Clinical observation of diaphragm plication after pediatric congenital heart disease surgery / 中国小儿急救医学

Objective:To analyze the risk factors of performing diaphragm plication(DPL) after congenital heart disease(CHD) surgery as well as the timing and clinical efficacy.Methods:Data regarding children underwent open heart surgery at Shanghai Children′s Medical Center from January 2017 to December 2019 were reviewed.According to whether DPL was performed after CHD operation or not, the children were divided into DPL group and non-diaphragm plication(NDPL)group.Clinical data including age, surgery, cardiopulmonary bypass(CPB)temperature and time of two groups were compared, meanwhile the risk factors of DPL surgery were analyzed.Based on the median of 8 days between open heart surgery and DPL, children in DPL group were divided into early surgery group(less than 8 days), and delayed operation group(no less than 8 days). The parameters of comparison included ventilator using time, hospital stay time, hospitalization expenditure, postoperative infection to evaluate the timing of DPL and effect.Results:There were 10 309 children after CHD, including 95 in DPL group and 10 214 in NDPL group.In DPL group, there were 52 males(54.7%) and 43 females(45.3%), with age 147(52, 318) d, weight(5.5±4.1) kg, height(56.8±25.6) cm, CPB time(136.8±93.4) min and aortic occlusion time(62.5±50.2) min.Compared with NDPL group, DPL group had younger age, shorter height, lighter weight, higher incidence of preoperative special treatment, higher proportion of reoperation, lower CPB temperature, longer CPB time and longer aortic occlusion time.There were significant differences between two groups( P<0.05). Multivariate Logistic regression analysis showed that younger operative age( OR=0.998, 95% CI 0.998~0.999, P<0.001), staging operation( OR=72.977, 95% CI 39.096~136.211, P<0.001), long CPB time( OR=1.006, 95% CI 1.002~1.011, P=0.008), and pulmonary venoplasty( OR=4.219, 95% CI 2.132~8.350, P<0.001) were independent risk factors for DPL after CHD.Early surgery group had lower postoperative infection rate(43.59% vs. 88.38%, P=0.007), shorter ventilator duration[168.0(99.5, 280.5) h vs.309.9(166.2, 644.5) h, P=0.029], shorter hospital stay duration[27.00(20.75, 35.00)d vs.37.00(28.00, 53.00)d, P<0.001], and lower hospitalization cost[158.36(128.99, 203.11) thousand yuan vs.232.95(174.54, 316.47) thousand yuan, P<0.001] than delayed operation group. Conclusion:Younger age, staging operation, long CPB time, and pulmonary venoplasty are independent risk factors for DPL due to diaphragmatic paralysis after pediatric CHD surgery.Early surgical intervention is beneficial for the recovery of children.

Clinical efficacy of diaphragmatic plication in the treatment of diaphragmatic paralysis after congenital heart defect operation / 中国胸心血管外科临床杂志

@#Objective    To investigate the timing and clinical efficacy of diaphragmatic plication in the treatment of diaphragmatic paralysis after congenital heart disease (CHD) operation. Methods    From January 2013 to February 2019, 30 children with CHD who were treated in Fuwai Hospital were collected, including 17 males and 13 females with a median age of 19.5 (3, 72) months. There were 6 patients with bilateral diaphragmatic paralysis (bilateral group) and 24 patients with unilateral diaphragmatic paralysis (unilateral group). The clinical data of the two groups were compared. Results    Among the 6 bilateral diaphragmatic paralysis patients, 2 underwent bilateral diaphragmatic plication, and the other 4 patients continued their off-line exercise after unilateral diaphragmatic plication. Patients in the unilateral group had shorter ventilator use time (266.77±338.34 h vs. 995.33±622.29 h, P=0.001) and total ICU stay time (33.21±23.97 d vs. 67.33±28.54 d, P=0.008) than those in the bilateral group. One patient died in the bilateral group, and there was no statistical difference between the two groups (P=0.363). There was no statistical difference in the ICU stay time after diaphragm plication between the two groups (11.68±10.28 d vs. 29.83±27.73 d, P>0.05). Conclusion    Diaphragmatic plication is an effective treatment for diaphragmatic paralysis after CHD operation once the conservative treatment failed. The prognosis of bilateral diaphragmatic paralysis is worse than that of unilateral diaphragmatic paralysis. Strict control of indications for surgery is beneficial to the early recovery of patients.

Is polysomnographic examination necessary for subjects with diaphragm pathologies?

OBJECTIVES: While respiratory distress is accepted as the only indication for diaphragmatic plication surgery, sleep disorders have been underestimated. In this study, we aimed to detect the sleep disorders that accompany diaphragm pathologies. Specifically, the association of obstructive sleep apnea syndrome with diaphragm eventration and diaphragm paralysis was evaluated. METHODS: This study was performed in Süreyyapasa Chest Diseases and Thoracic Surgery Training and Research Hospital between 2014-2016. All patients had symptoms of obstructive sleep apnea (snoring and/or cessation of breath during sleep and/or daytime sleepiness) and underwent diaphragmatic plication via video-assisted mini-thoracotomy. Additionally, all patients underwent pre- and postoperative full-night polysomnography. Pre- and postoperative clinical findings, polysomnography results, Epworth sleepiness scale scores and pulmonary function test results were compared. RESULTS: Twelve patients (7 males) with a mean age of 48 (range, 27-60) years and a mean body mass index of 25 (range, 20-30) kg/m2 were included in the study. Preoperative polysomnography showed obstructive sleep apnea syndrome in 9 of the 12 patients (75%), while 3 of the patients (25%) were regarded as normal. Postoperatively, patient complaints, apnea hypopnea indices, Epworth sleepiness scale scores and pulmonary function test results all demonstrated remarkable improvement. CONCLUSION: All patients suffering from diaphragm pathologies with symptoms should undergo polysomnography, and patients diagnosed with obstructive sleep apnea syndrome should be operated on. In this way, long-term comorbidities of sleep disorders may be prevented.

Eventración diafragmática en el recién nacido / Diaphragmatic Hernia in the Newborn

La eventración diafragmática es una anomalía relativamente rara, se presenta con una elevación anormal de todo o una parte del hemidiafragma intacto. Se presentó un recién nacido de 41 semanas de edad gestacional, sin diagnóstico prenatal de malformación congénita, parto por cesárea por sufrimiento fetal agudo que se realizó en el Hospital Provincial Docente Carlos Manuel de Céspedes de Bayamo, Granma, nació deprimido, y en su evolución requirió intubación endotraqueal y ventilación mecánica. Se realizó radiografía de tórax, se interpretó como una hernia diafragmática derecha, se adoptaron las medidas correspondientes para su estabilización y se trasladó al Centro Regional de Cirugía Neonatal en Holguín. Se realizó ultrasonido toracoabdominal, y toracotomía derecha, se encontró una eventración diafragmática. Se realizó plicatura del músculo diafragma. A las 48 h presentó trastornos en la perfusión y la radiografía de tórax mostró imagen de neumoperitoneo, se reintervino y se encontró perforación puntiforme en el yeyuno que se suturó. La evolución postoperatoria fue satisfactoria.

A diaphragmatic hernia is a relatively rare condition with an abnormal elevation of the intact diaphragm. A newborn, of 41 weeks of gestation, without prenatal diagnosis of congenital malformation was presented; cesarean delivery was done in “Carlos M. de Céspedes” provincial hospital. Endotraqueal intubation and mechanical ventilation were required. Chest radiography showed diaphragmatic hernia, the patient was stabilized and referred to the Regional Neonatal Surgery Center. Sonographic scan was done and right thoracotomy, diaphragmatic hernia was found. The patient was operated on again in the next 48 hours; a yeyunal perforation was done and closed. The post operatory evolution was satisfactory.

Clinical diagnosis and surgical treatment of diaphragmatic paralysis in infants with congenital heart disease after cardiac surgery / 中华实用儿科临床杂志

Objective To investigate the clinical manifestations,diagnosis and treatment of diagrammatic paralysis in infants with congenital heart disease (CHD) after cardiac surgery.Methods Thirty-one cases of diaphragmatic paralysis after cardiac surgery were selected from Jan.2006 to Jun.2012,including 23 cases were male and 8 cases were female.The age at operation was 20 days to 25 months,(8.0 ± 5.5) months on the average.The body weight at operation was 3.1-12.2 kg,(6.8 ± 2.3) kg on the average.All children received machine auxiliary breathing,and they had breathing difficulty without the machine.Diaphragmatic plication via 6-8 intercostal was performed under general anesthesia and endotracheal intubation.Lateral position,with uninjured side downward,was taken to perform chest posterolateral incision or chest lateral incision.Relaxing and weak diaphragm muscles were resected or directly sutured after folding.The clinical manifestations and diagnosis of children were summarized,and the effectiveness of diaphragmatic plication was evaluated.Results In 31 cases with diaphragmatic paralysis,there were 15 cases with left diaphragmatic paralysis,12 cases with right diaphragmatic paralysis,and 4 cases with bilateral diaphragmatic paralysis.Thirty-one cases had dyspnea after weaning of ventilator,and 28 cases received reintubation,23 cases with ventilator-as-sociated pneumonia,and 10 cases with tracheotomy.Diaphragmatic plication was performed in 28 cases,and all of them were weaned off ventilator successfully after the placation.The time of preoperative mechanical ventilation lasted 119-827 hours [(447 ± 225) hours],postoperative ventilator assistance time was 12-206 hours [(71 ± 52) hours],which showed significant difference in time of ventilation(P ＜0.05).Conservative treatment was given to the remaining 3 cases,and they were weaned off ventilation successfully with a better recovery.Conclusions Diaphragmatic paralysis in infants after CHD surgery affects their recovery.Diaphragm plication is a safe and effective method to treat the diaphragm paralysis.

Successful Weaning after Diaphragmatic Plication in an Infant with Phrenic Nerve Palsy Resulting from Removal of Cavernous Lymphangioma / 대한구급학회지

Phrenic nerve palsy is a well-known complication following cardiac surgery in children. The incidence is approximately 1~2%. In infants and young children, it often causes a life-threatening respiratory distress. They must be treated with mechanical ventilation in the ICU. Many patients with phrenic nerve injury who is impossible to wean from a ventilator are candidates of diaphragmatic plication. Diaphragmatic plication is performed to restore the normal pulmonary parenchymal volume by replacing the diaphragm to its proper location. This is a case of 2-months-old infant who had phrenic nerve palsy after the removal of cavernous lymphangioma of the chest. He underwent 4 operations to remove the mass and to have pericardiotomy. We tried to wean him from the ventilator but failed several times in the ICU. After 4th operation, right diaphragmatic elevation was noted from the chest X ray. Phrenic nerve palsy was confirmed with fluoroscopy and he underwent diaphragmatic plication on 42 days after his 4th operation. Three days after the diaphragmatic plication, weaning was successfully carried out.
