Abstract
This is a retrospective study. To assess the effects of noninvasive positive-pressure ventilation (NIPPV) through evaluations of outcomes and incidences of postoperative pulmonary complications among patients with flaccid neuromuscular scoliosis for pulmonary support in the perioperative periods. There is no report on the effects of NIPPV on neuromuscular scoliosis patient during the perioperative periods. We retrospectively reviewed 73 patients diagnosed with neuromuscular scoliosis who underwent staged anterior and posterior spinal surgery and instrumentations for deformity correction from 2003 to 2010. A total of 73 patients were divided depending on whether they had received NIPPV treatment or not during the perioperative period. Twenty-eight patients who received NIPPV for respiratory support and 45 patients with no mechanical ventilation were compared according to age, sex, body mass index, number of fusion levels, and end-tidal pressure of CO(2) and forced vital capacity values. The incidence of pulmonary complications associated with either group (pneumonia, atelectasis, pneumothorax, prolonged ventilator support, and postoperative tracheostomy) was then evaluated. In between the 2 groups, the forced vital capacity (41% vs. 64%, P<0.0001) were observed to be significantly decreased with the use of NIPPV. End-tidal pressure of CO(2) was not statistically different between the 2 groups. Although statistically not significant, patients in the non-NIPPV group had a higher incidence of pulmonary complications (38% vs. 21%, P=0.1584). None of the aforementioned patients required tracheostomy. In addition, no other mortality or neurological complications were noted postoperatively. There is a definite advantage of using NIPPV, because the incidence of postoperative pulmonary complications and the need for tracheostomy in patients with severely decreased pulmonary function are not increased from the use of NIPPV.
