ReviewImpact of computerized information systems on workload in operating room and intensive care unit.
The number of operating rooms and intensive care departments equipped with a clinical information system (CIS) is rapidly expanding. Amongst the putative advantages of such an installation, reduction in workload for the clinician is one of the most appealing. ⋯ The hypothesis that a third generation CIS can reduce documentation time for ICU nurses and increase time they spend on patient care, is supported by recent literature. Though it seems obvious to extrapolate these advantages of a CIS to the anesthesiology department or physicians in the intensive care, studies examining this assumption are scarce.

ReviewMachine learning techniques to examine large patient databases.
Computerization in healthcare in general, and in the operating room (OR) and intensive care unit (ICU) in particular, is on the rise. This leads to large patient databases, with specific properties. ⋯ Although the number of potential applications for these techniques in medicine is large, few medical doctors are familiar with their methodology, advantages and pitfalls. A general overview of machine learning techniques, with a more detailed discussion of some of these algorithms, is presented in this review.

ReviewThermal management during anaesthesia and thermoregulation standards for the prevention of inadvertent perioperative hypothermia.
Incidence of inadvertent perioperative hypothermia is still high, and thus thermoregulatory standards are warranted. This review summarizes current evidence of thermal management during anaesthesia, referring to recognized clinical queries (temperature measurement, definition of hypothermia, risk factors, warming methods, implementation strategies). Body temperature is a vital sign, and 37 degrees C is the mean core temperature of a healthy human. ⋯ The patient's body temperature should be above 36 degrees C before induction of anaesthesia, and should be measured continuously throughout surgery. Active warming should be applied intraoperatively. Postoperative patient temperature and outcomes should be evaluated.

ReviewTherapeutic hypothermia after cardiac arrest and myocardial infarction.
About 17 million people worldwide die from cardiovascular diseases each year. Impaired neurologic function after sudden cardiac arrest is a major cause of death in these patients. Up to now, no specific post-arrest therapy was available to improve outcome. ⋯ A broad implementation of this new therapy could save thousands of lives worldwide, as only 6 patients have to be treated to get one additional patient with favourable neurological recovery. At present, myocardial reperfusion by thrombolytic therapy or primary PCI as early as possible is the most effective therapy in patients with acute myocardial infarction. Mild therapeutic hypothermia might be a promising new therapy to prevent reperfusion injury after myocardial infarction, but its use in daily clinical routine cannot be recommended with the available evidence.

ReviewHyperthermia during anaesthesia and intensive care unit stay.
Nosocomial hyperthermia (fever) occurs in about 30% of all medical patients at some time during their hospital stay. In patients admitted to the intensive care unit with severe sepsis the incidence of hyperthermia is greater than 90%, while in a specialized neurological critical care unit the incidence is reported as 47%. In contrast, hyperthermia during anaesthesia is rare owing to the impairment of thermoregulation by anaesthetic agents. This article is designed to give an overview on the various causes of hyperthermia with special emphasis on fever during general and regional anaesthesia in general and neurological critical care patients.
