Manual syringe versus pneumatic pressure bag for emergency blood transfusion during cesarean hemorrhage

Comparison of Efficacy and Safety of Manual Syringing Versus Pneumatic Pressure Bag for Blood Transfusion in Patients Undergoing Cesarean Section With Major Obstetric Hemorrhage

Not applicable Interventional Aswan University · NCT07466719

This trial will test whether using manual 20 mL syringes or a pneumatic pressure bag (300 mmHg) gives safer, faster blood transfusions for women having a cesarean section who develop major obstetric bleeding.

What this trial studies

This is a prospective, single-center, randomized controlled trial at Aswan University Hospital comparing two rapid transfusion techniques used during major obstetric hemorrhage in cesarean deliveries. Participants who meet criteria for major bleeding will be randomized to receive blood either via manual syringing (20 mL syringes) or via a pneumatic pressure bag inflated to 300 mmHg. The primary safety endpoint is incidence of hemolysis; secondary endpoints include time to hemodynamic stability, total blood product use, transfusion-related complications, and hospital length of stay. The trial excludes patients with pre-existing hemolytic disorders, severe coagulopathy, or those who refuse transfusion.

Who should consider this trial

Good fit: Women aged 18–45 undergoing cesarean section who develop major obstetric hemorrhage (≥1000 mL blood loss or hemodynamic instability) and who consent to transfusion are the ideal candidates.

Not a fit: Patients with pre-existing hemolytic diseases, severe baseline coagulopathy, those who refuse blood transfusion, or patients not undergoing cesarean delivery are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the trial could identify a safer and faster transfusion method that reduces red blood cell destruction and improves stabilization for women with life-threatening obstetric bleeding.

How similar studies have performed: Direct randomized comparisons of these two transfusion techniques are scarce; observational and laboratory data suggest manual syringing can increase hemolysis but robust clinical evidence is limited.
