Anesthetic implications of infants with mandibular hypoplasia treated with mandibular distraction osteogenesis.
To document the incidence of difficult intubation following mandibular distraction osteogenesis (MDO) in children with severe mandibular hypoplasia. ⋯ In a select group of infants with severe upper airway obstruction who have failed nonsurgical airway interventions, mandibular distraction osteogenesis reduces the incidence of difficult mask ventilation and difficult intubation. We were not able to compare the improvement in airway management to a comparable group of PRS infants who did not undergo surgical intervention. The improvement in laryngeal view was most marked for infants with isolated PRS but no significant benefit was demonstrated in infants with TCS.

Laryngeal cleft is a rare congenital malformation that is being reported with increasing frequency. Diagnosis requires suspension microlaryngoscopy under general anesthesia during spontaneous respiration. Repair may be attempted by a minimally invasive endoscopic approach or open surgical repair. The authors report on their experience with total intravenous anesthesia (TIVA) and spontaneous ventilation without an endotracheal tube during suspension laryngoscopy and CO2 laser application for this specific surgical procedure. Of particular interest were the rate at which this technique failed and rescue techniques were employed and the ability to predict patients in whom this might occur. ⋯ The technique of TIVA with spontaneous respirations without an endotracheal tube is a safe and effective technique for laryngeal cleft repair. Although the potential for intraoperative adverse events may be high, the actual rate was very low. The need to convert to other techniques is not significant although the children who did require brief periods of jet ventilation or intubation tended to have reactive airway disease or chronic lung disease.

Following a propofol anesthetic, a 5-year-old girl with lower extremity spasticity seized and developed hypertriglyceridemia, hyperkalemia, and metabolic acidosis. A presumed diagnosis of propofol infusion syndrome (PRIS) was made, but further investigation revealed neonatal adrenoleukodystrophy. PRIS should be considered with this constellation of symptoms, but other neurometabolic disorders must always be ruled out.

Randomized Controlled TrialEffect of short-term propofol administration on pancreatic enzymes and lipid biochemistry in children between 1 month and 36 months.
Use of propofol in pediatric age group has been marred by reports of its adverse effects like hypertriglyceridemia and acute pancreatitis, although a causal relation has not yet been established. ⋯ We conclude that despite a small, transient increase in serum triglycerides and pancreatic enzymes, short-term propofol administration in recommended dosages in children of ASA status I and II aged between 1 month and 36 months does not produce any clinically significant effect on serum lipids and pancreatic enzymes.
