First experience of spinal anesthesia in total knee joint replacement surgery

Aim of the study. To evaluate efficacy and safety of spinal block anesthesia in total knee joint replacement surgery. Materials and methods. Prospective observational study of 67 patients underwent total knee joint replacement with spinal block anesthesia. Patient’s data, perioperative blood loss, necessity of blood transfusions, pain level and additional opioid usage were evaluated. Results. 78% of patients were younger then 45 y.o., chronic pain syndrome was observed in 31%, preop chemo was used in 27%, anemia was seen in 28%. Blood loss during the femoral bone resection was around 400 ml, during tibia and fibula bones 600 ml with total blood loss after surgery of 870 ml and 845 ml respectively. In 100%of patients there were no pain syndrome before and after the surgery. In steady state condition pain level 3 was observed in 78% and the level of dynamic pain did not exceed 4 in 74% of patients. Prolonged block anesthesia failed to systemic anesthesia in 15% of patients. Conclusion. In 85% of cases spinal block anesthesia provided an excellent control with minimal usage of narcotic agents.
