Purpose: The purpose of this study was to examine the effect of nebulizer therapy with normal saline on thirst and sore throat among postoperative patients. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used with 50 participants. The experimental group received nebulizer therapy with normal saline every two hours for 10 minutes three times and wet gauze (n= 25), and the control group received only wet gauze (n= 25). Data were collected using the Numeral Rating Scale for Thirst and Sore Throat. Measurements were calculated before applying nebulizer therapy and total five times for 12 hours after treatment. Data were analyzed using the repeated measured ANOVA. Results: Thirst for the experimental group using the nebulizer therapy with normal saline improved more than for the control group (F= 3.06, p= .043). Sore throat was not significantly different between the two groups (F= 0.63, p= .565). Conclusion: Study results indicate that using nebulizer therapy with normal saline can reduced thirst for postoperative patients. So nurses can apply nebulizer therapy with normal saline to reduce thirst and to improve comfort for postoperative patients.

It has been contributed to public health that the hospital has multiplied in the aspect of number and has been a large size with development of modern medical science, meanwhile the problem of hospital infection is coming out seriously. Respiratory hospital infection among hospital infections develops, very commonly from patients having taken the operation of intubation or tracheostomy, which results from a big factor that the infection developed from medical appliances used for respiration aids, contamination of solution and infection of medical staff. This study is separated into four steps-the time to use normal saline and distillation water for storaging catheter which are the cause of the infection of solution to store distillation water and catheter, not to say the catheter used when the patient who should get tracheostomy operation takes suction. The purpose of this study is to offer the basic data which are needed to check contamination degree as time goes by and nurse intervention and grope for a new nursing intervention. The target of this study is hospitalized 1D an intensive care unit having 700 sickbeds which is located in IKSAN city and it targeted patients before 7 days passed after an operaion of a tracheostormy. Materials collected were analyzed by SPSS PC+ figures program. The result of this study were as follows ; 1. The gradual contamination levels of the normal saline used In suction are showing that colony increase in proportion to the length of time. 2. while colony increases in normal saline with the lapse of time. distillation water mixed with 5cc of potadine did not show any sign of the formation of colony from its preparation until it was used for 8 hours. 3. Such variables as the period of intubation insertion. the length of hospitalization in I.C.U. the age and the level of contamination of normal saline have no inter-relationship. Therefore. as the length of normal saline used In suction. the contamination level increases with the excelleration of the contamination speed. 4. Regarding the number of suction and the contamination level of the normal saline. We can observe correlation contamination level in the 3 step of suction(mean value:13.4) and the saline which was used for one hours(r=0.702. P=0.00l). four hours(r=0.694. P=0.00l). eight hours(r=0.488. P=0.029). Further we can observe contamination in the 4 step of suction (mean value: 17 .8) well as saline used for eight hours; [for one hours (r=0.64l. P=0.002). four hours (r=0.670. P=0.00l). eight hours (r=0.57 4. P=0.008)]. Thesedays clinics use normal saline by changing it. three times a day. however. the timing of saline change and the current suction methoed should be changed given the one hour used normal saline contamination number 79.850. Regarding the number of suction and the contamination lend of the normal saline.

The purpose of this study is to observe the corrosion characteristics of five dental amalgams(CAULK FINE CUT, OPTALLOY II, DISPERSALLOY, TYTIN, and VALIANT) in the solutions with fluoride compound through the anodic polarization curve obtained by using a potentiostat. After each amalgam alloy and Hg being triturated, the triturated mass was inserted into the cylindrical metal mold, and condensed by hydraulic pressure(160 kg/$cm^2$). Each specimen was removed from the metal mold. Specimens were polished with the silicone carbide grinding paper 24 hours after condensation and stored at room temperature for 1 week. The anodic polarization curves were employed to compare the corrosion behaviours of the amalgams in 0.9 % saline solution and in the saline solutions with 2.2 ppm, 0.05 %, 2 % NaF, and 8 % $SnF_2$ at $37^{\circ}C$ with 3-electrode potentiostat. After the immersion of specimen in electrolyte for 30 minutes, the potential scan was begun. The potential scan range was -1500m V to + 800m V(vs. S.C.E.) in the working electrode and the scan rate was 50 mV/sec. The results were as follows, 1. The corrosion potential, the potential of anodic current peak, and transpassive potential in the saline solutions with NaF shifted to lower direction than those in normal saline solution, and the current density in the saline solutions with NaF was higher than that in normal saline solution. The differences were increased as the concentrations of NaF became higher. 2. The corrosion potential and transpassive potential in the saline solution with $SnF_2$ shifted to higher direction than those in normal saline solution, and the current density in the saline solution with $SnF_2$ was higher than that in normal saline solution after the corrosion potential. The anodic polarization curves in the saline solution with $SnF_2$ had no outstanding anodic current peak. 3. The corrosion potentials for high-copper amalgams were much higher than those for CAULK FINE CUT and OPTALLOY II in normal saline solution, but, as the concentrations of fluoride compound became higher, the differences in corrosion potentials between them were decreased. The corrosion potentials had the similarity in the saline solution with 2% NaF or 8% $SnF_2$. 4. The current density for TYTIN was the lowest among the others in normal saline solution and in the saline solution with 2.2 ppm or 0.05 % NaF. 5. There was no significant difference in current density between Pd-enriched VALIANT and other high-copper amalgams.

Purpose: Regarding the respiratory function of patients with an artificial airway, this study compared the effects between normal saline with chest vibration and normal saline with expectorant mixture, administered before endotracheal suction. Methods: The study was conducted in the ICUs of one university hospital located in Incheon. The experimental group I received normal saline with chest vibration administered before endotracheal suction while the experimental group II received normal saline with expectorant mixture administered before endotracheal suction. For respiratory function, $PaO_2$, $PaCO_2$, and $O_2$ saturation were measured by ABGA at 3 minutes after endotracheal suction for both pre-test and post-test. Results: The two groups were not different significantly regarding $PaO_2$ level and $O_2$ saturation after the treatments, while, the experimental group II had lower $PaCO_2$ level than the experimental group I after the treatments (t = 2.075, p = .042). For experimental group II, post-test score of $PaCO_2$ level was significantly lower than that of the pre-test score (t = 1.842, p = .075). Conclusion: The administration of normal saline with expectorant mixture before endotracheal suction reduced $PaCO_2$ level and improved the respiratory function.

Background: Intravenous fluid therapy is one of the most common interventions in critically ill patients. Normal saline is frequently used, but there have been some concerns about hyperchloremia. Due to closer to plasma composition, crystalloids have been used as alternatives to normal saline. However, the optimal choice of resuscitative fluids remains controversial. Methods: MEDLINE, EMBASE, and CENTRAL were comprehensively searched until July 2021 to compare balanced crystalloids with normal saline in critically ill patients with the risk factors for multiple organ dysfunction syndromes (MODS).The primary endpoint was composite mortality. Secondary outcomes were acute kidney injury (AKI)/acute renal failure (ARF), and new receipt of renal replacement therapy (RRT). Results: A total of 1,240 studies were searched, and finally, 8 randomized controlled trials and 5 cohort studies were included. In the meta-analysis of composite mortality of 30,710 patients, balanced crystalloids compared to normal saline were significantly associated with reduced mortality (OR 0.80, 95% CI 0.68-0.95). In AKI/ARF, balanced crystalloids had a lower risk than normal saline (OR 0.91, 95% CI 0.84-0.99). There was no difference between balanced crystalloids and normal saline in risk of new receipt of RRT (OR 0.91, 95% CI 0.80-1.04). Conclusion: In fluid resuscitation for patients at high risk of MODS, the use of balanced crystalloids showed a significantly lower incidence of mortality compared to normal saline.

고농도의 산소를 흡입하는 경우에 자기공명영상의 FLAIR(fluid attenuated inversion-recovery, FLAIR) 영상에서 뇌척수액에서 신호가 억제되지 않고 고신호로 나타나는 경우가 있다는 보고가 있었다. 본 연구는 아가 젤로 고정한 팬텀을 제작하여 산소를 주입한 생리식염수와 조영제를 희석한 생리식염수의 신호를 FLAIR 기법의 반전시간(TI : inversion time)을 변화하여 영상을 획득하고, 분석하여 기초자료를 마련 하고자 하였다. 부산 P병원의 Philips Achieva MR 3.0T를 이용한 결과에서 자기공명영상의 FLAIR 기법에서 산소가 주입된 생리식염수의 신호 대 잡음비(signal to noise ratio)는 산소가 주입되지 않은 생리식염수 보다 증가되었다. 하지만 희석된 조영제보다는 높지 않았다. 반전시간 1,800ms에서는 산소에 의한 신호 증강이 없는 영상을 획득할 수 있었다. 산소가 주입된 생리식염수와 조영제의 대조도 대 잡음비(contrast to noise ratio)에서도 임상에서 주로 사용하는 반전시간 2,800ms보다 1,800ms에서 높게 증가되었다. 본 실험의 결과가 자기공명영상의 FLAIR 기법에서 산소 주입에 따른 뇌척수액의 신호 변화 연구에 기초자료가 될 수 있을 것으로 사료된다.

이 연구는 자기공명영상검사 시 조영제 주입용으로 사용되는 자동주입기에서 조영제 역류에 의한 생리식염수의 오탁 현상을 방지할 수 있는 대안을 모색하고자 하였다. 연구방법은 실린지 내에서 조영제 역류를 차단할 대안으로 밸브를 자체 제작한 다음, 임상적용의 유용성을 알아보기 위해 생리식염수의 상태를 세 그룹으로 나누고 조영제 주입을 실험하여 각각 채취한 생리식염수의 지방소거 T1 강조영상으로 신호강도를 비교하였다. 연구결과, 그룹 1의 조영제 주입 전 생리식염수와 그룹 3의 역류방지용 밸브를 적용한 조영제 주입 후 생리식염수가 통계적으로 유의한 차이가 없었다(p>0.05). 이는 자체 제작한 역류방지용 밸브가 조영제 주입 시 생리식염수로 역류하는 조영제를 완벽히 차단한 것으로 분석된다. 결론적으로 조영제 자동주입기를 활용한 자기공명영상 동적검사 시 본 연구에서 제시한 역류방지밸브를 적용한다면 조영제 역류로 인한 생리식염수의 오탁 현상을 예방할 수 있으리라 본다.

Purpose: The purpose of this study was to compare and analyze the effects of gargling using normal saline or essential oil on oral bacterial colonization of the subjects who did transoral endotracheal intubation for general anesthesia. Methods: A repeated measures, non-equivalent control group pretest-posttest design was used in this study. The subjects of the study included 58 people; the gargling group with normal saline (n=19); the gargling group with essential oil (n=20); and the control group (n=19). Data were collected from University hospitals in a Korean province from August 13-31, 2012. The collected data were analyzed with $X^2$-test, t-test, ANOVA and Scheff$\acute{e}$ test using SPSS 19.0. Results: Although statistically significant differences among the three groups did not appear in the change of the aerobic bacterial colony before and after the experiments, the aerobic bacterial colony of the gargling group with normal saline ($71.58{\pm}143.39$) and the group with essential oil ($6.95{\pm}332.07$) have increased less compared to the control group ($145.42{\pm}385.01$). The change of the anaerobic bacterial colony before and after the experiments, the control group was ($167.58{\pm}483.58$) and the gargling group with essential oil was ($169.70{\pm}291.60$) and increased, while the gargling group with normal saline ($-42{\pm}331.09$) reduced, but statistically significant differences have not appeared. Conclusion: These findings indicated that oral gargling with normal saline is effective in reducing anaerobic bacterial colonization.

The purpose of this study was to investigate the effects of a protein-free, standardized dialysate/ultrafiltrate (HD) derivatives from calf blood (Solcoseryl$^{(R)}$) for second-intention full-thickness skin wound healing in dogs. Three $2{\times}2cm$ area-matched full-thickness skin wounds were created bilaterally on the dorsolateral aspect of the trunk of nine dogs. In each dog, two wounds were treated with HD, cemella asiatica extract (Centrasol$^{(R)}$) and normal saline, respectively. For six weeks, the wounds were evaluated grossly for contraction, epithelialization and healing and were examined histopathologically. In the first week of the wound healing period, HD stimulated wound contraction and healing more significantly than centasol and normal saline (p<0.05). Neutrophils were more increased in the HD-treated wounds than those in centasol or normal saline treated wounds. In the second week, HD stimulated epithelialization more significantly than centasol or normal saline (p<0.05), and neovascularization and granulation more increased in the HD-treated wounds than those in centasol and normal saline treated wounds. In conclusion, HD was the most effective on early wound contraction, epithelialization and healings among three experimental drugs in full-thickness skin wound.
