Mechanicalventilation in newborns can be divided into invasive mechanical ventilation and non-invasive me-chanical ventilation. In order to reduce invasive ventilation-induced lung injury, more and more non-invasive ventilation patterns have been used clinically. Early application of nasal intermittent positive pressure ventilation (NIPPV) has become the main mode of non-invasive ventilation in many neonatal intensive care units (NICU). At the same time, the combination with selective pulmonary surfactant can reduce the incidence of chronic lung disease. This article reviews the use and prospect of non-invasive respiratory support modes which include continuous positive airway pressure (CPAP) and bi-level CPAP mode (BiPAP) such as SiPAP and NIPPV. Some modes which are in the research stage were also reviewed including synchronized nasal intermittent positive pressure ventilation, neurally adjusted ventilatory assist and non-invasive high-frequency oscillatory ventilation.

Objective To study the incidence of complications and the influence on early postnatal growth and development in very low birth weight infant(VLBWI) fed by breast milk.Methods From January 1, 2010 to December 31, 2013, 351 VLBWIs, who were appropriate for gestational age and hospitalized in Neonatal Intensive Care Unit of Tianjin Central Hospital of Obstetrics and Gynecology, were included in this study after exclusion of those with small for gestational age, large for gestational age, severe perinatal asphyxia at birth, withdrawing treatment or death, and mixed feeding infants.The group of formula-fed infants (FFI) were 168 VLBWI admitted between January 1, 2010 to December 31, 2011 and the group of breast milk-fed infants (BFI) were 183 VLBWI admitted between January 1, 2012 to December 31, 2013.For BFIs, we added human milk fortifier when oral intake reached 100 ml/kg.All subjects were followed up to 40 weeks of corrected gestational age.We compared the incidence of complications and infantile growth and development from birth to 30 days old between the two groups.Independent sample t-test and Chi-square test were applied for statistical analysis.Results The incidence of feeding intolerance in FFIs was higher than that of the BFIs [27.4％ (46/168) vs 15.3％ (28/183)], so was the incidence of necrotizing enterocolitis [14.9％ (25/168) vs 5.5％ (10/183)] (x2=7.683 and 8.651, both P ＜ 0.05).The incidence of nosocomial infection, retinopathy of prematurity and bronchopulmonary dysplasia in FFI and BFI were 34.5％ (58/168) vs 33.3％ (61/183), 15.5％ (26/168) vs 10.4％ (19/183), and 11.3％ (19/168) vs 9.3％ (17/183), but none of them showed significant difference between the two groups (x2=0.055, 2.033 and 0.388, all P ＞ 0.05).Significant difference was neither found in weight gain from birth to 30 days old [(304± 137) vs (308± 123) g], height growth [(2.6± 1.1) vs (2.7± 1.2) cm] and head circumference growth [(2.5± 1.0) vs (2.4±0.9) cm] between the FFIs and BFIs (t=0.106, 0.614 and 0.485, all P ＞ 0.05).Conclusion Breast feeding is beneficial to VLBWI in decreasing the incidence of feeding intolerance and necrotizing enterocolitis without adverse effect on their early postnatal growth and development.

Objective To understand the whole situation of neonatal resuscitation in high risk deliveries.Methods Totally,3 420 neonates born from high risk pregnant mothers in Tianjin Central Obstetrics and Gynecology Hospital from September 2013 to November 2014 were recruited and divided into four groups according the needs of resuscitation,including no resuscitation group (Group A),initial resuscitation group (Group B),initial resuscitation plus bag-and-mask or T-piece ventilation (positive pressure ventilation group,Group C),tracheal intubation and/or external chest compression and/or epinephrine administation (tracheal intubation group,Group D).Variance analysis,Chi-square test and Logistic regression analysis were applied to compare the differences of clinical conditions among these groups and to analyze risk factors of tracheal intubation requirement for extensive resuscitation.Results Among the 3 420 newborns,2 360(69.0％) were assigned to Group A,565 (16.5％) to Group B,408 (11.9％) to Group C and 87 (2.5％) to Group D.Statistical differences were shown in the gestational age [(35.5 ± 4.1),(33.0 ± 4.3) and (32.1 ± 4.8) weeks],birth weight [(2 593.8 ± 663.6),(2 063.3 ± 973.9) and (1 839.0 ± 977.9) g],and the incidence of multiple births [66(11.7％),65(15.9％) and 23(26.4％)],abruptio placentae [15(2.7％),35(8.6％) and 9(10.3％)],umbilical cord prolapse [0(0.0％),2(0.5％),and 10(11.5％)],abnormal fetal heart rate in labor [28(5.0％),45(11.0％) and 46(52.9％)],prolonged labor [36(6.4％),35(8.6％),and 20(23.0％)],meconium stained liquor [32(5.7％),0(0.0％),and 8(9.2％)],and congenital anomaly [8(1.4％),12(2.9％) and 7(8.0％)] among Group B,C and D (F or x2=233.188,105.050,14.535,19.934,91.434,149.366,26.525,28.602 and 13.765,all P ≤ 0.05).Multiple regression analysis revealed that gestational age ≤ 28 weeks (OR=1.290,95％ CI:1.167-1.425),abnormal fetal heart rate in labor (OR=1.350,95％CI:1.184-6.862) and meconium stained liquor (OR=1.397,95％CI:1.051-6.825) were independent risk factors for endotracheal intubation requirement (all P ≤ 0.05).Conclusions More newborns born from high risk mothers may need resuscitation,especially for those in small gestational age,with abnormal fetal heart rate during labor and meconium-stained liquor,thus close monitoring and management are necessary.

As a high-level, applied, and specialized nursing professional, master of nursing specialist (MNS) postgraduates place great emphasis on the importance of clinical practice. Clinical practice helps to improve their clinical skills, identify clinical problems, and cultivate clinical research thinking. However, due to the late start of MNS education in China, there are still many problems in its clinical practice training, such as incomplete training programs, weak academic resources, and unclear self positioning. Based on this, this article reviews the current situation and influencing factors of clinical practice training for MNS postgraduates, and puts forward corresponding suggestions, in order to provide reference and guidance for optimizing the MNS postgraduate training program in China.

Objective:To understand the current situation of nurses′ implementation of oral care for elderly patients, so as to improve oral care practice standard and quality of oral care constantly.Methods:Using convenient sampling method, 190 nurses in the general ward of the General Hospital of Ningxia Medical University were selected as the research object from September to November 2020. The self-designed questionnaire was used to investigate and analyze the implementation of oral care among elderly patients.Results:A total of 190 questionnaires were collected in this survey, 84.74%(161/190) of the nurses reported that the hospital or department had oral care practice standard; The proportion of nurses who evaluated the oral status of elderly patients by the oral care assessment tool was 17.89%(34/190).Only 14.74%(28/190) and 16.84%(32/190) of the nurses could always set the expected rehabilitation goals and formulate the corresponding nursing plans for the oral problems of elderly patients, respectively. When the elderly patients had special oral problems, 26.32% (50/190) of the nurses would proactively communicate with doctors or search literature; the oral knowledge and oral hygiene habits of the elderly patients would be known to nurses accounting for 5.26% (10/190).Conclusions:Nurses′ cognition of oral care for elderly patients is at a low level on the structure, process and outcome.Relevant nursing managers still need to further improve the oral care operation norms and the training of nurses′ knowledge and skills, so as to continuously promote the oral health of elderly patients.

Objective:To explore the responsibilities of respiratory nurses in the management of chronic obstructive pulmonary disease (COPD) patient and the difficulties in disease management, so as to provide reference basis for formulating COPD management training strategies for respiratory nurses.Methods:Using phenomenological methodology, 14 nurses from the Department of Respiratory and Critical Care Medicine in the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan were interviewed in a personal semi-structured way from May to August 2021, and the data were sorted and analyzed according to Colaizzi 7-step analysis method.Results:Nurses′understanding of the responsibilities of COPD patient management could be summarized into five themes: dynamic monitoring and management of patients′ health, nursing decision-making of sudden changes in patients′ condition, implementation of patients′ out of hospital follow-up, promotion of improvement of patients′ self-management behavior, and cooperation among multidisciplinary team members. The difficult experience of nurses in the management of COPD patients abstracted five themes: lack of professional knowledge of COPD management, lack of clinical nursing decision-making authority, lack of human and financial support for follow-up, lack of communication skills with patients, and lack of multidisciplinary team formation in the hospital.Conclusions:Respiratory nurses have a clear understanding of the responsibilities of COPD patient management, but there are multiple difficulties in performing their responsibilities. We should pay attention to the responsibility positioning and difficulty support of nurses′ COPD management, and formulate targeted training strategies to promote the improvement of COPD nursing quality.

Objective:To evaluate the efficacy of radiofrequency thermocoagulation with CT-guided transforaminal puncture of intervertebral foramen through the superior margin of costotransverse joint for refractory post-herpetic neuralgia (PHN) in the upper thoracic segment.Methods:Thirty patients with PHN in the upper thoracic segment underwent radiofrequency thermocoagulation with CT-guided intervertebral foramen puncture. The visual analogue scale and self-rating depression scale were used to evaluate the degree of postoperative pain and mental state before and after treatment, and patients were followed by telephone or outpatient visit.Results:No infection occurred after radiofrequency thermocoagulation in all 31 PHN patients. After operation, all patients had hypoesthesia in skin of the original pain area, the pain was significantly relieved, and the mental state improved significantly. The VAS scores were 5.94±0.93, 2.74±0.69, 2.68±0.70 and 2.45±0.51 before and 3 hours, 1 week, 1 month after treatment( t=18.80, t=18.80, t=16.44, all P<0.01). The SDS scores were 58.6±12.2, 47.7±4.4, 48.1±4.8 before and 1 week, 1 month after treatment( t=6.75, t=5.86, all P<0.01). There were 13 patients with moderate or severe depression before treatment, while no patients with moderate or severe depression after treatment; only 5 patients had mild depression one month after surgery. There was no hypoxemia under nasal catheter during the operation. Intraoperative hypertension was found in 19 cases; after treatment with Urapidil (12.5 - 50.0 mg), the blood pressure was not higher by 20% of the basal blood pressure and<180/100 mmHg (1 mmHg=0.133 kPa). No pneumothorax, perioperative cardiovascular and cerebrovascular accidents occurred. Conclusion:Radiofrequency thermocoagulation with CT-guided intervertebral foramen puncture through the superior margin of costotransverse joint can effectively relieve refractory PHN of the upper thoracic segment with safety.

Objective To investigate the serum levels of homocysteine(HCY)and cystatin C(Cys-C)in patients with antineutrophil cytoplasmic antibody(ANCA)-associated vasculitis(AAV)associated renal injury,and to explore the diagnostic value of combined detection of HCY and Cys-C in ANCA-associated renal injury.Methods We selected 70 ANCA-positive patients with renal injury admitted to the Department of Nephrology in our hospital from January 2016 to January 2019.Another 48 patients with ANCA-positive but not complicated with renal injury were in simple ANCA positive group while 50 patients with physical examination who came to the hospital during the same period were in control group.Healthy patients served as the control group.By comparing the differences in the test results of different groups,the area under the curve(AUC)of each test index for ANCA-positive renal injury was determined,and the correlation and diagnostic value of combined detection of HCY and Cys-C for ANCA-related renal injury were calculated.Results The levels of HCY and Cys-C in the ANCA positive combined with renal injury group,the pure ANCA positive group,and the control group differed significantly(P＜0.05).The positive rates of HCY and Cys-C in the two groups were significantly different(P＜0.05).The sensitivity and specificity of HCY and Cys-C in combination for the diagnosis of ANCA-positive related renal injury were significantly higher than those of the above indicators alone(P＜0.05).ROC curve results showed that HCY combined with Cys-C had a better diagnosis for patients with positive ANCA and associated renal injury and a higher correlation.Conclusion HCY combined with Cys-C is closely correlated to ANCA-related renal injury,and the combined detection has a positive effect on the diagnosis of patients with ANCA-positive related renal injury,and has guiding value for the treatment of patients.

Objective:To explore the current situation of discharge preparation services for elderly patients in ClassⅢ hospitals in Ningxia Hui Autonomous Region, so as to provide a reference for optimizing implementation plans and service processes.Methods:This study was a cross-sectional study. From November 10 to 30, 2020, convenience sampling method was used to select 175 head nurses of clinical departments from 10 Class Ⅲ hospitals in Ningxia Hui Autonomous Region as the research subject. The General Information Questionnaire and Discharge Preparation Service Implementation Questionnaire were used for investigation. A total of 175 questionnaires were distributed, and 175 valid questionnaires were returned with the valid response rate of 100.00%.Results:Among 10 ClassⅢ hospitals, a total of 86.29% (151/175) departments carried out discharge preparation services for elderly patients, of which 61.59% (93/151) departments completed the screening of discharge preparation service targets within 24 to 48 hours after the patients were admitted; 25.81% (24/93) departments used standardized assessment tools; 76.16% (115/151) departments fully considered the social resources available near the home of elderly patients when formulating individualized discharge preparation services; 58.28% (88/151) departments carried out nurses collaborating with multidisciplinary teams during the implementation of discharge preparation services, and 95.36% (144/151) departments followed up discharged elderly patients.Conclusions:The overall development rate of discharge preparation services for elderly patients in ClassⅢ hospitals in Ningxia Hui Autonomous Region is at a medium to high level. There are still deficiencies in the timeliness of discharge preparation services, the use of mature assessment tools, the coordination and use of available social resources, and the communication and cooperation of multidisciplinary teams. Relevant departments and department personnel need to further perfect the implementation process and continuously improve the quality of services for elderly patients to prepare for discharge.

Objective:To construct a quality evaluation index system of discharge planning for elderly patients, so as to provide a reference basis for the evaluation of the quality of discharge planning for elderly patients.Methods:The overall research time was from August 2020 to August 2021. Taking the three-dimensional quality evaluation model as the framework, through literature review, a preliminary construction of the quality evaluation index system of discharge planning for elderly patients was established. The Delphi method was used to conduct 2 rounds of consultation with 20 experts, and finally the quality evaluation index system of discharge planning for elderly patients was determined, and the weight of each index was determined by the network analytic hierarchy process.Results:Among 2 rounds of consultation, the effective recovery rates of the questionnaires were 85.00% (17/20) and 100.00% (17/17) , the expert authority coefficients were 0.912 and 0.909, and the Kendall harmony coefficients were 0.141 and 0.134, respectively ( P<0.05) . The quality evaluation index system of discharge planning for elderly patients included 3 first-level indicators, 12 second-level indicators, and 50 third-level indicators. Conclusions:The quality evaluation index system of discharge planning for elderly patients is scientific and reliable, and can provide a reference basis for comprehensive evaluation of the quality of discharge planning for elderly patients.
