This book presents further aspects of critical debate in clinical practice. Proposers and opposers of strongly held viewpoints put forward their cases in order to stimulate discussion and ideas for further investigation in obstetric anaesthesia, and ultimately, to increase the safety of both mother and fetus. This second volume includes seven new controversies, plus an update on how and if the controversies presented in the first volume have been resolved. The book is designed as an easy means for anaesthetists in training to familiarize themselves with both the arguments as well as the literature which are background to the controversies themselves.
