Pain assessment is associated with decreased duration of mechanical ventilation in the intensive care unit: a post Hoc analysis of the DOLOREA study.
Critically ill patients frequently experience pain, but assessment rates remain below 40% in mechanically ventilated patients. Whether pain assessment affects patient outcomes is largely unknown. ⋯ Pain assessment in mechanically ventilated patients is independently associated with a reduction in the duration of ventilator support and of duration of ICU stay. This might be related to higher concomitant rates of sedation assessments and a restricted use of hypnotic drugs when pain is assessed.

To date, no study has evaluated the impact of specific healthcare provider and parent behaviors on children's distress and coping during anesthesia induction. ⋯ The data presented here provide evidence for a relation between adult behaviors and children's distress and coping at anesthesia induction. These behaviors are trainable, and hence it is possible to test whether modifying physician behavior can influence child behavior in future studies.

Acute hypercapnic acidosis protects against lung injury caused by nonseptic insults and after both pulmonary and systemic sepsis. The authors wished to dissect the contribution of the acidosis versus hypercapnia per se to the effects of hypercapnic acidosis on the hemodynamic profile and severity of lung injury induced by systemic sepsis. ⋯ Both hypercapnic acidosis and buffered hypercapnia attenuate the hemodynamic consequences of systemic sepsis. In contrast, hypercapnic acidosis, but not buffered hypercapnia, reduced the severity of sepsis-induced lung injury.

Intraoperative hypotension (IOH) is frequently associated with adverse outcome such as 1-yr mortality. However, there is no consensus on the correct definition of IOH. The authors studied a number of different definitions of IOH, based on blood pressure thresholds and minimal episode durations, and their association with 1-yr mortality after noncardiac surgery. ⋯ This observational study showed no causal relation between IOH and 1-yr mortality after noncardiac surgery for any of the definitions of IOH. Nevertheless, additional analysis suggested that for elderly patients, the mortality risk increases when the duration of IOH becomes long enough. The length of this duration depends on the designated blood pressure threshold, suggesting that lower blood pressures are tolerated for shorter durations. The effect of IOH on 1-yr mortality remains debatable, and no firm conclusions on the lowest acceptable intraoperative blood pressures can be drawn from this study.
