Randomized Controlled Trial Comparative Study
Intranasal dexmedetomidine premedication reduces the minimum alveolar concentration of sevoflurane for tracheal intubation in children: a randomized trial.
To determine the effects of dexmedetomidine premedication on the minimum alveolar concentration of sevoflurane for tracheal intubation (MACTI) in children. ⋯ Intranasal dexmedetomidine premedication produces a dose-dependent decrease in the concentration of sevoflurane needed for tracheal intubation in children.

To perform a frequency analysis of start minute digits (SMD) and end minute digits (EMD) taken from the electronic, computer-assisted, and manual anesthesia billing-record systems. ⋯ An electronic anesthesia record system, with automated time capture of events verified by the user, produces a more unified distribution of billing times than do more traditional methods of entering billing times.

Randomized Controlled Trial Comparative Study
Comparison of posterior and subcostal approaches to ultrasound-guided transverse abdominis plane block for postoperative analgesia in laparoscopic cholecystectomy.
To evaluate the effectiveness of subcostal TAP block and to compare its efficacy with that of posterior TAP block in decreasing postoperative pain in patients undergoing laparoscopic cholecystectomy during general anesthesia. ⋯ For incisions mainly involving the supra-umbilical region, subcostal TAP block may be a better alternative than the posterior approach for providing postoperative analgesia.

To perform a qualitative analysis of noncardiac patients who developed suspected intraoperative supraventricular tachycardia (SVT) during general anesthesia. ⋯ SVT during the intraoperative period in noncardiac pediatric patients was uncommon. When it occurred, it was not associated with clinically significant patient morbidity. For some patients, the anesthesia unmasked a predisposition for re-entrant SVT and those patients remained on maintenance antiarrhythmic therapy following discharge home.

Observational Study
Anesthesiologists' ability in calculating weight-based concentrations for pediatric drug infusions: an observational study.
To assess the ability of anesthesiologists to calculate weight-specific drug concentrations for continuous drug administration in children, and to evaluate the acceptance of an inhouse-developed, computer-based application for calculating drug infusions for pediatric cardiac surgery. ⋯ Anesthesiologists have difficulty calculating pediatric drug concentrations for continuous drug infusions. The correct calculations are time-consuming. Incorrect calculations may lead to dangerously high or low doses. A computer-based application to calculate drug concentrations was rated as very useful and user-friendly.
