Question

The learning curve for ultrasound-guided peripheral intravenous cannulation in adults: a multicenter study

Answer 1

Nurses should receive training and practice in employing ultrasonic (US) guidance in order to reduce the threshold for using it during peripheral intravenous cannulation.

Abstract:

Aim:

The main goal of the study was to estimate how many procedures beginners must complete before becoming proficient at US-guided peripheral intravenous cannulation.

Materials and procedures:

After a theoretical training session, a multicenter prospective observational study was divided into two phases: supervised life-case training and practical training. The goal was to determine how many US-guided peripheral intravenous cannulations a participant would need to complete before being considered competent in the life-case scenario. Each participant's specific learning curve was determined via cusum analysis.

Results:

A total of 1855 procedures were carried out by the 49 participating practitioners. During the initial procedure, first, try cannulation success was 73 percent; however, it climbed to 98 percent on the forty-first attempt (p 0.001). This study's overall first-try success rate was 93 percent. According to the cusum learning curve for each practitioner, proficiency was attained after a median of 34 procedures. The amount of time needed to complete a procedure successfully dropped as the practitioner's experience increased, from 14 minutes for the first procedure to 3 minutes for the forty-first (p 0.001).

Conclusions:

By adhering to a set educational programme, one can become proficient in US-guided peripheral intravenous cannulation, which increases the success rate of cannulation attempts on the first try as more procedures are conducted.
