In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device. We report a successful airway conversion under the aid of both, a fiberoptic bronchoscope and a C-MAC video laryngoscope.

Purpose: The purpose of this pilot study was to investigate the effect of oral care using 0.1% chlorhexidine and tantum solution on oral status and incidence of oral pathogens among intubated ICU patients. Methods: The study subjects were 26 intubated patients of MICU in a university hospital. Oral care was provided with 0.1% chlorhexidine solution to the experimental group (n=12) and with tantum solution to the control group (n=14), 3 times a day for 6 days. After the intervention, the oral status of each subject was checked using structured method, and oral swab culture was done to count colonized bacterial pathogens. Results: The mean oral status score of experimental group was significantly higher than that of control group (U=42.50, p=.031). The mean incidence of oral pathogens in experimental group was smaller than that of control group, but the difference was not statistically significant. Conclusion: The oral care with 0.1% chlorhexidine solution is more effective than with tantum solution for improving oral status of intubated ICU patients. However, additional studies with larger sample size will be needed to figure out it's effects on the incidence of oral pathogens.

Purpose : This scoping review was designed to identify gaps in knowledge and guide future directions for clinical nursing practices and research on oral hygiene care for endotracheally intubated patients in Korean intensive care units. Methods : We conducted a scoping review using the methodological framework proposed by Arksey and O'Malley. PubMed, CINAHL, RISS, Science On, and DBpia databases were searched. Two reviewers independently selected the studies and extracted data. A total of 445 studies were identified, of which 17 were included in the final analysis. Results : No research has been conducted from 2021 to the present. A total of 12 instruments were utilized in 13 studies to assess the effectiveness of oral hygiene care. All studies investigating the effectiveness of oral hygiene care have consistently documented that chlorhexidine has the most significant effect. The frequency and time of oral hygiene care were each examined in one study. Conclusion : A research study is necessary to develop a measurement tool for assessing the effectiveness of oral hygiene care suitable for endotracheal intubated patients in intensive care units. Interventional studies should be conducted to determine the effects of chlorhexidine and the appropriate frequency and time of oral hygiene care. Thereafter, revision of domestic evidence-based clinical practice guidelines by integrating these results will be necessary.

Objectives: Exposure to fine dust (PM10) could contribute to the occurrence of cardiovascular disease or respiratory abnormalities. Since garlic is known to possess an anti-oxidative stress effect, the present study was performed to evaluate the effect of garlic intake on fine dust-mediated pulmonary toxicity. Methods: Rats were intratracheally instilled with fine dust at 15 mg/kg body weight (BW)/day for five days following five-day intragastric intubation of garlic at 0.7 or 1.4 g/kgBW/day, or 13.1 mg/kgBW/day S-allyl-cysteine (SAC) as a reference component in garlic. Blood and bronchoalveolar lavage fluid (BALF) were collected. Results: Deposit of fine dust was visually and histopathologically observed in the lungs. Body weight gain during the instillation period was significantly lowered in all the groups instilled with fine dust. Neutrophil numbers in blood were significantly elevated in the fine dust alone group, but this alteration was diminished in the groups administered with garlic. Levels of serum glutathione were lower in the rats instilled with fine dust alone, and this decrease in the glutathione level seems dose-dependently compensated among the groups administered with garlic. Similar findings were observed in the BALF with statistical significance. Typical pulmonary histopathological observation related with inflammation was demonstrated in the lungs of the rats exposed to fine dust alone, whereas such histopathologic findings were not improved in the groups administered with garlic. Conclusion: The present study suggests that garlic intake could alleviate fine dust-mediated pulmonary or systemic toxicities. Further investigation is necessary to delineate the mechanism of garlic-mediated effects on pulmonary function.

연구배경 : 최근 기계환기 중 기관지내시경술의 필요성이 증가하고 있으나, 시술 중 생리학적 변화나 안전성에 대한 연구가 부족한 상황이다. 이에 연구자들은 PEEP을 시술전과 동일하게 유지하면서 기관지내시경술을 시행하여 생리학적 변화 및 안전성에 대해 알아보고자 본 연구를 시행하였다. 방 법 : 2002년 6월부터 2002년 11월까지 삼성서울병원 내과계 중환자실에서 기계환기를 하면서 기관지내시경술을 시행했던 19명의 환자(남자 10명 여자 9명, 연령 중앙값 61.6세)를 대상으로 하였다. 기관지내시경술을 시행하기 전 100% 산소로 15분간 전산 소요법을 시켰으며 기관지내시경 시술 중 기계환기는 용적조절양식으로, 일회환기량 4 ml/kg, 호흡수 20회/분, 흡기 대 호기비 1:2로 환기하였으며 PEEP은 시술전과 동일하게 유지하였다. 시행 후 30분간 100% 산소를 유지하였다. 결 과 : 기관지내시경술 시행시간의 중앙값은 6분(범위 3-15분)이었다. 기관지내시경술을 시행하면서 호흡성 산증과 저환기, 최고기도압의 상승, 심박수의 증가, auto-PEEP의 발생을 보였다. 이들 변화는 기관지내시경 시술 후에 시술 이전의 상태로 되었다. 압력손상 및 혈압 감소 등의 심각한 합병증은 관찰되지 않았다 결 론 : 심각한 저산소증으로 높은 PEEP을 유지하고 있는 환자에게서 PEEP을 유지한 채로 기관지내시경술을 시행하여도 심각한 합병증은 관찰되지 않았다. 다만, 기관지내시경을 시행하는 동안 호흡성 산증 및 저환기를 보였고, 비록 가역적이지만 이러한 상태에서 환자의 노출을 최소화하기 위해서는 기관지내시경 시행시간을 최소화하여야 한다고 사료된다.
