测量指标:

Outcomes:

指标中文名:

产后48小时内累积出血量

指标类型:

主要指标

Outcome:

Cumulative blood loss within 48 hours postpartum

Type:

Primary indicator

测量时间点:

产后48小时内

测量方法:

受试者回病房后,使用会阴垫或卫生巾收集血液,每一次更换时由专业护理人员进行称重计算,纱布、会阴垫、布类等物品在使用之前先称重,使用后(血浸湿后)再次称重,前后相减所得结果的重量按血液比重换算。失血量(ml)= [胎儿娩出后接血敷料湿重(g)- 接血前敷料干重(g)] / 1.05(血液比重 g/ml)

Measure time point of outcome:

48 hours after delivery

Measure method:

After the subjects return to the ward, perineal pads or sanitary napkins are used to collect blood. Each time they are changed, professional nursing staff weighs and calculates the amount. Gauze, perineal pads, cloths, and other items are weighed before use and again after use (once soaked with blood). The difference in weight is converted based on the specific gravity of blood. Blood loss (ml) = [wet weight of blood-absorbing dressing after fetal delivery (g) - dry weight of dressing before blo

指标中文名:

产后子宫缩小率

指标类型:

主要指标

Outcome:

Postpartum uterine involution rate

Type:

Primary indicator

测量时间点:

产后6-12小时、48小时

测量方法:

以产后早期子宫体积的缩小率作为核心量化指标,计算公式为:缩小率 (%) = [(V? - V?) / V?] × 100%,其中 V?为产后6-12小时的基线子宫体积,V?为出院前的子宫体积

Measure time point of outcome:

6-12 hours and 48 hours after delivery

Measure method:

Using the rate of uterine volume reduction in the early postpartum period as the core quantitative indicator, the calculation formula is: Reduction Rate (%) = [(V? - V?) / V?] × 100%, where V? represents the baseline uterine volume at 6-12 hours postpartum, and V? represents the uterine volume before discharge
