Stop awarness ..



Awarness occurance  reported to range from 0.2–1.0%, and is   probably underestimated..

Here are  the tips to avoid this complication....They are 12...
Consider amnestic premedication (midazolam, scopolamine)

Routine equipment checks: e.g., correct placement of vaporizer).

End-tidal monitoring of volatile anesthetics with low-concentration alarm).

Adequate dosing of induction agents.

Use of appropriate volatile anesthetic con- sertion centration or propofol dose for maintenance.

Realize potential for awareness with hypotension/ hypovolemia

Judicious use of neuromuscular blocking agents combined with careful monitoring.

Frequent checks of intravenous lines and pumps when using total intravenous anesthesia.

Clear labeling of all syringes.

Quiet, professional operating room atmosphere: minimize auditory input.

Consider use of anesthetic depth monitor (Bispectral Index).

Calm reassurance when strong possibility of awareness suspected.

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)...

The pressure volume loop...

In the pressure-volume loop below, cardiac work is best represented by:   the area of the curve  the slope of the line from points C to D  the distance of the line from points C to D  the slope of a line from points A to D .. .. ... .... ... .... .... .... In the pressure-volume loop below, cardiac work is best represented by:  the area of the curve Cardiac work is the product of pressure and volume and is linearly related to myocardial oxygen consumption. Cardiac work is best represented by the area of the curve of a pressure-volume loop.

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
