Effect of Oral Carbohydrate Solution Administered Before Hip Arthroplasty on Preoperative Anxiety and Postoperative Patient Comfort: A Randomized Controlled Trial

Published:February 16, 2023DOI:



      This study aimed to determine the effect of oral carbohydrate solution (OCS) administered before hip arthroplasty (HA) on preoperative anxiety and postoperative patient comfort.


      The study was a randomized controlled clinical trial.


      Fifty patients undergoing HA were randomized into two groups: The intervention group (n = 25) received OCS before surgery, and the control group (n = 25) fasted from midnight till surgery. The patients' preoperative anxiety was assessed using the State-Trait Anxiety Inventory (STAI), symptoms affecting postoperative patient comfort parameters using the Visual Analog Scale (VAS), and comfort levels specific to HA surgery using the Post-Hip Replacement Comfort Scale (PHRCS). Pre- and post-operative blood glucose levels of the patients were measured.


      In intragroup and intergroup assessments, the decrease in the preoperative and postoperative anxiety, pain, thirst, hunger, and nausea/vomiting levels were statistically significant (P < .05) in the OCS group. The OCS group's comfort levels specific to hip replacement were higher than those of the control group (P ≤ .001). In the intergroup and intragroup assessment of the patients' blood glucose levels, there was a statistically significant difference in favor of the OCS group (P < .05).


      The results of this study provide evidence supporting OCS administration before HA surgery.
