Clinical value of procalcitonin detection in neonatal necrotizing enterocolitis / 中国综合临床

ABSTRACT

Objective To investigate the clinical value of of procalcitonin detection in neonatal necrotizing enterocolitis (NEC).Methods Sixty cases eligible NEC infants were randomly divided into observation group and control group(n=30 each group).All the infants were divided into Ⅰ grade group(19cases),Ⅱ-Ⅲ grade group(41 cases) according to NEC classification.All infants received PCT detection after NEC diagnosis.The observation group received antibiotic treatment base on the serum PCT levels.The control group received antibiotic treatment according to treatment routine and physician's clinical experience.Results PCT increased in 28 (46.7％) of the 60 NEC infants.In the Ⅰ grade group and Ⅱ-m grade group,the proportion of PCT increased cases were 26.3％,61.3％ respectively,and the PCTmax in PCT positive cases were (0.81±0.25) μg/L,(1.76±0.89) μg/L respectively,the differences were signifiacnt(x2 =4.627,t=-2.608,P＜0.05).The time of antibiotic usage in observation group was significantly less than that in control group ((4.9±3.0) d vs.(8.6±2.5) d,t=-3.645,P＜0.01).The fasting time and the cure time of the two groups had no significant difference (P＞ 0.05).Conclusion PCT detection can help to understand the cause and severity of NEC.Using antibiotics according to PCT levels can reduce the time of antibiotic usage without affecting the effect of the NEC treatment.
