Lidocaine as an adjunct to hyperbaric therapy in decompression illness: a case report
decompression hyperbaric therapy Lidocaine
2009/7/8
A recreational scuba diver with nervous system decompression illness had a poor response to hyperbaric therapy. On the basis of available and supportive in vivo data, he was then given a continuous in...
Intravascular bubble composition in guinea pigs: a possible explanation for differences in decompression risk among different gases
decompression decompression sickness breathing gas bubble animal guinea pig rat
2009/7/8
Differences in risk of decompression sickness (DCS) that have been observed among inert gases may reflect differences in gas solubility or diffusivity or both. A higher risk gas might generate a large...
Effect of severity, time to recompression with oxygen, and re-treatment on outcome in forty-nine cases of spinal cord decompression sickness
decompression sickness outcomes recompression spinal cord treatment re-treatment case reports human
2009/6/12
For systematic study of the effects of clinical severity, time to recompression with oxygen, and re-treatment on outcome from spinal cord DCS, case records from the recompression chamber at the U.S. N...
Spinal decompression sickness:hydrophobic protein and lamellar bodies in spinal tissue
decompression animal sheep
2009/6/12
Four basic studies have addressed the question of why the spinal cord is so vulnerable to decompression injury, with symptoms exceeding those related to the brain by a ratio often quoted as 3:1. Hydro...
Oxy-helium treatment of severe spinal decompression sickness after air diving
spinal decompression sickness HBO air heliox
2009/6/12
Spinal cord injury in DCS after air diving is relatively frequent and often has late sequelae. U.S. Navy oxygen tables are sometimes not satisfactory. The advantage of using helium in these cases is b...
Bubble-induced aggregation of platelets: effects of gas species, proteins, and decompression
decompression hyperbaric platelet aggregation fibrinogen
2009/6/12
We show that bubbles containing different gases (N2, He, Ne, Ar, or an O2-CO2-N2 mixture) are equally potent platelet agonists. The synergistic effect of different platelet antagonists does not seem t...
Relationship between venous bubbles and hemodynamic responses after decompression in pigs
decompression animal pig pulmonary model
2009/6/12
We present a new pig model for studying relationships between venous gas bubbles and physiologic effects during and after decompression. Sixteen pigs were anesthetized to allow spontaneous breathing. ...
Arterial gas bubbles after decompression in pigs with patent foramen ovale
pulmonary air pig animal patent foramen ovale bubble Decompression Sickness
2009/6/12
With patent foramen ovale (PFO), thought to be a risk factor for some forms of DCS, venous bubbles may pass through the patent opening to become arterial bubbles. We exposed 14 anesthetized, spontaneo...
Failure to prevent decompression illness in rats by pretreatment with a soluble complement receptor
decompression complement immune rat animal
2009/6/12
Controversy exists over the role of complement activation in the natural history of decompression illness (DCI), and whether an individual's predisposition to DCI might be influenced by susceptibility...
Release of surfactant and a myelin proteolipid apoprotein in spinal tissue by decompression
animal bovine
2009/6/12
Two experiments have been performed on sections of bovine spinal cord, the first demonstrating that surface-active phospholipid (SAPL) and myelin proteolipid protein (PLP) are released by bubbles prod...
Protective effect of oxygen and heliox breathing during development of spinal decompression sickness
decompression sickness helium heliox oxygen spinal cord animal rat air
2009/6/12
A rat model of spinal decompression sickness (DCS) allows study of spinal cord function for at least 3 h after decompression to 1 atm abs (101 kPa) after an exposure to air at 3.8 atm abs (385 kPa) fo...
Cerebral imaging of decompression injury patients with 18-F-2-fluoro-2-deoxyglucose positron emission tomography
decompression brain neurological
2009/6/12
The objective assessment of the extent of cerebral insult and the effects of therapy in decompression injury patients has proven to be difficult by most imaging modalities. In this pilot study we eval...
Exercise effects on central venous nitrogen tensions after simulated non-decompression dives
saturation exercise air dive
2009/6/12
In five subjects we examined the effect of exercise on the pattern of central venous (right atrial) N2 tensions (PVN2) after ascent from simulated non-decompression dives. The dives consisted of expos...
Prediction of decompression illness using bubble models
bubble model decompression model air nitrox
2009/6/12
The method of maximum likelihood was applied to models of bubble formation and evolution against data involving decompression illness (DCI). Equilibrium and non-equilibrium gas kinetic models were tes...
Does the time course of bubble evolution explain decompression sickness risk?
decompression linear exponential model human air nitrox bubble
2009/6/12
A probabilistic model of decompression sickness (DCS) risk based on linear-exponential (LE) kinetics has given the best fit of the human air and nitrox DCS database. To test the hypothesis that its su...
