Summary

This trial compares drugs used to reverse muscle relaxants after spine surgery to see which one reduces the risk of having trouble peeing after surgery.

Who is the study for?
Adults aged 18 or older, with a physical status classified as ASA I-III, who are undergoing elective ambulatory spine surgery can join. Excluded are those with allergies to study drugs, neuromuscular disorders, severe kidney/liver disease, recent genitourinary procedures or cancer treatments, BPH symptoms, urinary issues or on related meds.
What is being tested?
The trial is testing if Sugammadex is better than Neostigmine/Glycopyrrolate at preventing urinary retention after spine surgery when reversing the effects of Rocuronium—anesthesia-related muscle relaxation.
What are the potential side effects?
Possible side effects include allergic reactions and heart rhythm changes for both drug options. Sugammadex may cause bleeding issues and mild gastrointestinal symptoms; Neostigmine/Glycopyrrolate might lead to vision problems, dry mouth and difficulty urinating.
