Development and simultaneous application of multiple care protocols in critical care: amulticenter feasibility study

Objective: To test the feasibility of and interactions among three software-driven critical care protocols. Design: Prospective cohort study. Setting: Intensive care units in six European and American university hospitals. Patients: 174 cardiac surgery and 41 septic patients. Interventions: Application of software-driven protocols for cardiovascular management, sedation, and weaning during the first 7days of intensive care. Measurements and results: All protocols were used simultaneously in 85% of the cardiac surgery and 44% of the septic patients, and any one of the protocols was used for 73 and 44% of study duration, respectively. Protocol use was discontinued in 12% of patients by the treating clinician and in 6% for technical/administrative reasons. The number of protocol steps per unit of time was similar in the two diagnostic groups (n.s. for all protocols). Initial hemodynamic stability (a protocol target) was achieved in 26 ± 18 min (mean ± SD) in cardiac surgery and in 24 ± 18 min in septic patients. Sedation targets were reached in 2.4 ± 0.2 h in cardiac surgery and in 3.6 ± 0.2 h in septic patients. Weaning protocol was started in 164 (94%; 154 extubated) cardiac surgery and in 25 (60%; 9 extubated) septic patients. The median (interquartile range) time from starting weaning to extubation (a protocol target) was 89 min (range 44-154 min) for the cardiac surgery patients and 96 min (range 56-205 min) for the septic patients. Conclusions: Multiple software-driven treatment protocols can be simultaneously applied with high acceptance and rapid achievement of primary treatment goals. Time to reach these primary goals may provide aperformance indicato

Venous thromboembolism in critically Ill patients with COVID-19: Results of a screening study for deep vein thrombosis.

The rapid spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and coronavirus disease 2019 (COVID-19), has caused more than 3.9 million cases worldwide. Currently, there is great interest to assess venous thrombosis prevalence, diagnosis, prevention, and management in patients with COVID-19. To determine the prevalence of venous thromboembolism (VTE) in critically ill patients with COVID-19, using lower limbs venous ultrasonography screening. Beginning March 8, we enrolled 25 patients who were admitted to the intensive care unit (ICU) with confirmed SARS-CoV-2 infections. The presence of lower extremity deep vein thrombosis (DVT) was systematically assessed by ultrasonography between day 5 and 10 after admission. The data reported here are those available up to May 9, 2020. The mean (± standard deviation) age of the patients was 68 ± 11 years, and 64% were men. No patients had a history of VTE. During the ICU stay, 8 patients (32%) had a VTE; 6 (24%) a proximal DVT, and 5 (20%) a pulmonary embolism. The rate of symptomatic VTE was 24%, while 8% of patients had screen-detected DVT. Only those patients with a documented VTE received a therapeutic anticoagulant regimen. As of May 9, 2020, 5 patients had died (20%), 2 remained in the ICU (8%), and 18 were discharged (72%). In critically ill patients with SARS-CoV-2 infections, DVT screening at days 5-10 of admission yielded a 32% prevalence of VTE. Seventy-five percent of events occurred before screening. Earlier screening might be effective in optimizing care in ICU patients with COVID-19

Interet de la ventilation non-invasive aux soins intensifs. [Value of non-invasive ventilation in intensive care]

Noninvasive ventilation (NIV) refers to the delivery of mechanical ventilation using a nasal or facial mask. Compared to mechanical ventilation with endotracheal intubation, the occurence of complications, mainly infectious, is reduced by NIV. Reduction of respiratory workload and improvement of gas exchange are achieved with the use of NIV. In patients with exacerbations of chronic obstructive pulmonary disease (COPD), NIV reduces the need for endotracheal intubation, the length of ICU stay and the mortality. It is equally effective in acute cardiogenic pulmonary edema and for ventilatory weaning of patients with COPD. In selected groups of patients with acute hypoxemic respiratory failure, NIV diminishes the rate of endotracheal intubation and improves survival. The purpose of this article is to review the mechanisms, the technical aspects and the indications of NIV for the treatment of acute respiratory failure
