Diving medicine: contemporary topics and their controversies.

SCUBA diving is a popular recreational sport. Although serious injuries occur infrequently, when they do knowledge of diving medicine and/or where to obtain appropriate consultation is essential. The emergency physician is likely to be the first physician contact the injured diver has. We discuss 8 subjects in diving medicine which are contemporary, yet may have controversies associated with them. From this information the physician dealing primarily with the injured diver will have a basis for understanding and managing, as well as where to find additional help, for his/her patients' diving injuries.

Cigarette smoking and transcutaneous oxygen tensions: a case report.

We report the effects of acute smoking cessation on transcutaneous oxygen (PtcO2) measurements in room air and with hyperbaric oxygen (HBO2) of an extremity at risk for amputation. The reports on cigarette smoking and PtcO2 do not discuss acute smoking cessation. PtcO2 measured 46 h after smoking cessation increased 10% while breathing room air and 34% with HBO2, as compared to measurements made before smoking cessation.

Effect of increased atmospheric pressure on radial keratotomy.

PURPOSE: To evaluate the effect of increased atmospheric pressure on visual acuity in patients who have had radial keratotomy (RK). SETTING: Long Beach Memorial Medical Center, Long Beach, California, USA. METHODS: This controlled clinical study comprised 4 eyes that had RK and 4 control eyes that were age and sex matched. All patients had prehyperbaric chamber examinations consisting of manifest and cycloplegic refractions, intraocular pressure (IOP), keratometry, and corneal pachymetry. They were then placed into the hyperbaric chamber for 1 hour. Immediately after the patients were removed from the chamber, the examinations were performed again. RESULTS: No statistically significant changes in visual acuity, refractive error, IOP, keratometry, or pachymetry occurred in the 2 groups. CONCLUSION: The results of this study indicate that, unlike at high altitudes, RK is stable at increased atmospheric pressure. This suggests that RK patients can engage in recreational scuba diving without encountering deleterious visual changes.

Preventive foot care. A user-friendly system for patients and physicians.

Our user-friendly foot skin and toenail grading system is simple to understand for both patients and physicians. Current medical practice dictates that primary care physicians deliver the most comprehensive care possible for their patients. This includes preventive care and documentation of outcomes. Our approach simplifies evaluation and management of the majority of foot skin and toenail conditions in compromised hosts. Reimbursement for the extra care is justified, and authorized billing codes exist. Our system helps to prevent the physical, emotional, and financial costs associated with severe foot wounds and nail disorders. We remind our patients that proper foot care is as important in preventing foot complications as drug therapy is in preventing complications in other organs. Our approach to foot skin and toenail care is largely prophylactic and can be easily instituted in a primary care practice.

Hyperbaric oxygen therapy for acute smoke inhalation injuries.

Hyperbaric oxygen therapy is an important adjunct in the management of respiratory injuries secondary to smoke inhalation, especially when injury is complicated by inhalation of a toxic chemical such as carbon monoxide or cyanide. For carbon monoxide poisoning, such therapy has become a standard of practice. As more information becomes available concerning the ability of hyperbaric oxygen to reduce reperfusion injuries, we anticipate that this therapy will become a standard of practice for managing smoke inhalation injuries and cyanide poisoning as well.

Delayed use of hyperbaric oxygen for treatment of a model anterior compartment syndrome.

This study examines the effect of delayed exposure to hyperbaric oxygen on muscle necrosis and edema development following compartment syndromes in the canine hindlimb. Compartment syndromes (100 mm Hg for 8 h) were generated in one anterolateral compartment of six anesthetized dogs. After a 2-h delay, three 1-h hyperbaric oxygen treatments (2 atm absolute pure oxygen) were given during the next 12 h. Two days later, technetium-99m stannous pyrophosphate (99mTc Sn-PYP) was injected intravenously; 3 h later, samples were obtained from the pressurized and contralateral control muscles, weighed for edema development, counted for 99mTC Sn-PYP uptake, and evaluated histologically. Hyperbaric oxygen treatments, even when delayed 2 h, reduced muscle necrosis and intramuscular edema to negligible levels (p less than 0.05) compared with untreated animals. In addition, muscle morphology remained essentially normal in all hyperbaric oxygen-treated animals. We conclude that even if hyperbaric oxygen treatments are delayed 2 h, edema and muscle necrosis are reduced significantly in a model compartment syndrome.

Hyperbaric oxygen reduces edema and necrosis of skeletal muscle in compartment syndromes associated with hemorrhagic hypotension.

This study examined the effect of exposures to hyperbaric oxygen on the development of the edema and necrosis of muscle that are associated with compartment syndromes that are complicated by hemorrhagic hypotension. A compartment syndrome (twenty millimeters of mercury for six hours) was induced by infusion of autologous plasma in the anterolateral compartment of the left hind limb of seven anesthetized dogs while the mean arterial blood pressure was maintained at sixty-five millimeters of mercury after 30 per cent loss of blood volume. These dogs were treated with hyperbaric oxygen (two atmospheres of pure oxygen) and were compared with six dogs that had an identical compartment syndrome and hypotensive condition but were not exposed to hyperbaric oxygen. Forty-eight hours later, edema was quantified by measuring the weights of the muscles (the pressurized muscle compared with the contralateral muscle), and necrosis of muscle was evaluated by measuring the uptake of technetium-99m stannous pyrophosphate. The ratio for edema was significantly (p = 0.01) greater in dogs that had not been exposed to hyperbaric oxygen (1.15 +/- 0.01) than in the dogs that had been treated with hyperbaric oxygen (1.01 +/- 0.03), and the ratio for necrosis of muscle was also significantly (p = 0.04) greater in dogs that had not had hyperbaric oxygen (1.96 +/- 0.41) than in those that had been treated with hyperbaric oxygen (1.05 +/- 0.11). Comparisons were also made with the muscles of four normal control dogs and separately with the muscles of six normotensive dogs that had an identical compartment syndrome and normal blood pressure and were not treated with hyperbaric oxygen.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of smoke inhalation by hyperbaric oxygen.

Five patients with smoke inhalation from house fires presented to the hospital in a comatose state. Carboxyhemoglobin levels were elevated in all five patients, mean=32% +/- 6. Arterial blood gases revealed the following means: pH 7.16 +/- 0.06; PCO2 35 mm HG +/- 10.5; HCO3 12.6 mEq/L +/- 0.07; base excess -16 mEq/L +/- 1.58; PO2 353 mm Hg +/- 149; O2 saturation 66% +/- 5.5. The patients were presumed to have both cyanide and carbon monoxide intoxication and were treated with the cyanide antidote kit and hyperbaric oxygen (HBO). Four of five patients awoke within 15 minutes of reaching maximum pressure and remained neurologically intact thereafter. The fifth patient died one week later. Cyanide blood levels drawn prior to treatment revealed a mean of 1.62 microgram/mL +/- 1.44. The highest cyanide level was 3.9 microgram/mL (the death) and the lowest 0.35 microgram/mL. We conclude that smoke inhalation can result in acute cyanide poisoning and that hyperbaric oxygen is a useful adjunct in the treatment of smoke inhalation.

Osteomyelitis in the spinal cord injured: a review and a preliminary report on the use of hyperbaric oxygen therapy.

Spinal Cord Injury patients are liable to develop osteomyelitis mostly by extension from pressure ulcers. In 2055 records reviewed in the Long Beach Spinal Cord Injury Service of the Veterans Administration Medical Center, the incidence was found to be 4.3 per cent. Of these osteomyelitis developed secondary to pressure ulcers in 88 per cent, the rest developed as a result of trauma and/or surgery. Forty-four patients manifesting chronic osteomyelitis were treated in a monoplace hyperbaric oxygen (HBO) chamber, in addition to receiving antibiotic and surgical treatment. HBO was found useful as an adjunct to help to resolve the bone infection and encourage wound healing. Two-thirds of the patients were cured, and the follow-up was from 6 months to 9 years. We believe that HBO is a useful adjunctive therapeutic measure in the management of chronic osteomyelitis in the spinal cord injured and in the prevention of its complications.

Gas gangrene.

Gas gangrene is not a disease of the past. Despite improved awareness, earlier care of trauma victims, new antibiotics, and advanced monitoring techniques, histotoxic clostridia continue to cause loss of life and limb. A 20-year literature review on gas gangrene (Part I) indicates that a combined therapy approach with early recognition, surgical intervention, appropriate antibiotics, and hyperbaric oxygen (HBO) provides optimal care. Part II, a 15-year clinical experience, appears to be the largest English-language series reported using the combined therapy of antibiotics, surgery, and hyperbaric oxygen. One hundred thirty-nine patients (95 males and 44 females), average age, 38 years, were admitted with clostridial myonecrosis. Sixty-seven were in shock at admission and the 27 deaths occurred in this group. One hundred twelve patients (81%) survived the infection. There was a 5% mortality in post-traumatic extremity clostridial myonecrosis. Age and concurrent disease increased the mortality rate, as did delay from time of diagnosis to aggressive combined treatment.
