Fetal blood sampling (FBS) is a medical procedure utilized to assess the condition of a fetus, particularly in situations where fetal distress is suspected. This procedure involves the careful visualization of the fetal scalp through the use of an amnioscope, which is a specialized instrument inserted into the vagina. Once the fetal scalp is adequately visualized, the physician proceeds to clean the area to ensure a sterile environment, minimizing the risk of infection. Following this preparation, a small incision is made in the fetal scalp, which is designed to be shallow, penetrating no more than 2 mm. This incision allows for the collection of fetal blood into a microtube for further analysis. Throughout the procedure, the physician closely monitors the incision site for any signs of clotting and ensures that it is healing properly. The primary goal of fetal blood sampling is to obtain critical information regarding the fetus's health, which can guide further medical decisions and interventions if necessary.
