ABSTRACT
METHODS: Sugammadex vials were fractionated into 25, 50, or 100 mg aliquots, which would be distributed to anesthesia staff by pharmacy staff in approximate 2 mg/kg of actual body weight doses (±10%). We analyzed changes in sugammadex waste and dosing practices 1/1/2019 to 3/15/2023 pre/postintervention (4/1/2021). We gauged dose appropriateness using last train of four (TOF) prior to sugammadex administration.
RESULTS: 7,889 patients 2-17 years (4,771 with documented TOF), ASA 1-4 receiving general anesthesia with a steroidal NMB medication and sugammadex reversal. Pre- and postintervention mean doses were 2.5 mg/kg (SD: 1.2) and 2.4 mg/kg (SD: 0.96), respectively. A smaller proportion of cases received standard 2 or 4 mg/kg doses (pre: 77.6 vs. post: 66.7%). Mean waste per case declined from 4.2 mg/kg (SD: 4.1) to 0.22 mg/kg (SD: 0.38). Among cases with 0 or 1 measured twitches on TOF that should receive at least 4 mg/kg, fewer received at least 3.6 mg/kg (post: 56.7% vs. pre: 66.8%), and a greater proportion received less than 2.2 mg/kg (post: 27.4% vs. pre: 20.7%). Among cases that should have received at least 2 mg/kg by TOF, the proportion of patients receiving more than 3.6 mg/kg declined from 9.5% to 5.2%. Discussion. Fractionating sugammadex vials was associated with decreases in waste, but not dose, and significant underdosing was more likely to occur. While vial fractionation could enable increased access to sugammadex and other costly medications, it may introduce unintended consequences.
