Frostbite is an injury caused by the freezing of tissue, causing varied levels of tissue damage and necrosis. Case reports have shown a positive effect of hyperbaric oxygen (HBO₂) in such injuries, in acute cases as well as delayed (up to 21 days) presentation with complications. In this case report we present the course of hyperbaric treatment of two patients (a brother and sister, age 58 and 62) who sustained frostbite injuries to both feet 28 days earlier while hiking in the Himalayas. They were initially treated in Nepal following local protocol; afterward their primary care in the Netherlands was managed by the Burn Centre at Maasstad Hospital in Rotterdam...

Complete blood count (CBC) is a routine diagnostic procedure for patients and a part of routine health inspection for healthy individuals. The effect of hyperbaric oxygen (HBO₂) on CBC is not known. The objective of this study was to determine the effects of HBO₂ on blood parameters in CBC with long-term HBO₂ therapy. In this study, patients received HBO₂ at the department of Underwater and Hyperbaric Clinical Medicine. CBC results were obtained at specific time points during HBO₂ therapy. The study recruited a total of 140 patients who met the research inclusion criteria...

INTRODUCTION: Hyperbaric oxygen (HBO₂) treatment results in elevated production of reactive oxygen species (ROS) that leads to cellular damage. Thymoquinone (TQ) is reported to have anti-inflammatory and antimicrobial activity and may suppress the generation of free radicals. The goal of this study is reduction of side effects of hyperbaric oxygen therapy with thymoquinone treatment. METHODS: 30 female Sprague-Dawley rats were randomly assigned to one of three groups (n = 10 per group)...

BACKGROUND: Headache is the most common symptom in carbon monoxide (CO) poisoning. While the mechanism of CO-induced headache is not well defined, it is felt that cerebral vasodilation plays a role. Clinical experience has demonstrated oxygen breathing is effective in resolving CO headache. However, the effectiveness of normobaric oxygen has never been compared to hyperbaric oxygen in this regard. METHODS: A 2016 paper by Ocak, et al. reported the response of CO headache pain severity to four hours of normobaric oxygen breathing in 82 patients using a 0-10 analog scale...

Hyperbaric oxygen (HBO₂) therapy is currently used for the treatment of chronic wounds, radiation-induced soft tissue necrosis, several oxygen-deficiency conditions and decompression sickness. In addition to the current indications, much empirical and experimental data suggest that HBO₂ therapy may benefit autoimmune diseases by suppressing immunity, but the underlying mechanism is not well understood. Therefore, in the present study, we investigated whether HBO₂ prevents the development of collagen-induced arthritis (CIA) in association with alteration of the immune balance between pro-inflammatory Th17 and anti-inflammatory regulatory T cells (Tregs)...

We offer the first report of hyperbaric oxygen (HBO₂) therapy to treat early surgical wound breakdown after oronasal fistula and cleft palate repair in the pediatric population. We present four patients' experiences after undergoing HBO₂ therapy. HBO₂ was initiated as soon as an oronasal fistula was identified. Three of the children underwent 10 HBO₂ treatments with the fourth undergoing 11 treatments. There were no adverse effects during treatment; none of the patients required decompressive myringotomy...

The diagnosis of decompression illness (DCI), which is based on a history of decompression and clinical findings, can sometimes be confounded with other vascular events of the central nervous system. The authors report three cases of divers who were urgently transported to a hyperbaric facility for hyperbaric oxygen treatment of DCI which at admission turned out to be something else. The first case, a 45-year-old experienced diver with unconsciousness, was clinically diagnosed as having experienced subarachnoid hemorrhage, which was confirmed by CT scan...

INTRODUCTION: Single-hose scuba regulators dived in very cold water may suffer first- or second-stage malfunction, yielding complete occlusion of air flow or massive freeflow that rapidly expends a diver's air supply. PURPOSE: This study, conducted in Antarctica, evaluated the under-ice performance of a sampling of commercially available regulators. METHODS: Seventeen science divers logged a total of 305 dives in -1.86°C seawater under 6-meter-thick Antarctic fast-ice over two field seasons in 2008 and 2009...

A 57-year-old woman was admitted to the intensive care unit in a state of severe hypotensive shock following a session of hyperbaric oxygen (HBO₂) therapy. Shock was attributed to gastric barotrauma, which resulted in a massive venous gas embolism. Gastric barotrauma was attributed to the presence of a filled gastric band/cuff during the HBO₂ therapy that prevented expanding gas from escaping on decompression. After deflation of the gastric band, two additional HBO₂ sessions were performed and resulted in complete symptom resolution...

INTRODUCTION: Indocyanine green fluorescent angiography (ICFA), commonly used to assess vascularity in patients with non-healing lower extremity wounds, is emerging as a useful adjunct for hyperbaric oxygen (HBO₂)therapy patients. We describe the use of ICFA to measure vascularity and help tailor an appropriate HBO₂ regimen in a patient with breast soft tissue radiation necrosis (STRN). CASE REPORT: 67-year-old female with a history of right breast cancer treated two years previously with lumpectomy and radiation therapy (6200 cGy), developed open wounds in the right breast...

Traumatic brain injury (TBI) may cause persistent cognitive dysfunction. A pilot clinical study was performed to determine if hyperbaric oxygen (HBO₂) treatment improves cognitive performance. It was hypothesized that stem cells, mobilized by HBO₂ treatment, are recruited to repair damaged neuronal tissue. This hypothesis was tested by measuring the relative abundance of stem cells in peripheral blood and cognitive performance during this clinical trial. The subject population consisted of 28 subjects with persistent cognitive impairment caused by mild to moderate TBI suffered during military deployment to Iraq or Afghanistan...

This paper presents the replacement of a traditional wired communication link of the hyperbaric chambers with a wireless ZigBee-based system. This move allows a reduction in the costs of seals capable of withstanding the internal pressures and gives rise to a more versatile system. The new system is able to capture and process individual vital signs like the electrocardiography signal, and other analog sources, sending the data to an external computer and allowing analysis, representation and sharing with medical staff...

The venous bubble load in the body after diving may be used to infer risk of decompression sickness (DCS). Retrospective analysis of post-dive bubbling and DCS was made on seven studies. Each of these investigated interventions, using an 18 meters of sea water (msw) air dive profile from Royal Navy Table 11 (Mod Air Table), equivalent to the Norwegian Air tables. A recent neurological DCS case suggested this table was not safe as thought. Two-hundred and twenty (220) man-dives were completed on this profile...
