Peripheral Intravenous Cannulation Using Three Different Techniques on Nursing Students
Condition: Image; Knowledge, Attitudes, Practice
Study type: Interventional

Summary: 
      Aim: The primary objective was to assess the effect of three different teaching techniques on
      the success of first-time peripheral intravenous cannulation (PVC) insertion as well as the
      vein prominence of nursing students. As a secondary objective, the authors conducted research
      on the students' PVC knowledge levels and skills performance, in the PVC procedure and the
      duration of the procedure, their satisfaction, and self-confidence in learning.

      Design: A randomized controlled trial with a pretest and posttest was conducted between
      February and July 2022, with near-infrared light visualization (n=49), isometric exercise
      (n=50), and each other's arms (n=48) with nursing students in Turkey.
    

Detailed description: 
      Aim: The primary objective was to assess the effect of three different teaching techniques on
      the success of first-time peripheral intravenous cannulation (PVC) insertion as well as the
      vein prominence of nursing students. As a secondary objective, the authors conducted research
      on the students' PVC knowledge levels and skills performance, in the PVC procedure and the
      duration of the procedure, their satisfaction, and self-confidence in learning.

      Methods: A randomized controlled trial with a pretest and posttest was conducted between
      February and July 2022, with near-infrared light visualization (n=49), isometric exercise
      (n=50), and each other's arms (n=48) with nursing students in Turkey.

      Performing the application on the NIR light visualization group: The participants in this
      group were taught to use the device, previously. The NIR light device was held by the
      researchers at 20cm. The participant performing PVC carried out the procedure on the arm vein
      of another volunteer classmate with the help of vein imaging by NIR. All interventions were
      conducted under the observation of the researchers. Two researchers made assessments
      independent of each other based on the C-PVC. The researchers used a chronometer to measure
      and record how long the PVC took. Participants were asked about the degree of vein prominence
      under NIR light after the tourniquet was applied, using inspection and palpation. The
      chronometer was started after the tourniquet was applied and stopped when the catheter
      plaster was applied. The time that it took to choose the materials needed for the PVC was not
      added to this time. The researchers recorded whether the PVC procedure was successful or
      unsuccessful. The cannula's placement during PVC was evaluated by drawing blood and returning
      it to the vein with a syringe. The PVC procedure was considered a failure if the vein was not
      opened or no blood reached the syringe. The catheter was taken out, a cotton tampon was
      applied, and the arm was elevated for five minutes whether the PVC attempt was successful or
      not. The SCLS was completed immediately after the procedure.

      Performing the application on the isometric exercise group: In this group, the participants
      performing PVC carried out the procedure by observing vein dilation after isometric exercise.
      Before the procedure, the students on whom PVC was to be performed were given two stress
      balls, and they were told how to use them for 15 minutes. The stress balls used in the study
      were 6 cm in diameter and yellow. They were of medium hardness and made of high-quality
      silicone. The participants were told to squeeze and relax the stress ball in the palm of
      their hands after counting from one to three, to continue doing this until the procedure
      began, and to concentrate on squeezing the ball. Participants were asked about the degree of
      vein prominence after the isometric exercise and tourniquet was applied, using inspection and
      palpation. The remaining stages were carried out in the same way as with all of the groups.

      Control group: The students in this group performed the PVC procedure directly on each
      other's arm veins without NIR or isometric exercise. Participants were asked about the degree
      of vein prominence after the tourniquet was applied, using inspection and palpation. The
      remaining stages were carried out in the same way as with all of the groups.
