Project description:BackgroundPostoperative inflammation following total hip arthroplasty (THA) can lead to delayed mobilization and return of hip function. Our primary aim was to assess whether local infiltration analgesia (LIA) during surgery can prevent postoperative inflammation.MethodsThis is a sub-analysis of data from a broader double-blind study where 56 patients received spinal anaesthesia for THA. Additionally, Group FNB (Femoral Nerve Block) received an ultrasound-guided femoral nerve block using 30 mL of ropivacaine 7.5 mg/mL (225 mg), and 151.5 mL of saline peri-articularly intra-operatively. Group LIA received 30 mL saline in the femoral nerve block and ropivacaine 2 mg/mL, 300 mg (150 mL) + ketorolac 30 mg (1 mL) + adrenaline 0.5 mg (0.5 mL) peri-articularly. After 23 h, the LIA mixture (22 mL) was injected via a catheter placed peri-articularly in Group LIA and 22 mL saline in Group FNB. A battery of pro- and anti-inflammatory cytokines was assessed using a commercially available kit preoperatively and after 4 h and 3 days postoperatively. Additionally, CRP, platelet count and white blood count was determined pre- and postoperatively.ResultsThere was a general trend towards an increase in pro-inflammatory cytokines postoperatively, which returned to normal levels after 3 days. IL-6 concentration was significantly lower 4 h postoperatively in Group LIA compared to Group FNB (p = 0.015). No other significant differences were found between the groups in other cytokines. CRP levels were significantly higher in Group FNB compared to Group LIA 3 days postoperatively (p < 0.001). No other significant differences were seen between the groups.ConclusionLocal infiltration analgesia has a modest but short-lasting effect on postoperative inflammation in patients undergoing total hip arthroplasty. This is likely to be due to local infiltration of ketorolac and/or local anaesthetics in the LIA mixture. Future studies should be directed towards assessing whether the use of LIA translates into better patient outcomes.Trial registrationEudraCT Number 2012-003875-20 . Registered 3 December 2012.

Project description:Local infiltration analgesia (LIA) is commonly used for postoperative pain management following total hip arthroplasty (THA). However, the long-term effects of the component drugs are unclear. The aim of our study was to investigate functional outcome, quality of life, chronic post-surgical pain, and adverse events in patients within 2 years of undergoing THA.The study was a secondary analysis of data from a previous larger study. Eighty patients were randomized to receive either intrathecal morphine (Group ITM) or local infiltration analgesia (Group LIA) for pain management in a double-blind study. The parameters measured were patient-assessed functional outcome [using the Hip dysfunction and Osteo-arthritis Outcome Score (HOOS) questionnaire], health-related quality of life [using the European Quality of Life-5 dimensions (EQ-5D) questionnaire and the 36-Item Short Form Health Survey (SF-36) score], and pain using the numeric rating score (NRS), with persistent post-surgical pain having a NRS of > 3 or a HOOS pain sub-score of > 30. All complications and adverse events were investigated during the first 2 years after primary surgery.Pain intensity and rescue analgesic consumption were similar between the groups after hospital discharge. No differences were found in HOOS or SF-36 score between the groups up to 6 months after surgery. A significant group × time interaction was seen in the EQ 5D form in favor of the LIA group. No between-group difference in persistent post-surgical pain was found at 3 or 6 months, or in adverse events up to 2 years after surgery.Analysis of functional outcome, quality of life, and post-discharge surgical pain did not reveal significant differences between patients receiving LIA and those receiving ITM. LIA was found to be a safe technique for THA during the long-term follow-up. However, it should be noted that these conclusions are based on a limited number of patients.

Project description:The local infiltration analgesia (LIA) technique has been widely used to reduce opioid requirements and to improve postoperative mobilization following total hip arthroplasty (THA). However, the evidence for the efficacy of LIA in THA is not yet clear. We determined whether single-shot LIA in addition to a multimodal analgesic regimen would reduce acute postoperative pain and opioid requirements after THA.116 patients undergoing primary THA under spinal anesthesia were included in this randomized, double-blind, placebo-controlled trial. All patients received oral opioid-sparing multimodal analgesia: etoricoxib, acetaminophen, and glucocorticoid. The patients were randomized to receive either 150 mL ropivacaine (2 mg/mL) and 0.5 mL epinephrine (1 mg/mL) or 150 mL 0.9% saline. Rescue analgesic consisted of morphine and oxycodone as needed. The primary endpoint was pain during mobilization in the recovery unit. Secondary endpoints were pain during mobilization on the day after surgery and total postoperative opioid requirements on the first postoperative day.The levels of pain during mobilization-both in the recovery unit and on the day after surgery-and consumption of opioids on the first postoperative day were similar in the 2 groups.LIA did not provide any extra analgesic effect after THA over and above that from the multimodal analgesic regimen used in this study.

Project description:Background and purposeThe effect of postoperative intra-articular bolus injections after total hip arthroplasty (THA) remains unclear. We tested the hypothesis that intra-articular bolus injections administered every 6 hours after surgery during the first 24 hours would significantly improve analgesia after THA.Patients and methods80 patients undergoing THA received high-volume local infiltration analgesia (LIA; 200 mg ropivacaine and 30 mg ketorolac) followed by 4 intra-articular injections with either ropivacaine (100 mg) and ketorolac (15 mg) (the treatment group) or saline (the control group). The intra-articular injections were combined with 4 intravenous injections of either saline (treatment group) or 15 mg ketorolac (control group). All patients received morphine as patient-controlled analgesia (PCA). The primary outcome was consumption of intravenous morphine PCA and secondary outcomes were consumption of oral morphine, pain intensity, side effects, readiness for hospital discharge, length of hospital stay, and postoperative consumption of analgesics at 3, 6, and 12 weeks after surgery.ResultsThere were no statistically significant differences between the 2 groups regarding postoperative consumption of intravenous morphine PCA. Postoperative pain scores during walking were higher in the treatment group from 24-72 hours after surgery, but other pain scores were similar between groups. Time to readiness for hospital discharge was longer in the treatment group. Other secondary outcomes were similar between groups.InterpretationPostoperative intra-articular bolus injections of ropivacaine and ketorolac cannot be recommended as analgesic method after THA.

Project description:Postoperative pain is often severe after total knee arthroplasty (TKA). We investigated the efficacy of the local infiltration analgesia (LIA) technique, both intraoperatively and postoperatively.48 patients undergoing TKA were randomized into 2 groups in a double-blind study. In group A, 400 mg ropivacaine, 30 mg ketorolac, and 0.5 mg epinephrine were infiltrated periarticularly during operation. In group P, no injections were given. 21 h postoperatively, 200 mg ropivacaine, 30 mg ketorolac, and 0.1 mg epinephrine were injected intraarticularly in group A, and the same volume of saline was injected in group P. All patients were followed up for 3 months.Median morphine consumption was lower in group A during the first 48 h: 18 (1-74) mg vs. 87 (36-160) mg in group P. Postoperative pain was lower at rest in group A during the first 27 h, and on movement during the first 48 h, except at 21 h. Time to fulfillment of discharge criteria was shorter in group A than in group P: 3 (1-7) vs. 5 (2-8) days. Patient satisfaction was higher in group A than in group P on days 1 and 7. The unbound venous blood concentration of ropivacaine was below systemic toxic blood concentrations.The local infiltration analgesia (LIA) technique provides excellent pain relief and lower morphine consumption following TKA, resulting in shorter time to home readiness and higher patient satisfaction. There were few side effects and systemic LA concentrations were low.

Project description:BackgroundThere have been few studies describing wound infiltration with additional intraarticular administration of multimodal analgesia for total knee arthroplasty (TKA). In this study, we assessed the efficacy of wound infiltration combined with intraarticular regional analgesia with epidural infusion on analgesic requirements and postoperative pain after TKA.Methods40 consecutive patients undergoing elective, primary TKA were randomized into 2 groups to receive either (1) intraoperative wound infiltration with 150 mL ropivacaine (2 mg/mL), 1 mL ketorolac (30 mg/mL), and 0.5 mL epinephrine (1 mg/mL) (total volume 152 mL) combined with intraarticular infusion (4 mL/h) of 190 mL ropivacaine (2 mg/mL) plus 2 mL ketorolac (30 mg/mL) (group A), or (2) epidural infusion (4 mL/h) of 192 mL ropivacaine (2 mg/mL) combined with 6 intravenous administrations of 0.5 mL ketorolac (30 mg/mL) for 48 h postoperatively (group E). For rescue analgesia, intravenous patient-controlled-analgesia (PCA) morphine was used. Morphine consumption, intensity of knee pain (0–100 mm visual analog scale), and side effects were recorded. Length of stay and corrected length of stay were also recorded (the day-patients fulfilled discharge criteria).ResultsThe median cumulated morphine consumption, pain scores at rest, and pain scores during mobilization were reduced in group A compared to group E. Corrected length of stay was reduced by 25% in group A compared to group E.InterpretationPeri- and intraarticular analgesia with multimodal drugs provided superior pain relief and reduced morphine consumption compared with continuous epidural infusion with ropivacaine combined with intravenous ketorolac after TKA.

Project description:Background Total knee replacement is often associated with significant postoperative pain. Although the use of a femoral nerve block is well-established, local infiltration analgesia has gained popularity in recent years. We compared single-shot local infiltration analgesia with a single-shot femoral nerve block for patients undergoing primary total knee arthroplasty. Methods A total of 194 patients were randomised to receive either local infiltration analgesia (150 ml bupivacaine 0.067% with adrenaline) or a femoral nerve block (20 ml 0.375% levobupivacaine). Both groups received spinal anaesthesia. The primary outcome measure was the total morphine consumption. Secondary outcome measures included: post-operative pain scores, rehabilitation goals, readiness for discharge, and physical, mental, and functional outcomes, including the Oxford Knee Score (OKS). Results A total of 69 patients in the local infiltration analgesia group and 79 patients in the femoral nerve block group were analysed. Median total morphine consumption was significantly greater in the local infiltration analgesia group as compared to the femoral nerve block group (54.67 mg vs 45 mg, respectively, p=0.0388). The post-operative OKS at six weeks was slightly more improved for the femoral nerve block group than for local infiltration analgesia (12.5 vs 9 point median improvements for the femoral nerve block and local infiltration analgesia groups, respectively, p=0.0261). There were no statistically significant differences in other secondary outcome measures. Conclusion A single-shot femoral nerve block significantly reduces the opioid requirement for primary total knee arthroplasty but is otherwise comparable to single-shot local infiltration analgesia.

Project description:Opioids have been widely used in the USA for pain control after total knee arthroplasty (TKA). However, adverse effects, especially the possibility of addiction, have increased interest in opioid-free pain management after surgery. We therefore sought to review current pain management protocols after TKA, focusing especially on opioid-free alternatives. We reviewed the literature on pain management after TKA using Medline (PubMed), through June 30, 2018, using the keywords "TKA" and "analgesia." We found 388 articles but chose to analyze the 34 that presented high-quality (levels I and II) evidence. Local infiltration analgesia (LIA) is a good option for reducing the use of post-operative opioids; many reports have compared LIA against a nerve block or studied the synergies between two protocols of loco-regional anesthesia. Multimodal blood-loss prevention is sometimes recommended in combination with opioid-free analgesia. In most studies, however, no differences are reported or contradictory results exist. Post-operative pain management protocols vary so much that it is difficult to strongly favor a determined pathway.

Project description:BackgroundA superior analgesic method in perioperative pain-management of patients receiving total knee arthroplasty is the subject of controversial debate. Although higher cost-efficiency is claimed for the local infiltration analgesia (LIA), there is a lack of data on its costs compared to peripheral nerve block anaesthesia (PNBA). The goal of this study was to investigate the differences in immediate perioperative costs between the LIA and PNBA in treatment of patients receiving total knee arthroplasty.MethodsThe comparison was conducted based on a randomized controlled clinical trial examining 40 patients with elective, primary total knee arthroplasty (TKA, 20 patients with LIA and 20 patients with PNBA). The analysis included surgical case costs, anaesthesiological case costs, material, costs of postoperative opioid requirements and catheter review visits for patients receiving PNBA.ResultsThe overall mean costs for the LIA-group were 4328.72€ and 4368.12€ for the PNBA (p = 0.851). While there was no statistically significant difference in surgical case costs, the anaesthesiological costs were lower with the LIA procedure (1370.26€ vs. 1542.45€, p = 0.048). Material costs in the LIA group were 4.18€/patient and 94.64€/patient with the PNBA. Costs for postoperative opioid requirements showed no statistically significant difference between the two procedures.ConclusionsThere is no relevant difference in immediate perioperative costs between LIA and PNBA. Shorter induction times lead to lower anaesthesiological case costs with the LIA. Overall economic aspects seem to play a less important role for determining an adequate procedure for perioperative pain management.Trial registrationThe study was approved by the ethics-review-board of Charité Hospital Berlin (Ethikausschuss 4, Charité - Universitätsmedizin Berlin, on 16th February 2017) and registered with data safety authorities. Study patients provided written informed consent to participate in the trial. Study registry: ClinicalTrials.gov, NCT03114306 .

Project description:BACKGROUND:We implemented local infiltration analgesia (LIA) as a technique of providing post-operative pain management and early mobilization after arthroplasty surgery and have progressively found patients able to go home earlier. This study compares the national data on hip and knee arthroplasty provided by the Royal Australasian College of Surgeons and Medibank Private with our outcomes using LIA and rapid recovery. METHODS:Prospective study of one surgeon including 200 knees, and 165 hips in the two years till June 2016. Variables included in comparison to the two groups were: length of stay, percentage of patients transferred to rehabilitation or intensive care unit (ICU), readmitted within 30?days and average separation cost. RESULTS:Hip replacement median length of stay in our series was two nights versus five nights, inpatient rehabilitation 7% versus 36%, ICU admission zero versus 4%, and readmissions 3.9% versus 6.0%, the average hospital separation cost in our series was $17?813 versus $26?734. Knee replacement median length of stay in our study was one night versus five nights, ICU 0.5% versus 3%, rehabilitation 4.5% versus 43%, and readmission 6% versus 7%, the average hospital separation cost in our group was $16?437 versus $27?505. CONCLUSION:The comprehensive approach of LIA and rapid recovery enables patients to have shorter hospitalization, lower rehabilitation incidence and a resultant reduction in health expenditure.
