What is uterine hyperstimulation?

Uterine tachysystole: >5 contractions per 10 minutes averaged over 30 minutes. Hyperstimulation + non-reassuring FHR requires reducing or stopping oxytocin, repositioning, IV fluid bolus, and consideration of terbutaline 0.25 mg SQ.

Low-dose vs high-dose oxytocin: which is preferred?

Low-dose (0.5-2 mU/min starting) has lower tachysystole and lower uterine hyperstimulation rate. High-dose (4-6 mU/min) achieves active labor faster. Neither shows clearly superior cesarean rate. Low-dose preferred in VBAC candidates.

What is the maximum oxytocin dose?

No absolute maximum, but doses >40-60 mU/min rarely add benefit and increase risk. Most clinical protocols cap at 20-40 mU/min. Dose-response plateau occurs for uterine contraction frequency around 20-36 mU/min.
