Outcome Measures

Primary Outcomes (2)

  • The The Verbal Category Scale

    The Scale is a pain assessment tool based on the patient's selection of the most appropriate word to describe their pain state. Patients rate their pain on a 0-4 point scale, where 0 point indicates "no pain," 1 point indicates "mild pain," 2 points indicate "severe pain," 3 points indicate "very severe pain," and 4 points indicate "unbearable pain". It was determined that the pain decreased after CoolsenSe application.

    1 Day

  • The General Comfort Scale

    It employs a four-point Likert-type scale, encompassing three sub-dimensions (relief, relaxation, and superiority-coping with problems) and 48 items. In this study, a score of 1 indicates a low comfort level, while a score of 4 represents a high comfort level. It was determined that comfort increased after CoolsenSe application.

Study Arms (2)

CoolSense Group

EXPERIMENTAL

The responsible researcher carried out the application of the CoolSense device and filled out the patient information form before the arteriovenous fistula cannulation. Meanwhile, the application of the VCS and GCS was conducted both before and after the CoolSense device's application, with the latter occurring after the arteriovenous fistula cannulation. The nephrology charge nurse was responsible for these measurements, using a single device located at the patient's bedside.

Device: CoolSense Group

Control Group

NO INTERVENTION

Patients in the control group underwent routine HD arteriovenous fistula cannulation and received HD treatment following the hospital's established protocol. Data collection tools were only administered to the participants before and after the study.

Interventions

Patients in the CoolSense group received a CoolSense device that had been pre-chilled in the freezer for a minimum of one hour. The cover of the CoolSense device was removed, and the arteriovenous fistula, whose metal tip had been cleaned with batikon, was brought into contact with the area where the arteriovenous fistula cannulation would occur. This contact was maintained for 5 seconds, involving circular movements, and the fistula cannulation took place promptly.

Masking Details
The study was designed as a single-blind, randomized, controlled clinical trial, with measures taken to minimize bias. Different individuals collected the data using the data collection form and tools, ensuring that the patients in the CoolSense and control groups remained confidential from the co-investigator and nurse responsible for administering the data collection tools, thereby implementing blinding.

Model Details: To determine the sample, power analysis was utilized. With an effect size of 0.80 and a targeted test power of 0.80 (80%), the sample size was computed as 42 patients in total (21 for each group) for both the CoolSense group and the control group. This calculation was performed using the G\*Power 3.1.9.6 software, with a significance level of α=0.05, considering the absence of prior experimental studies investigating pain scores in this context. Accounting for potential issues such as participant withdrawal or study-related mortality, each group was increased by 20%, resulting in a total of 50 patients, with 25 patients in each group.
