Abstract
BACKGROUND: Optimal perioperative fluid management has not been established in patients undergoing orthopedic surgical procedures. Our purpose was to investigate the effects of perioperative fluid management (ie, preoperative, intraoperative, and postoperative) on patients undergoing total knee arthroplasty (TKA). METHODS:One hundred thirty patients who met inclusion criteria undergoing primary unilateral TKA were prospectively randomized into traditional (TFG) vs oral (OFG) perioperative fluid management groups. The primary outcome was change in body weight (BW). Secondary outcome measures included knee motion, leg girth, bioelectrical impendence, quadriceps activation, functional outcomes testing, Knee injury and Osteoarthritis Outcome Score JR, VR-12, laboratory values, vital signs, patient satisfaction, pain scores, and adverse events. RESULTS: The TFG had increased BW the evening of surgery (7.0 ± 4.3 vs 3.0 ± 3.9, P < .0001), postoperative day (POD) #1 (9.1 ± 4.3 vs 4.7 ± 3.9, P < .0001), and POD #2 (6.2 ± 5.0 vs 4.4 ± 4.0, P = .032). Bioelectrical impedance showed less limb edema in the OFG (4.2 ± 29.7 vs 17.8 ± 30.3, P < .0001) on POD #1. Urine specific gravity differences were seen preoperatively between groups (OFG, more hydrated, P = .002). Systolic blood pressure decrease from the baseline was greater in the OFG on arrival to the floor (19.4 ± 13.5 vs 10.6 ± 12.8, P < .0001) and 8 (23.4 ± 13.3 vs 17.0 ± 12.9, P = .006) and 16 (25.8 ± 13.8 vs 25.8 ± 13.8, P = .046) hours after floor arrival. The TFG had more urine output on POD #1 (3369 mL ± 1343 mL vs 2435 mL ± 1151 mL, P < .0001). The OFG were more likely to go home on POD #1 than the TFG (63 vs 56, P = .02). CONCLUSION: Oral fluid intake with IVF restriction in the perioperative period after TKA may offer short-term benefits with swelling and BW fluctuations. The authors continue to limit perioperative IVFs and encourage patient initiated fluid intake.
