RESUMO
BACKGROUND AND AIMS: The aim of the study is to measure the postoperative adequacy of pain relief and functional recovery after unilateral primary total knee arthroplasty or total knee replacement (TKR) with a multimodal approach. SETTINGS AND DESIGN: This was a retrospective observational study done in a tertiary care center. MATERIALS AND METHODS: Eighty patients aged 18-65 years (yrs) with ASA Physical Status Classes I, II, and III operated for unilateral primary TKR surgery under suitable Anaesthesia and was administered ultrasound-guided adductor canal block + periarticular infiltration (PI) from January 2018 to January 2019 were included. Thereafter, the patients visual analog scale (VAS) scores at rest, 45° knee flexion, and mobilization as well as additional analgesia given were noted after going through the records at following time points: 12 hourly for 24 h and thereafter on postoperative day 1 (POD1) and POD2. Level of block, adverse events, and functional recovery (time up and go [TUG] test, 10 s walk test) on POD1 and POD2 were also noted. STATISTICAL ANALYSIS AND RESULTS: The statistical software namely SPSS 18.0 were used for the analysis of the data. The mean VAS score at 12 h was 4.33 ± 1.3 which worsened at 24 h with steady improvement over the next 2 days. Similarly, the case with a mean VAS score at 45° flexion and on mobilization showed a similar trend. At 12 h postadductor block, besides intravenous (i.v.) paracetamol, 32.6% of patients were given tramadol 50 mg i.v. whereas one patient was given a buprenorphine patch in addition to tramadol. The number of patients requiring additional tramadol and buprenorphine patch steadily increased over the next 2 days. The average time taken for the TUG test at 24 h was 30.98 ± 4.77 s, and the average time taken for the 10 s walk test at 24 h was 6.16 ± 1.10 steps with improvement in performance over the next 2 days. CONCLUSION: In our study, our multimodal analgesia model did not provide satisfactory analgesia though mobilization was not hampered.
RESUMO
BACKGROUND AND AIM: The present study was carried out to compare the efficacy of continuous epidural infusion of two amide local anesthetics, ropivacaine and bupivacaine with fentanyl for postoperative analgesia in major abdominal surgeries. MATERIAL AND METHODS: A total of 60 patients scheduled for major abdominal surgery were randomized into two study Groups B and R with thirty patients in each group. All patients were administered general anesthesia after placing epidural catheter. Patients received continuous epidural infusion of either 0.25% bupivacaine with 1 ug/ml fentanyl (Group B) or of 0.25% ropivacaine with 1 ug/ml fentanyl (Group R) at the rate 6 ml/h intraoperatively. Postoperatively, they received 0.125% bupivacaine with 1 ug/ml fentanyl (Group B) or 0.125% ropivacaine with 1 ug/ml fentanyl (Group R) at the rate 6 ml/h. Hemodynamic parameters, visual analog scale (VAS), level of sensory block, and degree of motor block (based on Bromage scale) were monitored for 24 h postoperatively. RESULTS: Hemodynamic parameters and VAS scores were comparable in the two groups. The level of sensory block was higher in bupivacaine group. There were more patients with higher Bromage score in the (23.3%) bupivacaine group than in (6.7%) ropivacaine group though the difference was not statistically significant. CONCLUSION: Both ropivacaine and bupivacaine in the concentration of 0.125% with fentanyl 1 ug/ml are equally safe, with minimal motor block and are effective in providing postoperative analgesia.
