Phenomenology as research method or substantive metaphysics? An overview of phenomenology's uses in nursing

In exploring phenomenological literature, it is evident that the term ‘phenomenology’ holds rather different meanings depending upon the context. Phenomenology has been described as both a philosophical movement and an approach to human science research. The phenomenology of Husserl, Heidegger, Gadamer, and Merleau‐Ponty was philosophical in nature and not intended to provide rules or procedures for conducting research. The Canadian social scientist, van Manen, however, introduced specific guidelines for conducting human science research, which is rooted in hermeneutic phenomenology and this particular method has been employed in professional disciplines such as education, nursing, clinical psychology, and law. The purpose of this paper is to explore the difference between the phenomenological method as described by van Manen and that of other philosophers such as Husserl, Heidegger, Gadamer, and Merleau‐Ponty. In so doing, the author aims to address the blurred boundaries of phenomenology as a research method and as a philosophical movement and highlight the influence of these blurred boundaries on nursing knowledge development.     

Experience of intravenous sedation for pediatric gastrointestinal endoscopy in a large tertiary referral center in a developing country

Background: The aim of this study was to evaluate the clinical efficacy of intravenous sedation for pediatric gastrointestinal endoscopy (GIE) at a tertiary care teaching hospital in a developing country. Methods: We undertook a retrospective review of the sedation service records of pediatric patients who underwent GIE. All endoscopies were performed by a pediatric gastroenterologist. All of the sedation was administered by staff anesthesiologist or anesthetic personnel in the gastroenterology procedure room. Results: Sedation was provided for 222 procedures in 214 patients ranged in age from younger than 1 to 17 years and in weight from 2.7 to 80.0 kg. Intravenous sedation was provided in 176 patients (82.2%). Of these patients, 185 procedures were performed and reviewed, with 152 (82.2%) procedures were esophagogastroduodenoscopy (EGD) alone, 14 (7.6%) procedures were colonoscopy alone, 18 (9.7%) procedures were EGD and colonoscopy, and one procedure was endoscopic ultrasonography (EUS). Most common indications of the procedure were screening for esophageal varices (25.2%), abdominal pain (15.9%), history of upper gastrointestinal hemorrhage (13.6%), and unexplained anemia (10.3%). The majority of preanesthetic problems were hematologic disease, anemia (38.2%); liver disease, cirrhosis (13.5%); and electrolyte imbalance (13.5%). Propofol (94.0%), fentanyl (87.0%), and midazolam (67.8%) were frequently used. The mean dose of propofol was 7.8 ± 4.1 mg·kg^?1·h^?1, fentanyl 2.3 ± 1.1 mcg·kg^?1·h^?1, and midazolam 0.1 ± 0.1 mg·kg^?1·h^?1. Most of them were used in combination. The combination of propofol, fentanyl, and midazolam was commonly employed (46.4%). The mean sedation time of all procedures was 28.2 min and was different according to procedure type. Complications occurred infrequently (13.5%) and were medication or airway related. All complications were easily treated, with no adverse sequelae. Intravenous sedation was successful except for one patient who required general anesthesia. However, all procedures were completed successfully. Conclusions: In the setting of the developing country, intravenous sedation for pediatric GIE by trained anesthetic personnel with appropriate monitoring was safe and effective. Serious adverse events were rare in our population.     

Is coronary artery bypass grafting without cardiopulmonary bypass safe?

Lipohemarthrosis of the knee: a review of recent experiences

The radiographs of 268 patients with knee trauma were retrospectively reviewed. In 15 patients with intraarticular fracture, the images demonstrated fat-fluid levels. In 28 other patients with intraarticular fracture, only joint effusion without a fat-fluid level was depicted. The presence of a fat-fluid level in the knee indicated fracture in all patients in whom it was seen. The absence of such a level, however, did not exclude intraarticular fracture.     

The systems approach to error reduction: factors influencing inoculation injury reporting in the operating theatre

cutter j. & jordan s. (2012) Journal of Nursing Management
The systems approach to error reduction: factors influencing inoculation injury reporting in the operating theatre Aim To examine the frequency of, and factors influencing, reporting of mucocutaneous and percutaneous injuries in operating theatres. Background Surgeons and peri-operative nurses risk acquiring blood-borne viral infections during surgical procedures. Appropriate first-aid and prophylactic treatment after an injury can significantly reduce the risk of infection. However, studies indicate that injuries often go unreported. The ‘systems approach’ to error reduction relies on reporting incidents and near misses. Failure to report will compromise safety. Methods A postal survey of all surgeons and peri-operative nurses engaged in exposure prone procedures in nine Welsh hospitals, face-to-face interviews with selected participants and telephone interviews with Infection Control Nurses. Results The response rate was 51.47% (315/612). Most respondents reported one or more percutaneous (183/315, 58.1%) and/or mucocutaneous injuries (68/315, 21.6%) in the 5 years preceding the study. Only 54.9% (112/204) reported every injury. Surgeons were poorer at reporting: 70/133 (52.6%) reported all or >50% of their injuries compared with 65/71 nurses (91.5%). Conclusions Injuries are frequently under-reported, possibly compromising safety in operating theatres. Implications for nursing management A significant number of inoculation injuries are not reported. Factors influencing under-reporting were identified. This knowledge can assist managers in improving reporting and encouraging a robust safety culture within operating departments.     

夜班护士麻痹症状群:临床心理学的一种新现象?

夜间工作被认为可破坏生理节奏[1] ,而另一些卫生学专家认为夜间工作能引起抑郁症状反应[2 ] 。夜班护理工作确实可能成为一种特别的应激[3 ] ;因此实习护士常常需要心理支持 ,以帮助他们作好应对和适应的准备[4] 。对“夜班护士麻痹症状群”(ｎｉｇｈｔｎｕｒｓｅｓ’ｐａｒａｌｙｓ ｉｓ)这一现象曾有过报导[5] ,但尚没有科学研究来证明这种现象的存在。这种现象被描述为往往当护士在寂静不动时 ,有一种无力的感觉。例如护士在夜间坐病室观祭台执行观察任务时 ,神志清醒 ,但在短时间内不能按要求移动肢体。在这种情况下 ,他人的触动或低声…     

Needs and anxiety levels in relatives of intensive care unit patients

The purpose of this study was to explore the perceived needs and anxiety levels of adult family members of intensive care unit (ICU) patients. The study was conducted over a 3-month period, on a convenience sample of 166 subjects selected from the total adult population of family members visiting an ICU patient in three Sudbury hospitals. Data were gathered using a self-report questionnaire, the Critical Care Family Needs Inventory (CCFNI) and Spielberger's State Trait Anxiety Inventory (STAI). Interviews were conducted in French or English according to the subject's preference. The major variables examined were: family needs; state and trait anxiety; on-site sources of worry; spiritual needs; level of knowledge of ICU from past experience or pre-surgery education; sociodemographic data. The Situational Anxiety Scale yielded a mean score of 45.24 and the Trait Anxiety Scale a mean score of 37.3. Inferential statistics demonstrated that family needs and situational anxiety were significantly related (P less than 0.0002). Furthermore, worries, trait anxiety, age and family needs explained 38% of the variation of situational anxiety. As well, spiritual needs and situational anxiety explained 33% of the variation of family needs.     

A Comparative Study of the Experiences of a Group of Hong Kong Chinese and Australian Women Diagnosed With Postnatal Depression

PURPOSE.  This study examined the experiences of postnatal depression between a group of Chinese and Caucasian women.
DESIGN AND METHODS.  This was a secondary analysis of two phenomenological studies. Thirty-five Chinese women and 12 Australian women were interviewed.
FINDINGS.  Women felt being trapped in the depression. The Hong Kong women attributed their depression to their mothers-in-law and husbands, and expressed much anger. The Australian women attributed their depression to not being able to live up to the ideal mother image, and felt guilty.
PRACTICE IMPLICATIONS.  Interventions were recommended with consideration for the cultural values that influenced women's experiences of postnatal depression.     

马来酰亚胺苯甲氨酯聚乙二醇修饰膜蛋白掩盖AB和RhD抗原制备通用血型红细胞

聚乙二醇(PEG)上的活性基团结合在红细胞表面掩盖血型抗原是制备通用血型红细胞的途径之一,这些PEG链有很强的水合作用,能覆盖红细胞表面的大片区域,阻断血型抗原与抗体结合。甲基氧PEG-5000(mPEG-5000)是常用的红细胞修饰剂,主要修饰蛋白上的氨基基团。在氯化氰脲酸(CnCl)催化下,mPEG-5000与红细胞膜上氨基形成共价键连接,掩盖Rh抗原和A或B抗原。CnCl-PEG-5000浓度越高,血型抗原的覆盖效果越好。由于微环境下A和B血型抗原处无氨基基团或者氨基基团不能被CnCl-PEG-5000修饰,不能完全阻断抗-A、B与A和B血型抗原结合。本文报道…     

An evaluation of a strategy to improve the support of orthopaedic nurses through a team preceptorship programme

Transition to a new work area is often stressful for both experienced and new graduate nurses. It is essential that the new graduate be supported through this transition period to enable them to adjust to the environment itself, refine knowledge, and develop skills specific to their chosen clinical stream. In past years, several strategies have been designed with varying levels of success.This study evaluates an Australian transition support model, where the fundamental difference is that the management of the program is facilitated by a nurse possessing refined leadership, communication, clinical and organisational skills.The model has been evaluated on its effectiveness in meeting specific outcomes. The findings revealed that this coordinated team approach provided increased support for the new graduate, reduced the stress and workloads on the preceptors, whilst promoting confidence in the new starters and preventing conflict between preceptors and preceptees. The Coordinator’s role was shown to be an effective and crucial component in the Coordinated Team Preceptorship Model (CTPM) and findings illustrated that a team preceptorship model is not sustainable without a Coordinator.
