About this study
Official title: A Comparative Study Between General Anesthesia Versus Sedation By Dexmedetomidine and Ketamine With Local Infiltration for Percutaneous Transcatheter Closure of Atrial Septal Defect in Pediatric Patients
The aim of the present study is to compare between general anesthesia versus sedation with dexmedetomidine and ketamine with local infilteration at the catheter insertion site in pediatric patients undergoing transcutaneous closure of atrial septal defect on hemodynamic changes.
Read the detailed description
Atrial septal defect (ASD) is one of the most common types of congenital heart defects, occurring in about 25% of children General anaesthesia is usually obtained with tracheal intubation and mechanical ventilation or spontaneous breathing, the depth of anesthesia required to tolerate the presence of a tracheal tube will invariably lead to some reduction in myocardial contractility and alteration of respiratory mechanics. The goal of anesthetic technique is to provide sedation and analgesia during cardiac catheterization to ensure immobility and hemodynamic stability.
Ketamine is an N-methyl-D-aspartate receptor (NMDA) antagonist with sedative, analgesic, and sympathomimetic effects. Among its benefits ,it has the ability to protect airway reflexes with minimal effect on ventilatory drive.
Dexmedetomidine is a highly selective alpha-2 adrenoreceptor agonist with sedative, anxiolytic, and analgesic effect, it also blunts the sympathetic nervous system response to surgical stimulation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
General AnesthesiaOther
General anesthesia will be induced by 6% sevoflurane with a face mask. An intravenous line(22-g cannula )will be inserted then fentanyl 1mcg-kg will be given . Endotracheal tube will be used to intubate the patient .Anesthesia will be maintained by 2%sevoflurane inhalation in an oxygen air compination 1:1 throught the operation . Crystalloid solution was used to replenish fluid according "4/2/1-rule". Monitoring during the procedure include , ejection fraction (EF),blood pressure, heart rate, respiratory rate, and O2 saturation are measured at baseline, after induction, 10 min after catheter insertion,30 min during procedure and post emergence.
Local anesthesiaOther
A nasal cannula was placed and oxygen delivered at 2 to 3 L/minute. An intravenous line will be inserted (22-g cannula). The sedation regimen will include loading dose of dexmedetomidine (1 mcg/kg) and ketamine (1mg/kg) over 10 minutes . The patient will receive an infusion of dexmedetomidine at 0.7 mcg/kg per hour and ketamine 0.5 mg/kg/hr as maintenance sedation .Local infilteration of xylocaine 2% at dose 2mg/kg will be given for vascular access in cardiac catheterization . After completion of the procedure the infusion pump will be stopped to ensure that the patient is fully awake and vitally stable

Questions about this trial
What is this clinical trial studying?
A study testing General Anesthesia and Local anesthesia in people with General Anesthesia and Dexmedetomidine, run by Tanta University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Heart rate (time frame: Immediately after the intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2026.
