Filter by:A significant medical risk associated with hypothermia during exercise in a cold environment cardiac arrhythmia due to a possible autonomic conflict. However, little is known about the changes in heart rate and cardiac function after prolonged cold water swimming. The investigators propose to measure the changes in core temperarure during and after a cold water swim at at a water temperature below 15.5°C qualifying for English Channel swim and to test the association with changes in heart rate variability, resting electrocardiogram and left ventricle function.
Globally, over 15 million neonates are born preterm each year. They account for approximately 30% of global neonatal deaths and 19% of total neonatal deaths in Bangladesh. They usually die because they cannot maintain normal temperature due to their weight, immature skin and underdeveloped thermal regulatory capacity of the brain. Maintaining continuous KMC for at least 16-20 hours/day, is sometimes not feasible for mothers or caregivers. In addition, we also have the challenge of keeping preterm or LBW neonates warm during transportation. The scientists at icddr,b, Johns Hopkins University, and George Mason University developed the re-usable thermal jacket for keeping preterm or low-birth-weight neonate warm. We propose to build on previous work by systematically testing the safety of the 'thermal jacket' among preterm or low birthweight (LBW) neonates. Objective of this study is to conduct clinical safety trial of the thermal jacket to test whether the thermal jacket can retain euthermia of preterm or LBW neonates for 2 hours.
This study was conducted to determine the effects of actively warming the patient and using warmed intravenous (IV) fluid during cesarean section on maternal and infant well-being
Intraoperative hypothermia is a common and potentially severe complication during major surgical procedures. The consequences of intraoperative hypothermia can be far-reaching, affecting patient outcomes, recovery times, and overall healthcare costs. Therefore, strategies aimed at preventing hypothermia are of paramount importance in modern surgical practice. However, despite all the measures taken, some patients may still become hypothermic at the end of surgery. Understanding these factors can enhance the quality of daily practice. Medications used intraoperatively can decrease the threshold for vasoconstriction, and some of them have been reported to influence thermoregulation. For example, ephedrine is a sympathomimetic amine used to maintain hemodynamic stability, but there is a report about its thermogenic effect. One study found that patients who received an intraoperative infusion of ephedrine had a significantly lower decrease in core temperature and these patients had a more stable hemodynamic profile. It was employed in obese patients for its thermogenic and appetite-suppressing effects until its adverse effects prevented its use. Ephedrine has an unintended yet significant effect on body temperature regulation, which has raised questions about its role in contributing to the incidence of hypothermia in the postoperative period. The purpose of this study is to investigate the potential relationship between the intraoperative use of ephedrine and the incidence of hypothermia following major surgery.
The goal of this clinical trial is to compare different strategies for normothermia prevention in patients undergoing body contouring and other Aesthetic Plastic Surgery procedures. The main question(s) it aims to answer are: - Do active measures have an impact on preventing hypothermia in patients undergoing cosmetic procedures? - Does an active normothermia prevention protocol have any impact in the clinical setting? Four different protocols will be used for patient peroperative preparation for normothermia.
Hypothermia (core temperature ≤35°C) is a frequent and life-threatening complication after mountain accidents, near-drowning, and intoxications, and can provoke arrhythmia, reduced cardiac contractility, and cardiac arrest. The hypothermic heart may be insensitive to defibrillation with a core temperature <30°C. Also, below <30°C after successful defibrillation, a perfusing rhythm often degenerates to ventricular fibrillation (VF) again. Repeated defibrillation can induce myocardial injury. Thus, the guidelines of the European Resuscitation Council (ERC) suggest delaying further defibrillation attempts until the core temperature is >30°C if VF persists after 3 shocks. Epinephrine should be withheld if core temperature is <30°C. Advanced Life Support (ALS) guidelines of the American Heart Association (AHA) state that it may be reasonable to perform further defibrillation attempts according to the standard algorithm and to consider administration of a vasopressor during cardiac arrest (Table 1). This discrepancy between ERC and AHA guidelines can be explained by the different interpretations of mainly animal data, which show that vasopressors increase the chances of successful defibrillation <30°C, defined as return of spontaneous circulation (ROSC) for at least 30 seconds. The guidelines of the Wilderness and Environmental Medicine Society (WMS) state that a single shock at a maximum power can be given for patients with a temperature <30°C. The aim of this study is to evaluate clinical course of hypothermic patients(<30°C) undergoing defibrillation. The primary aim is to evaluate the success ratio of defibrillation, defined as ROSC for at least 30 seconds. Secondary aims are the recurrence rate of ventricular fibrillation, the number of defibrillation attempts per patient, the presence of cardiac dysfunction after defibrillation and the cerebral performance category (CPC) score at the end of hospitalization.
The current trend in most cardiac surgeries was to use rocuronium as it provides faster recovery in train-of-four ratio compared to other aminosteroid non-depolarising neuromuscular blocker. However, as most cardiac centres' standard of care does not perform any neuromuscular monitoring nor antagonism of neuromuscular blockade effect, residual neuromuscular blockade could potentially be the key to delayed extubation. As such, Cis-atracurium's organ-independent Hofmann elimination could be in favour.
The goal of this observational study is to compare frequency of intraoperative hypothermia between fragilitly groups of eldery patients who underwent orthopedic surgical procedures. It aims to answer those questions: - İs there any difference between fragility groups in terms of hypothermia frequency during orthopedic surgical procedures? - Are there any other factors that influence the frequency of hypothermia such as age, body mass index, room temperature etc. ? Participants body temperature before anestesia application,and before surgery had started was measured and measurament was done during whole procedure. Measuraments had been done by tympanic thermometer.
The optimal method of prehospital insulation and rewarming of hypothermic patients have been subject of debate, and there is a substantial lack og high-quality evidence to guide providers. One question concerns whether or not the patients clothing should be removed prior to being wrapped in an insulating model with a vapor barrier. Evaporative heat loss is one of four mechanisms of heat loss, and preventing evaporative heat loss should be a prioritized task for providers. Removal of wet clothing usually means subjecting the patient to the environment, but will reduce the evaporative heat loss considerably. An other alternative is to encapsulate the patient in a vapor barrier. Evaporative heat loss will stop when the humidity inside the vapor barrier reaches 100%. We aim to investigate whether it is recommended to removed wet clothing or encase the patient in a vapor barrier.
