Comparison of two different concentrations of hyaluronidase in patients receiving one-hour infusions of hypodermoclysis.
The purpose of this randomized, double-blind study was to compare 300 units of hyaluronidase per one-half liter to 150 units per one-half liter in patients receiving brief infusions for subcutaneous hydration. Twenty-five evaluable patients were randomized to receive a local injection of 300 units of hyaluronidase or 150 units of hyaluronidase immediately before two 1-hr infusions of two-thirds dextrose 5% and one-third normal saline solution (500 cc volume). The following day a crossover took place, and patients received the alternate treatment before each of the two 1-hr infusions. The intensity and swelling as reported by the patient (visual analogue scale 0-100), and the intensity of edema and rash as assessed by the investigator (score 0-4) were not significantly different between groups. The patients' and investigators' final choice was also not significantly different. Patients could not distinguish between bolus and their previous experience with overnight clysis. Our results suggest that brief infusions are well tolerated for subcutaneous hydration of patients with advanced cancer. A concentration of 150 units of hyaluronidase per one-half liter is well tolerated in this population.
