PurposeThe role of positive endexpiratory pressure (PEEP) for successful cannulation of the subclavian vein (SCV) remains inconclusive. The aim of our study was to assess the effect of different levels of PEEP on distance from SCV to parietal pleura (DVP) and on the cross-sectional area (CSA) of the SCV.MethodsInvasive mechanically ventilated adult patients with a clinical indication for a stepwise PEEP-trial (0, 5, 10, and 15 cm H2O) were included in this prospective observational single-center study. Ultrasound examinations of SCV were performed with a linear ultrasound probe using the infraclavicular view. DVP and CSA were measured on the right and left bodyside. Examinations were repeated at each PEEP step.Results27 patients were enrolled (12 female; 60±21 years; BMI 24.6±4.9 kg/m2; 20 patients on controlled, 7 on assisted ventilation). A statistically significant increase of DVP in the in-plane view was found on the left side which was not clinically relevant. No significant differences of DVP were observed in all other views. PEEP induced changes in CSAs were statistically significant but clinically not relevant on both sides. The largest change in CSA (2mm2) was observed when comparing PEEP 10 with PEEP 0 cm H2O.ConclusionA stepwise PEEP increase was not associated with clinically relevant changes of the DVP and CSA. Thus, a PEEP-optimization for the cannulation of the subclavian vein is not indicated. |
