Abstract
Purpose
We compared the reversal doses of sugammadex in surgical cases in which intraoperative neuromuscular monitor were used, to cases in which intraoperative neuromuscular monitoring was not used, retrospectively.
Methods
Data were collected by reviewing the electronic medical records of patients who received rocuronium and sugammadex during general anesthesia at Asahikawa Medical University Hospital between May 1, 2017 and April 30, 2018. The primary outcome was the reversal dose of sugammadex per patient actual body weight (mg/kg) between the group in which intraoperative neuromuscular monitoring was used (NM+ group) and the group in which intraoperative neuromuscular monitoring was not used (NM− group).
Results
A total of 3496 patients were evaluated, with 2544 patients (73%) included in NM+ group and 952 patients (27%) in NM− group. The reversal doses of sugammadex per actual body weight were significantly higher in NM− group compared to NM+ group. In the NM+ group, 521 patients (20%) received < 2 mg/kg sugammadex, 1377 patients (54%) received 2 ~ 2.5 mg/kg sugammadex, and 646 patients (25%) received > 2.5 mg/kg sugammadex. In contrast, 128 patients (13%) received < 2 mg/kg sugammadex, 362 patients (38%) received 2 ~ 2.5 mg/kg sugammadex and 462 patients (49%) received > 2.5 mg/kg sugammadex in NM− group.
Conclusion
This single-center retrospective study demonstrated that the use of intraoperative neuromuscular monitor reduced the reversal dose of sugammadex.
