Question

)CASE STUDY i-May is scheduled for a hemicolectomy due to carcinoma of the transverse colon. Virginia -May is nseas old and an incidental splenorthaphy is completed dunng the surgery. She receives a blood transhusto s a blood transfusion during the surgical procedure the surgical technologist, you notice blood pooling in the abdomen during the transverse colectomy fy the surgeon of your observation but do not ask for the cell saver/perfusionist. Why? You circulator how much blood is in the suction canister. What information does the surgical technologist need to give to the team to help determine the amount of blood loss? Why? d. The circulator weighs the sponges. How is blood loss calculated from weighing the used sponges? i. The patient's blood type is B negative. What does this mean? 5 Blood is brought to the OR. How is the blood product verilied prior to administration? 192 Section 2 Principles and Practice of Surgical Technology CASE STUDY 1 (Continued) 6. After the blood is started, the patient's blood oxygen level (pulse oximeter reading) drops to 85 percen What should be done? CASE STUDY 2

Answer 1

1. The abdominal surgery involving the intestine when cut open pours a lot of metabolites, this mixes with the blood, this activates the clothing factors in the blood and will lead to DIC if autotransfused

2.The technologist must give a value of the amount of blood in the suction canister taking into account the amount of blood in the suction tube also and give it in ml or litres

3.The sponges are weighed before surgery and the during the surgery the soaked sponges are weighed the difference in weight between the two gives the approximate amount of blood loss

4. This means the patient has B antigens A antibody and Rh antigen is absent

5.Blood label is first checked for expiry, blood group, whether it is whole blood or component of blood,then a small drop of the blood from the bag is mixed with the patients serum to test for cross matching

The type of anticoagulant used in the blood should also be noted

6. After starting the whole blood there is effect of dilution which first causes the fall in oxygen duration later this recovers
