Objectives: To correlate visually estimated blood loss (vEBL) with calculated estimated blood loss (cEBL) during cesarean delivery in nulliparous women. Design: correlation retrospective study. Setting: Cayetano Heredia National Hospital, Lima, Peru. Participants: Nulliparous women subjected to cesarean section. Interventions: Medical records of 160 nulliparous women atended for cesarean deliveries at term during 2011 were reviewed. Data were statically analyzed with STATA V10.1 for Windows program. Main outcome measures: Blood loss. Results: Median vEBL and cEBL were respectively 500 mL (500–600 mL) and 421.4 mL (319.85–559.65 mL) with statistical significant difference, p < 0.001. For cEBL 1 000 mL median was 1 207.80 mL (1 039.60–1 419.00 mL) and vEBL median was 500 mL (500–600 mL) with statistical significant difference, p < 0.001. Hematocrit descended 3% (3–4%). Spearman c...
