ABSTRACT
Hyperbaric medicine is the fascinating use of barometric pressure for delivering increased oxygen dissolved in plasma to body tissues. Hyperbaric oxygen therapy (HOT) or hyperbaric oxygen (HBO) involves intermittent inhalation of 100% oxygen under a pressure exceeding that of the atmosphere, that is greater than 1 atmosphere absolute (ATA). Therapy is given in special therapeutic chambers which were earlier used primarily to treat illnesses of deep sea divers. There is recently a renewed interest in this field all over the world. Acute traumatic wounds, crush injuries, burns, gas gangrene and compartment syndrome are indications where addition of hyperbaric oxygen may be life and limb saving. Patients who are suffering with non-healing ulcers, decubitus ulcers (bed sores) and all late sequelae of radiation therapy are also benefited with HBO therapy. Acute hearing loss and many neurological illnesses are also now known to possibly benefit from hyperbaric oxygen therapy. This article aims to give a brief overview of the rationale, existing trends and applications of this therapy.

Use and efficacy of hyperbaric oxygen therapy (HOT) in liver disease has not been established. A prospective control study of HOT in liver diseases was undertaken. Sixty cases were selected for this study (30 with HOT and 30 with conventional therapy only). Almost equal number of Hepatitis B virus surface antigen (HbsAg) positive cases were included in both groups. All patients were male. Only cases with serum bilirubin over 10 mg/dl were included in this study. It was found that study cases recovered faster, gained appetite and had an earlier sense of well-being. There was faster disappearance of pruritus, earlier achievement of normal liver function, HbsAg negativity and overall shorter duration of hospital stay and convalescence. Short term adverse effects were unremarkable.
