OBJECTIVE:To observe the effects of dexmedetomidine on hemodynamics of patients underwent cardiac valve re-placement in the anesthesia induction. METHODS:92 patients underwent cardiac valve replacement were randomly divided into ob-servation group and control group,with 46 patients in each group. Both groups received routine anesthesia induction regimen of midazolam 1-2 mg/kg+ fentanyl 0.05 mg/kg+ propofol 1-2 mg/kg+ cis-atracurium 0.15 mg/kg. Observation group was additionally given dexmedetomidine 0.5 μg/kg,within 10 min with pumps,and then maintained with 0.4 μg/(kg·h)till the end of operation;control group was additionally given constant volume of normal saline with pumps. SBP,DBP,MAP,HR,cardiac output(CO), cardiac index(CI),stroke volume(SV),stroke volume variation(SVV)before anesthesia induction(T0),5 min after medication (T1),2 min after anesthesia induction (T2),1 min after intubation (T3),3 min after intubation (T4) and 5 min after intubation (T5)were recorded in 2 groups as well as OAA/S at T0 and 5 min after pumping dexmedetomidine(T1). ADR of 2 groups during anesthesia was also recorded. RESULTS:There was no significantly difference in SVV of 2 groups at T0-T5 (P>0.05);SBP, DBP,MAP,HR,CO,CI and SV of observation group at T0-T5 were all better than those of control group,with statistical signifi-cance(P<0.01);there was no statistically significant difference in OAA/S of 2 groups at T0(P>0.05),and OAA/S of observa-tion group at T1 was decreased significantly and lower than control group,with statistical significance(P<0.01). There was no sta-tistically significant difference in the incidence of ADR as cardiac arrhythmia and hypotension between 2 groups(P>0.05). CON-CLUSIONS:Dexmedetomidine can reduce the influence of anesthesia on the hemodynamics of patients underwent cardiac valve re-placement with good safety.

ObjectiveTo investigate the clinicopathological characristics of mucinous gastric carcinoma (MUC). MethodsFrom 1994 to 2001, 438 gastric cancer patients underwent operation, among them, 36 patients (8 2%) were with MUC. The clinicopathological parameters and prognosis of MUC and non MUC were analyzed retrospectively. ResultsThere were no significant differences in age, sex, tumor site and hepatic metastasis. Patients with MUC had higher rate of serosal invasion, invasive type lymph node involvement, peritoneal dissemination. Patients with MUC were of more advanced stage (stage Ⅲ and Ⅳ:MUC 88 9%,non MUC 73 9%). The 1 year and 2 year survival rate for MUC patients was lower than that for non MUC patients (50 5%?33 1% vs. 74 9%?64 7%). Conclusions The poor prognosis of MUC was correlated with frequent serosal invasion, lymph node involvement, peritoneal dissemination, and advanced stage at the time of diagnosis.
