Purpose: This study was conducted to assess the incidence and characteristics of pressure ulcer in relation to the type of equipment and supplies(EnS) in intensive care unit(ICU). Method: By using secondary data analysis and descriptive investigation, 29 patients of pressure ulcers caused by EnS were examined from January 2013 to December 2015, at the advanced general hospital located in Gyeongsangnam-do. The subjects were aged 19 years and above and had been in the ICU for more than 3 days. The data were analyzed using the SPSS WIN 23.0 with frequency, percentage, and mean and standard deviation. Result: The incidence of EnS-related pressure ulcers was 3.71%. The EnS-related causes for pressure ulcers were endotracheal tube(31.03%), restraint(20.69%), and neck brace(10.34%). The longest use of EnS was oxygen tube(29 days). EnS that were possibly causing pressure ulcer for one day were restraint(upper extremities), endotracheal tube(oral and face), and oxygen mask(ear and nose). Conclusion: This study has been limited to secondary data analysis that may result in missing records of pressure ulcers related to EnS in ICU. However, the analysis of this research is expected to contribute to the development of nursing interventions to clarify the guidelines for the prevention of pressure ulcers related to EnS in ICUs.

Nasotracheal intubation is commonly performed under general anesthesia in oral and maxillofacial surgery. For the convenience of surgery, nasal Ring-Adair-Elwyn (RAE) tubes are mainly used. Because the nasal RAE tubes were bent in an "L" shape, the insertion depth was limited. Particularly, it is necessary to accurately determine the appropriate depth of the RAE tubes in children. Several types of nasal RAE tubes are used in the medical market, which vary in material and length. We performed endotracheal intubation using a nasal RAE tube for double-jaw surgery, but air leakage persisted even when the air pressure in the cuff was increased. When checked with a laryngoscope, it was confirmed that the tube was pushed out, and the cuff was caught on the vocal cords, causing air leakage. Since inserting the tube deeply did not solve the problem, replacing it with a nasal RAE tube (Polar^TM, Preformed Tracheal Tube, Smith Medical, Inc., USA) did not cause air leakage; thus, we reported this case.

연구배경 : 기관내관의 삽관은 상기도 저항을 증가시켜 환자의 호흡 일을 증가시키는 것으로 알려져 있다. 그러나 기계 호흡으로부터 이탈 시 기관내관을 제거한 후에 오히려 호흡곤란이 증가하여 호흡 부전이 발생하기도 하므로 기관내관의 제거 후 호흡 일의 변화를 알아보고 이러한 호흡 일의 변화와 관련된 호흡역학적 지표들과의 상관 관계를 조사하고자 하였다. 방 법 : 기계 호흡 치료 후 기저 질환이 호전되어 호흡 부전으로부터 회복된 34명의 환자를 대상으로 기관내관 제거 직전, 제거 직후 및 48시간 까지 호흡 일과 호흡 역학적 지표들을 추적 관찰 하였다. 결 과 : 기관내관 제거 직전에 비해 직후 호흡 일이 감소한 환자는 33%(11/34), 변화 없는 환자는 41%(14/34), 증가한 환자는 26%(9/34)였다. 기관내관 제거 후 48시간 이내 기계 호흡의 보조나 다시 기관내관의 삽관을 받은 이탈 실패 환자는 3군(호흡 일이 증가된 군)에서는 44.4%(4.9), 2군(변화 없는 군)에서는 28.6%(4/14), 1군(감소된 군)에서는 9%(1/11)에서 발생하였다. 기관내관 제거 후 호흡 일의 변화는 주로 평균 기도 저항의 변화와 정 상관 관계를 보였다. 기관내관 제거 후 호흡 일이 증가한 환자군 중에서 48시간까지 호흡일이 측정된 3명의 환자에서 호흡 일과 평균 기도저항은 6시간까지 일률적으로 증가하였으며 24시간 후에는 감소되는 경향을 보였다. 결 론 : 기계 호흡 치료를 받은 환자들에서 기관내관 제거 직후 가역적인 호흡 일의 증가가 나타날 수 있으며 이는 주로 평균 기도 저항의 증가에 기인하는 것으로 사료되었다.

Background: Endotracheal intubation during anesthesia induction may increase airway resistance ($R_{aw}$) and decrease dynamic lung compliance ($C_{dyn}$). We hypothesized that prophylactic treatment with a transdermal ${\beta}2$-agonist tulobuterol patch (TP) would help to reduce the risk of bronchospasm after placement of the endotracheal tube. Methods: Eighty-two American Society of Anesthesiologists (ASA) category I or II adult patients showing obstructive patterns were divided randomly into a control and a TP group (n = 41 each). The night before surgery, a 2-mg TP was applied to patients in the TP group. Standard monitors were recorded, and target controlled infusion (TCI) with propofol and remifentanil was used for anesthesia induction and maintenance. Simultaneously, end-tidal carbon dioxide, $R_{aw}$, and $C_{dyn}$ were determined at 5, 10, and 15 min intervals after endotracheal intubation. Results: There was no significant difference in demographic data between the two groups. The TP group was associated with a lower $R_{aw}$ and a higher $C_{dyn}$, as compared to the control group. $R_{aw}$ was significantly lower at 10 min (P < 0.05) and 15 min (P < 0.01), and $C_{dyn}$ was significantly higher at 5 min (P < 0.05) and 15 min (P < 0.01) in the TP group. A trend towards a lower $R_{aw}$ was observed showing a statistically significant difference 5 min after endotracheal intubation (P < 0.01) in each group. Conclusions: Prophylactic treatment with TP showed a bronchodilatory effect through suppressing an increase in $R_{aw}$ and a decrease in $C_{dyn}$ after anesthesia induction without severe adverse effects.

This study was done to evaluate the effect reducing artificial dead space on intubated children. Data were collected from July 1st, 1998 to August 31st, 1999. The subjects were selected from a pediatric intensive care unit of 'S' hospital and intubated with 3.5 mm or 4.5 mm endotracheal tube after open heart surgery. They were composed of 34 patients : 17 patients were assigned to the experimental group and the rest of them were placed in the control group. The artificial airway volume was minimized in the experimental group, and the control group maintained the artificial airway volume. ETCO2, PaCO2, SPO2 were measured as indicators of pulmonary ventilation. The tools of this study were GEM-Premier and Space-Lab patient monitors. The data were analyzed using the SPSS/PC+ program. The $\chi$2 -test was used to find general characteristics. The t-test was used to test the homogenety of the pulmonary ventilation status and mechanical ventilation setting before intervention between the two groups. Also, the paired t-test was used to examine the hypothesis. The results can be summerized as : 1. CO2 can be expelled effectively from the body in case artificial dead space was decreased. 2. As the artificial dead space was reduced, the difference between ETCO2 and PaCO2 was decreased, in other words pulmonary ventilation was improved. 3. If the artificial dead space occupied above 15 percent of tidal volume, the effect of CO2 was retention revealed in the body. 4. If the artificial dead space occupied below effect. Based on the results, the following is suggested to be applied practically : 1. A kind of the ventilator circuit acting artificial dead space should be removed from the intubated children with mechanical ventilaion. 2. The endotracheal tube should not be cut because extra-body space of the endotracheal tube did not have an effect on the dead space of the intubated children. Since the researcher could not cover this aspect in the study, they recommend the following. 1. The study should be extended to the other pulmonary disease patients for the effect of improving pulmonary ventilation. 2. Also, further studying with a more narrow interval in the extra-body space of the artificial airway will be able to explain the point of artificial dead space with proper ventilation.

한 41세 남자 환자가 충수돌기염 절제술을 받기 위하여 전신마취를 받았다. 삽관을 위해 후두경으로 보자, 난해한 기도삽관이 예상되어 유도자를 사용하였다. 기도삽관 중 돌출된 유도자가 기도를 손상시켰으며, 이에 의해 목에서부터 상부종격동까지의 피하기종과 목의 염증성 종창이 생겼다. 환자는 호흡곤란과 관련된 증상을 보이지 않아 호흡기의 손상을 의심하기 어려웠고, 주 증상이었던 염증성 종창에 초점을 두게 되어 진단에 차질을 빚었으나, 환자는 대증치료로 회복하였다. 유도자를 사용하여 기관내 삽관을 하는 경우 유도자의 위치를 재점검하여 유도자에 의한 기도 손상을 유발하지 않도록 유념해야 할 것이다.

Untreated massive hemoptysis, especially in patients with tuberculous-destroyed lung, is a serious complication resulting in considerable morbidity and mortality. We report a case of a patient who had active tuberculosis and a destroyed left lung with massive bleeding. He was transferred to our clinic with intubation of a right-sided Robertshaw double lumen tube and right upper lobe collapse likely due to tube malposition that was presented on chest X-ray. Because hemoptysis had persisted after bronchial arterial embolizaton, we replaced the double lumen tube with a conventional endotracheal tube and inserted an endobronchial blocker into the left main bronchus through an endotracheal tube guided by bronchoscopy to prevent aspiration of blood into the right lung. Left pneumonectomy was performed and hemotpysis was ceased. We suggest that the use of an endobronchial blocker followed by surgery may be a safe and effective modality of treatment in patients with persistent bleeding after bronchial arterial embolization.
