Authors performed a retrospective clinical and radiologic comparative study for 43 uncemented primary total hip arthroplasty which include 20 hips without lateral porous pad and 23 hips with lateral porous pad in same kinds of implant(Zimmer Anatomic") to investigate the role and significance of the lateral porous pad. The average follow up was 35 months and 38 months for without and with lateral porous pad respectively. The results were as followings: 1. Clinical and radiological results of group with and without lateral pad were similar together except incidence of radiolucency at zone 1 on anteroposterior radiograph in group without lateral pad was markedly higher compare to that in group with lateral pad. 2. The extent of lateral porous pad was not sufficiently enough to make better clinical and radiological results in stem with lateral pad compare to stem without lateral pad. 3. Stems without lateral porous pad had no evidence of bone ingrowth on lateral pad while stems with lateral pad had bone ingrowth on lateral pad with more than 50% in incidence. So, we think that presence and increase of extent of porous pad would have better clinical and radiological results.

BACKGROUND: Propofol is a useful induction agent, but it can cause hypotention and bradycardia. Meanwhile, ephedrine has alpha-vasoconstriction and beta-cardiac stimulant effect. The purpose of this study was to assess the hemodynamic effects of adding various doses of ephedrine to propofol to obtund adverse hemodynamic response and to determine the optimal dose. METHODS: Unpremedicated 120 ASA physical status I adult patients (20~50yrs) scheduled for elective surgery were randomly allocated into four groups according to the doses of ephedrine added to propofol (1%, 20 ml). Group 1 (control group) was given propofol alone and 10, 15 and 20 mg of ephedrine was added to propofol in Group 2, 3 and 4, respectively (n=30 for each group). Propofol was loaded at 150 ml/hr using a syringe pump and no response to verbal command was ascertained as the end-point of induction. Vital signs and SpO2 were checked every 1 min during the induction period. RESULTS: In group 1, there was a significant decrease in both systolic and diastolic pressure prior to intubation. Group 2 and 3 showed relatively stable hemodynamic changes and significant systolic or diastolic changes occured only in the pre or post 1 min periods of intubation. But, in pulse rate, group 3 showed significant change 1 and 2 min after intubation, in contrary to group 2. Group 4 showed significant changes in systolic and diastolic pressure 1 and 2 min after intubation, and in pulse rate throughout the postintubation period. CONCLUSIONS: Ephedrine 10mg may be safely employed to reduce the hemodynamic changes during induction preiod with propofol.

Of 86 Korean patients with recurrent spontaneous panic attacks, not one had definite mitral valve prolapse (MVP). With a very low prevalence of MVP in the general Korean population, this finding suggests that MVP may not be specifically associated with panic attack.

BACKGROUND: To estimate real time concentration of drugs during TIVA is theoretical, but it is not easy and inefficient. To maintain designed target concentration with continuous infusion using methods that account for the multicompartmental pharmacokinetic profile of fentanyl, isoconcentration nomogram is one of the methods. We evaluated the clinical usefulness of the isoconcentration nomogram using two different expected concentration of fentanyl. METHODS: Thirty ASA class I or II adult patients scheduled for spine fusion were randomly allocated into two groups according to 1.5 or 3 ng/ml of expected fentanyl concentration. Using isoconcentration nomogram, fentanyl concentration was adjusted and the propofol concentration was fixed to 3.5 g/ml according to Prys-Roberts method. Vital signs were titrated using variable flow rate of propofol. Fentanyl and propofol were discontinued 15 min before the end of operation. And, IV-PCA using fentanyl were applicated for postoperative pain control. The dosage of propofol and fentanyl, recovery time of consciousness and orientation were checked. Also, first buttoning time and 24hr fentanyl dosage in IV-PCA were checked. RESULTS: Average flow rate of propofol used were 7.5 1.2 mg/kg/hr in group 1, 5.7 1.1 mg/kg/hr in group 2 which was significantly lower than group 1 (p<0.05). Spontaneous eye opening and recovery of orientation was delayed 1.8 times in group 2. First buttoning time and 24hr fentanyl requirement for postoperative pain control using IV-PCA was delayed by 2 and decreased 60% in group 2, respectively. CONCLUSIONS: Isoconcentration nomogram was useful tool to control the expected concentration of fentanyl during TIVA and postoperative pain control using fentanyl IV-PCA.

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.

Reactive human mesothelial cells were examined by immunocytochemical stain with intermediate fiiaments (cytokeratin [CK1, CK7, CK8, CK18, CD19], vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen (CEA), MHC class II antigen (HLA-DR), LeuM-1 (CD15), alpha1-antitrypsin(ACT), alpha1-antichymotrypsin(ACMT), CD68(KP-1) and FcyRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients transudates. The results obtained are as follows. 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cytokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative r CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes/histiocytes(CD11b, CD14, CD16, CD68, lysozyme and alpha1-antitrypsin and alpha1-antichymotrypsin) were nonreactive in resting mesothelial cells, but lysozyme and alpha1-antitrypsin were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothellal cells show a newly aberrant expression of the vimentin and carcino-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothellal cells should be further evaluated.

BACKGROUND: Because of wide individual variations in response to sedative and the level of sedation desired by different patients, inadequate sedation is frequent during surgery. Patient-controlled sedation is a logical extension of patient-controlled analgesia to find and maintain their own steady-state of sedation by self-administration of sedatives during surgery. The purpose of this study was to evaluate the feasibility of patient-controlled sedation compared with anesthesiologist-controlled sedation during surgical spinal anesthesia. METHODS: Unpremedicated forty adult patients who received spinal anesthesia for lower extremity surgery were randomly allocated into two groups (n=20 for each group). After selection of target state of sedation according to sedation scale, patient-controlled sedation (PCS) group self-administered 0.5 mg (1 ml) intravenous midazolam in increments using a Walkmed PCA infusor and anesthesiologist- controlled sedation (ACS) group administered by the anesthesiologist as the same manner to achieve previously selected sedation state. Sedation score, vital signs, SpO2 were checked 5, 10, 20, 30, 40min after start of drug injection. RESULTS: The sedation scores patient desired were 4.4 +/- 0.8 in PCS group and 4.3 +/- 0.7 in ACS group. These scores were achieved 20min after start of injection in PCS group and 40 min in ACS grou p (p<0.05). Degree of satisfaction was higher in PCS group compared with ACS group (1.5 +/- 0.6 vs 2.1 +/- 0.8, p<0.05). No complications were detected in two groups. CONCLUSIONS: PCS using midazolam was better than ACS in terms of early achievement of sedation state patient desired and degree of satisfaction.
