摘      要：OBJECTIVE:To compare maternal preoperative and postoperative hemoglobin variation after cord clamping. METHODS: Randomized clinical trial performed in Porto Alegre, RS from January to December 2012. It was included 356 women with habitual risk gestations. In the immediate cord clamping group, the umbilical cord section was realized between 0 and 60 s (group 1) while in the delayed cord clamping group it was realized 60 s (group 2). RESULTS: The mean (±standard deviation [SD]) preoperative hemoglobin was 12.13 ± 1.06 in the group 1 and 12.13 ± 1.11 in the group 2. The mean (±SD) postoperative day 2 hemoglobin level was 10.19 ± 1.46 in the group 1 and 10.24 ± 1.42 in the group 2. CONCLUSIONS: Delayed umbilical cord clamping resulted in a similar maternal hemoglobin level reduction at postoperative day 2.
