Review Meta AnalysisRegional (spinal, epidural, caudal) versus general anaesthesia in preterm infants undergoing inguinal herniorrhaphy in early infancy.
With improvements in neonatal intensive care, more premature infants are surviving the neonatal period. With this increase, more are presenting for surgery in early infancy. Of predominance in this period is the repair of inguinal herniae, appearing in 38% of infants whose birth weight is between 751g and 1000g. Most postoperative studies show that approximately 20% to 30% of otherwise healthy former preterm infants having inguinal herniorrhaphy under general anaesthesia have one or more apnoeas in the postoperative period. Regional anaesthesia might reduce postoperative apnoea in this population. ⋯ There is no reliable evidence from the trials reviewed concerning the effect of spinal as compared to general anaesthesia on the incidence of post-operative apnoea, bradycardia, or oxygen desaturation in ex-preterm infants undergoing herniorrhaphy. The estimates of effect in this review are based on a total population of only 108 patients or fewer.A large well designed randomised controlled trial is needed to determine if spinal anaesthesia reduces post-operative apnoea in ex-preterm infants not pretreated with sedatives. Adequate blinding, follow up and intention to treat analysis are required.

Review Meta AnalysisNon-invasive positive pressure ventilation for treatment of respiratory failure due to exacerbations of chronic obstructive pulmonary disease.
Non-invasive positive pressure ventilation (NPPV) is being used increasingly in the management of patients admitted to hospital with acute respiratory failure secondary to an exacerbation of chronic obstructive pulmonary disease (COPD). ⋯ Data from good quality randomised controlled trials permit NPPV to be recommended as the first line intervention, coupled with usual medical care, in all suitable patients with respiratory failure secondary to an acute exacerbation of COPD. A trial of NPPV should be considered early in the course of respiratory failure, and before severe acidosis ensures, as a means of avoiding endotracheal intubation, reducing mortality and treatment failure.

Review Meta AnalysisCell salvage for minimising perioperative allogeneic blood transfusion.
Concerns regarding the safety of transfused blood, have prompted reconsideration of the use of allogeneic (blood from an unrelated donor) red blood cell (RBC) transfusion, and a range of techniques to minimise transfusion requirements. ⋯ The results suggest cell salvage is efficacious in reducing the need for allogeneic red cell transfusion in adult elective surgery. However, the methodological quality of trials was poor. As the trials were unblinded and lacked adequate concealment of treatment allocation, transfusion practices may have been influenced by knowledge of the patient's treatment status biasing the results in favour of cell salvage.

Review Meta AnalysisEtanercept for the treatment of rheumatoid arthritis.
Etanercept is a soluble tumour necrosis factor alpha-receptor DMARD for the treatment of rheumatoid arthritis (RA). ⋯ Etanercept 25 mg SC twice weekly was more efficacious than control treatment for ACR 20, 50 and 70 at 6 months, and over 12 months it slowed joint damage.

Review Meta AnalysisEpidural analgesia for pain relief following hip or knee replacement.
Hip and knee replacement are common operative procedures to improve mobility and quality of life. Adequate pain relief is essential in the postoperative period to enable ambulation and initiation of physiotherapy. Lumbar epidural analgesia is a common modality for pain relief following these procedures. However, there is no systematic review of the evidence comparing the efficacy of epidural analgesia with other postoperative analgesic modalities. As the use of epidural analgesia may delay the initiation of anticoagulant thromboprophylaxis due to the potential risk of epidural hematoma, a synthesis of the evidence is necessary to determine whether or not alternative analgesic modalities are worse, equivalent, or better than epidural analgesia. ⋯ Epidural analgesia may be useful for postoperative pain relief following major lower limb joint replacements. However, the benefits may be limited to the early (four to six hours) postoperative period. An epidural infusion of local anesthetic or local anesthetic-narcotic mixture may be better than epidural narcotic alone. The magnitude of pain relief must be weighed against the frequency of adverse events. The current evidence is insufficient to draw conclusions on the frequency of rare complications from epidural analgesia, postoperative morbidity or mortality, functional outcomes, or length of hospital stay.
