Ipsilateral placement of central venous catheters and dialysis catheters does not affect the distance between line tips, blood pressure or noradrenaline requirements

Debate exists about the safety of inserting central venous catheters (CVC) and central venous dialysis catheters (CVDC) ipsilaterally, lest the catheter tips lie in close proximity risking direct aspiration of vasopressors from the CVC into the CVDC. This study showed that ipsilateral or contralateral placement did not affect the distance between CVC and CVDC line tips. There were no significant adverse changes in cardiovascular parameters or noradrenaline dose when CRRT was commenced regardless of whether the lines were inserted ipsilaterally or contralaterally.
