Final answer:
Crystalloids, colloids, packed red blood cells (RBC), and fresh frozen plasma (FFP) are commonly used fluids in managing massive obstetrics hemorrhage.
Step-by-step explanation:
Commonly used fluids for managing massive obstetric hemorrhage include crystalloids, colloids, packed red blood cells (RBC), and fresh frozen plasma (FFP).
Crystalloids are salt solutions that contain electrolytes and are used to replace fluids lost during hemorrhage. They help restore blood volume and maintain blood pressure.
Colloids are solutions that contain larger molecules, like albumin or starch, which help to increase blood volume by drawing fluid into the blood vessels.
Packed red blood cells (RBC) are used to replace lost red blood cells and improve oxygen-carrying capacity.
Fresh frozen plasma (FFP) contains clotting factors and is used to help control bleeding.
