Grounded theory methodology has guided the grounded theory methods used to explore the acute care paediatric nurses' perspective of what they do when a child has had a severe accident.

Therefore this research has the potential of informing the speciality practice of acute care pediatric nursing.Nursing children in the acute care ward after a severe accident is complex. It encompasses nursing the family when they are experiencing a crisis. It is critical that the acute care nurse monitors and ensures the child's physiological needs are met, and the nurse "works with" the child to maintain and advance medical stability. Nursing interactions are an important part of "working with", communication is the essence of nursing. This research has focussed on the nurses' social processes whilst caring for the physical needs of the child and interacting with the family and multidisciplinary team when appropriate.An effective working-relationship with a nurse and family is founded on trust. Trust is an accepted part of our day-to-day lives and how to develop a trusting working-relationship with the child and family has not been explored prior to this research. Grounded theory methods supported the process of exploring the social processes of "building trust" whilst "working with" families in a vulnerable position. Nurses rely on rapport to be invited into a family's space to "work with" and support the re-establishment of the parenting role. The "stepping in and out" of an effective working-relationship with a family is reliant on trust. Nurses build trust by spending time to "be with", using chat to get to know each other, involving and supporting the family to parent a "different" child and reassuring and giving realistic hope to help the child and parents cope with their changed future.A substantive theory of the concept of "building trust to work with" has been developed using grounded theory methods. The theory has been conceptualized using the perspective of seven registered nurses working in paediatric acute care wards that admit children who have had a severe traumatic accident.

Conclusion. These data provide a clue that AT1 receptor blocker could effectively attenuate severe form of pancreatitis and its-associated systemic inflammation in experimental models of AP. The underlying mechanisms may be involved in Ang II-induced NADPH oxidase derived oxidative stress, particularly NFkappaB and ERK1/2-dependent CREB activation. The pro-inflammatory pathways would commonly converge to transcribe an array of genes such as IL-6, thus regulating the severity of pancreatitis and the onset of its complications. All these in vivo and in vitro data provide substantial evidence that Ang II is involved in AT1 receptor-mediated signaling cascade in regulating the pathogenesis of AP. The findings provide a new insight on potential application of AT 1 receptor blockade for a therapeutic approach in the management of AP. (Abstract shortened by UMI.) / Recent advance in basic research has revealed that the renin-angiotensin system (RAS) plays an important role in the pathogenesis of AP. In this regard, the present study aimed at investigating the effectiveness of RAS blockade in clinically relevant AP animal model and AP-associated systemic inflammation. More importantly, the underlying mechanistic pathways involved in angiotensin II (Ang II)-induced pro-inflammatory actions were elucidated using both in vivo and in vitro systems. / Results. Major components of RAS were up-regulated in obstructive pancreatitis model. Blockade of AT1 receptor attenuated pancreatic injury induced by the two models. Moreover, losartan could significantly ameliorate AP-associated systemic inflammation. Analysis of protein expression levels revealed that losartan treatment improved AP-associated elevation of NADPH oxidase p67 and p22 subunits. Double-immunostaining confirmed that expression of NADPH oxidase was localized to pancreatic acinar cells. AT1 receptor antagonism not only reduced oxidative stress but also suppressed nuclear factor kappaB (NFkappaB) activation, as evidenced by reversal effects on IkappaBbeta depletion, augmentation of phosphor NFkappaB p65, and enhanced nuclear kappaB binding activity. Blockade of AT1 receptor could also suppress the levels of kappaB-related protein expression, including intercellular adhesion molecule-1, cyclooxygenase-2, and IL-1. On the other hand, pancreatic mRNA and protein levels of IL-6 were enhanced by obstructive AP, which were antagonized by AT1 receptor blocker. Losartan treatment could reverse extracellular-regulated kinase (ERK) 1/2 and cAMP-responsive element binding protein (CREB) phosphorylation brought by obstructive AP. In vitro studies, exogenous application of Ang II induced ERK1/2 and CREB activation in AR42J cells. Concomitantly, IL-6 expression was augmented dose- and time-dependently in response to Ang II, which was reversed by treatment of AT1 receptor blocker (losartan) and ERK1/2 inhibitor (PD98059). Ang II induced NFkappaB activation was reversed by pre-treatment of AT1 receptor blocker and NADPH oxidase inhibitor but not ERK1/2 inhibitor in vitro. Moreover, Ang II-induced superoxide generation was detected. Treatment of antioxidant prevented Ang II-induced ERK1/2 activation. On top of these, in vitro experiments revealed that Ang II could sustain the activation of caerulein-induced NFkappaB and ERK1/2 in an AT1 receptor-mediated manner, but not secretagogue-induced hypersecretion. / Chan, Yuk Cheung. / Adviser: Po Siny Lzung. / Source: Dissertation Abstracts International, Volume: 70-06, Section: B, page: 3246. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 228-262). / Electronic reproduction.
