Monitoring the Depth of Anesthesia and Nociception During the Induction of General Anesthesia in Pediatric Patients

Plain-language summary

Perioperative assessment of adequate depth of anesthesia and analgesia is currently a recommended part of routine anesthesia practice for all surgical procedures. In most cases, it is performed by monitoring and evaluating physiological parameters, which is insufficient, especially for the depth of anesthesia. The depth of anesthesia, when measured with the Conox device, is indicated by the qCON index, the recommended value for anesthesia management is between 40-60. Shallow (above 60) anesthesia may be associated with an increased incidence of perioperative wakefulness episodes, and deeper (below 40) anesthesia may lead to a more frequent occurrence of adverse effects of anesthesia, including emergent delirium in the postoperative period. In addition to assessing the depth of anesthesia, the Conox device also allows for instrumental assessment of analgesia. Inadequate analgesia increases postoperative discomfort and may contribute to an increased incidence of complications in anesthesia and during the postoperative period. Instrumental monitoring of the depth of anesthesia and analgesia increases the safety of anesthesia care. During perioperative care, periods with significant painful stimulation include not only the surgical procedure itself but also airway management during induction of general anesthesia, especially intubation. The hypothesis is - due to the significant painful stimulation during airway management during induction of anesthesia, adequate depth of anesthesia and analgesia may be insufficient and is associated with the patient's clinical response, which may be associated with the occurrence of postoperative delirium.
