  • Anesthetic Management During Surgery for Tetralogy of Fallot With Pulmonary Atresia and Major Aortopulmonary Collateral Arteries WORLD JOURNAL FOR PEDIATRIC AND CONGENITAL HEART SURGERY Quinonez, Z. A., Downey, L., Abbasi, R. K., Kuan, C., Asija, R., McElhinney, D. B., Hanley, F. L., Mainwaring, R. D., Wise-Faberowski, L. 2018; 9 (2): 236?41

    Abstract

    Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collaterals (TOF/PA/MAPCAs) is a heterogeneous disease with varying degrees of severity, requiring complex anesthetic management. Our institution has adopted the approach of early complete repair with incorporation of all lung segments, extensive lobar and branch segmental pulmonary artery reconstruction, and ventricular septal defect closure. While the surgical management of TOF/PA/MAPCAs has been extensively described and varies depending on the institution, there is a paucity of literature on the anesthetic management for such procedures. Herein, we describe our anesthetic management based on our own institution's surgical approach at Lucile Packard Children's Hospital/Stanford University.

  • Effect of General Anesthesia in Infancy on Long-Term Recognition Memory in Humans and Rats NEUROPSYCHOPHARMACOLOGY Stratmann, G., Lee, J., Sall, J. W., Lee, B. H., Alvi, R. S., Shih, J., Rowe, A.

    Abstract

    Anesthesia in infancy impairs performance in recognition memory tasks in mammalian animals, but it is unknown if this occurs in humans. Successful recognition can be based on stimulus familiarity or recollection of event details. Several brain structures involved in recollection are affected by anesthesia-induced neurodegeneration in animals. Therefore, we hypothesized that anesthesia in infancy impairs recollection later in life in humans and rats. Twenty eight children ages 6-11 who had undergone a procedure requiring general anesthesia before age 1 were compared with 28 age- and gender-matched children who had not undergone anesthesia. Recollection and familiarity were assessed in an object recognition memory test using receiver operator characteristic analysis. In addition, IQ and Child Behavior Checklist scores were assessed. In parallel, thirty three 7-day-old rats were randomized to receive anesthesia or sham anesthesia. Over 10 months, recollection and familiarity were assessed using an odor recognition test. We found that anesthetized children had significantly lower recollection scores and were impaired at recollecting associative information compared with controls. Familiarity, IQ, and Child Behavior Checklist scores were not different between groups. In rats, anesthetized subjects had significantly lower recollection scores than controls while familiarity was unaffected. Rats that had undergone tissue injury during anesthesia had similar recollection indices as rats that had been anesthetized without tissue injury. These findings suggest that general anesthesia in infancy impairs recollection later in life in humans and rats. In rats, this effect is independent of underlying disease or tissue injury.

  • Anesthesia and the developing brain: relevance to the pediatric cardiac surgery. Brain sciences Wise-Faberowski, L., Quinonez, Z. A., Hammer, G. B. 2014; 4 (2): 295-310

    Abstract

    Anesthetic neurotoxicity has been a hot topic in anesthesia for the past decade. It is of special interest to pediatric anesthesiologists. A subgroup of children potentially at greater risk for anesthetic neurotoxicity, based on a prolonged anesthetic exposure early in development, are those children receiving anesthesia for surgical repair of congenital heart disease. These children have a known risk of neurologic deficit after cardiopulmonary bypass for surgical repair of congenital heart disease. Yet, the type of anesthesia used has not been considered as a potential etiology for their neurologic deficits. These children not only receive prolonged anesthetic exposure during surgical repair, but also receive repeated anesthetic exposures during a critical period of brain development. Their propensity to abnormal brain development, as a result of congenital heart disease, may modify their risk of anesthetic neurotoxicity. This review article provides an overview of anesthetic neurotoxicity from the perspective of a pediatric cardiac anesthesiologist and provides insight into basic science and clinical investigations as it relates to this unique group of children who have been studied over several decades for their risk of neurologic injury.

  • Anisocoria in a 10-month old girl in the immediate preoperative setting: can you proceed with surgery? Journal of biomedical research Quinonez, Z. A., Ravula, N. R. 2011; 25 (3): 224-226

    Abstract

    We report the case of a 10-month old girl with a significant past medical history who presented for elective surgery with a new-onset fixed, dilated pupil. We briefly review the diagnostic approach to such patients and provide guidelines for managing these patients in the immediate preoperative setting.
