ABSTRACT
Objective To investigate the effect of midazolam on cardiopulmonary function during colonoscopy.Methods From June 2014 to June 2015,214 patients underwent colonoscopy were randomly divided into two groups:109 patients in the midazolam group and 105 patients in the non-sedated group(control group).systolic blood pressure(SBP),diastolic blood pressure (DBP),heart rate (HR) and peripheral blood oxygen partial pressure (SpO2) in the two groups before and after colonoscopy were compared.Results In the midazolam group,SBP and DBP decreased more during colonoscopy than in the control group.However,the frequency with a significant change in SBP was similar in both groups.During colonoscopy,HR andSpO2 decreased more in the midazolam group compared to those in the control group.SpO2 levels returned to normal after the procedure in two groups.Conclusion Midazolam has a tolerable effect on cardiopulmonary function and may be safely used during colonoscopy.
ABSTRACT
Objective To investigate correlation study of serum hs-CRP,UA level and the correlation of dis-ease in elderly acute myocardial infarction patients , and provide a reference basis for clinical judgment for patients with illness development and prognosis prediction .Methods 40 aged patients with acute myocardial infarction pa-tients were selected as the research object ,and protionally random according to time admission the same period ran-domly selected were 40 cases of elderly patients with unstable angina pectoris ,40 cases of elderly patients with stable angina,40 cases of clinic medical normal healthy old people for controlled object .The levels of serum hs-CRP,UA and correlation was analyzed.Results The serum hsCRP,UA in the myocardial infarction group were (34.67 ±12.18)mg/L, (412.46 ±68.93)μmol/L,which in the unstable angina pectoris group were (17.21 ±8.39) mg/L,(274.19 ± 46.62)μmol/L,which in stable angina pectoris group were (5.25 ±1.40) mg/L,(297.41 ±37.43)μmol/L,which in the health group(4.96 ±1.24)mg/L,(279.64 ±34.78)μmol/L,the differences among the myocardial infarction group,unstable angina pectoris,stable angina pectoris group had statistical significance (P0.05);Different prognosis in patients with myocardial infarction hsCRP is associated with UA has positive correlation between ( P<0.05) .Conclusion Elderly acute myocardial infarction patients serum hs-CRP,UA obviously increased ,and illness development correlation ,a high level of hs-CRP,UA patients often indicates poor prognosis .
ABSTRACT
[Objective]To classify fractures of posterior malleolus by computed tomography and guide its clinical treatment.[Method]From January 2003 to October 2006,eighty-eight patients who had been treated surgically for the posterior malleolar fractures were reviewed.There were 53 males and 35 females.The mean age was 42.3 years(ranged,18～75 years).All the patients' preoperative radiograph and computed tomographic scans were reviewed,and each fracture was categorized according to the size,location and fracture line of the major fragment and the stable state of mortise.The classification was applied to treat 88 patients.[Result]On the basis of the computed tomographic images,the posterior malleolar fractures were categorized into four types.There were type Ⅰ(stable) in 23 cases,type Ⅱ(borderline) in 26 cases,type Ⅲ(big unstable posterolateral oblique) in 18 cases and type Ⅳ(medial-extension) in 21 cases.Type Ⅰ included type Ⅰ1(small shell)in 5 cases and type I2(small posterolateral oblique) in 18 cases.Type Ⅱ included type Ⅱ1(moderate posterolateral oblique without lateral-posterior dislocation of talus)in 15 cases and type Ⅱ2(moedrate postero-lateral oblique with lateral-posterior dislocation of talus)in 11 cases.All patients were followed up for an average of 31months(ranged from 12 to 48 months).According to the Baird-Jackson scoring system,the results were rated as being excellent in 62 cases,good in 13 cases,moderate in 8 cases,and poor in 5 cases,with the good-excellent rate being 85.2%.[Conclusion]Computed tomographic scans can demonstrate the pathoanatomy of the posterior malleolar fracture and provided guidance for clinical treatment.
