C4以下脊髓损伤（SCI）患者肺功能中用力呼气高峰流速等多项指标明显低于胸腰段的患者，其主动排痰能力明显下降，常导致肺部感染及窒息等合并症。及时排出呼吸道分泌物，可减少呼吸系统合并症。体位排痰、雾化吸入、早期站立训练等有助于排痰及残存肺功能的提高。

ObjectiveTo investigate the risk factors of nosocomial infection(NI) of patients with spinal cord injury(SCI),strengthen the prevention and control measures and reduce the NI rate.MethodsClinical data of 967 patients hospitalized in our hospital from Jan 2002 to Dec 2004 were analyzed retrospectively.ResultsThe nosocomial infection rate of SCI patients was 30.3%(293 cases),the most common infection sites were urinary tract,respiratory tract,gastrointestinal tract and wound.The major pathogen was gram-negative bacteria.The infection rate of patients with cervical SCI was significantly higher than patients with thoracic and lumbar SCI(P<0.01).ConclusionSCI patients are susceptible to NI;rehabilitation at early stage should performance to improve living ability of patients and decrease the NI rate.

ObjectiveTo investigate the influencing factors of nosocomial infection in rehabilitation department of children in our hospital.MethodsThe clinical data including infection part,infection time,immunoglobulin and length of stay of 532 cerebral palsy(CP) children was retrospectively investigated.ResultsSixty-one CP children got nosocomial infection.The nosocomial infection rate was 11.47%,the most common infection sites was respiratory tract(86.89%).March,April and November were the seasons easy to occur nosocomial infection.The levels of immunoglobulin of the infected children were lower than the normal children.ConclusionThe lower level of immunoglobulin,longer hospitalization,ventilation obstructed indoor,and season change maybe the important factors which leading a higher nosocomial infection rate for CP children.
