Mivacurium과 Vecuronium의 혼합 사용이 전신마취 중 근이완에 미치는 영향
임정애,채화주,최영길,우남식 대한마취과학회 1999 Korean Journal of Anesthesiology Vol.37 No.1
Background: This study was designed to examine the interactions between mivacurium and vecuronium when administered during a standardized technique. Methods: Eighty patients (ASA physical status I or II) were randomly assigned to one of four groups (n=20). Their neuromuscular function was measured in response to ulnar nerve supramaximal square-wave TOF stimulation at 10-sec intervals. After the attainment of a stable baseline neuromuscular response, the patients were randomly assigned to receive a rapid iv bolus of either: (1) 3M group (n=20): mivacurium 0.21 mg/kg. Alone, or (2) 2M1V group (n=20): mivacurium 0.14 mg/kg plus vecuronium 0.05 mg/kg, or (3) 1M2V group (n=20): mivacurium 0.07 mg/kg plus vecuronium 0.10 mg/kg, or (4) 3V group (n=20): vecuronium 0.15 mg/kg alone. The onset time of the neuromuscular block, time of recovery of T1 to 25% and reblock time (the time from the reinjection of vecuronium at the time of recovery of T1 to 25% to the time of recovery of T1 to 25%: T25-25) were measured. The intubating condition was evaluated clinically with a scoring system. Results: The onset of block in the 3M group was 33% slower than in the 3V group. The time durations until 25% recovery in the 2M1V, 1M2V and 3V groups were longer than in the 3M group, and the durations in the 1M2V and 3V groups were longer than in the 2M1V group. The T25-25 reblock times of the 2M1V, 1M2V and 3V groups were prolonged in comparison to that of the 3M group. There was no difference in intubating conditions between any of the groups. Conclusions: A combination of mivacurium with vecuronium provides rates of onset and duration of block which are more effective than an equivalent dose of mivacuriun alone as an additive reaction.

액체 Na-heparin 과 분말 Li-heparin 이 혈액 가스 분석과 혈색소 및 전해질 측정에 미치는 영향

Arterial blood gas analysis is essential laboratory test in monitoring of acid-base balance and respiratory care, but it has been known that there was many variabilities according to method of sampling and care before analysis. We compared the effects of liquid Na heparin and dry Li-heparin on blood gas analysis, hemoglobin and electrolytes, and studied in 25 patients who were taken elective operation with radial arterial eannulation. The samples were obtained from radial artery; sample 1, drawn to a total volume of 1 cc with 2cc plastic syringe utilizing liquid Na-heparin; sample 2, drawn to a total volume of 2 cc with 2 cc plastic syringe utilizing liquid Na-heparin ; sample 3, drawn to a total volume of 1 cc with Bard parker Preset 1 cc kit that pre-filled dry Li-heparin; control value, sampled arterial blood without heparin for measurement of hemoglobin and electrolytes. These samples were analyzed with minimum error, as possible. We obtained the following results. 1) There was no atatistical difference in pH, PCO₂, PO₂ and hemoglobin in each sample. 2) The value of Na+ and K+ were no statistical differences in sample 1,2 and 3, but sig- nificantly lower level than control value (P$lt;0.01). 3) The Ca^(2+) level was significantly lower in sample 1 and 2(P$lt;0.01) and not significantly different in sample 3 when compared with the control value. The Ca level was significantly higher in sample 2 and 3 when compared with sample 1 (P$lt;0.01). So we conclude that arterial blood gas analysis and hemoglobin level showed no statistical difference between the liquid Na heparin and the dry Li-heparin. Heparin is not suitable for Na^+ and K^+ measurement. Low dose liquid Na heparin and dry Li heparin is reliable for obtaining Ca^(2+) level.

이 연구는 전과정평가 및 비용분석을 통하여 제품을 구성하는 설계요소별(재질/부품 별)로 정량적인 값을 도출하고 환경/비용 분석도를 활용함으로서 제품 폐기단계에서 우선적으로 개선하여야 할 인자를 파악하는 과정을 제시하였다. 또한 아산 리사이클링 센터에서 처리되는 540ℓ급 냉장고 폐기과정의 환경성 및 비용흐름을 분석하여 우선적으로 개선되어야 할 요소를 파악하였다. 폐 우레탄의 소각, 기타플라스틱의 소각 등이 환경적 측면 및 비용 측면 동시에 가장 우선적인 개선인자로 파악되었고 냉매의 처리과정이 환경적 측면에서, Steel 및 ABS가 비용 측면에서 우선적인 개선 인자로 파악되었다. Steel과 ABS의 중량은 운송과정의 비용요인과 밀접한 관계가 있으며 이를 위해 경량화 설계, 운송경로 최적화 등이 개선전략이 될 수 있다. 냉매인 R-134a는 지구온난화에 영향을 미치면서 재활용은 불가한 속성 때문에 환경측면의 개선인자로 분석되었으며 이를 위해 냉매 재활용기술의 개발, 대체재의 개발 등이 시급하다. A systematic methodology for identifying improvement factors based on the analysis of environmental aspects with LCA and economic aspects with cost analysis during the disposal phase of a product was proposed in this study. The proposed methodology was applied to a discarded refrigerator. The improvement factors requiring highest priority include incineration of PUF and incineration of other plastics. Those requiring higher priority include recycling of steel and ABS with respect to the cost aspect, and refrigerant, R-134a to the environmental aspect. Weight of steel and ABS is the attribute of the refrigerator that causes problems in the cost aspects. Improvement strategies would include design for light weighted product and optimization for the waste disposal pathway. Global warming and recycling potential are two major attributes of refrigerant that cause problems in the environmental aspects. Improvement strategies would include the development of recycling technology, use of recyclable materials, and use of natural refrigerant that does not cause global warming.
