Ketepatan Rumus Peres dan Topografi Anatomi dalam Menentukan Prediksi Kedalaman CVC pada Pemasangan Subklavia Kanan

Central venous catheter (CVC) insertion is a routine procedure in intensive care and perioperative care. Simple and amLurate method is needed to predict the optimal depth of CVC. This study evaluated the position and depth of central venous catheters by Peres formula ([height/10] -2) and Landmark measurement, and also assessed the incidence CVC insertion malposition. This was an analytic observational study. Fifty patients undergoing central venous catheter (CVC) with the right subclavian vein approach was divided into two groups: Formula Peres ([height / 10] -2) and Anatomy Topography Measurement group. The calculation result was used to determine the boundary prediction of skin fixation. CVC depth was evaluated by measuring the distance between the distal end of the CVC catheter with karina on chest radiographs. The measurement results were analyzed by statistical tests Bland Altman. In Peres Group, the mean of the distal CVC was 1,5 (0,82) cm under carina (IC 95% 1,2 to 1,9 cm), with the limit of agreement 0,0 cm to 3,0 cm. The mean of landmark groups was 0,85 (0,73) cm (IC 95% 0,5 to 1,1 cm) with limit of agreement -0.5 cm to 2,2 cm. The incidence of malposition was found similar in both groups. Both prediction methods were not amLurate to predict the depth of CVC insertion in Indonesian people.
