Which hematologic problem significantly increases the risks associated with pulmonary artery (PA) catheter insertion?LeukocytosisHypovolemiaHemolytic anemiaThrombocytopenia
ThrombocytopeniaPA catheter insertion carries a significant risk of bleeding, which is increased when the patient has low levels of platelets. Leukocytosis, hypovolemia, and anemia are less likely to directly increase the risks associated with PA insertion.
Thrombocytopenia is the hematologic problem that significantly increases the risks associated with pulmonary artery (PA) catheter insertion. Thrombocytopenia is a condition in which the platelet count in the blood is lower than normal. Platelets are important for blood clotting, which is essential to prevent excessive bleeding after a procedure like PA catheter insertion.
During the procedure, the catheter is inserted into the pulmonary artery, which is a blood vessel that carries deoxygenated blood from the heart to the lungs. In patients with thrombocytopenia, the platelet count is too low to form clots to stop bleeding that may occur during or after the procedure. This can lead to significant bleeding or hemorrhage, which can be life-threatening. Therefore, thrombocytopenia is considered a significant risk factor for PA catheter insertion.
Patients with thrombocytopenia may require platelet transfusions before undergoing the insertion procedure to reduce the risks associated with bleeding. It is important to carefully monitor platelet counts and other relevant parameters in patients with thrombocytopenia before, during, and after the PA catheter insertion to minimize the risk of complications.
