Objective To discuss the clinical preventation and treatment of the complications induced by endotracheal intubation in SICU.Methods Retrospective analysis was used on 55 cases of intubated patients in our hospital nearly 2 years.Results The incidence of endotracheal intubation was 36.4％,pneumonia 23.6％,accidental extubation 5.5％,endotracheal ulcer 1.8％,tracheoesophageal fistula 1.8％,obstruction of tracheal catheter 1.8％,arytenoid dislocation 1.8％.Conclusion The causeof complications of endotracheal intubation in SICU were overtime intubation,tranma,excessive-pressure of the air cuff and local inflammation.Airway humidification,suitable sedation,accurate and moderate operation,extubation or tracheotomy,suitable cuff pressure and fiberoptic bronchoscopy examination could avoid such complications.

Objective To validate the theraputic efficacy of percutaneous ethanol injection(PEI) for hyperparathyroidism caused by parathyroid adenoma.Methods One case of parathyroid adenoma underwent PEI whose diagnosis was comfirmed by biopsy. The 22 gauge needle was punctured into the adenoma under CT guidance and ethanol was injected into the lesion at multiple points. Results The CT images obtained 6 months after 2 times of CT guided PEI revealed that the volume of the adenoma decreased markedly together obviously with decrease of enhancement after the injection of contrast media. The level of serum parathyroid hormone, calcium and phosphorous returned normal 2 days to 12 months after the management. The clinical manifestations improved markedly.Conclusions CT guided PEI is a minimally invasive and highly effective theraputic modality for hyperparathyroidism. It can serve as an important supplement to surgery.

Objective To understand the incidence.mortality and risk factors of ventilator -associated pneu-monia(VAP)in surgical intensive care unit among elderly patient,in order to direct the clinical prevention and treat-ment of VAP.Methods Retrospective analysis was used on 65 cases of mechanical ventilation elderly patients in our hospital nearly 3 years.Results The incidence of VAP was 66.2%.The mortality of VAP was 67.4%.The factors of long-term mechanical ventilation,high APACHE Ⅱ score,low Glasgow score and inappropriate initial antimicrobial therapy were influenced the prognosis of VAP.Conclusion The incidence of VAP can be decreased and the cure rate can be increased by some effective measures in SICU.

Objective: To study the diagnosis and treatment of primary hyperparathyroidism.Methods: The clinical data of 8 primary hyperparathyroidism patients(1992 2002) in our hospital were summarized and the references were reviewed.Results: It was found that primary hyperparathyroidism was liable to be misdiagnosed.Information on blood calcium,parathyroid hormone(PTH) and imaging may be helpful for diagnosis. Surgical resection(4 cases), anhydrous alcohol injection (2 cases), electron radiation (1 case) and internal medicine (1 case) were applied. Conclusion:Information on blood calcium,PTH and early imaging is helpful for diagnosis.Operation is the first choice of treatment, and for patients who can not tolerate surgery, anhydrous alcohol injection is an effective and safe treatment.
