Title: Intravenous catheter application and management ABSTRACT Objectives:With the extension of patients with dialysis age, population aging and diabetes, hypertension, peripheral vascular disease, the incidence increased year by year, autogenous arteriovenous fistula of the establishment of more difficult, its complications have in part withinconsistent with long-term dialysis fistula failure is the main problem facing patients.This article summarizes the hospital for 15 years to 937 cases (1226 times) hemodialysis patients with autogenous arteriovenous fistula of the clinical data to study the impact of arteriovenous fistula success factors, and assess the different periods of surgical procedure, surgical site of the arteriovenousthe impact of fistula surgery. Methods:A retrospective on the Jan 2005 - Oct 2009 our hospital in October autogenous arteriovenous fistula in 937 cases of clinical data and laboratory examinations data for investigation.Each patient's sex, age, primary disease, dialysis time and operation time of the general situation, location, manner, 24 hours, fistula patency, surgical conditions and postoperative complications secondary examination results.Calculate the success rate of surgery to explore the different stages of age, primary disease, blood pressure, blood sugar, blood lipids, hemoglobin, cardiac function and vascular factors, thrombosis success of internal fistula to compare the body fistula from different parts in different periods, differentapproach to surgical success rate Results:1, from January 1994 -2 008 years, in October the first, second and third phase of the operation success rate was 93%, 91%, 90% and the total success rate was 90.29%, no significant difference (P> 0.05).2, three stages of nasopharyngeal pot forearm arteriovenous fistula was no significant difference in clinical effect (P> 0.05).3, the establishment of vascular anastomosis end to side arteriovenous fistula and superior to reason and side to side anastomosis, the difference was significant (P <0.05). Conclusion:1, since the arteriovenous fistula is the main hemodialysis vascular access, leading to fistula failure is mainly due to thrombosis, the elderly, diabetes, low blood pressure, hyperlipidemia, preoperative risk factors is the control of blood glucose, blood lipids, surgery to improve operating skills, after appropriate anticoagulant, to prevent low blood pressure can increase the success rate of fistula.2, nasopharyngeal pot forearm arteriovenous fistula was no significant difference in clinical effect, patients with vascular conditions are good, nasopharyngeal pot is the preferred site.3, the establishment of end to side anastomosis arteriovenous fistula is the preferred surgical procedure.
