ABSTRACT
Objective:To evaluate the effect of oropharyngeal colostrum administration on building adequate enteral feeding process of very low birth weight neonates and extremely low birth weight neonates.Methods:A total of 62 very/extremely low birth weight neonates in NICU were selected from a tertiary hospital in shandong province. They were randomly assigned to the observation group ( n=32) and the control group ( n=30) according to the random number table. The observation group was given oropharyngeal colostrum administration. The control group was given oral care with 0.9% sodium chloride solution, and the wiping method and frequency was the same as the observation group. Gastric retention, enteral feeding time, adequate enteral feeding time, the weight at the time of discharge, etc. were compared between two groups. Results:Gastric retention times on the 10th day in the observation group (1.90±1.30) was significantly lower than that in the control group (2.77±1.50), and the two groups were statistically significant ( t value was -2.449, P<0.05). The duration of 100 ml·kg -1·d -1 enteral feeding and adequate enteral feeding (150 ml·kg -1·d -1) in the observation group [(24.63±9.42) days, (29.75±10.15) days] were significantly shorter than those in the control group [(33.90±2.73) days, (35.13±9.29)days], and the two groups were statistically significant ( t value was-4.621, P<0.01; t value was -2.362, P<0.05). The weight of the observation group was higher than that in the control group at the time of discharge ( t value was 4.677, P<0.05). Conclusion:Oropharyngeal colostrum administration can reduce gastric retention times, shorten the adequate enteral feeding time, promote growth and development in very low birth weight neonate and extremely low birth weight neonate.But it had not been proved to reduce the incidence of related infection indicators.
ABSTRACT
Objective To study the value of lung ultrasonography (LUS) in the diagnosis of pneumothorax in critically ill neonates.Method The neonates admitted to our NICU and suspected to have pneumothorax were prospectively enrolled from June 2017 to December 2018.All eligible infants received both LUS examination and chest X-ray.The characteristics of LUS imaging was analyzed based on the chest X-ray which was used as the golden standard for the diagnosis of pneumothorax.The sensitivity,specificity,positive predictive value and negative predictive value of LUS is computed.The duration of LUS and chest X-ray were compared.The outcome and complications were also observed.Result Fifty neonates with suspected pneumothorax were collected.Among them,pneumothorax was confirmed with chest X-ray in 31 neonates (62.0％).Ultrasound signs of pneumothorax included absence of lung sliding (100％),absence of B lines (100％),stratosphere sign (100％) were observed in all of the 31 neonates.Presence of lung point was also observed in 90.3％ of the patients.The sensitivity,specificity,positive predictive value,negative predictive value and X-ray coincidence rate of LUS in the diagnosis of pneumothorax were 100％.LUS and chest X-ray examination took (5.6 ±5.1) min and (20.1 ± 12.2) min,respectively,the difference was statistically significant (P ＜ 0.05).All 31 infants with pneumothorax survived.15 infants underwent closed thoracic drainage after emergency thoracic puncture or aspiration assisted by LUS.No postoperative complications occurred.Conclusion LUS showed high accuracy,sensitivity and specificity in detecting pneumothorax in critically ill neonates.It is simple to operate and can guide clinical rescue more promptly and quickly.
ABSTRACT
Objective To investigate the association between rs4458044 site of corticotropin releasing hormone receptor 1 (CRHR1) polymorphism and persistent pulmonary hypertension of the newborn (PPHN).Methods Eighty-five blood specimens were collected from newborns with PPHN in Affiliated Hospital of Jining Medical University between March 2012 and March 2018,and 50 blood specimens were collected from healthy newborns as controls.The basic clinical data,clinical laboratory results,distribution of CRHR1 (rs4458044) polymorphism were retrospectively analyzed by t-test andx2 test.Results No significant difference existed in gender,gestational age,birth weight and 1 minute Apgar score between newborns with PPHN and the normal controls (all P ＞ 0.05).Significant difference existed in auxiliary ventilation time and maximum oxygenation index between newborns with PPHN and the normal controls (all P ＜ 0.05).Gene frequency of CRHR1 (rs4458044) GG,CG and CC gene types in newborns with PPHN and controls was 2.35％,43.53％,54.12％ and 50.00％,38.00％,12.00％,respectively.The CG/CC gene type was significantly higher in newborns with PPHN than the normal controls (P ＜ 0.05).The CG/CC gene type newborns had a higher risk for getting PPHN than GG gene type newborns (GG gene type as reference,C G gene type OR =24.34,95％ CI:5.20-113.87,P =0.00;CC gene type OR =95.83,95％ CI:17.99-510.49,P =0.00).Auxiliary ventilation time and maximum oxygenation index of newborns carrying C allele were higher than those without carrying C allele.Conclusion CRHR1 (rs4458044) polymorphism is closely associated with PPHNs.

ABSTRACT
Objective To compare the efficacy of less invasive surfactant administration (LISA) and intubation-surfactant-extubation to CPAP (INSURE) techniques in premature infants with respiratory distress syndrome (RDS).Method From January 2016 to January 2017,premature infants with RDS admitted to our hospital were prospectively and randomly assigned into the LISA group and the INSURE group.A 6F suction tube was used to drip pulmonary surfactant (PS) into the trachea with non-invasive respiratory support in the LISA group.INSURE technique and endotracheal intubation with surfactant administration were used in the INSURE group.The following indicators were examined:the time needed for intubation,the change of percutaneous oxygen partial pressure and the incidence of bradycardia during administration,regurgitation after administration,oxygen therapy duration,mechanical ventilation duration,re-administration of PS and apnea.Secondary indicators included the incidences of pneumothorax,pulmonary hemorrhage,neonatal necrotizing enterocolitis (NEC),intraventricular hemorrhage (IVH),bronchopulmonary dysplasia (BPD),preterm retinopathy (ROP),and periventricular leukomalacia (PVL).Result A total of 145 cases were included including 76 in LISA group and 69 in INSURE group.The gestational age was 27～34 weeks.The birth weight was (1 650±480) g.No statistically significant differences existed between the two groups on the time needed for intubation,the change of percutaneous oxygen partial pressure,mechanical ventilation duration,oxygen therapy duration,the incidence of bradycardia,re-administration of PS,apnea and other complications (P＞0.05).Statistically significant differences existed in the incidence of regurgitation (46.1％ in LISA group vs.29.0％ in INSURE group),mechanical ventilation within 72 hours (13.2％ in LISA group vs.27.5％ in INSURE group) and the incidence of BPD (6.6％ in LISA group vs.17.4％ in INSURE group) (P＜0.05).Conclusion Compared with INSURE,LISA technique is effective for the treatment of RDS and reduce invasive ventilation duration and the occurrence of BPD.
ABSTRACT
Objective To study the relationship between the lung ultrasonography and the chest X-ray and to study the value of lung ultrasonography score (LUS) in evaluating the effect of pulmonary surfactant (PS) on respiratory distress syndrome (RDS) of newborn.Method Preterm infants admitted to the neonatal intensive care unit of our Hospital from January 2016 to December 2017 and diagnosed with RDS were prospectively studied.LUS examinations were performed prior to,and within the first 6～12 hours after surfactant administration,chest X-rays were also performed at the same time so as to evaluate the effects of surfactant replacement therapy and the correlation between the lung ultrasonography and the chest X-rays.Lung ultrasonography findings at a total of six sites,with three sites in each lung were scored based on the presence of normal finding,the amount of B-lines and subpleural consolidations.Result A total of 45 preterm infants with RDS were enrolled.The cases of X-ray grades Ⅰ,Ⅱ,Ⅲ and Ⅳ before PS administration were 5 cases,21 cases,12 cases and 7 cases respectively.The scores of LUS 0～6,7～12,13～ 18 were 5 cases,37 cases and 3 cases respectively,and the median of LUS was 10 points.Chest X-ray grades Ⅰ,Ⅱ,Ⅲ and Ⅳ within 6～12 hours after PS administration were 18 cases,17 cases,8 cases and 2 cases respectively.LUS of 0～6,7～12,13～18 were 21 cases,20 cases and 4 cases respectively.The median of LUS after PS was 7 points.LUS after PS application was significantly lower than that before PS application (P＜0.001).The LUS was positively correlated with the grades of X-ray before and after surfactant administration (before surfactant administration r =0.688,P＜0.001,after surfactant administration r =0.777,P＜0.001).Conclusion LUS is positively correlated with the grade of chest X-ray and might enable an early detection of the surfactant replacement therapy effects in RDS.Further studies are necessary to define the role of LUS in this field.
