Fertilization & Early Development
Fertilization occurs when a sperm cell merges with an egg cell, creating a zygote, which is the first stage of a new life. This process takes place in the fallopian tube. The zygote then undergoes rapid cell division, known as cleavage, forming a multi-cellular structure called a blastocyst. As the blastocyst moves toward the uterus, it continues to divide and develop. Approximately 5-7 days after fertilization, the blastocyst implants itself into the uterine lining, initiating pregnancy. Early development involves the formation of the foundational structures and systems that will shape the embryo.

Massive Transfusion Protocol
Massive Transfusion Protocol (MTP) is a standardized medical procedure activated in cases of severe hemorrhage, typically involving the rapid administration of large volumes of blood products. The goal is to restore circulating volume, maintain hemostasis, and prevent the lethal triad of hypothermia, acidosis, and coagulopathy. MTP usually involves a balanced ratio of packed red blood cells, plasma, and platelets, often in a 1:1:1 ratio. Early activation and coordination among trauma teams, laboratory services, and blood banks are essential for its success.
