Buttonhole cannulation better than rope ladder cannulation for making AV fistula for dialysis
Buttonhole cannulation better than over rope ladder cannulation for arteriovenous fistula, finds a new study. Therefore it should be recommended as a routine procedure for hemodialysis.
The study has been published in the journal Medicine.
Safe and effective arteriovenous fistula (AVF) puncture techniques must be used to reduce harm to hemodialysis patients. The relative benefits of buttonhole (BH) cannulation over those of rope ladder (RL) cannulation for AVF remain unclear and inconsistent.
This systematic review and meta-analysis were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Literature searches were conducted in June 2020 in multiple scientific databases including Cochrane library, CINAHL, PubMed/ Medline, Airiti Library, National Digital Library of Theses and Dissertations in Taiwan, Google scholar, Embase, and ProQuest. They included all randomized controlled trials (RCTs) and clinical controlled trials (CCTs) that explored the efficacy of BH cannulation in hemodialysis patients. These included reports published in either English or Chinese that enrolled adults aged 18 years or older who underwent hemodialysis using an autogenous AVF. Studies that showed poor design, such as the use of a self-control group or no control group, were excluded from the analysis. The critical appraisal skills program checklist for RCTs was used to assess the quality of the evidence and RevMan software was used to perform the meta-analysis.
Results:
Fifteen studies (11 RCTs and 4 CCTs) met the inclusion criteria and were used for the meta-analysis. Meta-analysis showed that BH cannulation significantly reduced aneurysm formation (RR = 0.18, 95% confidence interval, thrombosis formation, and hematoma and showed no differences in AVR infection compared to RL cannulation.
Thus, given the benefits of BH, this meta-analysis found that BH cannulation should be recommended as a routine procedure for hemodialysis but that hospitals and hemodialysis clinics should strengthen staff knowledge and skills of BH cannulation to reduce the risk of AVF infection.
