A 27-year-old female with Trisomy 9 mosaicism presented to Children's Hospital Colorado for outpatient dental surgery under general anesthesia. The patient's past medical history was also significant for premature birth, gastroesophageal reflux, scoliosis and kyphosis, obesity, and developmental delay. Per her mother's report, the patient had no cardiac issues. She had undergone multiple previous general anesthetics, some of which documented respiratory complications such as laryngospasm, bronchospasm, and possible aspiration...

Study Design Randomized controlled trial. Objective Adolescent idiopathic scoliosis (AIS) is a common spinal deformity that affects every population. In severe deformity, surgical intervention is performed. Autogenous iliac crest bone graft (ICBG) harvesting remains a common procedure worldwide for scoliosis surgery. Postoperative pain at the ICBG donor site is a major concern in patients undergoing spine surgery that affects postoperative functional outcome and consumes health care resources. Previous studies have noted a decrease in pain and postoperative analgesic use with the application of continuous infusion of anesthetic at the ICBG site in comparison with placebo...

BACKGROUND: VEPTR (vertical expandable prosthetic titanium rib) expansion thoracoplasty is used to manage thoracic insufficiency syndrome in early-onset scoliosis. Literature regarding the effects of this technique on pulmonary function is scarce. The aim of this study was to report the intermediate-term results of VEPTR expansion thoracoplasty. METHODS: Twenty-one children with thoracic insufficiency syndrome underwent VEPTR expansion thoracoplasty from 2002 to 2012 and had complete chart data, preoperative and follow-up radiographs, and pulmonary function tests performed at the index implantation, first expansion, and last expansion...

STUDY DESIGN: Case series. OBJECTIVE: To determine whether there is improvement in pulmonary function in children with early-onset scoliosis (EOS) using magnetic growth rods (MGRs). SUMMARY OF BACKGROUND DATA: EOS deformities have large impacts on lung function and volumes. Deterioration of pulmonary function in scoliosis is multifactorial, including severity, location of apex vertebra, and medical comorbidities. MGR insertion has benefits including reduction in operative procedures with repeated anesthetics, cost-effectiveness, and minimizing surgical and psychological distress...

Spinal fusion surgery is a major surgery that results in severe postoperative pain, therefore pain reduction is a primary concern. New strategies for pain management are currently under investigation and include multimodal treatment. A 3-year retrospective analysis of patients with idiopathic scoliosis undergoing spinal fusion surgery was performed at our hospital, assessing patient pain scores, opioid use, and recovery. We evaluated the effect of adding continuous infusion of local anesthetics (CILA) to a postoperative pain management protocol that includes intraoperative intrathecal morphine, as well as postoperative patient-controlled analgesia and oral opioid/acetaminophen combination...

STUDY DESIGN: Case report. OBJECTIVE: To report a case of a true-positive isolated somatosensory evoked potential (SSEP) loss with preservation of motor evoked potential (MEP) response during scoliosis correction. SUMMARY OF BACKGROUND DATA: Combined intraoperative monitoring uses SSEPs and MEPs to decrease the probability of observing false-negative events. In combination, SSEPs and MEPs have become a standard of care for spinal deformity surgery...

BACKGROUND: Methadone is frequently administered to adults experiencing anesthesia and receiving pain treatment. Methadone pharmacokinetics in adults are well characterized, including the perioperative period. Methadone is also used in children. There is, however, no information on methadone pharmacokinetics in children of any age. The purpose of this investigation was to determine the pharmacokinetics of intravenous methadone in children undergoing surgery. Perioperative opioid-sparing effects were also assessed...

BACKGROUND: Poor surface anatomic landmarks are highly predictive of technical difficulty in neuraxial blockade. The authors examined the use of ultrasound imaging to reduce this difficulty. METHODS: The authors recruited 120 orthopedic patients with one of the following: body mass index more than 35 kg/m² and poorly palpable spinous processes; moderate to severe lumbar scoliosis; or previous lumbar spine surgery. Patients were randomized to receive spinal anesthetic by the conventional surface landmark-guided technique (group LM) or by an ultrasound-guided technique (group US)...

A 12-year-old girl with severe scoliosis underwent an operative procedure for correction of her spine deformity. Spinal cord injury is one of the most feared complications of scoliosis surgery. Therefore, it is necessary to detect spinal injury as early as possible. Intraoperative wake-up test is used to monitor spinal cord function during surgery. We used an intraoperative wake-up test with the concept of target-controlled infusion and total intravenous anesthesia (propofol and remifentanil). The use of Bispectral Index monitoring as a measure of depth of anesthesia enabled the patient to awake rapidly and consequently we did an immediate evaluation of muscle strength of lower extremities...

STUDY DESIGN: Retrospective chart review. OBJECTIVE: To determine the effectiveness of epidural analgesia in scoliosis patients with an opened (violated) spinal canal. BACKGROUND: Postoperative continuous epidural analgesia using local anesthetics and/or opioids has been described with good success after posterior scoliosis correction. One of the concerns with the use of epidural catheters for pain control is the reliability and distribution of analgesic medication when the epidural space is violated intraoperatively by Smith-Petersen osteotomies or placement of multiple sublaminar wires...

Anterior spine fusion by thoracotomy is indicated for the treatment of idiopathic scoliosis. Although epidural (EP) analgesia represents the most effective way to provide adequate analgesia after thoracotomy, scoliosis patients have substantial anatomic variations that make EP catheter placement more difficult and often contraindicated. This case report describes a safe, effective technique for placing a thoracic EP catheter in a young patient undergoing anterior spine fusion surgery by thoracotomy. The procedure was guided by both ultrasound (US) and electrical stimulation of the Tuohy needle and catheter...

The effect on pulmonary function of serial VEPTR expansion thoracoplasty was studied longitudinally in anesthetized children with spondylothoracic dysplasia using a special mobile unit. The median age of 24 children at the start of surgery was 4.6 years (1.8-10.8) and most exhibited a moderate-to-severe restrictive lung defect. After a median of 3.2 years (1.0-6.5), their forced vital capacity (FVC) was found to have increased by an average of 11.1%/year. The rate of increase was greater in children who were younger than 6 years at the start of the study than in older children (14...

In this chapter, we review current techniques employed to decrease blood loss and describe the effective use of a unique bipolar electrocautery device in a patient with neuromuscular scoliosis undergoing posterior spinal fusion (PSF). The reduction of blood loss and subsequent elimination of allogeneic blood transfusion is a desired outcome in all surgeries and is a major concern during PSF. In the child or adolescent with neuromuscular scoliosis, this becomes a greater concern due to a variety of factors such as the inability of the musculature to compress blood vessels, extensive surgical exposure, and the duration of the operation...
