ABSTRACT
Objective To explore the effect of doctor-nurse integrated ward round performed in the training of professional nurses′ core competence.Methods 18 nurses trained for core competencies in ICU and hemodialysis room were selected as research objects.All nurses were trained with doctor-nurse integrated ward round for one year.The professional knowledge, skills and clinical comprehensive ability of all nurses were tested before and after training.Results After doctor-nurse integrated ward round, the scores of professional knowledge, skills and clinical comprehensive ability of professional nurses were significantly higher than that of before training (P<0.05).Conclusion Doctor-nurse integrated ward round can improve the core competencies of professional nurses.
ABSTRACT
Objective To discuss the X-ray and CT manifestations of keratocystic odontogenic tumour(KCOT)in mandible,to im-prove the diagnostic accuracy of the disease.Methods The X-ray and CT features of KCOT(n=25)in mandible,which were proved by surgery and pathology,were retrospectively analyzed.Results The KCOT,including solitary tumor(n=23)and multiple tumor (n=2),mainly displayed unilocular or multilocular in shape with distinct sclerosing margin.Disruption of the adjacent cortex was de-tected in 7 cases,growth along the long axis of mandible in 18 cases,compression and displacement of the adjacent teeth in 21 cases, resorption of bevel of roots in 2 cases.Conclusion Most lesions of KCOT in mandible have characteristic manifestation in X-ray and CT findings,which is helpful for diagnosis and differential diagnosis.
ABSTRACT
Objective To discuss the X-ray and CT findings of pulmonary air leak in neonates and to improve the early diagnostic ability.Methods The supine anteroposterior chest films of 33 neonates with pulmonary air leak were retrospectively analyzed.A-mong them,spiral CT scanning was performed in 5 cases.Radiographic follow-up was made in 30 cases.Results Pulmonary intersti-tial emphysema was found in 2 cases,pneumomediastinum in 4 cases,simple pneumothorax in 14 cases.Pulmonary interstitial em-physema combined with pneumomediasfinum was detected in 2 cases,with pneumothorax in 4 cases.Pneumomediastinum combined with pneumothorax was displayed in 3 cases.Pulmonary interstitial emphysema combined with pneumomediastinum and pneumotho-rax was found in 4 cases.Among them,medial pneumothorax was shown in 26 side,lateral pneumothorax in 9 side.Conclusion X-ray radiography is the main method for the diagnosis of pulmonary air leak in neonates,and CT can further define the location,range and extent of the disease.
ABSTRACT
Objective To investigate the correlation between CT grading and prognosis of hypoxic-ischemic encephalopathy(HIE),and with the diagnostic value of CT findings and followed-up.Methods 49 neonates from 1 month to 1 year with HIE whose CT findings and followed-up results and clinic were retrospectively analyzed.Results Among 49 cases,the clinical follow-up showed that the hypodense foci induced by HIE were absorbed and disappeared completely within 1～3 months after birth.10 neonates presented external hydro-cephalous at 1～3 months after birth and then that was absorbed after 6 months to 1year of age.In 3 months,the part poor moderate HIE in the neonates might cause the leukomalaria,while severe HIE might cause the cerebral malaria and atrophy within 1 month after birth.Conclusion The prognosis of HIE is closely related to the degree of abnormal manifestations on CT.Intracranial lesions were favorable in the mild HIE,good in the moderate ones and bad in the severe ones.If there were bleeding in ventricles,the prognosis would be more poor.
ABSTRACT
Objective To assess the value of low dose CT scanning applied in nasal sinus examination. Methods 100 cases were divided into two groups,including youth group and adult group,with 50 cases for each group.After scanned by standard dose(150mAs),all the patients were scanned with low dose. Those in youth group were scanned with 40mAs and 25mAs,and the others in adult group were scanned with 50mAs and 30mAs.CT images were evaluated by three doctors using blind method.The image quality was evaluated according to 3 grades:normal image,image with mild artifact,and image with serious artifact and the results were analyzed statistically. Results The CTDlw of low-dose CT scanning was obviously lower than that of standard dose(P
