제왕절개술 마취에 대한 임상적 고찰

권창재,박춘남,문영화 대한마취과학회 1976 Korean Journal of Anesthesiology Vol.9 No.2

Maternal and fetal effects of anesthesia for 781 cases ceasarean sections, performed during the past 10 years (1965~1974) in Hanil Hospital have been evaluated clinically. It is emphasized that the selection of anesthetic agents and methods, should depend upon the physical status of the patients and the ability of both obstetricians and anesthesiologists. Optimal results require effective teamwork amongst obstetriciansm anesthesiologists and nursing personnel. The anethesiologist should be fully infermed of obstetric aspects. A variety of anesthetic techniques can be used for elective and emergency Caesarean sections. Each technique has its own adventages, disadvantages and limitations which must be thoroughly understood for proper application. The choice of anesthesia should be determined primarily by the experience of the operator, the degree of ugency, condition of the monther and fetus, the physiopathology, the skill of the obstetrician and the desires and the emotional state of the monther.

재왕절개술후 발생한 저온당증 1 례 보고

Little has been reported concerning post-operative hypoglycemia in previously asymptomatic individuals. Post-operative hypoglycemic coma is one of the most perplexing problems and must be differentiated from other conditions accompaning coma. We experienced a case of hypoglycemia following emergency cesarean section in primigravida with cephalopelvic disproportion on the fourth post operative day. The comatous state appeared abruptly and developed repeatedly. The causes of post-hypoglycemic coma are discussed and the prolonged starvation before and after operation was suspected to be the cause of coma.

수술중 Lactated Ringer 수액에 관한 임상적 고찰

권창재 대한마취과학회 1968 Korean Journal of Anesthesiology Vol.1 No.1

Our own preliminary experiences with the use of lactated Ringer solution during major surgery have been reported. We used 10cc/kg/hr in 40 patients throughout the operative period, and compared them with a control group of 30. Observations were made for the following; RBC, Hct, Hgb, electrolytes, and urine output. There were no significant differences in blood constituents and electrolytes between the two groups, but considerable increase in urinary outupt was noticed in the experimental group during 24 hour post-operative period. Blood transfusion had been done to replace blood loss and the experimental group had considerable reduction of transfused blood volume during surgery. We accept and produce evidence for the concept, pronounced by Epstein, that decrease in functional rextra-cellular fluid is a major determinant to sodium excretion. A major limitation of post-operative sodium excretion seemed to be the acute contraction of the functional extracelluar fluid incurred by surgery. If the losses of extracellular fluid were replaced during the operation, the phenomenon of sodium retention, was not seen. Neither normal saline nor 5% dextrose adequately replace the extracellular loss and kidneys do not eliminate excess water in this way. Lactated Ringer solution prevents acidosis and concomittant retention of water and sodium, and at the same time, sodium is adequately eliminated. It appears that this is an advance in managing fluid and electrolyte balance during surgery.

Transient hyperkalemia is well known to occur in man following intravenous administration of succinylcholine chloride. We studied the change of the serum potassium concentration after injection of succinylcholine in nonburn patients and electricburn patients, physical status 1 or 2 adopted by the American Society of Anesthesiologists. We compared two groups; Non-burn patient group(Group 1) as control, Electric burn patient group(Group 2) as experimental. The following results were obtained; 1) In non-burn patient group(Group 1)serum potassium concentration was slightly decreased in the 1st, 2nd, 3rd, 4th, 5th, 6th and 10th minute after succinycholine injection compared with control, but nostatistical significance was noticed in this group. 2) In electric burn patient group (Group 2) serum potassium concentration was maximally increased at the 2nd and 3rd minute after succinylcholine injection and the others were slightly increased compared with the controls. Statistical significance was noticed at the 2nd and 3rd minute after succinylcholine injection in this group.

We have analysed 72 cases of geriatric patients over 70 year of age who underwent anesthesia in our Aospital from Jan. 1970 to May 1979 and the results were as follows; 1) Male patients were more than female(1.05: 1). (Male, 37 cases(51.4%) and female, 35cases (48. 6%). 2) By ASA classification, physical status was class II in 32 cases, E II in 24 cases, III in 12 cases, E III in 2 cases and IV in 2 eases. 3) The number of the patients of general surgery department(46.63%) was highest. 4) Preoperative problems were cardiovascular diseases including hypertension (11cases) and LVH(25 cases), arrhythmia(6cases), tachycardia(4cases), RBBB(2cases) and bradycardia (2 cases) in EKG. 5) Preoperative pulmonary disease including pulmonary tbc(14 cases), chronic bronchitis (6 cases), and emphysema(4 cases) was revealed in the chest PA. 6) There was no mortality during the operative or postoperative period.

수술중 사용한 수액(5 % Dextrose solution 과 Hartmann`s solution)이 산-염기 평형에 미치는 영향

This preliminary study was intended to clarify the effect of intraoperative fluid therapy on Acid-Base balance of tbe use of Hartmann's solution and 5% Dextrose solution. The arterial carbon dioxide partial pressure and oxygen partial pressure and pH are basic indices of the adequacy of ventilation in anesthetized patients, respiratory care and intensive care. In order to achieve this goal, the data collections were done at the Department of Anesthesia in Hanil Hospital from Mar., 1980 to Aug., 1980. The samplings, 20 cases, were included A.S.A. class I and II. We used 1,500 to 1,800cc/2hrs. of Hartmann's solution and 1,000cc/2hrs, of 5% Dextrose solution each 10 patients through the operative period. Observations were made for the followings; pH, PaCO₂HCO-₃. From the results of this study, there were no significant relationship between the use of 5% Dextrose solution and Hartmann's solution on Acid-Base balance during the intraoperative period.

Catecholamine-심부정맥에 미치는 Propanidid 의 항부정맥작용에 관한 실험적연구

Cardiac arrhythmias were produced in the dog by injections of epinephrine or isoproterenol during intravenous thiopental or propanidid anesthesia. Propanidid did not increase the pressor response to epinephrine, reduce the depressor response to isoproterenol, or diminish the tachycardia following epinephrine or isoproterenol. Propanidid, however, consistently increased the arrhythmia threshold doses of epinephrine and isoproterenol four times those during thiopental anesthesia. It is concluded, therefore, that the antiarrhythmic effect of propanidid is not related to beta adremergic blockade but to its local anesthetic or quinidine-like action and that propanidid is an excellent intravenous anesthetic in view of its antiarrhythmic action on the heart.
