Study on knowledge, attitudes and practices of pulse oximetry among pediatric healthcare providers in China and their influencing factors / 中华实用儿科临床杂志

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Expert consensus on clinical application of pulse oximetry in children / 中华实用儿科临床杂志

Hypoxemia is a common complication of pneumonia, asthma, and bronchopulmonary dysplasia in children.Rapid identification of hypoxemia is of great significance for the disposal and management of critical children.Pulse oximetry is recognized by the World Health Organization as the best way to monitor hypoxemia in children, and it can monitor pulse oxygen saturation noninvasively and continuously.Based on the related literature at home and abroad, combined with the clinical needs of pediatrics, the " Expert consensus on clinical application of pulse oximetry in children" is formulated to improve the understanding of pediatricians and nurses on the application in pediatric clinical practice, principle, operation techniques, and limitations of pulse oximetry.

Correlation between severity of gastroesophageal reflux cough and degree of gastroesophageal reflux disease / 中华儿科杂志

Objective@#To explore the correlation between the severity of gastroesophageal reflux cough and degree of gastroesophageal reflux.@*Methods@#A cross-sectional investigation was carried out. Data of 174 cases of chronic cough were collected in Children's Hospital of Fuzhou from March 2009 to December 2016. The esophageal 24 hours pH value dynamic monitoring was used to detect gastric acid reflux index. Cases with abnomal results were divided into mild, moderate and severe groups according to severity of reflux and that of day and night cough symptoms, respectively. They were also divided into infant (1-3 years old), preschool (4-6 years old), and school age (>7 years old) groups according to age. Comparative analysis between groups by chi-square test and rank sum test were performed. Correlation analysis was used to analyze the correlation between cough severity and gastroesophageal reflux index.@*Results@#A total of 174 patients with chronic cough, including 115 males and 59 females, aged from 1 to 15 years with an average age of (8.5±2.3) years, and (1.6±0.8) years of disease duration were enrolled. Among them, 129 cases (74.1%) were positive for esophageal reflux test and 45 cases (25.9%) with no obvious pathological gastroesophageal reflux. Patients with positive esophageal reflux test were divided into severe (n=37, 28.7%), moderate (n=23, 17.8%), and mild (n=69, 53.5%). There was no significant difference in the distribution of gastroesophageal reflux in each age group. (The proportions of mild, moderate and severe reflux in infants were 45.0% (9/20), 25.0% (5/20), and 30.0% (6/20), respectively. The proportions of mild, moderate and severe reflux in preschool children were 53.3% (32/60), 16.7% (10/60), 30.0% (18/60), respectively. The proportions of mild, moderate and severe reflux in school age children were 57.1% (28/49), 16.3% (8/49), 26.5% (13/49), respectively χ2=1.204, P=0.877). There was no correlation between age group and gastroesophageal reflux (r=-0.065, P=0.489).The severity of nighttime cough was positively correlated with percentages of distal esophagus pH≤4 in time, recumbent pH≤4 in time, and DeMeester score<14.72 (r=0.689, 0.621, and 0.707 respectively, all P<0.05). There was no statistically significant correlation between the severity of nighttime cough symptoms and percentage of standing pH≤4 in time (r=0.113, P>0.05). There were no statistically significant correlation between the severity of daytime cough and all gastroesophageal reflux markers (all P>0.05).@*Conclusion@#The severity of nocturnal symptoms of gastroesophageal reflux cough is related to the degree of gastroesophageal reflux, to which clinical pediatricians should pay attention.

Comparison of the risk factors for asthma in children between urban and rural areas in Fuzhou City / 中华儿科杂志

<p><b>OBJECTIVE</b>To explore the prevalence and the different risk factors for asthma in children between urban and rural areas in Fuzhou, Fujian province.</p><p><b>METHOD</b>The epidemiological survey of asthma in 0-14 years old children was conducted from October 2009 to October 2010 between Fuzhou urban and rural areas in Fujian province. The investigation subjects were selected in urban and rural areas by phased stratified random cluster sampling. The 2010 third national epidemiological survey questionnaire of children with asthma was used for screening for possible patients. Diagnosis of asthma was confirmed by physical examination. The children with asthma were designated as the positive cases, while non asthmatic children who were age, gender, ethnic, and living environment matched with asthmatic patients were designated as negative control. Comparison of the prevalence of asthma in children between Fuzhou urban and rural areas was performed. The influencing factors of asthma were analyzed and screened by the regression equation model of two element Logistic regression.</p><p><b>RESULT</b>Totally 12 235 questionnaires of children with asthma and allergic disease screening were issued and 11 738 questionnaire were sent back (6 221 were male and 5 517 were female). The return rate was 95.9% in urban Fuzhou; 648 children were diagnosed as asthma. The prevalence of asthma in male was 6.48% and female children was 4.44% (comparison of the prevalence of gender χ(2) = 23.267, P < 0.001) in urban areas . A total of 6 000 questionnaires of children with asthma and allergic disease screening were sent out and 5 860 were responded (male children 3 228, female children 2 632). The recovery rate was 97.7% in rural Fuzhou; 135 children with asthma was diagnosed. The prevalence of asthma in male was 2.73%and female children and was 1.79%. Adding protein supplement before 6 months (OR = 1.908, 95%CI:1.233-2.959), the use of antibiotics in the treatment of asthma (OR = 14.541, 95%CI:8.920-23.705), furniture materials (non wood) (OR = 2.432, 95%CI:1.563-3.785) were the main risk factors of children with asthma in urban. Adding protein supplement before 6 months(OR = 3.021, 95%CI:1.357-6.711), the use of antibiotics in the treatment of asthma(OR = 14.784, 95%CI:3.842-56.885), the use of coal as fuel (OR = 63.339, 95% CI: 7.993-501.943), domesticated livestock (OR = 13.659, 95% CI:1.342-139.068), the family smoking before and after birth (OR = 6.226, 95%CI:2.674-14.495) and chemical fiber pillow (OR = 3.638, 95%CI:1.241-10.666) were the main risk factors of children with asthma in rural areas.</p><p><b>CONCLUSION</b>The prevalence of children with asthma in urban areas was higher than that in rural areas. The prevalence of asthma in male children was higher than in female children. Adding protein food supplement before 6 months, the use of antibiotics and non solid wood furniture material were the main risk factors in children with asthma in urban areas.
