Filter by:Acute ischemic stroke (AIS) has been one of the major causes of global mortality and morbidity. The superiority of endovascular therapy (EVT) over standard medical therapy in treating AIS due to large vessel occlusion (LVO) in the anterior circulation has been widely accepted. However, a critical concern is that even with an extremely high rate of successful recanalization (the modified thrombolysis in cerebral infarction [mTICI] score 2b-3) around 90%, nearly half of the patients failed to benefit from EVT. So, adjunctive therapy of EVT for neuroprotection is required. From the previous domestic and foreign literatures, hypothermia can prevent and treat secondary injury caused by ischemia-reperfusion injury and cerebral edema of acute cerebral ischemia, so as to achieve the role of neuroprotection. In this study, intravascular cooling was performed as soon as possible with careful temperature control in patients receiving thrombectomy. The temperature was controlled at 33° C for 48-72 hours. This parallel controlled study is to systematically evaluate the feasibility and safety of adjunctive therapy using early intravascular hypothermia in AIS patients receiving mechanical thrombectomy. The results will clarify a potential modality for neuroprotection and hopefully provide new evidence in improving patient prognosis.
In this study, patient groups in which normothermia is preserved by using multiple active warming methods in the intraoperative period in AIS surgery, followed by a single compressed air blowing system and allowed mild to moderate hypothermia were compared.
During the cesarean section; Hypothermia can be seen due to reasons such as anesthesia, premedication drugs, cold operating room environment, exposure of tissues and organs, and use of cold intravenous fluids. Hypothermia associated with cesarean may affect maternal and fetal health negatively. As a result of hypothermia, coagulopathy, infection, undesirable cardiac events that cause an increase in oxygen consumption, delay in postoperative recovery and wound healing, postoperative nausea and vomiting, chills and relief may be observed in the mother. Newborns born from hypothermic mothers have lower body temperature, pH and Apgar scores. It is important to evaluate all women in terms of risk factors in the preoperative period in the prevention of hypothermia and complications related to hypothermia. Prevention of hypothermia, which has negative effects on maternal and newborn health, is one of the risks that the nurse can address independently. Therefore, this research; In order to determine the effect of heating different body areas using compressed air heating technique during cesarean section on hypothermia, tremor, thermal comfort, postpartum comfort and maternal satisfaction, a parallel group was planned as a randomized controlled trial. The study is planned to be conducted in Hacettepe University Adult Hospital Gynecology and Obstetrics Department delivery room and obstetrics service. Research data, Introductory Information Form (Appendix 1), Obstetric and Postpartum Features Form (Appendix 2), Patient Monitoring Form (Appendix 3), Termal Comfort Perception Scale (Appendix 4), Shivering Level Diagnostic Form (Appendix 5), LATCH Breastfeeding The Diagnostic and Measurement Tool (Appendix 6) will be collected using the Visual Analogue Scale (Appendix 7) and the Thermal Comfort Scale that will be developed by the researchers. Pregnant women who meet the inclusion criteria will be included in the research. Women will be divided into 4 groups as the lower extremities are heated, the upper extremities are heated, the whole body is heated, and the control group. According to the group of women; It will be heated 30 minutes before surgery and 30 minutes after surgery with lower limb, upper limb or whole body. Women in the control group will not be heated.
The common practice of conventional cold storage (CCS) organ preservation has changed little since the initial introduction of the original University of Wisconsin (UW) organ preservation solution in the late 1980s. CCS relies on hypothermia to decelerate metabolism and reduce oxygen demand in order to prolong the time of ischemia without rapid functional graft impairment, therefore merely delaying graft damage. While CCS only prolongs storage time and limits the damage sustained during the period of cold ischemia, ex-vivo machine perfusion (MP) appears to be capable of reversing some of these effects. Currently, two main paradigms prevail in the clinical approach to liver allograft MP: hypothermic oxygenated MP (HOPE) may be seen as a dynamic alternative of the traditional organ preservation based on hypothermia-induced deceleration of metabolism, which aims to combine the positive effects of hypothermia observed in classical cold storage (e.g. technical simplicity, relative safety, decreased metabolism) with the positive effects of dynamic preservation (e.g. controlled sheer stress mediated gene activation, removal of metabolites, transport of oxygen and ATP recharging). Normothermic perfusion (NMP) aims at re-equilibration of cellular metabolism by preserving the organ at physiological temperatures whilst ensuring sufficient oxygen and nutrient supply. In both approaches, the perpetual circulation and moderate shear-stress sustain endothelial functionality. While past and current clinical trials were designed to compare different MP approaches with CCS as the clinical standard, a direct comparison between different end-ischemic MP techniques (HOPE versus NMP) is still lacking. The purpose of this study is to test the effects of end-ischemic NMP versus end-ischemic HOPE technique in a multicentre prospective randomized controlled clinical trial (RCT) on ECD liver grafts in DBD liver-transplantation (HOPE-NMP). Two-hundred-thirteen (n = 213) human whole organ liver grafts will be submitted to either 4-24 hours of NMP (n = 85) or 2-3 hours of HOPE (n = 85) directly before implantation and going to be compared to a control-group of patients (n = 43) transplanted with static cold storage preserved ECD-allografts. Primary (surgical complications as assessed by the comprehensive complication index [CCI]) and secondary (among others laboratory values, graft- and patient survival, hospital costs, hospital stay) endpoints are going to be analysed.)
When taking care of an emergency patient (Emergency Reception Service: UAS and Urgent Medical Assistance Service: SAMU), the installation of a peripheral venous route (VVP) is an important step. The benchmark method is the most widely used technique. This vascular access will allow the necessary therapy to be delivered quickly and efficiently. This can be difficult and sometimes doomed to failure for reasons related both to the patient (venous capital not very visible / felt or limited due to the profile of the patient), or sometimes also for reasons related to the patient. environment (limited lighting, difficult patient access). The only current alternatives lie in the use of a device such as the Intra-Bone Device (IID) or the installation of a central venous line. On the other hand, these alternatives are particularly invasive and / or very algogenic. There are other techniques, which are more affordable and "transportable" outside the hospital. Indeed, trans-illumination with a very short training seems to be a particularly interesting alternative. It allows, thanks to LEDs in contact with the skin, to backlight the superficial veins. It is proposed through this project to evaluate this tool for a category of patients considered "difficult" to infuse, both within hospital and outside hospital. The main objective of the study is to assess the effectiveness of the transillumination device, compared to the absence of such a device, on the placement of a peripheral venous line (PVP) in patients with a difficult vascular approach and managed in the emergency room and whose clinical condition does not require the installation of an intraosseous device. This is a multicenter, prospective, controlled, randomized and open clinical study, according to a cross-over design. The intervention evaluated is the placement of a PVR using the trans-illumination device. The control intervention is the placement of a PVR without this device, according to the reference method, which is the benchmark method. 400 patients presenting to the emergency room will be included in the centers of Nancy, Toul and Pont-à-Mousson. Depending on their randomization group, nurses will perform peripheral venous insertion by the transillumination method or by the control method.
Transient Acetaminophen Induced Hypothermia in Pediatrics Population Undergoing General Anesthesia
The aim of our study is to evaluate the feasibility of applying transcutaneous CO2 monitoring (tcPCO2) in neonates receiving therapeutic hypothermia and to quantify the agreement between tcPCO2 and PCO2 in this population with or without respiratory support. Although, transcutaneous measurement of CO2 tension is the most commonly used non-invasive CO2 monitoring system in neonatal intensive care, to date tcPCO2 technique has not been evaluated systematically or used routinely in the intensive care of infants with neonatal encephalopathy receiving hypothermia treatment.
The purpose of this prospective randomized controlled study is to compare the efficiency in preventing perioperative hypothermia of a continuous active prewarming combined with active intraoperative warming versus passive prewarming plus intraoperative warming for short outpatient surgery.
The study is designed to retrospectively assess the risk factors associated with intra-operative hypothermia in patients undergoing total knee arthroplasty from January 2016 to December 2017 at Aga Khan University and also understand it's impact on post-operative outcomes.
Some patients with COVID have abnormally high carbon dioxide and low oxygen levels despite being on the ventilator. The hypothesis of the study is that the application of mild hypothermia to patients with COVID will decrease their metabolic rate and improve their oxygenation and carbon dioxide levels.
