Analgesic effect of paracetamol combined with low-dose morphine versus morphine alone on patients with biliary colic: a double blind randomized controlled trial

摘要

BACKGROUND:Numerous drugs have been proposed to alleviate pain in patients with biliary colic, especially opioids, but still there is a tendency to use less narcotics because of their side effects and the unwillingness of some patients. The present study aimed to compare the analgesic effect of paracetamol combined with low-dose morphine versus morphine alone in patients with biliary colic.
