Effect of Sarcopenia and Frailty on Rocuronium Pharmacodynamics in Geriatric Patients
2026年7月27日 更新者：Betul Kozanhan、Konya Meram State Hospital
This prospective observational study aims to evaluate whether sarcopenia and frailty affect the pharmacodynamic profile of rocuronium in geriatric patients undergoing elective surgery under general anesthesia.

研究人群
The study population will consist of geriatric patients aged 65 years or older who are scheduled for elective surgery under general anesthesia with endotracheal intubation and rocuronium-induced neuromuscular blockade.
Before surgery, patients will be evaluated for frailty and sarcopenia using predefined clinical and ultrasonographic criteria.
According to these assessments, patients will be classified into four cohorts: frailty only, sarcopenia only, both frailty and sarcopenia, and neither frailty nor sarcopenia.
描述
Inclusion Criteria:
- Scheduled to undergo elective surgery under general anesthesia requiring endotracheal intubation
- Planned use of rocuronium for neuromuscular blockade
- Quantitative neuromuscular monitoring planned during anesthesia
- American Society of Anesthesiologists physical status I-III
- Ability to provide written informed consent
- Completion of preoperative frailty and sarcopenia assessment
Exclusion Criteria:
- Emergency surgery
- Known neuromuscular disease
- History of allergy or contraindication to rocuronium, sugammadex
- Severe hepatic insufficiency
- Severe renal insufficiency
- Use of drugs known to significantly affect neuromuscular transmission
- Preoperative mechanical ventilation or intensive care unit admission
- Inability to perform a frailty or sarcopenia assessment
- Patients in whom quantitative neuromuscular monitoring cannot be properly performed
- Refusal to participate in the study
