Tramadol combined with local anesthesia for postoperative pain in third molar surgery
摘要
Postoperative pain is a significant challenge in oral surgery. Tramadol exhibits both systemic and local analgesic effects, with proven efficacy in combination with local anesthetics.
PurposeThis study evaluated the efficacy of local anesthetics combined with tramadol in reducing pain and analgesic use after third molar surgery.
Study design, setting, sampleThis randomized, double-blind trial included ASA I–II patients aged 18–50 years and weighing 70–80 kg who were undergoing impacted third molar surgery. Patients requiring extra anesthesia, those with tramadol hypersensitivity, or those who recently used sedatives were excluded.
Independent variablesTwo local anesthetic solutions were compared: the LT group (tramadol and articaine with epinephrine) and the LA group (articaine with epinephrine, control).
Main outcome variablePostoperative pain was measured as the primary outcome via a visual analog scale (VAS) at multiple time points (10 min and 1, 2, 4, 6, 12, 24 and 48 h postsurgery). The secondary outcomes included the timing of the first analgesic intake and the total number of analgesic doses consumed within 48 h.
CovariatesThe covariates included age, sex, BMI, surgical duration, and adverse effects (nausea, vomiting, burning).
AnalysesAge and surgical duration were analyzed with t tests; VAS scores and analgesic use were analyzed with Mann–Whitney U tests; and categorical data were analyzed with Fisher’s exact test or Yates’ correction (p < 0.01).
ResultsSixty patients were randomized into the LT (n = 30) and LA (n = 30) groups. Age, sex, and BMI distributions were similar between the groups. VAS pain scores were lower in the LT group at 1, 2, and 6 h (mean difference: -4.9, -1.9, and − 1.4; p < 0.01) but higher at 4 h (mean difference: 1.5; p < 0.01). The LT group required their first analgesic later (5.2 ± 0.8 vs. 2.0 ± 0.6 h; mean difference: 3.1; p < 0.01) and consumed fewer analgesics (1.8 ± 0.5 vs. 3.6 ± 0.8 doses; mean difference: -1.8; p < 0.01). A transient higher VAS score was observed at 4 h in the LT group, likely reflecting delayed analgesic use. Adverse effects were minimal and not significantly different between groups.
Conclusion and relevanceLocal anesthetics combined with tramadol reduce pain and analgesic use after third molar surgery. This strategy improves recovery and warrants further research for broader applications.
