Objective:To explore the attitude of clinical nurses toward vital sign monitoring and analyze its influencing factors.Methods:From May to July, 2020, clinical nurses from three Class Ⅲ general hospitals in Liaocheng City were selected by convenient sampling and surveyed using a general information questionnaire, the Chinese version of the Vital Signs Monitoring Attitude Scale, and the Chinese version of the NASA Task Load Index (NASA-TLX) . A total of 747 questionnaires were collected in this study, and 721 of them were valid, accounting for an effective recovery rate of 96.5%.Results:The total score of the 721 clinical nurses' attitude toward vital signs monitoring was (56.48±6.72) . The results of multivariate analysis showed that working years, department, and workload were the influencing factors of clinical nurses' attitude toward vital signs monitoring ( P<0.05) . Conclusions:The positive attitude of clinical nurses toward vital monitoring needs to be improved, and nursing managers can start from human resource allocation to reduce their workload, encourage them to perform vital sign monitoring timely and properly, and identify changes in patients' conditions early.

Objective To investigate the risk factors of hyperbilirubinemia in late preterm infants. Methods The clinical data of 815 late preterm infants (449 males and 366 females) from 25 hospitals in Beijing were collected from October 2015 to April 2016, including 340 cases(41.7％) with hyperbilirubinemia (hyperbilirubinemia group), and 475 cases without hyperbilirubinemia (control group). The clinical data of two groups were compared, and the maternal factors influencing hyperbilirubinemia in late preterm infants were analyzed with logistic regression. Results There were no significant differences in gender ratio (M:F 1.39 vs. 1.12, t=1.811,P=0.172)and birth weight[(2502.6±439.6)g vs. (2470.2±402.9)g,χ2=2.330,P=0.127)]between two groups. The incidence rates of hyperbilirubinemia in infants of 34 wks, 35 wks and 36 wks of gestational age were 22.9％(87/174), 35％(119/300) and 42.1％(143/341) respectively (χ2=1.218,P=0.544). The multivariate logistic regression analysis indicated that the maternal age(OR=1.044,95％ CI:1.010-1.080,P=0.011)was independent risk factor and multiple births(OR=1.365,95％CI:0.989-1.883,P=0.048), premature rupture of membranes(OR=2.350,95％ CI:1.440-3.833,P=0.001), cesarean section(OR=1.540,95％CI:0.588-4.031,P=0.014)were risk factors for hyperbilirubinemia in late preterm infants. Conclusions The incidence of hyperbilirubinemia in late preterm infants is relatively high. Maternal age, multiple births, premature rupture of membranes and cesarean section are risk maternal factors related to hyperbilirubinemia in late preterm infants.

Objective:To study the respiratory morbidity and the risk factors of respiratory complications in late-preterm infants.Methods:The data of 959 late-preterm infants in 21 hospitals in Beijing from October 2015 to April 2016 were collected.These infants were divided into the respiratory morbidity group (237 cases) and the control group (722 cases) according to whether they had short-term respiratory morbidity after birth.Clinical data of the two groups were compared.Results:Among the 959 late-preterm babies, 530 were male and 429 were female.Two hundred and thirty-seven cases (24.7%) developed short-term respiratory morbidity after birth.Infectious pneumonia developed in the most cases (81 cases, 8.4%), followed by transient tachypnea (65 cases, 6.8%), amniotic fluid aspiration (51 cases, 5.3%), and respiratory distress syndrome (24 cases, 2.5%) successively.All the infants recovered and discharged.There were no differences between gender and maternal age between 2 groups (all P>0.05). Compared with the control group, more late-preterm infants were delivered by cesarean section (73.4% vs.59.7%, χ2=14.43, P<0.001) and the 1-minute Apgar score was lower [(9.41±1.66) scores vs.(9.83±0.53) scores, t=5.40, P<0.001] in the respiratory morbidity group.The differences were statistically significant.There were more cases with maternal complications in the respiratory morbidity group that in the control group (66.7% vs.58.6%, χ2=4.877, P=0.027), but no difference in various complications between 2 groups was observed ( P>0.05). In the respiratory morbidity group, the most frequent complications were maternal hypertension and preeclampsia (27.8% vs.22.6%, χ2=2.728, P=0.099). There were no differences between 2 groups in gestational age, birth weight and birth length (all P>0.05). There were more infants small for gestational age and large for gestational age in the respiratory morbidity group than in the control group (18.8% vs.14.1%, 6.3% vs.2.4%, χ2=8.960, P=0.011). The duration of hospitalization of the respiratory morbidity group was significantly longer than that of the control group [(9.00±4.42) d vs.(6.82±4.19) d, t=6.676, P<0.001] since the infants with respiratory morbidity needed to be hospita-lized. Conclusions:Respiratory diseases occur in about 1/4 of late-preterm infants.Infants who are delivered by cesarean section and whose mothers are complicated with the maternal hypertension and preeclampsia should be monitored closely.Respiratory support should be provided for infants not appropriate for gestational age who are more likely to suffer from respiratory diseases, so that they can successfully pass through the transition period.
