The long-term use of opioid analgesic drugs to treat chronic non-cancer pain (CNCP) is a major component of pain pharmacotherapy. The interpretation of the evidence concerning its efficacy and risks is currently debated. ⋯ To minimize the risks of opioid analgesic treatment, physicians must be aware of its contraindications and must regularly reassess its efficacy and side effects. Pharmacotherapy should be combined with other types of treatment.

Mechanical ventilation is a common and often life-saving intervention in intensive care medicine. About 35% of all patients in intensive care are mechanically ventilated; about 15% of these patients develop a ventilation-associated pneumonia. The goal of ventilation therapy is to lessen the work of respiration and pulmonary gas exchange and thereby maintain or restore an adequate oxygen supply to the body's tissues. Mechanical ventilation can be carried out in many different modes; the avoidance of ventilation-induced lung damage through protective ventilation strategies is currently a major focus of clinical interest. ⋯ The currently available scientific evidence with respect to clinically relevant endpoints is inadequate for all of these newer modes of ventilation. It appears, however, that they can lower both the invasiveness and the duration of mechanical ventilation, and thus improve the care of patients who need ventilation. Randomized trials with clinically relevant endpoints must be carried out before any final judgments can be made.
