Abstract The perioperative anaesthetic management of a case COVID-19 pneumonia with multiple systemic comorbidities, posted for unilateral below knee amputation and debridement hand, poses uniquely challenging scenario the anaesthesiologist. We hereby report such which was managed successfully using ultrasound-guided popliteal wrist block along use high flow nasal cannula, incentive spirometry ...

BACKGROUND The fraction of inspired oxygen (F(IO(2))) is quoted for different oxygen delivery systems, but variations in inspiratory flow and tidal volume make precise measurement difficult. We developed a reliable method of measuring the effective F(IO(2)) in patients receiving supplemental oxygen. METHODS Ten subjects with chronic hypoxemia breathed through a mouthpiece with a sampling prob...

The efficiency of two patient-dependent, variable performance techniques of oxygen therapy in relieving hypoxaemia after upper abdominal surgery was compared. A high-flow system delivered a humidified mixture of oxygen 2 litre min-1 and air 13 litre min-1 through a cannula inserted into the anterior nares. The low-flow system delivered 2 litre min-1 of dry oxygen into the nasopharynx through a ...
