Ultrasound-guided continuous femoral nerve block vs continuous fascia iliaca compartment block for hip replacement in the elderly: A randomized controlled clinical trial (CONSORT)

Implementation of a Fascia Iliaca Compartment Block Program in Geriatric Hip Fractures: The Experience at a Level I Academic Trauma Center

OBJECTIVES

Determine adherence to a newly implemented protocol of fascia iliaca compartment block (FICB) in geriatric hip fractures.

METHODS

DESIGN

Retrospective review.

SETTING

Level I trauma center.

PATIENT SELECTION CRITERIA

Patients with a hip fracture treated with cephalomedullary nailing or hemiarthroplasty (CPT codes 27245 or 27236).

OUTCOME MEASURES AND COMPARISONS

Adherence to a protocol for FICB, time intervals between emergency department arrival, FICB, and surgery stratified by time of admission.

RESULTS

Three hundred eighty patients were studied (average age 78 years, 70% female). Approximately 53.2% of patients received an FICB, which was less than a predefined acceptable adherence rate of 75% ( P < 0.001). Approximately 5.0% received an FICB within 4 hours and 17.3% within 6 hours from admission. Admission during daylight hours (7 am -7p m ) when compared with evening hours (7 pm -7 am ) was associated with improved timeliness ([8.3% vs. 0% within 4 hours, P < 0.001] [27.5% vs. 2.4% within 6 hours, P < 0.001]). Improved adherence to the protocol was observed over time (odds ratio: 1.0013, 95% confidence interval, 1.0001-1.0025, P = 0.0388).

CONCLUSIONS

FICB implementation was poor but gradually improved over time. Few patients received an FICB promptly, especially during night hours. Overall, this study demonstrates that implementation of an FICB program at a Level I academic trauma center can be difficult; however, many hurdles can be overcome with institutional support and dedication of resources such as staff, space, and additional training.

Nerve block reduces the incidence of 3-year postoperative mortality: a retrospective cohort study

Purpose

A retrospective cohort study was performed to determine the effect of nerve block on the incidence of postoperative mortality in patients with hip replacement.

Methods

According to the inclusion and exclusion criteria, patients who were undergoing hip replacement for the first time under general or intraspinal anesthesia, classified as ASA class I-IV, and aged ≥65 years were selected. We collected the general data, past medical history, preoperative laboratory test results, perioperative fluid intake and outflow data, perioperative anesthesia and related drug data, postoperative laboratory results, and correlation time index. Patients with preoperative combined nerve block were included in the N group, and those without combined nerve block were included in the NN group. The patients were followed up via telephone call to assess survival outcomes at 3 years after surgery. Propensity score matching and uni- and multivariate analyses were performed to determine the influence of nerve block and other related factors on postoperative mortality.

Results

A total of 743 patients were included in this study, including 262 in the N group and 481 in the NN group. Two hundred five patients in both groups remained after propensity score matching. Main result: Preoperative nerve block was associated with reduced mortality three years after surgery.

Conclusion

Nerve block reduces the incidence of 3-year postoperative mortality, and composite nerve block with general anesthesia and neuraxial anesthesia is worthy of promotion.

Ultrasound-guided femoral nerve block versus fascia iliaca compartment block for femoral fractures in emergency department: A randomized controlled trial

Aim

Femoral fractures are one of the most debilitating injuries presenting to the emergency departments (EDs). The pain caused by these fractures is typically managed with opioids and adjunctive regional analgesia. These approaches are often associated with adverse side effects. Thus, appropriate alternative methods should be thoroughly investigated. To evaluate ultrasound-guided femoral nerve block (FNB) with ultrasound-guided fascia iliaca compartment block (FICB) in femoral fractures, to determine which provides better analgesia and less opioid requirement.

Methods

This study was a randomized clinical trial performed on adult patients presenting to the ED within 3 h of isolated femoral fracture with initial numerical pain rating scale (NRS-0) score of more than 5. The patients were randomized to receive FNB or FICB. The outcomes were block success rates, pain at 20 (NRS-20) and 60 (NRS-60) min after the end of the procedures, as well as the number and total dose of fentanyl administration during ED stay.

Results

Eighty-seven patients were recruited (40 FNB and 47 FICB). Success rates were 82.5% in FNB and 83.0% in FICB group, with no significant difference between the groups. NRS-20, NRS-60, the number of patients who received supplemental fentanyl, and the total dose of administered fentanyl were significantly lower following FNB. However, the length of the procedure was significantly lower in the FICB group.

Conclusion

Both FNB and FICB are effective in pain reduction for fractures of femur, but FNB provides more pain relief and less need for supplemental fentanyl.

Ultrasound-Guided Peripheral Nerve Blocks for Hip Surgery: A Concise Perspective

Ultrasound implementation for the facilitation of peripheral nerve blocks is well established. Ultrasound-guided lumbar plexus, femoral, fascia iliaca and supra-inguinal fascia iliaca compartment, pericapsular nerve group and quadratus lumborum nerve blocks have been employed for analgesia purposes in hip surgery. The combination of motor-sparing regional anesthesia strategies for optimal postoperative pain control with recovery protocols targeting to early and safe patients' mobilization constitute the current dogma of orthopedic surgery. Therefore, this editorial sets out to revisit the role of peripheral nerve blocks in postoperative pain management of hip surgery patients, under the prism of current orthopedic practice.

Comparison of Femoral Nerve Block and Fascia Iliaca Block for Proximal Femoral Fracture in the Elderly Patient: A Meta-analysis

Introduction

Pain management modalities after proximal femoral fracture are variable and have been studied extensively. Regional anesthesia, specifically femoral nerve (FNB) and fascia iliaca compartment blocks (FICB), can be used to provide analgesia preoperatively.

Methods

Systematic searches of all related literature were conducted in the Medline, Embase, and Cochrane Central Register of Controlled Trials databases. Randomized controlled trials (RCTs) of proximal femoral fractures were included. The pain scores at different time points, opioid requirement in 24 h, mean arterial pressure, time for spinal anesthesia, patient satisfaction, and incidence of side effects between the 2 groups were extracted throughout the study.

Results

Fifteen RCTs including 1240 patients met the inclusion criteria. The present meta-analysis indicated that compared with FNB, FICB could decrease the visual analog scale (VAS) scores at 4 h after surgery (P < .05). The incidence of side effects (nausea, vomiting, and sedation) was lower in the FNB group (P < .05). Compared to the FICB, no significant difference was found at any other observed time point. Additionally, no difference was found in opioid requirement at 24 h, mean arterial pressure, time for spinal anesthesia, or patient satisfaction (P > .05).

Conclusions

FICB demonstrates a reduction in VAS score at 4 while FNB decreases the risk of several adverse events. More high-quality RCTs are necessary for proper comparison of the efficacy and safety of FNB and FICB.

Is Femoral Nerve Block Superior to Fascia Iliac Block in Hip Surgery? Meta-Analysis of Randomized Controlled Trials

Background. Femoral nerve block (FNB) and fascia iliac compartment block (FICB) are alternative methods of pain relief during hip surgery. Nevertheless, the effectiveness and safety of FNB compared with FICB are yet to be fully determined. Methods. Electronic databases were systematically searched. Only randomized controlled trials (RCTs) on hip surgery were included. Postoperatively, the pain scores at different time points, narcotic requirements in 24 h, mean arterial pressure, spinal anesthesia (SA) time, patient satisfaction, and adverse effect rates between the two groups were extracted throughout the study. Results. Fourteen RCTs including 1179 patients were included. Compared to the FICB, FNB decreased the VAS scores postoperatively at 24 h at rest ( $P<0.05$ ) and the incidence rate of some side effects (nausea, vomiting, and sedation) ( $P<0.05$ ). However, compared to the FICB, no significant difference was found in the FNB regarding the VAS scores postoperatively at any of the other time points (2 min, 20 min, 2 h, 24 h at movement, 48 h at rest, and 48 h at movement). Patients in both groups had similar narcotic needs after 24 h, mean arterial pressure, SA time, and patient satisfaction ( $P>0.05$ ). Conclusions. FNB has more advantages in reducing VAS scores postoperatively at 24 h at rest and the odds of some adverse effects. A better quality RCT is needed to properly compare FNB with FICB.

The Effect of Fascia Iliaca Compartment Blockade on Mortality in Patients With Hip Fractures: Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVE

The purpose of this meta-analysis was to determine whether perioperative fascia iliaca compartment blockade (FICB) decreases mortality in patients with hip fracture.

METHODS

MEDLINE (PubMed and Ovid platforms), Web of Science, EMBASE, and Cochrane Database of Systemic Reviews were screened for "fascia iliaca compartment block, hip fracture" articles in English, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, from January 1, 2005, to March 1, 2020. All relevant randomized controlled trials and cohort and case-control studies were included for analysis. Relevant article titles were identified, and their corresponding abstracts were independently reviewed by two authors for inclusion. The full-text articles were then obtained for all relevant identified abstracts and assessed for inclusion in the meta-analysis. Conflicts in quality assessment between the two independent reviewers were resolved by a consensus vote of all authors.

RESULTS

Study quality was assessed objectively using the Jadad and Newcastle-Ottawa Scale. This meta-analysis was done in accordance with the PRISMA (http://links.lww.com/JAAOS/A731) and QUORUM guidelines. Quantitative synthesis analysis was done using Cochrane Reviews Review Manager (version 5.3). All analyses were completed using random-effects models and comparing the individual effect sizes within each study.

DISCUSSION

Management of hip fracture pain with FICB does not markedly decrease short-term mortality. Our findings support the continued use of FICB for the management of hip fractures in geriatric patients and suggest the need for future prospective randomized controlled trials to further determine FICB's effect on short-term and long-term mortality and functional status.

LEVEL OF EVIDENCE

Efficacy of dexmedetomidine as an adjuvant in femoral nerve block for post-op pain relief in hip surgery: A prospective randomized double-blind controlled study

Background and Aims:

To determine whether the addition of dexmedetomidine either in peripheral block or via systemic route leads to prolongation of the duration of analgesia is inconclusive. The present study aimed to assess the duration of postoperative analgesia with dexmedetomidine used as an additive with bupivacaine for ultrasound-guided femoral nerve block (FNB) and to compare it with intramuscular dexmedetomidine along with FNB.

Material and Methods:

A prospective, double-blind randomized clinical trial involving adult patients undergoing elective hip surgery, performed under subarachnoid block. When sensory block receded to T12 after the surgery, FNB was given for postoperative analgesia. Patients were randomized into three groups; Group A received FNB with 40 mL 0.25% bupivacaine and 0.5 mL saline as IM injection, Group B received FNB with 39.5 mL of 0.25% bupivacaine + 0.5 mL (50 mcg) of dexmedetomidine in the affected limb and 0.5 mL saline IM injection, and Group C received FNB with 40 mL of 0.25% bupivacaine and 0.5 mL (50 mcg) of dexmedetomidine as IM injection. Postoperative pain was assessed and for pain with VAS score >3, intravenous tramadol was given as rescue analgesia. Chi-square test for categorical variables and one-way ANOVA for continuous variables.

Results:

The mean duration of analgesia in groups A, B, and C was 671, 676, and 490 min, respectively which was not significant. A 24 h analgesic requirement was also not different between the groups.

Conclusion:

The use of dexmedetomidine perineurally or systemically did not prolong the duration of analgesia as compared to bupivacaine alone for femoral nerve block.

Combined fascia iliaca compartment block and monitored anesthesia care for geriatric patients with hip fracture: Two case reports

BACKGROUND

Major hip surgery usually requires neuraxial or general anesthesia with tracheal intubation and may be supplemented with a nerve block to provide intraoperative and postoperative pain relief.

CASE SUMMARY

This report established that hip surgical procedures can be performed with a fascia iliaca compartment block (FICB) and monitored anesthesia care (MAC) while avoiding neuraxial or general anesthesia. This was a preliminary experience with two geriatric patients with hip fracture, American Society of Anesthesiologists status III, and with many comorbidities. Neither patient could be operated on within 48 h after admission. Both general anesthesia and neuraxial anesthesia were high-risk procedures and had contraindications. Hence, we chose nerve block combined with a small amount of sedation. Intraoperative analgesia was provided by single-injection ultrasound-guided FICB. Light intravenous sedation was added. Surgical exposure was satisfactory, and neither patient complained of any symptoms during the procedure.

CONCLUSION

This report showed that hip surgery for geriatric patients can be performed with FICB and MAC, although complications and contraindications are common. The anesthetic program was accompanied by stable respiratory and circulatory system responses and satisfactory analgesia while avoiding the adverse effects and problems associated with either neuraxial or general anesthesia.

PROSPECT guideline for total hip arthroplasty: a systematic review and procedure-specific postoperative pain management recommendations

The aim of this systematic review was to develop recommendations for the management of postoperative pain after primary elective total hip arthroplasty, updating the previous procedure-specific postoperative pain management (PROSPECT) guidelines published in 2005 and updated in July 2010. Randomised controlled trials and meta-analyses published between July 2010 and December 2019 assessing postoperative pain using analgesic, anaesthetic, surgical or other interventions were identified from MEDLINE, Embase and Cochrane databases. Five hundred and twenty studies were initially identified, of which 108 randomised trials and 21 meta-analyses met the inclusion criteria. Peri-operative interventions that improved postoperative pain include: paracetamol; cyclo-oxygenase-2-selective inhibitors; non-steroidal anti-inflammatory drugs; and intravenous dexamethasone. In addition, peripheral nerve blocks (femoral nerve block; lumbar plexus block; fascia iliaca block), single-shot local infiltration analgesia, intrathecal morphine and epidural analgesia also improved pain. Limited or inconsistent evidence was found for all other approaches evaluated. Surgical and anaesthetic techniques appear to have a minor impact on postoperative pain, and thus their choice should be based on criteria other than pain. In summary, the analgesic regimen for total hip arthroplasty should include pre-operative or intra-operative paracetamol and cyclo-oxygenase-2-selective inhibitors or non-steroidal anti-inflammatory drugs, continued postoperatively with opioids used as rescue analgesics. In addition, intra-operative intravenous dexamethasone 8-10 mg is recommended. Regional analgesic techniques such as fascia iliaca block or local infiltration analgesia are recommended, especially if there are contra-indications to basic analgesics and/or in patients with high expected postoperative pain. Epidural analgesia, femoral nerve block, lumbar plexus block and gabapentinoid administration are not recommended as the adverse effects outweigh the benefits. Although intrathecal morphine 0.1 mg can be used, the PROSPECT group emphasises the risks and side-effects associated with its use and provides evidence that adequate analgesia may be achieved with basic analgesics and regional techniques without intrathecal morphine.

Femoral nerve block versus fascia iliaca block for pain control in knee and hip arthroplasties: A meta-analysis

BACKGROUND

This meta-analysis aimed to compare the efficiency of fascia iliaca compartment block (FICB) and femoral nerve block (FNB) for pain management in knee and hip surgeries.

METHODS

We searched four electronic databases (Pubmed, Embase, Cochrane library database, Web of Science) from inception to January 2019. Only randomized controlled trials (RCTs) were included. Two review authors independently extracted data for each included study. Primary outcomes were visual analogue scale at 12 hours, 24 hours, 48 hours, total morphine consumption, the length of hospital stay and the occurrence of nausea and vomiting. Standardized mean difference (SMD) or risk ratio (RR) and 95% confidence intervals (CIs) were calculated for continuous outcomes and discontinuous outcomes respectively. We used the Cochrane Risk of Bias tool to assess risk of bias. Stata 12.0 was used for meta-analysis.

RESULTS

Finally, 7 RCTs involving 508 patients (FICB = 254, FNB = 254) were included in this meta-analysis. Compared with FNB group, FICB has no benefit for visual analogue scale at 12 hours (SMD = 0.02, 95% CI, -0.15 to 0.19; P = .820), 24 hours (SMD = -0.02, 95% CI, -0.22 to 0.18; P = .806), and 48 hours (SMD = -0.02, 95% CI, -0.22 to 0.19; P = .872). No significant differences were found regarding total morphine consumption (SMD = -0.07, 95% CI, -0.29 to 0.15; P = .533). What's more, there was no significant difference between the length of hospital stay and the occurrence of nausea and vomiting (P > .05).

CONCLUSION

FICB has equivalent pain control and morphine-sparing efficacy when compared with FNB. More high-quality RCTs are needed to identify the optimal drugs and volume of local infiltration protocols.

Improvement of analgesic efficacy for total hip arthroplasty by a modified ultrasound-guided supra-inguinal fascia iliaca compartment block

Background

Fascia iliaca compartment block (FICB) is an anterior approach to the lumbar plexus block and provides the effective adjunctive analgesia for total hip arthroplasty (THA).

Methods

As a case series study, 28 patients (≥ 65 years old) with THA were received a modified in-plane ultrasound-guided supra-inguinal (S-FICB) as an analgesic adjunct to evaluate the analgesic effectiveness and the local anesthetic diffusion with magnetic resonance imaging (MRI). A combination of propofol and sufentanil was administered to conduct target-controlled infusion.

Results

The pain scores were 1 (0–4), 2 (1–5), 3 (1–6) and 3 (1–6) at 4, 8, 12, and 24 h. The cumulative opioids were 8 (8–12), 18 (16–32), 28 (24–54) and 66 (48–104) mg of i.v. morphine equivalents at 4, 8, 12, and 24 h. The patient-controlled analgesia (PCA) times were 0 (0–1), 1 (0–2), 2 (0–5) and 5 (3–8) at 4, 8, 12, and 24 h. In lateral, anterior and medial part of thigh, the sensory blockade in 28 patients was 23 (82 %), 21 (75 %) and 19 (68 %) at 5 min; 28 (100 %) at 10 and 20 min. Motor blockade of femoral nerve (FN) and obturator nerve (ON) was present in 13 (46 %) and 3 (11 %) patients at 5 min, 24 (86 %) and 9 (32 %) at 10 min, 26 (93 %) and 11 (39 %) at 20 min. Injectate permeated to the FN and extended superiorly over the surface of iliac muscle (IM) and pectineus muscle (PM) in all patients.

Conclusions

The modified S-FICB has provided an effective postoperative analgesic adjunct after THA with the satisfactory blockade of femoral (FN), obturator (ON) and sciatic (SN) nerves, especially for ON, when compared with the existing techniques.

Comparative study to evaluate the effect of ultrasound-guided pericapsular nerve group block versus fascia iliaca compartment block on the postoperative analgesic effect in patients undergoing surgeries for hip fracture under spinal anesthesia

Background:

Fractures in and around the hip are a major concern in young as well as the elderly. Ultrasound-guided (USG) peripheral nerve blocks help in early surgical fixation of these fractures by providing perioperative pain relief as well as early mobilization resulting in reduced morbidity and mortality.

Aims:

This study aims to compare the efficacy of USG pericapsular nerve group (PENG) block versus fascia iliaca compartment (FIC) block.

Setting and Design:

Prospective, randomized, double-blind, controlled study.

Materials and Methods:

Twenty-four patients above 18 years of age with hip fracture belonging to the American Society of Anaesthesiologists physical status Classes I and II scheduled for hip surgery were randomly allocated into two groups. Group 1(PENG block) received USG-guided PENG block and Group 2 (FIC block) received USG guided FIC block for postoperative pain relief. Postoperative pain relief (at rest) was evaluated by Numeric Rating Scale score from 20^th min and at regular interval for 24 h. The total analgesic consumption in the first 24 h was also noted.

Statistical Analysis Used:

Data were analyzed by using nonparametric test and Chi-square test. Hemodynamic variables and pain scores were analyzed using analysis of variance for two groups and independent t-test was used for comparison between two groups.

Results:

Postoperative NRS score was higher in FIC block than PENG block which was statistically significant at 1 h (P = 0.035) and at 4 h (P = 0.001). The first requirement of analgesic was significantly late in PENG block group (8.17 ± 3.129) as compared to FIC block group (4.00 ± 1.477).

Conclusions:

PENG block provides better postoperative analgesia, with reduced requirement of rescue analgesics in 24 h as compared to FIC block in patients undergoing surgeries for hip fracture under spinal anesthesia.

Ultrasound-guided suprainguinal fascia iliaca block combined with a sacral plexus block for lower extremity surgery: A case report

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.

A Randomized Controlled Trial of FNB versus FICB for Patients with Femoral Neck Fractures Before Spinal Anesthesia

Background and Objectives

Patients with femoral neck fractures often suffer severe pain. This randomized controlled clinical study compared the effect of femoral nerve block (FNB) and fascia iliaca compartment block (FICB) in this population.

Patients and Methods

Forty-six patients were randomly assigned to one of the two groups: FNB group (femoral nerve block, n=23) or FICB group (fascia iliaca compartment block, n=23). Before positioning for spinal anesthesia, patients received FNB with 15 mL of 0.5% ropivacaine or FICB with 40 mL of 0.5% ropivacaine. Pain was evaluated using a visual analogue scale (VAS) at rest and during hip flexion after admission to the operation room; at 3, 5, 8, and 10 min after analgesia intervention; and during positioning for spinal anesthesia. Positioning was attempted after 10 min of analgesia intervention in each group. Time required to perform spinal anesthesia, quality of positioning, and patient satisfaction were documented.

Results

The VAS scores in the FNB group were significantly lower than those in FICB group at 3 and 5 min after analgesia intervention (P=0.000). However, there were no significant differences in VAS between groups at 8 or 10 min or during positioning.

Conclusion

FNB and FICB produce similar analgesic effects in patients with femoral neck fractures, but FNB has a more rapid onset of pain relief.

Combination of post-fascia iliaca compartment block and dexmedetomidine in pain and inflammation control after total hip arthroplasty for elder patients: a randomized control study

Objective

This study aims to investigate the efficiency of fascia iliaca compartment block (FICB) combined with dexmedetomidine (DEX) in postoperative and inflammation management for elder patients after total hip arthroplasty.

Methods

The present randomized controlled study included a total of 119 elder patients who received total hip arthroplasty in our hospital from March 2016 to December 2018. These patients were divided into three groups: control group, patients received routine general anesthesia; FICB group, patients received additional FICB after surgery; and combined group, patients received both pre-treatment of DEX and post-treatment of fascia iliaca compartment block. The serum levels of interleukin (IL)-1β, IL-6, and C-reactive protein (CRP) were measured by ELISA. The visual analog scale (VAS) score was measured at 12, 24, 48, and 72 h after surgery, and the patient-controlled intravenous analgesia (PCIA) pressing time within 48 h after surgery was also recorded. The Pittsburgh sleep quality index (PSQI) was used to measure the sleep quality before and at 1 month after surgery.

Results

The VAS scores were significantly lower in patients in the combined group, when compared with the other two groups, at 12, 24, 48, and 72 h after surgery. In addition, the VAS scores at all time points were significantly lower in the FICB group than the control group. The PCIA pressing times were also remarkably lower in the combined group. At 4, 24, 48, and 72 h after surgery, the serum levels of these inflammatory factors were the lowest in the combined group, and the PSQI scores were significantly lower in the combined group, when compared with the other two groups, while the control group had the highest PSQI scores among the three groups. There was no severe side effects and significant difference observed.

Conclusion

FICB combined with DEX reduced the postoperative pain, improved the sleep condition, and decreased the serum levels of inflammatory factors after total hip arthroplasty.

Perioperative multidisciplinary implementation enhancing recovery after hip arthroplasty in geriatrics with preoperative chronic hypoxaemia

We investigated risk factors for postoperative serious adverse events (SAEs) in elderly patients with preoperative chronic hypoxaemia undergone total hip arthroplasty (THA) or hemiarthroplasty and performed an implementation to modify and improve clinical outcome. A retrospective medical record review was performed to identify geriatric patients who receiving THA or hemiarthroplasty at a single university teaching hospital, Kunming, Yunnan, China between January 2009 and August 2017. Total of 450 elderly patients were included in the study. Data were collected on baseline characteristics, detailed treatments, and adverse events. Univariate and multivariate logistic regression analysis were used to identify risk factors for SAEs. In multivariate regression analysis, a higher occurrence of general anaesthesia and multiple episodes of hypotension were associated with higher risk of SAEs (general anesthesia: odds ratio [OR] 5.09, 95% confidence interval [CI] 1.96–13.24, P = 0.001; hypotension time: OR 4.29, 95% CI 1.66–11.10, P = 0.003). After the multidisciplinary implementation, the postoperative length of stay was decreased from 15 days to 10 days (P < 0.0001); incidence of SAEs was decreased from 21.1% to 7.0% (P = 0.002), and the all-cause mortality rate within 30 days decreased from 4.6% to 1.0% (P = 0.040). Our observational study demonstrated that an increasing application of general anaesthesia and longer time of hypotension were associated with an increased risk of postoperative SAEs in patients after THA or hemiarthroplasty. Additionally, optimizing stable haemodynamics under higher application of combined-spinal epidural anaesthesia was associated with improved outcome up to 30 days after THA or hemiarthroplasty.

Anesthetic management of geriatric patients

The number of elderly patients who frequently access health care services is increasing worldwide. While anesthesiologists are developing the expertise to care for these elderly patients, areas of concern remain. We conducted a comprehensive search of major international databases (PubMed, Embase, and Cochrane) and a Korean database (KoreaMed) to review preoperative considerations, intraoperative management, and postoperative problems when anesthetizing elderly patients. Preoperative preparation of elderly patients included functional assessment to identify preexisting cognitive impairment or cardiopulmonary reserve, depression, frailty, nutrition, polypharmacy, and anticoagulation issues. Intraoperative management included anesthetic mode and pharmacology, monitoring, intravenous fluid or transfusion management, lung-protective ventilation, and prevention of hypothermia. Postoperative checklists included perioperative analgesia, postoperative delirium and cognitive dysfunction, and other complications. A higher level of perioperative care was required for older surgical patients, as multiple chronic diseases often makes them prone to developing postoperative complications, including functional decline and loss of independence. Although the guiding evidence remains poor so far, elderly patients have to be provided optimal perioperative care through close interdisciplinary, interprofessional, and cross-sectional collaboration to minimize unwanted postoperative outcomes. Furthermore, along with adequate anesthetic care, well-planned postoperative care should begin immediately after surgery and extend until discharge.

Ultrasound-guided continuous fascia iliaca compartment block for pre-operative pain control in very elderly patients with hip fracture: A randomized controlled trial

The present study presented the results of a prospective, randomized controlled trial. The present study enrolled 98 very elderly patients with hip fractures, complicated with at least one cardiovascular, neurological or pulmonary disease, of whom 10 patients were excluded. A total of 88 patients were randomly assigned into 2 groups: i) The control group, receiving traditional analgesia including 50 mg Tramadol and 500 mg paracetamol orally three times a day from admission to surgery; and ii) the study group, receiving ultrasound-guided continuous fascia iliaca compartment block (CFICB), a single 50 ml 0.4% ropivacaine injection with continuous infusion of 0.2% ropivacaine at a dose of 5 ml/h from admission to surgery. The primary outcome measure of pain relief or pain intensity was assessed preoperatively and up to 48 h postoperatively using a visual analog scale (VAS). The results of the present study indicated that in the preoperative period, in the morning of the day of surgery, the VAS pain at rest scores were lower in the study group compared with the control group (P=0.023). The VAS passive movement scores of the study group were also significantly lower compared with the control group 1 h following analgesia at the time of admission (P<0.05) and in the morning of the day of surgery (P<0.05). Scores for patients' satisfaction with the analgesic regimen in the preoperative period were greater in the study group compared with the control group (P<0.001). There was no difference in analgesia-associated side effects between groups. Duration of hospital stay of patients in the control group was significantly longer compared with the study group (P=0.001). Patients in the study group were less likely to have increased complications compared with patients in the control group over the N2-N4 period (from preoperative period to after surgery; P=0.016). The present study concluded that ultrasound guided CFICB was an effective method of providing analgesia for very elderly (≥80 years old) with hip fracture.

Geriatric Anesthesia-related Morbidity and Mortality in China: Current Status and Trend

Objective:

The population of elderly patients and the amount of geriatric anesthesia have been growing rapidly in China. Thus, understanding the morbidity and mortality associated with geriatric anesthesia in China is critical to the improvement of anesthesia quality and outcome. The aim of the review was to discuss the geriatric anesthesia-related morbidity and mortality in China, as well as to point out the future trend.

Data Sources:

Articles in this review were all searched from Wanfang, China National Knowledge Infrastructure (CNKI), VIP, PubMed, and Web of Science databases, based on the reports originated in China from January 2011 to December 2016.

Study Selection:

A total of 57 studies were selected for further study, including 12 retrospective studies, 35 prospective studies, 3 meta-analyses, 4 reviews, 1 viewpoint, and 2 case reports. Of the total studies, 42 studies were in Chinese while 15 were in English.

Results:

The mortality and morbidity associated with geriatric anesthesia in China are not yet completely reported. Some factors have been recognized, while some are yet to be identified and confirmed. Several studies addressed postoperative cognitive dysfunction and postoperative delirium, whereas only a few studies can be found on renal complications. Thus, a nationwide registry is essential for geriatric anesthesia-associated adverse outcomes. The mortality associated with geriatric anesthesia in China should be reported promptly. In the future, the perspective of geriatric anesthesia needs to be expanded into perioperative geriatric medicine to improve the perioperative management strategy based on the postoperative outcome-directed concept transformation.

Conclusions:

Anesthesiologists should evaluate the physiological and medical status and focus on the prevention of potential complications in the perioperative setting with the goal to enhance elderly patients’ long-term well-being and survival quality.

Fascia iliaca compartment block versus no block for pain control after lower limb surgery: a meta-analysis

Background

The analgesic effect of fascia iliaca compartment block (FICB) versus no block (NB) after lower limb surgery (LLS) is still controversial, so we performed this meta-analysis.

Materials and methods

By searching the PubMed, Embase and the Cochrane Library (last update by July 20, 2017), randomized controlled trials comparing the analgesic effect of FICB versus NB in patients receiving LLS were identified. The primary outcome was the pain scores at 4, 12, and 24 h after LLS. The dosage of morphine at 24 h was also collected. The side effect of anesthesia was assessed according to the occurrence rate of postoperative nausea and vomiting.

Results

Data from 7 clinical trials that included 508 patients were summarized. The results showed that patients receiving FICB had lower pain scores at 4 h (mean difference [MD]=−1.17; 95% CI=−2.30 to −0.05; P=0.041), 12 h (MD=−0.41; 95% CI=−0.76 to −0.05; P=0.026) and 24 h (MD=−0.96; 95% CI=−1.77 to −0.15; P=0.020) after LLS. Besides, FICB could reduce the dosage of morphine at 24 h (MD=−2.06; 95% CI=−3.82 to −0.30; P=0.022) and the incidence of postoperative nausea and vomiting (relative risk rate=0.44, 95% CI=0.24–0.80, P=0.008).

Conclusion

Compared with NB, FICB is an effective and safe method for alleviating the pain after LLS. More high-quality randomized controlled trials are needed to confirm this finding.

Nerve Blocks in the Geriatric Patient With Hip Fracture: A Review of the Current Literature and Relevant Neuroanatomy

Introduction

Hip fracture is a common occurrence in the elderly population with high morbidity and mortality due to postoperative pain and opioid use. The goal of this article is to review the current literature on the neuroanatomy of the hip and the use of localized nerve block in controlling hip fracture pain.

Methods

A thorough search of MEDLINE/PubMed, Embase, and the Cochrane Database of Systematic Reviews was conducted using the search terms "hip fracture" and "fascia iliaca block (FICB)." An additional search was conducted utilizing multiple search terms including "hip fracture," "greater trochanter," "femur," "hip," "anatomy," "neuroanatomical," and "anatomic." Each search result was investigated for cadaveric studies on the innervation of the trochanteric region.

Results

Twenty-five clinical studies examining the use of FICBs in hip fracture patients were identified. These studies show that FICB is safe and effective in controlling perioperative pain. Additionally, FICB has been shown to decrease opioid requirement and opioid-related side effects. Neuroanatomical studies show that the hip capsule is innervated by contributions from the femoral, obturator, sciatic, and superior gluteal nerves. Imaging studies suggest that FICB anesthetizes these branches through localized spread along the fascia iliaca plane. Cadaveric evidence suggests that the greater trochanter region is directly innervated by a single branch from the femoral nerve.

Discussion

The proven efficacy of nerve blocks and their anatomic basis is encouraging to both the anesthesiologist and orthopedic surgeon. Their routine use in the hip fracture setting may improve patient outcomes, given the unacceptably high morbidity and mortality associated with opioid use.

Conclusions

Localized nerve blocks, specifically FICB, have been shown to be safe and effective in managing acute hip fracture pain in geriatric patients, leading to decreased opioid use. Knowledge of the hip neuroanatomy may help guide future development of hip fracture pain blockade.

Femoral nerve block versus fascia iliaca block for pain control in total knee and hip arthroplasty: A meta-analysis from randomized controlled trials

BACKGROUND

This meta-analysis aimed to perform a meta-analysis to compare the efficiency and safety between femoral nerve block (FNB) and fascia iliaca block (FIB) for postoperative pain control in patients undergoing total knee and hip arthroplasties.

METHODS

A systematic search was performed in Medline (1966-2017.05), PubMed (1966-2017.05), Embase (1980-2017.05), ScienceDirect (1985-2017.05) and the Cochrane Library. Inclusion criteria (1) Participants: Only published articles enrolling adult participants that with a diagnosis of end-stage of osteoarthritis and prepared for unilateral TKA or THA; (2) Interventions: The intervention group received FIB for postoperative pain management; (3) Comparisons: The control group was received FNB for postoperative pain control; (4) Outcomes: Visual analogue scale (VAS) scores in different periods, opioids consumption, length of stay and postoperative complications; (5) Study design: clinical randomized control trials (RCTs) were regarded as eligible in our study. Cochrane Hand book for Systematic Reviews of Interventions was used for assessment of the included studies and risk of bias was shown. Fixed/random effect model was used according to the heterogeneity tested by I2 statistic. Sensitivity analysis was conducted and publication bias was assessed. Meta-analysis was performed using Stata 11.0 software.

RESULTS

Five RCTs including 308 patients met the inclusion criteria. The present meta-analysis indicated that there were no significant differences between groups in terms of visual analog scale (VAS) score at 12 hours (SMD = -0.080, 95% CI: -0.306 to 0.145, P = .485), 24 hours (SMD = 0.098, 95% CI: -0.127 to 0.323, P = .393), and 48 hours (SMD = -0.001, 95% CI: -0.227 to 0.225, P = .993). No significant differences were found regarding opioid consumption at 12 hours (SMD = 0.026, 95% CI: -0.224 to 0.275, P = .840), 24 hours (SMD = 0.037, 95% CI: -0.212 to 0.286, P = .771), and 48 hours (SMD = -0.016, 95% CI: -0.265 to 0.233, P = .900). In addition, no significant increase of complications was identified between groups.

CONCLUSION

There is no significant differences of VAS scores at 12-48 hour and opioids consumption at 12-48 hour between two groups following total joint arthroplasty. No increased risk of nausea, vomiting and pruritus was observed in both groups. More high-quality large RCTs with long follow-up period are necessary for proper comparisons of the efficacy and safety of FNB with FIB. The present meta-analysis exists some limitations that should be noted: (1) Only five articles were included in present meta-analysis, although all of them are recently published RCTs, the sample size are relatively small; (2) Functional outcome is an important parameter, due to the insufficiency of relevant data, we cannot perform a meta-analysis. (3) Dose and types of local anesthetics are varied, which may influence the results; (4) The duration of follow up is relatively short which leads to underestimating complications. (5) Publication bias in present meta-analysis may influence the results.

The efficiency and safety of fascia iliaca block for pain control after total joint arthroplasty: A meta-analysis

BACKGROUND

This meta-analysis aimed to perform a meta-analysis including randomized controlled trials (RCTs) to assess the efficiency and safety of fascia iliaca block (FIB) for pain control in patients undergoing total joint arthroplasty (TJA).

METHODS

A systematic search was performed in Medline (1966-2017.03), PubMed (1966-2017.03), Embase (1980-2017.03), ScienceDirect (1985-2017.03) and the Cochrane Library. Study evaluated the efficiency and safety of FIB in TJA was selected. Meta-analysis was performed using Stata 11.0 software.

RESULTS

Five randomized controlled trials (RCTs) including 270 patients met the inclusion criteria. The present meta-analysis indicated that there were significant differences between groups in terms of visual analog scale (VAS) score at 12 hours (SMD = -0.544, 95% CI: -0.806 to -0.281, P = .000) and 24 hours (SMD = -0.519, 95% CI: -0.764 to -0.273, P = .000), morphine equivalent consumption at 12 hours (SMD = -0.895, 95% CI: -1.164 to -0.626, P = .000) and 24 hours (SMD = -0.548, 95% CI:-0.793 to -0.303, P = .000). In addition, fewer adverse side effect was identified in FIB groups (RD = -0.139, 95% CI: -0.243 to -0.034, P = .009).

CONCLUSION

The application of fascia iliaca block could significantly reduce VAS scores and morphine consumption at 12 and 24 hours following total knee and hip arthroplasty. In addition, there were fewer adverse effects in FIB groups. Due to the limited quality of the evidence currently available, higher quality RCTs are required.
