Parameters of the left ventricular performance were evaluated by echocardiographic examination in 66 normal subjects. Effects of pulse rate, systemic arterial pressure, peripheral resistance and left ventricular end-diastolic dimension on the parameters were also observed. Normal value(mean+/-SD) of fractional shortening was 34.0+/-5.2%, ejection fraction 0.71+/-0.07, mean rate of circumferential fiber shortening 1.15+/-0.19 circ/sec, mean posterior wall velocity 4.05+/-0.70cm/sec, maximal posterior wall velocity 6.31+/-1.26cm/sec, mean normalized posterior wall velocity 0.82+/-0.14/sec, and maximal normalized posterior wall velocity 1.28+/-0.24/sec. There were negative correlations of peripheral resistance to fractional shortening, ejection fraction and mean rate of circumferential fiber shortening. Pulse rate and left ventricular end-diastolic dimension did not have significant effects on these parameters. Mean and maximal posterior wall velocity had negative correlations to peripheral resistance and positive correlations to left ventricular end-diastolic dimension. But mean and maximal normalized posterior wall velocity had no correlations to any of them.

5.Effect of Esmolol on Serum Potassium Changes Induced by Succinylcholine.
Korean Journal of Anesthesiology 1996;31(1):70-75
BACKGROUND: The purpose of this study was to determine whether esmolol augmented the increase in serum K+ following administration of succinylcholine. METHODS: Forty patients were randomly divided esmolol group (n=20) and control group (n=20). The esmolol group received a 1 minute rapid infusion of 500 mcg/kg/min followed by a continuous infusion of 200 mcg/kg/min for 4 minutes before administration of succinylcholine. Serum potassium level, mean arterial blood pressure and pulse rate were measured prior to induction(baseline) and 1, 3, 5, 10, 15, 30, 45, 60, 75, 90 minutes after administration of succinylcholine. RESULTS: Serum potassium level was significantly higher in esmolol group after 3 and 15 minutes after succinylcholine than control group. Mean arterial blood pressure was not significantly different between two groups except 10 minute but the pulse rate significantly lower 1, 3, 5, 10 and 15 minutes in esmolol group than control group. CONCLUSIONS: Esmolol does not significantly elevate serum potassium level in clinical use(1 minute infusion of 500 mcg/kg/min followed by infusion of 200 mcg/kg/min for 4 minutes) after administration of succinylcholine. So succinylcholine can be used safely in the presence of beta-1-selective adrenergic blockade. And esmolol can attenuate more effectively increase of pulse rate than mean arterial pressure.

BACKGROUND AND PURPOSE: Leptomeningeal collaterals maintain arterial perfusion in acute arterial occlusion but may fluctuate subject to arterial blood pressure (ABP). We aim to investigate the relationship between ABP and collaterals as assessed by computer tomography (CT) perfusion in acute ischemic stroke. METHODS: We retrospectively analyzed acute anterior circulation ischemic stroke patients with CT perfusion from 2009 to 2014. Collateral status using relative filling time delay (rFTD) determined by time delay of collateral-derived contrast opacification within the Sylvian fissure, from 0 seconds to unlimited count. The data were analyzed by zero-inflated negative binomial regression model including an appropriate interaction examining in the model in terms of occlusion location and onset-to-CT time (OCT). RESULTS: Two hundred and seventy patients were included. We found that increment of 10 mm Hg in BP, the odds that a patient would have rFTD equal to 0 seconds increased by 27.9% in systolic BP (SBP) (p=0.001), by 73.9% in diastolic BP (DBP) (p<0.001) and by 68.5% in mean BP (MBP) (p<0.001). For patients with rFTD not necessarily equal to 0 seconds, every 10 mm Hg increase in BP, there was a 7% decrease in expected count of seconds for rFTD in SBP (p=0.002), 10% decrease for rFTD in DBP and 11% decrease for rFTD in MBP. The arterial occlusion location and OCT showed no significant interaction in the BP-rFTD relationship (p>0.05). CONCLUSIONS: In acute ischemic stroke, higher ABP is possibly associated with improved leptomeningeal collaterals as identified by decreased rFTD.

Measurement of arterial preseure, either intermittently or continuously has teen used for almost 100 clears. A prospective study was conducted on 22 patients to compare the accuracy of arterial pressures treasured br a non-invasive (ACCUTORR,ACC) and an invasive (intra-arterial Line, IAL) arterial pressure monitoring systems. Overall, the accuracy or regroducibility of each method, as expressed in the individual variarlce, was shown to be statistically in significant between ACC and IA7. The difference in arterial pressures was particularly marked between ACC and IAL when srstalic BP was either less than 100 mmHg or greater than 140 mmHg.

9.Blood Pressure Changes After Implantation of Acrylie Cement into the Acetabulum and Proximal Femoral Shaft .
Korean Journal of Anesthesiology 1976;9(2):189-192
A fall in systemic arterial pressure after implantation of acrylic cement into the acetabulum and proximal femoral shaft in the surgery of total hip prosthesis was observed and also the following results were obtained in three cases of total hip prosthesis under general anesthesia. 1) Blood pressure was usually decreased immediately after implantation of acrylic cement and returned to normal level approximately within 5 minutes. 2) The marked fall in blood pressure was more often observed with the introduction of bone cement into the proximal femoral shaft but less with the acetabular implantation of bone cement. 3) It is urged to measure blood pressureat the minute interval immediately after insertion of bone cement.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.
