JOURNAL FREE ACCESSEEG monitors, including BIS monitors, are becoming more widely used in clinical practice as well as in research. However, they do not seem to be adequately used, because of the lack of proper knowledge about EEGs during anesthesia. EEGs during anesthesia are influenced by noxious stimuli and their prevention, as well as the concentration of the anesthetic. Changes in EEG induced by noxious stimuli are not so simple as to shift the concentration-effect curve of the anesthetic to the left. Without adequate analgesia, BIS values or other EEG derivatives do not correctly indicate the effect of the anesthetic on the brain. Furthermore, EEG derivatives, including BIS values, have several limitations. If they do not adequately correspond with clinical status, to more clearly characterize the patient's status, it is necessary to check the raw EEG waveforms.View full abstractDownload PDF (785K)

JOURNAL FREE ACCESSWe investigated the rate of unintentional venous puncture by epidural catheters for 811 pregnant women, ASA grade I or II, scheduled to undergo combined spinal-epidural anesthesia for elective cesarean section. Patients were assigned to two groups using the TERMOTM epidural kit (404 patients, T group) or the ArrowTM epidural kit (407 patients, A group). Unintentional venous puncture was defined as when blood was aspirated from the epidural catheter. In the T group, unintentional venous puncture occurred in 22 of 404 (5.4%) epidural catheter insertions, but no blood aspiration was observed in the A group. The incidence of venous puncture was significantly higher (p<0.01) in the T group. The use of a soft spiral epidural catheter (A group) could considerably decrease the frequency of unintentional venous puncture even for cesarean section.View full abstractDownload PDF (242K)

Anesthesia Management for a Patient with Stiff-Person Syndrome Combined with Thymoma : A Case ReportJyunichiro KIBAYASHI, Jitsu KATO, Kenichi IWASAKI, Hisashi ISHIKAWA, J ...Article type: Others

JOURNAL FREE ACCESSWe experienced a patient with stiff-person syndrome who underwent thymomectomy under general anaesthesia combined with epidural anaesthesia. During the perioperative period two interesting findings were discovered. First, the tracheal tube could not be extubated because of the absence of a firm grasp just after surgery even when he regained consciousness with the presence of the fourth twiches of the train of four examined with an electrical nerve stimulator. Second, heart rate variability spectral analysis revealed dominant sympathetic nerve activity compared with parasympathetic one.View full abstractDownload PDF (326K) -

JOURNAL FREE ACCESSA seventy-year-old male (case 1) and an eighty-year-old male (case 2) who were scheduled for transurethral resection of the prostate (TUR-P) under spinal anesthesia. They showed the results of preoperative laboratory examinations within normal-range except the prolonged activated partial thromboplastin time (aPTT). Case 1 did not show a bleeding disorder in daily practical findings, and he was diagnosed with antiphospholipid antibody syndrome upon a more detailed examination. Case 2 showed a bleeding disorder and he was diagnosed with von Willebrand disease upon a more detailed examination before the operations. In both cases, the anesthesia and the operation were uneventful. In case 2, 33 IU · kg-1 of clotting factor VIII was preoperatively intravenously administered. However, in case 1, embolism of the retinal central vein occurred 4 weeks after the operation. Abnormal prolonged aPTT values indicated both a clotting tendency and a bleeding tendency.View full abstractDownload PDF (335K) -

JOURNAL FREE ACCESSBiventricular pacing has been proposed as a therapeutic alternative for patients with medically refractory heart failure. We report a case of severe dilated cardiomyopathy who underwent biventricular pacemaker implantation under general anesthesia.
A 76-year-old man was indicated for biventricular pacing. He had had heart failure of New York Heart Association (NYHA) class III and left ventricular ejection fraction of 12%. Anesthesia was induced and maintained by total intravenous anesthesia (TIVA) using propofol and fentanyl. Vecuronium was administered for muscle relaxation. The operation was uneventfully performed without any pharmacological or mechanical cardiac support. TIVA using propofol and fentanyl may be appropriate for patients with severely impaired cardiac function who are indicated for this procedure.View full abstractDownload PDF (2102K) -

JOURNAL FREE ACCESSTo evaluate the analgesic effect of continuous epidural block with 0.2% ropivacaine, we performed epidural catheterization on 10 painful non-surgical patients. After the catheter injection site was tested with an initial bolus injection of 5∼10ml of 0.75% ropivacaine or 1% mepivacaine, infusion of 0.2% ropivacaine was started at a rate of 2∼5ml · h-1. A highly analgesic effect was achieved in all cases. The mean length of hospital stay was 15±7.5 days. No major side effects were noted in any cases, but urinary retention and motor block of the lower extremity occurred in four of the five patients blocked at the lumbo-sacral area. Continuous epidural infusion of 0.2% ropivacaine was useful for pain control in non-surgical patients, but we need to be attentive to motor block and/or urinary disturbance.View full abstractDownload PDF (326K)
