Abstract:

Objective To analyze the roles of serum procalcitonin(PCT) and urine endotoxin determinations for guiding catheter-associated urinary tract infection(CAUTI) antimicrobial therapy. Methods Totally,180 patients with CAUTI were enrolled and classified into 3 groups,including no drug usage group(60 cases),Gram negative(G-) bacterial antimicrobial group(60 cases) and Gram positive(G+) bacterial antimicrobial group(60 cases),according to the situation of antimicrobial therapy based on serum PCT and urine endotoxin levels. The bacterial determination,drug resistance,nosocomial infection and treatment,biochemical indicators and urinary tract irritation in the 3 groups before and after treatment were compared. Results The drug usage time,dosage,nosocomial infection control time and hospital staying time in G- bacterial antimicrobial group and G+ bacterial antimicrobial group were higher than those in no drug usage group(P<0.001). The bacterial determination rate and CAUTI-related indicators had no statistical significance among the 3 groups(P>0.05). After treatment,the determination rates for resistant isolates in G- bacterial antimicrobial group and G+ bacterial antimicrobial group were lower than those in no drug usage group(P<0.05). Urinary tract irritation indicators,frequent micturition,urgent urination and dysuria,after treatment among the 3 groups had no statistical significance(P>0.05). Conclusions PCT combined with urine endotoxin determination can guide the rational drug usage for CAUTI patients.
