Allen test for assessment of blood circulation in the hand before insertion of an arterial catheter

Patients with impaired blood circulation in the hand is assumed to have greater risk of complications due to insertion of an arterial catheter. Allen test is one of several methods that can be used to identify these people.

Question

What scientific studies are there on Allen test or other similar tests and their capability to predict complications after insertion of an arterial catheter?

Identified literature

One relevant systematic review was identified but was assessed to have high risk for bias. Two relevant primary studies were identified [1,2]. The primary studies were not assessed for risk of bias.

SBU Enquiry Service Consists of structured literature searches to highlight studies that can address questions received by the SBU Enquiry Service from Swedish healthcare or social service providers. We assess the risk of bias in systematic reviews and when needed also quality and transferability of results in health economic studies. Relevant references are compiled by an SBU staff member, in consultation with an external expert when needed.
