ABSTRACT
Objective To investigate the risk factors for death within 30 days of stroke associated pneumonia(SAP) in elderly patients of the intensive care unit (ICU).Methods Clinical data of 116 patients with SAP who were admitted to ICU were reviewed.The predicting factors of death within 30 days were analyzed through variable analysis method.Results The hospitalization periods of the SAP group and control group were (27±8) d and (12±5) d,the difference was statistically significant(t =1 1.30,P =0.002).The most common pathogenic bacteria in SAP were Klebsiella pneumoniae,Bauman Acinetobacter,Escherichia coli,and gram negative bacteria.There was significant difference between the two groups in term of mortality rate(37.9％(44/ 116) of SAP group,22.0％ (22/100) of control group,x2 =6.423,P =0.011).Logistic regression analysis showed that basic diseases(OR =2.778,95％ CI:1.205-6.401),high CRUB-65 score (OR =1.978,95％ CI:0.871-11.098),lower Glasgow coma score(GCS) (OR=3.601,95％CI:0.244-9.477),bucking(OR=3.020,95％CI:1.305-10.603),mechanical ventilation(OR=2.654,95％CI:1.176-5.990),shock(OR=2.636,95％ CI:1.164-5.969) and high plasma CRP level(OR=2.333,95％CI:1.046-5.206) were risk factors for SAP (all P＜0.05).In Cox regression analysis,a GCS score of ＜ 9 was an independent risk factor for 30 d mortality of patientswithSAP(HR=7.23,95％Cl:2.24-20.11,P=0.001).Conclusion SAP is one of the serious complications of the elderly hospitalized for the acute stroke in the ICU,which may affect the prognosis of the patients.
ABSTRACT
Objective To discuss the risk factors of ventilator-associated pneumonia (VAP) in intensive care unit(ICU).Methods From January 2008 to June 2010,the clinical data of 145 patients with mechanical ventilation over 48 hours in ICU were analyzed prospectively,and the effect was observed.Results There were a total of 53 patients with VAP,and the incidence was 36.6％ (53/145).Thirty-three cases died,and the fatality rate was higher than that in non-VAP patients [62.3％ (33/53) vs.30.4％ (28/92)],and there was significant difference (P ＜0.05).Related factors analysis results showed that indwelling gastric tube,the use of antiacids,mechanical ventilation time,nutritional status,age ≥ 60 years and chronic diseases were the risk factors of VAP (P ＜ 0.05 or ＜ 0.01).Conclusion VAP has many risk factors and higher fatality rate in ICU,and comprehensive prevention measures should be adopted to prevent the occurrence of VAP.
ABSTRACT
Objective To study the clinical topography of lateral ligament of the rectum in the relation to surgical procedures in rectal carcinoma. Method Twenty-three pelvises(12 males,11 females)harvested from embalmed cadavers were studied by topographic dissection. Results The lateral rectal ligamem were identiffed bilaterally in all cadavers between the rectum and visceral fascia.Unilateral middle rectal arteries was found in 8 cadavers and bilateral arteries was found in 2 cadavers.The rectal branches from the pelvic plexus were uniformly constant structure within lateral ligament of the rectum.Conclusion The lateral rectal ligament is located between rectum and visceral fascia.The cleavage between visceral fascia and pelvic plexus is the appropriate plane for lateral rectal dissection of rectal cancers.
