Perioperative Hypothermia and Myocardial Injury After Non-cardiac Surgery
Perioperative CareSurgery--Complications2 moreWe propose to test the hypothesis that aggressive warming reduces the incidence of major cardiovascular complications, compared to routine care. Half of the participants will be randomly assigned to routine care (core temperature ≈35.5°C), while the other half will receive aggressive warming (>37°C core temperature) in a multi-center trial.
Mild Hypothermia Influence on Patient Outcome in Major Abdominal Surgery
Surgical Site InfectionBleedingThis study investigate associations between mild hypothermia (patients' core temperature ≤ 36.0 degrees Celsius) and intra-operative blood loss and surgical site infections (SSI) in patients undergoing major abdominal surgery.
Can the SpotOn™ Zero-Heat-Flux-Thermometry Sensor Accurately Measure Core Temperature in Children?...
Hypothermia; AnesthesiaHypothermia Following Anesthesia1 moreThe present study aims to assess the accuracy of the SpotOn™ Zero-heat-flux-thermometry sensor in measuring core temperature in the paediatric population in the perioperative period.
The Effects of Hypothermia and Acidosis on Coagulation During Treatment With Rivaroxaban Measured...
TraumaHypothermia2 moreRivaroxaban, a non-vitamin K oral anticoagulants, is increasingly used to prevent stroke in patients with atrium fibrillation. It has previously been demonstrated that a point-of-care coagulation instrument (ROTEM) can detect the effects of rivaroxaban. Further, the ROTEM instrument can also detect the effects of hypothermia and acidosis. Given that trauma induced coagulopathy is enhanced by both hypothermia, acidosis and rivaroxaban, the investigators want to investigate any synergistic effects between hypothermia or acidosis and rivaroxaban. In an attempt to do so the investigators designed the current experimental study with the purpose to investigate the effects of rivaroxaban together with hypothermia or acidosis using the ROTEM assay EXTEM. The hypothesis is that a synergistic prolongation of hypothermia or acidosis and rivaroxaban can be detected in the initiation of clot formation demonstrated in the primary outcome variable, clotting time of the ROTEM assay EXTEM. Secondary outcome variables include direct effect on clotting time and direct and synergistic effects on clot formation time and alfa angle of hypothermia and acidosis detected in the ROTEM assay EXTEM.
Observational Examination of Thermoregulation in Total Joint Arthroplasty
HypothermiaTotal joint patients have poor outcomes with infection since they are having permanent hardware implanted. Infection prevention in this group is therefore critical and a major source of discussion in both the orthopedic and anesthesia literature. Hypothermia has been shown to increase the risk of infection and blood loss. However, studies have not examined when in the operation or how fast patients temperatures drop. This study will observe how patients' temperatures change during total joint arthroplasty. By identifying when body temperature changes occur, prevention strategies may be developed and implemented.
Hypothermia's Impact on Pharmacology
Cardiac ArrestHypothermiaThe purpose of the study will help us understand the complex interaction between hypothermia (cooling) and pharmacogenetics (how specific genes effect how drugs are handled), and their impact on how routinely given sedation drug are broken down and used by the body when given to children after cardiac arrest (when heart stops pumping blood) and are critically ill.
Temperature Measurement in Surgical and Intensive Care Patients - Comparison of Four Measurement...
HypothermiaHyperthermiaComparison of four methods for measuring temperature perioperatively in patients scheduled for laparoscopic surgery and intensive care patients who are hypo-, normo-and hyper terme; Bladder Monitoring, Nasopharyngeal, SpotOn TM, Zero heat flux method and Temporal Scanner. The study is a single-center, observational study carried out by the Central Surgical and Intensive Section at Vestfold Hospital Trust.
Comparison of the Effect of Remimazolam With Sevoflurane on Postanesthetic Shivering
Anesthesia; HypothermiaThe incidence of postanesthetic shivering (PAS) after general anesthesia is affected by the anesthesia maintenance agents. This study compared the effect of remimazolam with sevoflurane on PAS in patients with laparoscopic gynecologic surgery under general anesthesia.
Perioperative Hypothermia in Patients Submitted to Transurethral Resection
Hypothermia; AnesthesiaPeroperative ComplicationHypothermia is a frequent perioperative complication. Its appearance can have deleterious effects such as myocardial ischemia or perioperative bleeding. When the negative effects of anesthesia on temperature are aggravated by other factors, such as glycine infusion in transurethral resection, temperature can decrease even more. Once the temperature has decreased, its treatment is difficult. Preoperative warming prevents hypothermia, lowering the temperature gradient between core and peripheral compartments and reducing thermal redistribution. The most recent clinical practice guidelines advocate for active prewarming before induction of general anaesthesia since it is very effective in preventing perioperative hypothermia. However, the ideal warming time prior to the induction of anesthesia has long been investigated. This study aims to evaluate if different time periods of preoperative forced-air warming reduces the incidence of hypothermia at the end of surgery in patients submitted to transurethral resection. This is an observational prospective study comparing routine practice of pre-warming in consecutive surgical patients scheduled to undergo elective transurethral resection between March 2014 and April 2018. Three-hundred patients are included in this study and prewarming will be applied following routine clinical practice. The prewarming time will depend on the time the patient has to wait before entering in the operating theatre. Measurement of temperature will be performed using a tympanic thermometer. Patients will be followed throughout their hospital admission. Data will be recorded using a validated instrument and will be analysed using the statistics program R Core Team.
Heat Loss Prevention in Very Preterm Infants in Delivery Rooms: A Multicenter, Randomized, Controlled...
HypothermiaPreterm InfantHypothermia after delivery is a world-wide problem associated with morbidity and mortality. The conventional approach of drying the baby with a pre-warmed towel and radiant warmers is unsuccessful in a large proportion of very preterm infants. Polyethylene occlusive skin wrapping covering the infant's body up to the neck will reduce postnatal heat loss in very preterm babies and represents the standard of care recommended by the International Guidelines for Neonatal Resuscitation. The use of a polyethylene head cap will also reduce heat loss 9 and its efficacy is comparable to that obtained with the wrap. However, the proportions of hypothermic infants at NICU admission (temperature <34°C) in the wrapped group (62%) as well as in the infants covered with a polyethylene cap (43%) remain high. The combination of body and head protection with a polyethylene wrap needs to be evaluated further. The investigators conducted a prospective, randomized, controlled trial in very preterm infants to evaluate whether a polyethylene total body wrapping (body plus head) prevents heat loss after delivery better than polyethylene occlusive wrapping.
