ObjectiveTo summarize the experience of surgical treatment of asphyxiating thoracic dysplasia (Jeune syndrome).MethodsA total of 15 patients with asphyxiating thoracic dysplasia from August 2018 to April 2020 in our hospital were retrospectively included. There were 7 males and 8 females, aged 1-25 (8.87±6.71) years. Special steel bars were used to correct the growth direction of the rib and costal cartilage. Meanwhile, the concave and convex deformities of the chest wall on both sides were corrected to increase the chest volume and correct the thoracic deformity.ResultsThe contour appearance of the chest wall of all patients changed after the operation. The shape was close to normal, and the symptoms of hypoxia were improved. The operation time was 147.73±59.78 min, intraoperative bleeding volume was 105.67±91.90 mL, ICU stay time was 14.20±13.54 d and hospital stay time was 26.00±17.87 d. Eleven patients were directly extubated after the operation, 4 patients underwent tracheotomy and received assisted respiration, and the assisted respiration time was 19, 13, 22 and 12 days, respectively. The postoperative chest circumference was significantly increased, and the blood oxygen saturation was significantly improved. There were 5 patients with cardiac insufficiency, and 3 of them were improved by cardiotonic therapy, 2 of them died of heart failure on the 2nd and 31st day after the operation, respectively. Abdominal distention occurred in 10 patients after operation, and 5 of them were obstinate and eliminated by comprehensive treatment. All patients were followed up. The appearance of thorax was improved obviously and there was no sign of compression in lungs. One 13-year-old patient developed respiratory discomfort 3 months after the operation, and the symptoms were relieved after self-administration of oxygen. A 25-year-old patient developed cardiac insufficiency half a month after the discharge, and the symptoms disappeared after cardiotonic treatment. Four patients took out the steel bars in 13, 13, 15 and 17 months after the operation, respectively. The appearance of thorax remained well after the operation. The imaging examination showed that the position of bone structure was normal, the lung field was clear, and there was no sign of chronic inflammation.ConclusionThis technique is a safe and simple operation method. It can not only eliminate the deformity of chest wall, but also increase the volume of chest obviously. However, the long-term effect needs to be further evaluated.
Objective To investigate the related factors of the retinal hemorrhage in high-risk infants (HRI). Methods Eight hundred and sixty HRI with histories of high-risk pregnancy and/or neonatal asphyxia after 1-5 days of birth were enrolled in this study.In 860 cases of HRI, 498 infants were vaginal delivery and 362 infants were delivered through cesarean sections. Among 498 vaginal delivered infants, 407 infants were eutocia and 91 infants were with forceps delivery; 298 infants were born following normal labor, 102 infants experienced prolonged labor, and 98 infants were urgent birth. The retinal hemorrhages were observed and conditions were graded into three degrees of Ⅰ, Ⅱ, and Ⅲ. Conditions of neonatal asphyxia were evaluated based on criteria of Apgar score. The incidence of retinal hemorrhage in the different types of deliveries and labor processes were compared, and the relationship between degree of retinal hemorrhage and grade of neonatal asphyxia were analyzed. Results In 860 cases of HRI, retinal hemorrhages were found in 202 infants (23.5%). Within these 202 infants, 75 infants (37.1%) were Ⅰ degree retinal hemorrhage, 75 infants (37.1%) were Ⅱ degree retinal hemorrhage, and 52 infants (25.8%) were Ⅲ degree retinal hemorrhage. In these 202 infants of retinal hemorrhage, 172 infants (85.1%) had histories of asphyxia; 119 infants (69.2%) were graded as mild asphyxia-risk, and 53 infants (30.8%) were graded as severe asphyxiarisk. There was a statistical difference of the degree of the retinal hemorrhage between the mild and severe asphyxia-risk infants (chi;2=34.61,P＜0.01). The incidence of retinal hemorrhage after vaginal delivery was higher than cesarean section delivery with significant statistical difference (chi;2=30.73,P＜0.01). The incidence of retinal hemorrhage after forceps delivery was significantly higher than eutocia with statistical difference (chi;2=62.78,P＜0.01). Both prolonged and urgent childbirth had statistically significant higher incidences of retinal hemorrhage compared to normal labor in the process of vaginal delivery (chi;2=45.86, 71.51; P＜0.01). Asphyxia, types of delivery, prolonged and urgent labors were risk factors of retinal hemorrhage for HRI (r=7.46,4.87,15.03,6.47;P＜0.01). Conclusions The incidence of retinal hemorrhage in high-risk infant was 23.5%. And, asphyxia, types of delivery, prolonged and urgent labors may play roles of risk factor in retinal hemorrhage of HRI.
目的 評價不同復蘇方法和不同藥物、氧療、物理療法等對新生兒窒息復蘇和復蘇后的預防措施的有效性和安全性.方法 計算機檢索Cochrane Library(2004年第3期),MEDLINE(1966～2002年) 關于新生兒窒息復蘇時不同復蘇方法、氧氣的應用、以及不同藥物、劑量、給藥途徑治療和預防新生兒窒息的系統評價、隨機和半隨機對照試驗.結果 正壓通氣時使用100%氧氣和應用室內空氣的復蘇效果并無差異.胎糞污染羊水(MSAF)與較高的新生兒缺血缺氧性腦病(HIE)的發生率有關,而氣管內有胎糞者無論稀稠均與胎糞吸入綜合征發生率無關.窒息復蘇后預防性給予亞低溫療法、抗驚厥藥、納洛酮、多巴胺等在降低新生兒病死率,繼發HIE的嚴重程度等方面與對照組相比無顯著差異.應用肺表面活性物質(PS)預防和治療新生兒呼吸窘迫綜合征(RDS),可減少死亡率和并發癥.結論 應用PS預防和治療RDS可明顯減少新生兒死亡率,且胎齡lt;32周的早產兒預防用藥比治療用藥效果更好;目前尚無充分證據證明窒息復蘇后預防性給予亞低溫療法、抗驚厥藥、納洛酮、多巴胺等治療的有效性.
