Fascia Iliaca Block in Hip and Femur Fractures to Reduce Opioid Use.

BACKGROUND: Fascia iliaca compartment block (FICB) has become a keystone technique for acute pain management in patients with hip and proximal femur fractures. OBJECTIVES: To demonstrate that administering FICB preoperatively to patients with hip or proximal femur fractures in the emergency department (ED) is likely to reduce opioid use and related complications, and to decrease hospital length of stay (LOS). METHODS: An unblinded study of adult patients with hip and proximal femur fractures who consented to receive an FICB with 30 cc of bupivacaine with epinephrine administered in the ED. We compared this group with a contemporaneous group of controls who only received systemic opioids. Over the course of approximately 6 months, main outcome measured between the two groups was amount of morphine equivalents given from block administration until 8 h after. We also compared complications such as delirium, constipation, and bleeding rates (oozing from injection site or hematoma formation). RESULTS: A total of 166 patients with hip and proximal femur fractures from August 12, 2018 to April 25, 2021; 81 received FICB plus systemic opioids, and 85 received only systemic opioids. Among the FICB group, morphine equivalents were reduced by 0.6 mg/h with no significant difference in LOS. A statistically significant difference in opioid-related adverse outcomes was found between the anticoagulated group vs. the no anticoagulation group. CONCLUSIONS: FICB is a safe and effective preoperative technique for initial pain management in patients with hip and proximal femur fractures, as it can also be used with additional systemic opioids. FICB administration may reduce systemic opioid use preoperatively, thus reducing opioid-related adverse effects with no significant impact on hospital LOS.

Association of Obesity With COVID-19 Severity and Mortality: An Updated Systemic Review, Meta-Analysis, and Meta-Regression.

Background: Obesity affects the course of critical illnesses. We aimed to estimate the association of obesity with the severity and mortality in coronavirus disease 2019 (COVID-19) patients. Data Sources: A systematic search was conducted from the inception of the COVID-19 pandemic through to 13 October 2021, on databases including Medline (PubMed), Embase, Science Web, and Cochrane Central Controlled Trials Registry. Preprint servers such as BioRxiv, MedRxiv, ChemRxiv, and SSRN were also scanned. Study Selection and Data Extraction: Full-length articles focusing on the association of obesity and outcome in COVID-19 patients were included. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used for study selection and data extraction. Our Population of interest were COVID-19 positive patients, obesity is our Intervention/Exposure point, Comparators are Non-obese vs obese patients The chief outcome of the study was the severity of the confirmed COVID-19 positive hospitalized patients in terms of admission to the intensive care unit (ICU) or the requirement of invasive mechanical ventilation/intubation with obesity. All-cause mortality in COVID-19 positive hospitalized patients with obesity was the secondary outcome of the study. Results: In total, 3,140,413 patients from 167 studies were included in the study. Obesity was associated with an increased risk of severe disease (RR=1.52, 95% CI 1.41-1.63, p<0.001, I2 = 97%). Similarly, high mortality was observed in obese patients (RR=1.09, 95% CI 1.02-1.16, p=0.006, I2 = 97%). In multivariate meta-regression on severity, the covariate of the female gender, pulmonary disease, diabetes, older age, cardiovascular diseases, and hypertension was found to be significant and explained R2 = 40% of the between-study heterogeneity for severity. The aforementioned covariates were found to be significant for mortality as well, and these covariates collectively explained R2 = 50% of the between-study variability for mortality. Conclusions: Our findings suggest that obesity is significantly associated with increased severity and higher mortality among COVID-19 patients. Therefore, the inclusion of obesity or its surrogate body mass index in prognostic scores and improvement of guidelines for patient care management is recommended.
