Comparative Study Clinical Trial Controlled Clinical TrialAspiration of dead space allows isocapnic low tidal volume ventilation in acute lung injury. Relationships to gas exchange and mechanics.
In acute lung injury (ALI) mechanical ventilation damages lungs. We hypothesised that aspiration and replacement of dead space during expiration (ASPIDS) allows normocapnic ventilation at higher end-expiratory pressure (PEEP) and reduced tidal volume (V(T)), peak and plateau pressures (Paw(peak), Paw(plat)), thus avoiding lung damage. ⋯ ASPIDS allowed the use of higher PEEP at lower V(T) and inflation pressure and constant PaCO(2). Multiple Pel/V curves gave insight into the tendency of lungs to collapse.

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.
