Review Meta AnalysisDressings for the prevention of surgical site infection.
Surgical wounds (incisions) heal by primary intention when the wound edges are brought together and secured - often with sutures, staples, clips or glue. Wound dressings, usually applied after wound closure, provide physical support, protection from bacterial contamination and absorb exudate. Surgical site infection (SSI) is a common complication of surgical wounds that may delay healing. ⋯ At present, there is insufficient evidence as to whether covering surgical wounds healing by primary intention with wound dressings reduces the risk of SSI or whether any particular wound dressing is more effective than others in reducing the rates of SSI, improving scarring, pain control, patient acceptability or ease of dressing removal. Most trials in this review were small and at high or unclear risk of bias. However, based on the current evidence, we conclude that decisions on wound dressing should be based on dressing costs and the symptom management properties offered by each dressing type e.g. exudate management.

Review Meta AnalysisPulp treatment for extensive decay in primary teeth.
In children, dental caries is among the most prevalent chronic diseases worldwide. Pulp interventions are indicated for extensive tooth decay. Depending on the severity of the disease, three pulp treatment techniques are available: direct pulp capping, pulpotomy and pulpectomy. After treatment, the cavity is filled with a medicament.This is an update of a Cochrane review first published in 2003. The previous review found insufficient evidence regarding the relative efficacy of these interventions, combining one pulp treatment technique and one medicament. ⋯ We found no evidence to identify one superior pulpotomy medicament and technique clearly. Two medicaments may be preferable: MTA or FS. The cost of MTA may preclude its clinical use and therefore FS could be used in such situations. Regarding other comparisons for pulpectomies or direct pulp capping, the small numbers of studies undertaking the same comparison limits any interpretation.

Review Meta AnalysisIncentive spirometry for prevention of postoperative pulmonary complications in upper abdominal surgery.
This is an update of a Cochrane Review first published in The Cochrane Library 2008, Issue 3.Upper abdominal surgical procedures are associated with a high risk of postoperative pulmonary complications. The risk and severity of postoperative pulmonary complications can be reduced by the judicious use of therapeutic manoeuvres that increase lung volume. Our objective was to assess the effect of incentive spirometry compared to no therapy or physiotherapy, including coughing and deep breathing, on all-cause postoperative pulmonary complications and mortality in adult patients admitted to hospital for upper abdominal surgery. ⋯ There is low quality evidence regarding the lack of effectiveness of incentive spirometry for prevention of postoperative pulmonary complications in patients after upper abdominal surgery. This review underlines the urgent need to conduct well-designed trials in this field. There is a case for large RCTs with high methodological rigour in order to define any benefit from the use of incentive spirometry regarding mortality.

Below knee amputation (BKA) may be necessary in patients with advanced critical limb ischaemia or diabetic foot sepsis in whom no other treatment option is available. There is no consensus as to which surgical technique achieves the maximum rehabilitation potential. This is the third update of the review first published in 2004. ⋯ There is no evidence to show a benefit of one type of incision over another. However, in the presence of wet gangrene a two-stage procedure leads to better primary stump healing compared to a one-stage procedure. The choice of amputation technique can, therefore, be a matter of surgeon preference taking into account factors such as previous experience of a particular technique, the extent of non-viable tissue, and the location of pre-existing surgical scars.
