Clinical research has produced a continuous stream of evidence-based guidelines to guide practice in obstetrics. The guidelines are often widely scattered: this book brings together the essential guidelines in one comprehensive resource. The primary focus is on the Royal College of Obstetricians and Gynaecologists and other UK national guidelines; however, many chapters contain a ‘Guideline Comparator’ box carrying information from important international guidelines. Where there are no UK guidelines, information based on international guidelines is provided; where any guidelines do not exist, available evidence and accepted norms of practice based on expert opinion are detailed. Several chapters also contain a ‘what not to do’ box, which should act as a source of rich debate. To assist those studying for postgraduate examinations – such as MRCOG – the information is presented in schematic flowcharts, representing a step-by-step method of approaching clinical problems and providing an easy-to-use learning resource.
