The impact of fascia iliaca compartment block on chronic postsurgical pain in patients undergoing hip fracture repair

Peripheral Nerve Blocks in the Preoperative Management of Hip Fractures: A Systematic Review and Network Meta-Analysis

STUDY OBJECTIVE

We conducted a systematic review and network meta-analysis to evaluate the comparative efficacy of peripheral nerve block types for preoperative pain management of hip fractures.

METHODS

We searched Cochrane, Central Register of Controlled Trials, MEDLINE, EMBASE, ICTRP, ClinicalTrials.gov, and Google Scholar for randomized clinical trials. We included participants aged more than 16 years with hip fractures who received peripheral nerve blocks or analgesics for preoperative pain management. The primary outcomes were defined as absolute pain score 2 hours after block placement, preoperative consumption of morphine equivalents, and length of hospital stay. We used a random-effects network meta-analysis conceptualized in the Bayesian framework. Confidence of evidence was assessed using Confidence in Network Meta-Analysis (CINeMA).

RESULTS

We included 63 randomized controlled studies (4,778 participants), of which only a few had a low risk of bias. The femoral nerve block, 3-in-1 block, fascia iliaca compartment block, and pericapsular nerve group block yielded significantly lowered pain scores at 2 hours after block placement compared with those with no block (standardized mean differences [SMD]: -1.1; 95% credible interval [CrI]: -1.7 to -0.48, [confidence of evidence: low]; SMD: -1.8; 95% CrI: -3.0 to -0.55, [low]; SMD: -1.4; 95% CrI: -2.0 to -0.72, [low]; SMD: -2.3; 95% CrI: -3.2 to -1.4, [moderate], respectively). The pericapsular nerve group block, 3-in-1 block, fascia iliaca compartment block, and femoral nerve block resulted in lower pain scores than the no-block group. Additionally, the pericapsular nerve group block yielded a lower pain score than femoral nerve block or fascia iliaca compartment block (SMD: -1.21; 95% CrI: -2.18 to -0.23, [very low]: SMD: -0.92; 95% CrI: -1.70 to -0.16, [low]). However, both the fascia iliaca compartment block and femoral nerve block did not show a reduction in morphine consumption compared with no block. To our knowledge, no studies have compared the pericapsular nerve group block with other methods regarding morphine consumption. Furthermore, no significant difference was observed between peripheral nerve blocks and no block in terms of the length of hospital stay.

CONCLUSIONS

Compared with no block, preoperative peripheral nerve blocks for hip fractures appear to reduce pain 2 hours after block placement. Comparing different blocks, pericapsular nerve group block might be superior to fascia iliaca compartment block and femoral nerve block for pain relief, though the confidence evidence was low in most comparisons because of the moderate to high risk of bias in many of the included studies and the high heterogeneity of treatment strategies across studies. Therefore, further high-quality research is needed.

General practice management of chronic post-surgical pain in patients with hip fracture: a qualitative study

Background

Hip fractures are common among elderly people and often lead to chronic post-surgical pain (CPSP). Effective CPSP management when patients transition from hospital to community settings is essential, but has not been sufficiently researched. This study examined general practitioner (GP) perspectives on managing patients with CPSP after hip fractures in Shanghai, China.

Methods

A descriptive qualitative study was performed wherein semi-structured interviews were conducted with GPs practicing in Shanghai who volunteered to participate. This study was initiated after a regional survey of general practice care for patients with CPSP following hip fracture.

Results

Six key themes emerged: (1) GPs' care priorities for patients with CPSP varied; (2) pharmacological management posed challenges in terms of selecting appropriate medications; (3) consultation time constraints hindered comprehensive management; (4) GPs desired better communication from hospitals at discharge; (5) limited access to services, such as pain specialists and allied health, obstructed optimal care delivery; and (6) patient nonadherence to CPSP treatment was an issue.

Conclusion

Multiple patient-, provider-, and system-level factors affected GP care for patients with CPSP after hip fracture. Improved interdisciplinary communication and education on evidence-based CPSP guidelines are needed to address the knowledge gaps among GPs. Barriers to healthcare access must be minimized to facilitate guideline-based care.

Effects of Intraoperative Local Pain Cocktail Injections on Early Function and Patient-Reported Outcomes: A Randomized Controlled Trial

OBJECTIVE

To determine whether a perioperative pain cocktail injection improves postoperative pain, ambulation distance, and long-term outcomes in patients with hip fracture.

DESIGN

Prospective, single-blinded, randomized controlled trial.

SETTING

Academic Medical Center.

PATIENTS/PARTICIPANTS

Patients with OTA/AO 31A1-3 and 31B1-3 fractures undergoing operative fixation, excluding arthroplasty.

INTERVENTION

Multimodal local injection of bupivacaine (Marcaine), morphine sulfate (Duramorph), ketorolac (Toradol) given at the fracture site at the time of hip fracture surgery (Hip Fracture Injection, HiFI).

MAIN OUTCOME MEASUREMENTS

Patient-reported pain, American Pain Society Patient Outcome Questionnaire (APS-POQ), narcotic usage, length of stay, postoperative ambulation, Short Musculoskeletal Function Assessment.

RESULTS

Seventy-five patients were in the treatment group and 109 in the control group. Patients in the HiFI group had a significant reduction in pain and narcotic usage compared with the control group on postoperative day (POD) 0 ( P < 0.01). Based on the APS-POQ, patients in the control group had a significantly harder time falling asleep, staying asleep, and experienced increased drowsiness on POD 1 ( P < 0.01). Patient ambulation distance was greater on POD 2 ( P < 0.01) and POD 3 ( P < 0.05) in the HiFI group. The control group experienced more major complications ( P < 0.05). At 6-week postop, patients in the treatment group reported significantly less pain, better ambulatory function, less insomnia, less depression, and better satisfaction than the control group as measured by the APS-POQ. The Short Musculoskeletal Function Assessment bothersome index was also significantly lower for patients in the HiFI group, P < 0.05.

CONCLUSIONS

Intraoperative HiFI not only improved early pain management and increased ambulation in patients undergoing hip fracture surgery while in the hospital, it was also associated with early improved health-related quality of life after discharge.

Chronic pain after surgery and trauma: current situation and future directions

Chronic post-surgical pain (CPSP) stands as a major health issue. The unchanged incidence over the last two decades underlines both the failure of predictive models developed until now and the lack of efficacy of common “preventive” strategies (pharmacotherapy and regional analgesic techniques) applied in current clinical practice. The recognition of CPSP as a disease and the release of a common definition of the condition is an important progress in the field. CPSP predictive scores exist but none has presently demonstrated an impact on patient care. New clinical directions based on the resolution of postoperative pain, a complex and highly dynamic process supported by individual pain trajectories, argue for predictive models and preventive strategies extended to the subacute pain period i.e. after hospital discharge.

Ultrasound-guided peripheral nerve blocks for preoperative pain management in hip fractures: a systematic review

Systematic reviews associate peripheral nerve blocks based on anatomic landmarks or nerve stimulation with reduced pain and need for systemic analgesia in hip fracture patients. We aimed to investigate the effect of ultrasound-guided nerve blocks compared to conventional analgesia for preoperative pain management in hip fractures. Five databases were searched until June 2021 to identify randomised controlled trials. Two independent authors extracted data and assessed risk of bias. Data was pooled for meta-analysis and quality of evidence was evaluated using Grades of Recommendation Assessment, Development and Evaluation (GRADE). We included 12 trials (976 participants) comparing ultrasound-guided nerve blocks to conventional systemic analgesia. In favour of ultrasound, pain measured closest to two hours after block placement decreased with a mean difference of -2.26 (VAS 0 to 10); (p < 0.001) 95% CI [–2.97 to –1.55]. In favour of ultrasound, preoperative analgesic usage of iv. morphine equivalents in milligram decreased with a mean difference of –5.34 (p=0.003) 95% CI [–8.11 to –2.58]. Time from admission until surgery ranged from six hours to more than three days. Further, ultrasound-guided nerve blocks may be associated with a lower frequency of delirium: risk ratio 0.6 (p = 0.03) 95% CI [0.38 to 0.94], fewer serious adverse events: risk ratio 0.33 (p = 0.006) 95% CI [0.15 to 0.73] and higher patient satisfaction: mean difference 25.9 (VAS 0 to 100) (p < 0.001) 95% CI [19.74 to 32.07]. However, the quality of evidence was judged low or very low. In conclusion, despite low quality of evidence, ultrasound-guided blocks were associated with benefits compared to conventional systemic analgesia.

From emergency department to operating room: interventional analgesia techniques for hip fractures

PURPOSE OF REVIEW

To provide an update on pain management options with regional anesthesia for patients with hip fractures at the emergency department (ED).

RECENT FINDINGS

Patients who sustain a hip fracture are typically admitted and diagnosed in the ED before being transferred to the operating room for surgery. Studies have clearly demonstrated the ability of the fascia iliaca compartment blocks (FICBs) and femoral nerve blocks (FNBs) to reduce pain and the risk of an acute confusional state. Their administration at an early stage of the patient's trajectory in the ED is beneficial. Recent anatomical studies contributed new knowledge of nociception in the hip joint, which allowed the development of more specific infiltration analgesia techniques without muscle weakness (e.g., pericapsular hip blocks). Further research on the timing of nerve blocks and an evaluation of new motor sparing techniques is indicated.

SUMMARY

FICB and FNB are established and recommended techniques in pain management for hip fracture patients. Their use early on in the ED may improve patient comfort and outcome. Pericapsular nerve hip blocks could provide a relevant alternative in future pain management in this group of patients.

Fascia Iliaca Compartment Block for Perioperative Pain Management of Geriatric Patients with Hip Fractures: A Systematic Review of Randomized Controlled Trials

Background

With continuous increase of the aging population, the number of geriatric patients with fragility hip fractures is rising sharply, and timely surgery remains the mainstay of treatment. However, adequate and effective pain control is the precondition of satisfactory efficacy. This systematic review aimed to summarize the use of fascia iliaca compartment block (FICB) as an analgesic strategy for perioperative pain management in geriatric patients with hip fractures.

Methods

PubMed and Embase databases were searched for English published randomized controlled trials (RCTs) reporting application of FICB for pain control of the older adults with hip fractures between January 1^st, 2000, and May 31^st, 2020. The modified Jadad scale was used to evaluate quality of the RCTs included. Primary outcomes of the eligible RCTs were presented and discussed.

Results

A total of 27 RCTs with 2478 cases were included finally. The present outcomes suggested, after admission or in the emergency department (ED), FICB can provide patients with equal or even better pain relief compared with the conventional analgesia methods, which can also reduce additional analgesic consumptions. While, before positioning for spinal anesthesia (SA), FICB is able to offer superior pain control, facilitating SA performance, after surgery FICB can effectively alleviate pain with decreased use of additional analgesics, promoting earlier mobilization and preventing complications.

Conclusions

FICB is a safe, reliable, and easy-to-conduct technique, which is able to provide adequate pain relief during perioperative management of geriatric patients with hip fractures.
