BACKGROUND: The purpose of this study was to compare the effects of ondansetron and granisetron on the prevention of postoperative nausea and vomiting (PONV) in gynecologic patients. METHODS: In a randomized placebo-controlled study, 200 gynecologic patients were divided into 5 groups. Each patient received one of 5 medications: placebo (saline 3 ml), ondansetron 4 mg (O4), ondansetron 8 mg (O8), granisetron 1.5 mg (G1.5) and granisetron 3 mg (G3). They were administered intravenously immediately before the induction of anesthesia. A standardized inhalation anesthesia and a postoperative intravenous patient-controlled analgesia were applied. Twenty four hours after anesthesia, the incidence and severity of PONV and other adverse effects were assessed. RESULTS: The incidence of PONV was 88%, 83%, 75%, 70% and 60% in the placebo, O4, O8, G1.5 and G3 groups, respectively, which showed significantly lower value in the G3 group than in the placebo and O4 groups (P< 0.05). The severity of PONV was also significantly lower in the G3 group than in the placebo group (P < 0.05). CONCLUSIONS: In this study, granisetron 3 mg showed a better prophylactic effect in the mitigation of PONV in gynecologic patients then a placebo or ondansetron 4 mg.

BACKGROUND: Procaine binds to DNA and reduces cisplatin nephrotoxicity, but the mechanism is poorly understood. We explored whether procaine amelioration of cisplatin nephrotoxicity was related to down-and/or up-regulation of inflammatory response gene tumor necrosis factor-alpha (TNF-alpha), oxidative stress indicator gene heme oxygenase-1 (HO-1) or cell cycle inhibitor gene p21. METHODS: Cisplatin and procaine were intraperitoneally injected to mice at a single dosage of 16 and 80 mg/kg, respectively. Renal evaluation was performed 72 hours after cisplatin administration. The expression of transcripts and proteins was analyzed using real time RT-PCR and Western blot, respectively. RESULTS: Procaine treatment moderately attenuated necrotic changes of renal proximal tubules and increases in BUN and creatinine concentration by cisplatin administration. Kidney platinum level between the cisplatin (cis) group and the cisplatin + procaine (CisPro) group was not different. Although the level of TNF-alpha mRNA increased 4-fold higher in the Cis group than in the control, this increase was not attenuated by procaine treatment. Gene expression of p21 and HO-1 was elevated 175 and 4-times higher in the Cis group than in the control, respectively. But their expression was no further elevated, rather significantly reduced in the CisPro group compared to the Cis group. Protein abundance of p21 and HO-1 was paralleled by their respective mRNA expression. CONCLUSIONS: Procaine amelioration of cisplatin nephrotoxicity is likely to be achieved through processes other than the regulation of TNF-alpha, HO-1 or p21 gene expression.

BACKGROUND: Almost all of the blood loss occurring postoperatively in total knee arthroplasty (TKA) is due to the use of an intraoperative tourniquet in all cases. So we tried having blood transfusions done, not by anesthesiologists intraoperatively but by orthopedic surgeons postoperatively. The purpose of this study is to analyze postoperative blood loss and transfusion practice in TKAs. METHODS: We analyzed retrospectively the medical records of 64 TKAs in 40 patients between March, 1997 and February, 1999. RESULTS: Six male and fifty-eight female patients were enrolled. Their mean preoperative, immediate postoperative, and post-transfusion hematocrit were 37.1+/- 3.4, 34.4+/- 3.3, and 34.4+/-3.9, respectively. The preoperative and post-transfusion hematocrit were measured in all cases, but immediate postoperative hematocrit was measured in only 21 cases, and the hematocrit of 17 among the 21 cases was over 32 percent. Drainage amount, for the 1st postoperative day were 843 328 ml, and the total drainage amount was 993+/-362 ml. The blood transfusion amount was 2.6+/-0.9 units. There were no statistically significant differences in preoperative hematocrit, immediate postoperative hematocrit, postoperative drainage amount and postoperative transfusion amount between the general and regional anesthetic group; Preoperative hematocrit did not statistically affect the postoperative transfusion amount, but the postoperative drainage amount was statistically associated with an increased postoperative transfusion amount. CONCLUSIONS: Based on these results, it was concluded that postoperative blood transfusion in TKA was to be done on the basis of clinical impressions of orthopedic surgeons in which postoperative drainage amount was the most important consideration. Therefore, postoperative transfusion should be based on appropriate transfusion guidelines and a careful clinical examination of the patient.

Castleman's disease or angiofollicular lymph node hyperplasia is a rare lymphoproliferative disorder. Complete surgical resection was recommended in unicentric Castleman's disease. Radiotherapy was considered alternative therapeutic option. However, there have been consistent favorable responses to radiotherapy. We also experienced two cases of uncentric Castleman's disease salvaged successfully with radiotherapy. This paper described these cases and reviewed the literature about Castleman's disease treated with radiotherapy. Reviewed cases showed that radiotherapy is a successful treatment option in unicentric Castleman's disease. Furthermore, our report confirms the radiotherapy role in uncentric Castleman's disease.

PURPOSE: Intratracheal pulmonary ventilation (ITPV) is developed to decrease dead space ventilation. A reverse thrust catheter (RTC) is introduced into an endotracheal tube through an adapter. Bias gas through the RTC exits from the catheter tip. The flow of gas is redirected outward away from the lung. Gas is intermittently introduced into the lung as tidal volume (VT) by an expiratory valve. ITPV can be combined with pressure control mode, resulting in hybrid ventilation (HV). We hypothesized that HV might decrease VT, compared with volume controlled ventilation (VCV) or pressure controlled ventilation (PCV) alone. METHODS: HV was compared with VCV and PCV in 7 tracheostomized rabbits. We aimed at maintaining PaCO2 levels normal as the respiratory rates (RR) were set at 20, 40, 80, and 120/min. Blood pressure and airway pressures were monitored and dead space ratio was calculated. RESULTS: The dead spaces (VD) of VCV are 30+/-4 mL, 18+/-4 mL, 14+/-4 mL, and 12+/-5 mL and the VD of PCV are 24+/-6 mL, 16+/-3 mL, 15+/-4 mL and 12+/-4 mL at the respiratory rates of 20/min, 40/min, 80/min, and 120/min, respectively. The VD of HV are 13+/-6 mL, 9+/-3 mL, 7+/-2 mL, and 5+/-1 mL, respectively. The VT and PIP of HV are significantly lower than those of VCV and PCV at the same RR. CONCLUSION: It can be concluded that HV can be applied to minimize the airway pressures and dead space ventilation of VCV and PCV.

In cervical spine disease patients, the authors performed awake intubation with a flexible fiberscope under local anesthetic preparation to avoid insult to the cervical spine during intubation, and had patients self pronate for positioning to prevent possible complications durings the turning from cart to operating table. We performed this method in 25patients(age15-68 years,19male female6). For oral anesthesia we used 15-20cc of 4% lidocaine in a divided dose. We injected 2 cc of 2% lidocaine for each superior laryngeal nerve block and injected 4-6 cc of 2 to 4% lidocaine through the cricothyroid membrane for transtracheal nerve block with a 22-gauge intravenous catheter. It took 5-10 minutes in 23 patients and over 10 minutes in 2 patients for local anesthetic preparation. It took less than 1 minute in 15 patients, 1-4 minutes in 6 patients and more than 4 minutes in 4 patients for fiberoptic awake intubation. We observed vocal cord movement in 6 patients and blood clot in the trachea in 7 patients. Seventeen patients did pronate without help, 5 patients needed some help and 3 patients needed full support. Among the 3 patients who needed full support, 2 patients were in a halo traction state and one was in deep sedation. Ten patients complained of pain or discomfort during intubation. This complaint may be related which the time taken for intubation and inadequate local anesthesia. There were no complications related to positioning. We concluded that fiberoptic awake intubation and self pronation for positioning is a safe and useful method for anesthetic mnagement in cervical spine disease patients.

Endometriosis affects up to 5 million women in the united states. The number of cases observed at any time is 1 in 15(7%) women in the reproductive age range. Infertility occurs in as many as 30% to 40% of cases. Anatomical compromise with failure of oocyte capture and transport is an eviednt explanation for infertility in women suffering from advanced(stageIII/IV) endometriosis. In contrast, the pathophysiology in couples suffening from mild to moderate endometriosis as a sole infertility diagnosis is poorly understood. Research over the last decade indicates that women with endometriosis suffer from excessive activstion of immunocompetent cells within the pelvis. In experimental paradigms, adversd effects of a peritoneal fluid on the reproductive process of the endometriosis patients can be demonstrated and include:(1) Phagocytosis of sperm(2) Decreased sperm motility(3) Alteration of sperm-egg interactions(4) Failure of oocytes capture by the fimbria and(5) Impeded embryo development. These data raise the possibility that the intraperitoneal inflammatory process observed in women with endometriosis may be responsible for the associated infertility. The purpose of this study was to evaluate the effect of peritoneal fluid(PF) from patient with moderate endometriosis on mouse embryo development.PF was aspirated from the posterior cul-de-sac at laparoscopy and centrifuged, and the cell-free superantant was not heat-inactivated and not filtered. Fifty percent PF in human tubular fluid(HTF) media was prepared as a study group. The control group consisted of PF with a nonendometriosis and of 0.5% bovine serum albumin and HTF. The in vitro fertilization was performed with these culture media. We were observed distribution of embryo under the microscopy at 24 hours, 72 hours, 92 hours and 120 hours after insemination. The 2-cell embryonic stages in the study group(254 ovums) and those in the control group(247 ovums) at 24 hours were 50.4%, 70.4%, respectively. At 72 hours, the embryonic stages of both groups were reached the morula stage. At 72 hours, only 7.0% of the embryos in the study group reached the hatching, versus 55.7% in the control group. (p < 0.001). At the 120 hours, 100% of embryos in study group were degenerating, versus only 13.2% in the control group. As a result, the peritoneal fluid of the endometriosis patients exert an adverse influence on early reproductive performance, especially inhibiting embryo development. The peritoneal fluid may be as a mediator in the pathogenesis of endometriosis associated subfertility.
