Comparative StudyScalp blood lactate for intra-partum assessment of fetal metabolic acidosis.
To study to what extent the fetal scalp blood lactate concentration during labor correlates with fetal scalp pH and base deficit, and metabolic acidosis at birth, and to suggest lactate cut-off values to serve as indicators for either reassurance or immediate intervention. ⋯ In the case of a non-reassuring fetal heart rate, fetal scalp blood lactate provides more accurate information on fetal acid-base status than does pH and/or BD.

Comparative StudyAntenatal diagnosis of placenta accreta leads to reduced blood loss.
Placenta accreta is one of the most devastating pregnancy complications. We sought to compare outcomes between women with placenta accreta when diagnosed antenatally or intrapartum, and to define predictors of the antenatal diagnosis. ⋯ Antenatal diagnosis of placenta accreta may reduce peripartum blood loss and the need for blood transfusion. Women with antenatal diagnosis more often have placenta previa and history of previous cesarean section, and the clinical diagnosis is more often placenta percreta.

Randomized Controlled Trial Comparative StudyLocal infiltration analgesia in urogenital prolapse surgery: a prospective randomized, double-blind, placebo-controlled study.
To evaluate the analgesic effect of high-volume infiltration analgesia in urogenital prolapse surgery and provide a detailed description of the infiltration technique. ⋯ Systematic high-volume infiltration analgesia is an effective analgesic technique in patients undergoing posterior wall repair and perineorraphy, and improves early recovery.

Comparative StudyEvaluation of the discrepancy between pH and lactate in combined fetal scalp blood sampling.
To evaluate the rate of discrepancy between pH and lactate values in fetal blood sampling (FBS). To evaluate differences in obstetric management in response to combined tests (pH and lactate) and single tests (pH or lactate). ⋯ In the combined test, discrepancies were common and occurred in half of the samples with an abnormality. Obstetric management was influenced by the discrepancy between test results with respect to ODFD rates and the time interval from the last FBS to delivery.
