[Effect of epidural anesthesia on hemorheology in patients undergoing gynecological laparoscopy].

Objective: To evaluate the effect of epidural anesthesia and patient-controlled epidural analgesia (PCEA) on hemorheology and the incidence of deep venous thrombosis in patients undergoing gynecological laparoscopy.

Methods: One hundred ASA I-II patients undergoing gynecological laparoscopy were randomly allocated into 2 groups to receive general-epidural anesthesia combined with PCEA (GE group) and general anesthesia (G group). Blood samples were taken before anesthesia (T(0)), before operation (T(1)), 30 min after pneumoperitoneum (T(2)), 30 min after pneumoperitoneum cease (T(3)), and 24 and 48 h after the operation (T(4), T(5)) for hemorheological tests.

[Effect of intrathecal administration of sufentanil at different doses on bupivacaine spinal anesthesia in gynecologic laparoscopy].

Objective: To investigate the effect of sufentanil administered intrathecally at different doses on the clinical effect of bupivacaine spinal anesthesia in gynecologic laparoscopy.

Methods: Sixty patients with ectopic pregnancy undergoing elective laparoscopy (ASA class I-II) were randomized into 4 groups (groups A, B, C and D), and received spinal anesthesia with 15 mg bupivacaine and sufentanil at 0, 2.5, 5 and 7.

[Application of flurbiprofen preemptive analgesia combined with intravenous propofol anesthesia in induced abortion].

Objective: To investigate the effect of flurbiprofen preemptive analgesia combined with intravenous propofol anesthesia in induced abortion.

Methods: Totally 175 women (ASA class I) undergoing induced abortion were randomized into 5 groups. In K10, K5, and K1 groups, the patients were given 50 mg flurbiprofen 10, 5 and 1 min before the operation, respectively, and in F group, 1 microg/kg of fentanyl was administered 10 min before the operation.

[Comparison of levobupivacaine, ropivacaine and racemic bupivacaine in patient-controlled epidural analgesia after cesarean section].

Objective: To compare efficacy and side effects of patient-controlled epidural analgesia (PCEA) with levobupivacaine, ropivacaine and racemic bupivacaine after cesarean section.

Methods: In this prospective, randomized double-blind study, 90 ASA I-II full-term nulliparous women (aged 25-38 years with body weight of 59-87 kg) undergoing elective cesarean section under spinal-epidural anesthesia equally allocated into 3 groups. PCEA was administered with 0.

[Effects of hydroxyethyl-starch on hemorheology in patients with chronic liver disease].

Objective: To investigate the effects of hemodilution with hydroxyethyl-starch (HES) on hemorheology in patients with chronic liver diseases in vitro.

Methods: Twenty-one healthy volunteers were selected as the control group and 21 patients with chronic liver disease as the study group. Both of the two groups were divided into HSE (n=11) and Ringer's solution (n=10) groups.
