The purpose of this study was to develop a suction care education program and to evaluate the effects on clinical performance, self-efficacy, and problem-solving process regarding suction practice. The participants were 96 in second-year nursing students at P university in Pusan, Korea. The data was collected from Oct. 6th toward Oct. 19th, 2011, and analyzed by ${\chi}^2$, t-test, ANCOVA test using SPSS 18.0. The scores of clinical performance were 23.72 in the experimental group who learned this program and 22.16 in the control group, and were statistically significant(p<.001). Self-efficacy were 7.58 in the experimental group and 7.08 in the control group, which was statistically significant(p=.03), and the pre-to-post difference of self-efficacy was statistically significant as well(p<.001). However, there were no significant differences in the problem-solving process(p=.06) and the pre-to-post difference related to this(p=.011). This study showed that clinical performance and self-efficacy were improved by suction care education program.

미숙아에 있어 주로 표면활성제의 부족으로 인한 호흡곤란증은 미숙아 사망의 주원인이 된다. 호흡곤란증의 치료목적은 적절한 환기를 통해 체내 산소화를 유지시키는 것이다. 인공호흡기 치료를 받는 미숙아에게 필수적인 간호중재인 기관지 흡인술은 그 효과를 극대화하기 위해 흉곽진동법과 같이 사용될 수도 있다. 그러나 미숙아를 대상으로 하는 흉곽진동법은 그 중재의 안전성이나 효과에 대한 과학적 검증 없이 시행되고 있는 실정이다. 이에 본 연구는 호흡곤란증 미숙아에 있어 기관지 흡인술 이전에 행하여지는 흉곽진동법이 산소화와 기관지 분비물에 미치는 영향을 연구하기 위해 실시되었다. 이를 위해 20명의 호흡곤란증 미숙아를 대상으로 대상자내 반복실험연구가 설계되었다. 독립변수는 기관지흡인술이전에 흉곽진동이고 종속 변수는 산소 포화도, 심박동수, 그리고 기관지 분비물의 양이었다. 각 대상자는 무작위 순서에 따라 한번은 흉곽진동없이 흡인을, 나머지 한번은 흉곽진동과 흡인의 두 가지 형태의 흡인을 경험 하였다. 연구 결과, 기관지 흡인술이전에 흉곽진동을 실시하든, 안하든 산소포화도와 심박동수의 변화양상에는 차이가 없었다. 그러나, 융곽진동법을 실시한 경우가 실시안한 경우에 비해 더 많은 양의 기관지 분비물을 흡인하였다. 이는 기관지 흡인술 이전에 실시하는 흉곽진동법이 미숙아의 체내에 부가적 산소소모를 초래하지 않는 반면, 기도로부터 더 많은 분비물을 흡인하는데 효과적임을 시사한다.

Purpose: This study was conducted to identify the effects of a suction care self video-based debriefing-assisted learning in the fundamentals of nursing practice for nursing students on clinical performance, self-efficacy and problem-solving process. Methods: A nonequivalent control group non-synchronized design study was used and included 97 junior nursing students at P University as participants, 48 of whom were assigned to the experimental group, and 49 of whom were assigned to the control group. The outcome measurements were clinical performance for suction care, self-efficacy, and the problem-solving process. Results: The scores of clinical performance were 23.75 in the experimental group who used the materials and 21.55 in the control group, and the difference was statistically significant (p<.000). Self-efficacy was 4.30 in the experimental group and 4.18 in the control group, which was a statistically significant difference (p=.000), and the pre-to-post differences of self-efficacy was statistically significant as well (p<.001). However, there were no significant differences in the pre-to-post differences of the problem-solving process (p<.802). Conclusions: Self video-based debriefing-assisted learning may be more effective in enhancing clinical performance and self-efficacy than that of conventional practice. Whether self-efficacy will contribute to enhanced learning motivation for nursing students needs further examination.

Purpose: The purpose of this study was to examine the effects of a closed endotracheal suction system(CES) on oxygen saturation, ventilator associated pneumonia(VAP), and nursing efficacy in mechanically ventilated patients. Method: This study was conducted in the intensive care unit of a University Hospital in Gwangju City. Data was collected from July to October, 2003. Seventy mechanically ventilated patients were randomly divided into two groups; 32 for CES and 38 for open endotracheal suction system(OES) protocol. Twenty one nurses were also involved to examine the nurses' attitude of usefulness about CES. Result: $SaO_2$ was significantly different between CES and OES. The incidence of VAP in CES was lower than that of OES. Nursing efficacy was related to time, cost, and usefulness of the suction system. Time of suctioning in CES was shorter than that of OES. CES also contributed significantly to lower the cost of treatment than OES. The usefulness score of CES increased after 6 months of use. Conclusion: CES prevented VAP, was cost effective, and a safe suctioning system. CES can be used with patients with sensitivity to hypoxygenation and with a high risk of VAP.

Purpose: The purpose of this study was to compare the difference of change in oxygen saturation, vital signs and suction time taken for the suctioning during endotracheal suctioning performed with closed suction system and with opened suction system. Methods: Data were collected from 31 adult patients with ventilator treatment who were admitted to a university hospital in Seoul and the collection period was from July 1 to November 15, 2005. Oxygen saturation, heart rate, respiration rate and mean arterial pressure were collected immediately prior to the suctioning intervention, during and 1 and 5 minutes after the suctioning from opened suction system and closed suction system. Results: 1) The difference in oxygen saturation was statistically significant in recovery time for oxygen saturation to return to baseline values after suctioning was significantly rapid on closed suction system (p<.05). 2) The difference in heart rate, respiration rate and mean arterial pressure was statistically insignificant 3) The suction time was shorter in closed suction system. Conclusion: Closed suction system is more efficient, as compared with the open suction system in the ventilator treatment.

Purpose: The purpose of this study was to check the degree of residual microbial contamination after disinfection of reusable suction containers, used in an intensive care unit (ICU) and present basic data for efficient use through cost analysis in comparison to disposable suction containers. Methods: This study was conducted on 32 reusable suction containers used in an ICU on a selected specific day. After disinfection and washing, specimens were collected from the used containers and cultured to check for microbial contamination. Additionally, a comparative narrative study analyzes the cost of using reusable suction containers and disposable suction containers. Data were analyzed with the SPSS WIN 20.0 program using real numbers and percentage ${\chi}^2$-test. Results: As a result of the study, microorganisms were found in all samples where in 30 were gram-positive (62.5%) while 13 were gram-negative (27.1%). Based on level of contamination, microorganisms were less than 10CFU/ml in 18 samples (56.3%); 11-99CFU/ml in six samples (18.8%); and more than 100CFU/ml in eight samples (25%). Cost per day for a reusable suction container was $10,655+{\alpha}$ while cost per day for a disposable suction container was 10,666 won. Conclusion: This study found that reusable suction containers, even after disinfection, accounted for factors of potential infection as well as microbial contamination. So, disposable suction containers are superior in cost-effectiveness and highly efficient for use with infected patients.

Purpose: This study was conducted to develop standards to ensure nursing process-based care of oxygen therapy and airway suctioning and to develop a performance measurement tool to evaluate the care applied according to the standards, and finally to determine validity of the standards and the tool. Methods: The standards and the tool were reviewed by a panel of experts and refined based on the panel's suggestions. Validity of the standards and the tool were examined through surveying a total of 366 hospital nurses. Results: The mean validity scores of the performance measurement standards and the tool were 3.58 and 3.55, respectively, out of 4.00. So the performance measurement standards and the tool in this study were found to be acceptable in evaluating quality of nursing care provided at patient admission and discharge. Conclusion: This result indicates that the performance measurement standards and the tool developed in this study are valid instruments to monitor and improve quality of nursing care for oxygen therapy and airway suctioning.

Purpose: This study was conducted to investigate the effects of the suction-induced hypoxemia interventions. Method: 30 suction-induced hypoxemia interventions were reviewed for the purpose of meta-analysis. Result: The study showed that both preoxygenation and insufflation were the most frequently examined oxygenation time periods, and hyperoxygenation combined with hyperinflation was the most commonly applied oxygenation method in order to prevent suction-induced hypoxemia. The greatest effect was obtained by providing oxygenation before and after suctioning, whereas negative effect(the contrary results from the study hypotheses) was frequently obtained by applying insufflation only. Applying hyperoxygenation combined with hyperinflation had the greatest effect over that of applying hyperoxygenation only, even though the difference between effect sizes of both methods were statistically significant. Conclusion: The results of meta-analysis showed that the occurrence rate of hypoxemia after suctioning was significantly reduced with the overall interventions for hypoxemia (decreasing 40% of occurrence rate), independent with time periods or methods for providing oxygenation.

Purpose: This study aimed to evaluate the adherence to the clinical guideline for endotracheal suction in nurses working at intensive care units (ICU) and to identify the characteristics of nurses with good adherence. Methods: This study was a descriptive study to evaluate the pattern of adherence and its related factors to endotracheal suction. One hundred fifty five nurses working at ICU participated in this study. We used a questionnaire developed based on American Association for Respiratory Care (AARC) guidelines and other associated factors from previous studies. Results: Around half of the participants reported that their adherence to the clinical guideline was poor. Items deviated from the recommended guideline were reasons for initiating a suctioning, applied suction pressure ranged from 20 to 200mmHg, and applied catheter size from 6 to 17 french. Other factors deviated were the depth of inserted catheter, and inappropriate use of normal saline instillation. The most significant factor was related to hospital; the misused or misled clinical protocol. Conclusions: The adherence to the clinical guidelines of the endotracheal suction in ICU nurses was not appropriate, which might contribute to the patient health outcomes. More enhanced continuing education as well as hospital regulation is warranted.

Purpose: This study aimed to survey caregivers of patients with Neuromuscular Rare and Incurable Disease (NRID) using invasive home mechanical ventilator (HMV), in order to compare the incident rate of pneumonia by tracheal suction procedures used. Method: Participants were 99 family caregivers of NRID patients using HMV. Participants were given a questionnaire consisting of 12 demographic items, 10 items about disease and HMV related characteristics, 11 items about tracheal suction procedures, and 2 items about the incidence of pneumonia. Data were analyzed using chi-square tests and t-tests. Results: The items that predicted the incidence of pneumonia were "change of irrigation saline every suction" (p=.047), "use of aseptic catheter every suction" (p=.004), and "instillation of normal saline before suction" (p=.027). In addition, these items were 47.4%, 51.4%, and 38.8% respectively. Conclusion: Family members caring for NRID patients with invasive HMV should be educated about tracheal suction, especially the necessity of changing irrigation saline after every suction, using the aseptic catheter for every suction, and instillation of normal saline before suction. Medical personnel such as home care nurses should periodically check tracheal suction procedures, and re-educate family caregivers when necessary.
