Review Meta Analysis
Goal-directed therapy in cardiac surgery: a systematic review and meta-analysis.
Perioperative mortality after cardiac surgery has decreased in recent years although postoperative morbidity is still significant. Although there is evidence that perioperative goal-directed haemodynamic therapy (GDT) may reduce surgical mortality and morbidity in non-cardiac surgical patients, the data are less clear after cardiac surgery. The objective of this review is to perform a meta-analysis on the effects of perioperative GDT on mortality, morbidity, and length of hospital stay in cardiac surgical patients. ⋯ The use of pre-emptive GDT in cardiac surgery reduces morbidity and hospital length of stay.

Review Meta Analysis
Do team processes really have an effect on clinical performance? A systematic literature review.
There is a growing literature on the relationship between team processes and clinical performance. The purpose of this review is to summarize these articles and examine the impact of team process behaviours on clinical performance. We conducted a literature search in five major databases. ⋯ The studies are highly diverse regarding the specific team process behaviours investigated and also regarding the methods used. However, they suggest that team process behaviours do influence clinical performance and that training results in increased performance. Future research should rely on existing theoretical frameworks, valid, and reliable methods to assess processes such as teamwork or coordination and focus on the development of adequate tools to assess process performance, linking them with outcomes in the clinical setting.

Role of therapeutic hypothermia in improving outcome after traumatic brain injury: a systematic review.
This systematic review delineates the effect of primary therapeutic hypothermia (PTH) (initiated on presentation of the patient) on both mortality and neurological outcome in patients with traumatic brain injury. The safety profile of the therapy is also assessed. A systematic search of the following databases was performed: MEDLINE, EMBASE, Zetoc database of conference proceedings, the Cochrane Database of Systematic Reviews, and the clinicaltrials.gov website, up to July 28, 2011. ⋯ Hypothermia was associated with cerebrovascular disturbances on rewarming and possibly with pneumonia in adult patients. Given the quality of the data currently available, no benefit of PTH on mortality or neurological morbidity could be identified. The therapy should therefore only be used within the confines of well-designed clinical trials.

Opioid-induced respiratory depression in paediatrics: a review of case reports.
Opioids remain the cornerstone of modern-day pain treatment, also in the paediatric population. Opioid treatment is potentially life-threatening, although there are no numbers available on the incidence of opioid-induced respiratory depression (OIRD) in paediatrics. To get an indication of specific patterns in the development/causes of OIRD, we searched PubMed (May 2012) for all available case reports on OIRD in paediatrics, including patients 12 yr of age or younger who developed OIRD from an opioid given to them for a medical indication or due to transfer of an opioid from their mother in the perinatal setting, requiring naloxone, tracheal intubation, and/or resuscitation. ⋯ In eight cases, OIRD was due to an iatrogenic overdose. Three distinct patterns in the remaining data set specifically related to OIRD include: (i) morphine administration in patients with renal impairment, causing accumulation of the active metabolite of morphine; (ii) codeine use in patients with CYP2D6 gene polymorphism associated with the ultra-rapid metabolizer phenotype, causing enhanced production of the morphine; and (iii) opioid use in patients after adenotonsillectomy for recurrent tonsillitis and/or obstructive sleep apnoea, where OIRD may be related to hypoxia-induced enhancement of OIRD. Despite the restrictions of this approach, our analysis does yield an important insight in the development of OIRD, with specific risk factors clearly present in the data.
