Secondary Postpartum Hemorrhage Presenting With Bombay Blood Group: A Case Report.

Bombay blood group is a rare blood group. Due to its rarity and limitations for transfusions, it is often challenging to manage individuals with Bombay groups in emergencies. Here, we present a case of a 26-year-old woman with the Bombay blood group who had premature rupture of membranes at the 39th week of pregnancy while delivering a male child vaginally. The patient suffered from postpartum hemorrhage due to retention of the placenta and needed an immediate blood transfusion. During the antenatal screening, she was noted to have the O-positive blood group. Cross-matching of her blood was incompatible with O-positive blood and was identified as the Bombay blood group after having tested for anti-H antibodies. The patient underwent transfusion by identifying individuals with the O-positive Bombay blood group. As a result of this, we emphasize the diagnosis and identification of the individuals with the Bombay blood group and make blood available especially in medical emergencies.
