Answer

Conventional surface cooling blankets are also suboptimal because of poor surface contact with the patient’s skin. However, a combination of water-circulating cooling device and ice packs are effective at rapidly cooling patients and are fair at maintaining target temperature. Many clinical studies have used this combination. The patient is sandwiched between 2 blankets or the cooling device's heat-exchange pads are placed and then ice packs are applied. When the target temperature is achieved, the ice packs are removed and the blanket or device is used to maintain the target temperature. Relatively newer medical devices, like those shown below, are available that have adhesive gel that facilitates heat exchange and are considerably more effective in the rate and maintenance of cooling.
