ObjectiveTo investigate the status quo of implementing ultrasound (US)-guided epicutaneo-caval catheters (ECC) tip location for neonatal patients in 31 provinces.MethodsThe convenience sampling method was used to investigate the nursing managers and ECC (or intravenous therapy) nurses of 91 hospitals in 31 provinces from October 29 to November 10, 2021.ResultsThe survey involved a total of 182 medical staff, including 91 managers and 91 nurses, and 91 institutions, including 22 children's hospitals, 49 general hospitals and 21 maternal and child health care hospitals. Sixteen hospitals (17.6%) carried out US-guided ECC for neonatal patients; 176 subjects (96.7%) of the 91 hospitals had known about or heard of the technology of US-guided ECC. The low awareness of operators of the tip location of ECC catheters in children under ultrasound guidance (OR = 2.690, 95% CI = 1.163–6.221), limited conditions in existing wards (OR = 2.953, 95% CI = 1.285–6.790), and insufficient funds (OR = 2.836, 95% CI = 1.149–7.004) were the independent risk factors responsible for the failure to carry out ultrasonic-guided location of ECC tips in newborns.ConclusionThe popularity of neonatal US-guided ECC location was seriously hindered by factors such as a low awareness rate of the project, the low qualification certification rate of the nursing staff, a flawed performance allocation system, and the lack of a professional team, among other factors.
ObjectiveThis study aimed to compare the applications of bedside ultrasonography (US) and bedside chest radiography (CR) in positioning peripherally inserted central venous catheter (PICC) at Neonatal Intensive Care Units (NICUs).MethodsThe study is a prospective before and after self-control clinical trial. A consecutive series of 181 neonate patients were finally enrolled for PICC placement. CR, followed by US, was used to evaluate and readjust the sites of catheter tips. The imaging capability for PICC key structures, fluctuation of the measured data, measurement of tip-to-atrium distance, operation time, infants' body temperature changes, and direct expenses of the two imaging modalities were obtained and compared.Results(1) Comparison in viewing PICC key structures: the display rate of catheter tip, SVC-and-right-atrium junction, IVC-and-right-atrium junction and tip-to-atrium distance is 99.47%, 100%, 100% and 99.47% for US and 100%, 98.42%, 97.37% and 95.79% for CR, respectively. (2) Fluctuation of the measured data by US and CR: the tip-to-atrium distance measured by US is 0.631 (0.435–0.820) cm, and that measured by CR is 0.593 (0.210–0.825) cm. US showed a narrower range of datum variance. (3) Consistency between US and CR: for consistency analysis, the Kappa coefficient (κ) was 0.843 (P < 0.05), showing their favorable consistency. (4) Comparison of operation time and infants' body temperature drop: for a CR exam, the time period taken was significantly longer than that of US (59.7 ± 26.33 vs. 79.6 ± 28.06, P < 0.001); and CR operations caused a significant babies' body temperature drop compared to US (0.14 ± 0.11 vs. 0.34 ± 0.19, P < 0.001). (5) Comparison of the direct expenses: the total cost for CR positioning was significantly higher than that for US (¥153.99 vs. ¥143, P = 0.026).ConclusionUS exhibited superior traits to CR in the positioning of PICC tip. It could be promising for routine use in NICU.
