Accelerate postoperative management after scoliosis surgery in healthy and impaired children: intravenous opioid therapy versus epidural therapy

Bilateral Bi-Level Erector Spinae Plane Blocks as a Part of Opioid-Sparing Multimodal Analgesia in Scoliosis Surgery: A Case Series of Six Pediatric Patients

Background and Aim: Postoperative pain after scoliosis surgery is severe and usually requires long-term intravenous opioid therapy. Local anesthetic options, such as wound infiltration, are limited and include neuraxial analgesia. However, they are rarely used due to side effects and inconsistent efficacy. We report an opioid-sparing multimodal analgesia regimen with bilateral erector spinae plane blocks. This case series evaluated the analgesic effect of the bilateral bi-level erector spinae plane blocks (ESP) in congenital and neurogenic scoliosis surgery. Patients and Methods: Six pediatric patients with congenital or neurogenic scoliosis underwent posterior spinal fusion involving 5 to 12 vertebral levels. Bilateral single-injection ESPB was performed at one or two levels before incision. Preoperatively, patients received intravenous dexamethasone. General anesthesia with endotracheal intubation and volume-controlled ventilation was performed via TIVA with remifentanil and propofol. During and after the procedure, the basic hemodynamic parameters, opioid consumption, pain scores (numerical rating scale/NRS), and possible block complications were monitored. Results: All the patients experienced minimal postoperative pain levels. In addition, on the first day after surgery, they had low opioid requirements with no side effects. Conclusions: ESPB in patients undergoing congenital and neurogenic scoliosis correction surgery seems to be an essential analgesic technique that may reduce both severities of pain and opioid consumption.

Anesthesia and Perioperative Management for Surgical Correction of Neuromuscular Scoliosis in Children: A Narrative Review

Scoliosis is the most frequent spinal deformity in children. It is defined as a spine deviation of more than 10° in the frontal plane. Neuromuscular scoliosis is associated with a heterogeneous spectrum of muscular or neurological symptoms. Anesthesia and surgery for neuromuscular scoliosis have a higher risk of perioperative complications than for idiopathic scoliosis. However, patients and their relatives report improved quality of life after the surgery. The challenges for the anesthetic team result from the specifics of the anesthesia, the scoliosis surgery itself, or factors associated with neuromuscular disorders. This article includes details of preanesthetic evaluation, intraoperative management, and postoperative care in the intensive care unit from an anesthetic view. In summary, adequate care for patients who have neuromuscular scoliosis requires interdisciplinary cooperation. This comprehensive review covers information about the perioperative management of neuromuscular scoliosis for all healthcare providers who take care of these patients during the perioperative period, with an emphasis on anesthesia management.

Rapid recovery pathway without epidural catheter analgesia for surgical treatment of adolescent idiopathic scoliosis: a comparative study

PURPOSE

To assess effectiveness of a rapid recovery pathway (RRP) without epidural catheter analgesia (ECA) or intravenous patient controlled analgesia (PCA) in accelerating recovery and decreasing opioid consumption in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF).

METHODS

A retrospective cohort study included collection of demographics, ECA use, IV PCA, postoperative opioid consumption, postoperative pain scores, and reoperation rate. Opioid consumption was calculated using morphine milligram equivalents (MME). Hospital length of stay (HLOS) and first reported ambulation with physical therapy (PT) were also recorded.

RESULTS

53 patients were included, with 18 in the RRP group. Patient characteristics were comparable between the groups, except in ECA use and BMI. The RRP group consumed less total MME from postoperative day (POD) 0 to 2 (mean difference 61.6 MME; 95% CI 37.1-86.1 MME; p < 0.001). In addition, the RRP group had significantly shorter HLOS (2.5 vs 4.0 days; p < 0.001). There were no differences in VAS scores between the two groups. A subset analysis comparing patients who did and did not receive ECA showed that ECA resulted in overall higher inpatient MME and HLOS. A prediction model was developed using multiple regression based on the different medications used for multimodal analgesia (MMA) in the RRP.

CONCLUSIONS

An RRP without the use of ECA or IV PCA can provide adequate analgesia in patients with AIS undergoing PSF while lowering inpatient narcotic consumption and accelerating immediate postoperative recovery.

Clinical Update on Patient-Controlled Analgesia for Acute Postoperative Pain

Patient-controlled analgesia (PCA) is an effective method for controlling acute pain, including postoperative pain in adults and in children from five years of age, pain resulting from labor, trauma, or other medical situations, or chronic and malignant pain. The treatment consists of a mini-computer-controlled infusion pump permitting the administration of on-demand, continuous, or combined doses of analgesic (mainly opioid) variations in response to therapy, which allows pain to be significantly controlled. Intravenous (IV)-PCA minimizes individual pharmacodynamics and pharmacokinetic differences and is widely accepted as a reference method for mild or severe postoperative pain. IV-PCA is the most studied route of PCA; other delivery methods have been extensively reported in the literature. In addition, IV-PCA usually voids the gap between pain sensation and analgesic administration, permitting better recovery and fewer side effects. The most commonly observed complications are nausea and vomiting, pruritus, respiratory depression, sedation, confusion and urinary retention. However, human factors such as pharmacy preparation and device programming can also be involved in the occurrence of these complications, while device failure is much less of an issue.
