Results

[34] (U.S., 1972)

Exertional heatstroke

(n = 8)

Pulmonary artery catheter; fluid therapy

Hemodynamic profile; response to fluid therapy; mortality

Hyperdynamic profile, n = 7; hypodynamic profile, n = 1; optimal response to fluid: 1,200 ml per 4 hours and cooling; mortality: 0%

[31] (U.S., 1979)

Classic heatstroke

(n = 7)

Pulmonary artery catheter; fluid therapy

Hemodynamic profile; response to fluid therapy; mortality

Hyperdynamic profile, n = 2; hypodynamic profile, n = 5; failure to respond to fluid: 6,000 ml per 24 hours and cooling; no pulmonary edema; mortality: 71%

[37] (Saudi Arabia, 1989)

Classic heatstroke

(n = 13)

Pulmonary artery catheter; fluid therapy

Hemodynamic profile; response to fluid therapy; mortality

Hyperdynamic profile, n = 13; fluid 400 to 1,200 ml per 4 hours, n = 8, no pulmonary edema; fluid 1,200 to 1,800 ml per 4 hours, n = 5, pulmonary edema; mortality: 7.6%

[38] (Saudi Arabia, 1993)

Classic heatstroke

(n = 10)

Pulmonary artery catheter

Hemodynamic profile; mortality

Hyperdynamic profile, n = 8; hypodynamic profile with normal systemic vascular resistance, n = 1; normodynamic profile, n = 1; mortality: 10%

[39] (Saudi Arabia, 1991)

Classic heatstroke

(n = 34)

CVP monitoring; fluid therapy

CVP; response to fluid therapy; mortality

CVP < 3 cm H₂O, n = 12 (35.3%); CVP 3 to 10 cm H₂O, n = 16 (47%); CVP >10 cm H₂O, n = 6 (17.6%); fluid 500 to 2,500 ml titrated to CVP (3 to 8 cm H₂O); optimal response, no pulmonary edema; mortality: 0%

CVP, central venous pressure.
