Fever is a common clinical symptom in patients with postoperative scoliosis. However, there are rare reports of immediately fevers occurring following operative procedures.
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.
The goal of this interventional clinical study is to investigate the use of mild therapeutic hypothermia for preservation of residual hearing in cochlear implant surgery. The main questions the trial aims to answer are: 1. Is mild therapeutic hypothermia safe for use during cochlear implantation? 2. Is mild therapeutic hypothermia effective at preserving residual hearing after cochlear implantation? Participants will receive mild therapeutic hypothermia therapy during cochlear implant surgery. Researchers will compare results from those receiving the therapy to those from a control group (individuals receiving no therapy).
Background An accurate measurement of the core body temperature (CBT) is of pivotal importance in the management of severely hypothermic patients. For instance, triage decisions for or against extracorporeal rewarming of hypothermic patients in cardiac arrest strongly depend on CBT. CBT measurement with an oesophageal probe is currently considered the gold standard in hypothermic patients with a secured airway in the prehospital setting, with the tip of the probe placed into the distal third of the oesophagus (i.e., posteriorly to the heart and distal to the tracheal bifurcation). However, the correct placement of the probe tip cannot be verified in the prehospital setting, and it is unknown how incorrect placement affects temperature readings. Hypothesis and aim The investigators hypothesise that an incorrect placement of the oesophageal temperature probe tip could lead to inaccurate measurements (i.e., temperature readings not reflecting the real CBT). Particularly, a tip location too high in the oesophagus in close proximity to the trachea could lead to falsely low temperature readings, especially when the patient is ventilated with cold air. The aim of the proposed study is to investigate the influence of oesophageal temperature probe tip location on CBT measurement. Methods Experimental, interventional study on 16 healthy volunteers. During the test oesophageal temperature is measured while participants are breathing ambient air first at 20°C (baseline) followed by cold (-20°C) ambient air in supine position for 20 minutes each test in an environmental simulator (terraXcube). Each participant repeats the 20-min test two times with the oesophageal temperature probe tip placed either in the lower third of the oesophagus (i.e., correct position) or too high in the oesophagus, i.e. behind the trachea.
This study is a prospective, observational, single-center study to assess the correlation between rs-fMRI measures and clinical measures of standard MRI, NIRS, EEG and clinical scores. The target population was neonates with HIE referred to MRI after hypothermia treatment, which was initiated within 6 hours of birth, continued for 72 hours and followed by a slow rewarming period of 6-12 hours. A one-year clinical and imaging follow-up is planned. As the aim of the present study is to assess the predictiveness of the outcome one year after the HIE event, no follow-up is planned.
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.
Massively bleeding trauma patients have higher odds of mortality, increased hospital length of stay, and increased need for transfusion if they become hypothermic. Hypothermia is independently associated with mortality in traumatically injured patients due to its negative physiologic effects on hemostasis, cardiorespiratory and renal function. Current warming strategies increase the logistical difficulty of transferring patients (which is frequent during the initial hours of trauma care) or must be changed at frequent intervals. Prehospital, military, and intraoperative studies have suggested chemical warming blankets as a pragmatic strategy to manage hypothermia. A recent pilot study (manuscript under review) at our institution demonstrated the feasibility of using the Ready-Heat® (TechTrade LLC, Orlando, FL, USA) chemical heating blanket in the initial phases of hospital care in bleeding trauma patients requiring a mass hemorrhage protocol (MHP). These self-warming blankets provide warmth over 8 hours at up to 40 degrees Celsius, carrying the advantage of portability with no continuous electric power requirement. Furthermore, the Ready-Heat blanket may be more effective than current strategies for rewarming patients at high risk of developing hypothermia. STAYWARM-2 will be the first randomized controlled trial performed in-hospital to evaluate a self-warming blanket to address hypothermia in massively bleeding trauma patients within the initial hours of hospital arrival. This study will help to determine the efficacy and feasibility of using chemical heating blankets for hypothermia in the early hours of hospital care. This has potential to reduce the overall workload of direct care clinicians, freeing them for other patient care duties. Additionally, the intervention may achieve enhanced thermoregulation compared to current strategies, improving patient care and comfort, and avoiding the clinical complications related to hypothermia. Findings from this preliminary study may provide data for a future grant to launch a larger randomized controlled trial in the prehospital/in-hospital trauma setting to optimize the care of patients at risk of developing hypothermia.
A significant medical risk associated with hypothermia during exercise in a cold environment cardiac arrhythmia due to a possible autonomic conflict. However, little is known about the changes in heart rate and cardiac function after prolonged cold water swimming. The investigators propose to measure the changes in core temperarure during and after a cold water swim at at a water temperature below 15.5°C qualifying for English Channel swim and to test the association with changes in heart rate variability, resting electrocardiogram and left ventricle function.
In this study, it is aimed to reveal the effect of the use of heated socks to be developed as wearable technology by providing temperature control on body temperature, comfort perception level and shivering development in healthy volunteers and this purpose constitutes the unique value of the project. The research was planned as a prospective, two-arm (1:1), randomized controlled, double-blind study. The population of the study will consist of 4th year nursing students consisting of an average of 250 people who will enroll in the fall semester of the 2024-2025 academic year. As a result of the power analysis performed in the G*Power program, the sample will consist of 70 healthy volunteers, at least 35 in each group. In the study, data will be collected with the "Descriptive Characteristics Form" and "Hypothermia Monitoring Form (Shivering Level Diagnosis Form and Temperature Comfort Perception Scale)" which includes the descriptive information of healthy volunteers. Healthy volunteers will fill out the "Introductory Characteristics Form" and "Hypothermia Monitoring Form" before being taken to the Faculty of Nursing Skills Laboratory for the application. Before the volunteers are taken to the single rooms in the laboratory, the environment will be cooled for 30 minutes with the air conditioner in the room so that the temperature is 21oC. The study group will wear socks developed with wearable technology and the control group will wear socks with the same appearance. The healthy volunteer will be asked to lie motionless on the bed for 60 minutes in a single room. Body temperature (with Braun tympanic thermometer), shivering level and temperature comfort perception will be recorded on the "Hypothermia Monitoring Form" when all healthy volunteers are taken to the Skills Laboratory, at 15 minutes, 30 minutes and 60 minutes, and when they leave the laboratory. The research data will be analyzed in a computer environment. Descriptive variables of healthy volunteers included in the study will be expressed as mean±standard deviation and median (maximum minimum), percentage and frequency. Changes in body temperature measurements obtained after wearing socks to be developed with wearable technology, repeated measurements, analysis of variance (Repeated ANOVA) if parametric, Friedman test if non-parametric, and post-hoc test will be used in intra-group multiple comparison analysis as further analy
