Clinical Investigations: AirwaysEvidence of Airway Obstruction in Children With Idiopathic Scoliosis
Section snippets
Clinical Data
We performed pulmonary function tests on 59 children scheduled to have surgical correction of idiopathic scoliosis between January 1988 and December 1994. Forty-four subjects (36 females, 8 males) who had a thoracic curve greater than 35 degrees as measured by the method of Cobb6 and who did not have secondary scoliosis due to neuromuscular disease, metabolic disease, or trauma were included in the study.
All pulmonary function tests were done in a pediatric pulmonary function lab by the same
RESULTS
The mean age of the subjects was 13.6±0.33 years (range, 10 to 18 years) and the mean thoracic angle was 47±1.62 degrees (range, 35 to 90 degrees).
Based on ATS14 criteria, 26 (59%) subjects had no restrictive defects, 4 (9%) subjects had mild defects, 7 (16%) subjects had moderate defects, and 7 (16%) subjects had moderately severe defects (Fig 1).
The mean percent predicted FEV1 was 67%±2.5, with an FVC of 68%±2.6. The difference between the predicted and measured FEV1/FVC did not meet ITS13
DISCUSSION
It is generally accepted that alveolar hypoventilation and respiratory dysfunction leading to pulmonary hypertension and cor pulmonale is encountered with scoliosis patients whose curvature is greater than 90 degrees. However, pulmonary function defects may be seen with lesser degrees of scoliosis.15 The mean angle of our subjects was 47 degrees, a moderate, class 2 deformity based on the classification by Gozioglu et al.1 Even though 45% of our subjects had restrictive defects, none had a

Pulmonary function in children and adolescents with untreated idiopathic scoliosis: a systematic review with meta-regression analysis
2022, Spine JournalCitation Excerpt :A total of 126 articles were included in this systematic review, including 53 prospective, 67 retrospective, and six randomized studies. Supplementary table 1 provides a detailed summary of all included studies [2,5-11,16-133]. A total of 8,723 IS patients were reported in the 126 included studies describing a total of 204 patient groups.
The association between spinal column deformity and breathing function: A systematic review
2020, Journal of Bodywork and Movement TherapiesCitation Excerpt :To assess the angle of scoliosis the cobb angle was used. In seven articles the cobb angle was measured (Johari et al., 2016; Redding et al., 2008; McMaster et al., 2007; Newton et al., 2005; Smyth et al., 1984; Szinberg et al., 1988; Caro and DuBois, 1961), breathing muscles strength test was used in one study (Sperandio et al., 2015), diaphragm and chest wall movement test was investigated in one article (Kotani et al., 2004), only one study measured the Maximal Voluntary Ventilation (MVV) (Smyth et al., 1984),arterial oxygen partial pressure (Pao2) and arterial carbon dioxide partial pressure (Pa co2) were evaluated in one article (Pehrsson et al., 1991), Maximal inspiratory pressure (MIP) and Maximal Expiratory Pressure (MEP) were investigated in three studies (Martinez-Llorens et al., 2010; Smyth et al., 1984; Szinberg et al., 1988), specific airway conductance (sGaw), plethysmography (pleth) and Forced Expiratory Flow (FEF) were used for evaluation in only one study (Boyer et al., 1996), Blood Pressure (BP), Heart Rate (HR) and Respiratory rate (RR) were investigated in one article (Alves and Avanzi, 2009), also, two studies used the oximetry oxygen saturation (SPO2) in the evaluation process (Alves and Avanzi, 2009; Martinez-Llorens et al., 2010), diffusing capacity of the lung for carbon monoxide was used in one article (Martinez-Llorens et al., 2010), two articles investigated the Residual Volume (RV) (Leong et al., 1999; Pehrrson et al., 1991), Residual volume to total Lung Capacity ratio (RV/TLC) was assessed in two studies (Martinez-Llorens et al., 2010; Boyer et al., 1996) and only one article used the Functional Residual Capacity (FRC) (Pehrrson et al., 1991). This study was carried out to review the published studies and investigated the correlation between spinal column deformities and breathing function.
Does Scoliosis Affect Sleep Breathing?
2018, World NeurosurgeryCitation Excerpt :Previous studies have shown that scoliosis impairs respiratory function by limiting chest wall movement and preventing normal inflation of the lungs.8,9 Airway obstruction has also been observed in patients with scoliosis,10 which is thought to be the result of locational shift of intrathoracic organs.11 The nature of scoliosis may increase the risk of SDB in patients.
Long-term impact of pre-operative physical rehabilitation protocol on the 6-min walk test of patients with adolescent idiopathic scoliosis: A randomized clinical trial
2015, Revista Portuguesa de PneumologiaCitation Excerpt :When checking at which moments the groups are different, we observe that, for all variables described above, on average, the study group has lower values than the control group from the preoperative period on, except for the distance walked, which increases (p < 0.001). Patients with adolescent idiopathic scoliosis (AIS) frequently evolve with reduced vital capacity, and a drop in total pulmonary capacity associated to deficient arterial oxygenation and alveolar hypoventilation as a consequence of the tridimensional physical deformities of the spine.1,2,4,13 This was also observed in the present study, in which the patients with AIS had much lower baseline evaluations than would be expected for their age.
