Table 3 Summary of data on cooling methods based on conduction in the treatment of classic heatstroke
From: Cooling and hemodynamic management in heatstroke: practical recommendations
Study (country, year) | Population | Study design | Intervention | Outcomes measured | Results | Limitations |
|---|---|---|---|---|---|---|
[16] (U.S., 1982) | Classic heatstroke (n = 28) | Case series | Iced water immersion; brisk massage with ice; target Trect: ≤38.9°C | Cooling time; mortality; morbidity | Cooling time: < 30 minutes, 93%; cooling time: 30 to 45 minutes, 7%; mortality: 14.3%; neurologic morbidity: 14.3% | Patients switched to brisk massage were not identified |
[24] (U.S., 1986) | Classic heatstroke (n = 39) | Case series | Ice packs to axilla and groin; cold wet sheets applied to torso; ice water lavage; cooling blankets; target Trect: ≤38.9°C | Cooling time; mortality | Cooling time: < 60 minutes, 69%; mortality: 15%; cooling time: > 60 minutes, 31%; mortality: 33%; | Retrospective assignment of group; comparability of the groups at baseline questionable |
