Anesthetized patients are unable to turn on normal heat generation (e.g. through
shivering or adrenergic drive) and have impaired peripheral vascular responses i.e.
they are rendered essentially poikilothermic by the anesthetic. Under these
conditions, these catheters will provide approximately the following rates of cooling
and heating in a 75 kg person:
Table 10.
Catheter Cooling Heating
Icy 2 ºC / hr 0.5 ºC / hr
Quattro 2.5 ºC / hr 0.8 ºC / hr
Solex 2 ºC / hr 0.5 ºC / hr
The Icy and Quattro catheters are femoral lines.
The Icy has a lower surface area and is therefore theoretically less likely to cause
thrombo-embolic events. It is also significantly shorter in its applicable length.
