Effect of Inhaled Sevoflurane on Pediatric Cerebrospinal Fluid Pressure During Lumbar Puncture; Implications for Intracranial Hypertension.

To determine influence of sevoflurane on changes in cerebrospinal fluid pressure in children presenting for lumbar puncture. Cerebrospinal fluid pressure, end tidal carbon dioxide, and end tidal sevoflurane concentration measurements were obtained at 2-minute intervals for a total of 10 minutes (T0 to T5). Because of concerns regarding patient safety and comfort, the study measurements were completed at the end of the lumbar procedure, starting with the closing pressure and when sevoflurane was stopped.

Pain management following myringotomy and tube placement: intranasal dexmedetomidine versus intranasal fentanyl.

Purpose: Despite the brevity of the procedure, bilateral myringotomy and tympanostomy tube placement (BMT) can result in significant postoperative pain and discomfort. As the procedure is frequently performed without intravenous access, non-parenteral routes of administration are frequently used for analgesia. The current study prospectively compares the efficacy of intranasal (IN) dexmedetomidine with IN fentanyl for children undergoing BMT.

The effects of oral ondansetron disintegrating tablets for prevention of at-home emesis in pediatric patients after ear-nose-throat surgery.

Background: Tonsillectomy and adenoidectomy are associated with a frequent incidence of vomiting, both in the hospital and at home. We evaluated the effects of oral ondansetron disintegrating tablets (ODT) on the incidence of at-home emesis in children undergoing tonsillectomy with and without adenoidectomy and with and without bilateral myringotomy and tube insertion.

Methods: All patients underwent inhaled mask induction with nitrous oxide, oxygen, and sevoflurane.

Cardiac arrest under anesthesia in a pediatric patient with Williams syndrome: a case report.

Serial cardiac arrests occurred during the induction of a 3-year-old boy for elective 1-sided orchiopexy surgery and evaluation under anesthesia of previously placed ear tympanoplasty tubes. The child's history included Williams syndrome along with hypercalcemia and mild supravalvular aortic stenosis. The initial arrests included significant ST wave changes along with profound brodycardia, hypotension, and pulseless electrical activity requiring full resuscitation twice.

Fentanyl and alfentanil plasma protein binding in preterm and term neonates.

The effects of gestational age (GA) and plasma protein concentrations on the plasma protein binding of fentanyl and alfentanil were studied in preterm and term neonates. Binding experiments were performed using split-cell equilibrium dialysis. Fentanyl and alfentanil concentrations were measured using specific radioimmunoassay, and the proteins albumin and alpha-1-acid glycoprotein (AAG) were measured using radial immunodiffusion assays.
