Objective To evaluate the maternal satisfaction and the clinical effect of kangaroo mother care (KMC) in preterm infants. Methods We searched PubMed, EMBASE, Ovid, Springer, CNKI, CBM and Taiwan Database of Journal Fulltext (from establishment to September 2007) and hand searched relevant conference proceedings to identify randomized controlled trials on kangaroo mother care. The quality of included trials was assessed. Meta-analyses were conducted using The Cochrane Collaboration’s RevMan 4.2 software. Results A total of 5 eligible studies were included. No significant differences were observed in infant mortality, incidence of severe infections, and psychomotor development at 12 months (corrected for age) between the KMC group and the routine therapy group (Pgt;0.05). Compared to the routine therapy group, the KMC group had lower incidences of nosocomial infection, upper respiratory tract disease at 6-month follow-up and not exclusively breastfeeding at discharge (Plt;0.05). KMC could improve mother’s sense of competence during her baby’s stay in hospital and NICU, increase infant weight at discharge, relieve mother’s feelings of worry and stress during her baby’s stay in hospital (Plt;0.05). Conclusions The currently published evidence from randomised trials supports the use of KMC in preterm infants, which is a scientific, effective and humanistic nursing model. Further multicentre and large-scale randomized controlled trials of KMC are still needed to evaluate its potential influence on infant mortality and psychomotor development.
ObjectiveTo systematically review the experience of parents caring for preterm infants after discharge from hospital. MethodsWe searched databases including The Cochrane Library, Joanna Briggs Institute Library, PubMed, EMbase, Scopus, ISI Web of Science, PsycINFO, CINAHL, CBM, CNKI and VIP from inception to May 2015, to collect qualitative studies in the experience of parents caring for preterm infants after discharge from hospital. The quality of included studies was evaluated according to JBI Critical Appraisal Tool for qualitative studies in Australia. The results were integrated by integrating methods. ResultsA total of nine studies were included. Thirty-one complete findings were grouped according to their similarities to form seven categories. These categories resulted in two synthesized findings:integration results 1:parents grow in the adaptation of their care giving roles for the preterm infants; integration results 2:they are eager and thankful for support, resource and information in this critical transition period. ConclusionHealth care workers should pay attention to the important influence of premature infants discharged from hospital on their parents. In the adaption period of premature parents, health care workers should give necessary care knowledge skills to guide the parents, to assist them to compete the role of caregivers as soon as possible and promote the healthy growth of premature infants after discharge.
ObjectiveTo systematically review the effectiveness and safety of interventions which target to improve the rate of successful extubation in preterm infants.MethodsPubMed, Web of Science, Cochrane Library, Chongqing VIP database, China National Knowledge Infrastructure, and Wanfang Database were searched for articles published from the dates of establishment of databases to August 2020, which compared different noninvasive respiratory support models or different doses of caffeine to improve the rate of successful extubation in preterm infants in randomized controlled trials. The references of included articles were also retrieved. And then a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 33 randomized controlled trials involving 4 536 preterm infants were included. Compared with nasal continuous positive airway pressure (NCPAP), high-flow nasal cannula (HFNC) reduced the nose injury rate [odds ratio (OR)=0.29, 95% confidence interval (CI) (0.15, 0.57), P=0.000 3] and the pneumothorax rate [OR=0.18, 95%CI (0.06, 0.55), P=0.003]; nasal intermittent positive pressure ventilation (NIPPV) reduced the extubation failure rate [OR=0.33, 95%CI (0.23, 0.48), P<0.000 01], the reintubation rate [OR=0.36, 95%CI (0.20, 0.65), P=0.000 7], the respiratory failure rate [OR=0.33, 95%CI (0.17, 0.64), P=0.000 9], and the pneumothorax rate [OR=0.29, 95%CI (0.12, 0.70), P=0.006]; and biphasic positive airway pressure (BiPAP) reduced the reintubation rate [OR=0.21, 95%CI (0.09, 0.46), P=0.000 1]. Compared with low-dose caffeine, high-dose caffeine reduced the extubation failure rate [OR=0.44, 95%CI (0.32, 0.60), P<0.000 01] and the bronchopulmonary dysplasia rate [OR=0.69, 95%CI (0.48, 0.99), P=0.04], but increased the rate of tachycardia [OR=1.99, 95%CI (1.22, 3.25), P=0.006].ConclusionAccording to the current evidence, compared with NCPAP, NIPPV and BiPAP could be used to improve the rate of successful extubation in preterm infants, HFNC could be used to decrease the risk of nose injury and pneumothorax; the optimal dose of caffeine should be chosen after evaluating the risk of adverse reactions such as tachycardia.
ObjectiveTo observe and analyze thyroxine levels in children with retinopathy of prematurity (ROP) and its effect on severe ROP. MethodsA retrospective clinical study. From January 2022 to December 2023, a total of 64 premature infants with severe ROP (ROP group), hospitalized in the Children's Hospital Affiliated to Zhengzhou University and with a gestational age ≤32 weeks, were included. According to a 1:2 ratio, 128 premature infants without ROP, matched for sex and gestational age, were selected as the control group. Thyroid function tests were performed 7 to 14 d after birth. The levels of thyroid-stimulating hormone, triiodothyronine, free triiodothyronine, thyroxine (T4), and free T4 (FT4) were compared and observed between the two groups. The quantitative data between groups were compared by independent samples t-test or Mann-Whitney U test; the count data were compared by χ2 test. Logistic regression was used to analyze the correlation between various variables and the occurrence of severe ROP. The predictive efficacy of the differential indicators was assessed by receiver operating characteristic (ROC) curve. ResultsCompared with the control group, T4 and FT4 levels were significantly lower in children in the ROP group, and the difference was statistically significant (t=2.572, 2.704; P=0.011, 0.008). The results of univariate logistic regression analysis showed that the Apgar scores at 1 and 5 minutes, as well as sepsis, T4, FT4, and bronchopulmonary dysplasia (BPD), were significantly associated with the occurrence of severe ROP (P＜0.05). The results of multivariate logistic regression analysis indicated that FT4 and BPD are independent risk factors for the occurrence of severe ROP (P＜0.05). The ROC curve analysis revealed that T4 had a sensitivity of 80.9% and specificity of 43.3%, while FT4 showed a sensitivity of 46.8% and specificity of 75.0%, with abnormal cutoff values set at 98.4 nmol/L for T4 and 15.65 pmol/L for FT4. ConclusionsThe T4 and FT4 level of children with severe ROP are lower than that of children without ROP in the early postnatal period. The T4 and FT4 level in the early postnatal period may have a certain correlation with the occurrence of severe ROP.
