Do intercontraction intervals predict when a woman at term should seek evaluation of labor?
Labor assessment program reduced time in the labor ward
Labor assessment programs attempt to delay admission during early active labor. One randomized clinical trial (N=209) among low-risk women with reassuring maternal and fetal assessments in early labor divided the women into 2 groups when they presented for labor and delivery. One group received advice, encouragement, and support along with instructions to walk or return home and come back when labor became more active (defined as regular, painful contractions and dilation of at least 3 cm). The other group was admitted directly to the labor and delivery ward. The study found that early labor assessment decreased use of analgesics and oxytocin and reduced time spent in the labor ward.6
Recommendations
The American College of Obstetricians and Gynecologists (ACOG) acknowledges in patient education literature that distinguishing true from false labor is difficult. ACOG lists characteristics of each and recommend that a woman monitor the frequency of contractions for an hour and call the doctor’s office or hospital if she thinks she’s in labor.7
Similarly, a patient handout from the American College of Nurse-Midwives recommends calling the health care provider if contractions are ≤5 minutes apart for more than 1 hour, several contractions are so painful that the woman cannot walk or talk, or her water breaks.8
A standard textbook describes normal uterine contractions during active labor as occurring every 2 to 5 minutes, and as often as every 2 to 3 minutes.9
