Operating room (OR) is a cost-intensive environment, and it should be managed efficiently. When improving efficiency, shortening case duration by parallel processing, training of the resident surgeons, the choice of anesthetic methods, effective scheduling, and monitoring of the overall OR performance are important. ⋯ Pre-operative clinic and functionally designed facilities support efficiency. OR personnel must be kept motivated by clear management and leadership, supported by superiors.

Comparative StudyEffects of halothane, isoflurane, and sevoflurane on lipid peroxidation following experimental closed head trauma in rats.
In a rat closed head trauma model we examined both the time course of lipid peroxidation and the effects of halothane, isoflurane, and sevoflurane on it by analysis of malondialdehyde (MDA) formation. ⋯ MDA levels with the isoflurane group were lower than in the other trauma groups, which suggest that isoflurane, given after closed head trauma, might be protective against lipid peroxidation of cerebral injury.

Maximal hysteresis: a new method to set positive end-expiratory pressure in acute lung injury?
No methods are superior when setting positive end-expiratory pressure (PEEP) in acute lung injury (ALI). In ALI, the vertical distance (hysteresis) between the inspiratory and expiratory limbs of a static pressure-volume (PV) loop mainly indicates lung recruitment. We hypothesized that PEEP set at the pressure where hysteresis is 90% of its maximum (90%MH) would give similar oxygenation, but less cardiovascular depression than PEEP set at the pressure at lower inflection point (LIP) on the inspiratory limb or at the point of maximal curvature (PMC) on the expiratory limb in ALI. ⋯ In this porcine lung injury model, PEEP set at 90% MH gave better lung mechanics and hemodynamics, than PEEP set at PMC or LIP.
