Background: The image and status of anesthesiology as a medical specialty in the eyes of the general public has been a problem. This study assessed the patients` thoughts on anesthesiologists and their preoperative concerns and examined the influence of any previous anesthetic experience on their apprehension. Methods: One hundred thirty-nine patients undergoing elective surgical procedures were surveyed with a questionnaire regarding their thoughts on anesthesiologists and their preoperative concerns at preoperative visits. The results were analyzed in terms of a previous experience with anesthesia. Results: Sixty-five patients had previous experience with anesthesia (Group 1), and 74 patients had none (Group 2). Seventy-one percent of patients in Group 1 and 80% in Group 2 reported that a physician-anesthesiologist was in charge of their anesthesia. Regarding the responsibility for the patients` safety during the surgical procedures, 83% of patients in Group 1 and 82% in Group 2 reported that the anesthesiologists were responsible for the patients` well-being. Fifty-seven percent of patients in Group 1 and 58% in Group 2 reported that the anesthesiologists were responsible for their safe recovery from the anesthesia. The most frequent preoperative apprehensions were postoperative pain (57% in Group 1 and 62% in Group 2) and the risk of not waking up from the anesthesia (60% in Group 1 and 57% in Group 2). There were no significant differences between the two groups. Conclusions: Passive learning from previous anesthetic experience does not affect the patients` thoughts on the anesthesiologists and their preoperative concerns.

Background: Patient-controlled sedation (PCS) with propofol is a safe and effective method of attenuating discomfort during fiberoptic bronchoscopy. The purpose was to evaluate the usefulness of midazolam in addition to PCS for fiberoptic bronchoscopy. Methods: We randomly assigned 155 patients undergoing diagnostic bronchoscopy to two groups. Group M (n=79) received 0.03 mg/kg of midazolam for premedication while group P (n=76) received a loading dose (0.05 ml/kg) of PCS solution composed of 200 mg (20 ml) of propofol and 1 mg (2 ml) of alfentanil. Both groups received the PCS solution 0.2 ml/kg/hr with a bolus of 1 ml and a lockout time of 1 min. Vital signs, pulmonologist satisfaction, patient satisfaction and amnesia were evaluated. Results: After the insertion of the bronchoscope, there was a slight decrease of SpO2 and an increase of blood pressure and heart rate in both groups with no significant differences between the two groups. The group P required more bolus injections (1.6±1.7 in the group M vs 2.5±2.2 in group P; P<0.05). There was no difference in the satisfaction of pulmonologists, but the satisfaction of patients was higher in the group M (P<0.05). More patients in the group P (93%) remembered the procedure than in the group M (70%) (P<0.05). Conclusions: PCS is an effective method for sedating patients undergoing fiberoptic bronchoscopy and midazolam provides more patient satisfaction and amnesia. (Korean J Anesthesiol 2009;56:1~5)

본 연구는 어린이집에서의 놀 권리 존중에 대한 교사와 유아의 경험과 의미에 대해 살펴보았다. 집중 참여관찰과 면담을 통해 자료를 수집하였으며, 수집된 자료를 반복해서 읽으면서 공통적으로 드러나는 주요 사례를 추출하여 의미를 해석하였다. 어린이집에서 놀 권리 존중에 따른 교사의 경험과 의미는 첫째, 막연한 두려움과 혼란 속에서 자신을 내려놓고 또 내려놓기를 반복하며 가까스로 힘겨운 첫발을 내딛고 있었다. 둘째, 연구에 참여한 교사들은 점점 아이들에게 귀를 기울이며 좋은 청취자가 되어 놀 권리란 유아들에게 주는 것이 아니라 돌려주는 것임을 깨닫고 유아들에게 함께 발맞추는 교사로 나아갔다. 유아의 경험은 첫째, 보이지 않는 벽을 허물고 나와 저마다의 공간과 시간을 향유하며 놀이의 경계를 넘나들고 있었다. 둘째, 유아들의 놀이는 서로 만나고 소통하고 교류하며 놀이에 놀이를 더해가고 있었다. 본 연구는 유아들의 놀 권리 존중을 위한 교사들의 노력을 통해 비로소 유아들의 시선에 발맞추는 교사로 나아가게 되었으며, 놀 권리를 존중받은 유아들은 놀이의 경계를 넘어 진정한 놀이의 주체로서 놀이를 향유 할 수 있었음에 의의가 있다. The purpose of this study is to examine the experiences of teachers and young children with "right to play" and its meaning in a preschool educational institution. Data were gathered by intensive participant observations and interviews and the collected data were repeatedly read to extract major cases to interpret their meanings. The findings of the study on the experiences of the teachers with "right to play" in the preschool educational institution and its meaning were as following: First, the teachers kept emptying their minds in fear and confusion barely managing to take the first step. Second, the teachers gradually grew to listen to young children carefully, becoming good listeners, and they realized that "right to play" was not what was given to children, but what was returned to them, and they became teachers who kept pace with the children. The findings of the study on the experiences of the young children were as below: First, the children crossed the border of play as they broke down the hidden wall among themselves and enjoyed their individual spaces and time. Second, the children enriched their play by encountering, communicating and interacting with one another. This study is significant in that the teachers improved themselves to look at things from young children"s perspective and that the young children whose "right to play" was respected, were able to enjoy playing as the main agents, crossing the border of play.

워드클라우드 방법을 통해서 본 놀이에 대한 유아교사의 인식

권은정(Kwon, Eun-Jeong),손원경(Son, Won-Kyoung) 한국열린유아교육학회 2022 열린유아교육연구 Vol.27 No.3

본 연구는 놀이에 대한 유아교사의 인식을 살펴보고자 현재 유아교육기관에 근무하고 있는 유아교사 330명을 대상으로 개방형 설문조사를 실시하고 워드클라우드 방법으로 분석하였다. 연구결과 놀이에 대한 유아교사의 인식유형을 놀이본질, 놀이가치, 놀이환경, 교사역할로 나눌 수 있었다. 첫째, ‘놀이본질’은 놀이에만 내재하는 고유한 존재를 구성하는 것으로 즐거움, 자유, 몰입 등과 같은 놀이의 속성과 놀이틀과 같은 놀이구조의 내용을 포함하고 있었다. 둘째, ‘놀이가치’는 놀이로 인한 현상, 행위 등이 유아에게 의미있고 바람직한 것임을 나타내는 유아의 성장과 발달, 놀이의 역할과 기능을 포함하고 있었다. 셋째, ‘놀이환경’은 놀이에 직간접적으로 영향을 미치는 자연적, 사회적인 조건이나 상황으로 물리적 환경인 자연, 안전, 공간 등에 대한 인식이 포함되었다. 넷째, ‘교사역할’은 놀이를 마주하고 있는 교사의 입장과 생각에 대해 교사의 개입과 지원, 놀이확장, 교사교육의 내용을 포함하고 있었다. 따라서 본 연구는 놀이에 대한 유아교사의 인식을 살펴봄으로써 유아놀이에 대한 효과적인 현장지원의 기초자료를 제시할 수 있을 것이다. The purpose of this study was to examine the perceptions of early childhood teachers about play. Thus, the open-ended questionnaire survey was conducted targeting 330 early childhood teachers who are now working at early childhood education institutions. As a result of the research, the types of early childhood teachers’ recognition of play could be divided into the play essence, the play value, the play environment, and the teacher role. First, as the ‘play essence’ is what establishes play and constructs a unique existence inherent in play, it was including the attributes of play such as enjoyment, freedom, immersion, etc. and the contents of the play structure such as a play frame. Second, the ‘play value’ was covering the growth and development in childhood and the role and function in play of showing that the phenomena and actions caused by play are meaningful and desirable for toddlers. Third, as the ‘play environment’ is natural and social condition or situation that directly or indirectly affects play, it was involved the perceptions of nature, safety, space, and teaching aids, which correspond to the physical environment. Fourth, the ‘teacher role’ was including the teacher intervention and support, the expansion of play, and the contents of the teacher education with regard to the position and thoughts of teachers facing play. This study figured out how the early childhood teachers’ recognition of play changes and proceeds with being formed by harmonizing with the field experience. Therefore, this study will be able to present basic data on effective field support for infant teachers’ perceptions of play.

The determination of arterial pressure wave-derived cardiac output (APCO) and central venous O2 saturation (ScvO2) has been introduced as a less invasive procedure for monitoring cardiac function and oxygen delivery. We have used an APCO sensor (FloTrac(TM)) and a monitor for ScvO2 (Vigileo(TM)) in two cases of cardiac valve surgery, where placement of pulmonary artery catheter (PAC) was not applicable due to unfavorable cardiac structure (case 1) and was contraindicated due to an unstable cardiac conduction disorder and arrhythmia (case 2). In case 1, monitoring of APCO was started from the beginning of anesthesia induction and a ScvO2 monitoring central venous catheter was inserted just after anesthesia induction. APCO, ScvO2 and other hemodyanamic information such as arterial BP, CVP, and data obtained from transesophageal echocardiography (TEE) during the pre-cardiopulmonary bypass (CPB) period were measured. APCO and ScvO2 during the post-CPB period showed a reliable correspondence with continuous cardiac output (CCO) and mixed venous O2 saturation (SvO2) as measured by PAC at the end of CPB. In case 2, APCO and ScvO2 were monitored instead of CCO and SvO2. The values of APCO showed a good correlation to intraoperative COs indirectly calculated by the velocity-time integral of the aortic outflow determined in the TEE examination. We experienced that monitoring APCO and ScvO2 is useful for anesthesia management in cardiac valve surgery and can be an alternative to CCO and SvO2 if the placement of PAC and the thermodilution method are not applicable.

The purpose of this study was to investigate the current status of the need of telephone call and to identify the status of nursing intervention through telephone. Head nurses of the pediatric nursing unit and a nurse of pediatric outpatient clinic wrote down the telephone record of calls by parents of children discharged from hospital from 7 am to 3 pm during the period of March to June, 1995. Content of 120 telephone calls but for 26 calls with incomplete record among 146 calls were analyzed into frequency of general characteristics, needs and nursing intervention. The needs of telephone call were identified and classified into 11 areas and analyzed into frequency of detailed content by 11 areas. Nursing intervention was identified and classified into 10 categories, and analyzed into frequency of detailed content by 10 categories. The findings of this study were as follows ; The need of telephone call was identified with nutritional state, medication, vital signs, language retardation, personal hygiene, vaccination, administration procedure, physical symptoms, follow up care management and others. The most frequent needs were physical symptoms and vaccination. A kind of food among nutrition dose of drugs among medication, fever among vital signs, cough among physical symptoms, and content of vaccination among vaccination was the most frequent needs. Nursing intervention through telephone was identified with instruction, knowledge offer, information offer, judgement, solicitation, referral and instruction, referral, connection, reassurance, reservation, and regulation. Instruction, knowledge offer and information offer was the most frequent nursing intervention by telephone call. Instruction was about a visit to hospital, a visit to nearby clinic, instruction about symptoms,, instruction about nursing care procedure, retelephoning and vaccination. Knowledge offer was about vaccination, knowledge related to medication, and dental care. Information offer and judgement was about vaccination and medication. Referral and instruction delivery was about instruction delivery following consultation to doctor, visit to emergency room and a visit to hospital following consultation to doctor. These results suggest that telephone call intervention program should be established as a field of extended pediatric nursing role in health care delivery system for the children.

Background: Risk for injuries resulting from overinflated or underinflated endotracheal tube cuff warrants adequate cuff inflation technique. Thus, this study was designed to measure the actual intracuff pressures obtained by new estimation techniques. Methods: 95 adult surgical patients requiring tracheal intubation were randomized to two groups with respect to the endotracheal tube model: Portex(R) (n=55) and Euromedical(R) (n=40). After induction of anesthesia, the cuff was inflated using new estimation techniques with two different syringes: PR10 or PR20 (passive release technique using a 10-ml or 20-ml syringe, respectively). Subsequently, an aneroid manometer was used to measure the actual intracuff pressures. These inflation techniques were repeated two times. A direct cuff measurement range of 25 to 40 cmH2O was used as a reference for optimal intracuff pressure. Size 7.0 mm internal diameter (ID) tubes were used for women and size 7.5 mm ID for men. Results: 88 eligible patients were studied: Portex group (n=50) and Euromedical group (n=38). With respect to the rate of optimal cuff inflation, PR10 was significantly higher than PR20 in both groups (56% vs. 10% in Portex group; 63.2% vs. 0% in Euromedical group, respectively) (P<0.05). Conclusions: When direct intracuff measurement is not available, a new method, named "passive release technique" using a 10-ml syringe, is a useful alternative cuff inflation method.
