Central nervous system oxygen toxicity during routine hyperbaric oxygen therapy.
Hyperbaric oxygen therapy is associated with a recognized risk for clinically apparent central nervous system (CNS) toxicity. The risk for oxygen-induced convulsions during routine hyperbaric treatment of most routine conditions is extremely low. However, reports from the 1980's describing the incidence of CNS oxygen toxicity differ significantly from more recent reports since 1996. This retros...
متن کاملCentral Nervous System Oxygen Toxicity and Hyperbaric Oxygen Seizures.
INTRODUCTION The use of hyperbaric oxygen (O2) as a therapeutic agent carries with it the risk of central nervous system (CNS) O2 toxicity. METHODS To further the understanding of this risk and the nature of its molecular mechanism, a review was conducted on the literature from various fields. RESULTS Numerous physiological changes are produced by increased partial pressures of oxygen (Po2)...
متن کاملAttenuation of brain hyperbaric oxygen toxicity by fasting is not related to ketosis.
The effect of 24 h of fasting and changes in blood glucose and beta-hydroxybutyrate (BHB) level on latency to seizures in hyperbaric oxygen (HBO2) was studied. Conscious, unrestrained rats implanted with cortical electroencephalogram electrodes were exposed to 0.5 MPa (gauge pressure) O2 until seizures were observed. Fasting for 24 h significantly (P < 0.01) decreased blood glucose (from 8.6 +/...
متن کاملBaroreflex-mediated cardiovascular responses to hyperbaric oxygen.
The cardiovascular system responds to hyperbaric hyperoxia (HBO2) with vasoconstriction, hypertension, bradycardia, and reduced cardiac output (CO). We tested the hypothesis that these responses are linked by a common mechanism-activation of the arterial baroreflex. Baroreflex function in HBO2 was assessed in anesthetized and conscious rats after deafferentation of aortic or carotid barorecepto...
متن کاملHow can hyperbaric oxygen contribute to treatment?
Hyperbaric oxygen (HBO2) is used in a sports medicine setting to reduce hypoxia and edema and appears to be particularly effective for treating crush injuries and acute traumatic peripheral ischemias. When used clinically, HBO2 should be considered as an adjunctive therapy as soon as possible after injury diagnosis. Treatment pressures for acute traumatic peripheral ischemia range from 2.0 to 2...
