Buff,

A Subclavian Groshong Catheter is a Port that's threaded into the Superior Vena Cava(large Vein in the heart).The Subclavian is a vein as is the Jugular.
Groshong catheters have a unique catheter tip with a valve which stays closed during neutral pressure,opens outward during positive pressure(infusion,flush)and opens inward on negative pressure(blood draw).People that require long term Antibiotics(in my case),long term Chemo or Heparin which is a blood thinner have them placed.They can draw blood from them,which is an eerie sensation.You can actually feel the blood sucking up into the tube.The only draw back is:They can become infected,no matter how good hygenical care you give.Mine became infected with a moderate growth of Klebsiella Pneumoniae.In order to place these,the patient must be in the Trendelenberg position(Freidrich Trendelenberg 1844-1924).That is where the head is lower than the feet.The surgeon makes a puncture to secure them.The reason you are placed in that position is:1)increase the volume of blood in the veins of the neck and upper extremities (during puncture of the internal or external jugular or subclavian vein for placement of a "central line").

2)decrease the pressure of the cerebrospinal fluid in the lower spinal cord and cauda equina (as for treatment of lumbar dural tear).If I don't understand a word or meaning of a word,I look it up or ask.I love learning new things.No George and I are not an item.I live in Oklahoma,if you want to know the town Iam moving to then please get me on email.
