Effect Of Open And Closed System Peripheral Catheters Used In Pediatric Services

Child, Only Clinical Trial

Official title: Effect Of Open And Closed System Peripheral Catheters Used In Pediatric Services On Insertion Success, Duration Of Stay, And Development Of Complications: A Randomized Controlled Study

Status Completed

Clinical Trial Summary

The study was conducted as a randomized controlled experimental research to examine the effects of open and closed system peripheral catheters on the success of insertion, duration of stay, and development of complications in children aged 1-18 years in pediatric services. The population of the study consisted of children admitted to the Pediatric Services of the Istanbul Faculty of Medicine, and the sample included a total of N=80 children who met the sample criteria and underwent catheter insertion between May 2023 and October 2023. The sample was divided into two groups: closed system peripheral venous catheter group (n=40) and open system peripheral venous catheter group (n=40). The data of the study were collected using a Data Collection Form, Peripheral Venous Catheter Monitoring Form, Visual Infusion Phlebitis Detection Scale, and Pediatric Peripheral Intravenous Infiltration Scale

Clinical Trial Description

The study was conducted as a randomized controlled experimental research to determine the impact of open and closed system peripheral catheters on the success of insertion, duration of stay, and the development of complications (infiltration, phlebitis) in children aged 1-18 years.

Location and Characteristics of the Study:

The research data were collected from pediatric patients in the Department of Pediatric Health and Diseases at Istanbul University Istanbul Faculty of Medicine. The pediatric services within the Department include Gastrohepatology, Neurology, Nutrition and Metabolism, Cardiology, Allergy and Immunology, Nephrology, Rheumatology, Endocrinology, and Chest Diseases, comprising a total of 47 service beds.

Study Population and Sample:

The study population consisted of children admitted to the pediatric services of Istanbul University Istanbul Faculty of Medicine between May 2023 and October 2023. The sample size was determined based on literature findings (Boztepe and Abusfia, 2015), considering a type I error rate of 0.05, a test power of 0.91 (α= 0.05, 1-β= 0.95). The minimum sample size for each group was calculated as 66 (n=33). However, to mitigate the possibility of losing cases, a total sample size of 80 patients was determined, with 40 patients in each group. Therefore, 40 patients would constitute the open system catheter group, and 40 patients would form the closed system catheter group. The selection of the sample was carried out through simple randomization based on predefined criteria for grouping the children.

Randomization:

In the study, there are two groups: the study group using closed system peripheral catheters and the control group receiving the routine procedure of the clinic with open system peripheral catheters. Children meeting the inclusion criteria were assigned to groups through a randomization process.

Subsequently, whenever a child meeting the inclusion criteria presented to the pediatric service, a nurse working in the unit, other than the researcher, asked the child to randomly select a piece of paper from a bag. If the paper indicated "control group," the child was assigned to the control group; if it indicated "study group," the child was assigned to the study group.

This randomization method, utilizing a simple and practical approach with the use of paper lots from a bag, ensures that each eligible child has an equal chance of being assigned to either the control or study group. The process helps minimize bias and ensures a more balanced distribution of characteristics across the groups, contributing to the reliability of the study results.

Data Collection:

In the pediatric service where the research was conducted, peripheral venous access and care for children were carried out by nurses using an open system catheter. The control group in this study consisted of the open system catheter group.

Data collection was performed in 6 stages:

Stage: Before the data collection process, a pilot application was conducted with 10 children to assess the suitability of the forms used in the research. Final adjustments were made to the forms after the pilot application.

Stage: Children included in the sample (aged 6 and older) and their parents were informed about the research, and verbal and written consents (informed consent) were obtained.

Stage: Patients meeting the sample selection criteria were randomly and equally distributed into two groups using the randomization method (1st group: control group with open system peripheral catheter application (n=40), 2nd group: study group with closed system peripheral catheter application (n=40)). It was ensured that the parents of children in both groups were present.

Stage: Before the procedure, the researcher filled out the "Patient Identification Form" for all children in the groups.

Stage: According to the group to which the child belonged, the researcher applied the "Peripheral Catheter Insertion and Removal Protocol." The protocol included the following steps:

Hands were washed, and necessary materials (gloves, cotton, an appropriately sized catheter for the child, 0.5% chlorhexidine-containing 70% alcohol, transparent drape, venous valve, saline solution, syringe) were prepared.

The area for catheter insertion was selected (upper extremity veins). Using aseptic technique, the catheter was inserted using the appropriate method (gloves were worn, the catheter area was wiped three times with a solution of 2% chlorhexidine-containing 70% alcohol, and it was allowed to dry; the cleaned area was not touched after wiping).

After inserting the catheter, it was secured using a transparent drape for easy observation.

For children with open system peripheral catheters, a venous valve was attached after catheter insertion to reduce movement of the catheter.

Catheter dressing was changed if there was moisture, looseness, or noticeable contamination.

Stage: After the insertion of the peripheral venous catheter (PVC), children were monitored daily using the "Daily Monitoring Form" until 48 hours after removal.

Data Analysis:

The data obtained in the research were analyzed using the Statistical Package for Social Sciences (SPSS) 22.0 program. Normal distribution analysis was conducted, and it was determined that the data did not follow a normal distribution. Therefore, non-parametric tests were employed for the analyses.

For qualitative variables, frequency and percentage calculations were performed.

For quantitative variables, mean, standard deviation, and median tests were conducted.

Categorical variables were compared using the Chi-square test, while quantitative variables were compared using the Mann-Whitney U test.

A significance level of p<0.05 was considered in the analyses. This means that statistically significant differences were considered when the p-value was below 0.05. This value represents the significance level used to determine differences between various groups in the study. ;
