[Hyperbaric therapy and diving medicine - hyperbaric therapy part 1: evidence-based emergency care].

Hyperbaric oxygen therapy (HBOT), i. e. breathing pure oxygen at elevated ambient pressure, remains the gold standard of care in treating air or gas embolism and decompression illness. Guidelines are less clear on the value of HBOT in acute management of carbon monoxide (CO) poisoning or clostridial necrosis. To evaluate the evidence of clinical efficacy of HBOT we performed a systematic literature review. Part 1 assesses acute indications such as air or gas embolism, decompression sickness, CO-poisoning, clostridialmyonecrosis, necrotizing problem wounds, acute traumatic wounds and arterial retinal occlusion. Part 2 discusses further uses of HBOT as adjuvant treatment and highlights problems in assessing the value of HBOT using evidence-based medicine criteria. © Georg Thieme Verlag Stuttgart · New York.
