Abstract BACKGROUND: The wound healing process includes inflammation, proliferation, and remodelling phases, the main features of which are inflammation, neoangiogenesis, and epithelialization. Hyperbaric oxygen therapy (HBOT) is one modality postulated to improve wound healing. The objective of this study was to determine whether HBOT could improve selected features of burn wound healing in an experimental rabbit model. METHODS: Researchers conducted an experimental study […]...Read More

Systematic review: The safety and efficacy of hyperbaric oxygen therapy for inflammatory bowel disease

Summary Background Hyperbaric oxygen therapy (HBOT ) provides 100% oxygen under pressure, which increases tissue oxygen levels, relieves hypoxia and alters inflammatory pathways. Although there is experience using HBOT in Crohn’s disease and ulcerative colitis, the safety and overall efficacy of HBOT in inflammatory bowel disease (IBD ) is unknown. Aim To quantify the safety […]...Read More

Clinical Outcomes and Mortality Impact of Hyperbaric Oxygen Therapy in Patients With Carbon Monoxide Poisoning

Abstract Objective Carbon Monoxide (CO) poisoning affects 50,000 per year in the United States alone. Mortality is approximately 3% and up to 40% of survivors suffer from permanent neurocognitive and affective deficits. Hyperbaric oxygen therapy (HBO2) has shown benefit on reducing the long-term neurological sequelae of CO poisoning but has not demonstrated improved survival. The […]...Read More

Hyperbaric oxygen therapy facilitates healing of chronic foot ulcers in patients with diabetes

Abstract OBJECTIVE Chronic diabetic foot ulcers are a source of major concern for both patients and health care systems. The aim of this study was to evaluate the effect of hyperbaric oxygen therapy (HBOT) in the management of chronic diabetic foot ulcers. RESEARCH DESIGN AND METHODS The Hyperbaric Oxygen Therapy in Diabetics with Chronic Foot Ulcers (HODFU) […]...Read More

Hyperbaric oxygen protects against myocardial reperfusion injury via the inhibition of inflammation and the modulation of autophagy

Abstract Our previous study demonstrated that hyperbaric oxygen (HBO) preconditioning protected against myocardial ischemia reperfusion injury (MIRI) and improved myocardial infarction. However, HBO’s effect on MIRI-induced inflammation and autophagy remains unclear. In this study, we investigate the potential impact and underlying mechanism of HBO preconditioning on an MIRI-induced inflammatory response and autophagy using a ligation […]...Read More

Effects of hyperbaric oxygen therapy on neuropathic pain via mitophagy in microglia

Abstract Purpose Hyperbaric oxygen (HBO) therapy has been suggested to palliate neuropathic pain, but the mechanisms involved are not well understood. This study explored the involvement of microglial mitophagy via HBO relative to neuropathic pain therapy. Materials and methods A total of 80 male Sprague Dawley rats were randomly divided into two groups: a normal […]...Read More

Effects of hyperbaric oxygen and nerve growth factor on the long-term neural behavior of neonatal rats with hypoxic ischemic brain damage

Abstract Purpose: To evaluate the effects of HBO (Hyperbaric oxygen) and NGF (Nerve growth factor) on the long-term neural behavior of neonatal rats with HIBD (Neonatal hypoxic ischemic brain damage). Methods: The HIBD model was produced by ligating the right common carotid artery of 7 days old SD (Sprague-Dawley) rats followed by 8% O2 + […]...Read More

Combination of allopurinol and hyperbaric oxygen therapy: A new treatment in experimental acute necrotizing pancreatitis?

Abstract AIM: To investigate the individual and combined effects of allopurinol and hyperbaric oxygen (HBO) therapy on biochemical and histopathological changes, oxidative stress, and bacterial translocation (BT) in the experimental rat acute pancreatitis (AP). METHODS: Eighty-five Sprague-Dawley rats were included in the study. Fifteen of the eighty-five rats were used as controls (sham, GroupI). AP […]...Read More

Use of hyperbaric oxygen therapy (HBOT) in chronic diabetic wound – A randomised trial

Abstract Introduction: The purpose of this study was to investigate the effect of hyperbaric oxygen therapy (HBOT) towards diabetic foot ulcer (DFU) patients in addition to the standard wound care management. Methods: Fifty-eight diabetic patients with ulcers at Wagner Grade 2 and above involved in this study after presented at two study centres of tertiary […]...Read More

Hyperbaric oxygenation promotes neural stem cell proliferation and protects the learning and memory ability in neonatal hypoxic-ischemic brain damage

Abstract The aim of our study was to evaluate whether hyperbaric oxygenation (HBO) was an effective therapy for neonatal hypoxic ischemic brain damage (HIBD). Seven-day-old rat pups were divided into 3 groups: sham, hypoxia-ischemia (HI) control and HI-HBO group. HBO was administered for HI rats daily. The pathologic changes in brain tissues were observed by […]...Read More

Evaluation of the Occlusive Arterial Disease and Diabetic Angiopathy Treatment Effects by Hyperbaric Oxygenation

Abstract Introduction: One of the most severe complications of atherosclerosis is arterial occlusive disease (AOD) and with diabetic angiopathy (DA), is a common chronic problem in clinical practice worldwide. Hyperbaric oxygen (HBO) therapy is a therapeutic modality for solving all forms of hypoxia. Aim: To compare the treatment with HBO therapy in patients with AOD […]...Read More

A Pilot Study of Short-Duration Hyperbaric Oxygen Therapy to Improve HbA1c, Leukocyte, and Serum Creatinine in Patients with Diabetic Foot Ulcer Wagner 3-4

Abstract Objective. To evaluate the short-duration hyperbaric oxygen therapy (HBOT) can improve HbA1c levels, leukocyte count, and serum creatinine levels in patients with diabetic foot ulcer (DFU) Wagner 3-4. Methods. Blood samples from all DFU patients at Sanglah General Hospital, Denpasar, were taken for HbA1c, leukocyte, and serum creatinine test before debridement procedure, and the patients […]...Read More

The medical records of 200 patients treated with hyperbaric oxygen were reviewed from January to November 2013. The variables of the persons, clinical, […]...Read More

Revisiting the expanded use of hyperbaric oxygen therapy for treatment of resistant migraines

Abstract There are currently 13 indications approved by the U.S. Food and Drug Administration for use of hyperbaric oxygen therapy. The European Consensus Conference on Hyperbaric Medicine has 28 indications approved for its use. However, neither includes the use of hyperbaric oxygen therapy for neurological conditions such as migraines with aura. Recent research has made […]...Read More
