ABSTRACT
BACKGROUND: After reversal of a rocuronium-induced neuromuscular blockade with sugammadex, the recovery of train-of-four ratio to 0.9 is faster than recovery of first twitch of the train-of-four to 90% in adults. These findings after reversal of neuromuscular blockade with sugammadex have not yet been investigated in pediatric patients. AIMS: The aim of this retrospective analysis was to investigate the relationship of the recovery of first twitch of the train-of-four height and train-of-four ratio after reversal of rocuronium-induced neuromuscular blockade with sugammadex in pediatric patients. METHODS: Patients ASA I-III, aged 2-11 years, and who underwent abdominal and/or perineal surgery were included in the analysis. After extracting the necessary data from the hospital database, the patients were divided into 2 groups based on the dose of sugammadex received: group A: 2 mg.kg-1 for reversal of moderate neuromuscular blockade and group B: 4 mg.kg-1 for reversal of deep neuromuscular blockade. The relationship of the recovery of first twitch of the train-of-four height and train-of-four ratio in these 2 groups were analyzed. RESULTS: Data from 43 pediatric patients aged 2-11 years could be analyzed. The first twitch of the train-of-four height at the recovery of train-of-four ratio to 0.9 in group B was statistically significantly lower compared with group A. This height 3 and 5 minutes after the train-of-four ratio reached 0.9 showed no statistically significant differences between groups. CONCLUSION: The results were in line with the results found in adults and showed that the train-of-four ratio recovered to 0.9 was faster than first twitch of the train-of-four height recovered to the same level.
