What it is
A precipitous or fast labor goes from first strong contractions to birth in under three hours. A prolonged labor runs past the usual range. A stalled labor stops moving for hours. Providers may write failure to progress. That is a chart term, not a judgment.
What's typical
Fast labors happen in about 2 to 3 in 100 births, more often with second or later babies. They can mean no time for pain relief and a higher chance of tearing or heavy bleeding. Long labors are more common with first babies. ACOG counts active labor as stalled only after 6 centimeters, with no change for 4 to 6 hours despite strong contractions. Failure to progress is the most common reason for a first cesarean.
What's known
The 2014 ACOG and SMFM guidance gave labor more time on purpose, after large studies showed many normal labors are slower than old charts said. Options for a stall are rest, an epidural so you can sleep, position changes, or medication to strengthen contractions.
What helps
