MONITORING OF CENTRAL TEMPERATURE AND MAINTENANCE OF NORMOTHERMY IN THE PREVENTION OF CARDIAC COMPLICATIONS IN PATIENTS WITH ABDOMINAL ONCOLOGICAL PATHOLOGY

The aim of research. Тo study the dynamics of the central body temperature (CВT) and the frequency of cardiac complications in patients with abdominal oncological pathology, depending on the methods of intraoperative warming during laparoscopic and laparotomic operations.

Materials and methods. The results of a prospective study of the dynamics of body CBT in 99 patients with abdominal oncological pathology, depending on the methods of intraoperative warming during laparoscopic and laparotomic operations, are presented. The patients were divided into two groups: group 1 (n=51) – the control group, in which passive methods of warming were used; group 2 (n=48) – the study group, in which the air-convection method of heating and heating of infusion media were used. In group 1, laparotomy was performed in 20 (39.2%), laparoscopy in 31 (60.8%) patients, in group 2 - in 17 (35.4%) and 31 (64.6%) patients, respectively.The cardiovascular system was assessed by measuring heart rate, blood pressure, ECG recording, ultrasound examination of the heart and determination of troponin levels.

Results. It was revealed that in both groups, regardless of the type of surgical approach, the same temperature profile is characteristic. In group 1 patients with laparoscopic operations, there is a tendency to decrease the body CBT throughout the operation, reaching values of 35.7 ±0.20 ° C by the end of the operation (p<0.05 compared to the original). In group 2 patients, a slight decrease in body CBT to 35.9 ±0.11 ° C was detected only for 30 minutes of surgery (p>0.05). Comparative analysis of the dynamics of body CBT in the study groups did not reveal the advantages of laparoscopic or laparotomic operations.

Cardiac complications in the next postoperative hours were revealed in 19.6% of group 1 patients - bradycardia (13.7%), paroxysmal tachycardia (1.9%) and anginal attack (3.9%) and 6.2% of group 2 patients - bradycardia (4.2%) and paroxysmal tachycardia (2.1%).

Conclusion. Active intraoperative warming allows maintaining a stable temperature profile and reduces the number of cardiac complications in the postoperative period in cancer patients.
