NCT06962007
Study Objective: This study aims to evaluate the incidence, severity, and risk factors of sugammadex-induced mouth clenching during neuromuscular blockade (NMB) reversal in adult surgical patients. Study Design: This prospective, randomized, double-blind, controlled clinical trial enrolls adult patients (ASA physical status I-II, aged 19-70 years) undergoing elective surgery under general anesthesia with rocuronium. Patients will be randomized into four groups to receive either sugammadex at doses of 1 mg/kg, 2 mg/kg, or 4 mg/kg, or a combination of pyridostigmine and glycopyrrolate. Primary Outcome: The primary outcome is the incidence of clenching within 10 minutes after NMB reversal, assessed by clinical observation, masseter EMG, and airway pressure changes, using a novel five-grade severity scale. Secondary Outcomes: Secondary outcomes include the severity of clenching, time to TOF ratio ≥0.9, BIS values at clenching onset, complications, and identification of risk factors such as dose, sex, BIS, age, BMI, and rocuronium dose. Significance: This study seeks to improve perioperative safety by identifying modifiable risk factors and informing dose adjustments or alternative reversal strategies to prevent sugammadex-induced clenching, particularly in high-risk populations.
NCT07072663
Cerebral venous disorders, including cerebral venous sinus stenosis (CVSS) and cerebral venous sinus thrombosis (CVST), can obstruct venous blood drainage, leading to intracranial hypertension. However, their effects on glymphatic function and white matter integrity in the brain remain poorly understood. Therefore, this study will enroll healthy controls, CVSS patients, and CVST patients to compare differences in glymphatic function and white matter microstructural integrity. Additionally, CVSS and CVST patients will undergo a 3-month follow-up to investigate the interrelationships and longitudinal changes among clinical parameters, glymphatic function, and white matter integrity.
