Does topical lidocaine before tracheal intubation attenuate airway responses in children? An observational audit.
The use of topical lidocaine, applied to the airways with various administration techniques, is common practice in pediatric anesthesia in many institutions. However, it remains unclear whether these practices achieve their intended goal of reducing the risk of perioperative respiratory adverse events (PRAE) in children undergoing elective endotracheal intubation without neuromuscular blockade (NMB). The relative frequency of PRAE (laryngospasm, coughing, desaturation <95%) associated with no use of topical airway lidocaine (TAL), with TAL sprayed directly onto the vocal cords, and TAL administered blindly into the pharynx was assessed. ⋯ The incidence of desaturation was higher in patients receiving TAL compared with children who did not. This association should perhaps be considered when contemplating the use of this technique.

Randomized Controlled Trial Comparative StudyComparison of size 2 i-gel supraglottic airway with LMA-ProSeal™ and LMA-Classic™ in spontaneously breathing children undergoing elective surgery.
We compared size 2 i-gel(®) (Intersurgical Inc.), a relatively new supraglottic airway device for use in spontaneously breathing anesthesized children with two different types of laryngeal mask airway-ProSeal™ laryngeal mask airway (PLMA) and Classic™ laryngeal mask airway (cLMA) for the ease of insertion, oropharyngeal sealing pressures (OSPs), and air leak. The hemodynamic effects on insertion of device and postoperative adverse effects were also noted. ⋯ Pediatric size 2 i-gel is easy to insert and provides higher OSP compared with same size PLMA and cLMA in spontaneously breathing children undergoing elective surgery. It may be a safe alternative to laryngeal mask airways in day care surgeries.

Ingestion of stimulant medications does not alter bispectral index or clinical depth of anesthesia at 1 MAC sevoflurane in children.
Children treated with stimulant medications for the behavioral management of attention deficit hyperactivity disorder (ADHD) may present for elective surgery. Stimulant medication is often continued until the morning of surgery to optimize perioperative behavior. It is unknown whether such stimulant drug ingestion can affect cerebral arousal and alter depth of anesthesia. A clinically relevant alteration in measured depth of anesthesia could form the basis for an evidence-based recommendation that children taking stimulant medications require a change in the amount of anesthetic delivered or that they require routine monitoring of depth of anesthesia. ⋯ Children taking stimulant medication for ADHD, and who ingest medication on the day of surgery, do not appear to have altered BIS or depth of anesthesia at 1 MAC of sevoflurane. These results do not support a recommendation for a change in anesthetic practice for children having ingested stimulants up to the day of surgery, either in terms of increasing the amount of anesthetic given or monitoring of depth.
