ABSTRACT
Objective:To explore the characters of CDU imaging anatomy and results of clinical application of perforating branch of median cubital vein, and to find the evidence of utilizing perforating vein to establish high level hemodialysis access.Methods:From November, 2016 to October, 2019, 150 median cubital veins in 75 persons were observed by CDU. And the inner diameter and length of the perforating branch were measured Perforating branches of median cubital vein were categorized with ultrasonic imaging anatomy. Thirty-eight chronic kidney failure patients who can not build forearm fistulas were operated by end-to-side anastomosis between perforating branch vein and brachial artery to build hemodialysis access. The blood flow of fisultas was measured,the mature period of fisultas was recorded. The length of available vessels of fisultas was measured and the long-term utilization rate of fisultas was counted.Results:Perforating branch of median cubital vein was always located in a little below elbow near brachial artery, the rate of occurrence was 94.0%. It was sent out at intersection of veins. There were 4 types of perforating vein in image-anatomy. There was no significant difference in vessel length and vessel inner diameter between different types ( P>0.05) ; All the 38 patients with mature fistulas could meet the needs of hemodialysis. The available vascular length of fistulas in type I and type II patients was better than that in type III ( P<0.01), and the long-term utilization rates of fistulas in type I, type II and type III were 84.6%, 85.7% and 72.7%, respectively. There was no significant difference in blood flow and mature period between different types ( P>0.05) . Conclusion:It is most safe and reliable to use the type I and type II of perforating branch of median cubital vein to make the high level fistulas , which can provide a safe and efficient hemodialysis access for the patients with forearm vascular drain, elderly diabetes patients and difficult fistulas with repeatedly thrombosis.
ABSTRACT
Objective To assess whether it have difference between mannitol combined with glycerin fructose and only use mannitol for the treatment of cerebral hemorrhage ,which provides relevant evidence‐based basis for guiding clinical treatment of cerebral hemorrhage .Methods We used literature retrieval through to the China national knowledge internet (CNKI) ,China biolo‐gy medicine disc ,VIP Chinese periodical database ,Wanfang data knowledge service platform and manual retrieval ,and formulate the inclusion and exclusion to screening literature ;and using the Jadad quality evaluation method to evaluate literature which had been included ,heterogeneity inspection at the same time .If the effect of multiple resulted ,we used fixed effect model ;on the other hand , used a random effects model .Results Mannitol combined glycerol fructose significantly improved symptoms and nervous function in patients with cerebral hemorrhage ,and the difference was statistically significant (RR=1 .12 ,95% CI:1 .03 -1 .22 ,P<0 .01);mannitol combined glycerol fructose significantly decreasd impaired renal function and complications (RR=0 .34 ,95% CI:0 .25-0 . 47 ,P<0 .01);mannitol combined glycerol fructose significantly decreasd severe unbalance of electrolyte after taking the medicine (RR=0 .31 ,95% CI:0 .19-0 .49 ,P<0 .01) .Conclusion Compared to use mannitol only ,combination with mannitol and glycerin fructose could effectively improve the prognosis of patients with cerebral hemorrhage ,and reduce the side effects .
