Hypothermic Oxygenated Machine Perfusion of Extended Criteria Kidney Allografts From Brain Death...
Reperfusion InjuryHypothermic Oxygenated Machine PerfusionKidney transplantation (KT) has emerged as the mainstay of treatment for end-stage kidney disease. In an effort to address the widening gap between demand and supply of donor organs, there has been an increase in the numbers of "marginal" or functionally impaired renal allografts that had to be accepted for KT over the decades. The use of extended criteria donor (ECD) allografts is associated with a higher incidence of primary graft non-function (PNF) and/or delayed graft function (DGF). Hypothermic oxygenated machine perfusion (HOPE) has been successfully tested in pre-clinical experiments and in a few clinical series of donation after cardiac death (DCD) in liver transplantation. The present trial is an investigator-initiated pilot study on the effects of HOPE on ECD-allografts in donation after brain death (DBD) KT. Fifteen kidney allografts will be submitted to 2 hours of HOPE before implantation and are going to be compared to a case matched group transplanted after conventional cold storage (CCS).
Efficacy of Warming Garment in the Perioperative Period With Integrated Chemical Heat Packs to Maintain...
HypothermiaEfficacy of Stand-alone, Non-tethered, Self-applying Warming Garment in the Preoperative, Intraoperative and Postoperative Recovery Period; Using an Integrated Chemical Heat Pack Construction, With a View to Maintaining Normothermia During the Peri-operative Period
Cognitive Effects of Body Temperature During Hypothermic Circulatory Arrest
Cognition DisordersIn this study the investigator will randomize 273 subjects to deep (<20°C), low (20.1°C-24°C), or moderate (24.1°C-28°C) hypothermia during aortic arch surgery with circulatory arrest. The primary purpose of this study is to determine the effect of deep vs low vs moderate hypothermia on neurocognitive function, brain functional connectivity, and leukocyte SUMOylation patterns after surgical circulatory arrest in participants.
Dexmedetomidine Pharmacokinetics in Neonates During Therapeutic Hypothermia
Hypoxic-ischemic EncephalopathyThe goal of this proposal is to profile the pharmacokinetics of dexmedetomidine in newborns ≥36 weeks post-menstrual age during therapeutic hypothermia for hypoxic-ischemic encephalopathy.
Influence of Mild Hypothermia on Reversal of Rocuronium With Sugammadex
Underdosing of Other General AnestheticsThe primary efficacy endpoint is the time from the start of administration of sugammadex to recovery of the TOF ratio to 0.9 in deep neuromuscular block (1-2 twitches post-tetanic count) induced by rocuronium during mild hypothermia with core temperatures between 34.5°C and 35°C, and compared with the normal thermal condition. Secondary endpoints include time from the start of administration of sugammadex to recovery of the TOF ratio to 0.7 or 0.8 in both groups, vital signs [heart rate and blood pressure] at pre-reversal, post-reversal, recovery and post-anesthetic visit, the incidence of residual neuromuscular blockade, post-operative nausea and vomiting (PONV) and adverse events during mild hypothermia and the normal thermal condition. We hypothesize that mild hypothermia with core temperatures between 34.5°C and 35°C diminish the efficacy of sugammadex.
Efficacy of a Convective Prewarming System in Prevention of Perioperative Hypothermia
Perioperative HypothermiaAlthough several measures for prevention of perioperative hypothermia have been introduced the last decades, perioperative hypothermia is still a frequent complication and associated with a negative outcome. For not long lasting surgery without specific risk for hypothermia the standard procedure for prevention of perioperative hypothermia is insulation. However, the insulation is often not effective enough to prevent intra- and postoperative hypothermia. The implementation of a prewarming is difficult because of variable OR schedules and therefore not often applied. In the planed prospective, multicenter, randomised-controlled trial will the efficacy of a convective prewarming system on prevention of intra- and perioperative hypothermia (Thermoflect™, TSCI, Amersfoort, NL) be compared to an intraoperative application of forced air warming with or without passive insulation before induction of anesthesia. The studied prewarming device is easy to use and will be applied on the nursery ward 30-60 minutes before transfer of the patient to the OR. Perioperative hypothermia is a common complication in general aesthesia. Perioperative hypothermia is associated with medical risks as intraoperative impaired coagulation due to reversible platelet dysfunction, a prolonged bleeding time and increased intraoperative blood loss. In the postoperative course the perioperative hypothermia is especially for patients with cardiopulmonary diseases a relevant problem. Not at least sensual cold and shivering is uncomfortable for the patient. The study is conducted as a multicenter, prospective, randomised controlled trial. All patients will receive intraoperatively a forced air warming device (Termoflect™/Mistral Air ™). For one intervention group will additionally the insulation with the Thermoflect™ will be applied on nursery ward, the second intervention group will receive additionally a convective air warmer/ reflective blanket (Thermoflect™/Mistral Air™, TSCI, Amersfoort, NL) preoperatively on study day on nursery ward. The aim of the study is to prove the hypothesis that a preoperative insulation with a commercial insulation material (Thermoflect™, TSCI, Amersfoort, NL) leads to a lower incidence of perioperative hypothermia in general anesthesia. The second hypothesis is, that an active prewarming (Thermoflect™ with Mistral Air™, TSCI, Amersfoort, NL) is associated with a more less incidence of periopative hypothermia.
Antibiotherapy During Therapeutic Hypothermia to Prevent Infectious Complications
Ventilator-associated PneumoniaCardiac Arrests With Shockable Rhythm2 moreMild therapeutic hypothermia is currently recommended in management of cardiac arrests with shockable rhythm. In mechanically ventilated patients who were resuscitated after out-of-hospital cardiac arrests, mild therapeutic hypothermia side effects are conductive for infectious complications and especially for ventilator-associated pneumonia (VAP). Despite high incidence of VAP and other infectious complications, it is not currently recommended to use antibiotic prophylaxis on the responsible germs. Yet VAP incidence could be decreased if an antibiotic therapy was systematically given to patient treated with mild therapeutic hypothermia after a cardiac arrest. Several retrospective studies showed less infectious complications but also decreased morbidity and mortality related to these complications when antibiotic therapy was given early to patients treated with therapeutic hypothermia after cardiac arrest.
Randomized Controlled Trial of Long-term Mild Hypothermia for Severe Traumatic Brain Injury
Brain InjuriesCraniocerebral TraumaThis study is a prospective multi-centre randomized trial to compare the effect of long-term mild hypothermia versus routine normothermic intensive management in patients with severe traumatic brain injury. The primary hypothesis is that the induction of mild hypothermia (maintained at 34-35℃) for 5 days will improve the outcome of patients at six months post injury compared with normothermia.
A Pilot Study of Intra-arrest Therapeutic Hypothermia in Patients Suffering Non-Traumatic Out of...
Out-of-Hospital Cardiac ArrestThe objective of this study will be to assess the frequency of return of spontaneous circulation (ROSC), survival to admission, survival to discharge from the hospital, and neurologic function at time of discharge from the hospital among patients experiencing out of hospital cardiac arrest randomized to receive either intra-arrest induction of therapeutic hypothermia (IATH) or post-arrest therapeutic hypothermia (TH).
Duration of Hypothermia for Neuroprotection After Pediatric Cardiac Arrest
Cardiac ArrestBrain InjuryIn this study, children who survive cardiac arrest will be evaluated whether 24 or 72 hours of whole body hypothermia (cooling) during recovery is better to help prevent brain injury and improve outcome. The investigators will also test the safety of cooling patients for 24 and 72 hours. The investigators hypothesize that 72 hours of cooling will be more beneficial than 24 hours without compromising safety.
