JOURNAL FREE ACCESSThe time course of propofol concentrations of the arterial and jugular venous bulb blood, and their effects on the change of jugular venous bulb blood oxygen saturation (SjO2) and somatosensory evoked potential (SEP) were examined in carotid endarterectomy (CEA) patients. Twelve patients were deviled into two groups; group I (n=6) received propofol infusion at a rate of 10mg•kg-1•h-1, and infusion rate were gradually reduced to 8, 6, 4mg•kg-1•h-1 with 10 minutes durations. Group II (n=6) received continuous propofol infusion at a rate of 5mg•kg-1•h-1 with 40 minutes durations.
The value of SjO2 and the amplitude of SEP were significantly decreased following the infusion of propofol in two groups. In group I, propofol concentrations of arterial blood did not correlate with SjO2 and SEP, however propofol concentrations of jugular venous bulb blood correlated with SjO2. In group II, there existed correlation between jugular venous concentrations and SjO2 or SEP.
It is concluded that an arterial blood propofol concentration alone may fail to predict the effects of propofol on cerebral blood flow or cerebral metabolism, and the propofol concentrations of jugular venous bulb blood are useful for concidering the cerebral effects of propofol.View full abstractDownload PDF (625K) -

JOURNAL FREE ACCESSThere are several cases of hypoxemia during one-lung ventilation. Anesthetic agents are reported to reduce hypoxic response of the lung. The aim of this study was to evaluate the effect of isoflurane and propofol on oxygenation during one lung ventilation (OLV). We studied 26 patients who had OLV procedure for elective thoracic surgery, lung cancer and esophageal cancer. In 13 patients (I group) were anesthetized with isoflurane. Another 13 patients (P group) were anesthetized with propofol. The patients in both groups received thoracic epidural anesthesia with lidocaine beside general anesthesia. A double-lumen endotrachial tube was inserted, and mechanical ventilation with 100% oxygen was performed. Arterial blood gases were recorded in a lateral position with two-lung ventilation, 15min, 30min, 60min after one lung ventilation. The mean value for PaO2 during OLV in P group after 15min (281.7±28.2mmHg) were significantly (p<0.05) higher than that in I group (197.9±21.1mmHg). This findings suggest that propofol is suitable for one-lung ventilation than isoflurane.View full abstractDownload PDF (544K) -

JOURNAL FREE ACCESSWe examined the effect of sevoflurane on the appearance of amnesia and dreaming during propofol-nitrous oxide anesthesia. Sixty patients undergoing tympanoplasty were anesthesized with propofol-nitrous oxide (PN, n=20), sevoflurane-nitrous oxide (SN, n=20) or propofolnitrous oxide-0.5 % sevoflurane at a sequence of 30 min on, 30min off (PNs, n=20). The PNs patients experienced slight decrease in dreaming compared with the PN patients during anesthesia. On the day following anesthesia, the PNs group were significantly more awake alert than the PN and SN group. These results suggest that the inhalation of sevoflurane with a low concentration during propofol-nitrous oxide anesthesia improves the quality of awakening from general anesthesia, influencing on the rate of dreaming and amnesia.View full abstractDownload PDF (762K) -

JOURNAL FREE ACCESSA 34-year-old woman with acute intermittent porphyria (AIP) was scheduled for elective cesarean section. In her past history, porphyric crisis occurred after the third operation for torsion of ovarian cyst. Surgical stress and anesthetic agents were considered as the cause of porphyric crisis. She was intubated after administration of propofol and vecuronium. General anesthesia was maintained with inhaled 60% N2O, 40% O2 and intravenous propofol and fentanyl. We selected general anesthesia with propofol for the present surgery because many clinical reports suggested that propofol was safe agent in a patient with AIP and had no apparent major adverse effects on neonate for cesarean section. Intraoperative and post partum courses were uneventful and neonatal condition was satisfactory.View full abstractDownload PDF (525K) -

JOURNAL FREE ACCESSA 78-year-old man had been diagnosed as myelodysplastic syndrome two years ago. Preoperative evaluation for removal of maxillary tumor revealed severe pancytopenia and trifascicular block on the ECG. The echocardiogram showed hypertrophic cardiomyopathy. He received two units of packed red blood cell and 15 units of concentrated platelets on the day before the operation. General anesthesia was maintained with sevoflurane and 50% nitrous oxide in oxygen under the monitoring of pulmonary artery catheter. The perioperative course was uneventful without any serious bradyarrhythmias. We conclude that it is important to keep optimal oxygen transport and hemostatic function by administration of blood products, and to prevent the myocardial ischemia by vigilant hemodynamic monitoring.View full abstractDownload PDF (382K) -

JOURNAL FREE ACCESSA 54-year-old woman was admitted for evaluation of mitral stenosis and regurgitation. A flowdirected balloon-tipped catheter was passed into the PA without difficulty. Immediately after measuring the PA wedge pressure, she suddenly showed cough and hemoptysis and developed profound systemic hypotention. PA angiogram revealed extravation of contrast medium into the right pleural space. Immediately she was taken to the operating room and emergency thoracotomy was performed. The bleeding point was easily identified in the right main PA and quickly oversewn. On the following day, active bleeding was found via the chest tube. The hemostatic surgery was performed with electrocautery. Then, severe pulmonary hypertension and hypoxemia persisted, and pulmonary edema occurred frequently with foamy bronchial secretions. It was felt that her chance for survival would be enhanced by mitral valve replacement. The surgery was undertaken on the 23th postoperative day. She recovered uneventfully and discharged from the ICU on the 30th postoperative day. We reported her perioperative management and discussed potential adverse effects of the PA catheter insertion.View full abstractDownload PDF (514K) -

JOURNAL FREE ACCESSWe present anesthetic managements of 18 cases (12 epiglottic cysts and 6 tongue base cysts) of pharyngeal and laryngeal cysts during 15 years. Epiglottic cysts frequently affected middle-aged or older males, while tongue base cysts frequently affected infants. Tracheal intubation was difficult in 6 cases (4 epiglottic cysts and 2 tongue base cysts) . In 3 cases, difficulty with tracheal intubation was recognized after induction of anesthesia. The fiberoptic bronchoscope was a useful device for tracheal intubation for such difficult cases. When oral intubation with a fiberoptic bronchoscope is difficult, nasotracheal intubation should be tried. In all adult cases with difficult intubation, cysts were located on the right side of the epiglottis or tongue base. Intubation may be difficult, when the cyst is located on the right side. In one infant with a tongue base cyst, intubation became possible after puncture and aspiration of the cyst.View full abstractDownload PDF (1180K) -

JOURNAL FREE ACCESSThe infusion rate select mode is a new function of a disposable continuous infusion pump, called the Syringector®.
This allows the operator to select three different infusion rates. These are two pumps with different flow selection. The one has an infusion rate of 1, 2, or 3ml•h-1. The other has an infusion rate of 2, 3, or 5ml•h-1. The infusion rate of 3ml•h-1 in the first one is made by integrating the two flows of 1 and 2ml•h-1 using two different rate-control ports. The infusion rate of 3ml•h-1 in the second one is made by a single rate-control port. To evaluate the efficacy of the infusion rate select mode, these two different types of the pumps were compared at the same infusion rate setting of 3ml•h-1. Although, the infusion rates of the two different types of pumps were not significantly different, the variation in the infusion rates of the pump with the infusion rates of 1, 2, or 3ml•h-1 was significantly larger than that of the pump with the infusion rates of 2, 3, or 5ml•h-1. The reason for this difference was thought to be due to increased errors related to the use of two ratecontrol ports in the first one which was larger than the margin of error in the second one.
The infusion rate select mode was found to induce a larger variation in the infusion rate than the usual infusion rate setting.View full abstractDownload PDF (526K) -
