Enhanced recovery after surgery pathway: The use of fascia iliaca blocks causes delayed ambulation after total hip arthroplasty

Regional anaesthesia: what surgical procedures, what blocks and availability of a “block room”?

PURPOSE OF REVIEW

With an expected rise in day care procedures with enhanced recovery programs, the use of specific regional anaesthesia can be useful. In this review, we will provide insight in the used regional block and medication so far known and its applicability in a day care setting.

RECENT FINDINGS

Regional anaesthesia has been improved with the aid of ultrasound-guided placement. However, it is not commonly used in the outpatient setting. Old, short acting local anaesthetics have found a second life and may be especially beneficial in the ambulatory setting replacing more long-acting local anaesthetics such as bupivacaine.To improve efficiency, a dedicated block room may facilitate the performance of regional anaesthesia. However, cost-efficacy for improved operating time, patient care and hospital efficiency has to be established.

SUMMARY

Regional anaesthesia has proven to be beneficial in ambulatory setting. Several short acting local anaesthetics are favourable over bupivacaine in the day care surgery. And if available, there are reports of the benefit of an additional block room used in a parallel (monitored) care of patients.

The continuous infusion fascia iliaca compartment block: a safe and effective analgesic modality in geriatric hip fracture patients

OBJECTIVE

Hip fractures are common orthopaedic injuries in the elderly. Opioids can provide peri-operative pain relief in hip fracture patients, but may have side effects. Peripheral nerve blocks such as the fascia iliaca compartment block (FICB) have become an established part of the multimodal analgesic regime administered peri-operatively to hip fracture patients. We compare the efficacy of the continuous infusion FICB (CFICB) on peri-operative pain relief, opioid usage, its associated complications and the short as well as long term rehabilitation status in geriatric hip fractures patients.

MATERIALS AND METHODS

In this retrospective matched case control study, 40 geriatric patients with hip fractures who had received the CFICB from Nov 2014 to April 2016 were matched in a 1:3 ratio with similar patients whom had not received the CFICB from our institution's hip fracture database of 913 patients.

RESULTS

A total of 157 patients in both the CFICB group (N = 40) and the control group (N = 117) were studied. The post-operative pain scores and the total opioid consumption during the first 3 days in the CFICB group were significantly less than the control group (p < 0.0001, respectively). The systemic complications in the CFICB group were comparable with the control group. The CFICB group had slower rehabilitation at up to 2 weeks but there was no significant difference at 1 year post surgery in terms of function and mobility between the two groups. In both groups, better pre-fracture function was associated with faster short term rehab outcomes in post-operative patients.

CONCLUSION

The CFICB provides safe and effective post-operative pain relief in geriatric hip fracture patients. Post-operative opioid usage is decreased in older hip fracture patients treated with CFICB. Rehabilitation milestones are slower in the short term, but have no significant difference at 1-year post surgery.

Pain Control After Total Hip Arthroplasty: A Randomized Controlled Trial Determining Efficacy of Fascia Iliaca Compartment Blocks in the Immediate Postoperative Period

BACKGROUND

The purpose of this randomized controlled trial is to identify if a fascia iliaca block reduces postoperative pain and narcotic consumption and improves early functional outcomes in primary total hip arthroplasty (THA) performed through the mini-posterior approach.

METHODS

Patients were recruited from September 2017 to September 2019. Eligible patients received a primary THA using a mini-posterior approach with epidural anesthesia. Postoperatively, patients were randomized to receive a fascia iliaca compartment block or a placebo block. Numeric Rating Scale pain scores, narcotic consumption, and functional outcomes were recorded at regular intervals postoperatively.

RESULTS

Upon study completion, 122 patients were available for final analysis. There was no difference in the average pain scores at any time interval between the placebo and block groups during the first 24 hours (P = .21-.99). There was no difference in the morphine equivalents consumed between the groups during any time interval postoperatively (P = .06-.95). Functional testing showed no difference in regards to distance walked during the first therapy session (67.1 vs 68.3 ft., P = .92) and timed-up-and-go testing (63.7 vs 66.3 seconds, P = .86). There was an increased incidence of quadriceps weakness in the block group (22% vs 0%, P = .004) requiring alterations in therapy protocols.

CONCLUSION

This randomized trial shows that a fascia iliaca compartment block does not improve functional performance and does not decrease pain levels or narcotic usage after mini-posterior THA, but does increase the risk of quadriceps weakness postoperatively. Based on these results we do not recommend routine fascia iliaca compartment blocks after THA performed with the mini-posterior approach.
