Review Meta Analysis
Benzydamine hydrochloride on postoperative sore throat: a meta-analysis of randomized controlled trials.
Sore throat is a common postoperative complaint. The etiology of postoperative sore throat (POST) is considered the result of damage to airway mucosa after insertion of a laryngeal mask airway device or endotracheal tube. This paper proposes benzydamine hydrochloride (BH), a topical nonsteroidal anti-inflammatory drug (NSAID) with additional analgesic and local anesthetic properties, for POST prevention. ⋯ Our results indicate that the incidence of POST can be significantly reduced by prophylactic BH topical application to the oral cavity or airway devices. Further RCTs are required to overcome the limitations of heterogeneity and to determine the optimal dosage and application of BH for managing POST.

Meta Analysis Comparative Study
The effect of low concentrations versus high concentrations of local anesthetics for labour analgesia on obstetric and anesthetic outcomes: a meta-analysis.
The influence that different concentrations of labour epidural local anesthetic have on assisted vaginal delivery (AVD) and many obstetric outcomes and side effects is uncertain. The purpose of this meta-analysis was to determine whether local anesthetics utilized at low concentrations (LCs) during labour are associated with a decreased incidence of AVD when compared with high concentrations (HCs). ⋯ When compared with HCs of local anesthetics, the use of LCs for labour epidural analgesia reduces the incidence of AVD. This may be due to a reduction in the amount of local anesthetic used and the subsequent decrease in motor blockade. We therefore recommend the use of LCs of local anesthetics for epidural analgesia to optimize obstetric outcome.

Meta Analysis Comparative Study
Cerebral monitors versus regional anesthesia to detect cerebral ischemia in patients undergoing carotid endarterectomy: a meta-analysis.
The aim of this meta-analysis is to compare the ability of different types of brain monitoring systems vs clinical monitoring of the brain function to detect cerebral ischemia during cross-clamping of the carotid artery under regional anesthesia. ⋯ A combination of stump pressure and either TCD or EEG appears to deliver the best results for detecting brain ischemia during carotid artery cross-clamping. Electroencephalography should be used with a high number of channels.

Review Meta Analysis Historical Article
Should intraoperative cell-salvaged blood be used in patients with suspected or known malignancy?
Intraoperative cell salvage (ICS) is used as an alternative to allogeneic blood transfusion in an attempt to avoid or minimize the risks associated with allogeneic blood. Intraoperative cell salvage is generally avoided in surgeries where malignancy is confirmed or suspected due to concern for potential metastasis or cancer recurrence. The application of post-processing methods for ICS is hypothesized to eliminate this potential risk. The purpose of this narrative review is to examine the in vitro experimental evidence as it pertains to the removal of tumour cells from ICS blood and to review the clinical studies where ICS blood has been used in patients with malignancy. ⋯ Transfusion of autologous blood harvested via ICS should be considered a viable option for reduction or avoidance of allogeneic product during many oncologic surgeries and may be a lifesaving option for those patients who refuse allogeneic blood products.

Transversus abdominis plane block for analgesia after Cesarean delivery: a systematic review and meta-analysis.
In patients not receiving intrathecal morphine, TAP block after caesarean section reduced opioid use at 6, 12 and 24 hours, along with nausea at 12h.
