Objective To analyze the prevalence of developmental dysplasia of the hip (DDH) in Tianjin,and to establish early screening of DDH in China.Methods System of health care for maternity and children in Tianjin were used to perform early ultrasound-screening program for DDH during the first 6weeks of life.The infants with abnormal conditions or suspected ultrasound results were transferred to Tianjin hospital.All the infants were clinically examined by experienced pediatric orthopaedic physician.Anteroposterior pelvic X-rays were taken for suspected infants to make a definite diagnosis.Results Hip ultrasound examinations were performed for 94 443 infants between December 26,2009 and December 25,2010.The 136 cases (165 hips) were suspected as DDH and 168 cases (200 hips) were diagnosed as DDH by ultrasound.All of them were transferred to Tianjin hospital.Among suspected patients,the positive signal of Ortolani or Barlow was found in 10 cases (11 hips).The DDH signal on the radiograph was positive in 73 cases (84 hips).Two hundred and fifty-one infants (295 hips) were finally diagnosed as DDH.There were 40 boys and 211 girls.Also,left hips and infants bom in autumn or winter were more often involved.The prevalence of DDH in Tianjin area was 2.66% (251/94 443).Conclusion Accurate early detection and diagnosis of DDH could be expected with the Tianjin pattern of preliminary screening,secondary screening and definite diagnosis.Careful clinical examination and X-ray are important for diagnosis.

Objective:To understand the status quo of neonatal palliative care attitude of nurses in neonatal intensive care unit (NICU) and analyze the influencing factors, in order to provide reference and direction for hospital management to improve the neonatal palliative care attitude of NICU nurses.Methods:A total of 237 NICU nurses in 9 hospitals in Shijiazhuang, Hebei Province were selected by cluster sampling method from November to December 2021, and the questionnaire was conducted using General Data Survey, Neonatal Palliative Care Attitude Scale (NiPCAS), the Jefferson Scale of Empathy (JSE) and Coping with Death Scale (CDS). And analyze the results.Results:The total score of the NICU nurses′ neonatal palliative care attitude was 89.35 ± 18.86. The average score of each dimension from high to low was belief, work experience, resources, organization, and obstacle; and the total score of neonatal palliative care attitude was positively correlated with empathy ability ( r=0.653, P<0.01) and death coping ability ( r=0.597, P<0.01), in addition the factor of barrier was negatively correlated with empathy and death coping ability ( r=-0.602, -0.526, both P<0.01) Multiple linear regression analysis showed that educational background, whether nursing dying infants, frequency of attending hospice nursing education in hospitals, empathy ability and death coping ability were the influencing factors of neonatal palliative care attitude, which could explain 47.3% of the total variation. Conclusions:NICU nurses′ neonatal palliative care attitude was generally at a moderate level, and affected by five factors such as education. It is suggested that hospital management should provide to improve empathy ability and death response ability as the premise of personalized, diversified education training support, multiple ways, multi-level improve its empathy ability and death coping ability, improve neonatal palliative care attitude, and then improve the quality of nursing service.
