Sleep Breathing Recordings In Patients With Scoliosis

Scoliosis is the most common spinal deformity,often accompanied by abnormal respiratory system function.There are few studies on the relationship between scoliosis patients and changes in sleep respiration.This study intends to explore the relationship between the severity of scoliosis in patients with different causes and the results of sleep breathing recording.Part Ⅰ:Effects of idiopathic scoliosis on sleep breathingBackground:Idiopathic scoliosis(IS)is a three-dimensional deformity of the spine.The relationship between thoracic scoliosis and lung function impairment has been widely concerned.Sleep disordered breathing has been found in people with scoliosis,but the relationship between scoliosis and sleep disordered breathing remains to be studied.Polysomnograpgy(PSG)can monitor patients’ sleep respiration,so as to evaluate their sleep breathing function and diagnose sleep breathing disorder.Objective:To analyze the association between polysomnography monitoring results and the imaging parameters of thoracic deformity and lung function measurements in patients with idiopathic scoliosis.Methods:Clinical data of patients with idiopathic scoliosis admitted to our hospital from January 2020 to December 2021 were retrospectively collected.Radiographic measurements including scoliosis and thoracic malformation parameters were performed based on whole spine X-rays and Bending films,and pulmonary function measurements and sleep breathing recording results were collected for correlation analysis.Results:A total of 81 patients with idiopathic scoliosis,including 68 women and 13 men,16 patients(19.8%)met the diagnosis of obstructive sleep apnea.In this group of patients,with the gradual increase of the rotation degree of the apex of the main thoracic curvature and the length of the main thoracic curvature,FEV1 and FVC showed a significant decreasing trend,and there was a significant negative correlation between main thoracic curvature and Lowest oxygen saturation(Lowest SpO2)in sleep breathing recording results(r=-0.233,p=0.036).The degree of thoracic kyphosis was significantly positively correlated with FEV1/FVC and FEV1.FEV1 and FVC were significantly negatively correlated with oxygen desaturation index(ODI)(r=-0.242,p=0.03).In the thoracic diameter line,TD was significantly positively correlated with FVC,FEV1,FEV1/FVC.TW was significantly positively correlated with FVC and FEV1.Conclusion:In idiopathic scoliosis,decreased lung function was associated with severity of thoracic deformity.Severity of decreased oxygen saturation during sleep was associated with frequency of decreased oxygen saturation during sleep.In addition,the thoracic diameter line was significantly associated with impaired lung functionPart Ⅱ:Sleep breathing recording in patients with congenital scoliosisBackground:Congenital scoliosis is characterized by early onset and rapid progression of deformity,and is often accompanied by thoracic cage deformity.Therefore,congenital scoliosis often combined with respiratory system damage.Obstructive sleep breathing disorder is a common sleep breathing disorder,which may also exist in patients with congenital scoliosis.Pulmonary function measurement cannot detect abnormal sleep respiratory function,and sleep breathing recording is needed to assess the abnormal sleep respiratory function in patients with congenital scoliosis.Objective:To analyze the association between polysomnography monitoring results and the imaging parameters of thoracic cage deformity and lung function measurements in patients with congenital scoliosis.Methods:Clinical data of patients with congenital spinal malformation admitted to our hospital from January 2020 to December 2021 were retrospectively collected.Radiographic measurements including scoliosis and thoracic malformation parameters were performed based on whole spine X-rays and Bending films,and pulmonary function measurements and polysomnography monitoring results were collected for correlation analysis.Results:A total of 18 patients with congenital spinal deformity were included,including 11 females and 7 males,with an average age of 15.2±6.1 years.In pulmonary function testing,10 patients(55.6%)had no or mild lung function impairment,5 patients(27.8%)had moderate lung function impairment,and 3 patients(16.4%)had severe lung function impairment.Five of the 18 patients(27.7%)were diagnosed with obstructive sleep apnea.As the length of thoracic scoliosis increased,FEVi and FVC decreased significantly in lung function measurements,and TW and TD were significantly positively correlated with FVC.In this group of patients,no association was found between the severity of congenital scoliosis thoracic deformity and the results of polysomnography monitoring,nor between lung function and the results of polysomnography monitoring.Conclusion:In this group of patients with congenital scoliosis,27.7%were diagnosed with obstructive sleep apnea.Impaired pulmonary function was associated with the length of thoracic scoliosis.The thoracic diameter line was significantly associated with impaired pulmonary function.There was no association between the severity of congenital scoliosis and the results of sleep breathing recording in this group of patients.
