Safe and efficacious modalities of perioperative analgesia are essential for enhanced recovery after surgery. Truncal nerve blocks are one potential adjunct for analgesia of the abdominal wall, and in recent years their popularity has increased. Transversus abdominis plane block (TAPB) and rectus sheath block (RSB) have been shown to reduce morphine consumption and improve pain relief after abdominal surgery. These blocks typically require large volumes of local anaesthetic (LA). We aimed to synthesize studies evaluating systemic concentrations of LA after perioperative TAP and RSB to enhance our understanding of systemic LA absorption and the risk of systemic toxicity. ⋯ Local anaesthetic in TAPB and RSB can lead to detectable systemic concentrations that exceed commonly accepted thresholds of LA systemic toxicity. Our study highlights that these techniques are relatively safe with regard to LA systemic toxicity.

There are increasing numbers of videolaryngoscopes marketed and increasing interest in the technology. The Difficult Airway Society's 2015 guidelines recommend that videolaryngoscopes should be immediately available at all times and that all anaesthetists should be trained and skilled in their use. ⋯ Videolaryngoscopy is available in most hospitals' main operating departments, but in fewer than half of other locations. There is marked variation in device, methods of introduction, usage, and clinical adoption. Most hospitals need to change practice to comply with current guidelines. Selection and implementation vary widely.
