Critique of the Dornier HM3 lithotripter as a clinical algesimeter.

The power and nociceptive intensity of shock waves generated by the Dornier HM3 extracorporeal shock wave lithotripter (ESWL) are voltage dependent and suited to algesimetry in a controllable voltage range of 8-30 kV. Fidelity of the HM3 as an algesimeter was tested by: (1) In vitro measurements of shock pressure at voltages between 14 and 30 kV were recorded by a force transducer at the point of clinical focus. (2) Unanaesthetized volunteer (n = 5) assessment and VAS pain scores of shocks in the range of 10-24 kV, yielding highly significant correlations between blinded randomized shock voltage (r = 0.

Is dantrolene effective in heat stroke patients?

Dantrolene (2.45 mg/kg body weight, range 2 to 4) was administered iv in eight heat stroke (HS) patients and compared with a control group of 12 patients of similar age, weight, and temperature range (41.9 degrees to 44 degrees C).
