Erector spinae catheter for post-thoracotomy pain control in a premature neonate

Perioperative and Anesthetic Considerations in Vascular Rings and Slings

Vascular rings represent an increasingly prevalent and diverse set of congenital malformations in which the aortic arch and its primary branches encircle and constrict the esophagus and trachea. Perioperative management varies significantly based on the type of lesion, its associated comorbidities, and the compromise of adjacent structures. Multiple review articles have been published describing the scope of vascular rings and relevant concerns from a surgical perspective. This review seeks to discuss the perioperative implications and recommendations of such pathology from the perspective of an anesthesia provider.

Erector spinae plane block for surgery of esophageal atresia in a preterm neonate

Pain management during and after thoracotomy is challenging in premature neonates. Ultrasound-guided fascial plane block techniques, such as the erector spinae plane block are a relatively new regional anesthesia technique and have emerged as an alternative to thoracic epidural due to its clinical effectiveness, ease of administration and theoretically being safer to perform. The relative ease of identifying anatomical landmarks compared to the paravertebral block, as well as its safety profile compared to an epidural, may have contributed to the erector spinae plane Bs growing popularity. Currently, however, the published evidence for the efficacy of regional anesthesia techniques in low birth weight newborns undergoing this surgery is limited to few isolated case reports. Herein we describe the use of unilateral erector spinae plane block as part of anesthesia and postoperative analgesia management of surgical correction of esophageal atresia in a preterm neonate.

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.

Evolving approaches in neonatal postoperative pain management

Neonates experience significant moderate and severe postoperative pain. Effective postoperative pain management in neonates is required to minimize acute and long-term effects of neonatal pain. Protecting the developing nervous system from persistent sensitization of pain pathways and developing primary hyperalgesia is essential. Opioids and acetaminophen are commonly analgesics used for pain control. Regional anesthesia provides adequate intraoperative and postoperative analgesia in neonates. It decreases exposure to opioids, reduces adverse drug effects, and facilitates early extubation. It suppresses the stress response and can prevent long-term behavioral responses to pain. The most common blocks performed in neonates are neuraxial blocks. Using ultrasound increased the number of peripheral nerve blocks performed in neonates. Recently, various peripheral nerve blocks (paravertebral, transverse abdominis plane, rectus sheath, quadratus lumborum, erector spinae plane blocks) were safely used. Many studies support analgesic efficacy but highlight neonates' unpredictability and variability of fascial blocks.

Continuous Local Anesthetic Infusion via Chest Wall Catheter for Analgesia After Thoracic Surgery in Neonates: A Case Series

Pain management options in neonates after thoracotomy have traditionally been limited to intravenous opioids and caudal catheters. However, because of increasing familiarity with ultrasound imaging, erector spinae and paravertebral nerve blocks are being performed more frequently. For thoracic procedures, we describe a case series of 4 neonates involving ropivacaine infusion via an extrathoracic chest wall catheter placed by the surgeon. This technique requires less time, is less invasive, does not require ultrasound, and enabled us to accomplish tracheal extubation in the operating room immediately after surgery, and decreased postoperative opioid use in the neonatal intensive care unit.
