Scientific title
PATCH Trial: Post-tonsillectomy Analgesia with buprenorphine Transdermal patCH: a prospective, randomised, phase IV, open label clinical trial to study the therapeutic use of buprenorphine 20 mg (Transtec®) matrix transdermal patch in the management of post-tonsillectomy pain in adults
Acronym
PATCH Trial
Study hypothesis
To establish whether post-tonsillectomy analgesia using a transdermal patch has benefits over currently used oral analgesia, by comparatively measuring the clinical efficacy, the effective and perceived pain control, and the rate at which complications and adverse effects occur.
