RESUMO

OBJECTIVE: To investigate use of a candidate maxillary nerve block in rabbits. ANIMALS: 13 healthy New Zealand White rabbits (Oryctolagus cuniculus). PROCEDURES: In phase 1, the maxillary nerve block procedure was performed in 7 sedated rabbits with 2 volumes (0.25 and 0.5 mL) of a saline (0.9% NaCl)-tissue marker dye solution (1 injection/side by random assignment). Rabbits were euthanized and dissected; numeric scales were used to rate injection accuracy and extent of staining. In phase 2, the nerve block was performed with articaine hydrochloride-epinephrine solution (0.5 mL) on a randomly assigned side in 6 sedated rabbits, with the contralateral side used as a control. Sensory function of the relevant dermatome was tested in triplicate with an algesiometer 0, 30, and 90 minutes after recovery from sedation. Statistical methods were used to compare results between injection volumes (phase 1) and between treated and control sides (phase 2). RESULTS: In phase 1, dye was in contact with the targeted nerve after 13 of 14 injections. Accuracy and extent of staining did not differ significantly between volumes. In phase 2, algesiometer-applied force tolerance differed significantly between treated and control sides 30 minutes after recovery from sedation (56 to 145 minutes after the nerve block procedure). No adverse effects were detected in either study phase. CONCLUSIONS AND CLINICAL RELEVANCE: The described technique for a maxillary nerve block was accurate and effective for desensitization of the relevant dermatome as assessed by algesiometry in healthy rabbits. Additional studies are needed to assess use of this procedure in rabbits of other breeds and its efficacy for clinical use. (Am J Vet Res 2020;81:843-848).

RESUMO

BACKGROUND: Total knee arthroplasty is accompanied by moderate to severe postoperative pain. Postoperative pain hampers the functional recovery and lowers patient satisfaction with the surgery. Recently, the adductor canal block (ACB) has been widely used in total knee arthroplasty. However, there is no definite answer as to the location of a continuous block within the ACBs. METHOD: Randomized controlled trials about relevant studies were searched in PubMed (1996 to Oct 2019), Embase (1996 to Oct 2019), and Cochrane Library (CENTRAL, Oct 2019). RESULTS: Five studies involving 348 patients met the inclusion criteria. Pooled data indicated that the proximal ACB was as effective as the distal ACB in terms of total opioid consumption (P = .54), average visual analog scale (VAS) score (P = .35), worst VAS score (P = .19), block success rate (P = .86), and time of catheter insertion (P = .54). CONCLUSIONS: Compared with the distal ACB, the proximal ACB showed similar analgesic efficacy for total opioid consumption, average VAS score, worst VAS score, block success rate, and time of catheter insertion. However, because of the limited number of involved studies, more high-quality studies are needed to further identify the optimal location of the ACB.

RESUMO

BACKGROUND: Adductor canal block (ACB) has emerged as an attractive alternative for femoral nerve blocks (FNB) as the peripheral nerve block of choice for total knee arthroplasty (TKA), preserving quadriceps motor function while providing analgesia comparable to FNB. However, its optimal application for TKA remains controversial. The objective of this meta-analysis was to compare continuous-injection ACB (CACB) vs single-injection ACB (SACB) for postoperative pain control in patients undergoing TKA. METHODS: This study attempts to identify the available and relevant randomized controlled trials (RCTs) regarding the analgesic effects of CACB compared to SACB in patients undergoing TKA according to electronic databases, including PubMed, Medline, Web of Science, EMbase, and the Cochrane Library, up to September 2019. Primary outcomes in this regard included the use of a visual analogue scale (VAS) pain score with rest or activity, while secondary outcomes were cumulative opioid consumption, length of hospital stay (LOS), complications of vomiting and nausea, and rescue analgesia. The corresponding data were analyzed using RevMan v5.3. ETHICAL REVIEW: Because all of the data used in this systematic review and meta-analysis has been published, the ethical approval was not necessary RESULTS:: This research included 9 studies comprised of 739 patients. The analyzed outcomes demonstrated that patients who received CACB had a better at rest-VAS scores at 4 hours (P = .007), 8 hors (P < .0001), 12 hours (P < .0001), 24 hours (P = .02), mobilization-VAS score at 48 hours (P < .0001), and rescue analgesia (P = .03) than those who underwent SACB. Nevertheless, no significant differences were present between the 2 strategies in terms of pain VAS scores 48 hours at rest (P = .23) and 24 hours at mobilization (P = .10), complications of vomiting and nausea (P = .42), and length of hospital stay (P = .09). CONCLUSION: This meta-analysis indicated that CACB is superior to SACB in regard to analgesic effect following TKA. However, due to the variation of the included studies, no firm conclusions can be drawn. Further investigations into RCT are required for verification.

RESUMO

OBJECTIVE: To evaluate the analgesic efficacy and safety of paravertebral block (PVB) versus intercostal nerve block (INB) in thoracic surgery and breast surgery. METHODS: The PubMed, Web of Science, Embase and the Cochrane Library were searched up to February 2020 for all available randomized controlled trials (RCTs) that evaluated the analgesic efficacy and safety of PVB compared with INB after thoracic surgery and breast surgery. For binary variables, odds ratio (OR) and 95% confidence interval (CI) was used. For continuous variables, weighted mean difference (WMD) and 95% confidence interval (CI) were used. RevMan5. 3 and Stata/MP 14.0 were used for performing the meta-analysis. RESULTS: A total of 9 trials including 440 patients (PVB block:222 patients; INB: 218 patients) met the inclusion criteria. In the primary outcome, there was no significant differences between the two groups with respect to postoperative visual analogue scale (VAS) at 1h (Std. MD = -0. 20; 95% CI = -1. 11to 0. 71; P = 0. 66), 2h (Std. MD = -0. 71; 95% CI = -2. 32to 0. 91; P = 0. 39), 24h (Std. MD = -0. 36; 95% CI = -0. 73 to -0. 00; P = 0. 05) and 48h (Std. MD = -0. 04; 95% CI = -0. 20 to 0. 11; P = 0. 57). However, there was significant difference in VAS of non Chinese subgroup at 1h (Std. MD = 0. 33; 95% CI = 0. 25to 0. 41; P<0. 00001) and VAS of Chinese subgroup at 24h (Std. MD = -0.32; 95% CI = -0.49 to-0.14; P = 0.0003). In the secondary outcome, the analysis also showed no significant difference between the groups according to the rates of postoperative nausea and vomit (OR = 0. 63; 95% CI = 0. 38 to 1. 03; P = 0. 06) and the rates of postoperative additional analgesia (OR = 0. 57; 95% CI = 0. 21 to 1. 55; P = 0. 27). There was significant difference in postoperative consumption of morphine (Std. MD = -14. 57; 95% CI = -26. 63 to -0.25; P = 0. 02). CONCLUSION: Compared with INB, PVB can provide better analgesia efficacy and cause lower consumption of morphine after thoracic surgery and breast surgery.

RESUMO

PURPOSE OF REVIEW: Despite peripheral nerve blockade offering analgesic benefits and improving patient satisfaction, it has not been well adopted in ambulatory anesthesia. In this review, we aim to summarize the evidence underlying peripheral nerve blockade, local anesthetic adjuncts, continuous peripheral nerve blockade and novel analgesic modalities, with the objective to provide recommendations on postoperative analgesia optimization after peripheral nerve blockade in an ambulatory setting. RECENT FINDINGS: Barriers to the widespread use of peripheral nerve blockade in ambulatory anesthesia could include lack of education and training, and increased anesthetic induction time. Strategies that have demonstrated promise to increase duration of action and attenuate rebound pain phenomenon after peripheral nerve blockade include multimodal analgesia, local anesthetic adjuncts and continuous infusion of local anesthetic. Dexamethasone has been demonstrated to be the most effective local anesthetic adjunct. Continuous peripheral nerve blockade is a reasonable alternative but at the expense of additional costs and logistical reorganization. There is currently insufficient data to promote the ambulatory use of liposomal bupivacaine, cryoanalgesia and percutaneous peripheral nerve stimulation. SUMMARY: Educational programs and parallel processing may promote peripheral nerve blockade in an ambulatory setting, improving the patient experience in the postoperative period. Intravenous dexamethasone should be considered wherever appropriate as part of a multimodal analgesic strategy to optimize postoperative pain control.

RESUMO

The femoral nerve blockage is a procedure that aims to provide anesthesia to the hip, anterior thigh, and stifle. This procedure presents several challenges when performed in veterinary patients with diverse anatomy and physiology. Successful use of this technique will improve a dog's recovery time after surgery in comparison to the commonly used epidural block. A mixed reality application to guide practitioners in the femoral nerve block procedure was developed in Unity and Visual Studio. A 3D model for use within the application was created from pictures of a cadaver leg using photogrammetry software. The Microsoft HoloLens headset provides the mixed reality hardware platform. This paper presents the workflow used in developing the mixed reality application and custom 3D model, as well as initial results with respect to the utility of the application in guiding an anesthesiologist in the procedure of the femoral nerve block.

RESUMO

BACKGROUND: The randomized controlled study aimed to examine the efficacy of preoperative ultrasound-guided erector spinae plane (ESP) block combined with ropivacaine in patients undergoing hepatectomy. METHODS: A total of 60 patients were randomized to ESP block group receiving ropivacaine (Group A) and control group (Group B), n = 30 per group. Visual analog scale (VAS) was recorded in both the groups during rest and movement at the various time intervals. Both the groups were also compared for time to initial anal exhaust, analgesic usage, early postoperative complications and side-effects, walk distance after the operation, time to out-of-bed activity, and duration of hospital stay. RESULTS: No significant differences were observed in the demographic characteristics. For group A, when compared to group B, VAS scores during rest and movement within post-operative 24 hours were decreased, the time of first anus exhaust and ambulation were earlier, analgesic consumption and the incidence of postoperative nausea, vomiting and headache was reduced, the duration of hospital stay were shorter with longer walk distance. CONCLUSION: ESP block combined with ropivacaine treatment effectively reduced early postoperative pain and improved recovery after hepatectomy.

RESUMO

INTRODUCTION: Percutaneous nephrolithotomy is a procedure used for management of refractory renal calculi. Oral and parenteral opioids, along with local anesthetic infiltration, neuraxial anesthesia, and paravertebral blocks are the most common methods of managing intra-operative and post-operative pain for these patients. The erector spinae plane block with catheter (ESPC) is a newer interfascial regional anesthetic technique that can be used to manage peri-operative pain in these patients. CLINICAL FINDINGS: Three patients complained of significant flank pain were scheduled for percutaneous nephrolithotomy under general anesthesia in the prone position. DIAGNOSES: Patients were diagnosed with large renal calculi. THERAPEUTIC INTERVENTIONS: Patients received ESPC in the pre-operative holding area at the level of the T7 transverse process. The ESPCS were bolused with a solution of 30 mL 0.25% bupivacaine with 4 mg dexamethasone prior to surgery. Patients also received oral tramadol 50 mg and acetaminophen 1 g as part of the multimodal pain protocol prior to surgery. After the procedure, the patients were bolused with 0.25% bupivacaine or started on an infusion of 0.25% bupivacaine to manage their pain. OUTCOMES: No opioid or other pain medications, other than the local anesthetic solution given in the ESPCs, were used during the intra-operative or post-operative period for management of pain in these patients. Visual analogue scale (VAS) scores were below 4 for all patients in the post-operative period, and patients did not report any issues with post-operative nausea or vomiting. CONCLUSION: These patients were compared to 3 prior patients who had undergone percutaneous nephrolithotomy without ESPC. The 3 patients without ESPC placement reported increased VAS scores, had increased opioid/pain medication consumption intraoperatively and postoperatively, and had increased incidence of perioperative nausea when compared to our ESPC patients. Our report shows that ESPC, in combination with a multimodal pain protocol, can be a good option for management of patients undergoing percutaneous nephrolithotomy.

RESUMO

Different neural signal blocking technologies provide potential therapy for various diseases caused by pathological or involuntary neural activities. In this paper, a novel neural signal blocking concept based on spike-trapping principle is introduced. The blocking system was designed and implemented. In the system, a compound action potential was induced by a proximal stimulus, and a blocking signal was generated after a neural signal was detected, which was applied to the distal end of the nerve to block the nerve conduction. The reliability of the system was verified on bullfrog sciatic nerve gastrocnemius muscle specimens. The optimal blocking signal parameters, the relationship between nerve diameter and blocking threshold voltage, and the nerve safety of blocking signals were explored. The experimental results show that the system is possible to block a pathological or involuntary neural signal automatically. The average voltage of block threshold and the minimum pulse width are -1.66 V and 120 ms, respectively. The blocking threshold decreases as the diameter of the nerve increases. The blocking signals at the threshold level are safe for the stimulated nerve.

RESUMO

BACKGROUND: Total knee arthroplasty (TKA) is an established and successful surgical procedure which is the major treatment for degenerative knee joint diseases. A novel technique to address posterior knee joint pain is the infiltration of local anesthetic between the interspace between the popliteal artery and capsule of the knee (IPACK). The goal of this randomized clinical trial was to assess the efficacy and safety of adding IPACK to adductor canal block (ACB) after TKA. METHODS: This was a prospectively randomized trial that investigated the effectiveness and safety of the IPACK after TKA. Approval from Clinical Studies Ethical Committee in Qilu Hospital of Shandong University was obtained. The inclusion criteria were adult patients undergoing primary unilateral TKA and American Society of Anesthesiologists grade 1 or 2 with normal cognitive function. The patients were randomized to 1 of 2 treatment options: ACB-alone group and ACB + IPACK group. The primary outcome was the total morphine consumption during postoperative 24 hours. Secondary outcomes included postoperative pain score, time to first and total dosage of rescue morphine in postoperative 48 hours, early and late postoperative period (from postoperative day 0-3 months follow-up) performance-based test (Timed-Up and Go test, and quadriceps strength). Postoperative nausea and vomiting, length of hospital stay, patient satisfaction, and other adverse events were also evaluated. RESULTS: It was hypothesized that when combined with a control group, the IPACK block would result in a lower morphine consumption and pain score after TKA. TRIAL REGISTRATION: This study protocol was registered in Research Registry (researchregistry5765).

RESUMO

Objective: To investigate the effects of thoracoscopy-guided thoracic paravertebral block for analgesia after single-port video-assisted pulmonary lobectomy. Methods: From December 2019 to April 2020, 60 patients receiving single-port video-assisted pulmonary lobectomy at Ningbo Medical Center Lihuili Hospital were selected. The patients were randomly and equally divided into control group and paravertebral block group using a random number table. Patients of paravertebral block group were injected into the thoracic 4-5 intercostal, paravertebral 1 cm using 0.375% ropivacaine (20 ml) with thoracoscopy-guided at the end of surgery, while patients of control group were given patient controlled intravenous analgesia (PCIA). Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of postoperative adverse reactions, additional dose and times of pethidine, the time to resume eating, the rate of postoperative active cough, the first time to get out of bed after surgery and postoperative hospital stay of two groups' patients were recorded. t test and chisquare test were used for statistical analysis. Results: The VAS score of paravertebral block group were lower than those of control group at all time points (all P<0.05). The Ramsay sedation scale of paravertebral block group were higher than those of control group at all time points (all P<0.05). The additional dose and times of pethidine of paravertebral block group were (8.2±2.3) mg and (0.2±0.1) time, which were lower than (87.8±15.3) mg and (1.8±0.3) time of control group, the differences were statistically significant (t=28.91, 34.37, all P<0.05). Incidence of nausea, vomiting and pruritus of paravertebral block group were 10.0%, 6.7% and 0, which were lower than 40.0%, 30.0% and 13.3% of control group, the differences were statistically significant (χ(2)=7.20, 5.45, 4.29, all P<0.05). The rate of postoperative active cough of paravertebral block group was 33.3%, which was higher than 10.0% of control group, the difference was statistically significant (χ(2)=4.81, P<0.05). The time to resume eating, the first time to get out of bed after surgery and postoperative hospital stay were (6.5±0.4) h, (20.9±3.1) h and (4.6±1.0) d, which were lower than (8.5±0.7) h, (28.6±4.8) h and (6.1±1.3) d of control group, the differences were statistically significant (t=13.47, 7.39, 4.19, all P<0.05). Conclusion: Thoracic paravertebral block under thoracoscopy-guided can effectively reduce the postoperative pain of single-port thoracoscopic lobectomy, with fewer adverse reactions, and is beneficial to postoperative recovery.

RESUMO

RATIONALE: The anesthetic management of patients with severe pulmonary hypertension is different from that of normal, healthy patients, and regional nerve blocks are commonly used for them. Due to the individual variability of the course, distribution, and branching of the nerves below the inguinal ligament, the supra-inguinal fascia iliaca (SIFI) block has a wider and more stable blocking area. In combination with the sacral plexus block, they can satisfy the needs of surgical anesthesia below the hip. PATIENT CONCERNS: A 46-year-old man with tuberculosis, chronic obstructive pulmonary disease, pulmonary heart disease, World Health Organization (WHO) class III pulmonary hypertension and right heart dysfunction, and American Society of Anesthesiologists physical status class III needed fixation of an intramedullary nail in the left lower extremity. Additionally, he had broken his left lower limb after a recent fall. Both general anesthesia and epidural anesthesia were not appropriate. DIAGNOSES: The patient had a clear history of tuberculosis, computerized tomography scan displayed destructive pneumonophthisis. Furthermore, he had chronic obstructive pulmonary disease and pulmonary heart disease. INTERVENTIONS: An ultrasound-guided SIFI combined with a sacral plexus block was successfully performed for surgical anesthesia and avoided all hemodynamic fluctuations. OUTCOMES: We successfully performed an ultrasound-guided SIFI combined with a sacral plexus block for surgical anesthesia and avoided all hemodynamic fluctuations. LESSONS: Ultrasound-guided suprainguinal fascia iliaca block combined with a sacral plexus block can be suitable for anesthesia for patients with severe circulatory compromise.

RESUMO

BACKGROUND: Total knee arthroplasty (TKA) is known to be a painful orthopedic procedure and moderate to severe pain is common, especially immediately postoperatively and during active motion. The aim of the present study was to compare epidural analgesia (EA) and adductor canal block (ACB) techniques with regard to early period pain levels, need for additional opioids, and ambulation and functional scores in patients who had undergone primary TKA. METHODS: Approval for the study was granted by the Changji Branch of the First Affiliated Hospital of Xinjiang Medical University. Written informed consent will be obtained from all of the participants. Inclusion criteria included the following: planned unilateral TKA; spinal anesthesia; American Society of Anesthesiologists physical status classification score of I to III. Prospective assessment will be done for 100 patients who are scheduled for unilateral primary TKA surgery in our academic hospital by a single senior surgeon between August 2020 and December 2021. Patients were randomized to ACB treatment or EA treatment by a computer random number generator. The primary outcome was visual analog scale pain scores in the immediate postoperative period. Secondary outcomes included postoperative opioid use, length of hospital stay, activity level during physical therapy, and knee range of motion. Results were evaluated in a confidence interval of 95% and at a significance level of P < .05. CONCLUSIONS: We hypothesized that standard ACB would be as effective as EA for postoperative pain management following TKA. TRIAL REGISTRATION: This study protocol was registered in Research Registry (researchregistry5775).

RESUMO

Ultrasound-guided interscalene block (US-ISB) and nerve stimulator-guided interscalene block (NS-ISB) have both been commonly used for anesthesia in shoulder arthroscopic surgery.This study aims to compare which method provides surgical block as a sole anesthesia. In this retrospective study, 1158 patients who underwent shoulder arthroscopic rotator cuff tear repair surgery under ISB between October 2002 and March 2018 were classified into either the US-ISB or NS-ISB anesthesia groups. Demographic and anesthetic characteristics and intraoperative medications were analyzed after propensity score matching and compared between the 2 groups.There was a 0.5% rate of conversion to general anesthesia in the US-ISB group and a 6.7% rate in the NS-ISB group (P < .001). The volume of local anesthetics used for ISB was 29.7 ±â€Š8.9 mL in the US-ISB group versus 38.1 ±â€Š4.8 mL in the NS-ISB group (P < .001). The intraoperative use of analgesics and sedatives such as fentanyl, midazolam and propofol in combination was significantly lowered in the US-ISB group (P < .001).US-ISB is a more effective and safer approach for providing intense block to NS-ISB because it can decrease the incidence of conversion to general anesthesia and reduce the use of analgesics and sedatives during arthroscopic shoulder surgery.

RESUMO

BACKGROUND: Pain control after total knee arthroplasty has shown many advances; however, the optimal method remains controversial. The purpose of this present study is to assess the efficacy and safety of the addition of local infiltration analgesia to adductor canal block for pain control after primary total knee arthroplasty. METHODS: This prospective randomized controlled research was conducted from January 2018 to June 2019. All the patients and their family members signed the informed consent forms, and this work was authorized via the ethics committee of Jinxiang Hospital Affiliated to Jining Medical College (JXHP0024578). Inclusion criteria were 55 years old or older, who possess the physical status I-III of American Society of Anesthesiologists, and the body mass index in the range of 18 to 30 kg/m. Exclusion criteria were regional and/or neuroaxial anesthesia contraindications, the history of drug allergy involved in the research, neuropathic pain, as well as the chronic pain requiring opioid therapy. Seventy-two patients were divided into 2 groups randomly. Study group (n = 36) received both adductor canal block and local infiltration analgesia. Control group (n = 36) received adductor canal block alone. Primary outcome included postoperative pain score (visual analog scale 0 to 10 cm, in which 0 represents no pain and 10 represents the most severe imaginable pain). The measures of secondary outcome included the knee range of motion, opioid consumption, the hospital stay length as well as the postoperative complications (for instance, pulmonary embolism, deep vein thrombosis, and the wound infection). All the analyses were conducted through utilizing the SPSS for Windows Version 20.0. RESULTS: The results will be shown in .(Table is included in full-text article.) CONCLUSION:: The study will provide more evidence on the combination use of adductor canal block and local infiltration analgesia in the treatment of pain after the total knee arthroplasty.

RESUMO

To evaluate the effectiveness and safety of performing nerve blocks on the articular branches of the suprascapular and subscapular nerves for the treatment of shoulder pain caused by various pathologies.Fifty-two patients with shoulder pain were included in this study. Suprascapular and subscapular nerve blocks were performed with 2.5 mL anesthetic solution (2 mL of 0.5% bupivacaine and 0.5 mL of 2 mg/mL dexamethasone). The subjects were evaluated before the procedure and 1, 3, and 6 months afterward by means of the numeric rating scale and the shoulder pain and disability index. A post-injection pain reduction of >50% and <50% was considered a positive and negative response to the blocks, respectively.After nerve blocks, the mean numeric rating scale and shoulder pain and disability index scores were significantly reduced from pre-injection values, and this effect persisted for 6 months after injection. The positive and negative response groups consisted of 31 (60%) and 21 (40%) patients, respectively. The positive response group showed significantly better outcomes on the numeric rating scale and shoulder pain and disability index compared with the negative response group. No patients reported adverse effects either during or after the procedure.Performing nerve blocks on the articular branches of the suprascapular and subscapular nerves resulted in positive outcomes for shoulder pain patients. Regardless of shoulder pathology, this new injection method can be safely used in shoulder pain patients.

RESUMO

BACKGROUND: Several studies reported short-term analgesic efficacy of obturator nerve block (ONB), as in comparison with the femoral nerve block (FNB) in the treatment of postoperative pain after the total knee replacement (TKR). The optimal method remains under debate. The purpose of our current work is to compare the safety and efficacy of FNB and ONB for postoperative analgesia after TKR. METHODS: This prospective, randomized, and controlled study was performed from January 2018 to December 2019. It was authorized via the Institutional Review Committee in NO.971 Hospital of the People's Liberation Army Navy (2019-PLAN-132).Two hundred patients were divided randomly into 2 groups, the control group (n = 100) and study group (n = 100). The experimental group received FNB and control groups received ONB. Primary outcome included pain at different time point (Visual Analogue Scale score of anterior knee pain at rest and in motion). The Visual Analogue Scale scores were marked by patients themselves on a paper with a graduated line starting at 0 (no pain) and ending at 10 (the most painful). Opioid consumption was converted to equivalents of oral morphine uniformly for statistical analysis. Secondary outcomes included the knee range of motion, the hospital stay length as well as the postoperative complications such as pulmonary embolism and deep vein thrombosis. RESULTS: Table 1 will show the clinical outcomes between the 2 groups. CONCLUSION: This trial would provide an evidence for the use of different types of peripheral nerve blocks in TKR.

RESUMO

BACKGROUND: Pain management after the total joint arthroplasty is still challenging, but worthy of attention, because good pain management can improve the outcomes of patient. It is still controversial whether fascia iliaca compartment block (FICB) can effectively decrease the opioid consumption and pain after total hip replacement (THR) owing to the number of published investigations is small. The purpose of this present study is to assess the efficacy and safety of FICB for postoperative analgesia after THR. METHODS: This is a single center, placebo-controlled randomized trial which is performed in accordance with the SPIRIT Checklist for randomized studies. It was authorized via the Chifeng Municipal Hospital institutional review committee (H2020-19-8). 100 patients undergoing THR will be included in this study. Patients are randomly divided into 2 groups: FICB group or Non-FICB group, FICB with 5mgmL of epinephrine and 40 mL of ropivacaine 0.2%. Primary outcomes are pain score at different time point. Visual analog scale is used to assess the pain (10: the maximum possible pain and 0: absent pain). The secondary outcomes are the postoperative complications, length of hospital stay and total consumption of opioid. All the needed analyses are implemented through utilizing SPSS for Windows Version 15.0. RESULTS: Figure 1 will show the primary and secondary outcomes. CONCLUSION: This trial can provide an evidence for the use of FICB for analgesia after THR.
