Delivery time with drainage and no drainage of umbilical cord blood in anemic and nonanemic patients in the hospital Vicente Corral Moscoso, Cuenca - Ecuador 2007

OBJECTIVE: To compare the time of the third period of the childbirth of subject the anemic and non anemic patients to the procedure of drainage of blood of the umbilical cord versus pinzamiento of the cord, in atmospheres of the Obstetrical Center of the Hospital Vicente Corral Moscoso. PATIENTS AND METHODS: With an experimental design a clinical study was made, controlled, randomized the sample included 200 patients, the experimental group included/understood 100 patients in whom the umbilical cord blood was drained 50 anemic and 50 non anemic ones, and the control group with pinzamiento of the cord integrated 100 patients, 50 anemic and 50 non anemic ones. RESULTS: When comparing the duration of the third period of the childbirth of the group with drainage obtained an average of 4.6 ± 1.4 min and in the group with pinzamiento 9.07 ± 2.5 min. The difference was significant (P = 0.0001). When the duration of the third period of the childbirth from 1 to 5 was compared min versus 6 to 10 min, most of the patients of the group with drainage, min was between 1 to 5, with a RR 0,239 (IC 95: 0,188 - 0,358), RRA 70,1%, RRR 76,1%, NT 1,426, in the anemic ones, and a RR 0,250 (IC 95: 0.179 - 0,383), RRA 66,1%, RRR 75%, NT 1,513 in the non anemic ones. The volume of drainage in the training group, had an average of 60.3 ± 19,5 mililiter in anemic and the 56,9 ± 18 mililiter in the non anemic ones (P = 0,369). The hemorrhage of the third period of the childbirth of the group with drainage had an average of 197.6 mililiter ± 36 SD versus the group with pinzamiento 277,4 mililiter ± 49 SD with a value p 0.0001 which is statistically significant in favor of the drainage. When the hemorrhage of the third period of the childbirth was compared of < 250 mililiter versus 250 to 500 mililiter most of the patients of the group with drainage, was in < 250 mililiter, with a RR 0,070 (IC 95: 0.025 - 0,168), RRA 80%, RRR 93%, NT 1,25, in the anemic ones, and a RR 0,074 (IC 95: 0.020 - 0,246), RRA 50%, RRR 92,6%, NT 2 in the non anemic ones. CONCLUSIONS: The maneuver of the drainage of blood of the umbilical cord reduces to the time and the hemorrhage of the third period of the childbirth in patients with slight anemia and non anemic without producing adverse effects.
