hypodermoclysis

(medicine) Subcutaneous injections of large quantities of fluid for therapeutic purposes.

A subcutaneous injection of fluid in large volume.

Subcutaneous injection of a saline or other solution.

The introduction into the subcutaneous tissues of fluids, especially physiological sodium chloride solution, in large quantity. The most common sites for insertion of the needles for hypodermoclysis are over the sides of the rib cages and the loose tissue in each upper flank. This method of introducing fluids into the body is contraindicated in cases of edema, and it may be complicated by abscess formation, puncture of a large blood vessel, and necrosis and sloughing of the tissues due to poor absorption. The enzyme hyaluronidase may be injected into the tubing at each injection site at the start of clysis, and sometimes an additional 1 ml is added to the solution to facilitate absorption. Called also subcutaneous infusion.
