김태요,정경술 대한마취과학회 1988 Korean Journal of Anesthesiology Vol.21 No.3
We define acute respiratory failure(ARF) as present whenever the ratio of arterial oxygen tension (PaO_2) and inspired oxygen concentration (Fio_2) is below the normal predicted range for the patient's age and/or the arterial carbon dioxide tension (PaCO_2) is above 45 in the absence of respiratory compention for metabolic alkalosis. Adult respiratory distress syndrome (ARDS) which is associated with shock, trauma, infection, inhalation of toxic gas, aspiration of gastric content and drugs etc, first received. wide-spread attention in 1967. ARDS is a descriptive term that is characterized by a combination of refractory hypoxemia and severly decreased lung compliance. Numerous specific incidents or illnesses may be complicated by, or ssockated with ARDS . Early diagnosis and improvement in physiological therapy including PEEP therapy have been successful in treating the early and mild episodes of ARDS. This report describes three cases of ARF following anesthesia and reviews the literature.

Preoxygenation is routine preior to induction of general ancsthesia for the purpose of maintaining oxygenation during laryngoscopy and tracheal intubation. A common method of preoxygenation is 3∼5 minutes of 100% O_2 breathing. In some emergency states, there may not be adequate time for a full 3-5 min of preoxygenation. Recently, Gold and some others showed that four maximally deep inspirations of 100% O_2 within 30 seconds are as effective as 5minutes of inhaltion of 100% O_2 for increasing the PaO_2 We compared the changes of arterial blood gas beween a group which took deep breaths for 1 mimute with 100% O_2 and a group breathing spontaneously for 5 minutes with 100% O_2.

개심술시 사용한 고용량 Morphine 마취가 혈장 Atrial Natriuretic Peptide 농도 Renin 활성도 및 신장기능에 미치는 영향
이상호,김태요,송윤강,정경술 대한마취과학회 1989 Korean Journal of Anesthesiology Vol.22 No.1
Recent research has led to the discovery and characterization of a hormone secreted by the atria that has powerful vasopressive and natriuretic properties. Various atrial natriuretic peptides(ANP) were isolated and synthetized, and the effects were investigated by many workers. This study was attempted to access the effects of high dose morphine anesthesia on the plasma ANP level, renin activity and renal function in patients with cardiac surgery. Anesthesia was induced with morphine and maintained with 50% nitrous oxide in oxygen. Supple-mentary dose of morphine was given during the anesthesia according to responses of patients. The results were as follows: 1) The blood pressure and heart rate were not chaged significantly during anesthesia compared with the control values. 2) There was no statistically signigicant difference of plasma ANP level compared with the control values. 3) The plasma concentration of renin was markedly elevated after 30 minutes of induction time and sustained it during the anesthesia. Recovery to normal range of plasma renin concentration was observed after 2 days of surgery. This change is much the same as the other anesthetic methods. 4) Tendency of decreasing urine volume was shown just after the induction period but restored to control level immediately. 5) The renal excretory rate of sodium chloride and fractional excretion of sodium was significantly decreased during anesthesia and restored to control level after surgery. These results show that morphine anesthesia dose not produce significant alteration of both ANP and renin-angiotensin system.
