title: Radioisotope dilution technique for measurement of blood loss associated with lower segment caesarean section.
abstract: Using a 51Cr-labelled red cell dilution technique, the blood loss associated with elective lower segment Caesarean section was measured in 30 patients, half of whom had a previous history of Caesarean section. The blood loss (mean +/- SD) was 1290 +/- 240 ml for first Caesarean sections and 1012 +/- 380 ml for repeat operations.
