Fetal Compromise ....



Excluding premature infants, up to 23% of cases of cerebral palsy are related to intrapartum asphyxia .

The consequences of unrecognized or poorly managed emergencies can be devastating.

 A well-coordinated team that consists of an anesthesiologist, obstetrician, neonatologist/pediatrician, and nurses is one of the most important elements in the care of a compromised fetus.

There must be uniform agreement on the terms used to describe the fetus at risk.

The American College of Obstetrician and Gynecologists (ACOG) has suggested that the term “fetal distress” be replaced with the term “nonreassuring fetal status,” which describes the clinician's interpretation Clinicians rely on indirect parameters such as fetal heart rate, fetal acid-base status, and, more recently, fetal pulse oximetry.

All of these parameters are subject to interpretation. Nonreassuring status describes compromised fetal gas exchange (asphyxia) and, at the extreme, there can be a complete cessation of fetal gas exchange (ie, fetal anoxia). Complete cord occlusion, sustained bradycardia, uterine rupture, and ongoing tetanic uterine contractions are examples of complete cessation of gas exchange (anoxia).

 Fetal anoxia can be lethal in less than 10 minutes . All hospitals need a well-planned emergency protocol to distinguish the different kinds of “unplanned” or “emergency” cesarean sections to help delineate an optimal time frame for delivery.

Driving Pressure in ARDS: A new concept!

Driving Pressure and Survival in the Acute Respiratory Distress Syndrome Marcelo B.P. Amato, M.D., Maureen O. Meade, M.D., Arthur S. Slutsky, M.D., Laurent Brochard, M.D., Eduardo L.V. Costa, M.D., David A. Schoenfeld, Ph.D., Thomas E. Stewart, M.D., Matthias Briel, M.D., Daniel Talmor, M.D., M.P.H., Alain Mercat, M.D., Jean-Christophe M. Richard, M.D., Carlos R.R. Carvalho, M.D., and Roy G. Brower, M.D. N Engl J Med 2015; 372:747-755 February 19, 2015 DOI: 10.1056/NEJMsa1410639 BACKGROUND Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (V T ), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress syndrome (ARDS), but the relative importance of each of these components is uncertain. Because respiratory-system compliance (C RS ) is strongly related to the volume of aerated remaining functional lung during disease (termed functional lung size)...

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body
