Effects of sevoflurane on the expression of tau protein mRNA and Ser396/404 site in the hippocampus of developing rat brain.
General anesthesia induces a transient hyperphosphorylation of tau protein that is associated with neurotoxicity in neonatal rats, but the mechanism remains unknown. The current study sought to investigate the effects of sevoflurane on the levels of tau phosphorylation at phosphor-Ser396/404 and total tau mRNA in the hippocampus of neonatal rats. ⋯ In rat hippocampus, sevoflurane was associated with microtubular disarray as well as increased levels of tau mRNA and excessive phosphorylation of tau protein at Ser396 and Ser404. This implicates that sevoflurane may induce neurotoxicity.

Skin temperature over the carotid artery provides an accurate noninvasive estimation of core temperature in infants and young children during general anesthesia.
The accurate measurement of core temperature is an essential aspect of intraoperative management in children. Invasive measurement sites are accurate but carry some health risks and cannot be used in certain patients. An accurate form of noninvasive thermometry is therefore needed. Our aim was to develop, and subsequently validate, separate models for estimating core temperature using different skin temperatures with an individualized correction factor. ⋯ Skin temperature over the carotid artery, with a simple correction factor of +0.52°C, provides a viable noninvasive estimate of Tnaso in young children during elective surgery with a general anesthetic.

Randomized Controlled TrialPostoperative emergence delirium in pediatric patients undergoing cataract surgery - a comparison of desflurane and sevoflurane.
Desflurane and sevoflurane are associated with postoperative emergence delirium (ED) in children. The study aimed to compare the use of desflurane and sevoflurane to determine the postoperative ED in children undergoing cataract surgery using the validated Pediatric Anesthesia Emergence Delirium (PAED) scale. ⋯ Emergence delirium (ED) after desflurane and sevoflurane anesthesia was comparable using a validated PAED scale in pediatric cataract surgery. There was no correlation between preoperative anxiety and ED in these children; however, children with higher pain scores were more likely to have a higher ED.

Laryngeal view and temperature measurements while using the perilaryngeal airway (Cobra-PLUS™) in children.
The Cobra-PLUS™ perilaryngeal airway (CP) is a modification of the Cobra perilaryngeal airway. It has a distal curve for easier placement and a thermistor on the pharyngeal cuff. We assessed the orientation of the larynx to the CP and compared temperatures measured using CP to temporal arterial (TA) and infrared tympanic (T) thermometers. ⋯ The CP has a better orientation to the larynx compared with its previous version. It may be used to reliably trend intraoperative temperatures.
