Study Shows Drinking Water before Knee Surgery Works Better than IV Fluids for Hydration 

 

For Immediate Release
November 9, 2019

Dallas, November 9, 2019 — A presentation at the 2019 AAHKS Annual Meeting reported on a prospective study where researchers sought to determine the optimal way to administer fluids to patients undergoing total knee arthroplasty (TKA). 

During the randomized trial, 130 patients were grouped into those who would drink clear fluids prior to surgery and those who would have intravenous fluids (IVF) administered traditionally. 

Patients in the oral group were instructed to drink a minimum of three, 20-ounce servings of clear fluids every day for three days prior to total knee arthroplasty. They were also instructed to drink 10 ounces of clear fluids four hours before surgery. Then, IVFs were discontinued when the patients started drinking or when the IVFs given reached 500mL. 

Lead author, Jason M. Jennings, MD and co-authors, Mauricio Mejia, MD, Michael A. Williams, MD, Roseann M. Johnson, BS, Charlie C. Yang, MD and Douglas A. Dennis, MD, found that those who had the traditional IVF had an increased body weight (BW) the evening of the surgery and the first two days after the surgery. Those who drank fluids were more hydrated. 

The study concluded that “Oral fluid intake with IVF restriction in the perioperative period after TKA may offer short-term benefits with swelling and BW fluctuations. 

Dr. Jennings received the 2019 James A. Rand Young Investigator’s Award for this work.
