ABSTRACT
Objective:To evaluate the effectiveness and safety of ultrasound-guided hydrostatic reduction for pediatric acute intussusception.Methods:One thousand eight hundred and thirty patients with acute intussusception diagnosed by ultrasound in Shenzhen Children′s Hospital from September 2017 to July 2020 were treated with ultrasound-guided hydrostatic reduction method. The therapeutic effects, complications and ultrasonic features were observed.Results:Among 1 830 cases, 1 791 cases were diagnosed as primary intussusception, and 39 cases were secondary intussusception. The overall rate of successful ultrasound enema reduction were 1 780/1 830(93.7%) patients. All 50/1 830(2.7%) patients underwent surgery after unsuccessful enema reduction, including 42 cases of primary intussusception, and 8 cases of secondary intussusception. The complication of intestinal perforation occurred in 3 cases (0.16%), and there were no deaths.Conclusions:Ultrasound-guided enema reduction for pediatric acute intussusception is an effective and safe method without radiation exposure, and can be used as the preferred method for non-operative treatment of intussusception.
ABSTRACT
Objective To evaluate the value of lung ultrasound score (LUS) in the quantitative assessment of the severity of neonatal respiratory distress syndrome (NRDS) and the value of clinical diagnosis and treatment.Methods Totally 74 NRDS cases and 30 normal neonates were studied.LUS was compared with X-ray examination,clinical data,ventilator assisted ventilation and ventilator parameters.ROC curve was used to calculate sensitivity and specificity of LUS to predict the severity of NRDS and application of invasive ventilator treatment.Results The main findings of the lung ultrasound in NRDS included diffuse distribution of dense B line,disappeared A line,pleural line abnormalities,decreased pulmonary slip sign and pulmonary consolidation.LUS in patients with NRDS was significantly correlated with X ray grades,clinical grades,assisted ventilation mode grades,number of days on ventilator and ventilator parameters (all P＜0.05).LUS value to predict mild,moderate and severe NRDS were 13.0,22.5,and 29.5,respectively.The best cutoff point for LUS to predict the adoptation of invasive assisted ventilation was 22.5,which had sensitivity of 86.0 ％ and specificity of 64.5 ％.Conclusion LUS can be used to diagnose and evaluate the severity of the desease,and to guide the clinical diagnosis and treatment.
