Cell Salvage During Caesarean Section (CSCS)
- Conditions
- Blood Transfusion
- Interventions
- Combination Product: intra-operative cell salvageCombination Product: allogeneic blood transfusion
- Registration Number
- NCT03429790
- Lead Sponsor
- Wenzhou Medical University
- Brief Summary
The purposes of this study are:
1. To compare the difference of blood loss of the patients undergoing cesarean section between intraoperative blood recovery and allogeneic blood transfusion.
2. To compare the safety of the two methods.
3. To evaluate the medical cost and the overall cost of the two methods.
- Detailed Description
Preoperative: 1.To select patients according to the criteria.2.To obtain the consent of the obstetrician, the anesthesiologist, and the patients.
Intraoperative:According to local blood transfusion guidelines, obstetric advice, anesthesia advice(tentative: before a blood transfusion maternal's Hb less than 70g/L or Hb:70-100g/l before a blood transfusion according to the blood transfusion program and doctor's determine to do the blood transfusion),those who need blood transfusion during cesarean section will be randomly assigned to the following two groups:
1. cesarean section using intraoperative blood recovery group (test group).
2. cesarean section using allogeneic blood transfusion group (control group).
The theoretical amount of blood transfusion should be based on the following formula:
The amount of blood transfusion needed (ML) \* Hb= (Hb2-Hb1) \* blood volume of blood transfusion Hb1: actual measured hemoglobin; Hb2: target hemoglobin (100 g / L) Blood volume = 100ml/kg \* body weight The difference between the actual blood transfusion and the theoretical blood transfusion should be controlled within ± 15% of the theoretical blood transfusion (in terms of hemoglobin), whether the test group or the control group.
Postoperative: Calculate the amount of bleeding in the subjects and other related indicators.
Follow up: maternal pregnancy again: detection of maternal blood group antibody IgG titer, hemolytic disease of the newborn Statistical data: the specially assigned person is responsible for the data collection. And the data is entryed by two times (the first phase: hospitalization period, the second phase: follow-up), which is by the inspectors to verify the authenticity and traceability.

- Primary Outcome Measures
Name Time Method blood loss of the subjects in 5 days of after operation in fifth day post operation calculate the changes of Hct and the amount of blood transfusion
- Secondary Outcome Measures

postoperative Hb in first day post operation in first day post operation the Hb in first day post operation
postoperative APTT in first day post operation in first day post operation the APTT in first day post operation
postoperative PT in the fifth day post operation in the fifth day post operation the PT in fifth day post operation
postoperative Hct in first day post operation in first day post operation the Hct in first day post operation
postoperative PT in first day post operation in first day post operation the PT in first day post operation

postoperative Hb in the fifth day post operation in the fifth day post operation the Hb in fifth day post operation
Total intraoperative and postoperative blood transfusion from the date of operation until the date of hospital discharge, assessed up to 7 days calculate the amount of blood transfusion
Length of hospital stay from the date of operation until the date of hospital discharge, assessed up to 7 days calculate the length of hospital stay
first mobilization from the date of operation up to first mobilization, assessed up to 7 days calculate the time to first mobilization
