Background & Problems:
Post-operation hypothermia tends to induce complications. Sixty percent of robotic-assisted mitral valve surgery patients experienced hypothermia while admitted to our intensive care unit (ICU), resulting in prolonged ICU stays and 57% (eight) of those patients with hypothermia also experiencing cardiac arrhythmia. The causes of hypothermia in our ICU included low temperature in the operating room, delayed initiation of blanket coverage after surgery, and lack of postoperative thermal blankets, insufficient cardiopulmonary bypass rewarming time, cold ICU beds, lack of in-service training for hypothermia, and lack of procedure auditing.
Purpose:
This intervention was designed to reduce the incidence of hypothermia in ICU patients undergoing robotic-assisted mitral valve surgery upon ICU admission from 60% to 36% and the one-hour hypothermia rate from 43.3% to 26%.
Resolutions:
We implemented several measures including increasing the room temperature, pre-heating the ICU bed, achieving team consensus regarding prolonging the rewarming time after cardiopulmonary bypass, establishing a blanket warming area for postoperative patient use, and holding in-service training to enhance the awareness of the nurses were implemented.
Results:
The incidence of hypothermia in ICU patients receiving robotic-assisted mitral valve surgery upon ICU admission decreased from 60% to 19.4%, while the one-hour hypothermia rate decreased from 43.3% to 19.4%.
Conclusions:
Using systemic interprofessional collaboration, combined thermal care can be achieved to significantly reduce the incidence of postoperative hypothermia in patients undergoing robotic-assisted mitral valve surgeries resulting in higher patient care quality and shorter ICU stays. We recommend applying this combined method to improve the quality of perioperative care for long-duration and major surgical procedures that involve large postoperative wounds and for patients who may require wider exposure during their operation.
