Summary

Effect of iPACK block on NLR and PLR following knee arthroplasty

Detailed description

The NLR is a sensitive indicator of inflammation confirmed in numerous studies and has a predictive and prognostic value. NLR is a cheap, simple, fast-acting, readily available stress and inflammation parameter with high sensitivity and low specificity. Dynamic changes in the NLR precede the clinical state for several hours and may alert clinicians early about the ongoing pathological process. NLR is a new promising marker of cellular immune activation, an important indicator of stress and systemic inflammation. It opens a new dimension for clinical medicine to understand better the biology of inflammation, the linkage, and antagonism between innate and adaptive immunity, and its clinical consequences for health and disease. NLR is affected not only by surgical trauma but also by the method of anesthesia. In recent years, the influence of regional anesthesiology on reducing the inflammatory response after surgical procedures has been emphasized. However, there have been very few studies evaluating the effect of various methods of anesthesia on the NLR. This is the first study to investigate the effect of regional anesthesia on the NLR and PLR in patients undergoing knee replacement surgery.
