30 patients were randomly divided into three groups : halothane in oxygen(N=10) ; enflurane in oxygen(N= 10) ; Thalamonal plus nitrous oxide in oxygen(N= 10). Standardized bleeding time was measured using Ivy method before and at leaat 40 min after the induction of anesthesia. Arterial pressure was maintained at+/- 200 of control values and tem-perature was kept at 35~37 degrees C. The bleeding time was prolonged by 58% in the halothane group (P<0.001). There was essentially no change in bleeding time in the groups receiving enflurane and nitrous oxide-Thalamonal group, although there was considerable variability within each group, which did not seem to be related to differences in sex, age, type of surgery, concentration of agent used or surgical procedure. In conclusion, our resultg suggest that halothane may be contraindicated in situations where optimal hemostasis is critical.

Intravenous leiomyomatosis is a rare disease entity of benign smooth muscle invading into the lumen of veins. We describe a case of intravenous leiomyomatosis originating from the uterus, growing in the inferior vena cava, and extending into the right ventricle association with multiple pulmonary metastasis. A 53-year-old woman with chest discomfort and several times attacks of syncope was treated at our hospital. The tumor was successfully removed with moderate hypothermic cardiopulmonary bypass after total hysterectomy with a bilateral salphingo-oophorectomy, and multiple pulmonary metastasis under simultaneous sternotomy and laparotomy was confirmed.

BACKGROUND: Hypertension following coronary artery bypass graft surgery (CABG) occurs frequently. Pharmacologic therapy of postoperative hypertension has often been treated with sodium nitroprusside (SNP). Nicardipine which is a dihydropyridine calcium-channel blocker, has little or no direct negative effects on cardiac contractility. Thus, we have compared the effects on hemodynamics between nicardipine and SNP after a CABG. METHODS: After a CABG, when systolic blood pressure (SBP) was elevated above 140 mmHg, patients were randomized to receive either nicardipine (N-group, n = 26) or SNP (S-group, n = 21) at an initial rate of 2ng/kg/min until the SBP was lowered to 120 130 mmHg (target blood pressure, TBP) for 10 minutes. If the TBP was not achieved, the infusion rates of both drugs were increased by 1ng/kg/min every 10 minutes. If SBP was lowered below 100 mmHg, phenylephrine was infused. Hemodynamic measurements were obtained just before (T1) and at 10 min (T2), 60 min (T3) and 24 h (T4) after the infusin of nicardipine or SNP. Infusion time, total doses, creatine phosphokinase (CK)-MB, plasma catecholamine and the use of phenylephrine were compared between groups. RESULTS: The SBP and systemic vascular resistance were significantly decreased in both groups. The cardiac index and stroke volume index were significantly increased at T3 in both groups but they were significantly increased only in the N-group at T2. The infusion time and the total doses of both drugs were significantly less in the N-group than the S-group. There were no significant differences in CK-MB, plasma catecholamine and the use of phenylephrine between groups. CONCLUSIONS: It has been suggested that the infusion of nicardipine is as effective as the infusion of SNP for the control of postoperative hypertension and the increase of cardiac output after a CABG. However, immediately after the drug infusion, nicardipine was superior to SNP in maintaining left ventricular performance.

OBJECTIVE: Aim of this study is to evaluate the pregnancy and implantation rates in fresh-embryo transfer (ET) and frozen-thawed ET cycles in women with polycystic ovarian syndrome (PCOS). METHODS: PCOS was diagnosed by the Rotterdam criteria. In 4 cases of 72 stimulation cycles, ET was not conducted due to severe ovarian hyperstimulation syndrome (OHSS). Sixty eight cycles of fresh-ET and 40 cycles of frozen-thawed ET were included in this retrospective study. Age, gravidity, body mass index, infertility duration were compared between two groups. Number of embryos transferred, implantation rate, clinical pregnancy rate and multiple pregnancy rate were compared between two groups by using chi-square test and student's t-test. RESULTS: Number of embryos transferred showed significant difference between two groups. Fresh-ET group was 4.7 and frozen-thawed ET group was 2.8 (P<0.001). However, overall clinical outcomes with fresh-ET and frozen-thawed ET cycles were similar. Implantation rates were 8.3% vs 11.5%, clinical pregnancy rates were 27.9% vs 25.0% and multiple pregnancy rates were 36.8% vs 20.0%. CONCLUSION: Although more number of embryos were transferred in fresh-ET cycles, the clinical outcomes were similar between fresh-ET and frozen-thawed ET cycles. It may be due to decreased uterine receptivity in fresh-ET cycles. Frozen-thawed ET may be used as alternative plan for cases of severe OHSS and decreased uterine receptivity expected.

We present a case of a 19-year-old male with portal vein gas embolism resulting from accidental ingestion of 35% hydrogen peroxide. Hydrogen peroxide is a commonly used germicidal cleansing agent. When it is applied to tissues, catalase causes its rapid molecular decomposition with the release of oxygen bubbles. The patient recovered without sequelae. Hyperbaric oxygenation may be of benefit in patients with respiratory compromise or central nervous system symptoms from gas embolism in hydrogen peroxide ingestion.
