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.
Objective To observe the retinal function of infa nts with retinopat hy of prematurity (ROP). Methods A total of 78 infants (156 ey es) aged from 4-5 months underwent full-field flash electroretinogram (ERG) examination. The am p litude and implicit time of a-and b-wave of ERG were detected to evaluate the i nfants' retinal function. Seventy-eight infants (156 eyes) included 33 healthy a nd full-term infants (66 eyes), 25 healthy premature children (50 eyes), and 20 infants (40 eyes) with ROP. Results Obvious ERG waveforms were recorded in all the fullterm and healthy premature children. Amplitude of combined b-wave wa s 388.7 mu;V in full-term infants and 336.7 mu;V in healthy premature children, whi c h was 64.4% and 55.6% of that of the healthy adults respectively. In infants wit h ROP, ERG was nonrecordable in 20 eyes (50％); amplitude of combined b-wave was 183.8 mu;V in the other 20, whose implicit time delayed obviously compared with that of fullterm infants. The amplitude of ERG of healthy premature infants de c reased significantly compared with that of the full-term infants. Conclusions Retina keeps growing after birth. ERG of healthy full-term chi ldren is not as developed as those of adults. The progress of retinal maturation in infants with ROP is slower than that in the full-term infants. ERG examination is an effecti ve method in evaluating retinal function of infants with ROP.
Objective To investigate the degree of retinal developmen t in pret erm infants and compare the electroretinograms between preterm and fullterm in fants. Methods Flash electroretinogram (ERG) were obtained wit h contact lens el ectrodes in one eye from ten preterm infants (10 eyes) and twenty full-term inf a nts (20 eyes) in seven days after birth. The rod cell, cone cell, maximal combi nation, oscillatory potentials, and 30 Hz flicker responses were recorded. Results Compared with the full-term infants, the implicit time of rod cell respon s e (t=3.216，P=0.003) was longer and the amplitudes were lower (t=6.0 50，P=0.000) in the preterm infants; the difference of implicit time of maximal response was not significant (t=0.465，P=0.650; t=1.068，P=0.295), while th e amplitudes dec reased (t=6.584, P=0.000; t=6.649, P=0.000). The a- and b-wav e implicit time of cone response was not differed much between the two groups (t=0.077, P=0.939; t=0.935,P=0.358); the amplitudes was obvious lower in preterm group (t =3 .417，P=0.002；t=6.310，P=0.000); the difference of implicit t ime of 30 Hz flic ker betw een the two groups was not significant (t=3.745，P=0.001). The difference of b/a value of maximal combination response was not obvious between the two groups ( t=0.215, P=0.831). Conclusions The development of retinal function is slower in preterm infants than that in full-term ones．
Objective To explore the maternal and neonatal outcomes of different types of severe preeclampsia premature birth. Methods The pregnant outcomes of 142 patients with severe preeclampsia premature birth (the study group) were compared with 311 patients with spontaneous premature birth (the control group). Singleton pregnancy was divided into three stages by gestational age: very early premature birth (28-31+6 weeks), moderate premature birth (34-36+6 weeks) and mild premature birth (32-33+6 weeks). Multiple-pregnancy was divided into two stages: lt;34 weeks of gestation group and ≥34 weeks of gestation group. Results he rates of antenatal care and the average birth weight of trial group were much lower than those of control group. he rates of cesarean delivery and complications of trial group were much higher than those of control group. he total neonatal mortality and neonatal intensive care unit (NICU) hospitalization rate of singleton pregnancy in trial group was much higher than that of control group (Plt;0.05). In very early premature birth, neonatal outcomes were particularly bad, but there was no diference between trial group and control group. In moderate premature birth and mild premature birth, the incidences of neonatal pneumonia and the aspiration syndrome of trial group were higher than those of control group, and the duration of NICU hospitalization was longer in trial group than in control group. he incidences of heart failure and postpartum hemorrhage in twin pregnancy combined with severe preeclampsia were particularly high. Conclusion Severe preeclampsia signiicantly afects fetal growth and perinatal outcomes; the average birth weight in each trial group of singleton pregnancy is much lower than that of control group. In moderate premature birth and mild premature birth, the neonatal adverse outcomes of trial group are much higher than those of control group. he total neonatal mortality and NICU hospitalization rate of singleton pregnancy in trial group is much higher than that of control group. In very early premature birth, morbidity and mortality of the newborn is closely related to gestational age. Women of multiple-pregnancy complicated with severe preeclampsia require more concerns about health care in order to prevent heart failure and postpartum hemorrhage.
ObjectiveTo systematically review the effectiveness and safety of atosiban in the treatment of threatened premature labor. MethodsWe electronically searched databases including The Cochrane Library, EMbase, PubMed, CBM, CNKI, WanFang Data and VIP for randomized controlled trials (RCTs) on atosiban for threatened premature labor from inception to October 2012. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 11 RCTs involving 2 542 cases of threatened preterm labor were included. The results of meta-analyses showed that atosiban was superior to β2 adrenergic receptor agonists in effectiveness (48 h:OR=1.33, 95%CI 1.06 to 1.66, P=0.01; 7 d:OR=1.36, 95%CI 1.12 to 1.65, P=0.002) and maternal tolerability (48 h:OR=1.65, 95%CI 1.34 to 2.06, P < 0.01; 7 d:OR=1.65, 95%CI 1.34 to 2.02, P < 0.01), but its effectiveness was similar to calcium antagonists (48 h:OR=0.94, 95%CI 0.55 to 1.60, P=0.82; 7 d:OR=0.92, 95%CI 0.53 to 1.60, P=0.77). There were no significant differences in gestational age (MD=0.20, 95%CI-0.16 to 0.56, P=0.27), the incidence of cardiovascular adverse effects in the mother's body (OR=0.07, 95%CI 0.01 to 1.05, P=0.05), birth weight (MD=-13.20, 95%CI-77.84 to 51.44, P=0.69), and the incidences of asphyxia (OR=2.08, 95%CI 0.89 to 4.87, P=0.09), sepsis (OR=0.78, 95%CI 0.54 to 1.14, P=0.20) and respiratory distress syndrome (OR=1.03, 95%CI 0.65 to 1.65, P=0.89) between the atosiban and β2 adrenergic receptor agonist groups. But its incidence of cardiovascular adverse effects in the mother's body was significantly lower than calcium antagonists (OR=0.001 4, 95%CI 0.02 to 0.82, P=0.05). ConclusionAtosiban is better than other tocolytics in controlling the uterine contraction, and it could significantly prolong gestational age, with less maternal side effects and more tolerability. It is safer than other tocolytics in the treatment of threatened premature labor. It could be used as a first-line drug for the treatment of acute preterm contractions because of its high specificity in the uterus.
ObjectiveTo measure and analyze the tortuosity of retinal veins in neonatal and premature infants quantitatively. MethodsA retrospective clinical study. The fundus images of the left eyes were selected from 30 healthy neonates and 30 premature infants without retinopathy of prematurity underwent RetCam screening. There were 16 premature infants with a history of oxygen inspiration. The tortuosity of superior temporal veins, inferior temporal veins, superior nasal veins, inferior nasal veins was measured separately using a self-developed computer program. Pearson correlation analysis was used to analyze the relationship between tortuosity of retinal veins and birth weight, gestational age and correct gestational age. ResultsIn full-term neonatal infants, the vascular tortuosity of the nasal veins was significantly higher than the temporal veins (t=5.73, P < 0.01), while the superior veins and inferior veins showed no significant difference (t=0.39, P > 0.05). There was no correlation between vascular tortuosity of temporal (r=0.179, -0.175) or nasal veins (r=0.055, 0.345) with birth weight or gestational age (P > 0.05). In premature infants, the vascular tortuosity of the nasal veins was also significantly higher than the temporal veins (t=5.00, P < 0.01), no significant difference was found between the superior veins and inferior veins (t=0.39, P > 0.05). The vascular tortuosity of temporal veins of premature infants was negatively correlated with birth weight (r=-0.375, P < 0.05); however, no significant correlation was found with gestational age (r=-0.296, P > 0.05). The vascular tortuosity of the temporal retinal veins of premature infants with a history of oxygen inspiration was significantly higher than premature infants without a history of oxygen inspiration (t=2.517, P < 0.05), though no significant difference was found between the nasal veins (t=-0.261, P > 0.05). The vascular tortuosity of the temporal and nasal retinal veins of premature infants was both higher than neonate, but was not statistically significant (t=0.88, 1.50; P > 0.05). ConclusionsThe vascular tortuosity of the temporal veins was greater than the nasal veins in both full-term and premature infants, though no significant difference was found between superior and inferior veins. The vascular tortuosity of temporal veins of premature infants increased as birth weight decreased. The vascular tortuosity of the temporal retinal veins of premature infants with a history of oxygen inspiration was higher than premature infants without a history of oxygen inspiration.
ObjectiveTo observe the effect of breastfeeding on the incidence of retinopathy of prematurity (ROP).MethodsA retrospective clinical study. From June 2017 to December 2019, 1256 eyes of 628 premature infants who were born in Ningbo Women and Children's Hospital and were screened for ROP were included in the study. Among them, there were in 325 males (650 eyes) and 303 females (606 eyes). According to the feeding situation, premature infants were divided into breastfeeding (research) group and formula feeding (control) group, with 390 cases of 780 eyes and 238 cases of 476 eyes, respectively. The changes in the retina of the fundus of the two groups of premature infants during the observation period were compared. The qualitative data comparison between groups was performed by the χ2 test; the quantitative data comparison was performed by the two independent sample t test.ResultsThe sex ratio of premature infants in the study group and control group (χ2=0.217), birth weight (t=0.728), gestational age at birth (t=0.351), Apgar score at birth (t=0.816), oxygen inhalation time (t=0.427), were compared with the length of stay in the neonatal intensive care unit (t=1.580), the difference was not statistically significant (P＞0.05). Among the 390 cases in the study group, 108 cases (27.7%, 108/390) and 282 cases (72.3%, 282/390) were with or without ROP, respectively; in the 238 cases in the control group, 86 (36.1%, 86/238) were with ROP, 152 (63.9%, 152/238) cases were without ROP. There was a statistically significant difference in the incidence of ROP between the two groups (χ2=4.934, P=0.026). Among the 108 cases of ROP in the study group, 50 (12.8%, 50/108), 35 (9.0%, 35/108), 23 (5.9%, 23/108) cases were in stage 1, 2 and 3, respectively. Among the 86 ROP cases in the control group, stages 1, 2 and 3 were 25 (10.5%, 25/86), 40 (16.8%, 40/86), and 21 (8.8%, 21/86), respectively. In the comparison of ROP staging between the two groups, the difference in stage 1 was not statistically significant (χ2=0.754, P＞0.05), and the difference in stage 2 and above was statistically significant (χ2=11.400, P＜0.05).ConclusionBreastfeeding may reduce the incidence and severity of ROP.
Objective To systematically review the effect of adjustable fortification on feeding during preterm hospitalization. Methods We searched Cochrane Library, Web of Science, PubMed, China National Knowledge Infrastructure, Wanfang, Chongqing VIP for clinical controlled trials about adjustable fortification in premature infants. The retrieval time limit was from the establishment of each database to September 2022. We selected studies according to inclusion and exclusion criteria, extracted data and assessed their quality, then used RevMan5.3 for analysis. Results A total of 5 randomized controlled studies, 1 historical controlled study and 3 case-control studies were included, including 750 premature infants. Meta-analysis results showed that compared with the standard fortification group, the differences of body weight growth rate [mean difference (MD)=1.61 g/(kg·d), 95% confidence interval (CI) (0.73, 2.49) g/(kg·d), P=0.0003], body length growth rate [MD=0.15 cm/week, 95%CI (0.01, 0.29) cm/week, P=0.04], head circumference growth rate [MD=0.19 cm/week, 95%CI (0.06, 0.31) cm/week, P=0.003], incidence rate of necrotizing enterocolitis [relative risk (RR)=0.23, 95%CI (0.07, 0.75), P=0.01] were statistically significant in the adjustable fortification group. There was no significant difference in the incidence of feeding intolerance between the two groups [RR=0.58, 95%CI (0.31, 1.11), P=0.10]. Conclusion Adjusted fortification has a positive role in promoting the physical development of premature infants without increasing the incidence of feeding intolerance and necrotizing enterocolitis. When the growth of premature infants is poor after using standard fortification, adjustable fortification can be considered. However, due to the lack of included literature, more large sample, high-quality randomized controlled studies are needed in the future to further verify the feeding effect of adjustable fortification on premature infants.
Kangaroo mother care has reduced mortality and morbidity in preterm and low birth weight infants and has many benefits, such as promoting breastfeeding. Based on the current evidence in China and internationally, we developed clinical practice guidelines for kangaroo mother care in preterm and low birth weight infants using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE), and proposed 34 recommendations for 20 key questions. Our goal is to promote the appropriate implementation of kangaroo mother care in clinical practice.
