STEP BY STEP DESCRIPTION OF HEMODIALYSIS:
Starting hemodialysis often a frightening experience.hemodialysis machines are complicated and dialysis sessions offen are punctuated by alarms.
pre-dialysis:
1.Before or around the time the patient arrives for his sheduledsession,a dialysis machine will be prepared.there are many models of dialysis machines,But tipically in modern machines there will be a computer,CRT,a pump,and facility for disposable tubing and filters.The filters (actually the artificial kidneys)are cylindrical,clear plastic outside with the filter material inside.They are 15-18 inches long, and 2-3 inches thick.They have tubing connectors in both ends.The technician or nurse will set up plumbing on the machine in a moderately complex pattern that has been worked out to move blood through the filter,allow for saline drip,allow for various medications/chemicals to be administered.
2.The pump does not directly contact blood or fluid in the plumbing-it works by aplying pressure to the tubing,then moving that pressure point arround.Think of a disk with a protrusion in it.Put this in ti a close fitting 270 degree enclosure.
3.The patient arrives and is carefully weighed.Standing and sitting blood pressures are taken.Temperature is taken
4.Access is set up.For patients with a fistula(a surgical modification to an arm or leg vein to make it more robust,and there fore usable for high capacity blood movement required by dialysis) this means inserting two large gauge needles in to the fistula.This is painfull for the patient but there are various methods of rumbing the needles are inserted-the two most common are lignocaine9a local anesthetic injected under the skin )and also a cream called EMLA applied the skin before 45 minutes needles are inserted.
5.When access has been set up,the patient is then connected to the precconfigured plumbing,creating a complete loop through the pump and filter.
