Filter by:The overarching aim of this project is to determine the optimum enteral and parenteral nutrition strategy for newborns with Hypoxic Ischaemic Encephalopathy (HIE) during and after therapeutic hypothermia. To do this the investigators will perform two primary comparisons: 1. ENTERAL: to determine whether any enteral (milk) feeding, when compared to withholding enteral feeding (no milk), during therapeutic hypothermia, is associated with a difference in the incidence of necrotising enterocolitis. 2. PARENTERAL: to determine whether provision of intravenous dextrose, when compared to provision of parenteral nutrition, during therapeutic hypothermia, is associated with a difference in the incidence of blood stream infection. The investigators will use de-identified data held in an established research database called the National Neonatal Research Database (NNRD) and we will use the potential outcomes framework with application of propensity scoring to define matched subgroups for comparison.
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.
In patients with ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary angioplasty (PCI) P2Y12 receptor (P2Y12r) inhibition should be achieved as soon as possible. Resuscitated STEMI-patients receiving targeted temperature management (TTM, therapeutic hypothermia) after cardiac arrest, however, show deteriorated and delayed early response to available oral P2Y12r inhibitors. Therapeutic hypothermia attenuates the drugs' effectiveness by reducing its gastrointestinal absorption and metabolic activation. Acute stent thrombosis is 5-fold increased after angioplasty following resuscitated cardiac arrest because of insufficient early platelet suppression. Thus, aggressive antiplatelet strategies are needed to achieve optimal platelet suppression during PCI in those patients. The first intravenous P2Y12r inhibitor, cangrelor, has recently received marketing authorization for the acute treatment of STEMI. We hypothesize that add-on antiplatelet therapy with intravenous Cangrelor on-top of standard dual anti platelet therapy (DAPT) with Prasugrel or Ticagrelor is superior to standard antiplatelet therapy alone in terms of suppressing ADP-dependent platelet activation in resuscitated STEMI-patients receiving TTM.
Patient's sublingual temperature was measured postoperatively on entry to the recovery room.
Glyceryl trinitrate is used in coronary artery bypass grafting surgery. This surgery frequently employs hypothermic cardiopulmonary bypass, where the whole body is cooled down to 28-32 °C to arrest the heart, and protect the organs from ischemic insult. When the cardiac repair or grafting is done, the body is warmed to 37 °C. During this "rewarming period", the heart has to beat against the vessels, all of which are constricted due to hypothermia. To overcome this constriction of the vessels, and decrease the workload of the heart, glyceryl trinitrate is infused. This drug causes significant dilatation in arteries and veins, which allows the heart to pump the blood with less force. The dilatation of the vessels also allows the body to rewarm more easily. The investigators' concern is whether increased infusion rates of glyceryl trinitrate may cause uncontrolled rewarming of the brain or not. The investigators will measure the temperature of the brain using a temperature probe located in the nasal cavity. The temperature will be recorded at each minute during the the rewarming period. Results of two commonly used infusion rates of glyceryl trinitrate will be compared.
Background Major spinal surgery tend to be lengthy with an increased risk of hypothermia. A quality improvement project of patients undergoing major spinal surgery showed that 67 % were hypothermic at the beginning of surgery. Several patients expressed a feeling of coldness at the arrival of the operating theatre. Aim To evaluate if Bairhuggers Full Access Underbody blanket can prevent hypothermia at initiation if used as prewarming and intraoperative warming compared to the results from the local quality improvement project. In addition we aim to explore patients´ experiences of comfort in relation to their temperature. Method Temperature of patients undergoing major spinal surgery (n=30) will be assessed at arrival to the theatre, after insertion of bladder catheter, at the start and end of surgery using a bladder temperature. The patients´ experiences of comfort will be evaluated with a 5 point Likert at the arrival to the operating theatre and after ten minutes of active prewarming with Bairhuggers Full Access Underbody blanket. Preoperatively ten randomly chosen patients will be observed and later interviewed in order to obtain further information regarding their experiences of comfort in relation to their temperature. Conclusion and perspectives By increasing the investigators knowledge on Bairhuggers Full Access Underbody blanket and its effects in preventing hypothermia as well as gaining insight to patients´ experiences of comfort in relation to temperature, the investigators anticipate to improve pre-anesthetic care and minimize risk factors associated with hypothermia for patients undergoing major spinal surgery.
The purpose of the study is to assess the temperature changes that take place throughout the body in a real world setting, when a patient is given general anaesthesia. Specifically we will investigate the movement of body heat from the core to the peripheries at the beginning of surgery. This will be measures with a series of temperature sensors and infrared thermography
Inadvertent perioperative hypothermia is an unintentional drop in core body temperature below 36°C. Intraoperative hypothermia can lead to serious clinical complications such as, myocardial ischemia, coagulopathy, immunosuppression, and surgical wound infection. Hypothermia develops easily during surgeries that require irrigation fluid, such as laparoscopic surgery and transurethral resection of the prostate. Although isothermic irrigation fluid was suggested to prevent perioperative hypothermia, it can be difficult to warm a large volume of irrigation fluid. Re-distribution after induction of anesthesia is the most important cause of perioperative hypothermia. The extent of re-distribution is proportional to the gradient between the core and peripheral compartments. Pre-warming increases the heat content of the peripheral thermal compartment, reducing the gradient for redistribution. Recently, A recent-meta analysis suggested that as a single strategy, preoperative forced air warming had significant benefits than other warming methods. Also, it was reported that only 20 (or even 10) min of pre-warming mostly prevented patients from perioperative hypothermia under general anesthesia. However, few studies have examined whether short time pre-warming can reduce hypothermia due to a large amount of irrigation fluid during surgery under spinal anesthesia. The purpose of this study is to assess whether the application of preoperative forced air warming set to high temperature (> 43°C) for brief period can prevent hypothermia or shivering during procedures requiring large volumes of cold irrigation.
A prospective pharmacokinetic (PK), pharmacodynamic (PD) and pharmacogenetic (PG) observation study, including the PK/PD/PG relationship, in fentanyl and clonidine administered for analgesia and sedation to term newborn asphyxiated infants receiving hypothermic treatment in the NICU.
The purpose of the study is to measure patient- temperature in the perioperative period of patients undergoing plastic surgery in an ambulatory surgical unit. This study will evaluate if active warming with self-warming blanket (Easywarm®) is as effective as active warming with forced-air blanket (BairHugger®). Second the study will evaluate if one or both methods is effective in preventing perioperative hypothermia.
