A 52-years-old man, who had undergone coil embolization of saccular aneurysm of the brachiocephalic artery, presented with right back discomfort. Diagnosis by computed tomography was difficult because of an artifact from the coils. Angiography, on the other hand, revealed a rupture of the aneurysm, and emergency surgery was performed. A Y-shaped graft was anastomosed to the ascending aorta under partial clamp. Then, one of its branches was anastomosed to the common carotid artery also under partial clamp in an end-to-side fashion...

BACKGROUND: Gly16arg polymorphism of the adrenergic β2-receptor is associated with the elevated cardiac output (Q) in healthy gly16-homozygotic subjects. We questioned whether this polymorphism also affects Q and regional cerebral oxygen saturation (SCO2) during anesthesia in vascular surgical patients. METHODS: One hundred sixty-eight patients (age 71 ± 6 years) admitted for elective surgery were included. Cardiovascular variables were determined before and during anesthesia by intravascular pulse contour analysis (Nexfin) and SCO2 by cerebral oximetry (INVOS 5100C)...

BACKGROUND: Near-infrared spectroscopy (NIRS) is a noninvasive monitoring technique that measures regional cerebral oxygen saturation (rSO2). OBJECTIVES: The primary aim was to compare the output of 2 NIRS-based cerebral oximetry devices, FORESIGHT (CAS Medical Systems Inc, Branford, Connecticut) and INVOS (Covidien, Boulder, Colorado), to venous oxygen saturations from the jugular venous bulb at cannulation and decannulation of the superior vena cava (SVC). Secondary objectives included evaluating correlations of cerebral saturation, as measured by the NIRS devices, with mean arterial blood pressure (MAP), measured by an invasive arterial line, and end-tidal CO2 (ETCO2)...

OBJECTIVES: The purpose of the present study was to assess, by near-infrared spectroscopy with an INVOS oximeter during the vascular occlusion test (VOT), the influence of cardiopulmonary bypass (CPB) on tissue saturation in the thenar muscle. The secondary aim was to compare the effects of propofol and sevoflurane anaesthesia on tissue saturation. METHODS: This was a prospective, randomized, open-label study. Sixty cardiac surgery patients received either propofol or sevoflurane anaesthesia...

INTRODUCTION: Prospectively assess cerebral autoregulation and optimal mean arterial pressure (MAPOPT) using the dynamic relationship between MAP and regional saturation of oxygen (rSO2) using near-infrared spectroscopy. METHODS: Feasibility study of twenty patients admitted to the intensive care unit following a cardiac arrest. All patients underwent continuous rSO2 monitoring using the INVOS(®) cerebral oximeter. ICM+(®) brain monitoring software calculates the cerebral oximetry index (COx) in real-time which is a moving Pearson correlation coefficient between 30 consecutive, 10-s averaged values of MAP and correspond rSO2 signals...

OBJECTIVE: The purpose of this study is to measure peak acceleration forces during interfacility transport; examine whether drops in cerebral oxygenation occurred; and test the associations between cerebral oxygenation, acceleration, and patient positioning. METHODS: A cerebral oximeter (INVOS-5100C; Somanetics, Minneapolis, MN) monitored regional saturation of oxygen (rSO2 [cerebral oxygenation]) in pediatric and neonatal patients (N = 24) transported between facilities by ground ambulance, helicopter, or fixed wing aircraft...

BACKGROUND: The purpose of this multicenter pilot study was to: (1) determine the frequency of regional cerebral oxygen saturation (rScO2) desaturations during cardiac surgery involving cardiopulmonary bypass (CPB); (2) evaluate the accuracy of clinician-identified rScO2 desaturations compared with those recorded continuously during surgery by the near-infrared spectroscopy (NIRS) monitor; and (3) assess the effectiveness of an intervention algorithm for reversing rScO2 desaturations...

PURPOSE: The purpose of this study is to to compare the efficacy of intravaginal culture (IVC) of embryos in INVOcell™ (INVO Bioscience, MA, USA) to traditional in vitro fertilization (IVF) incubators in a laboratory setting using a mild pre-determined stimulation regimen based solely on anti-mullerian hormone (AMH) and body weight with minimal ultrasound monitoring. The primary endpoint examined was total quality blastocysts expressed as a percentage of total oocytes placed in incubation...

A 33 year-old female patient was admitted to the hospital with acute appendicitis. She had idiopathic cervical internal carotid artery vasospasms and had been taking aspirin. We used intracranial oxygen saturation measuring instrument (INVOS®) for anesthetic management during general anesthesia. We administered atropine and continuous small amount of dopamine, and loaded fluids when her blood pressure decreased. We refrained from using medicines which might influence cerebral blood flows. Intracranial oxygen saturation was maintained above baseline during the operation...

Demands associated with the Trendelenburg position (TP) are well known yet there is little attention given to regional cerebral tissue O2 saturation (SctO2) in those undergoing robotic surgery in the TP with CO2 insufflation (C-INSF). This is the first study to report on SctO2 in a wide range of patients undergoing lengthy TP and robotic surgery. We measured SctO2 during robotic surgery in patients in the TP with C-INSF, as well as a control robotic thyroid surgery group who were supine with no C-INSF. We recorded relevant variables and periods of cerebral desaturation (CD)...

INTRODUCTION: The prediction of fluid responsiveness in paediatrics and infants remains problematic. We sought to test the validity of the measurement of StcO2 as a predictive parameter of fluid responsiveness in infants less than one year old during non-cardiac surgery. MATERIALS AND METHODS: This was a prospective observational study on infants aged less than 1 year without any cardiac disease during the intraoperative period of non-cardiac surgery. Cerebral oxygen saturation (StcO2) was obtained using infrared spectroscopic INVOS® monitors...

BACKGROUND: Near-infrared spectroscopy (NIRS) is a noninvasive technique for monitoring tissue oxygenation and perfusion. The aim of this study was to evaluate cerebral and splanchnic NIRS changes in CDH operated infants enrolled into the VICI trial and therefore randomized for ventilatory modalities. MATERIALS AND METHODS: CDH newborns enrolled into the VICI trial (Netherlands Trial Register, NTR 1310) were randomized at birth for high-frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CMV) according to the trial...

BACKGROUND: Non-invasive monitoring of the brain with near-infrared spectroscopy (NIRS) during immediate transition after birth is of growing interest. OBJECTIVE: The aim of this work was to define reference ranges and centile charts for a regional cerebral tissue oxygenation index (cTOI), measured with the NIRO 200NX (NIRO, Hamamatsu, Japan), and cerebral fractional tissue oxygen extraction (cFTOE) during the first 15 min after birth in preterm and term neonates without any medical support...

PURPOSE: Previous studies have found that most cerebral oximeters are subject to inaccuracies secondary to extracranial contamination of the cerebral oximetric signals. We hypothesized that the more advanced second-generation FORE-SIGHT ELITE cerebral oximeter would be significantly less affected by extracranial tissue hypoxemia than the more widely used first-generation INVOS™ 5100C monitor. METHODS: Twenty healthy volunteers aged 18-45 yr had the INVOS and FORE-SIGHT probes placed on their forehead in a random sequence while in the supine position...

INTRODUCTION: In the present study, changes in hemodynamic parameters and cerebral oxygen saturation (rSO2) associated with 10 cm H2O PEEP application were investigated, which is assumed beneficial for the respiratory functions and oxygenation during laparoscopic cholecystectomy (LC) applied at 30° head-up left side position. Data gathered via two devices, namely INVOS and FORESIGHT, were compared. METHODS: After both the ethics committee approval from the hospital and patients' written consents were obtained, patients undergoing elective laparoscopic surgery (only ASA I-II) were randomly divided into two groups (Clinical trials protocol NCT02071550)...
