Relationship between very low birth weight and very early premature delivery with neonatal survival status / 重庆医学

Objective To investigate the survival status and related influencing factors of very low birth weight infants(VL-BWI) and very early preterm infants(VPI).Methods One hundred and forty-two very low birth weight and very preterm infants in our hospital from April 2012 to January 2016 and contemporaneous 140 non-low-birth-weight and non-very-preterm infants were selected.The survival status of newborns and long-term prognosis were compared.The low birth weight children and very preterm infants were divided into the death group and survival group according to the survival status and long-term prognosis.The clinical data in the two groups were performed the univariate and multivariate Logistic regression analysis.Results The incidence rate of poor prognosis had statistically significant difference among neonates with birth weight less than 1 500,1 500-2 500 and＞2 500 g(P＜0.05).The incidence rate of poor prognosis had statistically significant difference among neonates with the gestational age≤32 weeks,32-37 weeks and≥37 weeks(P＜0.05).The proportions of gestational age,birth weight and antenatal dexamethasone use in the death group were significantly lower than those in the survival group,while the proportions of maternal age,asphyxia,meconium aspiration,pregnancy induced hypertension and mechanical ventilation in the death group were significantly higher than those in the survival group,the difference between two groups was statistically significant(P＜0.05).The gestational age≤28 weeks,birth weight≤1 000 g and asphyxia were the independent risk factors affecting the survival status in very low birth weight infants and extremely preterm infants(P＜0.05).Conclusion In VLBWI and VPI the living status,and long-term prognosis are poor and prone to mental and movement disorders.

Application of coblation in the treatment of nose and throat diseases / 中国耳鼻咽喉头颈外科

OBJECTIVE To investigate the efficacy of coblation in upper airway obstruction patients. METHODS Coblation Channeling was used in 814 obstructed nasal airway patients.Soft palate coblation with or without tonsil treatment was applied in 67 adult OSAHS patients.Coblation tonsillectomy or tonsillotomy with adenoidectomy was performed in 68 pediatric OSAHS patients.RESULTS For obstructed nasal airway patients,VAS scores of 720 (88.45 %) patients were 0 to 1 after one time treatment.Thirty-five (4.3 %) patients had second treatment,and then VAS scores dropped to 0 to 1.VAS scores of 59 (7.25 %) patients kept more than 5.For adult OSAHS patients,3 (4.5 %) patients were cured,38 (56.7 %) patients were improved, 19 (28 %) patients were effective and 7 patients were not improved.For pediatric OSAHS patient s,58 (85.29 %) patients' symptoms,such as snoring,breath difficulty, mouth breathing,or pharyngeal obstruction,were relieved and 10 (14.71%) patients' symptoms were improved. CONCLUSION Coblation is widely used in ENT patients with good results.Its advantages include easy to use, minimal invasive,safe,and much less pain.It is specially suitable for pediatric OSAHS patients.
