Active clinical trials for "Hypothermia"

Studying the effect of passive versus Blanket roll III modality of therapeutic hypothermia (TH)on myocardial function of asphyxiated neonates through using tissue Doppler (TD).

Core body temperature is normally tightly regulated to within a few tenths of a degree. The major thermoregulatory defences in humans are sweating, arteriovenous shunt vasoconstriction, and shivering. Inadvertent hypothermia often complicates prolonged surgery. In patients becoming sufficiently hypothermic, reemergence of thermoregulatory vasoconstriction usually prevents further core hypothermia. The extent to which anesthetics reduce the vasoconstriction threshold depends on the type of drug and its concentration.

Introduction: Intravenous infusion of amino acids during cesarean delivery in mothers and neonates improves neonatal growth. Amino acid before and during anesthesia also prevents hypothermia and associated untoward effects. Method: After ethical approval, this prospective randomized double blind controlled study is being conducted in the university hospital of BPKIHS. Seventy six parturients (ASA 1 & 2) undergoing cesarean delivery without fetal distress, intrauterine growth retardation, congenital malformation or premature labor will be enrolled. For a period starting from approximately one hour prior to spinal anesthesia, Group 1 and Group 2 patients will receive 200 ml of amino acid and lactated ringers solution respectively at 2 ml/kg/hr. The ambient operating room temperature will be maintained near 23º C. No heating methods will be applied apart from covering with a blanket. Primary outcome measure will be neonatal rectal temperature at 0, 5 and 10 min after birth. Secondary outcome measures will be APGAR scores and suckling reflex in the newborn, change in rectal temperature relative to baseline and discomfort related to cold sensation in the mother and the occurrence of shivering both in the mother and newborn.

This study examined whether 20 minutes of prewarming prior to gynecological laparoscopic surgery prevented inadvertent post-operative hypothermia. Treatment group received prewarming using a forced air body warming, control group received no active warming system. Both groups were then warmed with forced air warmer intraoperatively.

We hypothesized that sequential compression device (SCD) compression system might induce more decreases on core temperature by increasing lower extremity blood flow. And, this study investigated the effects of SCD compression system on body temperature in patients during total intravenous anesthesia (TIVA) with propofol and remifentanil.

The overall hypothesis is that placing infants 1000-2500 grams in plastic bags when compared to routine care will reduce the risk of hypothermia (< 36.5 degrees C) without increasing hyperthermia (> 37.5 degrees C).

Hypothermia leads to increased morbidity and mortality. Heat loss mainly occurs during anesthesia and surgery. Therefore prevention of hypothermia in pediatric patients undergoing general anesthesia is very important. However, there is very little information about effectiveness of various insulating materials used in the operating room. Objective: To compare the effectiveness of cotton and plastic for prevent intraoperative hypothermia in pediatric patients.

During anaesthesia for caesarean section it is common to lose heat and become hypothermic, (<36 degrees C). In order to try and avoid this all women are given warmed intravenous fluid and insulated from cold surfaces. There are also 2 types of machine available to actively warm women; Forced Air Warming - that uses a disposable sheet the woman lies upon with lots of air pockets that have warm air blown into them continuously by a fan. Conduction Warming Mattress - a thin mattress which covers the operating table and the woman lies on top. The padded mattress has strips of material that heat up when electricity passes through it, similar to a normal electric blanket. We plan to carry out a randomised controlled trial to compare these 2 methods with the current practice of no active warming. The hypothesis for this study is that active warming women during elective caesarean section prevents women's temperature from dropping and keeps them more comfortable than if active warming were not used.

3500 people suffer from out of hospital cardiac arrest each year in Denmark. Therapeutic hypothermia to 33 degrees celsius is now standard treatment of comatose cardiac arrest patients. The investigators are challenged in our attempt to predict outcome of these patients by both low body temperature in itself and the sedative and relaxing drugs used to keep the patient in a coma. This study is a substudy in a large international multicenter randomized trial that investigates the possible benefit of 48 hours of therapeutic hypothermia versus todays standard of 24 hours. In this substudy the investigators will approach early prediction of neurological outcome using a combination of new examinations backed up by well established ones to engage this challenge from different angles and find a battery of combined examinations, that together will enable us to accurately predict outcome at an earlier stage. Our examinations have been chosen from the three fields of neurophysiology, biochemistry and neurology and consist of electroencephalography (EEG), somatosensory evoked potentials (SEP), biomarkers and clinical examinations such as brain stem reflexes chosen for their prognostic reliability.

Aim of the study is to determine whether endovascular systemic cooling to a target temperature of 34-35°C initiated before, and maintained during Carotid EndoArterectomy (CEA), is feasible and safe
