteral volume change and the use of multifunctional nasointestinal catheters make CT-E an important tool in the investigation of small bowel disease. Experience has shown the increased reliability of any method of examining the small bowel that challenges intestinal wall distensibility by fluid enteral volume infusion.
