Effect and safety of mivacurium chloride and succinylcholine for bronchoscopy: study protocol for a single-center, randomized, non-inferiority, and positive-controlled clinical trial
Year: 2026
Type: article
Study design: Study Protocol
Abstract: BACKGROUND: Succinylcholine is favored for its rapid onset and offset, but its use is limited by adverse effects. Mivacurium chloride, a non-depolarizing relaxant, offers a similar shorter duration and fewer cardiovascular effects, especially without worrying about muscle pain and hyperkalemia, making it a potential alternative in some short-time operations. This study aims to assess the non-inferiority of mivacurium chloride compared to succinylcholine in terms of muscle relaxation effect and safety during flexible bronchoscopy. METHODS: This is a prospective, single-center, randomized, assessor-blinded, positive-controlled trial. Participants scheduled for flexible bronchoscopy requiring muscle relaxation were randomly assigned to receive either mivacurium chloride or succinylcholine. The primary endpoint is the recovery rate of spontaneous breathing within 15 min after discontinuation of muscle relaxants. Other outcomes, including recovery time at different levels, hemodynamic changes, adverse events, and satisfaction from physicians and patients, are also collected. DISCUSSION: This study aims to compare the recovery effect of mivacurium chloride for muscle relaxation during bronchoscopy with succinylcholine, hypothesizing that mivacurium chloride is non-inferior in recovery time and superior in safety and comfort.
