Background:
An erector spinae plane block is a relatively new regional anesthetic technique. Apart from case reports and small series, the literature regarding pediatric use is limited.
Aim:
Our objective was to determine the efficacy of the erector spinae plane block in children by measuring the heart rate response to incision. Secondary objectives included feasibility, safety, opioid consumption, and pain scores. Furthermore, we reviewed this block in children published since 2016.
Study Design:
Case Series; Level of evidence, IV.
Methods:
With Institutional Review Board approval, a retrospective chart review was conducted on all patients who received erector spinae plane block for surgery between October 2017 and May 2019 at a single institution. Blocks were performed under anesthesia, using ultrasound guidance prior to surgical incision. Block details and hemodynamic and analgesic data were collected. In addition, a PubMed literature review was conducted to identify all erector spinae plane block related publications in patients ≤18 years of age.
Results:
About 164 patients, 2 days-19.4 years, weighing 2.3-94.7 kg, received erector spinae plane blocks. For more than 79% of single injection blocks, placement time was ≤10 minutes. Using a heart rate increase of <10% at skin incision as criterion, 70.1% of patients had a successful block. Only 20% required long-acting opioids intraoperatively. In a subset of infants who underwent gastrostomy surgery using a dose of 0.5 mL/kg, a local anesthetic spread of at least five dermatomes (0.1 mL/kg/dermatome) was achieved. Per the literature review, 33 publications described erector spinae plane block in 128 children. No complications were reported.
Conclusion:
Erector spinae plane blocks are relatively easy to perform in children with no complications reported to date. The efficacy of the block for a broad spectrum of surgeries, involving incisions from T1 to L4, is encouraging.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
01:22Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
