Introduction. There is uncertainty of evidence regarding the effectiveness and safety of regional analgesic blocks during emergency care for wounded patients with combat trauma of the extremities at Role 2 medical treatment facilities and during interhospital transportation.

Objective. To optimize perioperative analgesia regimens for wounded patients with combat trauma of the extremities at Role 2 medical treatment facilities and during interhospital transportation based on a comparative assessment of the impact of regional or systemic analgesia on pain intensity and cortisolemia levels over time.

Materials and Methods. A prospective study included 100 patients with isolated combat trauma of one extremity. Patients were divided into two groups: Group 1 (n = 50) received systemic analgesia only, while Group 2 (n = 50) received ultrasound-guided regional anesthesia. Pain intensity was assessed over time using a Visual Analog Scale (VAS), additionally the level of cortisol in plasma was also measured. Study parameters were registered in four stages: 1st stage – at the time of admission to the Role 2 medical treatment facilities; 2nd stage – at the completion of surgical intervention; 3rd stage – at the beginning of interhospital transportation; 4th stage – at the completion of interhospital transportation.

Results. Between the 1st and 2nd stages, both groups demonstrated significant changes in VAS and Cortisol levels (p < 0.05, respectively). At the 2nd stage, a significant intergroup difference was observed for VAS 2 (p < 0.05), whereas Cortisol 2 levels did not differ significantly between groups (p = 0.17). Between the 2nd and 3rd stages, Group 1 showed significant changes in both VAS and Cortisol values (p < 0.05 respectively), while in Group 2 no significant change in VAS was observed (p = 0.11), despite a significant change in Cortisol levels (p < 0.05). At the 3rd stage, intergroup differences remained significant for VAS 3 (p < 0.05), with no significant difference in Cortisol 3 levels (p = 0.41). Between the 3rd and 4th stages, significant changes in VAS and Cortisol were observed only in Group 1 (p > 0.05 respectively), whereas no significant changes were detected in Group 2 (p = 0.07 and p = 0.38 respectively). At the 4th stage, significant intergroup differences were found for both VAS 4 and Cortisol 4 (p < 0.05 respectively).

Conclusions. The study results confirm that optimizing perioperative analgesia regimens at Role 2 medical treatment facilities and during interhospital transportation allows for minimizing systemic stress response manifestations, significantly improving treatment outcomes for wounded patients, and remains a priority task of modern military medicine.
