NO IDEA WHY this safe system is not used in the army I have not a single claim but the experience from the book is CLEAR

SEE FIRST the second picture and them the first.

This is from the book :”Road accidents -medical aid” by Hanns Pacy [1972]

I just copied only the technique for you.

CENTRAL VENOUS PUNCTURE USING THE INNOMINATE VEIN HAS BEEN FOUND TO BE EXTRAORDINARILY SIMPLE. THIS VEIN HAS A DIAMETER OF 20 MM IN THE ADULT AND 5 MM IN THE NEWBORNS. IT IS FIXED BY DENSE FIBROUS TISSUE TO THE INSIDE OF THE CLAVICLE AND FIRST RIB. IT CANNOT COLLAPSE. EVEN AFTER LEAVING THE NEEDLE IN SITU.

THERE IS NO DANGER OF CLOTTING. IT MAY BE PUNCTURED REPEATEDLY AND IS CLOSE TO THE HEART.

THE METHOD CAN OF COURSE, EXCEPT FOR EMERGENCIES, ALSO BE USED FOR CONTINUAL RECORDING OF CENTRAL VENOUS PRESSURE.

NEEDLE OF 1 TO 2MM DIAMETER AND 8 CM IN LENGTH WITH A WELL-SUCKING SYRINGE OF 5 TO 10ML.

FOR A RIGHT-HANDED OPERATOR IT IS EASIER TO WORK FROM THE RIGHT SIDE. THE PATIENT LIES FLAT AND TURNS HIS HEAD TO THE LEFT. THE DOCTOR’S LEFT INDEX FINGER FOLLOWS THE LOWER EDGE OF THE RIGHT CLAVICLE FROM THE OUTSIDE INWARD TILL HE HITS THE BONY PLATEAU OF THE FIRST RIB; FROM THERE HE MOVES BACK AGAIN ABOUT 10 TO 15 MM. THIS POINT IS MARKED WITH A PENCIL. (IT IS 6 CM FROM THE MID-STERNAL LINE IN THE ADULT AND 5CM IN THE SMALL CHILD). THE NEEDLE IS PUSHED IN AT AN ANGLE OF 30 DEGREES TO 40 DEGREES TO TH FRONTAL (HORIZONTAL) PLANE, IMMEDIATELY UNDER THE CLAVICLE TOWARDS THE MEDIAL AND A SHADE UPWARD.

KEEP ASPIRATING WHILE PUSHING. THE VEIN IS STRUCK AT A DEPTH OF 3 TO 6 CM.

IF NOT REACHED ON ADVANCING TO THIS DEPTH IT IS MOSTLY REACHED ON SLOW WITHDRAWAL WHILE ASPIRATING. COMPLICATIONS ARE PRACTICALLY IMPOSSIBLE.

TIGHT CONNECTIONS OBVIATE AIR EMBOLISM.
