Effect of Hypothermia on BIS and PSI Correlation During Cardiopulmonary Bypass

The goal of this observational study is to evaluate whether hypothermia affects the relationship between electroencephalography-derived indices during cardiac surgery in adult patients undergoing cardiopulmonary bypass. The main questions it aims to answer are: Does the correlation between Bispectral Index (BIS) and Patient State Index (PSI) change between normothermic and hypothermic phases during cardiopulmonary bypass? How do BIS and PSI values change in response to decreasing body temperature? Participants will: Undergo standard general anesthesia for elective on-pump coronary artery bypass surgery Be monitored simultaneously with BIS and PSI devices during surgery Have data recorded at predefined temperature-based time points during cardiopulmonary bypass

Constructing a Risk Prediction Model for Intraoperative Hypothermia in Children Under General Anesthesia

Intraoperative hypothermia refers to a core body temperature below 36.0°C during surgery, which is common in surgical patients. Due to the fact that children's body temperature regulation function is not yet fully developed, they are light in weight, and their blood vessels are superficial, children are very susceptible to the influence of environmental temperature. With the effects of anesthetic drugs, exposure of the surgical field, and disinfection of the surgical area, children face a higher risk of intraoperative hypothermia than adult patients. Studies have shown that the incidence of intraoperative hypothermia can be as high as 80%. Intraoperative hypothermia can lead to increased adverse cardiovascular events, poor coagulation, slower healing of surgical incisions, or wound infection, threatening the health of children, resulting in prolonged postoperative hospitalization and increased hospitalization costs. Therefore, there is an urgent need to develop a tool for predicting intraoperative hypothermia suitable for children, identify high-risk groups early, and take preventive measures as soon as possible, thereby reducing a series of complications caused by hypothermia. The purpose of this study is to clarify the current status and risk factors affecting intraoperative hypothermia in children, to provide a theoretical basis for clinical medical staff to provide intraoperative thermal insulation care for children, and on this basis to construct an intraoperative hypothermia risk prediction model to identify the probability of hypothermia in children at an early stage, so as to take targeted thermal insulation measures.

Impact of a Global Warming Strategy of the Patient on the Prevalence of Hypothermia in the Recovering Room

50% of patients are hypothermic when they arrive in the recovery room. This hypothermia is potentially at risk for the patient (increases bleeding, risk of infection, risk of cardiac involvement, morbid mortality) and 33,2% steel hypothermic when they discharge from the recovering room. The anesthesia team must prevent these risks through prevention and treatment measures. Currently the majority of patient warming is done only in the operating room, we want to measure the impact of the extension of this warming before and after the surgery on the patient's temperature and on side effects related to hypothermia.

Evaluation of The Relationship Between Perioperative Hypothermia and Emergence Agitation

The main aim of our study was to investigate the relationship between perioperative hypothermia and postoperative emergence agitation.

Perioperative Warming Measures in Cesarean Delivery

The purpose of this study is to evaluate the best method for keeping patients warm during cesarean deliveries and the effect of temperature change on the patient and baby
