Randomized Controlled Trial Observational StudyComparison of effects of volatile and intravenous anesthetics on pupillary function during general anesthesia in children: A prospective observational study.
The light reflex, which reflects central nervous system dysfunction, can also be affected by anesthetic agents. ⋯ The Neurological Pupil index value in pediatric patients under general anesthesia is affected by the anesthetic agent used; this factor requires consideration in evaluations of the Neurological Pupil index during general anesthesia.

Perioperative hypertension and anesthetic management in patients undergoing resection of neuroblastoma.
Neuroblastoma is the most common extracranial pediatric tumor, accounting for 5-8% of all childhood cancers. Neuroblastomas arise from catecholamine-secreting neural crest cells and their metabolites, vanillylmandelic acid and homovanillic acid, that are readily detected in urine. Although rarely seen in clinical practice, case reports exist documenting severe intraoperative hypertension. However, data on the incidence of intraoperative hypertension are lacking. ⋯ Intraoperative hypertension in patients with neuroblastoma remains a relatively uncommon occurrence; however, it does occur at a frequency higher than previously described. While intraoperative hypertension is associated with an increased use of antihypertensive medications in the operating room, it is not associated with adverse perioperative outcomes.

Observational StudyAlpha-1-acid glycoprotein and its potential impact on local anesthetic dose in neonates.
Alpha-1-acid glycoprotein is an acute-phase protein with a high affinity for amide local anesthetics. Compared to adults, neonates have lower concentrations of this glycoprotein in plasma, and are therefore at higher risk of developing local anesthetic toxicity. Alpha-1-acid glycoprotein concentrations rise in adults after surgery as a response to stress as well as in inflammatory conditions. Previous studies have shown that concentrations of alpha-1-acid-glycoprotein in neonates vary postpartum, influenced by gestational age and mode of delivery. ⋯ Alpha-1-acid-glycoprotein concentrations increase in neonates as a response to surgery regardless of gestational age, sex, or mode of delivery.
