Background: In using the Double-lumen tube(DLT), knowing the minimum bronchial cuff volume (MCV) for an effective air-tight seal will be useful; to provide a collapse of the lung; and to avoid pressure damage. The aims of the present study are thus three-fold: to measure the MCV; to measure the diameter of left main bronchus(LMBD); and to prove any relationships between two parameters. Methods: One hundred men and forty women who needed intubation of left-sided DLT were enrolled in this study. 37 Fr DLTs were used in male patients, and 35 Fr DLTs were used in female patients. We evaluated the MCV by air bubble method and measured the LMBD in chest PA. We also evaluated the pressure/volume characteristics of the bronchial cuffs by control inflator. Results: 29 patients of 100 patients(29%) exhibited persistent air leakage in 2.5 ml cuff volume in male patients(group of MCV >2.5). On the contrary, 18 patients of 40 patients(45%) did not require any cuff volume in female patients(group of MCV 0). The mean LMD were 13.23 1.45 mm in male and 11.09 0.96 mm in female. There were significant positive correlations between MCV and LMBD in both sex and their respective correlation coefficients were 0.264(P=0.008) in male and 0.484(P=0.002) in female. The equations of linear regression were: LMBD = 12.394 0.429×MCV in male, LMBD = 10.725 0.438×MCV in female. Conclusions: The MCV of the brochial cuffs in left-sided DLTs has significant relationships with the LMBD measured in chest PA. (Korean J Anesthesiol 1997; 33: 849∼857)

Background : Carotid endarterectomy is a very high risk operation, combined with high incidence of stroke and myocardial infarction. We experienced 36 cases of carotid endarterectomies during the last two years. We reviewed these cases with anesthetic management and neurologic monitoring. Methods : All of the operations were performed under general anesthesia. 33 cases were monitored by EEG and SEP. We maintained cerebral perfusion during cross-clamping and shunt by normothermia, normocarbia and mild hypertension. Results : 33% of the patients had severe coronary artery stenosis and 41% had severe contralateral carotid artery stenosis preoperatively. During the operation, 10 patients showed transient EEG changes without SEP change or neurologic sequele. The major postoperative complication was myocarial infarction in one patient. There were 3 cases of postoperative cerebral infarction in radiologic findings. One case occurred after myocardial infarction and the other two cases showed no clinical evidence of neurologic deficit. Conclusions : In anesthetic management of carotid endarterectomy patients, maintaining cerebral perfusion, preventing perioperative myocardial infarction are important and monitoring neurologic function with EEG and SEP should be considered to prevent neurologic deficits.

Background : Surgery cause alterations in immune and neuroendocrine responses. Cytokines and stress hormones are importanat mediators which modulate the various immune reactions. The aim of present study is to investigate whether clonidine premedication can affect on the concentrations of cytokines and stress hormones in abdominal hysterectomy patients. Methods : Twenty two healthy women undergoing abdominal hysterectomy were randomly allocated to two groups: eleven control patients and eleven clonidine(0.15 mg) pretreated patients. Variations in blood cytokines, Interleukin-1 (IL-1 ), IL-2, IL-6 and tumor necrosis factor- (TNF- ), and stress hormones, cortisol and ACTH were studied. Blood sampling were conducted 4 times in each patient: after induction, after incision, after surgery 1 h and 3 h. Cytokines assays were carried out with commercially available ELISA kits, and cortisol with radioimmunoassay and ACTH with immunoradiometric assay. Results : IL-1 increased early and the concentrations of IL-1 in clonidine treated group were significantly lower than control. The mean concentrations of IL-2 at 1 and 3 h after surgery were slightly higher than after induction in clonidine treated group. IL-6 increased significantly at 3 h after surgery in both groups. Clonidine lowered IL-6 during the whole period. TNF- , and cortisol and ACTH concentraitons were not affected by clonidin. Conclusions : Clonidine pretreatment decreased IL-1 and IL-6 concentrations, but not stress hormones in response to abdominal hysterectomy. (Korean J Anesthesiol 1998; 35: 327∼333)

In this study, in order to study the effects that the qualitative undernourishment of a gestation pig influences upon the fetal growth, we offered eight heads of gilt, Berkshire as material of experiment, and established experimental plots such as; control plot(C) hypo-protein plot(T), defferent plot of VA, inbalanced plot of Ca to P, and from the fifteenth of June to the twentieth of octeber in 1968 inseminated and fed them. After hiving been inseminated, they were killed just in 72 days (Block Ⅰ) and in 100 days (Block Ⅱ). in examining them, the state of the fetal growth is the following; 1. The number of conceptional pigs and the sex ratio of fetus are not recognized in each experimental plot. 2. There was no dead conceptionnal pig in C plot, and there were one head of dead conceptional pig in T1 plot, two heads in T2 plot, one head in T3 plot, amount to four heads of dead shotconceptinal pigs in all. 3. Deformities happened such as; two heads of dwarf in T1 plot, one head of eyeball-defect and one head of muscle-contracture inT2 plot, one head of duck-leg and one head of spine in T3 plot. 4. The average body-weight of a fetus was 286g in C plot, 229g in T1 plot, 254g in T2 and T3 plot, and the average body Legth of a fetus was 17.5㎝ in C plot, 13.8㎝ in T1 plot, 14.3㎝ in T2 plot, 14.2㎝ in T3 plot, and the average head length of a fetus was 7.4㎝ in C plot, 6.8㎝ in T1 plot, 7.2㎝ in T2 plot, 6.4㎝ in T3 plot and the average chest girth of fetus was 15.6㎝ in C plot, 12.9㎝ in T1 plot, 13.5㎝ in T2 plot, 13.1㎝ in T3 plot. As for the Block Ⅱ, the body-weight of a fetus was 797g in C plot, 700g in T1 plot 743g in T2 plot, 753g in T3 plot, and the body length was 26.8㎝ in C plot, 21.6㎝ in T1 plot, 23.7㎝ in T2 plot, 22.4㎝ in T3 plot, and the head length of a fetus was 9.3㎝ in C plot, 8.1㎝ in T1 plot, 9.1㎝ in T2 plot, 6.4㎝ in T3 plot, and the chest- girth was 23.815.6㎝ in C plot, 19.7㎝ in T1 plot, 21.0㎝ in T2 plot, 20.4㎝ in T3 plot. 5. When we set the average size of a fetus of C plot, as 100, in Block Ⅰ, the proportional boby weight was 80 in T1 plot 89 in T2 and T3 plot, the proportional body length was 79 in T1 plot, 81 in T2 and T3 plot, and the proportional head-length was 92 in T1 plot, 97 in t2 plot, 86 in T3 plot, and the proportional chest-girth was 83 in T1 plot, 87 in T2 plot, 84 in T3 plot, but in Block Ⅱ a little increasedrate was recognized. As a whole, there was'nt great difference between the plots in the size and the head length of a fetus. And there were gret differences in the body weight and body-length and the chest-girth between control polt and T1 plot, We also could see great difference in the body-length between C and T2 plot, and in the body-length and the chest-girth between C and T3 plot. 6. When we saw the state of a fetal growth with our naked eyes, in T1 and T2 plot, the growth of hind-part of body and the state of skin were in bad condition, and in T3 plot the growth of the limbs, skeltone, skin, teeth was also in bad condition. 7. The efficiency of the body weight of a gestation pig was 119% in C plot, of Block Ⅰ (130% in C plot, of Block Ⅱ) and comparatvely low-rate in T1 plot, but there was'nt great difference between the control plot and the treatment plot.
