A new human sensibility (kansei) meter that can measure human sensibility at the indoor environment is developed in this paper. Four sensors that can measure temperature, humidity, CO₂ and C₄H_(10) concentrations are used. Among these sensors, the first three are used to determine the human sensibility, And the last to protect human from the harmful gas. First of all, human sensibilities are defined for each sensor datum, and then those are linearly combined to make a final human sensibility (kansei). The efficiency and usefulness of the meter are verified using a simulator on Windows 95 and a stand-alone system constructed using a microprocessor.
경요도 전립선절제술에서 척추마취 시 소용량 Bupivacaine-Fentanyl의 병용투여와 상용용량 Bupivacaine의 임상 효과 비교

Background: The combination of local anesthetics and opioids in the spinal anesthesia has a synergic analgesic effect, Therefore, we compated intraoperative conditions and clinical effects of low dose (5 mg) bupivacaine added with fentanyl versus a conventional dose(10 mg) of bupivacaine in spinal anesthesia for a transurethral resection of the prostate (TURP). Methods: Forty five ASA class 1 and 2 patients scheduled for a TURP were randomly divided into three groups. Group B (n = 15) received bupivacaine 10 mg, group BF (n = 15) received bupivacaine 5 mg added with fentanyl 20 ㎍, and group BFE received bupivacaine 5 mg added with fentanyl 20 ㎍ and 0.2 mg epinephrine. Blood pressure and heart rate were recorded every 5 minutes before and after spinal anesthesia. Sensory blockade was measured by a pin-prick test and motor blockade was evaluated by the Bromage motor scale. Side effects including pruritus, nausea, vomiting, respiratory depression, and intraoperative pain were observed. Results: The duration of sensory and motor blockade in group BF was significantly shorter than in group B and group BFE (P < 0.05). Without statistical significance, hypotension (6.7%) and bradycardia (13.3%) were observed in group B and pruritus (26.7%) and nausea (13.3%) occurred in all patients who received fentanyl. Conclusions: The addition of fentanyl 20 ㎍ to low dose bupivacaine 5 mg resulted in short lasting motor and sensory block, compared with conventional dose bupivacaine 10 mg. Therefore, we concluded that the clinical application of this method could provide adequate analgesia with early discharge and no serious side effects for TURP patients.

간 유입혈류 차단 후 간절제술 시 Isoflurane 과 Propofol 이 술 후 간기능에 미치는 영향 비교

Background : Anesthesia and surgery may exacerbate liver function in patients with pre-existing liver disease so it is important to choose less hepatotoxic anesthetics in patients with chronic liver disease. Methods : This study was designed to examine the postoperative liver function test in 150 patients after hepatectomy with portal triad clamping through retrospective chart review. Patients were divided into an isoflurane group (group I, n= 56) and a propofol group (group P, n = 57) by used anesthetics for maintaining anesthesia. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase, alkaiine phosphatase, total bilirubin, albumin, and prothrombin time were checked at preoperation, and postoperatively at 1, 3, 7 and 14 days in the two groups. Indocyanine retention rate (ICG-R15) was measured at preoperation, and postoperatively at 1 and 7 days. Results : AST values increased postoperatively at 1, 3, 7, and 14 days compared with preoperation. ALT values increased postoperatively at 1, 3 and 7 days compared with preoperation and there was difference between group I (443.8 ± 52,1 U/L) and group P (202.7 ± 24.7 U/L) at postoperative 1 day. Other values had no significant difference between the two groups. Conclusions : Though it might need a well controlled study to find the differences in effect between isoflurane and propofol on the postoperative liver function test, we concluded that total intravenous anesthesia using propofol is also one of the safest anesthetic methods for hepatic resection with minimal hepatotoxicity.
