JOURNAL FREE ACCESSA helical computed tomography (CT) has been introduced in our operating room for intraoperative CT. We examined several points of anesthetic management during intraoper-ative CT. Measurements of a scatter dose were made in a CT room. The scatter dose was 5.6μSv/lscan at 1.5m from the phantom, and maximum scatter doses were noted at scatter-ing angles between 45° and 135°. A lead gown and a protective screen reduced the radiation dose to 13.4% and 1.6%, respectively. On simulation of anesthetic management for intra-cranial surgery, a radiation screen reduced the radiation dose to 8%. Simulation of every surgical position was performed, and the arrangements of apparatus in a CT room (i.e. a surgical bed, an anesthetic apparatus, etc.) were decided. Moreover, the respiratory circuit was changed to an elastic and flexible circuit (RX Circuit, Intertec Resources Inc.).
Measurements of a scatter dose and simulation of intraoperative CT were useful for preparation of a manual, and consequently they have made it possible for us to carry out intraoperative CT rapidly, smoothly and safely.View full abstractDownload PDF (616K) -

JOURNAL FREE ACCESSThe present prospective study was designed to compare the effects of pre-vs. postoper-ative commencement of continuous epidural analgesia on postoperative pain relief and comfort. Forty one patients scheduled for upper abdominal surgery under general anesthe-sia were randomly assigned to receive epidural analgesia starting either before the skin incision (A group, n=21) or at the closure of the peritonium (B group, n=20). An epidural catheter was placed between T8 and T12 intervertebral level corresponding to each surgical field. Epidural analgesia was performed as follows: 5 to 7ml of 1% mepivacaine initially followed by infusion of a total of 96ml of solution containing bupivacaine (2.5mg•ml-1) and buprenorphine (4.2μg•ml-1)over 48 hours at 2ml•h-1 with a ballon reservoir. There were no significant differences in the postoperative vital signs, visual analogue scales both at rest and at movement, verbal pain scores, additional analgesics, conscious level, comfort, and recovery of the intestinal and motor functions. In conclusion, the present results show that the pre-operative start of epidural analgesia is not always beneficial for patients undergoing upper abdominal surgery compared with the post-operative start, questioning the efficacy of pre-emptive epidural analgesia under general anesthesia.View full abstractDownload PDF (776K) -

JOURNAL FREE ACCESSWe examined the effect of epidural morphine given during Cesarean section, in the amount of breast milk and infant weight gain in the early puerperal period. Twenty five patients undergoing Cesarean section, in which 14 were administered epidural morphine (morphine group) and the other rest were not (non-morphine group), were compared with 11 women who delivered vaginally (NSD group). All women started to feed breast milk on the first day after delivery. The ratio of the patients receiving supplemental analgesics after the operation was lower in the morphine group compared with that in the non-morphine group. The amount of breast milk in the morphine group and the non-morphine group was smaller than that in the NSD group on the second day after delivery, however there was no difference between the morphine group and non-morphine group. There was no significant difference in infant weight gain among the groups. It is suggested that epidural morphine cannot improve the decrease in breast milk formation associated with Cesarean section although it reduced postoperative pain.View full abstractDownload PDF (647K) -

JOURNAL FREE ACCESSTo investigate the effect of laparoscopic cholecystectomy (LC) on the liver function, we measured serum alcohol dehydrogenase (ADH), glutathione S-transferase (GST-α) activ-ities, and portal venous blood flow by means of a transit time ultrasonic volume flowmeter before, during and after the operation. The patients were randomly divided into two groups; a GOS group (n=9) and a GOS+diltiazem group (n=9). In both groups, anesthesia was maintained with nitrous oxide-oxygen-sevof lurane. The GOS+diltiazem group received intravenous infusion of 5∼30μg•kg-1•min-1 of diltiazem, so that blood pressure during operation decreased to 80% of pre-operation. ADH and GST-α increased signifi-cantly during CO2 insufflation in both groups. Portal venous blood flow decreased to 30.3±9.4% and 37.9±9.5% of preoperative level in each group. There was no significant differ-ence in changes in ADH, GST-α activities and portal venous blood flow between the groups. These findings suggest that LC may cause mild liver damage due to hepatic ischemia during pneumoperitoneum.View full abstractDownload PDF (771K) -

JOURNAL FREE ACCESSWe report the anesthetic course of laparoscopic ovarian cystectomy in a newborn infant. A 19-day-old infant (height, 52cm; weight, 3, 900g) was presented with appetite loss and a right ovarian cyst diagnosed with ultrasonography antenatally. The patient was born at 41 week's gestation, weighed 3, 860g at birth, and had no concurrent abnormalities. Anesthesia was maintained with sevoflurane, nitrous oxide, fentanyl and pancuronium. The patient tolerated intraabdominal pressure (IAP) of 8mm Hg well in the horizontal position. When IAP of 7mm Hg was combined with a head-down tilt of 10°, higher peak inspiratory pressure was required to maintain PaCO2 within a normal range, the arterial to end-tidal carbon dioxide gradient (a-ETDCO2) increased to 12mm Hg, and inferior vena cava pressure (IVCP) increased to 16mm Hg. The surgery was completed without complications, the patient recovered uneventfully. Presumably, the changes in a-ETDCO2 and IVCP were due to an increase in pleural pressure by the cephalad movement of the diaphragm. It is suggested that PaCO2 could be underestimated during pneumoperitoneum combined with the Trendelenburg position in newborn infants. IVCP could be a guide for safe pneumoper-itoneum and positioning in neonates, as is in repair of abdominal wall defects.View full abstractDownload PDF (582K) -

JOURNAL FREE ACCESSThree cases of postoperative parotid gland swelling, so-called anesthesia mumps, are presented. Warm and elastic enlargement of the parotid gland was recognized, which diminished in a few days without any special treatment. Although approach to patients with porotid gland swelling is to alleviate patient's symptom with regional cooling and/or non-steroidal anti-inflammatory drugs, attention must be paid to possible danger of airway compromise.View full abstractDownload PDF (443K) -

JOURNAL FREE ACCESSTransillumination of the soft tissues of the neck using a lighted-stylet (TrachlightTM) is an intubating technique which is easy to learn and its effectiveness has been reported in tracheal intubation in patients with difficult airways.
This report presents a successful intubation case with TrachlightTM in a patient whom we failed to intubate by laryngoscopic and bronchoscopic technique in the last three consecutive anesthesias.
We consider that TrachlightTM is on the effective device to intubate the tracheas of patients with a difficult airway.View full abstractDownload PDF (396K)
