Abstract: This systematic review was conducted by the New Zealand Centre for Evidence Based Nursing, a collaborating centre of The Joanna Briggs Institute for Evidence Based Nursing and Midwifery. The aim was to present the best available evidence on interventions, which are effective in preventing or reducing the prevalence of complications associated with suctioning, in hospitalised adult patients with an artificial airway who are breathing spontaneously or are artificially ventilated and who require suctioning. The specific questions addressed were as follows: Which methods of suctioning reduce the prevalence of mucosal trauma or mucosal dysfunction, and promote the removal of respiratory secretions? Which techniques or methods are effective in reducing the occurrence of suctioning -induced hypoxaemia, during or following the suctioning procedure? Which techniques or methods are effective in minimising the haemodynamic or pulmonary complications associated with the suctioning procedure?

Abstract: This report presents an evaluation of the implementation of a best practice information sheet related to tracheal suctioning of adults with an artificial airway. The Centre for Evidence-Based Nursing Aotearoa, based in Auckland, conducted a systematic review of the evidence and produced the best practice information sheet. A survey of 105 nurses was conducted at three sites, in New Zealand and Australia. Using a before/after design, data were collected at the time of release of the information sheet and then approximately 12 months later. The study suggests a trend towards a modest uptake of best practice recommendations into nursing practice demonstrated by some behavioural changes within a 12-month period in the context of an implementation plan and the best practice information sheet.

Abstract: This paper explores the relationship between evidence, decision tools, and the effectiveness of the nursing contribution to health services. It examines a continuum of decision-making within the international trend of the Effectiveness Movement, drawing on international literature and local experience. It draws on the concept of explicit evidence-based decision-making, the guideline development movement as exemplified through the New Zealand Guidelines Group, information technology in decision support, and the challenges of an evidential approach to nursing. This article is based on a paper given at 'The Pride and Passion of Professional Nursing Practice' College of Nurses' Aotearoa (NZ) Conference, Rotorua, 8-9 October 1998.

Abstract: This article overviews the use of hyperbaric oxygen treatment in New Zealand primarily for chronic wounds, those who have had radiation therapy and those who are having or who have had head and neck surgery. In New Zealand there are just three hyperbaric oxygen treatment units: The Devonport Naval Base and The Oxygen Therapy Clinic, both in Auckland; and the Hyperbaric Medicine Unit in Christchurch; thus access to this treatment is limited.

Abstract: The objective of this meta-analysis was to assess the effectiveness of pentoxifylline as an adjunct to compression bandaging in the treatment of venous leg ulcers. The CENTRAL registers of the Cochrane Peripheral Vascular Diseases and Wounds Groups were searched – each register is routinely updated by extensive searches of electronic databases, handsearching of relevant journals and conference proceedings, and contact with product companies and experts in the field. The drug's manufacturer was contacted and the references of review articles and all obtained trials were scrutinised for further citations. Randomised controlled trials published in any language comparing pentoxifylline and compression with placebo in adult participants with venous ulceration were included. Trials must have reported a meaningful objective outcome (rates of healing, proportions healed, time to healing). Details from eligible trials (independently selected by two reviewers) were extracted and summarised by one reviewer. A second reviewer independently verified extracted data. Eleven clinical trials were identified. Five trials compared pentoxifylline with placebo (compression standard therapy). Six trials were excluded. Pentoxifylline and compression was more effective than placebo and compression (RR 1.30, 95% C1 1.10-1.54) and was robust to sensitivity analyses. The greater number of adverse effects (46 reports) occurred in the pentoxifylline group, although this was not significant (RR 1.12, 95% C1 0.77-1.62); 34 percent of adverse effects were gastro-intestinal. Seven of 21 reported withdrawals were for adverse effects. In conclusion, pentoxifylline appears an effective adjunct to compression bandaging in the treatment of venous ulcers. The absence of cost-effectiveness data suggests it not be employed as a routine adjunct, but it could be considered as for those patients not responding to compression therapy alone. The majority of adverse effects are likely to be tolerated by patients.

Abstract: The author provides a review of current protocols and presents new ways to manage the care of patients undergoing total joint arthroplasty, hip and knee replacement surgery.

Abstract: The author presents a review of evidence on the prophylactic use of paracetamol prior to infant and child immunisation. The research was prompted when the Otago District Health Board was planning its Meningococcal B strategy. The evidence suggests that it was appropriate when the whole cell pertussis vaccine was used, but it was not recommended since the introduction of better vaccines such as acellular pertussis with fewer antigens and fewer side effects. Paracetamol may still be given orally to treat pain and fever that occasionally follows vaccination. Paracetamol pharmacology is presented, along with alternatives to paracetamol.
