JOURNAL FREE ACCESSIt has been shown that inhalation of pure oxygen causes a significantly greater degree of absorption atelectasis than that of a lower concentration of oxygen. We examined 21 patients scheduled for gastrectomy to determine whether this is due to the working mecha-nism of the postoperative impairment of oxygenation and/or the development of atelectasis. The patients inhaled either pure oxygen or 40% oxygen during induction and emergence periods. There were no differences in PaO2 and the incidence of atelectasis by chest X-Ps between the two groups in 24 hours postoperatively. We conclude that the difference in inhaled oxygen concentrations during induction and emergence periods does not affect the incidence of the postoperative oxygenation impairment and atelectasis.View full abstractDownload PDF (403K) -

JOURNAL FREE ACCESSWe evaluated changes in intra-ocular pressure (IOP) and cerebral hemoglobin oxygen saturation (rSO2) during laparoscopic surgery in the Trendelenburg position(n=16) Continuous lumbar epidural block with 1.5% mepivacain was performed on all patients. These patients were allocated randomly to two groups: continuous propofol infusion group (group Epi+Propofol) and isoflurane, oxygen and nitrous-oxide group (group Epi+GOT). In group Epi+GOI, the IOP elevated significantly 30min after the intra-abdominal CO2 insufflation and Trendelenburg positioning. However, in group Epi+Propofol, the IOP did not show any change throughout the study, and was significantly lower than that in group Epi+GOI. The rSO2 in both groups did not change throughout the study, and no significant differences were observed between two groups. Therefore, propofol did not increase IOP during laparoscopic surgery in the Trendelenburg position.View full abstractDownload PDF (601K) -

JOURNAL FREE ACCESSTen patients with WPW syndrome underwent surgical operation using total intravenous anesthesia (TIVA). Propofol, fentanyl and ketamine combination (PFK) and droperidol, fentanyl and ketamine combination (DFK) were used for TIVA. No significant ECG changes due to TIVA were seen during anesthesia. TIVA seems to be safe for WPW syndrome patients. We gave a report of a patient who showed paroxysmal supraventricular tachycardia during CVP monitoring.View full abstractDownload PDF (608K) -

JOURNAL FREE ACCESSHeat and Moisture Exchanger Filters (HMEF) are used increasingly to prevent the contamination of anesthetic apparatuses and to limit cross-infection.
In order to investigate MRSA removal efficiency of the HMEF (DAR HYGROBAC "S"), experiments were performed in vivo. Ten intubated and mechanically ventilated patients infected with MRSA in their sputum for surgical patients were studied. The presence of a HMEF between the patient and the Y-piece prevented any detectable contamination from reaching the circuit.
Results in this study showed that there was no longer any need to sterilise anesthesia machines if HMEFs were used. HMEF use appears to offer substantial advantages as regards to cost, ease of use and patient safety. The use of HMEF has eliminated the risk of cross-contamination of patients from anesthesia equipment.View full abstractDownload PDF (360K) -

JOURNAL FREE ACCESSA patient who had shown severe anemia for more than 80 years was successfully treated without blood transfusion in spite of low hemoglobin levels (2.6g/dl). The hemodynamics and oxygen transports were evaluated following operation. Systemic oxygen delivery was 5.9∼9.3ml/kg/min, and oxygen consumption (2.2∼4.8ml/kg/min) was dependent on oxygen delivery. Nevertheless, base excess and lactate/pyruvate ratio as indices of the tissue hypoxia were maintained within the normal range. There appears to be some differences in the mechanism of the oxygen utility between chronic anemia and acute hemodilution.View full abstractDownload PDF (625K) -

JOURNAL FREE ACCESSWe report on the anesthetic management of reconstruction surgery in a patient with tracheal stenosis caused by prolonged endotracheal intubation. Prior to the start of the operation, the right axillary artery and the right femoral vein were cannulated as blood access rout for PCPS (percutaneous cardiopulmonary support) under epidural anesthesia and continuous intravenous anesthesia with propofol. Oxygenation of the blood during the operation was satisfactoriey under the patients spontaneous breathing with the support of PCPS. Propofol provided good sedation for the patient postoperatively, which was neces-sary to keep the operation site immobile.View full abstractDownload PDF (1006K) -

JOURNAL FREE ACCESSIntraoperative airway management is a key issue for an anesthesiologist. In this report, we present a 69-year-old female in whom we managed her airway using a suctioning catheter as a tracheal tube. The patient had been intubated with a 7mm tracheal tube due to the tracheal stenosis at 5cm proximal to the carina preoperatively. Intraoperatively, her trachea was cut out and we tried to intubate both bronchi separately. But the right bronchus was too strictured to be intubated with any given size of tracheal tube. Because of this, we intubated the bronchus with a 14Fr. suctioning catheter, and ventilation was performed through it. Spot was kept above 93% during the surgery.View full abstractDownload PDF (377K) -

JOURNAL FREE ACCESSA 71-year-old man was scheduled to undergo laminectomy. He had hypertension, diabetes mellitus and atrial fibrillation. Anesthesia was induced with 200μg fentanyl and 120mg propofol. Tracheal intubation was facilitated with 7 mg vecuronium. Anesthesia was maintained with 70% N2O/30% O2 and propof ol. His operation was finished uneventfully. On the 1 st postoperative day (1 POD), he complained of severe abdominal pain and his serum amylase level was elevated to 967IU/l(normal 43∼116). Abdominal CT showed minimal inflammation of the pancreas. He was put on a fast and received only intravenous fluids for 4 days. Nafamostat mesilate and ulinastatin were administered. On 6 POD, his serum amylase returned within the normal range. We should be aware of the possibility of postoperative pancreatitis after propofol administration.View full abstractDownload PDF (417K) -

JOURNAL FREE ACCESSA 51-year-old male with right cerebral infarction underwent distal gastrectomy for gastric cancer under continuous propofol infusion combined with epidural anesthesia. Five ml of 2% mepivacaine per 45 minutes was given for epidural anesthesia. The total dose of mepivacaine was 700mg. Continuous propofol infusion was discontinued at the end of surgery. Although the patient recovered well from anesthesia in the operating room, convulsion of the right upper extremity occurred immediately after admission to the ICU. Propofol might be a factor in causing the convulsion of the right arm.View full abstractDownload PDF (499K)
