The Fascia Iliaca Block as the Primary Intraoperative Anesthesia for Hip Fracture Surgery: A Preliminary Study

Reoperation Rate of Internal Fixation for Femoral Neck Fractures in the Elderly - A Retrospective Follow-Up Study in 116 Patients With an Exploration of Risk Factors

Aim

Internal fixation of femoral neck fractures is a widely used procedure that is comparatively less invasive and faster than hip replacement. While head preserving internal fixation of these fractures are still preferred where feasible, a faster recovery and lower reoperation rates make arthroplasty increasingly more appealing, in spite of being a more invasive option. Our aim was to determine the reoperation rate after internal fixation at our institution and to explore relevant risk factors in a geriatric population.

Methods

This monocentric follow-up study was conducted analyzing 116 patients aged 65 and older with femoral neck fractures who were surgically treated with either cancellous screws or dynamic hip screws between 2010 and 2017. We retrospectively collected longitudinal data from our patient database, supplemented by a telephone survey, with a follow-up period of at least 18 months.

Results

Twenty reoperations, due to either a failure of fixation, avascular necrosis, or posttraumatic osteoarthritis, were identified in our cohort, which constituted a reoperation rate of 17.2% (20/116). Fracture displacement was significantly associated with the reoperation risk (HR 8, CI 3-20; P < .001). The reoperation rate was 52.2% in displaced fractures vs 8.9% in undisplaced fractures. No link was found between the reoperation rate and gender, age, BMI, ASA score, type of implant, quality of internal fixation, type of living accommodation, and pre-fracture mobility.

Conclusion

Internal fixation has been found to be an effective option in elderly patients with undisplaced fractures regardless of their specific age, cognitive ability or physical condition. In displaced fractures the reoperation rate was found to be high, therefore a primary hip replacement should be recommended.

Evaluation of haemodynamic stability with the fascia iliaca compartment block in the elderly undergoing hip surgeries

Background and Aims:

Elderly patients with hip fracture have a high anaesthetic risk. Peri-operative management poses a challenge requiring a multi-disciplinary approach. This study investigated whether the fascia iliaca compartment block (FICB) with general anaesthesia (GA) using a supra-glottic device (SGD) can provide adequate analgesia and peri-operative haemodynamic stability and avoid post-operative complications.

Methods:

This prospective observational cross-sectional study was conducted after Institutional Review Board clearance and written informed consent of 30 patients of the American Society of Anesthesiologists grade II and III, undergoing elective surgery for fracture neck femur fracture, were obtained. After pre-medicating patients with inj. Glycopyrrolate and Midazolam, ultra-sonography (USG)-guided FICB was given in the supine position with a high-frequency linear probe using 30 ml of 0.25 % bupivacaine with 8 mg dexamethasone. After confirming the effect of the block at 20 min, patients were given GA with inj. Propofol and proper size I-gel was placed, and patients were maintained on oxygen, nitrous oxide, and sevoflurane.

Results:

FICB with GA using an SGD provides peri-operative haemodynamic stability with minimal changes in mean blood pressure and a heart rate with p value < 0.05. The visual analogue scale (VAS) score before giving the block was 9.5 ± 0.5, which decreased to 2.7 ± 0.49 at 20 min after giving the block, which was statistically significant. The post-operative duration of analgesia was 456 ± 43.438 min.

Conclusion:

Elderly patients with fracture neck femur often have one or more co-morbidities. In such patients, FICB with GA using an SGD is a useful technique providing peri-operative haemodynamic stability and satisfactory post-operative analgesia.

Monitored Anesthesia Care and Soft-Tissue Infiltration With Local Anesthesia: An Anesthetic Option for High-Risk Patients With Hip Fractures

OBJECTIVES

To examine the feasibility of a novel anesthetic option for hip fracture fixation with short cephalomedullary nails.

DESIGN

Retrospective cohort study.

SETTING

The study setting involved an urban, academic Level 1 trauma center, a tertiary care academic medical center, and an orthopaedic specialty hospital.

PATIENTS/PARTICIPANTS

Twenty recent and 40 risk-matched (1:1:1 by anesthesia type) historical hip fracture patients were included in the study.

INTERVENTION

All patients with an OTA/AO 31.A1-3 intertrochanteric hip fracture presenting from October 1, 2019 to March 31, 2020 treated with a short cephalomedullary nail underwent a new intraoperative anesthesia protocol using monitored anesthesia care (MAC) and soft-tissue infiltration with local anesthesia (STILA).

MAIN OUTCOME MEASUREMENTS

Intraoperative measures, postoperative pain scores, narcotic and acetaminophen use, hospital quality measures, and inpatient cost.

RESULTS

A total of 60 patients (20 each: MAC, general, and spinal) were identified. There were differences among the groups regarding mean minimum and maximum intraoperative heart rate with MAC-STILA protocol demonstrating the best maintenance of normal heart rate parameters (60-100 beats per minute). For the first 3 hours postoperatively, MAC-STILA patients reported consistently lower pain scores (visual analog scale <1) than spinal or general patients (visual analog scale > 1). Through 48 hours postoperatively, MAC-STILA narcotic usage was similar to that of the spinal cohort and approximately 5 times less than the general cohort. There were no differences in procedural time, length of stay, minor or major complications, inpatient and 30-day mortality, or 30-day readmissions, or postoperative ambulatory distance. There was no difference in inpatient cost among cohorts.

CONCLUSIONS

This feasibility study demonstrates safety for the MAC-STILA protocol with comparison to spinal and general anesthesia. The MAC-STILA protocol is a viable option for treatment of OTA/AO 13.A1-3 intertrochanteric fractures with a short cephalomedullary nail and may be the preferred method for patients with severe medical comorbidities or relative contraindications to general and/or spinal anesthesia.

Fascia Iliaca Block as an Anesthetic Technique for: Acute Lower Limb Ischemia

Purpose

The purpose of this study is to evaluate the efficacy of preoperative fascia iliaca block (FIB) as a sole anesthetic technique in transfemoral thromboembolectomy of unilateral acute lower limb ischemia compared to unilateral spinal anesthesia (SA) as a primary outcome. Hemodynamic variation, postoperative pain score, and the first demand for analgesia with the total postoperative analgesic required in the 1^st postoperative day were considered as the secondary outcome.

Patients and Methods

This prospective randomized controlled study included two groups of patients aged between 40 and 70 years, who underwent transfemoral thrombectomy for acute unilateral lower limb ischemia. Patients in the spinal group (SA) (n = 56): underwent unilateral SA using 10 mg bupivacaine 0.5% and patients in the group FIB (n = 56): received FIB with 30 mL of 0.25% bupivacaine. Sensory block was evaluated over the incisional area with 3-point scale. If the sensory block did not reach zero grade after 30 min, the patient received general anesthesia.

Results

The incidence of the successful block was 100% in the SA group compared to 80.35% in the FIB group. There was a significant decrease in recorded heart rate and mean blood pressure within the SA group at 3, 10, and 20 min and 3, 20, and 45 min, respectively. Values of visual analog scale decreased significantly in SA group compared to that of the FIB group immediately and 1 h postoperative. However, the time for the first postoperative analgesic requirement and morphine consumption was comparable between the groups.

Conclusion

Preoperative FIB could be considered as a promising alternative anesthetic technique to SA with better hemodynamic parameters in patients undergoing transfemoral thrombectomy for acute lower limb ischemia. It could be also due to limited precautions considered the first choice over SA for patients on perioperative anticoagulants.

Fascia Iliaca Compartment Block Efficacy in Resource-poor Emergency Departments

Introduction

Although the fascia iliaca compartment block (FICB) seems to be an ideal technique for femoral neck and shaft fractures occurring in resource-poor settings, it has been unclear how effective it is when used by emergency physicians (EP) with little training in the technique, using equipment, medications and methods that differ from those commonly available in developed countries. This series was designed to demonstrate that EPs in a resource-poor setting can provide effective analgesia for femur fractures with anatomic landmark-guided FICBs, clinician-compounded lidocaine-epinephrine (1:100,000), and a standard injection needle.

Methods

Over a three-month period, patients ≥12 years old presenting to the emergency department with hip or femur fractures and a Likert visual analogue scale >4 had an EP-administered FICB. EPs used a standard intramuscular needle and a lidocaine-epinephrine solution they compounded at the bedside and located the injection site using only anatomic landmarks. EPs evaluated the patient’s pain level at 30 minutes and at two hours post-FICB. We also reviewed articles since 2016 that describe the FICB.

Results

We enrolled a non-consecutive sample of 10 patients in the case series. Five had femoral neck (hip) fractures and five had femoral shaft fractures. All patients had a reduction in their pain levels after the FICB. On average, the block took effect about three minutes after injection. At 30 minutes all patients reported clinically meaningful pain reduction. The analgesic effect of the compounded agent lasted approximately 200 minutes. No adverse effects were reported. No published journal articles about FICB since 2016 were from resource-poor settings, and only one was from a developing country.

Conclusion

This series suggests that the FICB is effective even when performed with the minimal materials that are usually available in resource-poor settings. Methods such as this, which use simplified clinical tests and techniques applicable in resource-poor settings, can assist global emergency medicine (EM). We can assist global EM by similarly finding methods to simplify useful clinical tests and techniques that can be used in resource-poor settings.
