Assessment value of lung ultrasound score combined with procalcitonin level in children with infectious pneumonia
Objective To explore the assessment value of lung ultrasound score(LUS)combined with procalcitonin(PCT)in the condition of children with infectious pneumonia(IPN),in order to provide a reference for clinical treatment.Methods A total of 115 children with IPN treated at the Fourth Affiliated Hospital of Yan'an University from June 2021 to June 2023 were selected as the study participants.According to the severity of the condition,the 115 children with IPN were allocated to a mild group(n=42)and a severe group(n=73).The children's clinical data and test results were collected,including basic information such as gender,age,type of infection,and number of fever days,as well as routine blood test,C-reactive protein(CRP),neutrophil-to-lymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).The receiver operating characteristic(ROC)curve analysis was used to as-sess the value of LUS score combined with PCT level in IPN condition;multifactorial logistic regression analysis was used to explore the influencing factors of IPN children's condition.Results The LUS scores and PCT levels in the severe group were signifi-cantly higher than those in the mild group(P＜0.05).The areas under the curve(AUC)for assessing IPN condition by LUS score and PCT level were 0.791(95％CI:0.746-0.841)and 0.837(95％CI:0.792-0.887),respectively.The AUC for assessing IPN condition by LUS score combined with PCT level was 0.953(95％CI:0.908-0.998).The results of multifactorial logistic regression analysis showed that fever duration≥4.5 days(OR=2.056,95％CI:1.243-3.403),CRP≥21.08 mg/L(OR=2.303,95％CI:1.327-3.994),LUS score≥19.0 points(OR=2.901,95％CI:1.756-4.791),and PCT≥3.48 ng/mL(OR=3.056,95％CI:1.905-4.901)were independent risk factors for children with IPN(P＜0.05).Conclusion High levels of LUS score and PCT are risk factors for IPN condition,and LUS score com-bined with PCT level can be used as an important indicator for assessing the condition of children with IPN,with better as-sessment efficacy when used in combination.
