Despite increasing interest in intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) as causes of significant morbidity and mortality among the critically ill, unanswered questions cloud the understanding of the pathophysiology of these conditions: • Are IAH and ACS synonymous? • What are the ideal methods of measuring and lowering intra-abdominal pressure (IAP)? • When should we think of IAH? • Can IAH be prevented? • What level of IAP requires abdominal decompression? Written by two experts in critical care and IAP, Intra-Abdominal Hypertension is a distillation of the current literature and furthers the understanding of these complex critical conditions. Using a step-by-step approach and illustrative figures, this clinical handbook presents a concise overview of consensus definitions, measurement methods, organ assessment and treatment options. Intra-Abdominal Hypertension is essential reading for all members of the intensive care multidisciplinary team, including experienced and junior physicians, anesthetists and nurses.
