Assessment of hemostaseologic alterations induced by hyperbaric oxygen therapy using point-of-care analyzers.
Exposure to hyperbaric conditions influences the coagulation system. Thromboembolic events and disseminated intravascular coagulation were observed. ⋯ ROTEM and Multiplate were able to detect an activation of platelets after HBO2 therapy via thrombin and arachidonic acid pathways. Previously reported fibrinolysis could not be confirmed.

Initial review of the U.S. Navy's pressurized submarine escape training outcomes.
The U. S. Navy reinstituted pressurized submarine escape training (PSET) for submarine sailors in 2009 after a nearly 30-year absence. ⋯ During the first 39 months of training, 7,025 students screened for PSET with 32% completing all phases, including two pressurized ascents. The most common reason for screening disqualification was presence of upper respiratory congestion. During training, middle ear barotrauma was responsible for 53% of attrition, primarily during the test of pressure.

Case ReportsPneumomediastinum following hyperbaric oxygen therapy for carbon monoxide poisoning: case report.
A 5-year-old boy trapped in a house fire was transported to the emergency department, unconscious with suspected carbon monoxide poisoning. The patient underwent a difficult intubation, but did not initially demonstrate any radiographic abnormalities. The patient remained intubated and underwent hyperbaric oxygen therapy using the carbon monoxide treatment protocol. ⋯ The patient was extubated on post-injury Day #2 and was discharged post-injury Day #4 with no residual clinical sequelae. The development of pneumomediastinum associated with hyperbaric oxygen therapy for carbon monoxide poisoning appears to be a rare phenomenon. However, clinicians should be aware of the risk factors that predispose patients to developing pneumomediastinum and have a low threshold for obtaining routine pre- and post-procedure screening chest radiographs in intubated and critically ill patients, particularly in children.

Case ReportsSwimming-induced immersion pulmonary edema while snorkeling can be rapidly life-threatening: case reports.
It is well known that immersion pulmonary edema can be life-threatening for divers using a self-contained underwater breathing apparatus (scuba). Swimming-induced pulmonary edema in otherwise healthy individuals is not an object of dispute but its real severity is not well known and is probably underestimated. We report two cases of life-threatening acute respiratory distress while swimming and snorkeling, one of which is well documented for swimming-induced pulmonary edema. ⋯ In the case of swimming-induced pulmonary edema, the prognosis is far better than for a cardiac disorder, but it is also dependent on the efficiency of the supervision. Swimmers, divers, race organizers and supervising physicians should be given knowledge of this pathology and its potentially acute occurrence. Adequate organizational dispositions are mandatory to prevent swimming-induced pulmonary edema-related deaths.
