Effect of Chlorhexidine Solution in Preventing Peripheral Venous Catheter Associated-Infection

Effects of Chlorhexidine Solutions With Different Concentrations in Preventing Peripheral Venous Catheter-Associated Infections

This research aims to determine the most effective chlorhexidine concentration to be used in preventing peripheral venous catheter-associated infections. This research is a randomized controlled double-blinded experimental design. This research will conduct between July 2022-June 2023 with 96 intensive care patients at a state hospital in Turkey. The study sample consist of 96 new insertions of peripheral venous catheters.The study will carried out as a experimental trial to compare the efficacy 1%, 2% and 4% clorhexidine gluconate and 70% alcohol in preventing infections due to catheter administrations in patients. Patients who fulfilled the inclusion criteria is randomized according to the randomization programme into three experimental groups and the control group. "Patient Information Form", "Catheter Information Form" and "Observational Form" will used to collect data.The vital findings and local infection findings of the patients that peripheral venous catheter is inserted will followed and recorded at pre-insertion and once every 24 hours for 96 hours. Culture analyze will performed from swab example taken from catheter entry location at pre-insertion,1st hour and pre removal of catheter.Data will analyzed in statistical program and p<0,05 will considered as significant.

This research is a randomized controlled double-blinded experimental design. The aim of the study is to determine the most effective chlorhexidine concentration to be used in preventing peripheral venous catheter-associated infections.The study will conducted between July 2022-June 2023 at the anaesthesia and reanimation intensive care unit of a government hospital. Sample size was assessed using G-power analysis (effect size 0.3; medium level α = 0.05; 1-β = 0.80), and it was found that for each group, 24 patients had the capability of representing the population.Patients were assigned to groups using the programme random number generator.Patients who fulfilled the criteria for inclusion will taken into the study as the experimental groups (group 1: 1% chlorhexidine; group 2: 2% chlorhexidine; group 3: 4% chlorhexidine) and the control group (group 4: 70% iso-propyl alcohol).The population of the study consisted of the patients in the intensive care unit of anaesthesia and the sample consisted of the 96 adult patients who will admitted to the intensive care unit within the dates when the study was conducted and who will insertioned peripheral venous catheter and remained inpatients for at least 4 days."Patient Information Form", "Catheter Information Form" and "Observational Form" will used to collect data. The "Patient Information Form" is consisting of 13 questions about the socio-demographic information about the patient, the "Catheter Information Form" is consisting of 13 questions about the information of the catheterization, and the "Observation Form" is consisting of 13 questions about the vital findings and local infection findings of the patients. The vital findings and local infection findings of the patients that peripheral venous catheter is inserted will followed and recorded at pre-insertion and once every 24 hours for 4 days. Culture analyze will performed from swab example taken from catheter entry location at pre-insertion,1st hour and pre removal of catheter. To perform the statistical analysis for the study, the authors will utilized the Statistical Package for Social Science (SPSS 22.0) software program. The descriptive statistics will provided in a number and percentage format. According to the Kolmogorov-Smirnov test results, key variables of the present study will analyzed using the Mann-Whitney U test for binary groups and the Kruskal-Wallis test for triple groups.and p<0,05 will considered as significant.

This research is a randomized controlled double-blinded experimental design. First experimental group, 1% chlorhexidine, n=24 patients, second experimental group, 2% chlorhexidine, n=24 patients, third experimental group, 4% chlorhexidine, n=24 patients, control group, 70% iso-propyl alcohol, n=24 patients

Effects of Chlorhexidine Solutions with Different Concentrations in Preventing Peripheral Venous Catheter-Associated Infections

Chlorhexidine solution in different concentrations (1%, 2%, 4%) will applied to the 3 determined experimental groups, and 70% alcohol solution will applied to the control group. Its effects in preventing peripheral venous catheter-associated infection will compared.

Different concentrations of chlorhexidine solutions have no effect on preventing peripheral venous catheter-related infections. 1%, 2% and 4% of chlorhexidine-gluconate solutions will compared with the 70% alcohol for skin antisepsis of PVC in ICU patients. Specimens will collected by swabbing the peripheral venous catheter entry site from the patients within before,1st and 96th hours of catheterization, respectively. The culture incubate at 37 C overnight on EMB and sheep blod agar plate. Then, the reproduction of microorganisms will identified in the culture. The presence of colonization of microorganisms in EMB blood agar indicates that gram-negative microorganism growths. The presence of colonization of microorganisms in the sheep blood agar indicates that gram-positive microorganisms growths. The absence of colonization of microorganisms in both of blood agars indicates that there is no growth.
