Deep Sedation

Severe COVID-19 may predispose to both venous and arterial thrombosis. We describe a patient with acute ischaemic stroke while suffering from COVID-19 and respiratory failure, necessitating mechanical ventilation. Deep sedation may delay diagnosis.

Mechanical ventilation is a necessary intervention for patients with acute lung injury. However, mechanical ventilation can propagate acute lung injury and increase systemic inflammation. The exposure to >21% oxygen is often associated with mechanical ventilation yet has not been examined within the context of lung stretch. We hypothesized that mice exposed to >90% oxygen will be more susceptible to the deleterious effects of high stretch mechanical ventilation. C57B1/6 mice were randomized into 48-h exposure of 21 or >90% oxygen; mice were then killed, and isolated lungs were randomized into a nonstretch or an ex vivo, high-stretch mechanical ventilation group. Lungs were assessed for compliance and lavaged for surfactant analysis, and cytokine measurements or lungs were homogenized for surfactant-associated protein analysis. Mice exposed to >90% oxygen + stretch had significantly lower compliance, altered pulmonary surfactant, and increased inflammatory cytokines compared with all other groups. Our conclusion is that 48 h of >90% oxygen and high-stretch mechanical ventilation deleteriously affect lung function to a greater degree than stretch alone.

Abstract Background: Until now, transfusion-related acute lung injury (TRALI) has been considered to be the leading cause of blood transfusion-related diseases and death. And there is no clinically effective treatment plan for TRALI. The aim of this study was to systematically summarize the literature on risk factors for TRALI in critical patients. Methods: Electronic searches (up to March 2020) were performed in the Cochrane Library, Web of Knowledge, Embase, and PubMed databases. We included studies reporting on the risk factors of TRALI for critical patients and extracted the risk factors. Finally, third studies met the inclusion criteria. Results: We summarized and analyzed the potential risk factors of TRALI for critical patients in 13 existing studies. The host-related factors were age (odds ratio (OR) [95% confidence interval] = 1.16 [1.08-1.24]), sex (OR = 1.26 [1.16-1.38]), tobacco use status (OR = 3.82 [1.91-7.65]), chronic alcohol abuse (OR = 3.82 [2.97-26.83]), fluid balance (OR = 1.24 [1.08-1.42]), shock before transfusion (OR = 4.41 [2.38-8.20]), and ASA score of the recipients (OR = 2.72 [1.43-5.16]). The transfusion-related factors were the number of transfusions (OR = 1.40 [1.14-1.72]) and fresh frozen plasma (FFP) units (OR = 1.21 [1.01-1.46]). The device-related factor was mechanical ventilation (OR = 4.13 [2.20-7.76]). Conclusions: The risk factors for TRALI in this study included age, sex, tobacco use, chronic alcohol abuse, fluid balance, shock before transfusion, ASA score, number of transfusions, FFP units and mechanical ventilation. Our study suggests that host-related risk factors play a more important role in the occurrence and development of TRALI than blood transfusion-related risk factors.

Ventilator Induced Lung Injury

Invasive and noninvasive ventilation are important tools in the clinician’s armamentarium for managing acute respiratory failure. Although these modalities do not treat the underlying disease, they can provide the necessary oxygenation and ventilatory support until the causal pathology resolves. Care must be taken as even appropriate application can cause harm. Knowledge of pulmonary mechanics, appreciation of the basic machine settings, and an understanding of how common and advanced modes function allows the clinician to optimally tailor support to the patient while limiting iatrogenic injury. This second chapter reviews indications for mechanical ventilation, routine management, troubleshooting, and liberation from mechanical ventilation This review contains 6 figures, 7 tables and 60 references Keywords: Mechanical ventilation, lung protective ventilation, sedation, ventilator-induced lung injury, liberation from mechanical ventilation
