Tissue Oximetry and Clinical Outcomes.

Alexandros G. SfakianakisστοAnaesthesiologyΠριν από 6 δευτερόλεπτα
A number of different technologies have been developed to measure tissue oxygenation, with the goal of identifying tissue hypoxia and guiding therapy to prevent patient harm. In specific cases, tissue oximetry may provide clear indications of decreases in tissue oxygenation such as that occurring during acute brain ischemia. However, the causation between tissue hemoglobin-oxygen desaturation in one organ (e.g., brain or muscle) and global outcomes such as mortality, intensive care unit length of stay, and remote organ dysfunction remains more speculative. In this review, we describ... περισσότερα »

Effect of Individual Surgeons and Anesthesiologists on Operating Room Time.

Alexandros G. SfakianakisστοAnaesthesiologyΠριν από 6 δευτερόλεπτα
BACKGROUND: Variability in operating room (OR) time causes overutilization and underutilization of the available ORs. There is evidence that for a given type of procedure, the surgeon is the major source of variability in OR time. The primary aim was to quantify the variability between surgeons and anesthesiologists. As illustration, the value of modeling the individual surgeons and anesthesiologist for OR time prediction was estimated. METHODS: OR data containing 16,480 cases were obtained from a general surgery department. The total amount of variability in OR time accounted for b... περισσότερα »

Mechanisms of the Immunological Effects of Volatile Anesthetics: A Review.

Alexandros G. SfakianakisστοAnaesthesiologyΠριν από 6 δευτερόλεπτα
Volatile anesthetics (VAs) have been in clinical use for a very long time. Their mechanism of action is yet to be fully delineated, but multiple ion channels have been reported as targets for VAs (canonical VA targets). It is increasingly recognized that VAs also manifest effects outside the central nervous system, including on immune cells. However, the literature related to how VAs affect the behavior of immune cells is very limited, but it is of interest that some canonical VA targets are reportedly expressed in immune cells. Here, we review the current literature and describe ca... περισσότερα »

The Evolution of TMD Diagnosis: Past, Present, Future

Alexandros G. SfakianakisστοOroFacial Medicine by Alexandros G.SfakianakisΠριν από 7 δευτερόλεπτα
This review explores the principles and process associated with the diagnosis of temporomandibular disorders (TMDs). TMD diagnosis has evolved substantially over the past 25 y. Previously, diagnosis focused solely on aberrations in oral structures, largely without empirical evidence. The Research Diagnostic Criteria for TMD (RDC/TMD) were developed on core principles of 1) a dual-axis system reflecting the biopsychosocial model, 2) a clear operationalization for reliability, and 3) the allowance of multiple diagnoses. These principles were retained in the subsequent validation res... περισσότερα »

The Impact of Surgery and Stored Red Blood Cell Transfusions on Nitric Oxide Homeostasis.

Alexandros G. SfakianakisστοAnaesthesiologyΠριν από 20 δευτερόλεπτα
BACKGROUND: Cell-free hemoglobin (Hb) forms in stored red blood cells (RBCs) as a result of hemolysis. Studies suggest that this cell-free Hb may decrease nitric oxide (NO) bioavailability, potentially leading to endothelial dysfunction, vascular injury, and multiorgan dysfunction after transfusion. We tested the hypothesis that moderate doses of stored RBC transfusions increase cell-free Hb and decrease NO availability in postoperative surgical patients. METHODS: Twenty-six patients undergoing multilevel spine fusion surgery were studied. We compared those who received no stored RB... περισσότερα »

A possible carbon monoxide shuttle in the lung

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 27 δευτερόλεπτα
The Coburn, Forster, Kane Equation (CFKE) describes a current understanding of the physiology of lung uptake and excretion of carbon monoxide (CO). The lung mean capillary PCO is an important term in this equation because it drives CO excretion and functions as "back-pressure" during uptake of exogenous CO. Results of previous studies have indicated that the mean capillary PCO of normal human lungs is equal to values calculated using the Haldane Equation, as described by the CFKE. The physiological explanation of how this parameter is set at this level is unknown. As a possible ex... περισσότερα »

Differential effects of respiratory and electrical stimulation-induced dilator muscle contraction on mechanical properties of the pharynx in the pig.

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 28 δευτερόλεπτα
Introduction: Respiratory stimulation (RS) during sleep often fails to discontinue flow limitation, while electrical stimulation (ES) of the hypoglossus (HG) nerve frequently prevents obstruction. The present work compares the effects of RS and HG-ES on pharyngeal mechanics, as well as the relative contribution of tongue muscles and thoracic forces to pharyngeal patency. Methods: We determined the pressure-area relationship of the collapsible segment of the pharynx in anesthetized pigs under 3 conditions: baseline (BL), RS induced by partial obstruction of the tracheostomy tube, a... περισσότερα »

Cardiovascular control during whole body exercise

Alexandros G. SfakianakisστοPhysiology by Alexandros G.SfakianakisΠριν από 28 δευτερόλεπτα
It has been considered whether during whole body exercise the increase in cardiac output is large enough to support skeletal muscle blood flow. This review addresses four lines of evidence for a flow limitation to skeletal muscles during whole body exercise. First, even though during exercise the blood flow achieved by the arms is lower than that achieved by the legs (~160 vs. ~385 ml/min/100 g) the muscle mass that can be perfused with such flow is limited by the capacity to increase cardiac output (42 l/min, highest recorded value). Secondly, activation of the exercise pressor r... περισσότερα »
