This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:
The objective of this review is to evaluate effectiveness and safety of ultrasound (UGP) or doppler (DGP) guided puncture techniques used for the insertion of central venous catheters. We will assess whether there is a difference in complication rate between traditional landmark guided and any ultrasound guided central vein puncture.
Where possible, we will also assess:
whether a possible difference could be verified for the UGP and the DGP technique;
whether a possible difference could be verified for the direct ((D) ultrasound during puncture) and the indirect ((ID) looking for the vessel by means of ultrasound and marking the puncture site on the skin; the following puncture was performed without sonographic guidance/ultrasound before puncture) approach;
whether these possible differences could be proved in all the collectives (patients (ICU, patient awake or in narcosis, adult or children), physicians's experience (advanced/inexperienced)) which we will form in our subgroup analysis; and
whether these possible differences could be proved for the internal jugular vein (IJV), the subclavian vein (SV), the femoral vein (FV) and the axillary vein (AV).
