Objective To study effect of general anesthesia combined with epidural anesthesia on analgesia and microcirculation in patients undergoing total hysterectomy. Methods 92 patients of total hysterectomy who received therapy were selected, according to random number table,those patients were divided into the observation group (n=42) and the control group (n=48),the observation group received general anesthesia combined with epidural anesthesia, the control group were only given general anesthesia.The operation condition, hemodynamics and stress response before anesthesia(T0), at tracheal intubation(T1), after pneumoperitoneum 10min(T2), after surgery(T3), at extubation(T4) were compared,and postoperative pain (VAS) score was compared. Results There was no significant difference in operation time and fluid volume between the two groups. In the control group,the levels of mean arterial pressure (MAP), heart rate (HR) at the time of T1, T2, T3 were significantly increased(P<0.05), the levels of MAP and HR at the time of T1,T2,T3 in the observation group were lower than the control group(P<0.05). The cortisol (Cor), epinephrine (E), norepinephrine (NE) at the time of T1,T2,T3,T4 in the observation group were lower than the control group(P<0.05). Two groups of patients in the postoperative 12h, 6h, the VAS scores in the resting state and cough state were higher than the postoperative 1h(P<0.05),but the scores in the observation group were lower than the control group(P<0.05). Conclusion General anesthesia combined with epidural anesthesia is well for total hysterectomy,which can maintain hemodynamic stability during surgery, relieve stress reaction, alleviate postoperative pain, it is worthy of application and promotion.

Objective To study factors influencing injury severity of expressway traffic acci- dents. Methods Data of expressway traffic accidents involving casualties in areas around Hangzhou during 2005-2006 were collected and analyzed by non-conditional simple and multiple logistic regression analysis. Results (1) During 2005-2006, there were 220 traffic crashes involving 327 eases, of which there were 64 deaths (19.6%), 121 severe injuries (37.0%, ISS≥16 points) and 142 slight and mod- erate injuries (43.4%, 1 point≤ ISS≤15 points). (2) Non-conditional simple logistic regression analy- sis showed that risk factors significantly influencing the injury outcomes of traffic accidents included gen- der, weekday, weather, type of collision, vehicle type, driver category, purpose of vehicle use, purpose of travel and crash responsibility. (3) Non-conditional multiple logistic regression analysis manifested that influential factors were gender, type of collision, driver category and crash respensibihty. Conclu- sion Analysis of expressway traffic accidents data helps identify factors influencing injury severity of ex- pressway traffic accidents may provide suggestions for prevention or decrease of expressway traffic acci- dents.
