Multicenter Study Comparative StudyA national survey of the anesthetic management of tonsillectomy surgery in children.
Tonsillectomy in children is a common procedure; however, there appears to be a significant degree of variability in anesthetic management. Thus far, there has been no large national survey looking at the perioperative care of these children. ⋯ Whilst there is individual variability in the management of these cases, the majority of anesthetists prefer the intravenous route for induction of anesthesia, after application of topical anesthetic cream. It is routine practice to intubate the trachea, administer paracetamol, NSAIDs, strong opiates and antiemetics.

A left paraglossal approach for oral intubation in children scheduled for bilateral orofacial cleft reconstruction surgery--a prospective observational study.
Children with orofacial cleft defects are expected to have difficult airways. Conventional midline laryngoscopic approach of oral intubation can lead to iatrogenic tissue trauma. In this study, we evaluated the feasibility of left paraglossal laryngoscopy as a primary technique for airway management in these children. ⋯ Keeping in mind midline tissue support loss in cleft deformities, we propose routine use of left paraglossal laryngoscopic approach for intubating children with uncorrected BL CL/P anomalies.

Determination of the pharmacodynamic interaction of propofol and dexmedetomidine during esophagogastroduodenoscopy in children.
Propofol is a sedative-hypnotic drug commonly used to anesthetize children undergoing esophagogastroduodenoscopy (EGD). Dexmedetomidine is a highly selective alpha-2 adrenergic receptor agonist that has been utilized in combination with propofol to provide anesthesia. There is currently no information regarding the effect of intravenous dexmedetomidine on the propofol plasma concentration-response relationship during EGD in children. This study aimed to investigate the pharmacodynamic interaction of propofol and dexmedetomidine when used in combination for children undergoing EGD. ⋯ The EC50 of propofol required to produce adequate anesthesia for EGD in children was unaffected by a concomitant infusion of dexmedetomidine 1 microg x kg(-1) given over 10 min.

Depth of sedation using Cerebral State Index in infants undergoing spinal anesthesia.
Infants are noted to frequently sleep during spinal anesthesia, with a concomitant fall in Bispectral Index. However, there are suggestions that EEG derived anesthesia depth monitors have inferior performance in infants. The aim of this study was to quantify the degree of sedation during spinal anesthesia in infants using another EEG derived measure of anesthesia effect--the Cerebral State Index (CSI). ⋯ The degree of burst suppression detected by the CSI in our study supports the hypothesis that infants may have discontinuous patterns of EEG during spinal anesthesia similar to those seen during emergence from general anesthesia. Moreover, the limitations in the application of the adult algorithms to infant EEG may lead to an overestimation of the degree of sedation.
