Evaluation of the effectiveness of regional conduction anesthesia in terms of hemodynamic parameters in the surgical treatment of patients with shrapnel wounds of the lower extremities

The purpose is to evaluate the effectiveness of regional conduction anesthesia in the surgical treatment of patients with shrapnel wounds of the lower extremities in terms of hemodynamic parameters. A prospective cohort study of patients (n=122) operated on for shrapnel wounds of the lower extremities was performed. Patients were divided into 4 groups depending on anesthesia. It has been established that the use of regional conduction anesthesia with blockade of the peripheral nerve under ultrasound control, in contrast to intravenous and local infiltration, allows maintaining the values of blood pressure and heart rate within the normal range during the entire observation cycle, including periods of surgery and dressing, as well as two-hour intervals after the performed procedures. Patients showed a statistically significant increase in the diameter of the major arteries of the lower extremities after surgery, which persisted throughout the entire period of postoperative administration of the anesthetic.
