A new colorimetric carbon dioxide (CO2) indicator Colibri is a disposable, compact and light weighted device. Colibri does not need to be calibrated and is easily usable in an emergency. ⋯ In comparison with EASY CAP, Colibri functions for a longer period and it has a humidifier and a bacterial filter. Colibri is useful for emergency situations and anesthetic care.

[The effect of continuous epidural infusion of combination of buprenorphine and bupivacaine for postoperative pain relief using a portable 0.5 ml.h-1 type infuser with patient control module].
Using a portable 0.5 ml.h-1 type infuser with Patient Control Module (Baxter infuser BB+ PCM), we compared patients receiving continuous epidural infusion with patients using self controlled analgesia system for postoperative analgesia after upper abdominal surgery. Twenty-one patients were randomized into three groups: group I (n = 7) received 20 micrograms.h-1 of buprenorphine (Bu) with additional 20 micrograms of Bu; group II (n = 7) 20 micrograms.h-1 of Bu plus 1 mg.h-1 of bupivacaine (Bup) with additional 20 micrograms of Bu plus 1 mg of Bup; group III (n = 7) 20 micrograms.h-1 of Bu plus 2 mg.h-1 of Bup with additional 20 micrograms of Bu plus 2 mg of Bup. In all three groups, patients received supplemental Bu 0.1 mg intramuscularly as needed. ⋯ There was no significant difference in verbal descriptor pain scale, sedative scale, visual analogue scale, and the incidence of side-effect among the three groups. Continuous epidural infusion with Bu using a portable 0.5 ml.h-1 type infuser with patient control module was effective for alleviating postoperative pain except in the first 12-hour period. However, addition of Bup to Bu did not improve the quality of postoperative epidural analgesia.

[Pre-emptive analgesia from intravenous administration of opioid: no effect with pentazocine].
The influence of timing of administration of preoperative pentazocine on pain and analgesic requirements after surgery was studied in 46 patients undergoing total abdominal hysterectomy. Twenty-three patients received thiamylal 5 mg.kg-1 on induction of anesthesia, followed by pentazocine 30 mg or 60 mg before surgical incision (group A). Twenty-three control patients received pentazocine 30 mg or 60 mg, 5 min after abdominal incision (group B). ⋯ There were no differences in the visual analogues scales. Pentazocine consumption in the first 24 h after surgery was 67.5 mg at 30 mg dose in group A or 52.5 mg at 60 mg dose in group A and 70.9 mg at 30 mg dose in group B or 51.8 mg at 60 mg dose in group B. We conclude that postoperative pentazocine consumption and pain scores are no different when pentazocine is given before or after skin incision for abdominal hysterectomy and that there is no clinically useful pre-emptive analgesic effect with these doses of pentazocine.

In order to evaluate both the knowledge and the degree of competence acquired by anesthesiology trainees, we constructed a checklist and began using it in January 1994. Twenty-one trainees participated in a 3-month program ending in February 1995. By means of the checklist, we attempted to evaluate the extent of their individual attainment. ⋯ The total anesthesia time was 212.0 +/- 32.8 hours, and 76.2 % of the anesthesia methods applied involved either nitrous oxide-sevoflurane or nitrous oxide-isoflurane. Using a 5-level rating scale, the self-assessment by the supervising doctor tended to be one point higher than the assessment by the trainees. We plan to improve this checklist to improve the results of training.

We present a rare case involving a broken suction catheter that became lodged in the tracheobronchial tree. An eight-month-old infant was scheduled for hernioplasty. Following intubation with a 4 French (Fr.) endotracheal tube, a 5 Fr. reused suction catheter was applied for suctioning a moderate amount of secretion. ⋯ At the breaking point, half of the cross section was very smooth and looked as if it had been cut by a razor, while the other half appeared to have been broken by pulling. The break may have started from the crack which had occurred at the insertion or resterilization. Therefore, we should restrict the reuse of small suction catheters, and should always utilize the catheter of the largest size possible.
