Epidemiologic features and outcomes associated with caustic ingestion among adults admitted in intensive care unit from 2013 to 2019: a French national observational study.

PURPOSE: Caustic ingestion is a potential life-threatening condition associated with high morbidity and mortality. Data on patients admitted to Intensive Care Unit (ICU) for severe caustic ingestion are lacking. We aimed to describing epidemiological features and outcomes of patients admitted to ICU for caustic ingestion in France. METHODS: In a retrospective, observational, and multicenter study, data from the national French Programme de Médicalisation des Systèmes d'Informations (PMSI) database were analysed from 2013 to 2019. In-hospital mortality rate (primary outcome) and in-ICU complications (secondary outcomes) were reported and analysed. RESULTS: 569 patients (289 males (50.8%), with median age of 49 years [interquartile (26-62)] were admitted in 65 French ICU for severe caustic ingestion. Five hundred and thirteen patients (90%) were admitted for intentional caustic ingestion. The median length of stay in ICU was 14.0 [4.0-31.0] days. In-hospital mortality occurred in 56 patients (9.8%). In multivariate analysis, age and simplified acute physiology score II were associated with in-hospital mortality age of 40-59 years [OR = 15.3 (2.0-115.3)], age of 60-79 years [OR = 23.6 (3.1-182.5)], and age > 80 years [OR = 37.0 (4.2-328.6)] and SAPS 2 score [OR = 1.0018 (1.003-1.033), p < 0.001]. During ICU stay, 423 complications (74%) were reported in 505 patients (89%). Infectious (244 (42.9%)), respiratory (207 (36.4%)), surgical 62 (10.9%), haemorrhagic (64 (11.2%)) and thrombo-embolic and (35 (6.2%)) complications were the most frequently reported during ICU stay. CONCLUSION: ICU admission for severe caustic ingestion is associated with 9.8% mortality and 74% complications. Age > 40 years and SAPS 2 score were independently associated with mortality.

How to improve the efficiency and the safety of real-time ultrasound-guided central venous catheterization in 2023: a narrative review.

Central venous catheterization (CVC) is a frequent procedure, practiced by intensivists, anesthesiologists and advanced practice nurses in intensive care units and operative rooms. To reduce CVC-associated morbidity, it is essential to strive for best practices, based on the latest evidence. This narrative review aims to synthesize current knowledge on evidence-based best practices for CVC that improve the use and feasibility of real-time ultrasound-guided insertion procedures. Optimization of the vein puncture technique and the development of new technologies are discussed to reinforce the use of the subclavian vein catheterization as first choice. The search for alternative site of insertions, without increasing infectious and thrombotic risks, deserves further research.

Intensive Care Unit activity in France from the national database between 2013 and 2019: More critically ill patients, shorter stay and lower mortality rate.

BACKGROUND: Knowledge of the occurrence and outcome of admissions to Intensive Care Units (ICU) over time is important to inform healthcare services planning. This observational study aims at describing the activity of French ICUs between 2013 and 2019. METHODS: Patient admission characteristics, organ dysfunction scores, therapies, ICU and hospital lengths of stay and case fatality were collected from the French National Hospital Database (population-based cohort). Logistic regression models were developed to investigate the association between age, sex, SAPS II, organ failure, and year of care on in-ICU case fatality. FINDINGS: Among 1,594,801 ICU admissions, the yearly ICU admission increased from 3.3 to 3.5 per year per 1000 inhabitants (bed occupancy rate between 83.4 and 84.3%). The mean admission SAPS II was 42 ± 22, with a gradual annual increase. The median lengths of stay in ICU and in hospital were 3 (interquartile range (IQR) = [1-7]) and 11 days (IQR = [6-21]), respectively, with a progressive decrease over time. The in-ICU and hospital mortality case fatalities decreased from 18.0% to 17.1% and from 21.1% to 19.9% between 2013 and 2019, respectively. Male sex, age, SAPS II score, and the occurrence of any organ failure were associated with a higher case fatality rate. After adjustment on age, sex, SAPS II and organ failure, in-ICU case fatality decreased in 2019 as compared to 2013 (adjusted Odds Ratio = 0.87 [95% confidence interval, 0.85-0.89]). INTERPRETATION: During the study, an increasing incidence of ICU admission was associated with higher severity of illness but lower in-ICU case fatality.

Axillary vein catheterization using ultrasound guidance: A prospective randomized cross-over controlled simulation comparing standard ultrasound and new needle-pilot device.

BACKGROUND: Real-time ultrasound (US) guidance facilitates central venous catheterization in intensive care unit (ICU). New magnetic needle-pilot devices could improve efficiency and safety of central venous catheterization. This simulation trial was aimed at comparing venipuncture with a new needle-pilot device to conventional US technique. METHODS: In a prospective, randomized, simulation trial, 51 ICU physicians and residents cannulated the right axillary vein of a human torso mannequin with standard US guidance and with a needle-pilot system, in a randomized order. The primary outcome was the time from skin puncture to successful venous cannulation. The secondary outcomes were the number of skin punctures, the number of posterior wall puncture of the axillary vein, the number of arterial punctures, the number of needle redirections, the failure rate, and the operator comfort. RESULTS: Time to successful cannulation was shorter with needle-pilot US-guided technique (22 s (interquartile range (IQR) = 16-42) vs 25 s (IQR = 19-128); median of difference (MOD) = -9 s (95%-confidence interval (CI) -5, -22), p < 0.001). The rates of skin punctures, posterior wall puncture of axillary vein, and needle redirections were also lower (p < 0.01). Comfort was higher in needle-pilot US-guided group on a 11-points numeric scale (8 (IQR = 8-9) vs 6 (IQR = 6-8), p < 0.001). CONCLUSIONS: In a simulation model, US-guided axillary vein catheterization with a needle-pilot device was associated with a shorter time of successful cannulation and a decrease in numbers of skin punctures and complications. The results plea for investigating clinical performance of this new device.

High success rates of ultrasound-guided distal internal jugular vein and axillary vein approaches for central venous catheterization: A randomized controlled open-label pilot trial.

BACKGROUND: Ultrasound (US)-guided axillary vein (AV) catheterization has been considered as the preferred site of insertion to minimize catheter-related infections. Given its difficulty of realization, internal jugular vein (IJV) access remains, thus, the first choice of catheter insertion site. This descriptive study was aimed to assess the success and complication rates of in-plane short axis approach of IJV in the lower neck and the AV approach under US-guidance. METHODS: In a prospective randomized controlled open-label pilot trial, all patients requiring central venous catheterization (CVC) in intensive care unit or operating room were randomly assigned to low IJV or AV groups. The primary objective was to estimate the overall success rate of both approaches. The secondary objectives were immediate complication rates, procedure durations, success rate after the first puncture, late complication rates (i.e., thrombosis, catheter colonization, and catheter-related infections), and nurse satisfaction regarding insertion site dressings. RESULTS: One hundred and seventy-three out of two hundred and ten included patients were fully analyzed (90 and 83 in the IJV and AV approach groups, respectively). Overall success rates for IJV and AV sites were 96% (95% confidence interval (CI) [90-99]) and 89% (95% CI [81-94]) respectively. First puncture success rates were 90% and 80% respectively. The median overall procedure duration from US pre-procedural screening to guidewire insertion was 8 and 10 min in IJV and AV groups. Overall immediate complications rates for IJV and AV sites were 11.6% and 14.6%, respectively. Incidence of catheter colonization were 7.9% and 6.8% and catheter-related infection rate were 2.6% and 0%, respectively. CONCLUSION: In this pilot study, US-guided low IJV and AV approaches are safe and efficient techniques for CVC insertion associated with high success and low complications rates. Duration for guidewire insertion seemed to be shorter in the short axis in-plane IJV approach. It provides the basis for a future randomized trial comparing these two approaches.
