“…If hemoglobin and hematocrit parameters at 26 to 28 weeks of gestation are within normal ranges, measurement of these variables can be avoided during hospital stay for delivery care. (21) This study showed that at the postpartum return visit, hemoglobin and hematocrit indices increased in relation to hospital discharge values without reaching the mean values seen at admission. The indices at the postpartum return visit were significantly higher in women undergoing spontaneous delivery without episiotomy than at delivery with episiotomy.…”

Objective: To analyze hemorrhage at vaginal delivery using hemoglobin and hematocrit indices. Methods: This was a cross-sectional study of 328 vaginal deliveries divided into spontaneous delivery with or without episiotomy and forceps delivery. The sample was randomly stratified by type of vaginal delivery. Data were collected at admission for delivery, hospital discharge and postpartum return visit. Results: There were 122 (37.2%) deliveries without episiotomy, 147 (44.8%) with episiotomy, and 59 (18.0%) with forceps delivery and episiotomy. Hemoglobin values between admission for delivery and discharge ranged from -5.9 g/dl to 0.7 g/dl. Hemoglobin reduction was significantly higher in women having forceps delivery than in those with spontaneous deliveries, with and without episiotomy (p=0.0133 and p<0.0001, respectively). Hemorrhage was greater in the forceps delivery group than in the other groups. Conclusion: The analysis of hemorrhage at vaginal delivery by using hemoglobin and hematocrit indices showed variation among the three types of vaginal delivery studied. There was greater hemorrhage with forceps delivery and less hemorrhage with spontaneous delivery. In women with forceps delivery, postpartum indices were lower than those at hospital admission. ResumoObjetivo: Analisar a hemorragia no parto vaginal através dos índices de eritrócitos e hematócrito. Métodos: Estudo transversal realizado em 328 partos vaginais divididos em: espontâneo, com e sem episiotomia, e parto fórceps. A amostragem foi aleatória estratificada por tipo de parto vaginal. Os dados foram coletados na internação para o parto, na alta hospitalar e no retorno puerperal. Resultados: Foram estudados 122 (37,2%) partos sem episiotomia, 147 (44,8%) com episiotomia e 59 (18,0%) com uso de fórceps e episiotomia. O valor individual de hemoglobina, entre a internação para o parto e a alta hospitalar variou de -5,9 g/dl a 0,7 g/dl.A redução da hemoglobina foi significativamente maior no parto fórceps comparado aos partos espontâneos, com e sem episiotomia, p=0,0133 e p<0,0001, respectivamente. No parto fórceps a hemorragia é maior quando comparada aos outros tipos de parto Conclusão: A análise da hemorragia no parto vaginal através dos índices de eritrócitos e hematócrito evidenciou que há variação nos três tipos de parto vaginal estudados, sendo a hemorragia maior no parto fórceps e menor no parto vaginal espontâneo. No puerpério, nos casos de partos fórceps estes índices mantiveram-se inferiores aos da internação.
