Correlation of Preoperative Indices (serum Vit D, Calcium, Phosphorus, FAR, PLR, SII) on Intraoperative Bleeding in CRS

Correlation of Preoperative Indices (serum Vit D, Calcium, Phosphorus, FAR, PLR, SII) on Intraoperative Bleeding in CRS

The purpose of this observational study was to examine whether preoperative indicators correlate with intraoperative bleeding to facilitate control of intraoperative bleeding.

In this study, we analysed the effect of preoperative inflammation on intraoperative haemorrhage at the subjective and objective levels by measuring a number of indicators (including Vit D, Ca, P, and some ratios) in the blood specimens and by three scales.Blood test indicators can be obtained from routine tests.Three scales were obtained by the researcher after interviewing the patients, Symptom Score (0-15), where higher scores indicate more severe symptoms, Lund-Kennedy Score (0-6), where higher scores indicate higher levels of localised inflammation, Lund-Mackay Score (0-12 unilaterally and 24 bilaterally), where higher scores indicate higher levels of inflammation, and Lund-Mackay Score (0-12 unilaterally and 24 bilaterally), where higher scores indicate higher levels of inflammation.Lund-Mackay score (0-12 unilaterally, 24 bilaterally), where higher scores represent higher levels of inflammation.Final correlation of blood test indices and three scale scores with intraoperative.
