Propofol pharmacokinetic and pharmacodynamic profile and its electroencephalographic interaction with remifentanil in children.
Propofol and remifentanil are commonly combined during total intravenous anesthesia. The impact of remifentanil in this relationship is poorly quantified in children. Derivation of an integrated pharmacokinetic and pharmacodynamic propofol model, containing remifentanil pharmacodynamic interaction information, enables propofol effect-site target-controlled infusion in children with a better prediction of its hypnotic effect when both drugs are combined. ⋯ We have developed an integrated propofol pharmacokinetic-pharmacodynamic model that can describe the pharmacodynamic interaction between propofol and remifentanil for BIS response. An additive interaction was supported by our modeling analysis.

Case ReportsPerioperative management of tracheocutaneous fistula closure in children: A review of 96 cases.
A tracheocutaneous fistula is a known complication following tracheostomy decannulation. Although surgical techniques for its repair are well described, there is no consensus about perioperative management and this procedure may generate significant airway and respiratory complications intraoperatively, and in the early postoperative period. We aimed to describe variations in perioperative management in tracheocutaneous fistula closure, estimate the incidence of early airway and respiratory complications, and identify any predisposing factors. ⋯ Perioperative care for children undergoing tracheocutaneous fistula closure was not standardized. Advocated tests such as preoperative "mini" sleep studies and "leak test" intraoperatively were not consistently performed. Intraoperative anesthetic complications were uncommon; however, major postoperative respiratory complications were 5%.

Comparative StudyA retrospective comparison of propofol to dexmedetomidine for pediatric magnetic resonance imaging sedation in patients with mucopolysaccharidosis type II.
Mucopolysaccharidosis type II patients are reported to have an elevated incidence of difficult airway. Propofol is a commonly used sedative for magnetic resonance imaging in pediatric patients, but patients who receive it may exhibit dose-dependent upper airway obstruction and respiratory depression. Dexmedetomidine also provides adequate procedural sedation with a relatively low risk of airway obstruction. Accordingly, we introduced the use of dexmedetomidine in our practice to reduce the risk of airway obstruction during magnetic resonance imaging procedures. ⋯ Dexmedetomidine provides an adequate level of sedation and is associated with lower rates of artificial airway interventions compared to propofol. Therefore, dexmedetomidine may offer advantages for preserving the native airway compared to propofol when administered during magnetic resonance imaging scans in patients with mucopolysaccharidosis type II.

Case ReportsMedical alert tattoos-A pinch of style along with patient safety.
The use of medical tattoos can potentially be life-saving. We present a 16-year-old patient who chose to tattoo a medical condition on her forearm. ⋯ To our knowledge, there are no published guidelines recommending an ideal location or symbology for a medical tattoo. Such guidelines would be useful to artists, as well as to medical personnel in emergencies if the patient has a tattoo.
