Video laryngoscopy versus direct laryngoscopy in achieving successful emergency endotracheal intubations: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Intubating a patient in an emergent setting presents significant challenges compared to planned intubation in an operating room. This study aims to compare video laryngoscopy versus direct laryngoscopy in achieving successful endotracheal intubation on the first attempt in emergency intubations, irrespective of the clinical setting.

METHODS

We systematically searched PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials from inception until 27 February 2023. We included only randomized controlled trials that included patients who had undergone emergent endotracheal intubation for any indication, regardless of the clinical setting. We used the Cochrane risk-of-bias assessment tool 2 (ROB2) to assess the included studies. We used the mean difference (MD) and risk ratio (RR), with the corresponding 95% confidence interval (CI), to pool the continuous and dichotomous variables, respectively.

RESULTS

Fourteen studies were included with a total of 2470 patients. The overall analysis favored video laryngoscopy over direct laryngoscopy in first-attempt success rate (RR = 1.09, 95% CI [1.02, 1.18], P = 0.02), first-attempt intubation time (MD =  - 6.92, 95% CI [- 12.86, - 0.99], P = 0.02), intubation difficulty score (MD =  - 0.62, 95% CI [- 0.86, - 0.37], P < 0.001), peri-intubation percentage of glottis opening (MD = 24.91, 95% CI [11.18, 38.64], P < 0.001), upper airway injuries (RR = 0.15, 95% CI [0.04, 0.56], P = 0.005), and esophageal intubation (RR = 0.37, 95% CI [0.15, 0.94], P = 0.04). However, no difference between the two groups was found regarding the overall intubation success rate (P > 0.05).

CONCLUSION

In emergency intubations, video laryngoscopy is preferred to direct laryngoscopy in achieving successful intubation on the first attempt and was associated with a lower incidence of complications.

Efficacy and safety of endoscopic submucosal dissection for colorectal dysplasia in patients with inflammatory bowel disease: a systematic review and meta-analysis

Background/Aims

In this meta-analysis, we studied the safety and efficacy of endoscopic submucosal dissection (ESD) for colorectal dysplasia in patients with inflammatory bowel disease (IBD).

Methods

Multiple databases were searched, and studies were retrieved based on pre-specified criteria until October 2022. The outcomes assessed were resection rates, procedural complications, local recurrence, metachronous tumors, and the need for surgery after ESD in IBD. Standard meta-analysis methods were followed using the random-effects model, and I2% was used to assess heterogeneity.

Results

Twelve studies comprising 291 dysplastic lesions in 274 patients were included with a median follow-up of 25 months. The pooled en-bloc resection, R0 resection, and curative resection rates were 92.5% (95% confidence interval [CI], 87.9%-95.4%; I2=0%), 81.5% (95% CI, 72.5%-88%; I2=43%), and 48.9% (95% CI, 32.1%-65.9%; I2=87%), respectively. The local recurrence rate was 3.9% (95% CI, 2%-7.5%; I2=0%). The pooled rates of bleeding and perforation were 7.7% (95% CI, 4.5%-13%; I2=10%) and 5.3% (95% CI, 3.1%-8.9%; I2=0%), respectively. The rates of metachronous recurrence and additional surgery following ESD were 10% (95% CI, 5.2%-18.2%; I2=55%) and 13% (95% CI, 8.5%-19.3%; I2=54%), respectively.

Conclusions

ESD is safe and effective for the resection of dysplastic lesions in IBD with an excellent pooled rate of en-bloc and R0 resection.

Medication Errors in Pediatric Emergency Departments: A Systematic Review and Recommendations for Enhancing Medication Safety

OBJECTIVE

This systematic review aims to investigate the prevalence, preventability, and severity of medication errors in pediatric emergency departments (P-EDs). It also aims to identify common types of medication errors, implicated medications, risk factors, and evaluate the effectiveness of interventions in preventing these errors.

METHODS

A systematic review analyzed 6 primary studies with sample sizes ranging from 96 to 5000 pediatric patients in P-EDs. The review followed Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines and included observational studies and randomized controlled trials involving patients aged 18 years and younger. Comprehensive searches in biomedical databases were conducted, and conflicts in record screening were resolved by a third reviewer using systematic review software.

RESULTS

Medication errors in P-EDs are prevalent, ranging from 10% to 15%, with dosing errors being the most common, accounting for 39% to 49% of reported errors. These errors primarily stem from inaccurate weight estimations or dosage miscalculations. Inadequate dosing frequency and documentation also contribute significantly to medication errors. Commonly implicated medications include acetaminophen, analgesics, corticosteroids, antibiotics, bronchodilators, and intravenous fluids. Most errors are categorized as insignificant/mild (51.7% to 94.5%) or moderate (47.5%). Risk factors associated with medication errors in P-EDs include less experienced physicians, severely ill patients, and weekend/specific-hour ordering. Human factors such as noncompliance with procedures and communication failures further contribute to medication errors. Interventions such as health information technology solutions like ParentLink and electronic medical alert systems, as well as structured ordering systems, have shown promise in reducing these errors, although their effectiveness varies.

CONCLUSIONS

Overall, this systematic review provides valuable insights into the complexity of medication errors in the P-ED, emphasizes the need for targeted interventions, and offers recommendations to enhance medication safety and reduce preventable errors in this critical health care setting.

Recurrent Multifocal Embolic Strokes in a 50-Year-Old Male: Unmasking Occult Squamous Cell Carcinoma

Recurrent cryptogenic embolic strokes pose a diagnostic challenge, often necessitating an extensive evaluation to determine the underlying cause. Cancer-related stroke is a frequently overlooked etiology, accounting for a substantial proportion of cryptogenic strokes. This case study underscores the importance of considering occult malignancies in patients with recurrent strokes of unknown origin and emphasizes the need for a comprehensive diagnostic workup to detect hidden malignancies. A 50-year-old male with a complex medical history presented with expressive aphasia and blurred vision resembling previous stroke episodes. Neurological examinations revealed right hemianopsia, paraphasia, and abnormal coordination. Neuroimaging studies showed multiple chronic infarctions, a large hemorrhagic infarction in the left posterior cerebral artery territory, and a small acute-to-subacute left parietal infarction. Due to the time of presentation and the presence of hemorrhagic transformation, the patient did not meet the criteria for intravenous tissue plasminogen activator administration. Given the recurrent nature of the strokes, an extensive evaluation was initiated to determine the underlying cause. Vascular imaging, including magnetic resonance angiography (MRA) of the head and neck and a CT angiogram, showed no significant stenosis. Vasculitis workup and cardiac evaluation yielded negative results. The blood workup was notable for elevated D-dimer levels. The involvement of multiple vascular territories and recurrent stroke despite adequate treatment and the absence of traditional risk factors for stroke raised a high clinical suspicion of occult malignancy. Further investigations led to the diagnosis of locally advanced squamous cell carcinoma (P16+), metastatic to the right neck lymph nodes (cTxN3M0). Although the primary source of cancer could not be identified, the P16+ status suggests the right tonsil or base of the tongue as the probable origin. Anticoagulation therapy was initiated, and the patient was scheduled for chemoradiation therapy. Although routine cancer investigation is not justified in ischemic strokes, the possibility of an occult malignancy should be considered in the presence of multifocal infarctions across different vascular territories with elevated D-dimer levels, particularly when traditional risk factors have been ruled out. A detailed physical exam can help localize the malignancy and early identification of occult malignancies can guide appropriate management strategies and help prevent future strokes. Further clinical trials are needed to establish optimal therapeutic approaches for preventing stroke recurrence in cancer-related strokes.

The effect of Medicaid payer status on patient outcomes following repair of massive rotator cuff tears

BACKGROUND

The influence of socioeconomic status and insurance type has not been studied extensively for RCR, particularly not in the high risk massive RCT population. The purpose of this study is to identify relationships between Medicaid payer status and patient outcomes following massive RCR.

METHODS

A retrospective review of shoulder surgery database identified 29 patients undergoing massive rotator cuff repair. Patients were stratified based on insurance type into two cohorts, Medicaid (14 patients) and non-Medicaid (15 patients). Missed routine follow-up appointments and comorbidities were recorded and compared between groups. Group comparisons were made for pre- and postoperative patient-reported and functional outcomes. Outcome scores included American Shoulder and Elbow Shoulder Score (ASES), the Penn Shoulder Score, and the Subjective Shoulder Value (SSV). A p value of < 0.05 was considered significant for all statistical analyses.

RESULTS

Medicaid patients were on average 7.1 years younger than non-Medicaid patients (49.8 vs. 56.9 years, respectively), and remaining demographics were comparable between groups. Preoperative patient-reported outcomes were only significantly different for ASES and ASES pain (p = 0.010, 0.037). There was excellent average improvement for Medicaid patients but no significant differences compared to non-Medicaid patients for ASES (p = 0.630), PENN scores (p = 0.395), and SSV (p = 0.198). Medicaid patients also had a higher number of missed and canceled appointments (28%) compared to non-Medicaid patients (18%).

CONCLUSION

Medicaid coverage will expand to millions of uninsured Americans under current healthcare reform. Medicaid patients with massive RCT appear to significantly improve with surgical treatment.
