Objective To explore the feasibility of high concentration potassium cbloride infusion by micro pump through peripheral vein together with fluid infusion.Methods 160 patients were divided into the observation group A and B (each with 40 patients) and the control group(80 patients).For the control group,only high concentration potassium chloride was infused by micro pump through peripheral vein,high concentration potassium chloride pumped through peripheral vein together with 5％ sodium chloride and dextrose injection were adopted in the observation group A.High concentration potassium chloride pumped through peripheral vein together with medication liquid were adopted in the observation group B.The rate of pain and phlebitis in three groups were observed.Results The rate of pain and phlebitis decreased significantly in the observation groups compared with those of the control group.There was no significant difference in the rate of phlebitis between the observation group A and B.Conclusions High concentration potassium chloride infusion by micro pump through peripheral vein together with fluid infusion are more effective to alleviate pain,reduce the rate of phlebitis,and can change the kind and drip rate of the fluid based on the condition of the patients.

Objective:To explore high-risk factors of respiratory distress syndrome (RDS) and to compare the clinical efficacy of calf pulmonary surfactant (PS) combined with budesonide suspension and poractant alfa injection in the treatment of RDS in premature infants.Methods:A retrospective analysis was conducted. Preterm infants who were born in the obstetrics department of Liaocheng People's Hospital and admitted to the neonatal intensive care unit (NICU) within 24 hours from July 2016 to July 2020 were enrolled. The clinical data of these patients including perinatal conditions, clinical features, therapeutic regimens of PS and outcomes were collected and analyzed. According to the diagnostic criteria of neonatal respiratory distress syndrome (NRDS), premature infants were divided into NRDS group and non-NRDS group. First, the clinical data of the two groups were compared to analyze the related factors of NRDS. Then the related factors of NRDS were confirmed by Logistic regression analysis. In addition, according to the trapeutic regimens of PS, the children were divided into calf PS combined with budesonide suspension group and poractant alfa injection group, and the efficacy of the two PS was compared.Results:① A total of 1 690 preterm infants were included, including 297 preterm infants were diagnosed with NRDS which accounted for 17.6% of live preterm infants. There were significant differences in gender, gestational age (GA), birth parity, birth weight (BW), asphyxia of newborn, caesarean section, premature rupture of membrane, placental abruption, gestational diabetes and father's smoking addiction (maternal exposure to smoke during pregnancy) between NRDS group and non-NRDS group (male: 71.0% vs. 59.0%; GA: < 28 weeks was 4.1% vs. 0.1%, 28 weeks ≤ GA < 34 weeks was 70.0% vs. 29.9%, 34 weeks ≤ GA < 37 weeks was 25.9% vs.70.0%; birth parity: 2 (1, 3) vs. 2 (1, 3); BW: < 1 000 g was 4.1% vs. 0.4%, 1 000 g ≤ BW < 1 500 g was 31.3% vs. 6.5%, 1 500 g ≤ BW < 2 500 g was 51.5% vs. 58.9%, 2 500 g ≤ BW < 4 000 g was 12.8% vs. 33.1%, BW≥4 000 g was 0.3% vs. 1.1%; asphyxia of newborn: 50.8% vs. 14.6%; caesarean section: 71.7% vs. 65.0%; premature rupture of membrane: 66.7% vs. 42.2%; premature rupture of fetal membranes: 11.4% vs. 5.2%; gestational diabetes: 12.1% vs. 7.0%; father's smoking addiction: 80.8% vs. 71.5%, all P < 0.05), but there was no significant difference in prenatal use of dexamethasone (DEX) between NRDS group and non-NRDS group (80.1% vs. 84.1%, P > 0.05). Binary multivariate Logistic regression analysis showed that GA, gender, cesarean section, premature rupture of membranes, gestational diabetes, father's smoking addiction and neonatal asphyxia were the risk factors of RDS [odds ratio ( OR) and 95% confidence interval (95% CI) were 0.621 (0.557-0.693), 2.043 (1.478-2.825), 1.365 (1.036-1.797), 0.697 (0.506-0.961), 3.223 (1.906-5.449), 1.836 (1.261-2.673), 3.596 (2.622-4.933), all P < 0.05]. ② A total of 160 patients diagnosed with grade Ⅲ/Ⅳ NRDS were included to analyze the efficacy of PS. Among them, 42 cases were treated with calf PS combined with budesonide suspension, and 118 cases were treated with poractant alfa injection. Compared with the poractant alfa injection group, the total oxygen consumption time of the calf PS group was shorter [days: 9.0 (5.0, 19.0) vs. 13.0 (6.0, 26.0)], the hospitalization expenses were lower [ten thousand Yuan: 3.46 (2.88, 5.18) vs. 4.58 (3.08, 6.06)], and the incidence of bronchopulmonary dysplasia (BPD) was lower (11.9% vs. 28.8%), with statistically significant differences (all P < 0.05). Conclusions:In addition to GA, gender, cesarean section, premature rupture of membranes, gestational diabetes, and neonatal asphyxia, the father's smoking addiction (maternal smoke exposure during pregnancy) is an important risk factor of RDS in premature infants. The efficacy of prenatal use of DEX for prevention of RDS in preterm infants is affected by many factors, such as prenatal smoke exposure, timing of use, multiple fetuses, etc. Calf PS combined with budesonide suspension is better than poractant alfa injection in reducing the incidence of BPD.
