RESUMO
Objective To analyze the application of multi‐slice spiral CT and 3D airway reconstruction technique on obstruc‐tive sleep apnea syndrome (OSAS) of pharyngeal soft tissue and upper airway stenosis .Methods Selected 92 patients with OSAS in our hospital as the observation group and another 92 healthy persons were selected as control group ,all patients achieved multi‐slice CT and 3D airway reconstruction technical inspections ,counted and compared their pharyngeal soft tissue and upper airway stenosis .Results Airway stenosis of tongue back ,and hypopharynx retro‐palatal of control group were more narrow compared with the control group(P<0 .05);the observation group′s pharyngeal soft tissue was more thick than the control group ,so as the length and width(P< 0 .05) .Conclusion Multi‐slice spiral CT and 3D airway reconstruction technique can effectively share pharyngeal soft tissue and upper airway stenosis of patients with OSAS .
RESUMO
OBJECTIVE To investigate the pharyngeal opportunistic pathogens and their drug resistance related to different duty of the hospital staff,in order to improve the control and prevention of hospital infection.METHODS Totally 302 pharyngeal samples were cultured and isolated,and the tests of antibiotic susceptibility were(performed) for isolated strains to 15 kinds of antibiotics by using of the paper diffusion method.RESULTS The(isolated) rate of the opportunistic pathogens among hospital staff was 30.13%,higher in nurses(41.32%) than in technicians(20%,P
