Abstract (English)  :

The effect of delivering in a birth chair on duration of second stage labor, perineal swelling, incidence of episiotomies, lacerations, hemorrhoids, and maternal blood loss was examined in a prospective quasi-experimental study. The sample consisted of 55 primiparous women, 37 to 41 weeks gestation, with normal pregnancy and labor; 22 delivered on a traditional delivery table (DT) and 33 in a birth chair (BC). Comparisons were made between groups for mean duration of second stage labor, mean time bearing down in the delivery room, mean maternal blood loss, frequency of instrument-assisted deliveries, frequency of episiotomies and lacerations, and frequency of perineal swelling and hemorrhoids. The two groups were statistically similar for weight of infant. No significant difference was found between groups for mean duration of second stage labor (BC M = 55 minutes, DT M = 43 minutes) or mean time bearing down (BC M = 60 minutes, DT M = 53 minutes). No difference was found in the amount of blood loss between the two groups as measured by the mean difference in the pre- and postdelivery hemoglobin (BC M change = 1.4 Gms, DT M change = 1.8 Gms). The lack of significant differences in blood loss may be due to the fact that the angle of the birth chair was lowered during or after delivery in 88% of the cases. The incidence of instrument-assisted deliveries (BC = 7, DT = 6), episiotomies (BC = 27, DT = 20), lacerations (BC = 17, DT = 5), and hemorrhoids (BC = 14, DT = 4) was similar between groups.(ABSTRACT TRUNCATED AT 250 WORDS)
