POCD in children

W Alan C Mutch, Renée M El-Gabalawy, M Ruth Graham
Evidence of anesthetic neurotoxicity is unequivocal when studied in animal models. These findings have translated poorly to the clinical domain when equated to postoperative delirium (POD) in adults and postoperative cognitive dysfunction (POCD) in either children or the elderly. In this perspective, we examine various reasons for the differences between animal modeling of neurotoxicity and the clinical situation of POD and POCD and make suggestions as to potential directions for ongoing research. We hypothesize that the animal anesthetic neurotoxicity models are limited, in part, due to failed scaling correction of physiological time...

BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

AIM: To improve the quality of anesthesia in school-age children by using intraoperative metabolic-mediated cerebroprotection to reduce the incidence of cognitive impairment after total intravenous anesthesia based on propofol. MATERIAL AND METHODS: A randomized, prospective, longitudinal clinical study was conducted, involving 60 school-age children operated under total intravenous anesthesia on the basis of propofol. Children were randomized into two equal groups...

OBJECTIVE: We studied the influence of Dexmedetomidine on cognitive function in children during the recovery period of general anesthesia. PATIENTS AND METHODS: Ninety-three children who underwent general anesthesia were selected and randomly divided into (1) the control group, (2) the dexmedetomidine group, and (3) the dezocine group. Fentanyl, propofol, and rocuronium were used in all patients to induce anesthesia, while sevoflurane inhalation and propofol were used to maintain anesthesia...

BACKGROUND: Mounting evidence indicates that children who experience abuse and neglect are prone to chronic diseases and premature mortality later in life. One mechanistic hypothesis for this phenomenon is that early life adversity alters the expression or functioning of the glucocorticoid receptor (GR) throughout the course of life and thereby increases sensitivity to inflammatory stimulation. An exaggerated pro-inflammatory response is generally considered to be a key cause of postoperative cognitive dysfunction (POCD)...

Due to the neurotoxicity effects of general anesthesia (GA) and sedatives found in animal studies, there is a general recommendation to avoid nonurgent surgical procedures requiring anesthesia in children younger than 3 years of age. The aim of this study was to determine the incidence of anesthesia-related postoperative cognitive dysfunction (POCD) on the first day (Day 1) and at 6 weeks after elective noncardiac surgery in school-age children.This was a prospective cohort study of 118 children undergoing GA and 126 age-matched controls of school children aged 5 to 12 years...

Accumulation of β-amyloid (Aβ) plaques is a pathological hallmark of Alzheimer disease. Aβ levels in animals and adults were reported to be associated with postoperative cognitive dysfunction (POCD). Our goal was to determine the plasma levels of Aβ in infants and young children after cardiac surgery with cardiopulmonary bypass (CPB).Forty-two infants and young children aged from 1 to 35 months undergoing cardiac surgery with general anesthetics were prospectively enrolled from January to June 2014 at a tertiary medical center...

BACKGROUND: Postoperative cognitive dysfunction (POCD) is well established in adults but has been underinvestigated in children. As day-case procedures are increasingly common, it is important to establish whether children suffer significant POCD. Pediatric POCD has been associated with several intravenous and inhalation anesthetics, but isoflurane has not been studied. As evidence indicates superior recovery after propofol, the study compared POCD after propofol or isoflurane anesthesia...

UNLABELLED: The aim of the study was to assess the possibility and effectiveness of hopaten acid use for early postoperative cognitive dysfunction correction in children of school age. MATERIALS AND METHODS: In compliance with inclusion and exclusion criteria, totally 40 children of school age (7-16 years old, ASA status I-II) with surgical pathology: (varicocele, cryptorchidism, inguinal hernia) were included A comperative assessment of neuropsychic status during pre - and postoperative are period in children, operated under propofol-fentanyl total intravenous anesthesia (TIVA) was conducted All patients were randomized to the control (without cepebroprotection 1st group, 20 children) and experimental (using cepebroprotection with hopaten acid within 1 month after the operation, 2nd group, 20 children) groups...

PURPOSE: The purpose of this structured, evidence-based, clinical update was to identify the best evidence comparing general and regional anesthesia and their influence on delirium or cognitive dysfunction (POCD) in the postoperative period. SOURCE: In June 2005 a structured search of MEDLINE from 1966 to present using OVID software was undertaken. Medical subject headings and textwords describing both delirium and POCD were employed. OVID's Therapy (sensitivity) algorithm was used to maximize the detection of randomized trials...
