Parasystole is of special interest among the disturbances of ectopic impulse formatioo. First, a parasystolic arrhythmia is of clinical importance because the ventricular origin ordinarily indicates the presence of organic heart disease. Second, parasystole, although not rare, is frequently overlooked because it is difficult to be differentiated from extrasystole. In this paper a ventricular parasystole is presented. A 48 year-old woman was seen with an irregular pulse rate not accompanying cardiac symptoms or signs. The chest radiograph failed to show cardiomegaly. E.K.G. revealed the dominant rhythm of sinus origin with intermittent ventricular parasystolic beats. The basic rhythm was sinus with a rate of 83 per minute. The coupling interval varied between 0.52 & 0.7 second. The shortest, calculated interectopic interval ranged from 45.2 to 49.7 (These numbers represent hundreds of a second). Occasional ventricular fusion beats appeared. She was uneventfully nephrectomized under general anesthesia with halothane-N2O-O₂for left renal empyema of tuberculosis. She dispensed well with any antiarrhythmic agent during admission

Since succinyl choline was introduced, into clinical anesthesia, it has been used as main muscle relaxant because of its rare side effects and short duration of action. Our interest in the effects of this drug on extraocular muscles and intraocular pressure began in 1957 following reports of vitreous expulsion in patients who received succinylcholine during ocular surgery. The effects of muscle relaxants on the intraocular pressure were studied in 60 healthy human sub jects. When succinylcholine was given alone, 20 human subjcts had a mean increase in intraocular pressure of 10. 5 mmHg. When gallamine 2. 5 mg/kg or pancuronium 80 μg/kg was used, 20 subjects showed a mean decrease of 3. 1 mm Hg from control. Giving gallamine (20 mg) or dtubo curarine(3 mg) 2-3 minutes prior to the administration of succinylcholine, 20 human subjects had no significant change in intraocular pressue. This simple method prevents the increase in intraocular pressure associated with the use of succinylcholine.

Bragg의 용량-반응-시간모형으로 rocuronium의 동학-약역학모수의 추정과 모의실험

이수일,정찬종,이승철,장정훈 대한마취통증의학회 2011 Anesthesia and pain medicine Vol.6 No.1

Background:The effect-time data involves some pharmacokinetic (PK) information. Bragg model could derive the information from pharmacodynamic (PD) data alone. After administering rocuronium, we collected tension data without these plasma concentration values. We determined kinetic-pharmacodynamic (K-PD) parameters, simulated the predictions of effect-time relation at different amount of dose, and validated the calculated infusion rates (IR) by comparing with IR directly measured. Methods: Thirteen dexterous male patients were given rocuronium 300μg/kg during propofol-fentanyl anesthesia. Twitch tensions of the right adductor pollicis in response to supramaximal single twitch stimulation every 10 seconds were measured until muscle paralysis recovered by 70 ± 10% of control. The above data were fitted to Bragg equation, using Tablecurve3DⓇ. The parameters, k1, k2, IR50, and γ, were derived with either individual regression or population regression. The correlations between individual parameter and time, the simulation, and validation by infusing rocuronium 3.66μg/kg/min were examined. Results: Based on population regression, IR50 was 3.70μg/kg/min, γ was 4.51, k1 (keo) was 0.71/min, and k2 (k10) was 0.022/min. The longer the duration of rocuronium action was, the smaller the values of IR50 and k2 were (correlation coefficient: −0.92, −0.61, respectively). ED50 calculated (= IR50/k2) was 168μg/kg. The effects of rocuronium 3.66μg/kg/min were estimated (45% by direct measurement, 49% by population parameters, and 21% by individual parameters). Conclusions: The results of infusion rate validation suggests that population parameters may better be applicable than individual post hoc parameters to predicting the clinically relevant effect-time relations.(Anesth Pain Med 2011; 6: 67∼74)

방송사업의 소유겸영규제 개선

This paper uses the horizontal regulation system as the base analysis framework. The study clearly defines the regulatory goals of the followings: the horizontal cross-ownership regulations on program provider (PP) and platform provider, the vertical regulation on cross-ownership between PP and platform operator, the regulation on cross-ownership of program provider by terrestrial broadcasting company, and the regulation on cross-ownership between terrestrial broadcasting company and platform provider. Then, by analyzing the conformity between goals and criteria of regulations and the adequacy of the regulation level according to regulatory purposes, this paper examines the justifiability of each regulation and extracts improvement measures that suite regulatory purposes. This analysis finds following appropriate measures: replacing the horizontal cross-ownership regulation on PP with conduct regulations, such as designating major broadcasting programs or replacing the current criterion of cross-ownership regulation from sales to the audience market share; reshaping the horizontal cross-ownership regulation on platform provider so that system operator (SO), satellite broadcaster and Internet protocol television (IPTV) operator would be applied by the same regulation based on the number of subscribers of pay television services; and discontinuing other cross-ownership regulation. In this way, the study shows that with appropriate regulations on cross-ownership of PP, there would be no need for additional regulation on vertical integration between PP and platform operator. On the other hand, given that the regulation on terrestrial broadcasting cross-ownership of PP could be justified only by regulatory purpose of the protection of the diversity of public opinions, it would be desirable to replace the current criteria of the number of PPs with the criteria of the audience market share. Lastly, the study shows that when platform operator is targeted by the cross-ownership regulation based on the number of subscribers of pay television services, the regulation on cross-ownership between terrestrial broadcasting company and platform provider should be replaced with conduct regulations, such as designating must-offer channels and major broadcasting programs. 본 논문은 수평적 규제체계를 분석의 준거 틀로 하여 방송채널사용사업자(PP)에 대한 수평적 소유겸영규제, 플랫폼사업자에 대한 수평적 소유겸영규제, PP와 플랫폼사업자 간 수직적 소유겸영규제, 지상파방송사의 PP 겸영규제, 지상파방송사와 플랫폼사업자 간 소유겸영규제 각각에 대하여 규제목적을 명확히 설정하고, 규제 목적과 규제기준의 정합성, 규제목적에 따른 규제수준의 적정성을 분석함으로써, 각 규제의 타당성을 검토하고 규제목적에 부합하는 개선방안을 도출하였다. 분석 결과, PP에 대한 수평적 소유겸영규제는 주요 방송프로그램의 지정 등 행위규제로 대체하거나 소유겸영규제의 기준을 현행 매출액에서 시청점유율로 변경하고, 플랫폼사업자에 대한 수평적 소유겸영규제는 종합유선방송사업자(SO), 위성방송사업자, IPTV사업자에게 유료방송 가입자 수를 기준으로 하는 동일한 소유겸영규제를 적용하고, 여타의 소유겸영규제는 폐지하는 것이 타당함을 보였다. 이와 같이 PP와 플랫폼사업자에 대해 적정한 소유겸영규제가 설계된 상태에서는 별도로 PP와 플랫폼사업자 간 수직결합을 규제하는 것이 불필요함도 보였다. 한편, 지상파방송사의 PP 겸영규제는 여론의 다양성 보호라는 규제목적에서만 정당화될 수 있으므로, 현행 PP 사업자 수의 기준은 시청점유율 기준으로 변경하는 것이 합리적이다. 마지막으로 플랫폼사업자에게 유료방송 가입자 수를 기준으로 한 소유겸영규제가 설계되는 경우, 지상파방송사와 플랫폼사업자 간 소유겸영규제는 의무제공(must offer)채널 지정, 주요 방송프로그램 지정 등 행위규제로 대체되어야 함을 보였다.
