Evaluation of fatal diving accidents in Turkey
In this study, autopsy files of fatal dive accident cases were reviewed to evaluate demographic data, type of diving, purpose of dive, seasonal distribution, autopsy findings, and causes of death. We reviewed 56 fatal dive accident files from autopsy units in cities where dive activities are concentrated and from the archive of the Turkish Underwater Federation. Four cases were excluded from the study since we were unable to obtain autopsy reports. Of 52 cases there were 20 scuba divers, two surface-supplied divers and 30 breath-hold divers. The majority of cases involved males (94%). The average age of 50 cases was 38.6; ...

Middle ear barotrauma during hyperbaric oxygen therapy; a review of occurrences in 5,962 patients.
Abstract Hyperbaric-associated middle ear barotrauma (MEB) is one of the most common side effects of the exposure to hyperbaric oxygen (HBO2) therapy. This retrospective observational study of 5,962 patients undergoing longterm therapy for chronic conditions took place at the local Diving and Hyperbaric Medicine Unit (DHMU) in Villafranca-Verona (Italy), a DHMU that administers, in multiplace chambers, more than 20,000 HBO2 treatments per year. The study was designed to weight and analyze both the incidence and severity of MEBs at the facility. Thanks to a systematic recording method over eight years, 2003-2010, w...

Methods for preventing middle ear barotrauma in computer-controlled pressurization of monoplace hyperbaric chambers.
Abstract Middle ear barotrauma (MEB), one of the side effects of hyperbaric oxygen (HBO2) therapy, sometimes cannot be directly diagnosed during the therapy itself. Instead, its incidence and degree are judged based on subjective statements made by patients when in conversation with medical staff regarding how they feel. To prevent MEB in practice, it is proposed that the tympanic membrane evaluation system and automatic control chamber developed in a previous study be applied as part of a prevention algorithm [16]. The proposed algorithm, which determines and equalizes the unbalanced pressure of a subject based o...

Rescue of a submerged convulsing diver.
Abstract In 2018, the Medical Panel of the NATO Underwater Diving Working Group (UDWG) discussed the question of the rescue and management of a submerged unresponsive compressed-gas diver. The Panel reviewed the 2012 recommendation by the UHMS Diving Committee with respect to the specific recommendation in a convulsing diver using a half-face mask and separate mouthpiece, to delay surfacing until the clonic phase had subsided if the mouthpiece was in place. There is a paucity of scientific, epidemiological, experimental and observational human studies to substantiate this guidance. Experimental animal studies sugg...

Decrease of tetrahydrobiopterin and NO generation in endothelial cells exposed to simulated diving.
Conclusion: NO generation in intact human endothelial cells was decreased by simulated diving, as well as by hyperoxic exposure, while BH4 levels seem to be affected only by hyperoxia. Hence, the results suggest that BH4 is not the sole determinant of NO generation in HUVEC. PMID: 31051061 [PubMed - in process] (Source: Undersea and Hyperbaric Medicine)

Pulmonary barotrauma: assessment and investigation in divers.
Abstract Decompression illness (DCI) is an uncommon problem but can be significant in terms of morbidity and, very rarely, mortality. The mechanisms of DCI are pulmonary barotrauma and decompression sickness due to inert gas supersaturation. After the initial management phase, identification of predisposing factors is important to help advise divers regarding future risk and avoidance. Here we present four cases of DCI where pulmonary barotrauma was the likely causative mechanism. We highlight the important features in assessment for pulmonary barotrauma and advising divers on the risk of a recurrence. PMID: ...

Hyperbaric oxygen therapy for dermal ischemia after dermal filler injection with calcium hydroxylapatite: a case report.
Abstract Dermal injection of fillers is a popular and relatively safe aesthetic procedure. Severe complications are rare, but they do occur. One of the most threatening complications after dermal filler injection is skin necrosis due to vascular occlusion. Different treatment options are available, including the use of hyperbaric oxygen (HBO2) therapy. A 46-year-old female received facial dermal filler injections with calcium hydroxylapatite at an aesthetic clinic. A few days after injection she developed a burning pain, numbness of the skin and white discoloration in the injected area. Two days after injection tr...

Abdominal decompression illness following repetitive diving: a case report and review of the literature.
Abstract The complete pathophysiology of decompression illness is not yet fully understood. What is known is that the longer a diver breathes pressurized air at depth, the more likely nitrogen bubbles are to form once the diver returns to surface [1]. These bubbles have varying mechanical, embolic and biochemical effects on the body. The symptoms produced can be as mild as joint pain or as significant as severe neurologic dysfunction, cardiopulmonary collapse or death. Once clinically diagnosed, decompression illness must be treated rapidly with recompression therapy in a hyperbaric chamber. This case report invol...

Abdominal decompression illness following repetitive diving: a case report and review of the literature.
We report the case of a 46-year-old male fisherman diver who presented with chronic inguinal pain that radiated to the lower left limb. Living and working in a fishing port in Yucatan, he had a prior history of DCS. A diagnosis of avascular necrosis in the left femoral head secondary to DCS was made via analysis of clinical and radiological findings. The necrosis was surgically resolved by a total hip arthroplasty. Dysbaric osteonecrosis is a more probable diagnosis. In this region fishermen undergo significant decompression stress in their daily fishing efforts. Further studies regarding prevalence of dysbaric osteonecros...

The panic triangle: onset of panic in scuba divers.
Abstract Panic arising from physical or psychological stress is a common issue in reported incidents and accidents in scuba diving. Due to its effect on perception, thinking and diver behavior, the panic reaction is often a significant factor in the generation or escalation of problems, potentially leading to injuries and fatalities. The instinctive behaviors associated with panic are incompatible with the constraints of scuba diving (e.g., flight response to threat, leading to rapid ascent). Although the dangers are well known, the psychological mechanisms of panic and the implications for prevention/risk reducti...

Oxygen exposures at NASA's Neutral Buoyancy Lab: a 20-year experience.
Abstract Astronauts training for extravehicular activity (EVA) operations can spend many hours submerged underwater in a pressurized suit, called an extravehicular mobility unit (EMU), exposed to pressures exceeding 2 atmospheres absolute (ATA). To minimize the risk of decompression sickness (DCS) a 46% nitrox mixture is used. This limits the nitrogen partial pressure, decreasing the risk of DCS. The trade-off with using a 46% nitrox mixture is the increased potential for oxygen toxicity, which can lead to severe neurologic symptoms including seizures. Suited runs, which typically expose astronauts of 0.9-1.1 ATA ...
