ABSTRACT

The history of tonsillectomy began in the olden days. In India there are reports from Celso, 3000 years ago during the Christian era. The surgical technique of tonsillectomy is still evolving and being modified, based on the introduction of new surgical tools and application of drugs to control main complications: pain and bleeding.
Objective: To compare the control of peritonsillar ropivacaine 2% infiltration versus peritonsillar ropivacaine 2% plus dexamethasone infiltration on pain after tonsillectomy.
Methods: A non-randomized trial was carried out at the Otorhinolaryngology service of the “General Ignacio Zaragoza” Regional Hospital, México (August 2012-July 2013). The surgical dissection was subcapsular and cold handle. The study group received infiltration of 0.2% ropivacaine with dexamethasone and the control group was 0.2% ropivacaine. The postoperative management was with acetaminophen, exclusively. Variables analyzed: pain before intake food and/or analgesics, pain after intake of 100ml of water and presence of ear pain. The pain was registered on the Wong-Baker faces scale (patients ‹ 12 years) and Visual Analog Scale (patients ›12 years). The information was placed in SPSS 10.0 program and statistical analysis was by Chi square.
Results: Pain previously intake analgesics or food and after water intake was slightly lower in the study group. The study group presented a lower level of ear pain (p › 0.05) and did not require additional doses of acetaminophen in the postsurgical period (p ‹ 0.05).
Conclusions: The combination of ropivacaine with dexamethasone provides longer and higher level of analgesia post-tonsillectomy, compared with ropivacaine alone.
