Measurement of cerebral oximetry by near-infrared spectroscopy provides continuous and non-invasive information about the oxygen saturation of haemoglobin in the central nervous system. This is especially important in the case of patients with traumatic brain injuries. Monitoring of cerebral oximetry in these patients could allow for the diagnosis of inadequate cerebral oxygenation caused by disturbances in cerebral blood flow. It could enable identification of episodes of hypoxia and cerebral ischemia. Continuous bedside measurement could facilitate the rapid diagnosis of intracranial bleeding or cerebrovascular autoregulation disorders and accelerate the implementation of treatment. However, it should be remembered that the method of monitoring cerebral oximetry by means of near-infrared spectroscopy also has its numerous limitations, resulting mainly from its physical properties. This paper summarizes the usefulness of monitoring cerebral oximetry by near-infrared spectroscopy in patients with traumatic brain injury, taking into account the advantages and the disadvantages of this technique.
BACKGROUND:Long-term clinical observations have shown that anxiety disorders influence the etiopathogenesis of ischemic heart disease (IHD) in women. The aim of this study was to determine the characteristics of the structure of overt and covert anxi...
Robotic surgery has become increasingly popular over the last 30 years. This technique is particularly attractive due to its minimally invasive nature, high precision compared to open and laparoscopic techniques, less postoperative pain, shorter hospital stay for patients, and faster recovery. For an anesthesiologist, robot-assisted operations involve numerous challenges resulting from the surgical technique. The most important problems during anesthesia include changes in physiology resulting from the development of pneumoperitoneum and a steep Trendelenburg position. This review discusses problems that may be encountered by an anesthesiologist performing anesthesia during robotic surgery.

Introduction: Risk factors for ischemic heart disease (IHD) are very numerous and not fully defined. In addition to classic risk factors, different factors are also distinguished, among them psychological aspects chich have rarely been subject to detailed analyses. Objective: The aim of...
Tlen jest najczęściej i najpowszechniej używanym lekiem. Tlenoterapia stosowana jest wśród wentylowanych mechanicznie pacjentów oddziałów intensywnej terapii, w okresie okołooperacyjnym, a także u pacjentów wymagających suplementacji tlenem, przebywających na innych oddziałach szpitalnych. Do głównych metod monitorowania poziomu utlenowania krwi w organizmie należą oznaczanie gazometrii krwi tętniczej oraz pulsoksymetria. Nowym parametrem pozwalającym na monitorowanie gospodarki tlenowej jest indeks rezerwy tlenowej (ORi). ORi umożliwia łatwe, nieinwazyjne, przyłóżkowe monitorowanie poziomu rezerwy tlenowej organizmu. Indeks rezerwy tlenowej odzwierciedla wartości ciśnienia parcjalnego tlenu we krwi tętniczej (PaO2) w zakresie 100–200 mm Hg. Pozwala on na wykrywanie łagodnej hiperoksji, co umożliwia bezpieczne stosowanie niższych stężeń tlenu w mieszaninie oddechowej. Jest również przydatnym narzędziem w przewidywaniu zagrażającej hipoksji. W artykule omówiono przydatność monitorowania indeksu rezerwy tlenowej w różnych sytuacjach klinicznych z codziennej praktyki anestezjologicznej.
