Filter by:Hypothermia that may develop in the perioperative period is associated with many adverse clinical outcomes. In particular, pediatric patients were more susceptible to hypothermia and related complications such as respiratory distress, metabolic acidosis, hypoglycemia, hypoxemia, cardiac disorders, coagulopathy, and wound infection than adults. In this study, the effect of preoperative carbohydrate-rich feeding on temperature regulation in pediatric patients was investigated.
This study compares the effectiveness of a new layered thermal insulation system (SIT-3c) versus the traditional thermal body protection (warmed forced air system) for patients under total knee arthroplasty, during the intra-operative phase.
Perioperative hypothermia carries high risk of associated complications. In the observational study, the standard perioperative temperature management will be evaluated and the influence of the hypothermia on the coagulation system according to routine coagulation testing in combination with ROTEM will be evaluated.
36 patients American society of anesthesiology (ASA) physical status I,II and III undergoing general anesthesia for elective transurethral resection of the prostate (TUR-P) surgery will be included in the study. Patients will be randomized into two groups; first group(control group) and second group (forced-air warming). Resistive heating will start when patients are transferred to the operating room table; forced-air warming will start before preoperative 30 minute.
The study should evaluate how long patients undergoing major abdominal surgery under combined general/epidural anaesthesia have to be actively warmed preoperatively to prevent perioperative hypothermia and postoperative shivering. 99 patients will receive forced-air skin-surface warming for different duration. Body temperature will be measured at the tympanic membrane. The investigators hypothesize that active warming before starting the epidural anaesthesia will decrease the incidence of perioperative hypothermia.
Although 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.
