Study Objective: Emergence delirium is a common complication in preschool children after general anesthesia and may result in undesirable complications. This study aimed to determine whether breathing training after watching an informative video during the pre-operative visit could reduce the incidence of emergence delirium in preschool children after otorhinolaryngologic surgery under general anesthesia.
Design: A single-center, double-blinded, randomized controlled trial.
Setting: Perioperative care.
Patients: A total of 170 children undergoing otorhinolaryngologic surgery, aged 3-7 years, ASA physical status I or II were involved.
Interventions: Patients were randomized to receive breathing training during the pre-operative visit (Training group) or to receive pre-operative visit only (Control group) the day before surgery.
Measurements: Emergence delirium was measured by the Pediatric Anesthesia Emergence Delirium score during the anesthesia recovery time. Data regarding extubation time and post-anesthesia care unit stay time were collected.
Main Results: Children who received breathing training during the pre-operative visit had a significantly lower incidence of emergence delirium than those who only underwent the pre-operative visit (10.4% vs. 35.1%, P < 0.001). The awakening time score and the maximum score in the post-anesthesia care unit were significantly lower in the training group compared with the control group [4.4 ± 3.4 vs. 6.9 ± 4.2, P < 0.001 and 5.0 (5.0) vs 7.0 (7.0), P = 0.001, respectively]. We found no differences in the extubation time and post-anesthesia care unit stay time between groups.
Conclusions: We concluded that breathing training based on video learning during the pre-operative visit in preschool children undergoing otorhinolaryngologic surgery could significantly decrease the incidence of emergence delirium.

Background/objectives: Emergence delirium (ED) is one of the most frequent postoperative complications in pediatric patients after general anesthesia. In adults, a deeper intraoperative level of anesthesia has been reported as an independent predictor of postoperative delirium. However, the effect of anesthetic depth on ED has rarely been demonstrated in the pediatric population.

Background: Remimazolam, an ultra-short-acting benzodiazepine, has similar clinical effects to propofol for sedation in general anaesthesia. However, it remains uncertain whether remimazolam could increase postoperative delirium (POD) compared with propofol.
Objectives: The purpose of our study was to compare the incidence of POD between remimazolam and propofol as sedative agents in general anaesthesia.

Postoperative delirium (POD) is a prevalent complication following cardiac surgery, characterized by acute brain dysfunction observed in critically ill patients. Despite the significant impact of POD, there is currently no established treatment. Recent research has suggested that modulation of cholinergic neurotransmission and α2-adrenergic receptors may offer a therapeutic strategy for managing delirium during critical illness.

Background: Emergence agitation (EA) occurs in preschool children after ophthalmic surgery as eye shields induce visual disturbance. We aimed to investigate the efficacy of light-transmitting eye shields as an alternative to traditional medical gauze eye shields for wound dressing in terms of EA incidence following strabismus surgery.
Methods: We randomly assigned 70 preschool children undergoing bilateral strabismus surgery to receive either light-transmitting (LT group, n = 35) or medical gauze (MG group, n = 35) eye shields upon the completion of surgery.

Postoperative delirium has the potential to impact individuals of all age groups, with a significant emphasis on the elderly population. Its presence leads to an increase in surgical morbidity and mortality rates, as well as a notable prolongation of hospital stays. However, there is a lack of research regarding the prevalence, risk factors, and implications of postoperative delirium in developing nations like Ethiopia, which affects both patients and healthcare institutions.
