BACKGROUND: The aims of this national survey were to determine the views of Korean people regarding the specialty of anesthesiology and the role of anesthesiologists and to consider the ways in which individual anesthesiologists and the Korean Society of Anesthesiologists inform the public. METHODS: This off-line national survey was conducted by a professional research organization to obtain exact and reliable data. The questionnaire included structured questions to identify perceptions of the specialty of anesthesiology and the role of anesthesiologists inside and outside the operating room, people's desire for explanation of anesthesia by anesthesiologists, and their opinion about the best way to raise awareness about anesthesia and anesthesiologists. RESULTS: Of the respondents, 25.2% did not know that anesthesiologists are in charge of anesthesia during surgery. Furthermore, even respondents who knew that had very little knowledge of anesthesiologists' actual roles inside and outside the operating room. Respondents wanted their anesthesiologist to inform them about their anesthesia. CONCLUSIONS: The public's awareness regarding the role of anesthesiologists seems to be inadequate. To improve this awareness, in hospitals, each anesthesiologist should provide patients with more exact and detailed information. Simultaneously, the National Society of Anesthesiology should provide systematic information reflecting the public's thoughts.

OBJECTIVE: Vascular endothelial growth factor(VEGF)-C is involved in lymphangiogenesis and spreading of cancer cells via lymphatic vessels. The aim of the present study is to investigate the relationship between the absence of cerebral lymphatic vessels and low metastatic rate of brain tumors. METHODS: Immunohistochemical stains were performed for VEGF-C and VEGF in surgically resected specimens from 57 patients with primary(38 cases, low grade : 10 cases, high grade : 28 cases) and metastatic(19 cases) brain tumor. RESULTS: The expression of VEGF-C was higher in metastatic carcinoma(68%) than in high-grade primary tumor(29%). There was no difference for VEGF expression between high grade brain tumor (71%) and metastatic carcinoma(58%). CONCLUSION: Low VEGF-C expression of primary brain tumors may play a role in low metastatic rate of brain tumors.

BACKGROUND: Sometimes hypoxemia occurs in the postoperative recovery room because of postoperative residual curarization (PORC). Some reports show that postoperative residual curarization is common. PORC occurs after the use of the long-acting muscle relaxants. It has been recommended to use intermediate-acting muscle relaxants and a TOF monitor to decrease PORC. The purpose of this study was to examine whether the use of the TOF monitor during propofol anesthesia affects the incidence of postoperative residual curarization. METHODS: 38 ASA I or II patients were divided randomly into two groups of 19 each. They received propofol-fentanyl-nitrous oxide for anesthesia. Pancuronium (80 100 microgram/kg) was used to facilitate tracheal intubation and additional doses were used to maintain surgical relaxation. The requirement for incremental doses of pancuronium and adequacy of recovery following reversal were assessed, either with (control group:n = 19) or without (experimental group:n = 19) TOF monitoring. Fifteen minutes after the arrival at the recovery room, neuromuscular function was assessed clinically and by using TOF. RESULTS: There were no statistical differences in body weight, age, or duration of operation between the two groups. There was no statistical difference in the total dose of pancuronium and total dose of pancuronium relative to body weight and duration of operation. There were statistical differences in TOF ratio in the recovery room (0.73 vs. 0.86). The incidence of PORC was 47% in the control group and 5% in the experimental group. CONCLUSIONS: Though the monitoring of TOF did not effect the dose of muscle relaxant, it may have reduced the incidence of PORC. However, the PORC had no clinical significance because the mean TOF ratio in the two groups was over 0.7 and there were no clinical signs of residual muscle weakness.

A 36-year-old woman (para 1-0-2-1) was transferred to Korea University Hospital at 38 weeks gestation for dyspnea and chest pain. On admission, her blood pressure ranged from 130/ 70 to 230/130 mmHg, the heart rate was 144 beats/min and respiratory rate was 36/min. The ECG pattern, serum creatinine phosphokinase and lactic dehydrogenase levels were consistent with acute myocardial infarction. The baby was delivered by cesarean section under general anesthesia with nitroglycerin and propranolol support, After delivery, the patient was diagnosed as having pheochromocytoma by hormone study, abdominal magnetic resonance imaging, and computerized tomography scan. Removal of tumor was suceessfully done under combined general and epidural anesthesia after preoperative preparation with phenoxybenzamine and propranolol for two weeks. Postanesthetic recovery was uneventful.

For the evaluation of the correlation between the ETCO2 and the PaCO2 in post-extubated spontaneously breathing patients, we tested 30 patients in recovery room with Salter Divided Nasal Cannula, which have permanent bamer in the face piece and a dual tubing set that allows end tidal sampling from one nare and oxygen delivery to the other. When the wave form of capnogram looked regular and normal, the value of ETCO2 was recorded and the arterial blood was taken from the radial artery to analize blood gas immediately. The results were as following; 1. The mean value of PaCO2 was 42.0+/-4.8 mmHg. 2. The mean value of P(ET)CO2 was 39.3+/-5.1 mmHg. 3. The value of P(ET)CO2 acquired with Salter Divided Nasal Cannula hase close positive correlation with the values of the PaCO2. (PaCO2=0.75 x P(ET)CO2+/-12.64, r=0.79, p<0.001)

Pulmonary alveolar proteinosis is characterized by the remittent or progressive accumulation of lipid-rich proteinaceous material within the alveolar sacs in the absence of inflammatory response. Whole-lung lavage is the only consistent treatment for pulmonary alveolar proteinosis. We have utilized whole-lung lavage for the successful treatment of a 62 year-old female patient with pulmonary alveolar proteinosis. There was no persistent complication during the procedure and the postanesthetic recovery except temporary fever and hypoxic event. The patient was symptomatically, physiologically, and radiologically improved within days after the procedures.

We experienced a case of postoperative quadriparesis secondary to operative position in a patient with pre-existing, asymtomatic,cervical neurilemmoma. The patient was admitted with chronic otitis media for mastoidectomy on right side. There was no specific event throughout operation and anesthesia but developed quadriparesis one hour after arrival on ward. With magnetic resonance imaging, the patient was dignosed to have cervical neurilemmoma. On seventh postoperative day the patient had second operation,cervical laminectomy and tumor removal. Ten days after second operation he was discharged without any complication. Eight months later he had mastoidectomy on the left side and was discharged without any sequale.

An one day old female baby was admitted to the Pediatric department of Korea University Anam Hospital for the evaluation of her facial anomaly. She was born by spontaneous vaginal delivery at term weighing 3.8 kg. On initial examination, she was noted to have congenital trismus and have cleft lip and palate. Bands of fibrous tissue were noted to extend from the superior alveolar part to inferior part at decidual molar tooth region and allowed oral opening of only 5 mm. She was transfered to the Plastic Surgery department under the diagnosis of cleft palate lateral synechia syndrome for resection of her synechial bands. In the operating room ECG, pulse oximeter and precordial stethoscope were applied to the patient and then, anesthesia was induced with , O2, N2O and enflurane. The 60 cm Olympus fiberscope with an external diameter of 2 mm was used and well lubricated 3.0 mm uncuffed endotracheal tube was threaded over the fiberscope through the oral cavity. The fiberscope was advanced into the midtrachea, then the endotracheal tube was passed over the fiberscope into the trachea After securing of the endotracheal tube, two lateral synechial bands were surgically divided. She tolerated oral feedings on postoperative 5 days without difficulty and discharged from the hospital on postoperative 6 days.
