Several methods have been used to reduce the incidence of afterdrop such as local rewarming of peripheral tissues during rewarming of the patient.
The second approach to prevent afterdrop is to induce pharmacologic vasodilatation during rewarming that will facilitate heat transfer from core to peripheral tissues.
Afterdrop in core temperature was little more in propofol group (-1.
Mean duration of afterdrop was also little high in propofol group as compared to control group but with no significant difference (p-value 0.
22 Afterdrop occurs as a result of redistribution of heat from warm core to cold periphery and due to heat loss from surgical incision sites to the environment.
Pharmacologic vasodilation is a routinely used method to properly rewarm the patient during rewarming phase of cardiopulmonary bypass and hence to prevent afterdrop.
In this study, we found no significant difference in MST at the time of weaning from CPB and at the end of afterdrop in propofol and control group.
Afterdrop after hypothermic cardiopulmonary bypass: the value of tympanic membrane temperature monitoring.
Although gradual rewarming is indicated in accidental-hypothermia patients to prevent a complication called afterdrop
, there are no published accounts of untoward effects from allowing the temperature of a neurosurgical patient to spontaneously return to normal as the CoolGard system is placed on standby or switched off.
