Dynamics of Stress Laboratory Findings and Their Relation to Psychoemotional State During Regional Anesthesia in Patients With Lower Limbs Injuries

Abstract

The choice of an adequate method of anesthesia for surgical treatment of lower limbs injuries remains a critical task today. Each method applied in this treatment has its advantages and disadvantages. In recent years, regional anesthesia has been the preferential method. The aim of the study. To study the stress laboratory findings and their relation to the patients’ psychoemotional state in perioperative period while performing regional and combined anesthesia. Material and methods. It was studied 60 patients aged 18-59 years, who underwent metal osteosynthesis operations due to lower limbs injuries. Surgical treatment was performed under regional anesthesia and regional anesthesia followed by sedation. The patients of both groups were conducted heamodynamics monitoring and determined the intensity of pain in accordance with visual analogue scale and stress indicators with a laboratory method. The psychoemotional state was assessed with the Spielberger-Hanin anxiety scale. Results. According to the study it was determined, that in patients, who were planned to have surgery, significant psychoemotional stress and stress concentration of hormones in the blood and their interrelation was discovered. Patients about before surgery had a relationship between situational anxiety and cortisol r=0.7; p=0.00006 in group I; r=0.6; p=0.002 in the second group. The relationship between VAS and cortisol r=0.5; p=0.04 in groups I and II. After surgery, the connection was in group I patients between situational anxiety and cortisol r=0.4; p=0.02; the relationship between insulin and the HOMA index r=0.5; p=0.01. Conclusions. Before the operation, all patients revealed significant psychoemotional stress and stressful changes in the concentration of hormones in the blood. Reliably pronounced dynamics of the indicators was with the use of combined conduction anaesthesia. Thus, the performed study allows to recommend combined regional anesthesia as the method of anesthesia choice, particularly in patients with high anxiety.
