Article Abstract
Paediatric magnetic resonance imaging (MRI) allows visualisation of internal structures in children without the use of ionising radiation. It often requires sedation to minimise patient's movement to enhance image quality. Dexmedetomidine and propofol are widely used as sedative agents, however, their comparative efficacy remains debated. This systematic review and meta-analysis, conducted from May to November 2023, examined 13 randomised controlled trials with 650 paediatric patients. Results favoured dexmedetomidine over propofol for reducing patient movement during MRI (SMD -0.68; 95% CI -1.16, -0.20; p = 0.005). However, sedation efficacy and adverse events showed no significant difference (RR 0.99; 95% CI 0.96, -1.01; p = 0.252 vs. RR 0.95; 95% CI 0.73, -1.23; p = 0.692), respectively. The findings highlight the potential of dexmedetomidine to improve MRI quality by reducing motion. However, further research is needed on diverse patient populations, long-term effects, and aspects such as cost-effectiveness and patient satisfaction to validate these results across broader contexts. Key Words: Paediatric MRI, Dexmedetomidine, Propofol, Sedation, Systematic review, Meta-analysis, Randomised controlled trials.

Different classes of anesthetics can induce unconsciousness despite acting through distinct biological mechanisms. This raises the possibility that they produce a convergent effect on the dynamics or temporal evolution of neural population activity. To explore this, we analyzed intracortical electrophysiological recordings during infusions of propofol, ketamine, and dexmedetomidine, using a rigorous method to estimate dynamical stability.

Upper gastrointestinal endoscopy (GIE) is essential for diagnosing and treating gastrointestinal disorders in children aged 6-12 years, yet it often requires sedation due to the significant discomfort and pain involved. We conducted a PRISMA 2020-compliant systematic review of randomized controlled trials (RCTs) from PubMed, Web of Science, Scopus, and Ovid (inception to March 30, 2024). Inclusion criteria are as follows: RCTs comparing sedative regimens (e.

May-Thurner syndrome (MTS) is characterized by the compression of the left common iliac vein by the overlying right common iliac artery, which can lead to venous insufficiency, obstruction, and an increased risk of iliofemoral deep vein thrombosis (DVT) and pulmonary embolism (PE). We report the perioperative anesthetic management of a 38-year-old female with symptomatic MTS who underwent a total laparoscopic hysterectomy, bilateral salpingectomy, and lysis of adhesions for abnormal uterine bleeding. The patient had a history of persistent left lower extremity symptoms despite prior left common iliac vein stenting and was on chronic anticoagulation therapy with rivaroxaban.

Background: Spinal cord stimulation is a validated approach for managing chronic pain syndromes. The stimulator placement typically requires sedation, and an awake phase is needed to ensure optimal lead positioning. We describe a novel multimodal sedation approach using target-controlled infusions of propofol, remifentanil, and dexmedetomidine, combined with boluses of ketamine, guided by electroencephalography and nociception-antinociception balance monitoring.

This report describes a case of a 15-year-old pediatric patient with mitochondrial depletion syndrome, associated with hypertrophic cardiomyopathy, who underwent scoliosis correction surgery under neurophysiological monitoring. As propofol is mitochondrion-toxic, the anesthetic approach was modified to involve dexmedetomidine infusion combined with boluses of midazolam and ketamine. The patient was hemodynamically stable during surgery with effective neuromonitoring readings, and the surgery was concluded uneventfully.
