A dialysis patient is said to be an acid accumulator for about 44 hrs (Interdialytic period) followed by 4 hrs effective period of retitration (Intradialytic period) which can be accompanied by various degrees of hypoxemia (decreased oxygen in the blood). Hypoxemia occurs because during dialysis Co2 tends to diffuse across the dialyser membrane resulting in decreased Co2 concentration in the blood (pCo2) causing hypoventilation (slow breathing rate) in dialysis patients.

Intraosseous Access For Hemodialysis
Intraosseous Access is said to be vascular access obtained from the bone which functions similar to the Intravenous access because the bone marrow of long bone contains veins that ultimately drain into the vena cava and this access is said to be a non-collapsible venous access route and considered as a standard alternative to peripheral intravenous access.
Difficult Cannulation Made Easy
The majority of AVF created does not meet the "Rule of 6s" which makes it difficult to cannulate. And many AVF have prominent bruit and thrill but veins are present deep which makes it difficult to find the vein and cannulate which if not done properly might lead to access-related complications. Because of these reasons the patient has to go back for Central Venous Catheter (CVC) or Arteriovenous Graft (AVG) as their vascular access which is higher in cost and less preferred for maintenance hemodialysis due to its high complication rate compared with AVF. To avoid patients settling with CVC/AVG there are many techniques and procedure which helps make difficult cannulation easy.
Anatomy of a Dialysis Needle
As the prescription of all dialysis patients is individualized, the needle choices should also be individualized to make dialysis treatment more effective. There are different types of AVF needles available with different specifications that play their role to meet the dialysis demands.Â
Simple Tests to Detect Serious Arteriovenous Fistula Complications in Hemodialysis Patients
The complication rate of Arteriovenous fistula (AVF) is low compared with Arteriovenous graft and Central venous catheters. Still, the most common complications associated with a mature hemodialysis arteriovenous fistula are an aneurysm, fistula thrombosis, infection, stenotic vascular lesions, access recirculation, and extremity ischemia.
