An Innovative Technique for Fluid Infiltration Using Double-Bent Needle.

Local infiltration of tumescent fluid and saline is required in various surgical procedures such as liposuction and hair transplant surgery. The use of small-caliber needles requires more time and power for injection, especially in the superficial planes of the skin.1 The use of large-caliber needles has a few drawbacks. These include painful infiltration and lack of control of the volume injected. Moreover, there are high chances of needle injections into the vessels, and intravascular injections may occasionally result. Various techniques have been developed to avoid the complication. One technique is to use blunt needles or cannulas or short needles. Another is to bend the needle and keep the full length of the needle parallel to the skin to avoid injuring deeper structures (Fig. 1).Fig. 1.: Single-bent (above) and double-bent (below) needles.We have developed a new technique in which large-caliber needles can be used to inject larger volumes without any fear of injuring deeper structures or risking intravascular injections, as described below. [See Video 1 (online), which demonstrates how to make a double-bent needle.] {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 1.","caption":"Method for making a double-bent needle.","object-id":[{"pub-id-type":"doi","id":""},{"pub-id-type":"other","content-type":"media-stream-id","id":"1_elkyvaex"},{"pub-id-type":"other","content-type":"media-source","id":"Kaltura"}]} Hold the needle in the needle holder at about 3 to 4 mm from the tip, with the eye of needle facing up. Bend the needle at a right angle in a counterclockwise direction to create the first bend (point A) (Fig. 1, above). Hold the needle at about 2 to 3 mm proximal to point A and bend in a clockwise position at a right angle to create the second bend (point B) (Fig. 1, below). The direction of the distal part can be adjusted as well (Fig. 1, below). The use of a bent needle is not new in the medical literature. The bent needle is used in dentistry for intraoral nerve blocks and for supraclavicular regional blocks.2,3 The bent needle with broken tip is also used in plastic surgical procedures for irrigation. Similarly, the double-bent needle has been used in intraocular injections as well.4 We have developed this new technique to inject large amounts of fluid without any fear of intravascular injection, especially in the subcutaneous plane. In order to maximize safety, the eye at the bevel is faced upward. [See Video 2 (online), which shows application of the double-bent needle.] The bending of the needle at two points also decreases the lumen of the needle, which decreases the flow rate as well. The part between the two bend serves as depth control. {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 2.","caption":"Clinical application of double-bent needle.","object-id":[{"pub-id-type":"doi","id":""},{"pub-id-type":"other","content-type":"media-stream-id","id":"1_8mnc7h8g"},{"pub-id-type":"other","content-type":"media-source","id":"Kaltura"}]} Avoid a second attempt to bend or twist the needle, as that may weaken the needle and it may break and can cause needle tip impaction.

The perspectives of health care professionals on self-administration of medication - a field study in a general surgical ward

Aim : To investigate the perspectives of healthcare professionals on self-administration of medication for patients admitted to a general surgical ward. Background: Self-administration of medication focuses on patient involvement in care and increases patients’ insight into prescribed medication. However, concerns and resistance from health professionals regarding self-administration may be an obstacle. Methods: A field study with participant observation and qualitative interviews included 7 healthcare professionals: 3 pharmaconomists and 4 nurses. Data analysis took a phenomenological-hermeneutic approach. Results: The study revealed 3 themes: firstly, “getting through the eye of the needle” was about the processes by which patients were evaluated as being suitable for self-administration; secondly, “being in control and losing control” reflected the importance of having control over medication processes and the fear that relinquishing control would result in medical errors; thirdly, “insight and independence” reflected health professionals’ recognition that patients performing self-administration gained greater insight into their medication and a greater sense of independence. Conclusion: Implementation of self-administration of medication illustrated the dilemma health professionals are facing with a healthcare system changing from a paternalistic ideology, where nurses are expected to be in control of the medication, to a patient empowerment participation ideology where the professionals have to relinquish control of the administration of medication and support patient autonomy and this was difficult for the nurses. Lack of knowledge about how to provide care in an empowerment participation ideology resulted in insufficient communication with patients about administration of medication and could result in medication errors.

Mechanical behavior investigation of press-fit connector based on finite element simulation and its reliability evaluation

As the successor of soldering, the press-fit electrical connection is more and more widely used on account of a number of advantages, such as fast assembly. However, in practice, some contact failures were found. Most of the failures are related to the force which the structure bears. Because of complex elastic-plastic deformation characteristic, analyzing the mechanical behavior of the press-fit is challenging. Some studies have been done on the assembly force behavior of the press-fit such as press in force. However, the stress behavior on the assembly is not clearly studied. In this paper, the mechanical behavior of a typical press-fit connector named as eye of needle (EON) was investigated based on finite element (FE) simulation. Firstly, FE models were established and verified. Then, basing on model analysis, the mechanical behaviors (mechanical stress, thermal stress, and contact force) of the EON were obtained, which makes it clear that the relationships between the EON's structural parameters and its work conditions. Finally, the long-term reliability of the EON connector under the stress relaxation and the thermal fatigue was evaluated, respectively. The FE models here are effective on analyzing the press-fit mechanical behavior, which can be adopted to help design and manufacture.

Study on the Contact Performance of Electronic EON Connectors Under Axial Vibration

One of the main failure mechanisms of electronic connectors is fretting wear induced by vibration. In this paper, three connectors having different eye-of-needle (EON) pins were investigated for their mating and vibration performances with assembling of different sized and surface-treated printed circuit boards (PCB). In addition to experimental measurement, quasi-static finite-element analysis was also employed in the study of the mating between the EON pin and PCB hole. The results indicated that the retention force was higher when the EON pin was assembled with larger sized hole under lower bound specification. Therefore, higher retention force can be maintained by using appropriate-sized hole or interference. Moreover, according to analysis of variance based on the performance characteristics of retention force and electrical contact resistance, the significance of design factors, i.e., PCB hole size and surface treatment, could be evaluated. Finally, in the vibration test, the sinusoidal excitation level was normalized in accordance with the above experimental results in the retention force of each connector. It was found that under the constant EON size, hole size was the significant control factor in the retention force of mating pair. On the other hand, surface treatment was the significant control factor in the electrical contact resistance. Under vibration test, the control factor of surface treatment on the PCB panel was more significant in determining the electrical contact resistance of the connector than the interference factor.

In Search of the Divide Between the Local and the Global

Conventionally, and global are understood to be distinct cultural spaces. While is considered as a unitary site, and thus location of home, global is regarded as other. However, in this era of globalization, has become very difficult to maintain this distinction. There is a sense of global in local, and vice versa. Moreover, contrary to conventional assumptions, both and global are actively transforming and being transformed by each other. It is therefore inaccurate to view as a passive player, either removed from global influence or waiting to be influenced by global. Stuart Hall, in and Global: Globalization and Ethnicity (1997), demonstrates danger of viewing identities and places as stable points of reference that were like that in past, are now and ever shall be, still points in a turning world (175). In his view, locality turns with rest of world, and through eye of needle of other before can construct itself (174). In other words, every place is connected to another place. Hall has also noted globalization's role in the erosion of nation-state and national identities that are associated with it (177). Indeed, according to him, different subject-positions are being transformed or produced in course of unfolding of new dialectics of global (173). It is not only Hall who sees a link between and global.Bill Ashcroft, author of Post-Colonial Transformation (2001), has made a similar observation: diffusion of global influence makes relationship between and global all more complex, because when we examine cultures we find presence of global within to extent that compels us to be very clear about our concept of local (215). Ashcroft's view that we can no longer look at in isolation from global is persuasive; however, is arguably compromised by its top down approach. That is, wrongly suggests that contest between global and is one-way, and that is only on receiving end. In any case, presence of global in has implications for our perception of home, one of which is difficulty of separating home from world. There is a need to configure a global sense of home, so as to account for threads of global culture and relations that interweave fabric that we call home.In their introduction to Globalization and Identity: Dialectics of Flow and Closure (1999), Birgit Meyer and Peter Geschiere call for an understanding of globalization that not only takes into account rapid increase in mobility of people, goods, and images, but also fact that, in many places, flow goes hand in hand with a closure of identities which often used to be much more fuzzy and permeable (2). In other words, while some people seem open to globalization, others resist by affirming what they consider as their endangered identities. This resistance is based on fear that globalization is cultural imperialism by any other name, and that in time would consume cultures. While this fear is in some ways justified, does not change fact that there are no absolute boundaries unaffected by global flows (Meyer and Geschiere 5). Nevertheless, space is too complex and active to be erased by global flows. As Henry Lefebvre, in The Production of Space (1991), puts it, We are confronted not by one social space but by many - indeed, by unlimited multiplicity or uncountable set of social spaces which we refer to generically as 'social space'. No space disappears in course of growth and development: worldwide does not abolish local (86). Nevertheless, globalization has impact on local, impact that affects our understanding of home.In a similar vein, Arif Dirlik, in Global in Local (1996), shows relationship between and global by arguing that boundaries of are open. …

I Am the Eye of the Needle and Everything Passes through Me: primary headteachers explain their retirement

ABSTRACT Fourteen early retiring primary headteachers in individual and group interviews discussed their decision to apply for early retirement. Retirement decisions were affected by ‘pushes’ from the system and ‘pulls’ towards retirement. Perceived pushes were external pressures, job expansion/overload, bureaucracy, local authority support, loss of job satisfaction and school relationships. Pulls comprised ‘facilitators’ (personal and financial) and ‘gains’ (control, opportunities, health and family). Pushes against retirement comprised losses of positive school relationships, role and status, job challenge and time structure. Early retirement amongst these headteachers appeared to derive from current retirement trends, job stress and lack of management support.
