Randomized Controlled Trial Clinical Trial
Sedation versus general anaesthesia in paediatric patients undergoing chest CT.
CT of the chest in paediatric patients often requires sedation or general anaesthesia to minimize motion artefacts. Both sedation and general anaesthesia are associated with atelectasis which obscures the underlying pulmonary pathology. We conducted a prospective study to compare these two methods with respect to degree of motion artefacts and extent of atelectasis. ⋯ Whenever the clinical condition permits it, sedation rather than general anaesthesia should be given to paediatric patients undergoing chest CT.

Randomized Controlled Trial Comparative Study Clinical Trial
Ultrasonographic findings after conservative treatment of acute appendicitis and open appendicectomy.
In a randomized study we investigated the effects of antibiotics as the only treatment in acute appendicitis. Forty patients were examined, 19 after antibiotic treatment (one operated due to perforation) and 21 after surgery. All patients were examined prior to randomization, after 10 days and after 30 days. ⋯ In 5 of the 8 patients the appendix was still visualized after 1 month. Three of these 5 had recurrent appendicitis within a year. It is concluded that US can be used not only in diagnosing acute appendicitis, but also in the evaluation of treatments such as antibiotics.
