Sugammadex reversal of rocuronium-induced neuromuscular block in Caesarean section patients: A series of seven cases

Abstract

Sugammadex is a selective relaxant-binding agent, which reverses rocuronium-induced neuromuscular blocks of any depth by chemical encapsulation of rocuronium in the plasma in various groups of patients. We reported seven Caesarean section cases, undergoing general anaesthesia with thiopental (6 mg kg-1) and rocuronium (0.6 mg kg-1) who were given desflurane and fentanyl for maintenance of anaesthesia after delivery. The action of rocuronium may be prolonged in pregnant women. At the end of the operation, all patients had a significant degree of neuromuscular block. In five patients, there was no single twitch response and no TOF ratio, one patient had one twitch detectable, and in one patient, a TOF ratio of 3 was detected. The recommended dose of sugammadex for reversal of profound block (4 mg kg -1) or moderate block (2 mg kg-1) was given. In all patients, sugammadex provided rapid and sufficient reversal to TOF >0.9 within 2 min. All patients were monitored after operation, and no signs of recurarization occurred in any patient and no signs of neuromuscular weakness were observed. © 2010 The Author.
