Metabolism

Abstract

This chapter tells you how homeostasis in the body is achieved. Contributing factors such as stress, hormones, and the automatic nervous system are integrated into the discussion in a thoughtful way. The problem of cold postoperative patients is thoroughly referenced to modern investigation. Diabetes, how surgery destabilizes diabetics, and how to use insulin is explained. Malignant hyperthermia, thyroid storm, and acid–base disorders are all problems that can occur in the recovery room and guidelines for the management of these patients are outlined. Hydrogen ions affect haemoglobin and biochemical reactions and can cause acidosis and alkalosis—this chapter outlines how to interpret the blood gas results. How to distinguish between respiratory and metabolic causes of acid–base disorders is simply and clearly explained.
