MATHEMATICAL PREDICTION OF CHANGES IN THE LEVELS OF CD40-CD40L TRANSMEMBRANE PROTEIN SYSTEM ACROSS DIFFERENT ANALGESIA TECHNIQUES IN CHILDREN

The impact of the CD40-CD40L on the development of non-communicable neurological conditions is determined by abnormal CD40 expression and may be detrimental to nervous tissue function. Pain is one of the earliest psychophysical functions to develop. Postoperative complications causing pain should be addressed immediately. Regional analgesia techniques can speed up children’s recovery and reduce the need for opioids. They can also lower the incidence of postoperative nausea and vomiting, respiratory complications, and postsurgical pain intensity.The aim of this study was to present a mathematical model that predicts changes in CD40-CD40L levels in children who underwent surgery under various analgesic modalities within the fi rst fi ve days postoperatively. The autoregressive probability model was used to predict the behavior of the experimental data function within 29 days after surgery.Material and Methods. The children were divided into three groups. Group I consisted of 33 children who underwent anterior abdominal wall surgery under general anesthesia with morphine. Group II comprised 27 children who underwent anterior abdominal wall surgery under general anesthesia with the transversalis fascia plane block (TFPB). Group III included 27 children who underwent anterior abdominal wall surgery under general anesthesia with the TFPB, combined with the quadratus lumborum block 4 (QLB-4) via a single injection. The serum CD40L levels were evaluated using the immunoenzymatic assay method. The autoregressive model method based on the Burg algorithm was used to predict the behavior of the experimental data function. To automate the calculation of predictions based on the Burg method, the ‘predict’ function in РТС MathCad Prime 7.0 software was used. All clinical and laboratory studies were conducted in accordance with the World Medical Association Declaration of Helsinki ‘Ethical Principles for Medical Research Involving Human Subjects’. The study is a fragment of the research project of the Department of Children Diseases of Postgraduate Medical Education Faculty, Ivano- Frankivsk National Medical University «Health Status and Adaption of Children from the Precarpathian Region with Somatic Diseases, Their Prevention» 2021-2026, state registration number 0121U111129.Results. On the fi fth day after surgery, the serum CD40-CD40L levels were highest in children who received conventional opioid analgesia. There was no signifi cant diff erence observed between children in the TFPB and TFPB+QLB groups. On the 29th day after surgery, the predicted CD40-CD40L levels were lowest in children who received conventional opioid analgesia combined with the TFPB+QLB.Conclusions. The fi ndings obtained confi rmed the positive eff ect of combined analgesia using opioids and regional nerve block TFPB+QLB in children who received anterior abdominal surgery on suppressing immune mechanisms of pain syndrome involving the CD40-CD40L signaling system.
