Filter by:Neonatal Encephalopathy is a serious condition arising from unexpected lack of cerebral blood flow and oxygen supply to the foetal brain at the time of birth. Every year, approximately one million babies die from neonatal encephalopathy in low and middle-income countries and a quarter of these deaths occur in India. In the past decade, a number of clinical trials in high-income countries has shown that cooling therapy along with optimal neonatal intensive care reduces death and neurodisability after neonatal encephalopathy. Cooling therapy is now used as a standard therapy after neonatal encephalopathy in all high income countries, including the UK. Although the burden of neonatal encephalopathy is far higher in low and middle-income countries, the safety and efficacy data on cooling therapy from high income cooling trials cannot be extrapolated to these settings, due to the difference in population co-morbidities and sub-optimal neonatal intensive care. The HELIX trial proposes to examine whether whole body cooling to 33.5°C initiated within 6 hours of birth and continued for 72 hours reduces death or neurodisability at 18 months after neonatal encephalopathy in public sector neonatal units in India. A total of 408 babies with moderate or severe neonatal encephalopathy will be recruited from the participating centres in India over an 18 to 24 month period. The babies will be randomly allocated to whole body cooling or usual care. The cooling therapy will be achieved using an approved cooling device (Tecotherm) that is already in clinical use in the UK and in India. MR imaging and spectroscopy will be performed at 1 week of age to examine the brain injury. Neurodevelopmental outcomes will be assessed at 18 months of age. Primary outcome measure is death or moderate/severe neurodisability at 18 months.
Hypothermia is a common problem in traumatized patients leading to severe complications such as impaired coagulation, increased rate of wound infections and overall patient discomfort among others. Therefore, the investigators test out the new self warming ReadyHeat® blanket device against the currently used cotton wool blanket in terms of effects on the prevention and treatment of hypothermia.
The purpose of this study is to compare two novel active rewarming techniques in mildly hypothermic people. Volunteers will undergo 3 cooling trials in a circulating bath at 14 degrees celsius and will then be rewarmed with either shivering alone, warmed iv fluids (IVF), or water perfusion pads applied to the hands and feet. The investigators hypothesize that both heated IVF and water perfusion pads to the arteriovenous anastomoses (AVAs) will prove to provide significantly superior rewarming rates than shivering alone.
To compart differences on the effect on core temperature between anesthetic induction with intravenous propofol versus inhalation induction with sevoflurane
The aim of this study is to assess the impact of different environmental factors on the ability for a thermistor-based epitympanic thermometer to accurately read the temperature of a normothermic individual and thereby estimate their feasibility and reliability in the austere pre-hospital setting.
Background: Postoperative hypothermia may result in relevant complications such as adverse cardiovascular events, wound infection, and coagulopathy with consecutive blood loss. Patients with open cardiac surgery using cardiopulmonary bypass are particular at risk for hypothermia. The study of Karalapillai and coworkers, analyzing a huge database incl. 43,158 patients with CPB, revealed 66% of them experiencing postoperative hypothermia during the first 24 hours and 0.3% longer than that. During cardiac surgery great parts of body surface including wound surface are exposed. Many of these patients receive large amounts of infusions and transfusions, and undergo hemodilution during CPB, which may additionally contribute to development of hypothermia. Objective of the planned study is to find out incidence and duration of postoperative hypothermia and also risk factors for hypothermia in cardiac patients. Further objective is the incidence of postoperative complications and its relation to postoperative core temperature. Methods: A retrospective chart review 780 patients who had been underwent cardiac surgery with CPB Included are patients ≥ 18 years old. Excluded are patients with preoperative hyperthermia (> 37.8 °C) and hypothermia (> 36 °C). The following parameters will be recorded: temperature is measured at ICU after arrived and after 6 hours which is primary outcome, biometric data include age, sex, body weight, height, ASA physical status, surgical procedure includes emergency cases, anesthetic and surgical (bypass-) times, infusion/transfusion-regimen, blood loss and urine output, coolest temperature during bypass, method of temperature protection, and the outcome of operation . All data will be described in number and percent and Pearson chi-square method will be used for analyze correlation between hypothermia and risk factor . P-value <0.05 will be defined to significant.
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 aim of the study is to evaluate a patient prewarming concept following the recommendations of the S3-guideline "Prevention of perioperative hypothermia" with respect to incidence and complications of perioperative hypothermia. The study hypothesis is that postoperative core temperature in adult patients after prewarming is significantly higher than in patients who were treated following actual standard protocol (passive insulation).
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; 1. 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. 2. 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.
