Effect of Prewarming on Inadvertent Hypothermia and Thermal Comfort

Inadvertent perioperative hypothermia (IPH), where core body temperature is less than 36 °C or 96.8°F, occurs in 26-90% of patients undergoing elective surgery. This preventable anesthesia- and surgery-related complication affects patients’ outcome and is associated with increased risk for surgical site infections (SSIs), bleeding, blood transfusions, and decreased patient thermal c omfort.

BACKGROUND In our outpatient post anaesthesia unit patients reported that they were feeling cold with or without shivering. Anaesthetic agents cause reduced thermoregulation, initially by redistribution of blood flow from core to periphery, later by negative balance between thermogenesis and heat loss. Even mild peri-operative hypothermia increases the risk of surgical wound infections, bleeding, impaired cardiac function, shivering, and decreases comfort. OBJECTIVE(S) We aimed to evaluate which of our current active warming measures, self-warming blanket or forced-air-warming blanket, were most effective in preventin...

We present the case of a 75-year-old man with repeated lower limb hematoma caused by consumptive coagulopathy from a type B chronic aortic dissection. His abdominal aorta was replaced with a Y-shaped graft 30  years prior to admission. As his previous aortic stent graft treatment failed, he underwent open surgical prosthetic graft replacement of the descending aorta under deep hypothermia. To reduce intra- and postoperative bleeding, we avoided cutting the ribs and intercostal arteries. The aneurysm was approached only through the 8th intercostal space; however, as the proximal descending aorta was inaccessible from t...

ConclusionsRAKT is feasible and safe only if performed by surgeons with appropriate background in robotic surgery and kidney transplantation after proper surgical training at experienced centres in the mid-term follow-up. Further studies need to confirm the long-term safety of RAKT.

tay T Abstract Massive pulmonary embolism is a well-known cause of sudden cardiac arrest in the adult population. Systemic fibrinolysis can be a life-saving option. Therapeutic hypothermia is highly recommended for nontraumatic sudden cardiac arrest victims to minimize neurological complications. However, there are limited data about the use of therapeutic hypothermia for sudden cardiac arrest victims also treated with systemic fibrinolysis. Concerns about hypothermia-related coagulopathy and a possible tendency to bleeding have limited the use of cooling therapy in such cases. Presently described is a case of sud...

A 72-year-old male cardiac transplant patient presented after sustaining facial and extremity trauma caused by a pit bull dog attack. The case was further complicated by duration of the surgery, bleeding, infection risk, intraoperative hypothermia, immunosuppression, and the risk of sepsis. His anesthetic management required careful coordination with his transplant team. We also sought the expertise of the in-house pharmacist to obtain the appropriate administration strategies for the patient ’s immunosuppressants.

Backgroud: Aortic arch surgery is frequently associated with excessive postoperative bleeding and transfusion of allogeneic blood products. However, the physiopathology of hypothermia induced coagulopathy has never been systematically studied. The aim of the present study is to investigate the impact of the degree of hypothermic circulatory arrest on the changes of the perioperative hemostatic system in pig cardiopulmonary bypass model.

r J Abstract Persistent, uncontrolled bleeding after trauma is one of the leading causes of fatalities in patients with severe injuries. 40% of trauma deaths are associated with massive haemorrhage. Hypoperfusion due to major loss of blood volume leads to tissue damage. In combination with acidosis and hypothermia, a generalized immune response with activation of coagulation is triggered. This leads to trauma-induced coagulopathy. A suitable, early treatment might lead to a significant reduction in morbidity and mortality. PMID: 31212332 [PubMed - in process]

Abstract Targeted temperature management and extracorporeal life support, particularly extracorporeal membrane oxygenation in patients undergoing cardiopulmonary resuscitation, represent outcome-enhancing strategies for patients following in- and out-of-hospital cardiac arrest. Although targeted temperature management with hypothermia between 32°C and 34°C and extracorporeal cardiopulmonary resuscitation bear separate potentials to improve outcome after out-of-hospital cardiac arrest, each is associated with bleeding risk and risk of infection. Whether the combination imposes excessive risk on patients is,...
