Filter by:The overall hypothesis is that better adherence to Kangaroo Mother Care (KMC) in combination with existing WHO thermoregulation care will reduce the incidence of moderate hypothermia (32-36 degrees C) or severe hypothermia (<32.0 degrees C) in preterm infants (32-36 6/7 weeks of gestational age) when compared with routine WHO thermoregulation alone.
Mild 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.
The purpose of this study is to investigate, if the haemostasis is impaired in cardiac arrest patients during therapeutic hypothermia compared with normothermia.
The application of active warming to patients whether awake or under general anesthesia has been proven safe in numerous studies and it is common practice to use warmers. The warmers are commonly used with both the supplied blankets and also with hospital blankets. Subjects receiving standard care will not benefit from this study. Subjects in the investigational group may benefit in several ways: - Increased comfort in the pre-operative period by being warmer - Decreased incidence of mild hypothermia - Possible decreased incidence of transfusion with less bleeding - Possible decreased pain and discomfort in the Post-Anesthesia Care Unit (PACU) - Possible shorter stay in the PACU and overall Length of Stay (LOS) - Possible decreased risk for surgical site infection
Getting cold (not maintaining normothermia) around surgery (perioperative period) leads to many negative outcomes for patients including increased wound complications, abnormal heart rhythms and increased blood loss. These all lead to increased length of hospital stay and higher requirements for post operative monitoring. These add to around $3500 of extra costs per patient. The investigators aim to study the effects of a warming device, placed around the patient's legs and/or feet, to determine it's safety, efficacy and eventually compare to the current gold standard of a forced air warming blanket. Forced air warming has been associated with the spread of germs over the surgical field. Hence the need for warming equipment that won't do that.
Background When a patient is anesthetised and undergoes an operation, their body temperature falls. Managing a body temperature properly by keeping it within normal limits has been shown to improve recovery from surgery. A vital part of managing temperature is being able to measure it properly. There are several ways of doing so, which consist of invasive methods such as temperature probes in the oesophagus and bladder, and non invasive methods such as infrared scanners and ear canal probes. During an operation, temperature changes as small as 0.5 °C can affect outcomes but, currently, only invasive methods are reliable enough to detect this. Oesophageal probes can't be used in patients who are not anaesthetised during their operations, and it is inappropriate to insert a urinary catheter should it not be otherwise needed. The purpose of this study is to look at two new methods of measuring a patient's temperature which would help us in these situations. The first is called zero-flux thermometry and involves placing an adhesive pad to the forehead, which gives constant measurement of a patient's core temperature. The second involves swallowing an ingestible capsule that is no bigger than a normal pill. This technique has been very useful in research tracking a patient's core temperature as they are transferred through different areas over a longer period of time. Whilst these two methods are potentially very useful, they have never been tested on hospital patients. Aims: The investigators want to determine whether readings from these thermometers are accurate enough to be used in patients before, during and after surgery. Should they prove to be sufficiently accurate it will allow us to improve patient care through both clinical practice and research. Plan: During operations, temperature is routinely measured in line with NICE guidelines with a thermometer placed in the nose or oesophagous. The investigators will not be changing routine practice in any way, but checking measurements from the new devices against the proven, routine ones. The investigators plan to record measurements from each device every minute throughout the operation in 20 patients. The investigators will then perform statistical tests to check their accuracy. Study Hypothesis: Zero flux and ingestible thermometers are not significantly different at detecting patients body temperature than oesophageal temperature probes
Background: Hypothermia is common during general and regional anesthesia even when active warming measures are taken. The existing literature shows that, in pregnant patients, the use of forced air-warming during cesarean section under spinal anesthesia does not prevent maternal hypothermia. Therefore, this study aimed to establish the efficacy of a pre-warming system, initiated 30 minutes before the onset of spinal anesthesia and during surgery, in pregnant women subjected to elective cesarean delivery. Methods: Forty healthy pregnant patients undergoing elective cesarean section with spinal anesthesia were allocated to the control group (Gcont, n = 20), without the use of a thermal gown, and to the gown group (Ggown, n = 20), with the use of a thermal gown in the preoperative care unit, 30 minutes before spinal anesthesia installation and during surgery. After the anesthesia, the thermal gown was moved from the regular position and placed over the chest and upper limbs, as an upper body blanket, and maintained throughout the study. The following variables were observed: preoperative and operative room temperature, hemoglobin saturation, heart rate, arterial pressure, tympanic temperature in the preoperative care unit room (baseline) and at 0, 15, 30, 45 and 60 minutes after spinal anesthesia. Repeated Measure ANCOVA compared temperatures of each group, adjusted for baseline values.
This investigation is undertaken to investigate if patient warming with BARRIER® EasyWarm active self-warming blanket differs compared to active warming with forced air warming in terms of core body temperature perioperatively. A non-inferiority, prospective, open-labelled, randomized, parallel investigation. Randomized subjects will receive active warming with BARRIER® EasyWarm or with forced air warming. All subjects may receive rescue warming if their core temperature falls below 35.5°C. Rescue warming is optional and defined as the institution's standard of care to prevent hypothermia. The primary purpose is to investigate if there is a clinically relevant difference in core body temperature between the two treatment groups. A total of 60 subjects will be included in the investigation, i.e. 30 subjects in each treatment group. The number includes a 30% drop-out rate.
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.
This PhD study is a sub study in a randomized clinical controlled multicenter trial named "TTH48" (ClinicalTrials.gov Identifier: NCT01689077). The TTH48 trial examines prolonged mild therapeutic hypothermia ("MTH") at 32-34°C in 24 versus 48 hours with the primary outcome Cerebral Performance Category after 6 month in comatose out-of-hospital cardiac arrest patients. THE OVERALL AIM OF THIS PhD STUDY IS TO INVESTIGATE THE CARDIAC FUNCTION AND THE HEMODYNAMICS BY BIOCHEMICAL CARDIAC MARKERS, ECHOCARDIOGRAPHY, BY ANALYZING THE USAGE OF INOTROPES/VASOPRESSORS AND BY ANALYZING ECG DATA FOR ARRHYTHMIAS IN THE 24 VERSUS 48 HOURS MTH GROUPS.
