The Effect of Cold Application on Pain Level, Edema and Drainage Amount

The Effect of Cold Application on Pain Level, Edema and Drainage Amount in Patients With Total Knee Arthroplasty: A Randomized Controlled Study

In this study, we aimed to investigate the effect of cold application applied for 20 minutes every hour for 8 hours on the first day, second and third days after total hip arthroplasty with gel pads, on the pain level, edema and drainage amount of total hip arthroplasty patients. The main question[s]it aims to answer are:

• Is there a difference between the pain levels of patients in the control and cold application arms?
• Is there a difference between the knee edema of patients in the control and cold application arms?
• Is there a difference between the amount of drainage of patients in the control and cold application arms? This study was planned as a prospective, parallel, two-arm (1:1) randomized controlled trial (RCT).

• When the patient arrives at the service after TKA, cold application will begin with gel pads at 0 ºC and continue for eight hours. After TKA, cold application will continue for 20 minutes every hour between 08.00-16.00 on the 1st and 2nd day.
• After TKA, pain intensity will be evaluated and at the 6th, 24th and 48th hours.
• Knee circumference measurements for knee edema will be made before TKA and at the 24th and 48th hours after TKA.
• After being taken to bed after TKA, the amount of drainage will be measured at the 1st, 6th and 24th hours.
• In the first 24 hours and 24-48 hours after TKA. Analgesic consumption between hours will be recorded.
• Knee temperature will be measured before and after each cold application.
• Knee temperature will be measured before and after each cold application. Measurements of the control group will be made at the specified times in the cold application group. Cold application will not be applied to the control group.
