Brief summary

This study aimed to investigate the impact of the CoolSense method on arteriovenous fistula cannulation pain and the comfort levels of hemodialysis patients.

Detailed description

Pain is a sensation of unease that arises in response to intense stimulation of nerve endings throughout the body. It impacts individuals on various dimensions (emotional, social, physical, etc.), often leading to feelings of anxiety and fear. Pain is recognized as a subjective experience, influenced by factors such as age and previous pain encounters, shaping an individual's perception of pain. During their hospitalization, patients may undergo painful procedures repeatedly over an extended period, which can lead to increased complications, prolonged hospital stays, and even a decline in overall health. Furthermore, pain symptoms can reduce compliance with hemodialysis (HD) treatment, impacting the quality of life and comfort of HD patients. Effective nursing care interventions must prioritize the needs of patients and ensure their comfort and well-being. Comfort is regarded as the foundation of high-quality nursing care. Literature suggests that identifying and managing symptoms resulting from illness or treatment can enhance patients' comfort levels. Moreover, nurses, in their independent role, can effectively minimize pain and prevent potential complications by employing non-pharmacological treatment methods, especially in managing pain symptoms. Non-pharmacological methods are advantageous due to their affordability, applicability across all age groups, ease of use, and cleanliness. In this context, cold application stands out as one of the most effective non-pharmacological treatments for alleviating pain symptoms. Cold application mitigates pain through two primary mechanisms. Firstly, it indirectly induces an analgesic effect by reducing swelling, edema, and muscle spasms caused by trauma or inflammation. Secondly, it directly contributes to analgesia by altering the conduction of peripheral nerves. Additionally, cold application leads to a decrease in the conduction velocity of unmyelinated nerve fibers responsible for transmitting painful stimuli, thereby diminishing pain perception. In the relevant literature concerning the application of cold therapy, there is a noticeable scarcity of international studies focusing on the CoolSense device, which has demonstrated local anesthetic effects preceding medical procedures in recent years. Furthermore, there is currently no international or national study available that assesses the impact of the CoolSense device on the pain experienced during arteriovenous fistula cannulation in hemodialysis (HD) patients. In light of this gap in research, this study aimed to investigate the influence of the CoolSense Method on arteriovenous fistula cannulation pain and the comfort levels of HD patients.

Interventions

DEVICECoolSense Group

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 description

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.

Intervention model description

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.

Primary

MeasureTime frameDescription
The The Verbal Category Scale1 DayThe 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.
The General Comfort Scale1 DayIt 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.
