Abstract:
Obesity is a chronic disease characterised by the presence of excessive body fat that increases the risk of health problems. Traditionally, the administration of TIVA and TCI in the obese has been done using dose schemes extrapolated from non-obese patients. The use of such schemes has proven inadequate in the obese and they are commonly associated with overdose.[1,2] Dosing strategies of IV anaesthetics in heavy weight patients requires approaches that differ from those used in lean patients due to physiological and pharmacological changes associated with obesity.[3] This chapter is intended to be a practical guide for anaesthetists who wish to undertake TIVA and TCI in obese patients.
