title: Effectiveness of Arndt endobronchial blockers in pediatric scoliosis surgery: a case series.
abstract: BACKGROUND
  Pediatric scoliosis surgery may require single lung ventilation for surgical access. Current methods of lung isolation are inadequate for some or all of these children. The Arndt endobronchial blocker (EBB) has been described for use in pediatric thoracic surgery to enable single lung ventilation (SLV). There are few data on its use in pediatric spinal deformity surgery. We report the successful use of the Arndt EBB in a series of these patients.
  
  
  METHODS
  Any patient undergoing surgical correction of scoliosis involving a lateral thoracotomy for an anterior approach was managed with an Arndt EBB (5, 7 and 9 Fr gauge) to facilitate SLV. All cases were undertaken by a pediatric anesthetist trained in pediatric bronchoscopy; a 2.2 or 2.8 mm pediatric fiberoptic scope was used for placement and positional confirmation.
  
  
  RESULTS
  Patients' ages and weights ranged from 18 months to 18 years, and from 9.4 to 71 kg. All had idiopathic or congenital scoliosis; one underwent a vertical expansion prosthetic titanium rib (VEPTR) procedure. In all 20 patients, placement was easily and quickly achieved with no incorrect placements. There was one displacement after inflation, quickly corrected. Right upper lobe deflation proved difficult in one patient with high take-off of the right upper lobe bronchus. The surgical field was excellent in all cases.
  
  
  CONCLUSIONS
  In our case series, Arndt EBB provided a safe and highly effective means of single lung isolation for children undergoing pediatric scoliosis surgery.
