ReviewMobilisation strategies after hip fracture surgery in adults.
Post-operative care programmes after hip fracture surgery include strategies for mobilisation, such as early weight bearing, gait retraining and other physical therapy interventions. ⋯ There is insufficient evidence from randomised trials to determine the effects of more frequent or a more intensive programme of physiotherapy, quadriceps strengthening exercises, treadmill gait retraining, or neuromuscular stimulation after hip fracture surgery. There is also insufficient evidence to determine the effects of early weight bearing after the internal fixation of an intracapsular proximal femoral fracture.

ReviewDeep versus shallow suction of endotracheal tubes in ventilated neonates and young infants.
Mechanical ventilation is commonly used in Neonatal Intensive Care Units to assist breathing in a variety of conditions. Mechanical ventilation is achieved through the placement of an endotracheal tube (ETT) which is left in-situ. The ETT is suctioned to prevent a build-up of secretions and therefore blockage of the airway. Methods of suctioning the endotracheal tube vary according to institutional practice and the individual clinician performing the task. The depth of suctioning is one of these variables. The catheter may be passed to the tip of the ETT or beyond the tip into the trachea or bronchi to facilitate removal of secretions. However, trauma to the lower airways may result from the suction catheter being passed into the airway beyond the tip of the endotracheal tube. ⋯ There is no evidence from randomised controlled trials concerning the benefits or risks of deep versus shallow suctioning of endo-tracheal tubes in ventilated neonates and infants. Further high quality research would be required to conclusively establish whether there are any benefits to deep or shallow suctioning. However, as it may be considered unethical to conduct a trial of deep suctioning given anecdotal evidence regarding possible damage to the airway, it is proposed that a randomised controlled trial comparing deep with shallow suctioning may be considered in a NICU where the standard practice includes a deep suctioning technique.

ReviewSupplemental oxygen for the treatment of prethreshold retinopathy of prematurity.
Oxygen has long been implicated in the pathogenesis of retinopathy of prematurity (ROP) and is rigorously monitored in today's neonatal intensive care units. Recent research using a feline model has shown an improvement in ROP outcome of kittens treated with supplemental oxygen. Current treatment for ROP by retinal ablation is not without complications so a non-invasive method of treatment is preferred. The possible effects of long term oxygen supplementation on chronic lung disease, length of hospital stay and growth and development are, however, unknown. ⋯ The results of this systematic review do not show a statistically significant reduction in the rate of progression to threshold ROP with supplemental oxygen treatment, but reveal increased adverse pulmonary sequelae with higher oxygen targeting in this group of preterm infants. Future research needs to be directed towards the question of whether infants without plus disease are more likely to respond to supplemental oxygen therapy than those with plus disease.

ReviewInterventions for preventing oral mucositis for patients with cancer receiving treatment.
Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). ⋯ Several of the interventions were found to have some benefit at preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types hat benefits may be specific for certain cancer types and treatment. There is a need for well designed and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

Review Meta AnalysisGauze and tape and transparent polyurethane dressings for central venous catheters.
Central venous catheters facilitate venous access, allowing the intravenous administration of complex drug treatments, blood products and nutritional support, without the trauma associated with repeated venepuncture. However, central venous catheters are associated with a risk of infection. Some studies have indicated that the type of dressing used for central venous catheters may affect the risk of infection. Gauze and tape or transparent polyurethane film dressings such as Tegaderm, Opsite or Opsite IV3000 are the most common types of dressing used to secure central venous catheters. Currently, it is not clear which type of dressing is the most appropriate. ⋯ There is a high level of uncertainty regarding the risk of infection with the central venous catheter dressings identified in this review. Therefore, at this stage it appears that the choice of dressing for central venous catheters can be based on patient preference. To identify the most appropriate central venous catheter dressings, further research is necessary. It is paramount that any future studies investigating this issue must be rigorously performed randomised controlled trials.
