목 적 : 뇌수막염은 뇌와 척수를 둘러싸는 막의 염증으로 여름과 가을에 소아들에 호발하여 합병증이 발생하면 신경학적 후유증을 야기할 수 있는 질환이다. 뇌수막염의 합병증으로 뇌부종이 발생한 경우 증상치료로서 mannitol과 고장성 식염수가 삼투성 이뇨치료로 이용되어진다. 고장성 식염수는 다양한 농도와 투여방법이 있을 수 있는데 본 연구는 고장성 식염수의 가장 효과적이고 안전한 투여 형태에 대해 고찰하였다. 방 법 : 2002년 1월부터 2005년 10월까지 부산의료원 소아과에 입원하였던 뇌수막염환아 283명중 뇌부종이 발생했던 42명의 환아를 대상으로 하였다. 20% mannitol과 4가지 형태의 고장성 식염수로 치료하였던 5가지 투여군을 분석하였다. 증상과 징후의 호전유무, 뇌압측정치, 뇌혈류속도 측정치, 검사소견으로 효과적인 투여형태에 대해 통계적 분석을 하였다. 결 과 : 1) 환아의 평균연령은 5.34세이었으며 남녀 비율은 남아가 22명이고 여아는 20명이었다. 주된 임상양상은 발열(97%), 두통(92%), 구토(71%), 경련(47%), 기면(35%), 경부강직(35%), 복통(35%), 기침(35%), 유두부종(35%), 보챔(28%), 수두증(11%) 순으로 나타났다. 2) 증상 및 징후의 호전유무는 치료 4일째 24명이 상기증상 및 징후의 50%이상의 호전을 나타내었다. 3% 고장성 식염수 농축괴와 3% 고장성 식염수 연속적 농축괴 그리고 7.5% 고장성 식염수 연속적 농축괴의 방법이 효과적인 것으로 분석되었다(P<0.05). 3) 뇌압측정치는 5가지 방법모두 뇌압하강효과가 있는 것으로 나타났다. 3% 고장성 식염수 연속적 농축괴 주입이 뇌압하강치가 1.86 kPa로서 가장 좋은 기록이었지만 통계학적 의미는 없었다(P=0.31). 4) Transcranial doppler에 의한 MFV와 PI 측정에서는 5가지 방법 모두 MFV도의 상승과 PI 하강을 보여주었다. PI와 MFV 상에서는 5가지 방법에서 치료효과의 차이가 없는 것으로 분석할 수 있었다(P=0.59, P=0.99). 5) 치료기간동안 다양한 검사소견을 비교할 수 있는데 나트륨, 염소, 수소이온농도, 젖산, 몰삼투압농도, 칼슘은 차이가 날 수 있는 것으로 관찰되었고(P<0.05), 칼륨, 혈색소, 중탄산염, 염기 과다는 차이가 없는 것으로 분석되었다. 나트륨, 염소, 몰 삼투압농도는 약간 상승되었고 수소이온농도, 젖산, 칼슘은 약간 하강하였으나 큰 변화는 없었다. 결 론 : 뇌수막염에서 뇌압상승, 뇌부종이 발생한 환아의 증상치료로서 고장성 식염수가 다양한 농도와 투입방법이 고려되어 질 수 있다. 본 연구의 결과로는 3% 고장성 식염수 연속적 농축괴의 투여방법이 가장 우수해 보이나 무작위 추출이 아니며 여러 가지 결과를 종합할 때 가장 우수하다고 하기에는 무리가 있었다. 향후 보다 더 많은 집단을 대상으로 한 무작위 추출의 다양하고 종합적인 연구가 필요할 것으로 사료된다.

Hemodialysis(HD)-associated hypotension is a frequent complication, but it is difficult to manage. Until now, several maneuvers have been tried to prevent the HD-associated hypotension. Of these, the sodium content of dialysate was regarded as an important factor for maintaining blood pressure during HD. In this study, we evaluated the effect of hypertonic dialysate on blood pressure, interdialytic weight gain and the incidence of thirst. The study was done for 6 weeks successively with 3 different groups. Each patient was dialysed with 3 different dialysates for 2 weeks: Group I(Conventional HD: sodium concentration: 137 mEq/L), Group II(Hypertonic HD: 147 mEq/L) and Group III (Sequential HD: from 147 to 140 mEq/L). Hemodynamic parameters(blood pressure, pulse rate and ultrafiltration rate), biochemical parameters(hematocrits, blood urea nitrogen, creatinine, osmolality, sodium, potassium, chloride, fasting blood sugar) and complications (interdialytic weight gain & thirsty sensation) were compared among 3 groups. The results were as follows: 1. Decline of systolic blood pressure and diastolic blood pressure at the time of a 3 hour check during hemodialysis was lower in the Group II than Group I and III (p=0.002; p=0.012). and decline of diastolic blood pressure at the time of a 4 hour check during hemodialysis was lower in the Group II and III than Group I (p=0.04). 2. Incidence of hypotensive episodes during dialysis was significantly lower in Group II than group I (p=0.0287). 3. The ultrafiltration in Group III at the time of 1 hour, 2 hour and 3 hour check during hemodialysis was higher than that in Group I and II at the time of 1 hour, 2 hour and 3 hour check during hemodialysis respectively (p=0.0001; p=0.0001; p=0.0004). 4. Interdialytic weight gain was higher in Group I($3.1{\pm}0.8$) than Group I($2.8{\pm}0.8$) and III ($2.9{\pm}0.9$) (p=0.0422). 5. Hematologic and biochemical results were not significantly different among 3 Groups. 6. Frequency of thirst was different in Group I, II and III, $0.05{\pm}0.12$, $0.41{\pm}0.24$and $0.22{\pm}0.29$ respectively (p=0.0259). The results suggest that hypertonic HD was effective in preventing HD-associated hypotension but interdialytic weight gain and thirst sensations were increased as compared with a conventional method. In this situation, sequential HD seems to be an alternative method to minimizes the side effect of hypertonic HD.

In the present study, an effort was directed to elucidate the effect of osmolality on the absorption of ethanol in rabbits. A single dose of 13.67 ml(2. 16 gm ethanol/kg BW) of hypo-, iso-hyphen and hypertonic ethanol per kg BW was administered into the stomach to albino rabbits and the experiment was performed at 30 th, 60 th and 120 th minute. The blood ethanol level was determined by the method of Williams et al, and hematocrit(Hct) was determined by the conventional Hct centrifuge and reader. The results are summarized as follow. The blood ethanol level showed the highest value at 60 min after the ethanol ingestion in the hypo- and isotonic groups, $171.3{\pm}13.3\;mg%$ and $204.5{\pm}23.0\;mg%$, respectively, but in the hypertonic group, the highest value was observed at 120min after the ingestion. The absorption rate of ethanol between 0 to 30 min after the ingestion of hypo- and isotonic ethanol was $88.54{\pm}12.04$ and $94.73{\pm}8.33\;mg/min$, respectively, but a decreased value of $44.72{\pm}6.69\;mg/min$ was noted after hypertonic ethanol ingestion comparing with hypo- and isotonic groups, The Hct value after hypo- and isotonic ethanol ingestion was decreased at 30 min but returned to the control level at 120 min. In contrast with hypo- and isotonic ethanol ingestion, hypertonic ethanol ingestion produced an increase of the Hct value at 30 min and returned to the control level at 120 min. The heart rate was increased but the respiratory rate was decreased after ethanol ingestion regardless of the osmolality.

Background: Mycobacterial identification in active pulmonary tuberculosis (APTB) is confirmative, even though successful rates using self-expectorated sputum are limited. Sputum specimens collected by hypertonic saline nebulization showed higher bacteriologic diagnostic sensitivities over those of self-expectoration, mostly studied in smear-negative or sputum-scarce patients. The efficacy of induced sputum was rarely assessed in real clinical settings. Methods: A prospective randomized case-control study was performed in one hospital. The subjects highly suspicious of APTB were asked to provide 3 pairs of sputum specimens in 3 consecutive days. The first pairs of the specimens were obtained either by self-expectoration (ES) from the next day of the visit or sputum induction with 7% saline nebulization in clinic (SI), and the other specimens were collected in the same way. The samples were tested in microscopy, culture, and polymerase chain reaction (PCR). The outcomes of the bacteriological diagnosis were compared. Results: Seventy six patients were assigned to either ES (38 subjects, median age of 51, 65.8% male) or SI (38 subjects, median age of 55, 52.6% male). APTB was clinically confirmed in 51 patients (70.8%), 27 in ES and 24 in SI. Among the APTB, more adequate specimens were collected from SI (41/65, 63.1%) than ES (34/80, 42.5%) (p=0.01). Bacteriological confirmation was achieved in 14 (58.3%) patients in SI, and 13 (48.1%) in ES (p=0.46). In the same-day bacteriological diagnosis with microscopy and PCR, there were positive results for 9 patients (37.5%) in SI and 7 patients (25.9%) in ES (p=0.37). Conclusion: Sputum induction improves sputum specimen adequacy. It may be useful for the same-day bacteriological diagnosis with microscopic examination and PCR.

Objectives: The main purpose of this study was to quantify the risk of mortality linked to various regimens of hypertonic peritoneal dialysis (PD) solution. Methods: A retrospective cohort study of patients using home-based PD was carried out. The prescribed regimen of glucose-based PD solution for all patients, determined on the basis of their individual conditions, was extracted from their medical chart records. The primary outcome was death. The treatment regimens were categorized into 3 groups according to the type of PD solution used: original PD (1.5% glucose), shuffle PD (1.5 and 2.5% glucose), and serialized PD (2.5 and 4.5% glucose). Multivariate analysis (using the Weibull model) was applied to comprehensively examine survival probabilities related to the explanatory variable, while adjusting for other potential confounders. Results: Of 300 consecutive patients, 38% died over a median follow-up time of 30 months (interquartile range: 15-46 months). Multivariate analysis showed that a treatment regimen with continued higher-strength PD solution (serialized PD) resulted in a lower survival rate than when the conventional strength solution was used (adjusted hazard ratio, 2.6; 95% confidence interval, 1.6 to 4.6, p<0.01). Five interrelated risk factors (age, length of time on PD, hemoglobin levels, albumin levels, and oliguria) were significant predictors contributing to the outcome. Conclusions: Frequent exposure to high levels of glucose PD solution significantly contributed to a 2-fold higher rate of death, especially when hypertonic glucose was prescribed continuously.

Background: Radiofrequency ablation (RFA) is the most widely used and studied method internationally for the local treatment of liver tumors. However, the extension of coagulation necrosis in one RFA procedure is limited and incomplete coverage of the damaged area can lead to a high local recurrence rate. Objective: In this study, we compared the effects of different solutions in enhancing hepatic radiofrequency by establishing a rabbit VX2 liver cancer model. We also determined the optimal solution to maximise effects on the extent of RFA-induced coagulation necrosis. Methods: Thirty VX2 tumor rabbits were randomly assigned to five groups: group A, RFA alone; group B, RFA with anhydrous ethanol injection; group C, RFA with 5% hypertonic saline injection; group D, RFA with lidocaine injection; and group E, RFA with a mixed solution. Routine ultrasound examinations and contrast-enhanced ultrasound (CEUS) of the ablation areas were performed after RFA. Then, we measured the major axis and transverse diameter and compared the areas of coagulation necrosis induced by RFA. Results: The mean ablation area range increased in groups B, C and especially E, and the scopes were greater compared with group A. Preoperative application of anhydrous ethanol, hypertonic saline, lidocaine and the mixed solution (groups B, C, D and E, respectively) resulted in larger coagulation necrosis areas than in group A (p<0.05). Among the groups, the coagulation necrosis areas in group E was largest, and the difference was statistically significant compared with other groups (p<0.05). Pathological findings were consistent with imaging results. Conclusions: A mixture of dehydrated alcohol, hypertonic saline and lidocaine injected with RFA increases the extent of coagulation necrosis in the liver with a single application, and the mixed solution is more effective than any other injection alone.

Background: Hypertonic saline (HS) injections for decompressive neuroplasty (DN) can cause pain. We assessed whether a continuous infusion of HS through an infusion pump would reduce injection-related pain compared with repeated bolus administrations. Methods: Fifty patients scheduled for DN were randomized to either the bolus injection or the continuous infusion group. After appropriately placing the epidural catheter, 4 mL of 5% NaCl was injected as four boluses of 1 mL each at 15-minute intervals or infused over 1 hour using an infusion pump. The severity of pain induced by HS injection, as measured by the 11-point numerical rating scale (NRS), was the primary outcome. The severity of low back or lower extremity pain, as measured by the 11-point NRS and Oswestry Disability Index (ODI), 3 months following the procedure, was the secondary outcome. Results: Data from 21 patients in the bolus group and 23 in the continuous infusion group were analyzed. No statistically significant difference in injection-related pain was identified between the two groups during the initial HS administration (P = 0.846). However, there was a statistically significant reduction in injection-related pain in the continuous infusion group compared to the bolus injection group from the second assessment onwards (P = 0.001, < 0.001, and < 0.001, respectively). No significant between-group differences in the NRS and ODI scores 3 months post-procedure were noted (P = 0.614 and 0.949, respectively). Conclusions: Our study suggests that administering HS through a continuous infusion is a useful modality for reducing HS injection-related pain during DN.
