We report the first case of suspected carbon monoxide poisoning treated by hyperbaric oxygen therapy by using a portable hyperbaric stretcher. A 40-year-old British man in Kabul, Afghanistan, was found unresponsive in his apartment. Initial treatment consisted of oxygen by mask at a Combat Support Hospital for several hours, with minimal improvement. Operational security and risk prevented his ...

Trimix (a mixture of helium, nitrogen, and oxygen) has been used in deep diving to reduce the risk of high-pressure nervous syndrome during compression and the time required for decompression at the end of the dive. There is no specific recompression treatment for decompression sickness (DCS) resulting from trimix diving. Our purpose was to validate a rat model of DCS on decompression from a tr...

INTRODUCTION Controversy surrounds the use of salvage therapies to treat sudden sensorineural hearing loss (SSNHL), with no consensus on recommendations. While several studies have demonstrated the effectiveness of intratympanic administration of steroids (ITS) and hyperbaric oxygen (HBO) treatment, few have compared the efficacy of ITS and HBO therapy in patients with refractory SSNHL. OBJEC...

INTRODUCTION Most cases of decompression sickness (DCS) occur soon after surfacing, with 98% within 24 hours. Recompression using hyperbaric chamber should be administrated as soon as feasible in order to decrease bubble size and avoid further tissue injury. Unfortunately, there may be a significant time delay from surfacing to recompression. The time beyond which hyperbaric treatment is non ef...

OBJECTIVE We conducted a prospective pilot study to assess the safety and efficacy of hyperbaric oxygen (HBO) for the treatment of interstitial cystitis (IC). METHODS Six patients underwent 30 sessions of 100% oxygen inhalation in a hyperbaric chamber and were followed up over 15 months. The measures of efficacy were changes in pain and urgency (visual analog scales), alteration in the patien...

BACKGROUND AND PURPOSE Intrapleural fibrinolytic therapy is a technique used to treat empyemas and parapneumonic effusions. Cerebral air embolism is an unusual potentially severe complication of this technique. Summary of Case- A patient with parapneumonic pleural effusion underwent pleural lavage with streptokinase when he suddenly demonstrated focal neurological signs and seizures. The CT rev...

The brain depends on a continuous supply of oxygen to maintain its structural and functional integrity. This study measured T1 from MRI under normobaric air, normobaric oxygen, hyperbaric air, and hyperbaric oxygen (HBO) conditions as a marker of tissue pO2 since dissolved molecular oxygen acts as an endogenous contrast agent. Brain tissue T1 decreased corresponding to increased pO2 with increa...

We used near-infrared spectroscopy (NIRS) to evaluate cerebral blood oxygenation changes in subjects undergoing cesarean section under spinal anesthesia (SP) with hyperbaric bupivacaine (group H, 27 subjects) or isobaric bupivacaine (group I, 15 subjects). In group H, total-Hb, oxy-Hb, and mean blood pressure (MBP) within 20 min after SP were significantly lower than the baseline values. In con...

Cerebral Palsy is a term that encompasses many etiological factors in children diagnosed in utero to age fourteen. Problems may present in utero, peri-natal, and post-natal. Infections, traumatic brain injury, near-drowning, and strokes in children suffering from neurological problems come under the heading of Cerebral Palsy. Hyperbaric oxygenation not only relieves hypoxia but also jumpstarts ...

Aims: To quantify retinal vascular change during and after hyperbaric oxygenation (HO) for 665 weekly 90 minute treatments. Methods: Fundus photographs were taken before, during, and after HO at 2.5 atmospheres absolute pressure (ATA) on days 1, 2, 3, 10, 20, 29, and 30 of treatment on three patients using a specially developed hand held ophthalmoscope with a digital colour camera. Blood vessel...
