Backgound: The effect of anesthetic techniques, such as closed circuit anesthesia (CCA) using semiclosed circuit system and semiclosed circuit anesthesia (SCCA), on the work of breathing has not been studied yet in detail. This study was purposed to compare the work of breathing according to anesthetic technique (CCA, SCCA). Methods: Thirty patients were assigned to receive either SCCA group or CCA group (n = 15). Anesthesia was induced with propofol 2 mg/kg with 2% lidocaine 1 ml. Two percents isoflurane with O2 and N2O 2 L/min were given for 10 min to patients initially to wash in functional residual capacity and the breathing circuits. In SCCA group, anesthesia was maintained with 2% isoflurane in O2 2 L/min and N2O 2 L/min throughout the surgery. In CCA group, O2 was reduced to 200 ml/min and N2O to 100 ml/min with isoflurane vaporizer setting adjusted to 4% for anesthesia maintenance. When the operation was ended, the vaporizer setting of isoflurane deceased to zero and then O2 was increased to 4 L/min for the arousal of the patient. We measured the inspiratory/expiratory concentration of isoflurane, end-tidal CO2, the hemodynamic parameters, the change of airway pressure, the work of breathing, and compliance at anesthetic induction and emergence in both groups. Results: There were no significant differences in the inspiratory/expiratory concentrations of isoflurane, the hemodynamic parameters, end-tidal CO2, airway pressure, the work of breathing and compliance between the groups. Conclusions: CCA using semiclosed circuit system does not increase the work of breathing compared to SCCA. (Korean J Anesthesiol 2006; 50: 495~500)

In this study, treatment with Dendropanax morbifera leaves pre treated with regular treatment, post-treatment and observation of the morphological changes of the hair wave efficiency showed a significant difference in the wave shown the highest efficiency of D-2 49.48 ± 0.36% (p <.001), the measurement of the tensile strength Dendropanax morbifera leaves after the treatment process, and the tensile strength of hair 108.95 ± 17.43 gf/mm² in the highest. As a result of measuring the thickness of the control group cuticle decreased thickness is 315.40 ± 17.23 nm in thickness compared to the experiment before the cuticle hair, in the experimental group was pre-treated for treatments cuticle thickness of D-1 was measured with 430.33 ± 28.24 nm, Treatment after the thickness of the treated garment cuticle D-2 454.87 ± 10.93 nm as shown significant differences were highest between the control group and the experimental group (p <.001). The efficacy in this study as compared to normal hair treatments of treatment was added Dendropanax morbifera leaves wave efficiency of the hair damage was observed that.

Background: The purpose of this study was to investigate whether muscle relaxant affect the values of Entropy, response entropy (RE) or state entropy (SE) during propofol anesthesia. Methods: Eighty patients (ASA I) scheduled for elective surgery under general anesthesia were randomly assigned to four groups. Anesthesia was maintained at a SE value of 80 (80±2) using target controlled infusion (TCI) of propofol. After maintaining SE 80 for 5 min, vecuronium 0.1 mg/kg was injected intravenously in group I and same volume of normal saline was intravenously injected in group II. After maintaining SE 60 for 5 min, vecuronium 0.1 mg/kg was injected intravenously in group III and same volume of normal saline was injected intravenously in group IV. The mean arterial pressure, heart rate, SE and RE were measured before anesthetic induction and up to 5 min after vecuronium or normal saline injection in each group. Results: SE and RE were not changed in group II, but significantly decreased in group I (P<0.05, respectively). In group III and IV, SE and RE were not changed in both groups. There were no significant hemodynamic changes among the four groups. Conclusions: These results suggest that the effect of muscle relaxant on Entropy vary according to the baseline values of RE or SE during propofol anesthesia. (Korean J Anesthesiol 2009;56:381~6)
증례보고 : 전폐절제술 후 심폐소생술 시 발생한 좌심실 파열

We report a case of circulatory collapse and cardiac arrest immediately after the patient was turned from the lateral decubitus position to the supine position following left pneumonectomy. Closed-chest resuscitation with medical and fluid interventions were inadequate. Emergency chest showed the deviation of heart to the left side and blunted apex. Left ventricular rupture during resuscitation was found subsequent thoracotomy. This rupture and inadequacy of closed-chest resuscitation were felt to be associated with the operative pneumonectomy and pericardiotomy. (Korean J Anesthesiol 2007; 53: 123~6)

Background: Laryngoscopy, tracheal intubation and suspension laryngoscopy may cause acute hemodynamic responses such as hypertension and tachycardia. Thus, anesthetic technique during laryngoscopic surgery should be focused on sufficient anesthetic depth and rapid recovery. We investigated the effects of alfentanil to hemodynamic responses and recovery during laryngoscopic surgery. Methods: Seventy five patients of ASA class 1 or 2 scheduled for laryngoscopic surgery were randomly divided into three groups. Each group received intravenous normal saline 2 ml (control group), alfentanil 10μg/kg (A10 group), alfentanil 20μg/kg (A20 group) respectively and then followed by induction of thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg. The systolic blood pressure, diastolic blood pressure, heart rate were measured at baseline, immediately and 1 minute after intubation, immediately and 1, 2, 3 minutes after placement of suspension laryngoscopy. The time of suction catheter response, eye opening and extubation were evaluated during recovery periods. Results: The hemodynamic responses to tracheal intubation were blocked in the A10, A20 groups compared with control group. But the hemodynamic responses to placement of suspension laryngoscopy were blocked only by A20 group. The time of eye opening and extubation were no significant differences among groups. Conclusions: Alfentanil 20μg/kg effectively alleviate the hemodynamic responses by tracheal intubation and suspension laryngoscopy during laryngoscopic surgery.
