BACKGROUND: Many reports on the change of pseudocholinesterase activity in pregnant women showed that it declines during pregnancy and in the immediate postpartum period. In Korea, there are two papers that show dissident results. However, they didn't prove that the subjects in their studies had genotypically normal enzyme. So, we compared the pseudocholinesterase activities between nonpregnant and term-pregnant women who have the genotypically normal enzyme. METHODS: We measured the dibucaine, fluoride, chloride number as well as the pseudocholinesterase astivity using butyrylthiocholine as substrate by automatic analyser, urea and scoline numbers using benzoylcholine as substrate by manual technique in nonpregnant(n=15) and term-pregnant(n=15) women aging 20 to 40 years old before induction of anesthesia. RESULTS: The dibucaine, fluoride, chloride, urea and scoline numbers(mean+/-SD,%) in female subjects were 86+/-1.2, 50+/-5.2, 5+/-2.4, 47+/-2.8 and 92+/-2.0, respectively. There were two subjects showing low pseudocholinesterase activity(<4.8 U/ml) and the one(3.9 U/ml) was in nonpregnant group, the other(4.5 U/ml) in term-pregnant group. We found that they had genotypically normal enzymes because their inhibition numbers were within normal ranges. Pseudocholinesterase activity(mean+/-SD) in term-pregnant group(7.04+/-1.30) was significantly decreased compared with that in nonpregnant group(9.15+/-2.01)(P<0.01). CONCLUSIONS: We conclude that in subjects with the genotypically normal enzyme, term-pregnant women had significantly lower pseudocholinesterase activity than nonpregnant ones did.

Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta whitch originates just distal to the level of the origins of the coronary arteries, and whitch includes a wide spectrum of pathologic changes. A 27 years-old-female was admitted because of further evaluation of known some heart disease. Clinical diagnosis of supravalvular aortic stenosis was made by echocardiography and angiography. We presented a case of supravalvular aortic stenosis with a review of literature.

The provocation test of variant angina are known as ergonovine test, hyperventilation, acetylcholine, exercise and cold pressor test, but beta-blocker provocation test has not been reported as a case. So, this paper reports on the diagnosis of variant angina by beta-blocker provocation test and the case of subendocardial infarcion induced by this test. This study reports with literature and investigation about the following case : A 45-year-old man with a history of recurrent episode of typical angina on the early morning for the past 20 days. He was administrated beta-blocker given by oral route, and on the next morning there was chest pain as same degree as before, Holter EKG displayed ST segment elevation and ventricular tachycardia. It was confirmed focal spasm on coronary angiography, ST segment elevation on EKG, and newly developed hypokinesia on left ventriculogram and followed-up echocardiagraphy. When the chest pain is absent, EGK was normal. And we confirmed that elevation of cardiac enzyme was absent as a result of serial follow up study.

Typically, patients afflicted with syndrome X complained of stress induced angina pectoris, and their electrocardiograms show corresponding ST-segment depressions during exercise. However, angiography is unable to demonstrate significant coronary artery luminal narrowing and significant coronary artery spasm to provocation test. And left ventricular performance at rest remains remarkably unimpaired. Syndrome X is characterized by reduction of coronary vascular reserve but without depression of left ventricular performance or negative effect on survival. The reduction of coronary vascular response is supposed to be resulted from reduced coronary vasodilator reponse due to abnormal contraction of coronary prearteriolar vessels. This case is a 43-year-old female who has had exertional chest pain since 5 months ago. The chest pain was relieved by rest and subligual nitroglycerin administration. The exercise electrocardiography showed significant ST segment depressions on lead II, III aVF and V4-V6 at stage 1, when she experienced chest pain. On 24 hour ambulatory electrocardiogram, significant ST segment depression was recorded at the time when the patient had chest pain. But coronary arteriography demonstrated normal coronary artery and no significant coronary artery spasm to provocation test with ergonovine maleate. On exercise thallium-201 scintigraphy, perfusion decrease was suspected on anterolateral wall of left ventricle. The patient was diagnosed as a syndrome X and was managed with isosorbide and nifedipine and her exercise tolerance increased significantly on follow up exercise test performed 1 month later. But she has complained of a few of attack of chest pain until now.

Methemoglobinemia is an uncommon but potentially fatal disorder. Most cases have no adverse clinical consequence and require no treatment, but methemoglobinemia is often overlooked as a cause of low oxygen saturation, and often mistaken for the more common causes of hypoxia by anesthesiologists despite simple bedside tests that indicate the presence of this treatable abnormality. We present a 68-year-old female patient who underwent gastrectomy for advanced gastric cancer with bleeding. In the preoperative period, the patient showed cyanosis and oxygen saturation was 85% by pulse oximeter, but oxygen saturation by arterial blood gas analysis was 100%. After tracheal intubation, the methemoglobin level was 18.3%. Ascorbic acid and methylene blue were administered. During preanesthetic evaluation, the patient had not informed the anesthesiologist that she had been taking dapsone.

BACKGROUND: Liver transplantation (LT) has become the treatment of choice for advanced liver disease. However, renal dysfunction often complicates the course of liver transplant recipients. The preoperative serum creatinine level have been shown to be an important predictor of a short-term graft and patient survival rates and the need for perioperative dialysis. This study examined the impact of the pretransplant renal function on the anesthetic characteristics and renal function after LT. METHODS: Patients undergoing LT were divided two groups according to the creatinine (Cr) level at time of LT. The following information was collected for each patient: age, etiology, weight and height, serum Cr, Cr clearance, patient survival, and cause of death. The laboratory data was collected at preoperative day, operation day and postoperative 1, 7, 30 days and 6 months. The hemodynamic profile was collected during LT. RESULTS: There were 27 patients in the renal dysfunction (RD) group. Ascites, total blood transfusion and fluid administration was significantly higher in the RD group. The hemodynamic parameters were similar in both groups. The BUN and Cr levels were significantly higher in the RD group in the perioperative period. At the preoperative period, the AST, ALT, bilirubin and prothrombin time was significantly higher in the RD group. The postoperative ICU stay and mortality rate was higher in the RD group. CONCLUSIONS: A pretransplant renal dysfunction is the result of deterioration in the liver function in the preoperative period, and indicates a greater requirement of blood and fluid during surgery.

BACKGROUND: In this study, we examined diabetic patients scheduled for elective coronary artery bypass surgery to determine whether there is an association between autonomic dysfunction and intraoperative hemodynamic instability, and if perioperative autonomic function tests are effective predictors for diabetic patients at greatest risk for hemodynamic events during the intraoperative period. METHODS: We examined 52 patients, 25 without diabetes (nonDM group) and 27 with diabetes (DM group). Preoperative autonomic function tests included are the valslava maneuver (valsalva ratio, valsalva index, strain response), change in heart rate with deep breathing (I/E ratio), change in heart rate (30:15 ratio, stress response) and diastolic blood pressure (L-S(d)) while standing. Anesthesia was established with midazolam, fentanyl, isoflurane and vecuronium. Several hemodynamic variables such as heart rate (HR), mean arerial pressure (MAP), central venous pressure (CVP), mean pulmonary artery pressure (MPAP), pulmonary capillary wedge pressure (PCWP), systemic vascular resistance index (SVRI), pulmonary vascular resistance index (PVRI), cardiac output (CO), and cardiac index (CI) were obtained at the following times: before induction; after induction; after intubation; after skin incision and after sternotomy. RESULTS: The DM group had a significantly diminished response compared with the nonDM group in the valsalva ratio, valsalva index, 30:15 ratio, and L-S(d). The remaining tests (I/E ratio, strain response, stress response) showed similar but nonsignificant diminished trend response in the DM group. Most patients had one or more abnormal test results in this group (76%), whereas in the control group most patients did not show any abnormal test results (74.1%). The comparison of hemodynamic response between the DM group and non-DM group reveal a significant difference between times within each group but not between groups. CONCLUSIONS: This study indicates that increased hemodynamic instability during the intraoperative period is not an obligatory association with diabetes and autonomic dysfunction and is not detected bypreoperative autonomic function tests in patients with coronary artery disease and diabetes mellitus when anesthesia is induced and maintained with a large dose of opioid and anesthetic agent which has minimal hemodynamic effects.

Preoperative uterine artery embolization and cervical evacuation as conservative management of cervical pregnancy has been tried in recent years. However, cervical suturing, vasoconstrictor injection, or cervical ballooning was frequently used as an ancillary measures in those procedures in most of the previous studies. We report two cases of cervical pregnancy that were successfully treated with preoperative uterine artery embolization and removal of gestational material without ancillary procedures. Our therapeutic modality seems to be safe and effective for conservative management of cervical pregnancy.

BACKGROUND: When performing spinal anesthesia, glucose is frequently added to control the extent of the anesthesia by increasing the specific gravity of the local anesthetic solution. It is not clearly known whether the added glucose directly affects the nerve blockade or not. The purpose of this study is to examine the effect of glucose solution on isolated nerve fibers in vitro. METHODS: Compound action potentials (CAPs) of A-fiber range were recorded from isolated nerves of adult Sprague-Dawley rats (300 400 gm). Tonic (0.5 Hz) and phasic (30 Hz) supramaximal stimuli were repeatedly applied to one end of the nerves and the recordings were made on the other end. Nerves were perfused with modified Krebs solution for 45 minutes initially to get baseline data and then perfused with test solutions containing different concentrations of glucose (2.5%, 5%, 7.5%) for 30 minutes. The same experiments were repeated with mannitol at the same osmolality as the glucose. RESULTS: Glucose produced a decrease in the amplitude of CAPs in a dose-dependent manner (79.2 +/- 3.4, 50.3 +/- 3.7, 34.6 +/- 4.0 for 2.5%, 5%, 7.5% glucose solutions, respectively). At each of the same concentration levels, the degree of nerve conduction blockade did not have any significant difference within the glucose groups and mannitol groups. CONCLUSIONS: Glucose, in clinically employed concentration range, directly depressed peripheral nerve conduction in vitro, probably via osmotic effect.

The hyperprolactinemia is one of the common endocrinologic cause of impotence. If hyperprolactinemia is noted in serum of an impotence patient, the pituitary adenoma should be suspected. Recently we experienced a case of pituitary adenoma combined with impotence in 65 year old male. Herein we report this case with brief review of the literatures.
