One of the basic and important needs of hemodialysis patients is vascular access. Nursing students as members of the health team and future nurses, play an essential role in the safety management of hemodialysis patients and therefore, their training is important to support patient safety. Today, evidence-based education with the objective of explicit and rational use of the best common evidence provides sufficient and necessary knowledge in the field of safe and effective management of patients according to evidence-based guidelines for nursing students. Therefore, the present study was designed and implemented with the aim of determining the effect of evidence-based education on the knowledge of nursing students in the care of hemodialysis vascular access in 2021.

In this experimental study, 65 fourth-year nursing students of Urmia College of Nursing and Midwifery were selected and divided into two intervention and control groups. Then, in the intervention group, evidence-based training was provided to students in 4 sessions each for 1.5 to 2 hours, but the control group did not receive any training. Information was collected with demographic information and hemodialysis vascular access questionnaires, and analyzed and compared using SPSS version 16 software.

The results of this study showed that the knowledge scores of nursing students before the intervention did not differ significantly between the two groups (p=0.749). However, the scores of awareness after the intervention were significantly different in the two groups (p=0.0001). On the other hand, there was no significant difference in the scores of knowledge of nursing students about hemodialysis vascular access at the beginning and end of the study in the control group (p=0.107). Also, the scores before and after the knowledge of the students in the intervention group were significantly different (p=0.0001).

According to the findings of the research, it can be concluded that the implementation of evidence-based education was effective on the awareness of vascular access among nursing students. Therefore, it is suggested to emphasize the importance of knowledge of evidence-based guidelines in order to promote the transfer of theoretical knowledge to the bedside for nursing students.

Intravenous cannulation is needed in about 90% of patients admitted to hospitals to administer medications or replace fluids, which is difficult to perform in obese patients with diabetes.

The present study aimed to assess the effect of using near-infrared vein finder technology on the success rate of cannulation in obese patients with diabetes.

This randomized controlled trial was conducted on 92 eligible patients with type 2 diabetes and obesity at Al-Rusafa hospitals in Baghdad, Iraq, in September 2021. The subjects were divided into the intervention (n = 46) and control (n = 46) groups. However, cannulation using near-infrared vein finder technology was only performed for the intervention group. The data were collected using a demographic and clinical data questionnaire and a chronometer.

The success rates of cannulation for the first time were 60.9% and 15.2% in the intervention and control groups, respectively. The mean values of procedural time were 53.2 ± 28.9 and 94.3 ± 41.5 seconds in the intervention and control groups, respectively. The independent effects of patients’ body mass index (P = 0.002) and skin color (P = 0.040) on procedural time were significant.

The use of near-infrared vein finder technology in obese diabetic patients reduces procedural time and venipuncture attempts.

This study aimed to determine changes in microvascular endothelial function with upper arm arteriovenous fistula (AVF) creation and maturation in patients with chronic kidney disease (CKD).

This prospective cross?sectional study was performed at Hospital Universiti Sains Malaysia, a tertiary hospital in Malaysia. Forty CKD patients (stage 4–5) who were scheduled for elective AVF creation over the upper extremity for maintenance hemodialysis were recruited using conveniencesampling method. Microvascular endothelial?dependent vasodilation was measured using laser Doppler flowmetry and the process of iontophoresis preoperatively and postoperatively at weeks 2 and 6. Fistula maturation was assessed at week 6.

Thirty?two patients had successful AVF maturation. Endothelial?dependent vasodilation (acetylcholine (Ach)%) was higher (246.48 [standard deviation (SD) 209.38] vs. 104.95 [SD 43.29], P = 0.001) while systolic blood pressure was lower (142.25 [SD 21.50] vs. 162.25 [SD 13.26], P = 0.017) in this group as compared to unsuccessful AVF group. No significant changes were seen in overall microvascular endothelial?dependent vasodilation during the 6?week study period (day 0, 246.48 [SD 209.38]; week 2, 201.14 [SD 198.19]; and week 6, 203.53 [SD 145.89]).

Upper arm AVF creation does not affect microvascular endothelial function up to 6 weeks post operation and may not contribute to the success of AVF maturation. However, the lower microvascular endothelial?dependent vasodilation and higher systolic blood pressure in unsuccessful AVF subjects need to be further studied.

Access to arteries is one of the most appropriate approaches for helping chronic kidney diseases.

The aim of the present study was to evaluate the survey method of vascular surgery on the onset of ischemic limb syndrome following vascular access in dialysis patients.

In this cross-sectional study, the population study was patients with end-stage renal disease (ESRD) referring to Ahvaz Golestan Hospital in 2018. Control of limbs temperature and comparison with the other side, before and after surgery, feeling cold by the patient, control of organs pulse and comparison with the other side, pain of organs comparing to the other side, pain during the dialysis, paresthesia, and movement failure and during dialysis, and organs atrophy-ulcer were measured.

In the present study, 294 patients, including 139 women (46.94%) and 156 men (53.06%), were studied. Ischemic steal syndrome (ISS) was observed in 20 patients, that 13 cases of them had benefited from fistula approach and 7 patients used graft approach. The most common observed ISS was related to brachiocephalic fistula approach (AVF-Brachiocephalic) and then graft in arm. In non-steal syndrome group, brachiocephalic fistula (AVF-Brachiocephalic) had the most common application. In the present study, there was no significant correlation between access method and underlying diseases of high blood pressure, diabetes, and cardiac ischemic diseases.

One of themost important results of the present study was the highest existence of steal syndrome in brachiocephalic approach, which is confirmed by other studies.

Local vascular complications in pediatrics undergoing congenital cardiac catheterization are consistently reported to be the commonest regardless of the access type and side.

This is a retrospective study with data collection of multidetector computed tomography studies performed between 2016 and 2019 from 3 large cardiac centers in our country.

Totally, 190 patients who required both arterial and venous access sites were randomization into Group I or the planned ipsilateral group (the planned insertion of both arterial and venous sheaths in the same limb), Group II or the planned contralateral group (the planned insertion of arterial and venous sheaths in different limbs), and Group III or the unplanned group (unplanned vascular access sidedness after the failure of initial randomization). The incidence and types of local vascular complications during the hospital stay were recorded.Patients with the unplanned vascular access site had a higher incidence of local vascular complications, longer hospital stays, with higher needs for heparin and thrombolytic therapy than patients with the planned vascular access site. Patients with a systematically planned contralateral access site showed a lower incidence of arterial thrombosis, delayed capillary refilling time, and arteriovenous fistula, as well as lower needs for heparin and thrombolytic administration than patients with the planned ipsilateral vascular access site.

Systematic planned contralateral vascular access in patients who undergo congenital heart disease catheterization requiring both arterial and venous sheaths is associated with a lower incidence of vascular complications, especially in patients weighing less than 10 kg.

Caring for patients undergoing hemodialysis is very critical because of the disease’s complications. In the context of hemodialysis, the essential duty of nurses is to reduce the inflammation resulting from the vascular access.

This clinical trial was conducted on 101 hemodialysis patients in Montaserie and Imam Reza hospitals, Mashhad, Iran, for one month. Sampling was done by non-probability convenience method. Using random allocation, patients were placed into three groups including those who received a combination of alcohol and betadine to disinfect the vascular access site (n = 37; henceforth, group 1), those who underwent a concurrent application of alcohol after betadine (n = 33; henceforth, group 2), and the control group (n = 31). In group 1, the vascular access site was disinfected with betadine solution and alcohol mixed with a ratio of 2:1 before the dialysis initiated. In group 2, alcohol and betadine were used separately for disinfection. In the control group, the routine method of disinfection was performed using betadine, while antiseptic precautions were taken into account. During 12 sessions in four weeks, the vascular access sites of patients were evaluated for inflammation criteria postulated by the Iranian Nurses Association. Data were analyzed by SPSS16 software (significance level of P < 0.05).

Mean inflammation severity was lower in group 1 than in group 2 (P = 0.039). No significant difference was observed between group 2 and the control group (P = 0.079).

The betadine and alcohol combination can be used in similar studies because this combination is simple, inexpensive, and most importantly, effective to reduce the inflammation of the vascular access site in hemodialysis patients.
