RESUMEN
Objective To evaluate the clinical effect of emergency pelvic external fixation in hemodynamically unstable patients with pelvic fracture.Methods The clinical data of 56 hemodynamically unstable patients with pelvic fracture from January 2008 to December 2013 were selected.The changes of hemoglobin,mean arterial pressure,heart rate,serum lactate,urine volume,norepinephrine dosage before and after surgery for 24 h were compared and analyzed.Results Compared with those before surgery,the levels of hemoglobin,mean arterial pressure,serum lactate,urine volume,heart rate after surgery for 24 h were significantly improved:(109 ± 12) g/L vs.(69 ±22) g/L,(87.8 ±6.5) mmHg (1 mmHg =0.133 kPa) vs.(55.8 ± 7.7) mmHg,(6.3 ± 5.1) mmol/L vs.(10.8 ± 6.6) mmol/L,(35.9 ± 9.9) ml/h vs.(17.6 ± 8.4) ml/h,(84.2 ± 15.4) times/min vs.(146.4 ± 12.1) times/min,and the norepinephrine dosage was significantly reduced:(0.8 ± 0.2) μ g/ (kg· min) vs.(2.2 ± 0.8) μ g/ (kg· min).The differences had statistical significance (P ＜ 0.05 or ＜ 0.01).Conclusion Bedside pelvic external fixation can rapidly improve shock symptom in hemodynamically unstable patients with pelvic fracture,which is safe and efficient.
RESUMEN
Objective To evaluate DSA feature, the value, efficacy and side effect, survival time of microcathereter superselective catherization intervenetional treatment on liver metastases cancer. Methods 60 cases with liver metastases cancers were cannulated through common femoral artery by seldinger technique. If the artery was lack, second radiography was given through superselective hepatic artery. On the base of DSA feature of liver metastases, all the patients were divided into two groups: superselective- catherization group and nonsuperselective-catherization group. There were 30 patients in each group respectively. Microcathereter was used in the former to "embed" the tumor vessel and "siphonal" technique was used in the later. Compared the changes of the two groups in volume, the deposit of iodized oil in liver matastases after treating one month and the changes of ALT, ALB, TBIL in blood. The efficacy and side effect were compared in two groups. The survival time and DSA feature of using microcathereter were also analyzed. Results The DSA feature and efficacy of superselective-catherization group was better than that of non-superselective-catherization group, the side effect was mild and the survival time was longer than the former. Conclusion Microcathereter superselective catherization to treat liver metastases cancer has better efficacy, artery radiography, lighter side effect and can prolong the survival time.
