Dynamic Curve Analysis of Indicators Related to Lumbar Cistern Drainage for Postoperative Meningitis

To analyze the dynamic curve of cerebrospinal fluid (CSF)–related indices in cases postoperative meningitis after selective craniotomy and to provide reference data for clinical treatment with lumbar cistern drainage (LCD). We conducted a retrospective study LCD placement 51 patients. Primary outcomes measured included changes body temperature before intervention biochemical parameters over course 13 days catheter placement. also assessed bivariate correlation between white blood cell (WBC) count changes, polykaryocyte percentage, temperature, daily volume. Finally, we analyzed effect average volume, antibiotic choice, surgical site on WBC change curves. After LCD, there was statistically significant difference (P < 0.01) fourth day drainage. There negative volume (r = −0.56). When 250–300 mL/day, pattern consistent overall trend, no different sites > 0.05). The can decrease significantly by 4 drainage, 6–7 is ideal. An mL/day safe effective.
