Effect of Topical Application of Black Pepper Essential Oil and Peripheral Catheter Insertion

Introduction: The literature describes many techniques to increase vein visibility and palpability that facilitate peripheral intravenous catheter insertion. However, there is only one study examining the effect of topical essential black pepper oil on veins. The investigators aimed to determine the effects of topical application of black pepper essential oil on peripheral intravenous catheter insertion success. Methods: This randomized controlled trial was carried out on 60 patients randomly assigned to either the experimental group (n=30) or the control group (n=30) reporting to the endoscopy unit of the clinic between May 2019 and October 2019. The study results were evaluated using an information form, a catheter insertion form, and a visual analog scale (VAS). In the experimental group, black pepper essential oil was used to increase vein degree before the procedure, while in the control group, no extra interventions were applied. The time taken in determining an appropriate vein, time taken for successful catheter insertion, and the patient's and nurse's satisfaction after the process were recorded via a chronometer.
