[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. RESULTS: In GE group, the blood viscosity, plasma viscosity and RBC aggregation decreased significantly at T(1) (P<0.05), but no significant variations were detected at the other time points. In G group, blood viscosity and plasma viscosity increased significantly from T(2) to T(5), and were significantly higher than those of GE group. The incidence of deep venous thrombosis of GE group (2%) was significantly lower than that of the G group (8%). CONCLUSION: The blood viscosity, plasma viscosity and RBC aggregation increase during gynecological laparoscopy, and can be reduced by epidural anesthesia and PCEA to lower the incidence of deep venous thrombosis.

[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 7.5 microg, respectively. When the patients complained of discomforts, showed bodily movements, had heart rate over 100 beats/min, or showed blood pressure increment by 20%, additional doses of propofol were given. The onset time of sensory block, time to Bromage scale 3 motor block, time to the highest sensory block level, time of operation and recovery from anesthesia, and the total dosages of propofol were recorded along with the sedative score and the side effects. RESULTS: The 4 groups were comparable for age, body weight, height and operation time (range 60-65 min) (P>0.05). Both the onset time of sensory block and the time of Bromage scale 3 motor block in groups C and D were significantly shorter than those in groups A and B (P<0.05). The time of the highest sensory block in group D was shorter than that in group A (P<0.05). Compared to the group A, the dose of propofol was reduced in groups B, C, and D by 7.1%, 28.1%, and 34.8%, respectively; propofol doses in groups C and D were significantly lower than those in groups A and B (P<0.05). Pruritus associated with the spinal anesthesia occurred in 4 (26.7%), 3 (20%), and 6 (40%) cases in groups B, C and D, respectively. CONCLUSIONS: Intrathecal sufentanil dose-dependently affect the effect of bupivacaine spinal anesthesia, and larger sufentanil dose produces better effects but more side effects. According to our results, 5.0 microg is the optimal dose for sufentanil.

[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. All the 4 groups had intravenous induction with 2 mg/kg propofo1. The patients in P group received propofol at 2 mg/kg as the control group. The heart rate (HR), mean arterial pressure (MAP) and SpO2 were monitored during the operation, and the induction time, recovery time, propofol dosage and adverse effect were recorded. The anesthetic effect of the protocols was assessed according to the visual analogue scale (VAS) and the overall patient satisfaction. RESULTS: HR, MAP, propofol consumption and the incidences of adverse effects during the operation were significantly higher in P group than in the other groups. F group had the highest incidence of respiratory depression among the 5 groups. The VAS in K10 group was significantly lower than that in K5 and K1 groups (P<0.05), but similar to that in F group (P>0.05). The overall patients' satisfaction was significantly higher than that in the other 4 groups. CONCLUSION: Flurbiprofen preemptive analgesia combined with intravenous propofol is safe and effective for anesthesia during induced abortion.

[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 0.125% levobupivacaine and 20 microg/ml morphine (group L, n=30), 0.125% ropivacaine and 20 microg/ml morphine (group R, n=30), and 0.125% bupivacaine and 20 microg/ml morphine (group B, n=30), respectively. The Visual Analog Scale (VAS) score, satisfaction rate, patients' overall impression of treatment, modified Bromage motor score, and incidence of side effects were recorded at regular intervals after operation. RESULTS: The three groups were comparable with respect to the efficacy of analgesia, patients' overall impression of treatment, motor blockade and side effects. There was significant difference in patients' satisfaction rate between group R (70%) and the other two groups (93.3% in group L and 96.6% in group B, P<0.05). CONCLUSION: PCEA with 0.125% levobupivacaine and morphine 20 microg/ml produces better analgesic effect with little side effects after cesarean section.
