Ultrasound-guided Lumbar Erector Spinae Plane Block For Postoperative Analgesia in Femur Fracture: A Pediatric Case Report

Postoperative analgesic effect of lumbar erector spinae plane block for developmental hip dysplasia surgery: a randomized controlled double-blind study

Open surgery for developmental dysplasia of the hip (DDH) may cause severe pain due to tenotomies and pelvic-femoral osteotomies. This study aims to evaluate the analgesic effect of ultrasound-guided Lumbar Erector Spina Plane (L-ESP) Block in pediatric patients undergoing DDH surgery. Sixty children scheduled for DDH surgery were randomly assigned into two groups. Group I (n = 30) received L-ESP with 0.5 mL/kg of 0.25% bupivacaine before surgery. In contrast, Group II (n = 30), as the control group, received the same volume of saline injection. Identical postoperative analgesia protocol was adjusted for both groups. Parental satisfaction, pain levels, ibuprofen, and opioid consumption were recorded. Pain levels were evaluated with the FLACC (Face, Legs, Activity, Crying, Consolability) scale. FLACC scores at the first 24th hours were lower in the L-ESP group than the control group (p < 0.001). Rescue opioid utilization was higher in the control group (15/26) than in the L-ESP group (2/29) (p < 0.001). The consumption of ibuprofen was higher in the control group than in the L-ESP group in the ward (24/26 vs. 3/29, p < 0.001, respectively). Parental satisfaction was superior in the L-ESP group (p = 0.024). To provide postoperative analgesia for DDH surgery, ultrasound-guided L-ESP may be an effective and alternative regional anesthetic technique.

Continuous Ultrasound-Guided Lumbar Erector Spinae Plane Block for Thigh Cellulitis Analgesia: A Case Report

The management of refractory acute medical pain can be challenging, especially if severe and decompensated systemic pathologies contraindicate neuraxial techniques and deep peripheral blocks. In this case report, we propose a continuous ultrasound-guided lumbar erector spinae plane block (ESPB) for multimodal analgesia of thigh cellulitis. The patient was an 80-year-old male, admitted to the intensive care unit due to septic shock originating from cellulitis of the right lower limb, associated with multiorgan dysfunction. To address refractory pain in the thigh, an ultrasound-guided lumbar ESPB at L3 was performed, with the placement of a perineural catheter and administration of 30 mL of 0.5% ropivacaine, followed by 30 mL boluses of 0.375% ropivacaine every six hours with progressive weaning. The patient maintained controlled pain without the need for rescue analgesia. Continuous ultrasound-guided lumbar ESPB is an effective and safe alternative for thigh analgesia in patients with refractory acute medical pain and systemic pathologies that contraindicate other regional techniques.

Lumbar Erector Spinae Plane Block for Dega Pelvic Osteotomy in a Pediatric Patient With Complex Neurological Issues: A Case Report

The erector spinae plane (ESP) block, initially designed for thoracic analgesia, has evolved into a versatile regional anesthesia technique with literature support for success in numerous contexts. In this case report, we highlight the successful application of ESP to provide postoperative analgesia for pediatric Dega osteotomy involving both the femoral head and acetabulum, in a patient with numerous neurological comorbidities that would have weighed against some more traditional regional anesthesia techniques. This case further highlights the versatility of ESP, demonstrating its use in blocking lumbar nerve roots in a pediatric patient with complex neurological challenges.

Regional anesthesia for pain control in children with solid tumors-a review of case reports

Introduction

Around seventy percent of all childhood cancer patients suffer from severe pain. This pain can arise from various sources, including tumors themselves, pain caused by metastasizing tumor cells or as the outcome of therapy meant to deal with tumors. If managed inadequately, such pain can lead to many hazardous sequelae. However, there are extreme cases when pain does not respond to standard treatment. For such cases, regional anesthesia or nerve blocks are utilized as the utmost pain control measure. Blocks are used to treat pain in patients who no longer respond to conventional opioid-based treatment or whose worsened condition makes it impossible to receive any other therapy. The data regarding the use of regional anesthesia for such cases in the children population is limited.

Methods

For this review we searched for case reports in Scopus and PubMed from inception to 2023. The descriptive search items included terms related to childhood cancer and the description of each block. The inclusion criteria for review include children (0-18 years old) receiving oncology-related surgical procedures or palliative care. The data collection was limited to solid tumor-related cases only. We analyzed a total of 38 studies that included case reports and one retrospective study.

Results and discussion

It was concluded that nerve blocks, although rarely performed, are a safe and efficient way of pain control in children with solid tumors. The major settings for block performance are postoperative pain control and palliative care. We observed that block indication and its outcomes depend on unique health circumstances in which they should be performed. Patients with similar diagnoses had differing outcomes while receiving the same block treatment.

Ultrasound-guided lumbar erector spinae plane block versus caudal block for postoperative analgesia in pediatric hip and proximal femur surgery: a randomized controlled study

BACKGROUND

According to previous research, 20% of infants experience prolonged postsurgical pain 6-12 months after major surgery, which is linked to functional impairment and a lower quality of life. The aim of our study is to evaluate whether the analgesic effect of the erector spinae plane block (ESPB) is superior to that of caudal epidural anesthesia (CEA) in pediatric patients undergoing hip or proximal femoral surgeries.

METHODS

Seventy-six children ranging in age from 1 to 7 years scheduled for hip or proximal femur surgery were randomly assigned to receive either a unilateral ultrasound-guided ESPB or CEA with bupivacaine 0.25% at a dose of 0.5 ml/kg. The primary outcome was the Face, Legs, Activity, Cry, and Consolability (FLACC) scale 2 h postoperatively. The secondary outcomes were pain scores every 15 min for the first hour and then at 6, 12, and 24 h postoperatively; the block failure rate; time to perform a successful block; and time to first rescue analgesia.

RESULTS

The FLACC score 2 h post¬operatively was not superior in the ESPB group compared to the CEA group; indeed, it was significantly higher in the ESPB group at 15 and 30 min post-operation (P = 0.005, 0.004, respectively). Additionally, the time to first rescue analgesia was prolonged in the CEA group (P < 0.001). The time to perform a successful block was comparable between the groups.

CONCLUSIONS

The analgesic effect of the ESPB was not superior to that of CEA in pediatric patients undergoing hip and proximal femur surgery.

Erector spinae plane block in children: a narrative review

The erector spinae plane block (ESPB) is a novel technique used in both adult and pediatric patients. Its use in children has mostly been described in terms of perioperative pain management for various types of surgery. After its introduction, anesthesiologists began using ESPBs in various surgical settings. As adequate analgesia along with a low complication rate were reported, interest in this technique dramatically increased. Many studies in adults and children, including randomized controlled trials, have been published, resulting in the emergence of different clinical indications, with various technical and pharmacological approaches currently evident in the literature. This narrative review aims to analyze the current evidence in order to guide practitioners towards a more homogeneous approach to ESPBs in children, with a major focus on clinical applications. The ESPB is an efficient, safe, and relatively easy technique to administer. It can be applied in a wide range of surgeries, includes thoracic, abdominal, hip, and femur surgery. Its usefulness is evident in the context of enhanced recovery after surgery protocols and multimodal analgesia. Single-shot, intermittent bolus, and continuous infusion techniques have been described, and non-inferiority has been observed when compared with other locoregional techniques. Even though both the efficacy and safety of the procedure are widely accepted, current evidence is predominantly based on case reports, with very few well-designed observational studies. Consequently, the level of evidence is still poor, and more well-designed double-blind, randomized, placebo-controlled trials are needed to refine the procedure for different clinical applications in the pediatric population.

The Effect of Ultrasound-Guided Erector Spinae Plane Block versus Thoracic Epidural Block on Postoperative Analgesia After Nuss Surgery in Paediatric Patients: Study Protocol of a Randomized Non-Inferiority Design Trial

Purpose

The Nuss procedure is a recognized treatment for adolescent pectus excavatum that results in severe postoperative pain. Erector spinae plane block (ESPB) is a novel technique that provides postoperative analgesia and reduces opioid consumption. Our aim is to explore whether ESPB produces analgesia similar to thoracic epidural anaesthesia (TEA) in paediatric patients undergoing Nuss procedure.

Study Design and Methods

This randomized, controlled, non-inferiority trial will enrol 300 paediatric patients undergoing Nuss surgery. Participants will be randomly assigned 1:1 to receive ESPB or TEA preoperatively. The primary, joint endpoint is the average numeric rating scale (NRS) score and cumulative sufentanil consumption. The secondary endpoints are pain scores and sufentanil consumption at different time points after surgery, analgesia-related side effects, and other postoperative complications. Data will be analysed by the intention-to-treat principle.

Discussion

This study investigates the effect of ESPB on postoperative opioid consumption and pain scores and intend to provide a new strategy of analgesia management for Nuss procedure in paediatric patients.

ERECTOR SPINAE PLANE BLOCK AND PLACEMENT OF PERINEURAL CATHETER FOR DEVELOPMENTAL HIP DISORDER SURGERY IN CHILDREN

The ultrasound-guided erector spinae plane (ESP) block is a novel interfascial plane block technique providing analgesic effects in different localizations of the body, in accordance with the level of administration. Although ESP block is usually performed in the thoracic region in pediatric patients, it is possible to achieve ESP block in the lumbar region as well. Postoperative pain management is essential in patients undergoing operative hip treatment, one of the most common procedures in pediatric orthopedic surgery. We report on a case of effective intraoperative analgesia achieved by ultrasound-guided lumbar ESP block and another case of effective intra- and postoperative analgesia accomplished with perineural catheter placement in addition to lumbar ESP block, both performed in children surgically treated for developmental hip disorders.

A cadaveric study of the erector spinae plane block in a neonatal sample

Background

The aim of this article was to provide a detailed description of the neonatal anatomy related to the erector spinae plane block and to report the spread of the dye within the fascial planes and potential dermatomal coverage.

Methods

Using ultrasound guidance, the bony landmarks and anatomy of the erector spinae fascial plane space were identified. The erector spinae plane block was then replicated unilaterally in two fresh unembalmed neonatal cadavers. Using methylene blue dye, the block was performed at vertebral levels T5—using 0.5 mL in cadaver 1—and T8—using 0.2 mL in cadaver 2. The craniocaudal spread of dye was tracked within the space on the ultrasound screen and further confirmed on dissection.

Results

Craniocaudal spread was noted from vertebral levels T3 to T6 when the dye was introduced at vertebral level T5 and from vertebral levels T7 to T11 when the dye was introduced at vertebral level T8. Furthermore, the methylene blue spread was found anteriorly in the paravertebral and epidural spaces, staining both the dorsal and ventral rami of the spinal nerves T2 to T12. Small amounts of dye were also found in the intercostal spaces.

Conclusion

In two neonatal fresh cadavers, the dye was found to spread to multiple levels and key anatomic locations.
