Randomized Controlled Trial Comparative Study
Randomized clinical trial of subcutaneous versus interfascial bupivacaine for pain control after midline laparotomy.
Although patient-controlled analgesia for pain management after abdominal surgery is common, efforts to find alternative effective methods to control postoperative pain are continuing. The aim of this study was to compare postoperative pain levels following intermittent regional administration of bupivacaine via a catheter placed in the rectus sheath or subcutaneously at abdominal surgery through midline incisions. ⋯ IRCT138810142982N1 (http://www.irct.ir).

Randomized Controlled Trial
Late effects of a brief psychological intervention in patients with intermittent claudication in a randomized clinical trial.
The authors previously reported the early results of a trial of a brief psychological intervention to increase physical activity in patients with intermittent claudication. After 4 months, participants in the intervention group walked a mean of 1576 more steps per day than control group participants. The present study followed the original participants to determine whether this behaviour change was maintained over 2 years. ⋯ ISRCTN28051878 (http://www.controlled-trials.com).
