Review Meta Analysis Comparative Study
Comparison of streamlined liner of the pharynx airway (SLIPA(™) ) and laryngeal mask airway: a systematic review and meta-analysis.
We performed a systematic review to compare the efficacy and safety of the streamlined liner of the pharynx airway and laryngeal mask airway used in adults during general anaesthesia. We included 14 studies with studies with 1273 patients in total. There was no evidence of a difference between the two devices in insertion success rate on the first attempt (13 studies, 1143 patients), insertion time (seven studies, 576 patients), ease of insertion (five studies, 466 patients), oropharyngeal leak pressure (eight studies, 771 patients) and the quality of the fibreoptic view of the larynx through the device (three studies, 281 patients). ⋯ Other adverse events were comparable. Subgroup analysis suggested that the insertion by novice users might be faster and more successful with the streamlined liner of the pharynx airway than the laryngeal mask airway; however, this was from only two studies and 186 patients. The method of size selection of the streamlined liner of the pharynx airway device might also affect the speed of insertion: choosing according to the width of the patient's thyroid cartilage, rather than height, may produce better results.

Review Meta Analysis
The effect of ondansetron on the efficacy of postoperative tramadol: a systematic review and meta-analysis of a drug interaction.
It is likely that there is an interaction between tramadol and ondansetron that decreases the early-postoperative analgesic efficacy of tramadol.

Review Meta Analysis
A systematic review and meta-analysis of perineural dexamethasone for peripheral nerve blocks.
Perineural dexamethasone may significantly increase the duration of analgesia after regional blockade, though without dose-response effect.

Review Meta Analysis
A systematic review and meta-regression analysis of mivacurium for tracheal intubation.
Higher dosing, waiting longer or combining with an opioid improve mivacurium intubating conditions, particularly in older patients.

Review Meta Analysis
The efficacy of lidocaine to prevent laryngospasm in children: a systematic review and meta-analysis.
The purpose of this meta-analysis was to determine the efficacy of lidocaine in preventing laryngospasm during general anaesthesia in children. An electronic search of six databases was conducted. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were adhered to. ⋯ Subgroup analysis revealed that both intravenous lidocaine (RR 0.34, 95% CI 0.14-0.82) and topical lidocaine (RR 0.42, 95% CI 0.22-0.80) lidocaine are effective in preventing laryngospasm. The results were not affected by studies with a high risk of bias. We conclude that, both topical and intravenous lidocaine are effective for preventing laryngospasm in children.
