Buccally Absorbed Cannabidiol Shows Significantly Superior Pain Control and Improved Satisfaction Immediately After Arthroscopic Rotator Cuff Repair: A Placebo-Controlled, Double-Blinded, Randomized Trial

この研究はインパクトが大きい可能性があると判断されました。 OEのAIによるハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文の影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することができ、読者は将来の診療を形成する可能性が最も高い論文に焦点を当てることができます。

研究概要

101 patients undergoing an arthroscopic rotator cuff repair were randomized to receive 14 days of buccally absorbed cannabidiol (CBD; n=54; 25mg dose to those ≤80kg, 50mg dose to those >80 kgs) or placebo (n=47) for the control of postoperative pain. The primary outcome of interest was pain intensity measured with a Visual Analog Scale (VAS). Secondary outcomes of interest included patient satisfaction, opioid consumption, nausea, liver enzyme levels, and adverse events. Outcomes were assessed up to 14 days post-operation. Results revealed significantly less pain in the CBD group vs. placebo on Day 1 post-operation only. However, in the subgroup analysis by dose, the superiority in pain scores was only observed in the 50mg group vs. placebo. Patient satisfaction on day 1 and 2 post-operation were also significantly in favour of the CBD group; in the subgroup analysis by dose, this superiority was observed in the 50mg group vs. both the 25mg and placebo groups on day 1, and vs. the placebo group only on day 2. Severity of nausea was significantly greater in the 50mg group vs. the 25mg group.
