Randomized Controlled Trial
Does the prophylactic administration of magnesium sulphate to patients undergoing thoracotomy prevent postoperative supraventricular arrhythmias? A randomized controlled trial.
Supraventricular arrhythmias (SVA) are common after thoracic surgery and are associated with increased morbidity and mortality. This prospective, randomized, double-blind, placebo-controlled trial examined the effects of perioperative magnesium on the development of postoperative SVA. ⋯ Overall, prophylactic magnesium did not reduce the incidence of SVA in patients undergoing thoracotomy. However, it reduced the incidence of SVA in the high-risk cohort of patients undergoing pneumonectomy. (ISRCTN22028180.).

Candida species are a common cause of nosocomial bloodstream infection. Such infections commonly affect patients in the intensive care unit (ICU) and carry a high mortality. There are published guidelines for the management of fungal infections, but there are no data on the usual management of invasive Candida infections in UK ICUs. ⋯ Management of fungal infections is relatively consistent among responding units. However, recent developments in the field have not yet been incorporated into standard practice. Adherence to published guidelines could be improved, potentially reducing morbidity and mortality from these common infections.

Sympathetic block causes vasodilatation and increases in skin temperature (T(s)). However, the T(s) response after specific nerve blocking is unknown. In this study, we hypothesized that T(s) would increase after specific blocking of the nerve innervating that area. ⋯ Specific blocking of the ulnar and median nerve causes substantial increases in T(s) in specific areas of the hand. In contrast, the specific blocking of the musculocutaneous or radial nerve does not increase T(s). Further studies are needed to clarify if these findings can be used to objectively evaluate brachial plexus block success.

Review Meta Analysis Comparative Study
Single-dose intravenous paracetamol or propacetamol for prevention or treatment of postoperative pain: a systematic review and meta-analysis.
Paracetamol is the most commonly prescribed analgesic for the treatment of acute pain. The efficacy and safety of i.v. formulations of paracetamol is unclear. We performed a systematic search (multiple databases, bibliographies, any language, to May 2010) for single-dose, randomized, controlled clinical trials of propacetamol or i.v. paracetamol for acute postoperative pain in adults or children. ⋯ However, pain on infusion occurred more frequently in those receiving propacetamol compared with placebo (23% vs 1%). A single dose of either propacetamol or i.v. paracetamol provides around 4 h of effective analgesia for about 37% of patients with acute postoperative pain. Both formulations are associated with few AEs, although patients receiving propacetamol have a higher incidence of pain on infusion.

Randomized Controlled Trial
Pregabalin has an opioid-sparing effect in elderly patients after cardiac surgery: a randomized placebo-controlled trial.
In this prospective, randomized, double-blind, placebo-controlled study, we investigated the effect of pregabalin on oxycodone consumption, postoperative confusion, and pain in elderly cardiac surgery patients. ⋯ The administration of pregabalin reduced postoperative opioid consumption after cardiac surgery reduced the incidence of confusion on the first postoperative day and increased time to extubation when compared with placebo. Three months after operation, patients in the pregabalin group experienced less pain during movement.
