Effects of Awake Prone Positioning in Non-intubated Spontaneously Breathing COVID-19 Patients Requiring High Flow Oxygen Therapy in High Dependency Unit (HDU): An Observational Study.

Background And Aims: Prone positioning increases oxygenation by recruiting dorsal lung regions and draining airway secretions and improves gas exchange and survival in ARDS. We describe the efficacy of prone positioning in awake non-intubated spontaneously breathing COVID-19 positive patients with hypoxemic acute respiratory failure.

Methods: We studied 26 awake non-intubated spontaneously breathing patients with hypoxemic respiratory failure treated with prone positioning.

Comparative evaluation of midazolam, dexmedetomidine, and propofol as Intensive Care Unit sedatives in postoperative electively ventilated eclamptic patients.

Background And Aims: Eclampsia is a common hypertensive disorder of pregnancy and treatment often includes termination of pregnancy with elective postoperative mechanical ventilation. The present study was aimed to compare midazolam, propofol, and dexmedetomidine for sedation and antihypertensive requirements of such patients admitted to Intensive Care Unit (ICU) after termination of pregnancy.

Material And Methods: A total of ninety eclamptic patients administered general anesthesia for the termination of pregnancy through cesarean section and who also required postoperative ventilation were taken up for the study and were randomly allocated into three groups.
