ABSTRACT
Objective:To evaluate the accuracy of point-of-care ultrasound in diagnosis of guidewire tip misplacement during central venous catheterization.Methods:Ninety patients of both sexes, aged 18-90 yr, with body mass index of 15.5-44.8 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅳ, scheduled for elective surgery with general anesthesia requiring central venous catheter (CVC) insertion through bilateral internal jugular veins or subclavian veins, were enrolled.The ultrasound probe was used, and the target vessel was selected.Anesthesia was induced with propofol, sufentanil and cisatracurium, and positive pressure ventilation was applied after endotracheal intubation.After central venous puncture was successfully performed under ultrasound guidance, the guidewire was inserted to a predetermined length, and the tips of the guidewire were confirmed with X-ray film and with point-of-care ultrasound including a phased array probe and linear array probe, and the results were recorded.The CVC was inserted after confirming the guidewire tip position.Agreement between the guidewire tip misplacement confirmed with point-of-care ultrasound and with bedside X-ray film was analyzed using Kappa statistics.The sensitivity, specificity, and total coincidence rate, rate of misdiagnosis, rate of missed diagnosis, Youden index, odds product, positive predictive value and negative predictive value of the guidewire tip misplacement were calculated during central venous catheterization confirmed using point-of-care ultrasound. Results:Among the 90 patients, 17 cases had guidewire tip misplacement, and the incidence of guidewire tip misplacement was 19%.Point-of-care ultrasound and bedside X-ray film were consistent in the diagnosis of guidewire tip misplacement during CVC insertion (Kappa value 0.945, P<0.05). The sensitivity of point-of-care ultrasound in diagnosing guidewire tip misplacement during CVC insertion was 97.44 %, specificity 97.78%, total coincidence rate 97.67%, rate of misdiagnosis 2.22%, rate of missed diagnosis 2.56%, Youden index 95.22%, odds product 1 672, positive predictive value 95.00%, and negative predictive value 98.88%. Conclusion:Point-of-care ultrasound can be used to diagnose guidewire tip malposition during central venous catheterization.
