Meta Analysis
Effects of dexamethasone on opioid consumption in pediatric tonsillectomy: a systematic review with meta-analysis.
Tonsillectomy is one of the most common ambulatory procedures performed in children worldwide, with around 40,000 procedures performed in Canada every year. Although a prior systematic review indicated a clear role for dexamethasone as an analgesic adjunct, the quantity effect on opioid consumption is unknown. In the current systematic review with meta-analysis, we hypothesized that the use of dexamethasone reduces perioperative opioid consumption in pediatric tonsillectomy but does not increase rates of postoperative hemorrhage. ⋯ PROSPERO ( CRD42023440949 ); first submitted 4 September 2023.

General anaesthesia (GA) as a pharmacological behaviour management strategy may be indicated for dental extractions in children unable to cooperate in the dental chair. Pain is the most common postoperative complication in children following dental GA. There is conflicting evidence available on the efficacy of local anaesthetic (LA) agents for postoperative pain management following dental extraction. ⋯ Methods of pain assessment varied greatly across included studies, with 14 different pain scales used across the 15 studies. Included studies suggest preoperative oral paracetamol and oral ibuprofen as well as postoperative topical bupivacaine lowered pain scores. This review underscores the challenges in reliably assessing pain in children and highlights the necessity for age-specific validated pain assessment tools.

Randomized Controlled TrialEffect of Intravenous Paracetamol on Postoperative Recovery in Children Undergoing Hypospadias Repair under General Anaesthesia with Caudal Block: A Randomised Controlled Trial.
To explore the impact of perioperative intravenous (IV) paracetamol, administered with caudal ropivacaine on the quality of postoperative recovery in children undergoing hypospadias repair. ⋯ Intravenous paracetamol, Caudal analgesia, Ropivacaine, Paediatric patients.

Numerous, sometimes conflicting, changes in brain functional connectivity have been associated with the transition from wakefulness to unresponsiveness at induction of general anesthesia. However, relatively few studies have looked at the detailed time evolution of the transition, for different electroencephalogram (EEG) frequency bands, and in the clinical scenario of surgical patients undergoing general anesthesia. ⋯ Propofol-induced loss of consciousness in surgical patients is associated with a global breakdown in low-frequency directed functional connectivity, coupled with a high-frequency increase between closely located brain regions. At loss of consciousness, Granger causality shows more pronounced changes than coherence.

Case Reports
Electroencephalogram-Guided General Anesthesia in a Pediatric Patient With Alexander's Disease: A Case Report.
In this case, the electroencephalogram (EEG) was used to guide anesthesia care for a pediatric patient with Alexander's Disease undergoing serial intrathecal injections. Previous procedures using a standard maintenance propofol dose of up to 225 µg/kg/min led to postanesthetic recovery times of over 6 hours, requiring a neurology consult for noncoherence. The EEG assisted in guiding maintenance propofol dosing to 75 µg/kg/min, decreasing postanesthetic wash-off and postanesthesia care unit (PACU) recovery time by 50%. This highlights the potential impact of astrocyte dysfunction on anesthetic sensitivity and robustness of EEG as a biomarker of anesthetic effect, including for pediatric patients with rare neurodevelopmental diseases.
