Cooling and hemodynamic management in heatstroke: practical recommendations

Abstract

Introduction Although rapid cooling and management of circulatory failure are crucial to the prevention of irreversible tissue damage and death in heatstroke, the evidence supporting the optimal cooling method and hemodynamic management has yet to be established.

Classic heat stroke in a desert climate: A systematic review of 2632 cases

“…This is in line with previous reports that showed that 18%-65% of patients with HS experienced shock [1]. Likewise, hemodynamic studies confirm that the shock state is mainly distributive in nature like in sepsis rather than from volume depletion [70]. In addition to the hemodynamic alterations, the findings of our study revealed that myocardial injury is frequent in HS [71].…”

The effects of heat stress and plane of nutrition on metabolism in growing pigs1

“…This peculiar insulin response agrees with a previous malignant hyperthermic pig model (Hall et al, 1980) as well as data for heat-stressed rodents (Torlinska et al, 1987), growing steers (O'Brien et al, 2010), and lactating cows (Wheelock et al, 2010). Increased insulin action appears to be an important survival adaptation to elevated temperatures as diabetic rats (Niu et al, 2003) and humans (Bouchama et al, 2007) are more susceptible to heat stress. Reasons for hyperinsulinemia during HS are not clearly understood but likely include the key role of insulin in activating and upregulating heat shock proteins (Li et al, 2006).…”

“…In 20-65% of the cases, an acute circulatory failure (shock) is associated [1][2][3] as observed in our patient. Treatment consists mainly of therapeutic cooling and cardiovascular Fig.…”

“…Heat stroke syndrome is defined as core temperature exceeding 40°C associated with a change in mental status ranging from inappropriate behaviour or impaired judgment to delirium, epilepsy or coma [1][2][3]. In 20-65% of the cases, an acute circulatory failure (shock) is associated [1][2][3] as observed in our patient.…”
