INTRODUCTION: Shock, defined as a state of tissue hypoperfusion and the tissues reperfusion, is the main goal of management of shock. Increase in central venous saturation (CvSo2) and decrease in blood lactate level are useful in assessment of adequacy of tissue perfusion. Near-infrared spectroscopy is a noninvasive way to observe real-time changes in regional cerebral saturation and has been used in patients with different brain diseases. There is a small body of literature suggesting that cerebral regional oxygen saturation (CrSo2) monitoring added a value in assessment and management of intensive care unit (ICU) patients...

REVIEW
John C Greenwood, Clinton J Orloski
Resuscitation goals for the patient with sepsis and septic shock are to return the patient to a physiologic state that promotes adequate end-organ perfusion along with matching metabolic supply and demand. Ideal resuscitation end points should assess the adequacy of tissue oxygen delivery and oxygen consumption, and be quantifiable and reproducible. Despite years of research, a single resuscitation end point to assess adequacy of resuscitation has yet to be found. Thus, the clinician must rely on multiple end points to assess the patient's overall response to therapy...

REVIEW
Jared Radbel, Daniel Boutsikaris
Recent literature continues to refine which components of the early goal-directed therapy (EGDT) algorithm are necessary. Given it utilizes central venous pressure, continuous central venous oxygen saturation, routine blood transfusions, and inotropic medications, this algorithm can be timely, invasive, costly, and potentially harmful. New trials highlight early recognition, early fluid resuscitation, appropriate antibiotic treatment, source control, and the application of a multidisciplinary evidence-based approach as essential components of current sepsis management...

BACKGROUND: Neurally Adjusted Ventilatory Assist (NAVA) is a mode of assisted mechanical ventilation that delivers inspiratory pressure proportionally to the electrical activity of the diaphragm. To date, no pediatric study has focused on the effects of NAVA on hemodynamic parameters. This physiologic study with a randomized cross-over design compared hemodynamic parameters when NAVA or conventional ventilation (CV) was applied. METHODS: After a baseline period, infants received NAVA and CV in a randomized order during two consecutive 30-min periods...

Right atrial isomerism and pulmonary atresia combined with major aortopulmonary collateral arteries are very rare. Surgical treatment becomes more challenging when an extracardiac total anomalous pulmonary venous connection (TAPVC) requiring surgical repair neonatally is also present. We describe a successful staged Fontan operation for a neonate with a single ventricle, right atrial isomerism, pulmonary atresia with major aortopulmonary collateral arteries, a small central pulmonary artery and a supracardiac TAPVC...

The retinal oximeter is a new tool for non-invasive measurement of retinal oxygen saturation in humans. Several studies have investigated the associations between retinal oxygen saturation and retinal diseases. In the present systematic review, we examine whether there are associations between retinal oxygen saturation and retinal ischaemic diseases. We used PubMed and Embase to search for retinal oxygen saturation and retinal ischaemic diseases. Three separate searches identified a total of 79 publications...

BACKGROUND: Intradialytic hypotension (IDH) has a dramatic impact on the main outcomes of dialysis patients. Early warning of hemodynamic worsening during dialysis would enable preventive measures to be taken. Blood oxygen saturation (SO2) is used for hemodynamic monitoring in the critical care setting and may provide useful information about IDH onset. AIM: To evaluate whether short- and medium-term variations in the SO2 signal (ST-SO2var, MT-SO2var,) during dialysis are a predictor of IDH...

OBJECTIVE: The current practice in treatment of severe sepsis and septic shock is to ensure adequate oxygenation and perfusion in patients, along with prompt administration of antibiotics, within 6 hours from diagnosis, which is considered the "golden hour" for the patients. One of the goals of treatment is to restore normal tissue perfusion. With this goal in mind, some parameters have been used to determine the success of treatment and mortality rate; however, none has been proven to be the best predictor of mortality rate in sepsis patients...

PURPOSE: Steep Trendelenburg position and pneumoperitoneum during robotic-assisted laparoscopic prostatectomy (RALP) increase intracranial pressure (ICP) and may alter cerebral blood flow (CBF) and oxygenation. Volatile anesthetics and propofol have different effects on ICP, CBF, and cerebral metabolic rate and may have different impact on cerebral oxygenation during RALP. In this study, we measured jugular venous bulb oxygenation (SjO2) and regional oxygen saturation (SctO2) in patients undergoing RALP to evaluate cerebral oxygenation and compared the effects of sevoflurane and propofol...

BACKGROUND: This study aimed to evaluate Fontan circulation which was observed over 30 years. METHODS: Forty patients who underwent a Fontan operation between 1974 and 1986 and survived (group S, n = 20) or died in the late period (group LD, n = 20) were evaluated. The median age at operation was 10 years (range 2-32 years). The diagnoses were tricuspid atresia in 21, single ventricle in 9, and others in 10. The Fontan procedure was a right atrium-pulmonary artery graft in 2, atriopulmonary connection in 28, and right atrium-right ventricle anastomosis in 10 (Björk in 4, graft in 6)...

BACKGROUND: Literature suggests poorer outcomes during anaemia as well as following red blood cell transfusion (BT) in brain injured patients. Recently, central venous oxygen saturation (ScvO2 ) has been proposed as a physiological trigger to guide red BT. In this study, we looked at ScvO2 changes following BT in patients admitted to a neurointensive care unit (NICU). STUDY DESIGN: In this prospective, observational study, adult, acutely ill neurological patients of >18 years were recruited...
