Induction of general anesthesia with tracheal intubation is routine procedure but causes significant tarchycardia and hypertension. Many approaches have been tried to attenuate these circulatory response. The effects of small dose fentanyl on arterial pressure and heart rate increase during intubation were studied in 40 normotensive patients, who were randomly allocated to two groups, receiving saline (Control group) or fentanyl 2ug/kg (Fentanyl group), in a double blind fashion during anesthetic induction with thiopental 5mg/kg. Systolic, diastolic, mean arterial pressure and heart rate were measured and rate pressure product was calculated. All parameters were significantly different between two groups (p<0,05) and control group was significant increase in blood pressure and heart rate compared with pre-induction value but fentanyl group was relatively small changes of blood pressure and heart rate (p<0.01). After tracheal intubation, incresed blood pressure was returned to pre-induction value within two to three minutes in fentanyl group but heart rate was not returned pre-induction value within 5 minutes. Dose of fentanyl that are low enough to cause any side effects of drug itself, no notable side effects were observed during study and recovery.

The serum cholinesterase level is influenced by a variety of disease states, especially in pregnancy as is well established now, although the reasons for the fall in the enzyme in certain conditions and its clinical significance are less clear. This known decrease in plasma cholinesterase activity could lead to the conclusion that the duration of paralysis from succinylcholine will be prolonged in pregnant patients. The purposes of this study were to evaluate the serum cholinesterase activity in nonpregnant women of the child-bearing age group and pregnant women and to evaluate the changes of serum cholinesterase following succinylcholine administration. The results were as follows: 1) The mean value of serum cholinesterase in 60 nonpregnant women of the child-bearing age group was 992.29-1,112.27 U/L. 2) The mean value of serum cholinesterase in 60 pregnant women was 769.40-826-27 U/L. 3) Pregnant women had a diminution of serum cholinesterase activity compared with nonpregnant women of the child-bearing age group, and this diminution was statistically very significant (p<0.01). 4) In Cesarean section patients treated with succinylcholine, there was further diminution of serum cholinesterase activity (P<0.01). With the above results, the possible clinical importance of marked diminution of a serum cholinesterase activity in pregnant women is outlined.

Anesthesiologists should have close relationship with muscle relaxants and their reversals in clinical practice. Nowadays, the nondepolarizaing blocker is interested more than the depolarizing blocker and its reversibility. The composition of atropine, neostigmine and glycopyrrolate has been investigated for many years in korea. This study was undertaken to investigate the effects of glycopyrrolate(7ug/kg) and pyridostigmine(200ug/kg) mixture for pancuronium reversal on the heart rate and the blood pressure during halothane and enflurane anesthesia. The results were as follows: 1) In the halothane group: significantly increased mean blood pressure as compared with the enflurane group at 2,4,6 minutes and no significant difference was found after 8 minutes. 2) In the halothane group: significantly increased pulse rate at 2 and 4 minutes and decreased after 12 minutes. 3) In the Enflurane group: significantly increased pulse rate at 2,4 and 6 minutes and no increase after 8 minutes. 4) In the halothane group: significantly decreased pulse rate as compared with the enflurane group after 6 minutes and thereafter. 6) There was no significant arrhythmia but 2 cases of the bradycardia were observed in the halothane group at 14 minutes which were treated by atropine.

BACKGROUND: The Acute Physiology and Chronic Health Evaluation (APACHE) II model has been widely used in Korea. However, there have been few studies on the APACHE IV model in Korean intensive care units (ICUs). The aim of this study was to compare the ability of APACHE IV and APACHE II in predicting hospital mortality, and to investigate the ability of APACHE IV as a critical care triage criterion. METHODS: The study was designed as a prospective cohort study. Measurements of discrimination and calibration were performed using the area under the receiver operating characteristic curve (AUROC) and the Hosmer-Lemeshow goodness-of-fit test respectively. We also calculated the standardized mortality ratio (SMR). RESULTS: The APACHE IV score, the Charlson Comorbidity index (CCI) score, acute respiratory distress syndrome, and unplanned ICU admissions were independently associated with hospital mortality. The calibration, discrimination, and SMR of APACHE IV were good (H = 7.67, P = 0.465; C = 3.42, P = 0.905; AUROC = 0.759; SMR = 1.00). However, the explanatory power of an APACHE IV score >93 alone on hospital mortality was low at 44.1%. The explanatory power was increased to 53.8% when the hospital mortality was predicted using a model that considers APACHE IV >93 scores, medical admission, and risk factors for CCI >3 coincidentally. However, the discriminative ability of the prediction model was unsatisfactory (C index <0.70). CONCLUSIONS: The APACHE IV presented good discrimination, calibration, and SMR for hospital mortality.

OBJECTIVE: To investigate the effect of pulsed radiofrequency (PRF) treatment on pain and balance in patients with lumbosacral radiculopathy.METHOD: This study included twenty-five patients who were diagnosed with chronic lumbosacral radiculopathy. They underwent PRF treatment in prone position under the fluoroscopic guidance. The effect of PRF was measured by the visual analog score (VAS). Patient ability to balance was evaluated by using the Tetra-ataxiometric posturography (Tetrax).RESULTS: After PRF all patients showed improvement in pain as measured by VAS (p < 0.001) and none of the patients reported any side effects. The posturographic balance, which was evaluated by Tetrax showed no significant decline after PRF treatment. The weight distribution index (WDI) with eyes open before treatment was 5.43 ± 2.88 and after treatment was 5.37 ± 2.65 (p=0.917). The mean stability index (SI) with eyes open before treatment was 16.52 ± 6.05 and after treatment was 16.61 ± 4.85 (p=0.906). The mean WDI with eyes closed before treatment was 5.66 ± 2.81 and after treatment was 5.16 ± 2.70 (p=0.470). Finally, the mean SI with eyes closed before was 25.88 ± 9.88 and after treatment was 25.99 ± 12.30 (p=0.962).CONCLUSION: The results suggest that PRF has an effect on pain in patients with chronic lumbosacral radiculopathy. The patients did not experience adverse effects, such as hypoesthesia, dysesthesia and decreased proprioception after PRF, and there were no significant declines in balance.

BACKGROUND: Iron is essential for life, but iron overload state cause potentially fatal health risk. There is growing evidence that only mildly increased amounts of hepatic iron can be damaging, particulary if combined with other hepatotoxic factors such as alcoholic or chronic viral hepatits B,C. The aim of this study was to assess the serum iron status of patients with various forms of hepatitis and cirrhosis of liver and to determine the correlation between the degree of hepatocyte damage (expressed as ALT activity) and status of serum iron parameters. METHODS: Our research involved 107 patients (69 male ranging in age from 27-67 and 38 female ranging in age from 32-62) diagnosed with chronic viral hepatitis B or type C, alcoholic hepatitis or cirrhosis of the liver. Serum iron parameters such as serum iron, ferritin, TIBC, and aminotransferase measured as necroinflammatory activity in Chronic hepatitis. RESULTS: There was no difference s-iron level between chronic hepatitis and cirrhosis but, significantly higher in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis respectively. s-Ferritin level was significantly higher in cirrhosis than hepatits group, and more higher in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis respectively. In chronic hepatitis groups, there are significant correlation between ALT and s-ferritin level regardness of etiology. CONCLUSION: Serum iron overload state was prominent in alcoholic hepatitis and cirrhosis than viral hepatitis and cirrhosis. High serum ferritin level can predict hepatocyte damage in chronic hepatitis.

OBJECTIVE: Greater occipital nerve block (GONB) is a widely accepted treatment of primary headaches. Two ultrasound (US)-guided blockade techniques exist: 1) the classical distal nerve block technique performed medial to the occipital artery at the superior nuchal line, and 2) the new proximal nerve block technique performed at the obliquus capitis inferior muscle at the level of C2. Our study aim was to perform a head-to-head comparative study of these two US-guided techniques.METHOD: Forty-nine patients with primary headache treated in our university hospital were recruited. Patients were randomized into two groups of the classical nerve block and the new proximal nerve block techniques. The headache questionnaire was made to assess the intensity of the pain of headache attacks, number of days they experience headache, duration of headache, and amount of pain medication they consumed.RESULTS: In both groups, a decrease in the severity and frequency of the headache was observed. There was no measurable difference in outcome between the two groups.CONCLUSION: Our study showed that the classic and new proximal techniques are equally effective in decreasing the headache severity and frequency.

Purpose:
Alpha-fetoprotein (AFP) is a prognostic marker for hepatocellular carcinoma (HCC). We investigated the prognostic value of AFP levels in patients who achieved complete response (CR) to transarterial chemoembolization (TACE) for HCC.
Materials and Methods:
Between 2005 and 2018, 890 patients with HCC who achieved a CR to TACE were recruited. An AFP responder was defined as a patient who showed elevated levels of AFP (>10 ng/mL) during TACE, but showed normalization or a >50% reduction in AFP levels after achieving a CR.
Results:
Among the recruited patients, 569 (63.9%) with naïve HCC and 321 (36.1%) with recurrent HCC after complete resection were treated. Before TACE, 305 (34.3%) patients had multiple tumors, 219 (24.6%) had a maximal tumor size >3 cm, and 22 (2.5%) had portal vein tumor thrombosis. The median AFP level after achieving a CR was 6.36 ng/mL. After a CR, 473 (53.1%) patients experienced recurrence, and 417 (46.9%) died [median progression-free survival (PFS) and overall survival (OS) of 16.3 and 62.8 months, respectively]. High AFP levels at CR (>20 ng/mL) were independently associated with a shorter PFS [hazard ratio (HR)=1.403] and OS (HR=1.284), together with tumor multiplicity at TACE (HR=1.518 and 1.666, respectively). AFP non-responders at CR (76.2%, n=359 of 471) showed a shorter PFS (median 10.5 months vs. 15.5 months, HR=1.375) and OS (median 41.4 months vs. 61.8 months, HR=1.424) than AFP responders (all p=0.001).
Conclusion
High AFP levels and AFP non-responders were independently associated with poor outcomes after TACE. AFP holds clinical implications for detailed risk stratification upon achieving a CR after TACE.
