Trauma is a major cause of maternal death in pregnancy. The pregnant woman who has been involved in an episode leading to her arrival in an accident and emergency department presents with specific problems that often require specialist attention. The correct initial management of such patients should not be beyond the capabilities of an average trauma team and such management is clearly taught as part of the Advanced Trauma Life Support course now available in the UK. This review outlines the physiological changes associated with pregnancy that become important during resuscitation and definitive care. It discusses the presentation and management of specific problems, and the safety--or otherwise--of commonly administered drugs. Only the initial resuscitation of the patient is considered; specialist obstetric care is beyond the scope of the article.
