Clinical effects of bi-level positive airway pressure and heated humidified high flow nasal cannula ventilation as initial treatment for premature infants with respiratory distress syndrome / 中国新生儿科杂志

Objective:To compare the efficacy and safety of bi-level positive airway pressure (BiPAP) ventilation and heated humidified high flow nasal cannula (HHHFNC) ventilation as initial respiratory support for premature infants with respiratory distress syndrome (RDS).Methods:From January 2019 to June 2021, premature infants [gestational age (GA) 28~35 weeks)] with grade Ⅰ to Ⅲ RDS admitted to Suining County People's Hospital were prospectively enrolled. The infants were randomly assigned into BiPAP group and HHHFNC group. The clinical characteristics, ventilation efficacy and complications were analyzed.Results:A total of 33 infants were in BiPAP group and 32 in HHHFNC group. No significant differences existed between the two groups in the following items: the frequency of apnea within 24 h of ventilation, FiO 2 and PaCO 2 at 24 h, the use of pulmonary surfactant (PS), the incidence of non-invasive ventilation failure within 72 h, non-invasive ventilation duration and the age achieving total enteral nutrition. HHHFNC group had lower score in premature infants pain profile (PIPP) than BiPAP group at 24 h of non-invasive ventilation [4 (3, 6) vs. 8 (6, 11), P<0.001]. No significant differences existed in nasal injury, pneumothorax, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia and mortality rate between the two groups ( P>0.05). Conclusions:As the initial treatment for premature infants with grade Ⅰ to Ⅲ RDS, BiPAP and HHHFNC has similar rates of non-invasive ventilation failure within 72 h,non-invasive ventilation duration and adverse events. HHHFNC may ease the pain of the infants.

Medical Antibiotic Nanosilver Dressings Using for Wound Covering after Circumcision for Phimosis / 中华医院感染学杂志

OBJECTIVE To study the results of medical antibiotic dressings-nanosilver using for the wound covering after circumcision for phimosis.METHODS Two hundred patients were randomly classified into two groups,test and control groups.For the patients of test group,the wounds were covered with nanosilver dressing moist with normal saline.For the patients of control one,the wounds were covered with vaseline dressings.The exudation,pain sensation and healing conditions were compared.RESULTS There was a decreased pain sensation in the test group.The nanosilver dressings were more easily to be removed from the wounds with little exudation and pain for the patients comparing with the controls(P

Vacuum Blood Sampling and Its Clinical Application / 中华医院感染学杂志

OBJECTIVE To summarize and analyze of various consequences caused by clinical vacuum blood sampling. METHODS The data taken from 4000 cases after with vacuum blood sampling were analyzed. RESULTS The unqualified rate of vacuum blood sampling apparatus was 0.1%. There were 12 defect blood sampling cases, and there was no puncture hurt, and infection. CONCLUSIONS Internationally standardized vacuum blood sampling is safe and reliable. A strict guideline applied in vacuum blood sampling is able to control medical cross infections.
