Active clinical trials for "Hypothermia"

The study is a comparison of a patient warming system using a forced-air, non-compressible under-body mattress (Möck & Möck, Hamburg, Germany) versus a regular forced-air underbody mattress system during pediatric cardiac catheterization in 40 patients. The hypothesis is, that the non-compressible mattress provides better warming with less incidence of perioperative hypothermia (Core temperature < 36 °C) and faster warming slope (°C / time). The study is prospective, randomized, controlled and single-blinded. Inclusion criteria will be pediatric patients < 1 year of age without fever or a treatment of therapeutic hypothermia.

This study aims to report mortality and neurological outcome 180 days after drowning incident in patients with accidental hypothermia vs normothermia following drowning-related OHCA in Denmark during a six-year period from 2016-2021.

The purpose of this study is to determine whether mild hypothermia causes reduction of vasoconstriction in microcirculation after clipping of aneurysms, and affects the blood flow in small diameter arteries at operating site (ischemia-hyperemia) and occurrence of vasospasms during the period of 14 postoperative days measured by transcranial Doppler.

The primary aim of the current study will be to determine if the use of an underbody heating mattress during cesarean sections will decrease the incidence of postoperative hypothermia, defined as core temperature less than 36C, and if hypothermia occurs, time to normothermia. As part of the primary outcome the difference in the incidence of shivering, its severity, and need for treatment will be investigated. As a secondary goal other maternal perioperative outcomes will be studied i.e. estimated blood loss, change in hemoglobin level on the morning after surgery ie postop day 1, need for blood transfusion, rate of wound infections, length of hospital stay, maternal satisfaction, time to first breastfeeding, time to first 'skin to skin' contact. The relationship between maternal hypothermia and newborn outcomes of temperature and APGAR scores will also be evaluated. Active preoperative and intraoperative warming may prevents inadvertent perioperative hypothermia and may be beneficial for pregnant patients undergoing cesarean delivery. The underbody warming mattress may be a step towards finding a suitable form of warming that is comfortable for awake patients, does not interfere with skin to skin contact and maternal-fetal bonding.

Delayed cord clamping has been shown to decrease the risk of bleeding in the brain of premature infants. However this procedure is not standard due to concerns that the premature infant will get too cold. In this study the investigators look at using a plastic covering and a chemical warmer to keep the small premature baby warm while waiting 30-60 seconds to clamp the umbilical cord.

Hypothermia contributes to a significant portion of neonatal deaths. Kangaroo mother care (KMC) is a safe and effective method of warming; however, it is not always feasible, and not possible in settings such as resuscitation or clinical instability. Electric warmers are the standard of care in developed countries, but are extremely costly, complicated with risk of causing both hypo and hyperthermia with misuse, and often not feasible in settings without stable electricity. Through a multi-institutional collaboration, the investigators have developed an electricity-free infant warmer. After laboratory based prototype testing for safety and efficacy, the investigators aim to study the supervised use of the warmer under routine implementation conditions in a resource-limited setting.

Glyceryl trinitrate is used in coronary artery bypass grafting surgery. This surgery frequently employs hypothermic cardiopulmonary bypass, where the whole body is cooled down to 28-32 °C to arrest the heart, and protect the organs from ischemic insult. When the cardiac repair or grafting is done, the body is warmed to 37 °C. During this "rewarming period", the heart has to beat against the vessels, all of which are constricted due to hypothermia. To overcome this constriction of the vessels, and decrease the workload of the heart, glyceryl trinitrate is infused. This drug causes significant dilatation in arteries and veins, which allows the heart to pump the blood with less force. The dilatation of the vessels also allows the body to rewarm more easily. The investigators' concern is whether increased infusion rates of glyceryl trinitrate may cause uncontrolled rewarming of the brain or not. The investigators will measure the temperature of the brain using a temperature probe located in the nasal cavity. The temperature will be recorded at each minute during the the rewarming period. Results of two commonly used infusion rates of glyceryl trinitrate will be compared.

Social network targeting strategies can be used to improve the delivery and uptake of health interventions. We will enroll approximately 30,000 individuals into a randomized controlled trial of different targeting algorithms in order to explore how social network dynamics affect the uptake, diffusion, and group-level normative reinforcement of key neonatal and infant health behaviors and attitudes in 176 rural villages in the Copan region of Honduras. Our goal is to develop methods by which global health practitioners can exploit face-to-face social network interactions in order to maximize uptake of neonatal and infant health interventions. The villages will be randomly assigned to 16 cells of 11 villages each in a 2 x 8 factorial design of different targeting algorithms.

Ten infants undergoing therapeutic hypothermia for hypoxic-ischemic encephalopathy will be enrolled in a new protocol that will allow mothers to hold their infants during the hypothermia treatment period. This is a safety study that will assess whether or not there is an increase in adverse event frequency in infants that are held during hypothermia. Parents and NICU nurses will be given a questionnaire after holding is complete investigating their feelings on maternal-infant bonding and safety of the holding protocol.

This study characterizes the changes in corticospinal excitability that accompany basic cold stress via skin cooling that result in reduced skin or core temperature and shivering.
