Objective To compare the effects of three different crystalloid solutions on arterial blood lactate concentration and acid-base balance during orthotopic liver transplantation (OLT) without veno-venous bypass. Methods Ninety ASA Ⅱ-Ⅳ patients with end-stage liver disease of both sexes (78 males, 12 females) aged 16-67 yrs weighing 45-87 kg undergoing OLT were randomly allocated to one of 3 groups ( n = 30 each): group Ⅰ received normal saline (NS); group Ⅱ received lactated Ringer's solution (LR) and group Ⅲ acetated Ringer's solution (Plasma A, Baxter) (PA). The crystalloid was infused at a rate of 6-8 ml?kg-1?h-1. Colloid, albumin, RBC and whole blood were infused based on BP, CVP and Hb concentration. The arterial pH, BE and lactate concentration were measured before anesthesia (T0 baseline) , before cross-clamping of the portal vein (T1) at 30 min and the end of anhepatic phase (T2,T3) , 5 and 30 min after unclamping of the portal vein (T4,T5) and at the end of surgery (T6). Results There was no significant difference in the amount of crystalloid, colloid and blood products infused during operation among the 3 groups. Arterial pH decreased significantly at T1 (immediately before anhepatic phase) as compared to the baseline value at T0 and the low pH was maintained until the end of operation. BE was significantly decreased during anhepatic phase (at T2 and T3 ) . The blood lactate was increasing during operation and was 3 times that of baseline value at the end of operation. However there was no significant difference in arterial pH, BE and lactate concentration among the 3 groups.Conclusion In OLT without venovenous bypass, blood lactate increases progressively but the lactated Ringer's solution does not have any effect on the blood lactate concentration.

Objective Orthotopic liver transplantation (OLT) without bypass is technically simpler butimposes additional stress and strain on already compromised ciroulatory function and milieu interieur. The purposeof this study was to investigate the changes in arterial blood concentrations of glucose and lactate during OLTwithout bypass. Methods Eighty patients (66 male, 14 female) aged 12-67 yr weighing 40-130 kg undergoingOLT without veno-venous bypass for terminal liver cirrhosis (40 patients), liver cancer (28 patients), hepato-lenticular degeneration (5 patients), polycystic liver (3 patients) and severe hepatitis (4 patients). Nine patientswere classified as ASA physical status Ⅱ, thirty-nine patients as ASA Ⅲ, thirty patients ASA Ⅳ and two patientsASAV. Anesthesia was induced with midazolam 2 mg, fentanyl 10-15?g?kg~(-1), propofol 1 .0 - 1 .5 mg?kg~(-1) andpancuronium 0. 15 mg?kg~(-1) and maintained with isoflurane inhalation and intermittent i. v. boluses of fentanyl,midazolam and pipecuronium. The patients were mechanically ventilated after intubation, P_(ET) CO_2 was maintained at32-35 mm Hg. No fluid containing glucose was infused during operation. Radial artery and internal jugular veinwere cannulated for BP and CVP monitoring. ECG, MAP, CVP, SpO_2, P_(ET)CO_2, temperature and urine outputwere continuously monitored during operation. Blood samples were taken from artery before anesthesia (T_0 ), beforecross-clamping of portal vein (T_1), 30 and 60 min during anhepatic phase (T_2, T_3), 5 and 30 min afterunclamping of vena cava before the unclamping of portal vein (T_4, T_5 ) and at the end of surgery (T_6 ) fordetermination of blood glucose and lactate concentrations. Blood lactate was determined only in 50 patients whoreceived no lactated but acetated Ringer's solution during operation. In 70 patients blood samples were obtainedfrom hepatic vein after unclamping of portal vein and before the end of exsanguination from the hepatic vein fordetermination of blood glucose and lactate. Results No patient developed hypoglycemia during operation. Bloodglucose increased slightly before cross-clamping of portal vein (T_1) and during anhepatic phase (T_2, T_3) comparedwith the baseline value before anesthesia (T_0 ) (P

OBJECTIVE To explore the affection of protective constraint on infection among psychiatric inpatients and it′s preventive methods.METHODS A retrospective study of infection among psychiatric patients was carried by medical records investigation.Inpatients in states of protective constraint and non-constraint in confining units of psychiatric department were divided into study group and control group.Case-control study was carried up on rate of hospital infection and rate of infection of parts of body between groups.RESULTS The infective rate of study group was significantly higher than control one,in which,infective rates of lower respiratory tract,urinary tract,dermatological and mucous parts of study group were significantly higher than control group.CONCLUSIONS Protective constraint for psychiatric patients is one of risk factors of hospital infection,to which should be pay attention,and preventive methods might be taken.

Objective To investigate the incidence,etiology,diagnosis,treatment and outcome of uterus rupture.Methods From January 1999 to May 2013,clinical data of 67 cases with uterine rupture in Woman's Hospital,School of Medicine,Zhejiang University were studied retrospectively.Results A total of 67 cases of uterine rupture with 21 +2--39 +2 gestational weeks out of 128 599 deliveries were recorded giving an incidence of uterine rupture was 0.052 1 ％ (67/128 599).Cesarean scar rupture were found in 59 cases (88％,59/67) and noncesarean scar rupture were found in 8 cases (12％,8/67).The causes of uterine rupture include 60 cases of scar uterus (59 cesarean scar cases and 1 myomyectomy scar case),2 cases of assisted delivery operation trauma,2 cases of malformed uterus,3 cases of unknown causes (all with artificial abortion history).Non obstructive dystocia and improper oxytocin use were found to be related with uterine rupture.Fifty-two cases of cesarean scar spontaneous incomplete rupture were found and repaired during repeated cesarean delivery without maternal and fetal complications.The remaining 15 cases need emergency rescue operation for fetal distress or dead fetus,severe acute abdomen,prepartum or postpartum vaginal bleeding even maternal hypovolemia; 6/15 uterine rupture cases were diagnosed with the history,clinical symptoms and signs,3/15 cases with ultrasonic found dead fetus in the peritoneal cavity before exploratory laparotomy and 6 cases were diagnosed just during laparotomy.Hysterectomy was done in 10/15 cases and uterine repair in 5/15 cases; there was no maternal death and 12 perinatal fetal death (5 cases of mid-late pregnancy termination for deformed fetus) of the 15 uterine rupture cases.One case with hysterectomy was complicated with stress pancreatitis and dysfunction of liver and kidney and discharged 20 days after operation,the remaining 14 cases were discharged 5-7 days postpartum.One case with repaired malformed uterus got pregnancy 4 years later and delivered a 2 000 g healthy baby by cesarean section at gestational age of 33 +4 weeks.Conclusion Uterine scar caused by caesarean section or other operations became the leading cause of uterine rupture,assisted delivery operations,history of intrauterine manipulation and uterine malformations were the predisposing risk factors of uterine rupture.

Objective The prevalence rate, related factors and clinical characteristics of postpartum depression were studied in order to promote obstetrician′s understanding of the disease, and resort to preventive and therapeutic measure earlier. Methods Two hundred and ten puerpera were selected from September to November 1998 for mood study by self rating depression scale, self rating anxiety scale, Hamilton depression scale, and self made questionnaires. Results The prevalence rate of postpartum depression was 37 14% (78/210), of which, 91 03% (71/78) was mild, and 8 97% (7/78) moderate. In addition, 10 48% (22/210) of women got anxiety after delivery. The symptoms, including decreased activity, difficulty in thinking, problems in decision making, difficulty in doing things, feeling of uselessness and hopelessness were chief complaints of postpartum depression patients. Bad social behavior and mood controlling, inadequate psychological preparation for delivery, lack of knowledge of delivery were closely correlated to the onset of postpartum depression, which are the risk factors of postpartum depression. Conclusions Postpartum depression is a spiritual and psychological obstacle with relatively high prevalence rate. Bad social psychological factors can bring out and aggravate postpartum depression. It is important to carry out prenatal psychological care and to propagate the knowledge of delivery, to find out and cure of postpartum depression as soon as possible.

0 1, for both). Conclusion Decreased expression of placental EGFR was found in women with PIH, and that may play a role in the pathogenesis of PIH.
