Randomized Controlled Trial Clinical TrialSmoking cessation through comprehensive critical care.
There has been little research on smoking cessation after critical illness. Smokers make up a high percentage of patients admitted to intensive care (ICU) and stopping smoking is one message that should be clearly given to recovering patients. The recovery period provides an important opportunity for patients to quit smoking as the period of sedation and ventilation allows patients to start nicotine withdrawal. ⋯ Twenty out of thirty-one intervention patients and 16/30 control patients were smokers pre-ICU admission. At the 6-month follow-up, previous smokers given the rehabilitation package had a relative risk reduction for smoking of 89% (CI 98%-36%). Smoking cessation after critical illness is aided by the provision of a rehabilitation programme.

Comparative StudyAssessment of PEEP-induced reopening of collapsed lung regions in acute lung injury: are one or three CT sections representative of the entire lung?
To study whether PEEP-induced reopening of collapsed lung regions--defined as the decrease in nonaerated lung volume measured on a single or three computerized tomographic (CT) sections--is representative of the decrease in overall nonaerated lung volume. ⋯ PEEP-induced reopening of collapsed lung regions measured on a single or three CT sections sensibly differs from the reopening of collapsed lung regions measured on the overall lung. The inhomogeneous distribution of PEEP-induced reopening of collapsed lung regions along the cephalocaudal axis probably explains these discrepancies.

Comparative StudyResults of respiratory mechanics analysis in the critically ill depend on the method employed.
To compare the measurements of total resistance and dynamic elastance determined by different techniques of respiratory mechanics analysis based on the time or frequency domains. ⋯ The wide agreement limits show that respiratory mechanics analysis is very dependent on the measurement technique used, particularly for resistance, perhaps due to the higher dependence on frequency.
