Randomized Controlled TrialEffect of caudal block on sevoflurane requirement for lower limb surgery in children with cerebral palsy.
Caudal block is a widely used technique for providing perioperative pain management in children. In this randomized double-blinded study, we evaluated the effects of preoperative caudal block on sevoflurane requirements in children with cerebral palsy (CP) undergoing lower limb surgery while bispectral index (BIS) values were maintained between 45 and 55. ⋯ Caudal block effectively reduced sevoflurane requirements by 36% compared to general anesthesia alone in children with CP undergoing lower limb surgery while BIS values were maintained between 45 and 55.

Randomized Controlled Trial Comparative StudyA comparison of GlideScope(®) videolaryngoscopy and direct laryngoscopy for nasotracheal intubation in children.
The relative effectiveness of GlideScope(®) videolaryngoscopy (GV) for nasotracheal intubation in pediatric patients is unclear. The purpose of this study is to evaluate the usefulness of GV for nasotracheal intubation compared with direct laryngoscopy (DL) in pediatric patients. ⋯ GV can provide similar intubation performance characteristics compared with DL when used for nasotracheal intubation in pediatric patients. However, experience is needed to be skillful in the GV to acquire comparable TTI with DL.

Randomized Controlled TrialAn evaluation of intrathecal bupivacaine combined with intrathecal or intravenous clonidine in children undergoing orthopedic surgery: a randomized double-blinded study.
Propofol is a popular agent for providing intraoperative sedation in pediatric population during lumbar puncture and spinal anesthesia. Adjuvant-like clonidine is used increasingly in pediatric anesthesia to provide postoperative analgesia with a local anesthetic agent. The aim of this study was to assess the effects of intrathecal and intravenous clonidine on postoperative analgesia/sedation and intraoperative requirements of propofol after intrathecal bupivacaine for orthopedic surgery in children. ⋯ Intrathecal or intravenous clonidine similarly provided better postoperative analgesia and sedation and reduced the requirements of propofol. Only intrathecal clonidine prolonged the duration of sensory and motor blocks.

Retrospective audit of the air-Q intubating laryngeal airway as a conduit for tracheal intubation in pediatric patients with a difficult airway.
To assess the efficacy of the ILA as a conduit for tracheal intubation in pediatric patients with a difficult airway. ⋯ In a series of pediatric patients with difficult airways, the ILA was successfully used as a conduit for tracheal intubation in all patients. Visualization techniques may offer a greater degree of success in intubations through the ILA due to the potential for epiglottic down-folding in children.

The International Organization for Standardization (ISO) recently published an International Standard (ISO 7376:2009) which specifies illuminance levels and tests for illumination from hook-on type laryngoscopes used for intubation. A clinical study examining luminance for laryngoscopy found that 100 cd·m(-2) was the minimum level acceptable for laryngoscopy. The purpose of this study was to measure the quality of light from laryngoscopes available for use by anesthetists in an anesthetic department and compare them to the ISO illuminance standard and published minimum acceptable luminance limits. ⋯ Laryngoscope light should be regularly audited. Results from these audits can be used to retire or repair substandard laryngoscopes to maintain acceptable standards of laryngoscope light. Audit results produce tangible evidence that is useful when applying for capital expenditure. Light measurements are not easy to make. There needs to be a convenient device to reliably measure laryngoscope illumination.
