Continuous Femoral Nerve Block

Objectives: This study aims to investigate the clinical effect of dexmedetomidine (DEX) combined with low concentrations of ropivacaine in ultrasound-guided continuous fem­oral nerve block for postoperative analgesia in elderly patients with total knee arthroplasty (TKA). Materials and Methods: Patients were divided into three groups: group C, group D1, and group D2. For postoperative analgesia, patients in group C were given 0.15% ropivacaine, patients in group D1 were given 0.15% ropivacaine + 0.02 μg × kg–1 × h–1 DEX, and patients in group D2 were given 0.15% ropivacaine + 0.05 μg × kg–1 × h–1 DEX. The visual analogue scores in the resting state, active state (AVAS), and passive functional exercise state (PVAS), degree of joint bending, and Ramsay scores were recorded. Results: The Ramsay scores were significantly higher, AVAS scores were significantly lower, PVAS scores were significantly decreased, the degree of joint bending was significantly higher, and the time to the first postoperative ambulation was shorter in groups D1 and D2 than group C. Furthermore, the time to the first postoperative ambulation was shorter in group D2 than in group D1, patients in groups D1 and D2 were more satisfied than patients in group C, and patients in group D2 were more satisfied than patients in group D1. Conclusion: The protocol of 0.05 μg × kg–1 × h–1 of DEX combined with 0.15% ro­pivacaine in ultrasound-guided continuous femoral nerve block for postoperative analgesia in elderly patients with TKA provides a better analgesic effect than without DEX performance.

Background: Effective pain control in Total knee arthroplasty (TKA) is important for optimizing the rehabilitation process in order to achieve patient satisfaction with a good functional outcome as well as reduce hospitalization duration and costs. Combined use of aesthetic with tramadol has been reported to achieve a longer duration of sensory and motor block. The aim of this study is to evaluate the quality and duration of postoperative analgesia produced by ultrasound guided femoral nerve block (FNB) by bupivacaine versus (bupivacaine & tramadol) in patients undergoing total knee arthroplasty under spinal anesthesia. Methods: This prospective randomized controlled double blinded study was carried out on 60 patients aged above 50 years; American Society of Anesthesiologists physical status (ASA) I-III scheduled for total knee arthroplasty under spinal anesthesia. Patients were randomized to one of two equal groups: Group I control (C): received FNB with 30 ml 0.25% bupivacaine. Group II tramadol (T): received FNB with 30ml 0.25% bupivacaine and 100 mg tramadol. Results: Postoperative heart rate was significantly increased in group C than group T at 8h, 12h, 16h and 24h. Postoperative mean arterial blood pressure was significantly increased in group C than group T at 6h, 8h, 12h, 16h and 24h. There were 30 (100%) patients required rescue analgesia in group C and 19 (63.33%) patients in group T which was increased significantly in group C than group T. The time to first analgesic requirement was significantly decreased in group C than group T. Total morphine consumption was increased significantly in group C than group T. VAS was increased significantly in group C than group T at 6, 8, 12, 16 and 24 hours. Adverse effects were insignificantly different between both groups. Conclusion: Adding tramadol (100 mg) to 0.25% bupivacaine (to a volume of 30 ml) during US guided FNB of TKA under spinal anesthesia was associated with better postoperative analgesia when compared with 0.25% bupivacaine alone.

Background & Objective: Local infiltration of knee joints during knee joint surgery has been used for postoperative analgesia with preservation of motor function of quadriceps muscle, which helps in early mobilization. Femoral nerve block has been incriminated with paralyses of vastus medialis muscle. We aimed to compare postoperative analgesia between femoral nerve block and local infiltration in patients undergoing unilateral total knee arthroplasty (TKA).Methodology: After obtaining institutional ethical approval and written informed consent from the patients, this randomized controlled trial was conducted at Department of Anesthesia at Teerthankar Mahaveer Medical College & Research Centre between July - December 2018. The study was conducted on 60 patients of ASA I and II, undergoing unilateral total TKA. Patients were randomly divided into two groups: Group FB patients underwent femoral nerve block, and Group LI patients underwent local infiltration analgesia. Sedation score, numeric rating scale, motor power and frequency of nausea/vomiting were recorded and statistical analysis done.Results: We observed better pain relief in patients which received femoral nerve block as compared to local infiltration analgesia (p < 0.001). Sedation score was higher in Group LI and was statistically significant between the two groups at 4th, 12th, and 48th hour (p < 0.05). Group FB patients were associated with higher muscle power grades (p < 0.001) as compared to local infiltration analgesia patients. Fentanyl demand was observed to be lesser in Group FB as compared to Group LI (p < 0.001).Conclusion: The study concludes that femoral nerve block produces better pain reliefin patients posted for unilateral knee arthroplasty as compared to local infiltration ofthe local anesthetic solution. However, there is gross reduction in range of motion withfemoral nerve block.Citation: Varshney RK, Prasad MK, Garg M.

Abstract Background: The authors conducted a randomized, controlled, parallel-arm, superiority study to test the hypothesis that a continuous adductor canal block decreases the time to attain four discharge criteria compared with a continuous femoral nerve block after tricompartment knee arthroplasty. Methods: Subjects undergoing tricompartment knee arthroplasty were randomized using computer-generated lists to either an adductor canal or femoral perineural catheter (3-day ropivacaine 0.2% infusion) in an unmasked manner. The primary outcome was the time to attain four criteria: (1) adequate analgesia; (2) intravenous opioids independence; (3) ability to stand, walk 3 m, return, and sit down; and (4) ambulate 30 m. Results: Subjects with an adductor canal catheter (n = 39) reached all four criteria in a median of 55 h (interquartile, 42 to 63 h) compared with 61 h (49 to 69 h) for those with a femoral catheter (n = 41; 95% CI, −13 to 1 h; P = 0.12). The percentage of subjects who reached the two mobilization criteria on postoperative days 1 and 2 were 72 and 95% for those with an adductor canal catheter (n = 39), but only 27 and 76% in subjects with a femoral catheter (n = 41; both P &lt; 0.001). Differences in pain scores at rest and intravenous opioid requirements were minimal, but femoral infusion improved dynamic analgesia (P = 0.01 to 0.02). Conclusion: Compared with a continuous femoral nerve block, a continuous adductor canal block did not appreciably decrease the time to overall discharge readiness even though it did decrease the time until adequate mobilization, primarily because both groups experienced similar analgesia and intravenous opioid requirements that—in most cases—exceeded the time to mobilization.
