we should consider the need for a PVC&#46; A venous line should not be placed as a routine act&#46;<a class="elsevierStyleCrossRef" href="#bib0285"><span class="elsevierStyleSup">17</span></a> Many practitioners prefer to prescribe intravenous drugs&#44;

of PVCs are not necessary&#46;<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">17&#44;18</span></a> Avoiding unnecessary venous catheterization is obviously the main action to prevent catheter-related bacteremia&#46; When an intravenous access is needed&#44; it is mandatory to choose the catheter type in accordance with the expected duration of catheterization and the use for which it is required&#46; Intravenous therapy planned for more than 6 days&#44; or a catheter needed for major procedures such as hemodialysis&#44; plasmapheresis&#44; chemotherapy&#44; parenteral nutrition&#44; or monitoring fluid replacement therapy&#44; among others&#44; require the use of a central line rather than a peripheral one&#46;<a class="elsevierStyleCrossRefs" href="#bib0230"><span class="elsevierStyleSup">6&#44;19</span></a></p><p id="par0045" class="elsevierStylePara elsevierViewall">Second&#44; inserting a PVC into a central vein does not make much sense&#46; If it is necessary&#44; upper extremity veins are preferable to minimize the risk of infection&#46; Insertion of a PVC does not require a sterile surgical field&#44;

The caregiver inserting the PVC can wear clean single-use gloves instead of sterile ones&#44; and the catheter must be handled from its proximal end&#46; Additional measures of asepsis are not required&#46; Nonetheless&#44; when there are doubts about adherence to these basic rules&#44; the catheter should be removed and replaced by another&#44; if needed&#46;</p><p id="par0050" class="elsevierStylePara elsevierViewall">Third&#44;

it is not advisable to maintain PVCs in place beyond 5 days&#44; mainly if they are not in use&#46;</p><p id="par0060" class="elsevierStylePara elsevierViewall">Fifth&#44; the catheter should be removed under the following circumstances&#58;

date&#44; and anatomic location of insertion&#44; results of daily inspection&#44; removal date&#44; and reason for removal should be included&#46; Electronically supported registries can facilitate data collection and analysis&#46;
