Recent information provided by ESICM, AVA, GaveCelt & KDOQI indicates an increased risk of vascular access complications for COVID-19 patients in the ICU. These include:
The initial advice was to maintain a low fluid volume, however, this has been changed to ‘optimize fluid volume status’ on arrival into the ICU and then to maintain close control over fluids with all ARDS patients.
MostCare Up can assist with fluid patient management, by simply using the arterial pressure signal. Data is beat by beat and provides instant information to help guide patient management and avoid fluid overload. Unlike alternative technologies, MostCare Up does not require calibration, which avoids the introduction of additional fluids into an already fluid challenged patient population. Simple use of the passive leg raise manoeuvre will also help guide the fluid management strategy, patient by patient.
Additional Central Venous lumens or higher flow rate?
The indications are that the ARDS patients which represent ~ 50% of the current ICU population require more dedicated lumens. Whilst those patients with sepsis, ~ 25%, require both more lumens and high flow to improve hemodynamic circulation.
Besides, we have seen a move towards using antimicrobial technology for insertion via the right internal jugular vein and when using non protected technologies a move towards insertion via the Axillary vein, to increase the distance from possible respiratory seeding of the catheter.
Guidelines recommend the use of antimicrobial catheter technology when catheter dwell time is expected to exceed 5 days.
In addition to the risk factors listed above, the placement of an antimicrobial catheter should be considered in the following circumstances; to limit catheter colonization, which ultimately leads to CRBSi:
At Vygon we offer a choice of two antimicrobial catheter technologies, MultiStar & Multicath Expert. MultiStar is our 1st choice when dwell time is anticipated to be 5 days or longer.
Catheter placement and tip location (Combcard)
To ensure fast, safe catheter placement uses ECG catheters tip location techniques such as Combcard or Vygocard. This avoids the need to transfer the patient for an x-ray and the time required for the decontamination of X-Ray equipment.
Confirm the absence of a pneumothorax by using Ultrasound*
Hypercoagulation is causing multiple problems including increased rates of both venous and arterial catheter occlusion. Accordingly, we are seeing a move away from radial placement towards femoral with 18g catheters like Leadercath, using the Seldinger insertion technique.
Typically up to 30% of ICU patients were expected to present AKI and require some form of acute dialysis.
Initial reports from China indicated that AKI affected <10% of ICU patients, however, recent European data indicate that AKI is experienced by >30% of the COVID-19 ICU population. In these patients, it is advised to avoid left-sided placement of vascular access devices and to reserve the RIJ for placement of a temporary hemodialysis 15cm catheter-like Trilysecath or Dualysecath.
