“…Brant (1966) distinguished between elective and emergency caesarean sections and he measured blood loss meticulously in both situations. The average measured blood loss was 1068 ml in 22 elective sections and 1106 ml in 14 emergency sections.…”

“…Ten of the 22 women delivered by elective section required blood transfusions either during or after the Operation com‐pared with only one of the 40 women in our study. An impor‐tant finding in the study by Brant (1966) was that the surgeon under‐estimated the volume of blood loss in 17 of the 20 elective sections where blood loss was estimated and in 13 of the 14 emergency sections.…”

“…The prevention and manage‐ment of anaemia and any other pregnancy associated compli‐cations are among the fundamental objectives of antenatal care. Accurate estimation of the volume of obstetric haemor‐rhage is also very important (Brant 1966; Brant 1967; Anonymous 1967). Because of the dispersion of blood lost at caesarean section, accurate estimation is often difficult (Wilcox 1959).…”

Objective To measure intra‐operative blood loss at elective lower segment caesarean section and to compare estimated wtih measured blood loss. Design Prospective observational study. Blood loss was measured in patients who underwent lower segment caesarean section in the course of routine hospital activity. Setting Tsan Yuk Hospital (Hong Kong), which is affiliated to the University of Hong Kong, 1990–1991. Subjects Forty women (mean age 29 years) with singleton pregnancies (mean gestation 38 weeks) delivered by elective lower segment caesarean section under general anaesthesia (mean birthweight 3177 g). Main outcome measure Intra‐operative blood loss measured by the alkaline haematin method (intra‐assay co‐efficient of Variation 2.2%). Results The mean measured blood loss was 487 ml (SE 40, range 164–1438). The mean estimated blood loss was 425 ml (SE 31) range 100–1300; mode 400). Observer error in estimating blood loss was higher if measured blood loss >600 ml. One patient received a blood transfusion and another had a post‐operative haemoglobin level <10.0g/dl. Conclusion Blood loss at elective lower segment caesarean section was usually <500 ml and was estimated with reasonable accuracy. However, there was a tendency to under‐estimate blood loss when the measured loss exceeded 600 ml.

“…C Acta Obstet Gynecol Scand 80 (2001) Confidential Enquiries into Maternal Deaths in the United Kingdom, four out of five deaths due to primary postpartum hemorrhage were associated with cesarean section (2). The amount of blood loss during a normal delivery may be considerable (3,4) but the cesarean section is associated with significantly greater blood loss (5)(6)(7). Oxytocics have been routinely used during cesar-ean sections in an attempt to reduce the bleeding as most of this bleeding occurs from the uterus after the delivery of the fetus.…”

Acta Obstet Gynecol Scand 2001; 80: 245-250. C Acta Obstet Gynecol Scand 2001 Background. Oxytocics are routinely used in an attempt to prevent excessive blood loss during cesarean section. Misoprostol, a potent uterotonic agent, has been reported to be useful in the prevention and treatment of postpartum hemorrhage by several investigators but its use during cesarean section has not been described. The objective of this study was to randomly compare the effectiveness of oral misoprostol with intravenous syntocinon on blood loss during elective cesarean sections under regional anesthesia. Methods. Sixty pregnant women were randomized either to receive misoprostol 400 micrograms orally or syntocinon 10 IU intravenously during cesarean section. The primary outcome measure was intra-operative blood loss as estimated by physicians, and by values of preoperative and postoperative hemoglobin concentration and hematocrit. Demographic characteristics of the subjects and outcomes were compared using c-square test for categorical and two-sample t-test for continuous data. Results. Baseline characteristics in terms of age, body weight, parity, gestational age and indications for cesarean section were similar in both groups. The estimated blood loss was 545 ml (CI 476-614) in misoprostol group and 533 ml (CI 427-639) in syntocinon group (pΩ 0.85). Differences in preoperative and postoperative hemoglobin and hematocrit values were also similar in both groups. Two women in the misoprostol group and three in the syntocinon group (pΩ0.64) required additional oxytocics. One patient in each group required blood transfusion. No serious side effects were noted in either group. Conclusion. Oral misoprostol appears to be safe and as effective as intravenous syntocinon in reduction of intra-operative blood loss during elective cesarean section under regional anesthesia and merits further investigation.
