Difficult IV access
Establishing functional peripheral intravenous access is a routine in both the emergency and inpatient setting. While the traditional method of vein palpation for cannulation is successful in the majority of patients, patients with difficult intravenous access present a daily challenge to hospital staff.1
Difficult intravenous access (DIVA) is generally understood as arising when two or more punctures are performed without success, or when puncture support methods are required, or when the impossibility of obtaining peripheral access means that a central venous catheter (CVC) must be inserted.2,3,4
In fact, more than 30% of adults and up to 50% of children who require a PIVC (peripheral intravenous catheter) are reported to have challenging venous access.2
Catheter-related complications further complicate the situation. Up to 90% of short peripheral IV catheters fail before therapy completion.6
50% fail within 24 hours.7
The group of potential DIVA patients is large:
Pediatric patients, overweight and obese patients, elderly and chronically ill patients, and acute patients. They all search for deep veins.2,3
In pediatric patients, the first stick success rate is less than 35% due to thicker tissue layers.8
In overweight and obese patients, multiple attempts are usually necessary due to the thicker subcutaneous adipose tissue layer, which in turn is associated with two risks.8,9 First, the puncture error rate increases, and second, the risk of infiltration is increased. According to the WHO, obesity has nearly tripled worldwide since 1975 and is expected to increase further in Europe.10,11
Elderly and chronically ill patients, such as those suffering from diabetes, have weaker vascular systems. In the U.S., 14.5% of people are over 65 years old, and 422 million suffer from diabetes.13
Injuries in emergency and acute care patients, such as skin burns, hematomas, or dehydration, result in difficult intravenous access in approximately 11% of patients in the emergency room.14
Difficult IV access is usually associated with repeated insertion attempts and catheter-related complications. These are not only time-consuming and material-intensive, but also lead to an increased stress level among the nursing staff and the patient, combined with an increased perception of pain.9
In the emergency department in particular, the problem of DIVA has been found to negatively impact both patient safety and satisfaction. For example, multiple failed attempts to insert vascular access often result in patients becoming increasingly agitated, exhibiting "needle phobia", and losing trust in healthcare professionals. Patients may develop pain or bruising at the insertion sites, putting them at higher risk for skin injury and infection. Delayed access can further increase the time needed for necessary diagnoses or treatments such as fluid resuscitation and administration of medications or pain medications.2 Complementing this, multiple punctures may be associated with progressive deterioration of the vascular tree, termed "vascular exhaustion", which further complicates vascular access during successive contacts with the patient.15
Once cannulated, survival of IV catheters is problematic.

0%
of PIVC are terminated early due to complications such as dislodgement, infiltration or extravasation.6
Dislodgement is when the catheter loses access to the patient's vasculature and causes a forced, premature interruption of infusion therapy. Infiltration or extravasation, on the other hand, occurs when punctures do not properly target the vascular access and cause the infused solution to flow into the tissue surrounding the vascular access. This complication is particularly relevant when infusing highly irritating (e.g., vesicant) substances.6
In addition to nerves and time, repeated insertion attempts cost material above all. For example, the average cost of replacing PIVCs per sequence of IV treatment is USD 51.92.17 Repeated unsuccessful insertion of a PIVC sometimes leads to switching to more expensive and complex solutions and using central venous catheters (CVC) or peripherally inserted central catheters (PICC – peripherally inserted central venous catheter).
Both alternatives require a longer insertion process and are associated with higher material costs. However, in many cases, CVCs are inserted unnecessarily. Although patients are eligible for a peripheral IV catheter, CVC or PICC are used because of difficult IV access rather than dwell time or infusion solution.18

The average time required for a peripheral intravenous cannulation is reported to be 2.5 to 13 minutes.
To treat patients with difficult intravenous access in a time-, nerve-, and material conserving manner, the use of longer PIVC and ultrasound-assisted catheter insertion is recommended.
Long PIVCs increase catheter survival time. A longer part of the capillary stays in the vein and helps to prevent catheter dislodgements and infiltrations.16,18,20,21,22
According to Bahl et al 2019, the optimal length of the catheter in the vein is at least 2.75cm.
Furthermore, ultrasound-guided venipuncture supports first-stick success.22,23,24
