Playing video clips during the inhaled induction of children undergoing ambulatory surgery is an effective method of reducing anxiety. Therefore, pediatric anesthesiologists may consider using video distraction as a useful, valid, alternative strategy for achieving a smooth transition to the anesthetized state.

Previous studies have suggested that desmopressin may reduce the bleeding diathesis that often complicates open-heart surgery. To pursue this question further, we performed a double-blind, randomized, placebo-controlled trial to determine whether the previously reported beneficial effect of desmopressin on hemostasis during complex cardiac surgery was applicable to all elective cardiac surgical procedures involving cardiopulmonary bypass. In 150 consecutive patients, most of whom underwent primary coronary-artery bypass grafting, we compared the effects of intravenous desmopressin (0.3 microgram per kilogram of body weight) with those of saline placebo on postoperative blood loss and the need to replace blood products. The median amount of blood lost within the first 24 hours after operation was similar in the desmopressin and placebo groups (865 vs. 738 ml; P = 0.26). The postoperative use of blood replacement products did not differ significantly between the groups (1025 ml [95 percent confidence interval, 300 to 4140 ml] in the desmopressin group and 860 ml [247 to 5346 ml] in the placebo group). Desmopressin is believed to exert its hemostatic effect by releasing von Willebrand factor. The level of ristocetin cofactor, a functional index of the level of von Willebrand factor, was increased approximately twofold from base line in both treatment groups 90 minutes and 24 hours after the administration of medication. Similarly, the levels of von Willebrand factor multimers increased uniformly in both groups. These findings may be consistent with a normal stress response of von Willebrand factor to major surgery and could explain our failure to detect a therapeutic effect of desmopressin. We conclude that the majority of patients who undergo elective cardiac surgery receive no hemostatic benefit from the use of desmopressin.

We report a case of difficult intubation in a child with Goldenhar syndrome and atypical plasma cholinesterase. Intubation attempts by direct laryngoscopy and the Trachlight were unsuccessful. The airway was ultimately secured using the pediatric GlideScope in conjunction with external laryngeal manipulation.

This study shows that adolescents having major jaw surgery are helped by the blood pressure-decreasing drug clonidine. This drug allows smaller doses of anesthetics, pain relievers, and blood pressure-decreasing drugs to be used; reduces changes in heart rate and blood pressure; and provides faster recovery from the anesthetic.

The aim of this prospective observational study was to determine if children undergoing bilateral myringotomy and tympanostomy tube insertion with a sevoflurane anesthetic plus intravenous propofol and ketorolac experienced a lower incidence of emergence agitation than those receiving a sevoflurane anesthetic alone. Duration of procedure, length of stay in post-anaesthesia care and level of nursing effort required to care for patients were also assessed. In this study, 49 children younger than 13 years of age received a sevoflurane anesthetic. Fifty-one percent of these patients also received a single injection of propofol 1 mg/kg and ketorolac 0.5 mg/kg at the end of the procedure. Patients were assessed for emergence agitation using the Pediatric Anesthesia Emergence Delirium scale in the post-anaesthesia care unit. Four children receiving a sevoflurane anesthetic alone experienced emergence agitation, while no children receiving propofol and ketorolac experienced emergence agitation (p = 0.05). The length of stay until discharge from the hospital was 6.98 min longer for patients receiving propofol and ketorolac but did not reach statistical significance (p = 0.23). Nurses reported greater ease in caring for patients receiving the propofol and ketorolac injection (recovery questionnaire score 4.50 vs. 3.75, p = 0.002). In this study, adding a single injection of intravenous propofol and ketorolac to the end of a brief sevoflurane anesthetic for bilateral myringotomy with tube insertion was associated with a lower incidence of emergence agitation without significantly increasing the time to discharge from the hospital.
