Context: The duration of neuromuscular block with rocuronium is affected by old age as well as renal impairment. It would be helpful for anesthetists to know the variation in the block in elderly patients with renal failure and the significance of neuromuscular monitoring in this group.
Aim: The aim of our study is to investigate the neuromuscular effects of 0.6 mg/kg rocuronium under general anesthesia in young adults and elderly patients with or without renal failure.
Study design: Prospective randomized controlled study.
Materials and methods: Young and elderly 100 patients were divided into 4 groups of 25 each, with or without renal failure. General anesthesia with propofol 2 mg kg intravenous (iv), fentanyl 2 µg kg iv, and 60% N2O in O2 were given. Neuromuscular monitoring was started immediately after the induction of anesthesia and before the administration of muscle relaxant. After the stabilization of control responses, 0.6 mg kg rocuronium was injected intravenously. The onset time, time to achieve maximum block, and the recovery times were noted.
Statistical analysis used: The statistical analysis of the data from the study was performed with the Statistical Package for the Social Sciences (SPSS) software for Window Release 14.0. One-way analysis of variance, Bonferroni’s, and chi-square test were used to compare patients’ characteristics.
Results: The duration of block as well as the recovery indices were significantly prolonged in the elderly compared to the young patients. Maximum prolongation was observed in the elderly group with renal failure. This underlines the importance of neuromuscular monitoring in these patients.
