Evaluation of Peripheral Muscle With Ultrassonografic of Critical Patients With Covid-19

Introduction: the length of hospital stay may be associated with factors such as the need for mechanical ventilation, severity of the underlying disease, infections, use of sedation and neuromuscular blockers. In this context, the new coronavirus (SARS-CoV-2) presents itself as a group of viruses that can cause acute respiratory syndromes with mild and severe symptoms, contributing to increased hospital stays and periods of immobility. Peripheral muscle measurement through ultrasound is a topic of growing interest in the assessment of critically ill patients. Currently, this tool has been shown to be able to assess muscle dimensions and morphology during hospitalization in the intensive care unit (ICU) and can be performed at the bedside, presenting itself as a reliable inter and intraobserver method. As this tool does not depend on patient collaboration and is a non-invasive method available in most ICUs, it can provide additional information to the physical examination and clinical impression. Objective: to evaluate the evolution of ultrasound pattern measurements in mechanically ventilated patients admitted to the ICU. Methods: prospective cohort study that will be carried out in the ICU of the Recife Women's Hospital, located in Recife - PE, with individuals of both genders, over 18 years old, under mechanical ventilation due to suspicion or confirmation of COVID- 19. To carry out this study, the measurement of the ultrasound pattern of peripheral muscles will be performed from admission to the ICU, with follow-up on the 3rd, 5th and 7th days under mechanical ventilation. The length of stay in the ICU and mechanical ventilation, mortality in this population will also be evaluated. Clinical, laboratory, oxygenation, ventilation, respiratory system mechanics data will also be analyzed. Data will be collected and archived for analysis, which considers differences between groups with p\<0.05. All ethical principles will be respected with either written Free and Consent Term by the patient or relatives at the intensive care phase or at the post ICU discharge phase. Expected results: to contribute to a more complete assessment of these patients, exploring outcomes such as survival, length of stay in the ICU and effects of immobility on peripheral muscle mass.
