Self Assessment 1. You are asked to assess a 42-year-old woman who requires an emergency extensor tendon repair to her left hand. There is no neurovascular deficit. She is 158cm tall and weighs 102kg. She last ate 2 hours ago. What factors will you especially need to consider in her pre-assessment? 2. A 55-year-old man with a BMI of 37 is having an anterior resection for colon cancer. Twenty minutes into the case you notice his oxygen saturations are falling and are now 88% despite FiO2 0.5. What actions can you take to improve his oxygenation? 3. A 65-year-old woman with a BMI of 41 is 24 hours post an elective total knee replacement. She has been given intramuscular morphine 2 hourly overnight. She is hypoxic with a SpO2 of 87% on room air. Her respiratory rate is 8 breaths per minute. What is your diagnosis and action plan?
