Using the Perfusion Index to predict changes in the depth of anesthesia in children compared with the A-line Autoregression Index: an observational study.

Background: We investigated the performance of the Perfusion Index (PI) derived from pulse oximetry waveform as a tool for assessment of anesthetic depth in comparison with A-line Autoregression Index (AAI) derived from analysis of Middle-Latency Auditory Evoked Potentials (MLAEP) waveform integrated by aepEXplus monitor in children receiving sevoflurane anesthesia for tonsillectomy.

Methods: Forty-one patients (4..

[Oral trans-mucosal dexmedetomidine for controlling of emergence agitation in children undergoing tonsillectomy: a randomized controlled trial].

Objectives: Emergence agitation is a negative behavior commonly recorded after pediatric tonsillectomy. We investigated the efficacy of preoperative premedication with oral transmucosal buccal dexmedetomidine on the incidence and severity of emergence agitation in preschool children undergoing tonsillectomy under sevoflurane anesthesia.

Methods: Ninety patients aged (3–6 years), ASA I‒II were enrolled into three groups (n = 30) to receive oral transmucosal dexmedetomidine 0.

[Preemptive nebulized ketamine for pain control after tonsillectomy in children: randomized controlled trial].

Objectives: The administration of ketamine as nebulized inhalation is relatively new and studies on nebulized ketamine are scarce. We aimed to investigate the analgesic efficacy of nebulized ketamine (1 and 2 mg.kg) administered 30 min before general anesthesia in children undergoing elective tonsillectomy in comparison with intravenous ketamine (0.
