Background. The effects of pretreatment with caripo-ride (HOE 642 Aventis Pharma, Strasbourg-Cedex, France), a Na ؉ –H ؉ exchanger (NHE) blocker, were studied in a cerebral ischemia–reperfusion model of hypo-thermic arrest. Methods. Fifteen Yorkshire-Duroc pigs (37.1 ؎ 4.2 kg) underwent femoral–jugular bypass and 90 minutes of deep hypothermic circulatory arrest at 19°C. Ten animals were untrea...

The hypothesis was tested that facial sweating at the end of cardiopulmonary bypass (CPB) is a thermoregulatory phenomenon. Twenty-two patients undergoing cardiac surgery with fentanyl anesthesia were studied. Nasopharyngeal temperature, nasal skin temperature, rectal temperature, and mean skin temperature were monitored for 90 minutes after the start of rewarming on CPB. Calf-toe and forehead-...

An inexpensive modular perfused chamber (MPC) designed for low- and normal-temperature live-cell imaging is presented. The device consists of four lathed pieces of stainless steel assembled as a cylindrical open chamber that can hold either round or square glass coverslips. The chamber is connected to a thermal-bath operating with recirculation. For image acquisition at 4°C, cooled air is blown...

Hypothermia is an uncommon presentation of COVID-19 infection, typically observed in patients with severe disease prior to the availability vaccines. However, occurrence hypothermia vaccinated has not yet been documented. This case reports a rare 41-year-old female disease, who suffered from several comorbidities, including heart failure preserved ejection fraction, chronic pericardial effusion...
