An accurate and relatively simple method for estimating the amount of acute blood loss is essential in the hemorrhagic shock patients. Conventional physiologic parameters, blood pressure, pulse rate and CVP, could not serve for evaluation of the adequate oxygen transport in the tissue. Pulmonary artery catheter is a best tool for evaluating the cardiopulmonary function and the oxygen transport system, and mixed venous oxygen saturation(SvO2) monitoring have made a great advances for early detection of cardiovascular dysfunction and the changes in peripheral tissue oxygenation. But pulmonary artery catheterization is complicated procedure in emergency setting. Although the central venous oxygen saturation(ScvO2) cannot completely replace the SvO2 value, it has a close relation with SvO2 change in variable clinical situations. We testify the usefulness of ScvO2 monitoring in 24 patients of the hemorrhagic shock. Initial resuscitation was performed with ATLS standard and continuous ScvO2 was monitored. Systolic blood pressure and pulse rate were recorded for one hour from initial resuscitation in each 15 minutes. Nineteen patient was traumatic hemorrhagic shock and five was non traumatic. Twelve of 19 patients was blunt trauma, and remains were stab in injury mechanism. Mortality rate was 29.2%. Initial ScvO2 of nonsurvivor was 43.6%, and 51.3% in survivor groups(p>0.05). In the group of stab wound and non-traumatic hemorrhage, the ScvO2 was gradually increase by time. But ScvO2 in survivors of blunt trauma was increased first 30 minutes and decrease afterthen. Continuous monitoring of ScvO2 may by partly useful in resuscitation for hemorrhagic shock. It is more valuable in the blunt trauma than in the penetrating injury or non-traumatic hemorrhage.

STUDY DESIGN: A case report. OBJECTIVES: Lumbar burst fracture was treated with operation, which delayed recollapse of L1 and led to conus medullaris syndrome. SUMMARY OF LITERATURE REVIEW: After operation, conus medullaris syndrome causing by delayed recollapse is not frequently reported. MATERIALS AND METHODS: A 56-year-old male was admitted with lower back pain caused by a fall. Radiologic findings showed L1 burst fracture with about 42% of height loss. There was no neurologic deficit. Posterior fusion was performed using instrumentation. Five weeks after the operation, the patient was admitted for urination and defecation difficulty. Radiologic findings showed that the L1 had recollapsed with about 38% of height loss. To resolve the problem, anterior surgery was performed. RESULTS: Two years after surgery, bladder and anal sphincter dysfunction wasn't recovered. CONCLUSIONS: Lumbar burst fracture should be follow up carefully until union of the fracture because burst fracture leads to delayed recollapse.

We experienced a case of clipping of an intracranial aneurysm of a 63 year old male with a subarachnoid hemorrhage under general anesthesia. Preoperative electrocardiography showed complete Left Bundle Block (LBBB) without subjective symptoms. Among the intraventricular blocks, bundle branch block is the most common type and in particular, complete LBBB may progress to the more serious condition of complete heart block. Consideration of anesthetic management in such patients requires a knowledge of normal cardiac physiology, neurophysiology, the circulatory effects of various anesthetic agents and the pathophysiology of these diseases, to prevent any hypertension in response to intubation and surgery. We report upon the anesthetic management of a patient for clipping of an intracranial aneurysm with complete LBBB, which was performed successfully without complication.

BACKGROUND:Outpatient surgery has recently grown in popularity. This trend has affected the practice of anesthesia and has also led to an increasing interest in the development and use of short-acting anesthetic and analgesic agents. METHODS: One hundred fifty patients scheduled for outpatient surgery were randomly allocated to receive propofol, sevoflurane or isoflurane anesthesia with tracheal intubation. Clinical recovery times were analyzed as emergence, recovery, cognition and discharge. All adverse events were noted. RESULTS: Sevoflurane resulted in significantly shorter times to emergence (2.9 min), recovery (4 min), cognition (5.5 min) and discharge (13.4 min) than isoflurane. Propofol resulted in shorter times to emergence (2 min), recovery (2 min), cognition (3 min) and discharge (6.6 min) than isoflurane, but these were not significant. Also, sevoflurane resulted in shorter times to emergence, recovery, cognition and discharge than propofol, but not significantly. Among the adverse events noted, the percentages of postoperative nausea and vomiting (PONV) after anesthesia were 8%, 20% and 24% for the those who received propofol, sevoflurane and isoflurane, respectively. Propofol resulted in a significantly lower incidence of PONV than sevoflurane or isoflurane. There was no significant difference between sevoflurane and isoflurane in this respect. CONCLUSIONS: Sevoflurane and propofol are better anesthetics than isoflurane for outpatient anesthesia because of their rapid recovery times and a lower incidence of postoperative nausea and vomiting.

The vagina is an infrequent site of primary sarcomas, which are less than 2% of all malignant vaginal neoplasm. The most common malignant mesenchymal tumor of the vagina is rhabdomyosarcoma, but leiomyosarcoma is rare type tumor of the vagina. Microscopically, spinle cells with pleomorphic nuclei and mitotic figures were frequently noted, but cross-striations were not found in the tissue. Alpha-smooth muscle actin and desmin were positive, but sarcomeric actin was negative in the tumor cells. The authors report a case of primary leiomyosarcoma of the vagina with brief literature review.

BACKGROUND: This study was designed to compare the antiemetic effects of propofol, ondansetron, droperidol and metoclopramide for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing middle ear surgery. METHODS: One-hundred-twenty patients were scheduled for middle ear surgery (tympanomastoidectomy and tympanoplasty). Patients received propofol (0.5 mg/kg), ondansetron (60microgram/kg), droperidol (20microgram/kg) or metoclopramide (0.2 mg/kg) intravenously at the end of the surgical procedure. The assesment of PONV was performed during 3 periods after receiving anesthesia; 0 to 2 hours in the postanesthetic care unit, 2 to 12 hours and 12 to 24 hours in the ward. RESULTS: The percentage of no emesis during the 0 to 2 hour period after receiving anesthesia was 93% for the those who received propofol, 73% for the those who received ondansetron, 70% for the those who received droperidol, and 70% for the those who received metoclopramide. The respective corresponding incidence during the 2 to 12 hour period after receiving anesthesia was 86%, 66%, 63%, and 63%, and the respective corresponding incidence during the 12-24 hour period after receiving anesthesia was 90%, 66%, 66%, and 66%. No clinically adverse events were observed in any of the groups. CONCLUSIONS: A small dose of propofol is a better antiemetic than ondansetron, droperidol or metoclopramide for prevention of postoperative nausea and vomiting after middle ear surgery.

Porokeratosis is a genodermatosis that is characterized by abnormal epidermal keratinization with the histologic finding of a cornoid lamella. Linear porokeratosis is an uncommon variant that presents a characteristic linear nevoid distribution along the Blaschko's lines and linear porokeratosis has the highest potential for malignant degeneration of all the porokeratoses. Many treatment modalities have been used, but the treatment outcomes are variable and the treatments are poorly standardized. We report here on a case of linear porokeratosis in a 48-year-old female who showed localized, linear, brownish macules with a well-demarcated hyperkeratotic border on the left lower abdomen and back.

BACKGROUND/AIMS: Hypoxemia is often associated with liver cirrhosis without cardiopulmonary diseases. Pulmonary vascular impairments including intrapulmonary shunt have been considered as a major mechanism of hypoxemia. The aim of this study was to determine the incidence and pathophysiologic basis of hypoxemia in cirrhotic patients without respiratory symptoms. METHODS: In fourty three cirrhotic patients without heart and lung diseases, we performed the arterial blood gas analysis and calculated alveolar arterial oxygen gradient (A-aO2). According to the A-aO2, the patients were divided into hypoxemic and normoxemic groups. In each group, a Tc-99m-macroaggregated albumin (Tc-99m-MAA) scan, a contrast-enhanced echocardiography and a pulmonary function test were performed. RESULTS: Twenty-eight of 43 patients (65%) showed hypoxemia. Hypoxemic patients showed significantly more increased shunt fraction of 3.1 1.4% than normoxemic one of 2.1 1.1% in the Tc-99m-MAA scan (p<0.05). However, only two of hypoxemic patients had shunt fraction above physiologic shunt range. By contrast-enhanced echocardiography, an intrapulmonary shunt was confirmed in one patient. There was no significant correlation between the shunt fraction and the hepatic reserve based on the Child-Pugh classification in hypoxemic patients. In the results of pulmonary function test, only DLco decreased more significantly in hypoxemic group than in normoxemic group (58.4 14.2 % vs 75.3 16.5% of predicted, p<0.05). CONCLUSIONS: Hypoxemia is not infrequently observed in cirrhosis, but incidence of significant intrapulmonary shunt is low. Therefore, other mechanism such as diffusion defect may be suggested to play a role in the development of hypoxemia in cirrhotic patients without respiratory symptoms.

BACKGROUND AND PURPOSE: Arginine esterase(Ancrod), a thrombin-like enzyme, purified from the venoms of Agkistrodon halys, has known to cleave fibrinopeptide A from the fibrinogen and lead to circulation of soluble noncross-linked "ancrodfibrin', which stimulates endogenous T-PA release.Many authors have suggested clinical applicability of this enzyme,but clinical studies on its fibrinolytic action has been insufficient.Thus we studied the influence of this enzyme on fibrinolytic activity in cerebral infarction. METHOD: We observed the change of euglobulin fibrinolytic activity, t-PA antigen, t-PA activity, fibrinopeptide A, fibrinogen, FDP and D-dimer, during 12 hours after a bolus intravenous administration of 0.25 unit of the arginine esterase to the 9 patients with cerebral infarction. RESULT:There was no change of the euglobulin fibrinolytic activity, fibrinopeptide A and t-PA Ag but there was significant increase in both t-PA activity and FDP, D-dimer and significant decrease in fibrinogen. CONCLUSION: Our result suggest that arginine esterase converts fibrinogen to a fibrin polymer which has a increased susceptibility to lysis by plasmirl This enzyme seems to amplify T-PA activity through the consequent increase in FT)P, because there is no increase in the euglobulin fibrinolytic activity, fibr'mopeptide A and t-PA Ag suggesting direct T-PA release. Arginine esterase, having action of effective defibrinogenation and safe fibrinolysis,could be used for the thrombus related disease.
