Review Meta Analysis
The role of venous blood gas in the Emergency Department: a systematic review and meta-analysis.
The aim of this study is to provide a systematic review of the literature reporting agreement between arterial and venous pH, partial pressure of carbon dioxide (PCO2), bicarbonate (HCO3⁻), base excess and lactate; and to perform a meta-analysis of the differences. Medline and Embase searches using Eduserv Athens from 1950 to present were conducted using the terms 'VBG', 'ABG', 'arterial', 'venous', 'blood', 'gas', 'lactate', 'emergency' and 'department'. References of the published papers were hand searched and full-text versions of those deemed helpful to the question were obtained. ⋯ Arteriovenous agreement for PCO2 is poor and PvCO2 cannot be relied upon as an absolute representation of PaCO2. However, normal peripheral PvCO2 has a good negative predictive value for normal arterial PCO2, and a normal PvCO2 can be used as a screen to exclude hypercapnic respiratory disease. There may be a poor agreement between arterial and venous lactate at abnormal values; however, if the venous lactate is normal, it is likely the arterial values of this parameter will also be normal.

Meta Analysis
The use of intravenous magnesium sulphate for acute migraine: meta-analysis of randomized controlled trials.
The objective of this study was to assess the efficacy and tolerability of intravenous magnesium for the treatment of acute migraine in adults. ⋯ The meta-analyses have failed to demonstrate a beneficial effect of intravenous magnesium in terms of reduction in pain relief in acute migraine in adults, showed no benefit in terms of the need for rescue medication and in fact have shown that patients treated with magnesium were significantly more likely to report side-effects/adverse events.

Review Meta Analysis
Transcutaneous electrical nerve stimulation for relieving acute pain in the prehospital setting: a systematic review and meta-analysis of randomized-controlled trials.
Although medics in many services are equipped with pharmacological analgesia, legislative or logistical restrictions in some systems result in the need to rely on nonpharmacological avenues for the management of acute pain. Transcutaneous electrical nerve stimulation (TENS) has been proposed as an alternative to analgesic medication that could be feasible and effective in the prehospital setting. The aim of this systematic review was to determine the effectiveness and safety of TENS when administered by medics to patients with acute pain in the prehospital setting. ⋯ TENS was also effective in reducing acute anxiety secondary to pain. No safety risks were identified. When administered by medics in the prehospital setting to patients with acute pain, TENS appears to be an effective and safe nonpharmacological analgesic modality that should be considered by emergency medical services organizations in which pharmacological pain management is restricted or unavailable.

Review Meta Analysis
Adverse outcomes in older adults attending emergency department: systematic review and meta-analysis of the Triage Risk Stratification Tool.
The objective of this study was to assess the predictive ability of the Triage Risk Stratification Tool (TRST) in identifying older adults at risk of adverse outcomes [return to emergency department (ED), hospitalization, or a composite outcome] within 30 and 120 days following discharge from ED. A systematic search was conducted to identify studies validating the TRST in older adults aged at least 65 years discharged from ED. The methodological quality of selected studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies tool. ⋯ There was little heterogeneity across studies. In conclusion, the TRST is limited in its ability to discriminate between older adults with or without an adverse outcome following discharge from ED. The low levels of heterogeneity gives us confidence that the pooled estimates reflect the predictive ability of the TRST in clinical practice.

Withholding administration of narcotic analgesia in patients with acute abdominal pain for fear of masking pathology is still pervasive in current medical practice. We reviewed all the prospective trials that investigated the safety, adverse affects, and ultimate outcome in patients with acute abdominal pain receiving narcotic analgesia within the emergency department (ED). No adverse outcomes or delays in diagnosis could be attributed to the administration of analgesia. Based on this research, we propose that it is safe and humane to administer narcotic pain relief to patients presenting to the ED with acute abdominal pain provided no contraindications exist.
