Transdermal fentanyl patch for postoperative analgesia in total knee arthroplasty: a randomized double-blind controlled trial.

ABSTRACT: PURPOSE:To assess the efficacy of a transdermal fentanyl patch (TFP) (50 ?g/hour) applied 10-12 hours before surgery versus placebo for postoperative pain control of total knee arthroplasty (TKA). MATERIALS AND METHODS:We enrolled 40 patients undergoing elective TKA under spinal anesthesia using isobaric or hyperbaric bupivacaine. Subjects were randomized to receive a TFP (Duragesic(®) 50 ?g/hour) or placebo patch applied with a self-adhesive to the anterior chest wall 10-12 hours before spinal anesthesia. Every patient was given patient-controlled morphine for postoperative pain control. Patients were evaluated every 4 hours until 48 hours. RESULTS:Morphine consumption at 24 and 48 hours in the TFP group versus the placebo group was 15.40±12.65 and 24.90±20.11 mg versus 33.60±19.06 and 57.80±12.65 mg (P?0.001). Numeric rating scale scores at rest and during movement over 48 hours were lower in the TFP group. Ambulation and nausea/vomiting scores were statistically greater, but not clinically significant in the TFP group. Sedation scores were low and not statistically significantly different between groups. There was no severe respiratory depression. CONCLUSION:TFP (50 ?g/hour) applied 10-12 hours before surgery can effectively and safely decrease morphine consumption and pain scores during the first 48 hours after TKA surgery.

Project description:BackgroundPostoperative pain after total knee arthroplasty (TKA) can cause negative emotions, such as anxiety and depression, which can severely affect a patient's long-term quality of life.ObjectiveThis study aimed to investigate the impact of multimodal analgesia (MMA) on postoperative anxiety and depression following total knee arthroplasty.MethodsThis study included 161 patients who underwent TKA from October 2020 to October 2022 in the First Affiliated Hospital of Wannan Medical College, including 79 cases in the control group and 82 cases in the multimodal analgesia group (MMA). The MMA group were administered acetaminophen 0.5 g/d orally 3 days before the surgery, and an ultrasound-guided fascia iliac compartment block (FICB) with 0.25% ropivacaine 30 ml in the inguinal region ipsilateral to the surgery was performed 1 h before surgery. After the surgery, 100 ml solution includes 100 mg ropivacaine, 2.5 mg morphine, and 0.25 mg epinephrine for intra-articular and periarticular injection. Postoperative conventional intravenous analgesia was used in the control group, including 100 mg ropivacaine, 2.5 mg morphine, and 0.25 mg epinephrine for intra-articular and periarticular injection. Patients were scored for pain, anxiety, and depression in the ward at 3 and 7 days postoperatively, and postoperative patients were scored using telephone callbacks at 3 months postoperatively.ResultsIt was found that the visual analog scale (VAS) scores for pain at rest at 3 days, 7 days, and 3 months postoperatively were significantly lower in the MMA group than in the control group (P < 0.05). The scores for pain with movement were significantly lower in the MMA group than in the control group at 3 days and 7 days postoperatively (P < 0.01), but they were similar at 3 months postoperatively. Compared to the control group, the MMA group had significantly higher American Knee Society scores (AKS) at 3 days, 7 days, and 3 months postoperatively (P < 0.05). Compared to the control group, the MMA group had significantly higher Lower Extremity Functional Scale and Hospital Anxiety and Depression Scale scores (HADS) (P < 0.05) at 3 days and 7 days postoperatively; compared to the control group, the MMA group had a significantly shorter hospital stay (P < 0.01).ConclusionMultimodal analgesia can alleviate postoperative anxiety and depression in the short term, reduce perioperative pain, improve postoperative recovery, and shorten the length of hospital stay.

Project description:BackgroundThe efficacy of intravenous (IV) acetaminophen compared with its oral formulation for postoperative analgesia is unknown. We hypothesized that the addition of acetaminophen to a multimodal analgesia regimen would provide improved pain management in patients after total knee arthroplasty (TKA) and that the effect of acetaminophen would be variable based on the route of delivery.MethodsThe study was a single-center, randomized, double-blinded, placebo-controlled clinical trial on the efficacy of IV vs oral acetaminophen in patients undergoing unilateral TKA. One hundred seventy-four subjects were randomized to one of the 3 groups: IV acetaminophen group (IV group, n = 57) received 1 g IV acetaminophen and oral placebo before postanesthesia care unit (PACU) admission; oral acetaminophen group (PO group, n = 58) received 1 g oral acetaminophen and volume-matched IV normal saline; placebo group (Placebo group, n = 59) received oral placebo and volume-matched IV normal saline. Pain scores were obtained every 15 minutes during PACU stay. Average pain scores, maximum pain score, and pain scores before physical therapy were compared among the 3 groups. Secondary outcomes included total opiate consumption, time to PACU discharge, time to rescue analgesia, and time to breakthrough pain.ResultsThe average PACU pain score was similar in the IV group (0.56 ± 0.99 [mean ± standard deviation]) compared with the PO group (0.67 ± 1.20; P = .84) and Placebo group (0.58 ± 0.99; P = .71). Total opiate consumption at 6 hours (0.47 mg hydromorphone equivalents ± 0.56 vs 0.54 ± 0.53 vs 0.54 ± 0.61; P = .69) and at 24 hours (1.25 ± 1.30 vs 1.49 ± 1.34 vs 1.36 ± 1.31; P = .46) were also similar between the IV, PO, and Placebo groups. No significant differences were found between all groups for any other outcome.ConclusionNeither IV nor oral acetaminophen provides additional analgesia in the immediate postoperative period when administered as an adjunct to multimodal analgesia in patients undergoing TKA in the setting of a spinal anesthetic.
