Objective:To explore the status and influencing factors of nurses′ cognitive ability of nursing interruptions in operating room.Methods:From March to May 2020, convenient sampling was conducted, a questionnaire was used to investigate the cognitive ability of operating room registered nurses in some provinces and cities in China. The influencing factors were analyzed by single factor analysis and multiple stepwise linear regression analysis.Results:Finally, 2 827 questionnaires were collected from 1 municipality directly under the central government and 15 provinces, involving 42 municipal and county hospitals. The nurses′ cognitive ability of nursing interruptions in operating room scored 105.73 ± 13.39, which was in the middle level. A total of 2 427 (87.37%) operating room nurses thought it necessary to receive training on nursing interruptions, but only 796 (28.16%) nurses had received training on nursing interruptions. Multiple stepwise linear regression analysis showed that different job categories ( B=-0.714, P<0.001), whether to pay attention to nursing interruptions ( B=5.449, P<0.001), the frequency of experience nursing interruptions ( B=-1.916, P<0.001)and whether to participate in the training of nursing interruptions ( B=-4.806, P<0.001) were the influencing factors of operating room nurses' cognitive ability of nursing interruptions. Conclusions:The operating room nurses' cognitive ability of nursing interruptions is in the middle level. The current situation of training is not good, but the training demand is high. Managers should strengthen the systematic training of nurses on nursing interruptions, especially those with junior nurses in operating room, to improve nurses' attention and cognitive ability of nursing interruptions.

Objective: To investigate the effect of FOCUS(F:find; O:organize; C:clarify; U:understand; S:select)-PDCA on reducing the adverse event rate caused by junior nurses. Methods: A historical control design was used, traditional method to manage adverse events among junior nurses from January to June 2017. Interdisciplinary team combined with FOCUS-PDCA courses was established from July to December 2017. In the course problems were found and analyzed, the present procedures and standard were issued and improved. And these data were summarized and analyzed to improve the quality of management continuously. Results: Before applying the FOCUS-PDCA model, the total incidence of adverse events caused by junior nurses, bachelor′s degree or above, nurse practitioners, and working career of 1-3 years were respectively as follows: 42.66%(285/668), 46.67%(112/240), 40.54%(105/259), 51.61%(176/341). After using this model, the above four indicators were 33.04%(229/693), 33.33%(84/252), 27.04%(73/270), 38.97%(136/349) respectively. There were significant differences before and after the FOCUS-PDCA (χ²=4.20-13.39, P<0.01 or 0.05). Conclusions Multidisciplinary team-based FOCUS-PDCA management reduces the adverse event rate caused by junior nurses and improves the quality of management continuously.

Objective:To explore the MRI features of neonatal deep cerebral arterial infarctions.Methods:The medical and MRI datas of 23 neonates with deep cerebral arterial infarctions from January 2011 to December 2018 in Beijing Children′s Hospital, Capital Medical University were retrospectively analyzed. Both 11 males and 12 females with ages between 1-28 d were recruited and MRI were performed within 2-20 d after symptom onset. The MRI featurs including location, morphology, signal characteristics, enhancement features and other accompanied signs were reviewed.Results:A total of 15 cases with arterial infarction and 8 cases with complication of purulent meningitis were identified. The median age at presentation were 2 d and 7 d respectively. The unilateral involvement were demonstrated in all neonates with arterial infarctions. Among them, 11 had deep infarcts and the main branch of the middle cerebral artery was involved in 4 neonates. MRI showed slightly hypo-intensity on T 1WI and slightly hyper-intensity on T 2WI with indistinct boundary and focal punctate hyper-intensity on T 1WI and hypo-intensity on T 2WI. In 8 cases secondary to purulent meningitis, unilateral involvement was found in 5 cases and bilateral involvement in 3 cases. All cases showed hypo-intensity on T 1WI and hyper-intensity on T 2WI with indistinct boundary. Among them, 7 cases were heterogeneous, with small cystic changes which appeared as slightly hyper-intensity on T 1WI and slightly hypo-intensity on T 2WI peripherally, as well as nodular or patchy restricted diffusion. Marked swelling of the lesion was found in 6 cases. Multiple patchy or ring enhancement was revealed in 5 cases. Iso-intensity and restricted diffusion in posterior horn of the lateral ventricle were found in 2 cases. Restricted diffusion in frontotemporal subarachnoid space was found in 5 cases. One case showed subdural effusion. Conclusion:Neonatal deep cerebral arterial infarctions have certain characteristic appearance on MRI. Lesions secondary to purulent meningitis can be bilateral involvement with heterogeneous MRI intensities, and different period of infarction signs could be found concurrently. MRI is beneficial to the differential diagnosis.

Objective:To analyze the diagnosis and treatment of neonatal neuroblastoma (NB) by summarizing its clinical characteristics.Methods:This study retrospectively recruited 14 neonates with NB in Beijing Children's Hospital (National Center for Children's Health) from February 1, 2015, to February 1, 2020. Medical records and follow-up data as of February 29, 2020, were collected, and clinical staging based on International Neuroblastoma Staging System, risk grouping based on American Childhood Oncology Group risk grouping system, diagnosis, treatment, and prognosis were analyzed. According to whether surgical treatment was performed in the neonatal period or not, these subjects were divided into surgical and non-surgical groups. A descriptive statistical analysis was used for data analysis.Results:(1) Neonates with NB accounted for 0.063% (14/22 006) of the total number of newborns admitted to the hospital during the same period. The 14 cases were all full-term aged 15 d (8 h-23 d) at admission. Tumors were found in seven cases in prenatal examinations, while others presented with shortness of breath (three cases), abdominal distension (two cases), fever (one case), and dysuria and difficult defecation after birth (one case). (2) The primary tumor sites included the adrenal gland (eight cases), posterior mediastinum (three cases), retroperitoneum (two cases), and sacrococcygeal (one case). Three cases had extensive diffuse liver metastasis at admission. (3) Except for two cases who refused to examine, the serum neuron-specific enolase of 12 cases was 57.2 ng/ml (35.9-158.3 ng/ml) during hospitalization, and the urine vanillyl-mandelic acid creatinine of four cases was 2 304.940 (685.748-9 595.314). (4) Primary tumor sites were found in 14 cases by imaging examination. Bone scanning was performed in three cases, including one with a concentrated shadow of the right sacroiliac joint and two with no abnormalities. Ten cases underwent bone marrow aspiration and all with normal results. (5) Of the ten neonates received surgery (the surgical group), nine had the primary tumor wholly removed, without chemotherapy after the operation, and the tumor-free survival period was 19 months (1-45 months). One case (case 5) had a substantial primary tumor that could not be completely resected. The patient underwent a second surgery five months after the first operation due to disease progression and received postoperative chemotherapy. The child had stopped chemotherapy for 24 months and survived without a tumor. (6) In the non-surgical group (cases 11 to 14), the tumor in case 11 who refused chemotherapy shrank spontaneously after discharge, and the patient survived for 20 months with the tumor. The parents of the case 12 withdrew treatment during hospitalization, while the primary tumor and metastases disappeared after discharge, and the specific tumor markers gradually decreased to normal levels. The patient has been tumor-free survived for 25 months. Case 13 received mediastinal tumor resection and chemotherapy during infancy. At the end of the follow-up, chemotherapy had been stopped for 12 months, and the patient survived without a tumor. Case 14 withdrew treatment and died. (7) Among the ten cases in the surgical group, one patient's pathological result indicated a composite tumor, while the others were low differentiated neuroblastoma. There was no MYCN gene amplification, 1p36 deletion, or 11q23 deletion in the ten cases. (8) Among the ten children in the surgical group, nine were in stage 1, and one was in stage 4S (case 5). Nine cases were classified into extremely low-risk groups, while the other was in the low-risk group. The four cases in the non-surgical group could not be grouped by risk. Conclusions:Clinical manifestations of neonatal NB are often atypical. NB in stage 4S might resolve spontaneously, and expectant observation may be considered. The overall prognosis of neonatal NB is generally good, but further researches are needed.
