Filter by:Therapeutic hypothermia (TH) is the standard of care for newborns with moderate to severe hypoxic-ischaemic encephalopathy (HIE) born at 35 weeks or more of gestation. Many neonatal units do not use enteral feeding during TH, in fear of increased risk of complications. Withholding enteral feedings during TH lacks supporting evidence. The aim of the study is to determine if enteral feeding during TH in patients with HIE is safe and assess its effects. Investigators will perform multicenter randomized controlled study in level III neonatal intensive care units on infants qualified for TH. Infants will be randomized into 2 groups: (1) unfed during 72 hours of TH; (2) fed group, which will start receive enteral feeding with mother milk or human donor breast milk at 10 ml/kg/day during first day of TH, 20 ml/kg/day during second day, 30 ml/kg/day during third day. The primary outcome will be (1) combined necrotizing enterocolitis or death, (2) length of hospital stay. The secondary outcomes will be (1) time to full enteral feeding, (2) late-onset sepsis, (3) Test of Infant Motor Performance scoring, (4) MRI scoring, (5) MR spectroscopy parameters.
In this study, we aim to compare the effect of active external rewarming to passive rewarming in healthy research participants on core temperature. The participants will be cooled to a core temperature of 35 degress C, the rewarmed using 2 different scenarios. Scenario 1 will be with passive rewarming, scenario 2 with active rewarming. Shivering will be pharmacologically inhibited using Buspirone and Meperidine.
Cardiopulmonary bypass (CPB) surgery present risk of acute postoperative neurological complications. These complications are most often postoperative cognitive dysfunction (confusion, cognitive disorders, executive disorders) with a prevalence of up to 40% at 5 years, and ischemic (stroke) with an incidence of between 0.4 and 14%. The causes are usually multifactorial, but altered cerebral perfusion during CPB surgery is an important prognostic factor. Data regarding the effect of deep hypothermia on cerebral perfusion during CPB in adult are scarce. Currently, aortic arch replacement following aortic dissection or aneurysm, and pulmonary artery endarterectomy (PAE) in the treatment of pulmonary hypertension of post embolic origin are performed under deep hypothermia. In this latter indication, the need to obtain a completely bloodless operating field necessitates complete circulatory arrest during short period of time to enable the surgeon to optimally remove the clot materials located into the pulmonary arteries. To protect the brain and avoid irreversible brain injury during circulatory arrest(s), body temperature is lowered at 18-20°C. Deep hypothermia can lead to significant arterial vasoconstriction, which can reduce the blood supply to the brai. It also increases the solubility of CO2 in the blood, leading to respiratory alkalosis, which can also lead to vasoconstriction of cerebral vessels, increasing the risk of ischemic lesions. In adult there is no consistent data on the cerebral perfusion during PAE surgery under deep hypothermia at 18-20°C. Animal studies showed that cerebral regulation seems to be preserved under these conditions. A better understanding of the effect of deep hypothermia on cerebral perfusion during PAE surgery is essential to adapt our management to limit the occurrence of postoperative neurological complications.
The purpose of this study is to determine the safety and feasibility of weaning from the incubator at a lower post-natal weight at 1600 grams. Our hypothesis is that early weaning from the incubator to a crib/bassinet is safe and may result in a decrease in length of hospital stay while maintaining appropriate growth velocity. Specific outcomes the investigators will evaluate are the length of hospital stay and growth velocity at early weaning.
Transient mild hypothermia (core body temperature 35-32°C) is common and usually without consequences for the brain or other organs. However, prolonged severe accidental hypothermia (core body temperature below 28°C) due to accidents is rare, and usually fatal in more than 50% of cases. Little is known on its physiopathology, on prognostic factors for rewarming decision or ideal rewarming techniques for better survival. Furthermore, complications after successful rewarming are extremely frequent and very often severe or fatal. Accidental hypothermia is a frequent problem during the winter months and can be caused by snow sport accidents, near drowning and urban cold exposure. The International Hypothermia Registry's principle goal is to increase knowledge on accidental hypothermia by creating the largest database on accidental hypothermia which will comprise enough patient data to give a statistical power since the causes of accidental hypothermia and its treatment varies greatly. The International Hypothermia Registry (IHR) will enable improvement of pre- and in-hospital treatment and rewarming methods, study survival predictors and prevention of post-rewarming complications. By this way, the IHR will permit the establishment of evidence-based diagnosis and treatment guidelines.
Unintentional perioperative hypothermia is a common occurrence. One of the recommendations of the guidelines to prevent hypothermia is the use of active warmers. It is known that low-flow anesthesia protects from hypothermia compared to high-flow anesthesia. In this study, we aimed to compare the efficacy of using active air blown heater and resistive heater in preventing hypothermia in patients with low flow and high flow inhalation anesthesia
There are conflicting results in the literature explaining the relationship between surgical site infection (SSI) and inadvertent perioperative hypothermia (IPH). Although it is thought that the risk of IPH is lower in laparoscopic surgery types due to the short duration of the surgical procedure, these conflicting results raise doubts as to whether there is a relationship between IPH and SSI in laparoscopic surgery patients. A randomized controlled study will be planned in the future to examine the effect of IPH on SSI in patients who will undergo laparoscopic cholecystectomies. The study will be conducted in the general surgery clinic and operating room of a university hospital. It will be completed with a total of 100 patients, 50 of whom will be in the case group, and 50 will be in the control group.
The aim of this clinical trial is to study the impact of ultra-early transnasal evaporative cooling after cardiac arrest and subsequent hypothermia at hospital, on survival with complete neurologic recovery, compared to currently recommended normothermia. The study population will consist of patients 18-79 years old, with out-of-hospital cardiac arrest with initial shockable rhythm. The main research question it aims to answer is whether there is a difference in survival with complete neurologic recovery at 90 days after cardiac arrest between the group of patients that received ultra-early cooling, compared to the group that was treated with normothermia. Participants will be randomized to two groups. One group (the intervention group) will receive ultra-early trans-nasal evaporative cooling initiated by EMS personnel at the scene of the cardiac arrest, and subsequent systemic hypothermia for 24 hours at hospital arrival. The other group (the control group), will receive standard of care (advanced cardiac life support and normal body temperature (normothermia)).
The prevalence of hypothermia across low-resource settings is high, especially in countries with high neonatal mortality rates. If left untreated, hypothermia can additionally result in a significant comorbidity, and has been linked to a reduction in the effectiveness of treatment for other newborn conditions. Effective thermal care for hypothermic newborns is not widely available in low-resource settings due to cost of consumables and spare parts. In this study, the research team wish to evaluate the efficacy of a novel neonatal warming mattress in treating hypothermic newborns. Warming mattress, 'Celsi Warmer', has been developed by Rice 360 Institute for Global Health Technologies, in conjunction with African clinicians, to be a robust, low-cost, and easy-to-use warming mattress which can address the challenges of hypothermia. This is a single-arm, non-randomized, prospective intervention study. Up to 90 eligible infants at the neonatal wards of the Lagos University Teaching Hospital will be recruited to evaluate the efficacy of Celsi Warmer in rewarming hypothermic newborns. Infants temperature will be monitored during thermal intervention and the performance of the device will be evaluated. The temperatures of each infant will be compared before, during, and after the intervention.
The purpose of the study is to evaluate the efficacy of a novel low-cost warming device to provide thermal care for newborn babies with hypothermia in low-resource hospitals. During the study, research participants will receive thermal care via the Celsi Warmer. Aside from thermal treatment, research participants will receive the standard of care from the neonatal unit, and will also be closely monitored by study personnel throughout the study. The results from this study will allow us to determine if the Celsi Warmer is an effective tool for warming and monitoring newborns in wards of low-resource hospitals. The research team hopes to demonstrate that the Celsi Warmer is effective for the appropriate treatment of newborn hypothermia in hospitals in low-resource settings.
