“…Morbidity is significantly reduced during the perioperative period in terms of deep vein thrombosis, pulmonary embolism, transfusion need, pneumonia, respiration depression, myocardial infarction, and renal insufficiency in patients to whom peripheral nerve block is applied instead of GA [ 4 , 5 ].
