Think before placing a nasogastric tube!
Multiple articles which discussed complications of NGT placement were included in this integrative review, with the majority (n=67) publishing results in English. The authors categorized adverse events into two broad categories:
1) Mechanical adverse events - including respiratory, esophageal, and pharyngeal complications, obstructed tube, intestinal and intracranial (!) perforation, and tube withdrawal
-The largest cohort (n=44) was respiratory, with displacement or placement of tube to the respiratory tract
2) Others - pressure injury and misconnection
-One study showed pressure related injury in 25%, and 5 articles discussed complications of misconnection (including extravasation of gastric fluids and inadvertent connection to central venous catheters)
16 of the 69 studies reported death as a consequence of improper placement.
One big takeaway: there is no universally accepted standard for verificaiton of tube placement. Xray is considered to be *most* accurate. Tubes should also be checked periodically and depth should be marked. Evidence-based guidelines need to be developed to improve patient safety, outcomes, and quality of care.

Keywords: acute diverticulitis (PubMed Search)
Diverticular disease is a common condition, with 60% of individuals over age 80 and 30% of those over age 45 (!) having diverticula. Recent estimates show that 10-25% of this subset with suffer at least one episode of acute diverticulitis in their lifetime. Fortunately, the majority of these cases are uncomplicated. This study provides evidence that outpatient treatment of acute diverticulitis is reasonable.
The DINAMO study was a multicenter randomized open-label non-inferiority trial evaluating the utility of antitbiotics in uncomplicated diverticulitis. The study included adult patients with uncomplicated diverticulitis without significant comorbities. The diagnosis was based on modified Neff classification with patients with a mNeff of 0 being included. Eligible patients were randomized to one of two treatment groups:
1) 600 mg ibuprofen q 8 h alternating with 1000 mg of acetaminophen q 8 h x7 d (Exerimental arm) OR
2) 875/125 mg amoxicillin/clavulanate q 8 h x 7 d in addition to the above (Control arm)
Outcomes of interest and Results:
Any patients who returned to the hospital underwent repeat CT. Primary of outcome of interest was admission to the hospital on revisit, with secondary outcomes being revisit itself, follow up, pain control, and recovery
There was no statistically significant difference in any of these (for numbers, please refer to article 1 linked below); further, no patients required emergency surgery.
There is a low likelihood ot treatment failure when antibiotics are avoided in acute uncomplicated diverticulitis. This study finds this treatment regimen ot be noninferior to antibiotic treatment in terms of hospital admission, revisit rates, and recovery. Consider this treatment regimen in eligible patients.
Keywords: Appendicitis (PubMed Search)
In recent years, there has been an uptick in non-operative management of acute appendicitis. This study examins outcomes in older patients (>65 years old).
The study authors evaluated retrospective data and included 474845 patients in the US with acute uncomplicated appendicitis betwen 10/2021 and 04/2022. All participants survived at least 24 hours postoperatively and none carried a diagnosis of inflammatory bowel disease; there were 43,846 patients treated nonoperatively and 430,999 who underwent appendectomy. The primary outcome was incidence of post-treatment complications, with secondary outcomes of mortality, length of stay, and inpatient costs.
In patients 65+, there was a 3.72% decrease in risk of complications, 1.82% increase in mortality, and increased LOS and costs.
Ultimately, operative management of acute appendicits was associated with reduced mortality, length of stay, and costs across all adult patients. While nonoperative management remains an option in the treatment of acute appendicits, surgical management continues to be the accepted standard.

Keywords: cannabis hyperemesis syndrome (PubMed Search)
Bottom Line: With the increasing acceptance and legalization of marijuana and its derivatives, emergency departments have seen an increase in patients with cannabis hyperemesis syndrome (CHS). In this patient population, when other pathologies have been excluded, consider droperidol (0.625 mg – 2.5 mg) or haloperidol (0.05 mg/kg or 0.1 mg/kg) for management of symptoms.
Two separate articles were reviewed for this pearl. One is a systematic review of existing literature, and the other is a randomized controlled trial.
The systematic review examined 17 existing studies, including case reports, RCTs, retrospective studies, and other systematic reviews. This included adults aged 18-85 who were using recreational or medicinal cannabinoids. There was a consensus that cessation of cannabinoid use is the best way to alleviate symptoms of CHS. Other options discussed include:
As mentioned above, the HaVOC study examined various doses of haloperidol versus odansetron. This randomized controlled trial was triple blinded and had three groups: haloperidol 0.05 mg/kg or 0.1 mg/kg or odansetron 8 mg IV. The outcome of interest was reduction in abdominal pain and nausea at two hours after treatment. Either dose of haloperidol was found to be superior to odansetron, with improvements in pain and nausea (54% versus 29%; 95% CI -16% to 59%), and less use of rescue antiemetics (31% versus 59%, with 95% CI -61% to 13%). Haloperidol also resulted in shorter ED length of stay (3.1 h vs 5.6 h, 95% CI 0.1-5.0 h, p=0.03). However, 2 patients in the high dose haloperidol group had dystonic reactions precipitating return visits. The study does not specifically discuss differences in outcomes between the high and lower dose haloperidol groups.
Neither paper discussed the best alternatives when QTc prolongation is of concern. Clinicians should use their best judgment and the available information when deciding on a treatment option.
