First group was admitted in latent phase of labor (250 samples) and second group in active phase (250 samples). Data was collected with observation of labor process, interview with mothers and study of patient’s records. Collecting data tool was a questionnaire included samples characteristics and evaluation of maternal outcomes during 1, 2, 3 and 4th stages of labor, before discharge and 10 days after delivery. Data were analyzed using SPSS software version 13, t-test, chi-square and regression logistic tests. P<0.05 was considered as the significant level. P value less than 0.05 was considered significant.
Results: Rate of oxytocin use for induction and augmentation of labor, amniotomy and prescription of Ampicillin, Hyoscine, Pethidine and Promethazine had significant differences between two groups (p<0.05). In study of maternal outcomes during the second, third and fourth stage of labor, use of uterus compression during delivery, complications of fourth stage of labor and abdominal massage of uterus had significant differences between two groups (p<0.05). Study of maternal outcomes before discharge and 10 days after delivery showed that there were significant differences between two groups in terms of post partum hemorrhage (p=0.017), hemoglobin (p=0.007) and hematocrit (p=0.008) and duration of stay in postpartum ward (p=0.04).
Conclusion: Admitted in latent phase increase maternal complications, causes maternal invasive interventions and increases time of hospitalization. Therefore, it is recommended that physicians and midwives do not admit mothers in latent phase if there is no indication of admission.
