To evaluate if the implementation of a colorimetric quantitative blood loss (QBL) system during cesarean delivery improves clinical outcomes.
We conducted a retrospective cohort analysis after cesarean section before and after implementation of the Triton based colorimetric QBL system. Prevalence of postpartum hemorrhage, amount of blood products transfused, length of hospitalization, and rates of intensive care unit (ICU) admission were compared.
A total of 2221 patients were included. There were 1192 patients in the pre-intervention group and 1029 patients in the post-intervention group. There was no significant difference between groups in the prevalence of postpartum hemorrhage (8.6% vs 9.3%, P = 0.57), amount of packed red blood cells (pRBCs) transfused (45 vs 30, P = 0.41) or average length of hospital stay in days (3.0 vs 3.0, P = 0.37). There was a statistically significant decrease in ICU admissions between the pre- and post-intervention groups (2.2% vs 1.0%, P = 0.02).
There was no effect of implementation of the colorimetric QBL application system on diagnosis of postpartum hemorrhage, amount of blood products transfused, or length of hospital stay. Although a significant decrease in ICU admissions was observed, we could not determine if these transfers were hemorrhage related.
评估在剖宫产术中实施比色定量失血量（QBL）系统是否能改善临床结局。
我们在实施 Triton 比色 QBL 系统前后对剖宫产患者进行了回顾性队列分析。比较产后出血的发生率、输血量、住院时间和重症监护病房（ICU）入住率。
共纳入 2221 例患者。干预前组 1192 例，干预后组 1029 例。两组产后出血发生率（8.6%比 9.3%，P=0.57）、输血量（pRBC 比 45 比 30，P=0.41）或平均住院天数（3.0 比 3.0，P=0.37）均无显著差异。干预前组与干预后组 ICU 入住率有统计学显著下降（2.2%比 1.0%，P=0.02）。
实施比色 QBL 应用系统对产后出血的诊断、输血量或住院时间没有影响。虽然 ICU 转科率显著下降，但我们无法确定这些转科是否与出血有关。
