THE AIM OF THE STUDY
To evaluate the effectiveness of classical corporal acupuncture for the treatment of acute and prevention of chronic postoperative pain.
MATERIAL AND METHODS
The study included 100 patients (65 women and 35 men), aged 23 to 75 years, who underwent cardiac surgery in the period from August 2023 to June 2024, who had postoperative pain 1 month after the operation. Randomized into the main and control groups of 50 people, all patients received drug therapy (lornoxicam 16 mg / day, 14 days, omeprazole 20 mg / day, 14 days and gabapentin at a dose of 1200—2700 mg / day for a long time), and patients of the main group additionally received acupuncture (IRT) — 3 procedures per week for 4 weeks (12 sessions). At the time of inclusion in the study and after 2 months, all patients had their pain intensity assessed using the VAS; the DN-IV questionnaire was used to identify the neuropathic nature of the pain. All patients were tested using the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PCS) — at the time of inclusion in the study and after 2 months — to assess the treatment results. Statistical data processing was performed using IBM SPSS Statistics and MS Excel. Differences were considered statistically significant at p < 0.05.
RESULTS
Demographic characteristics had no reliable differences — the average age in the main group was 59.07±12.46 years, in the control group — 58.63±9.17 years, p = 0.26, the male / female ratio in the main group was 17/33, in the control group — 18/32. The pain intensity according to VAS was high and did not differ between the groups, amounting to 6.7±0.8 points in the main group and 6.9±0.9 points in the control group (p=0.15). The anxiety level was 8.5±2.3 points for the main group and 8.6±2.4 points in the control group (p>0.05). The depression level was 7.7±2.2 and 7.9±2.3 points (p>0.05) for the main and control groups, the PCS scale was 16.5±4.8 and 16.9±5.0 points in the main and control groups, respectively (p>0.05). One month after the IRT course, the pain intensity according to VAS in the main group decreased to 3.2±1.2 points and to 4.1±1.5 points in the control group (p<0.05). After two months (by the end of the third postoperative month), the pain intensity was 1.9±1.0 and 2.8±1.4 points (p<0.05) in the main and control groups, the anxiety level was 3.5±1.3 and 5.9±1.9 points (p<0.05) in the main and control groups, the depression level was 4.1±0.6 and 6.4±0.8 points (p<0.05) in the main and control groups, the average score on the PCS scale was 12.7±2.4 and 19.8±2.9 points in the main and control groups, respectively. After 2 months of observation (i.e. 3 months after surgery), only 6 (12%) respondents in the main and 18 (35%) patients in the control groups met the criteria for chronic obstructive pulmonary disease.
CONCLUSION
The use of IRT in complex postoperative pain relief increases its effectiveness and reduces the incidence of chronic postoperative pain.
