Tidal Volumes during General Anesthesia

Intraoperative ventilation: incidence and risk factors for receiving large tidal volumes during general anesthesia

BACKGROUND There is a growing concern of the potential injurious role of ventilatory over-distention in patients without lung injury. No formal guidelines exist for intraoperative ventilation settings, but the use of tidal volumes (VT) under 10 mL/kg predicted body weight (PBW) has been recommended in healthy patients. We explored the incidence and risk factors for receiving large tidal volumes...

Monitoring end-tidal ethanol concentrations during general anesthesia.

AS many as 40% of patients who present with traumatic brain injury have positive blood–alcohol test results. Small, portable devices designed to measure ethanol concentrations in exhaled breath have been used extensively by law enforcement officials to estimate blood– alcohol measurements accurately in drunk drivers. In the case of patients who have an altered mental status or who do not emerge...

Small tidal volumes, positive end-expiratory pressure, and lung recruitment maneuvers during anesthesia: good or bad?

Anesthesiology, V 123 • No 3 501 September 2015 M ECHANICAL ventilation may cause harm to the lung, at least if the lung is already hurt as is the case in intensive care. Can it be harmful also when ventilating the “lung-healthy” patient during anesthesia? Probably not during anesthesia alone, as suggested by animal experiments on prolonged mechanical ventilation,1,2 but inflammatory events,3 s...
