Long peripheral catheters for intravenous access in adults and children: A systematic review of the literature.

BACKGROUND

Long peripheral catheters are peripheral intravenous catheters of 6-15 cm in length. They are commonly inserted into the forearm, antecubital fossa or upper arm using a direct Seldinger technique. They have proven to be valuable for peripheral intravenous catheters, particularly in patients with difficult intravenous access.

METHODS

We conducted a systematic review of studies reporting the use of long peripheral catheters. The following keywords were used: 'long', 'Seldinger', 'guidewire', 'peripheral', 'venous', 'intravenous', 'IV', 'vascular', 'cannula' and 'catheter'.

RESULTS

Three hundred forty-one publications were identified; 16 were included in the systematic review. There were 11 adult studies and 5 paediatric studies documenting 1288 long peripheral catheters in 1271 patients. Majority of studies (12/16) were conducted in acute care settings, (emergency department, n = 6; intensive care unit, n = 3; high dependency unit, n = 1; surgical unit, n = 2). The most frequently studied long peripheral catheter was 8 cm in length and 20 G in size. Nine studies recruited patients with difficult intravenous access; 11 studies used ultrasound guidance. Insertion success rate and mean procedural time ranged between 86% and 100% and 8 and 16.8 minutes, respectively. Average catheter duration ranged between 4 and 14.7 days (mean) and 1.1 and 9 days (median). Catheter failure occurred in 4.3-52.5% of long peripheral catheters, with leakage, infiltration and dislodgement being the most frequent causes of failure. In 3 randomised controlled trials, long peripheral catheters outperformed peripheral intravenous catheters in terms of duration and failure rate.

CONCLUSION

Long peripheral catheters are safe and reliable in both adults and children. In addition, long peripheral catheters may provide improved quality of care over peripheral intravenous catheters for multi-day intravenous therapy.
