Active clinical trials for "Hypothermia"

We 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.

This 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.

The 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.

Rivaroxaban, 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.

The 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.

Total 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.

Comparison 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.

The 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.

Hypothermia 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.

Data indicate that neurological prognostication is difficult after cardiac arrest if mild therapeutic hypothermia is part of the post resuscitation care. Cerebral oxygenation detected by near-infrared spectroscopy, could be a new, non-invasive index marker for outcome assessment after cardiac arrest. The investigators hypothesize that cardiac arrest survivors with a continuously low cerebral oxygenation index have a poor prognosis.
