Active clinical trials for "Hypothermia"

The goal of this observational study is to compare frequency of intraoperative hypothermia between fragilitly groups of eldery patients who underwent orthopedic surgical procedures. It aims to answer those questions: İs there any difference between fragility groups in terms of hypothermia frequency during orthopedic surgical procedures? Are there any other factors that influence the frequency of hypothermia such as age, body mass index, room temperature etc. ? Participants body temperature before anestesia application,and before surgery had started was measured and measurament was done during whole procedure. Measuraments had been done by tympanic thermometer.

Hypothermia is common in patients undergoing general anesthesia. There have been several negative outcomes reported. Zero heat flux is a non-invasive method for measurement of body core temperature. The aim of this study is to see if this method is comparable in terms of correlation, accuracy, precision and practicability to commonly used sublingual and nasopharyngeal temperature monitoring.

We aim that uncovering patients during induction of general anesthesia does not decrease core body temperature in pediatric patients.

Patients resuscitated from a cardiac arrest undergo therapeutic hypothermia as a treatment option. Measuring the cardiac output in these patients is sometimes important, but difficult, as these patients require an invasive device for measurement. Recently, a non-invasive device based on pulse-contour analysis of the arterial pulse was developed (the Vigileo). Hypothermia changes the pulse contour, so the performance of the Vigileo in patients with induced therapeutic hypothermia is not known. Therefore we conduct this observational study in which the cardiac output of the patients is measured with the traditional method and the Vigileo simultaneously.

Perioperative hypothermia is associated with many complications, including surgical site infections, delayed wound healing, coagulopathy, prolonged hospital and intensive care unit length of stay. Perioperative close monitoring of the body temperature is important, and this is recommended by many clinical practice guidelines. In this study the investigators aimed to detect the incidence of perioperative hypothermia in adult patients in the operating room, and to detect the possible associated risk factors.

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.

A single-center, prospective case series clinical study consecutively enrolling up to 10 patients with expected duration of 12 months or less. The study objectives are to evaluate retention and the feasibility of integrating therapeutic hypothermia using the ZOLL IVTM System.

Subjects will be admitted to hospital the evening prior, or the morning of surgery, whereupon they will undergo standard admission processes, including pre-operative assessment by the anaesthetist assigned to that list (One of the two study authors). The anaesthetist will then explain the study again, reiterating the potential risks and benefits of the study to the patient themselves, and to the population as a whole. Consent will be sought at this point. Patients will be transferred to theatre, anaesthetised and operated on as per normal practice. Inclusive of this, in accordance with NICE guidelines, patients will have a nasal or oesophageal Doppler probe inserted to accurately measure core temperature. At this point, patients enrolled in the study will have temperature measurements taken every minute from the oesophageal probe and non-contact thermometers. If the patients requested it previously, they will be informed of the results of the study at a later date. Statistics will then be carried out on the data to compare accuracy of the two novel methods to the oesophageal probe.

Aims:- Primary: To identify the incidence of intra-operative and post-operative hypothermia Secondary: To identify factors contributing to peri-operative hypothermia. To identify current anaesthetic practice in peri-operative temperature monitoring, use of active/warming measures by anaesthetists in various hospitals. To increase awareness of the problem of IPH and guidelines available.

To evaluate the significance of free-plasma deoxyribonucleic acid (DNA) and plasma histones in cardiac arrest patients.
