OBJECTIVE In the post-sternotomy mediastinitis patients, Staphylococcus aureus is the pathogenic microorganism encountered most often. In our study, we aimed to determine the efficacy of antibiotic treatment with vancomycin and tigecycline, alone or in combination with hyperbaric oxygen treatment, on bacterial elimination in experimental S. aureus mediastinitis. METHODS Forty-nine adult femal...

This study examined the effect of exposures to hyperbaric oxygen on the development of the edema and necrosis of muscle that are associated with compartment syndromes that are complicated by hemorrhagic hypotension. A compartment syndrome (twenty millimeters of mercury for six hours) was induced by infusion of autologous plasma in the anterolateral compartment of the left hind limb of seven ane...

PURPOSE Hemorrhagic cystitis is a recognized possible side effect of therapeutic radiation administered for a variety of pelvic malignancies. Patients may experience pain, bleeding and clot retention. Various palliative treatments, including instillation of alum, silver nitrate and formalin, may be unsuccessful in alleviating patient symptoms. Hyperbaric oxygen therapy is often used to treat po...

To determine hyperbaric oxygen (HBO2) treatment practices for osteoradionecrosis (ORN) of the mandible in North America, we surveyed hyperbaric facilities listed in the 1998 UHMS Chamber Directory. A survey response rate of 99.7% was achieved. Among the 316 facilities listed, 280 treat or would treat mandibular ORN with HBO2. Twelve different hyperbaric treatment protocols for the condition wer...

Oxygen is critical for optimal bone regeneration. While axolotls and salamanders have retained the ability to regenerate whole limbs, mammalian regeneration is restricted to the distal tip of the digit (P3) in mice, primates, and humans. Our previous study revealed the oxygen microenvironment during regeneration is dynamic and temporally influential in building and degrading bone. Given that re...

Hyperbaric exposure with high oxygen concentration inhibits a growth-related increase in the glucose and insulin of diabetic rats. In this study, 5-week-old diabetic Goto-Kakizaki rats were exposed to a hyperbaric environment (1.25 atmospheric pressure) with a high oxygen concentration (36%) for 6 h daily. Fiber type distributions and oxidative enzyme activities in the fast-twitch plantaris mus...

For a large number of ischaemic, infective, inflammatory or traumatic conditions, hyperbaric oxygen therapy is either the only treatment or an adjunct that significantly reduces morbidity and mortality. The primary aim of this review is to identify clinical conditions treated in a paediatric population referred to Australian hyperbaric units. Secondary aims are to describe outcomes of treatment...

The actions of oxygen in the body are extremely complex, and are also involved in various signalling pathways. Hyperbaric oxygen is known to contribute to the improvement of conditions where tissue circulation is suboptimal, and has considerable usage in different treatment protocols and experimental investigations. However, the precise mechanism by which hyperbaric oxygen changes the functioni...

Searching MEDLINE and government databases (e.g. the Defense Technical Information Centre, the National Technical Information Service, and the Undersea and Hyperbaric Medical Society database) were searched using the terms 'carbon monoxide', 'carbon monoxide poisoning', 'delayed neurologic sequelae', 'hyperbaric oxygen', 'normobaric oxygen' and 'hyperbaric therapy'. Bibliographies of retrieved ...

PURPOSE To research the hyperbaric oxygen therapy effects on rats' livers and spleens. METHODS 30 adult male Hotzman rats were used, being randomly distributed, by raffle, into 2 groups of 15 animals each: group 1 - control; group 2 - hyperbaric oxygen therapy. Group-2 animals underwent hyperbaric oxygen therapy for 120 minutes daily, 90 minutes of which were under pressure of 2.5 atmospheres...
