Abstract：
OBJECTIVE: To report on postoperative outcomes related to the administration of neostigmine for reversal of nondepolarizing neuromuscular blocking agents in cardiovascular surgery patients, with a specific focus on the duration of postoperative mechanical ventilation as the primary endpoint.
METHODS: A retrospective cohort study design was followed to achieve the study objectives.
METHODS: This was a single-center, chart review study conducted at a large academic medical center of adult patients post-cardiovascular surgery.
METHODS: Patients were included if they had received a bolus dose of perioperative nondepolarizing neuromuscular blocking agent and underwent one of the targeted cardiovascular surgeries.
METHODS: Final analysis comprised of 175 patients, 95 of whom received neostigmine and 80 who did not receive neostigmine.
RESULTS: The primary endpoint was the duration of postoperative mechanical ventilation. When controlling for all covariates, neostigmine use was associated with a 0.34-hour reduction (∼20.4 min) in duration of mechanical ventilation (parameter estimate: 0.66, 95% confidence interval 0.49-0.89; p = 0.0071). More patients who received neostigmine met the early extubation benchmark of less than 6 hours (55 v 34 patients; p = 0.04). Finally, neostigmine use was not found to be associated with increased risk of respiratory complications or postoperative nausea and/or vomiting.
CONCLUSIONS: The use of neostigmine was found to have a protective effect on the duration of postoperative mechanical ventilation without increasing the risk of adverse complications.
