Summary

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.

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.

• Local Infiltration
• Atrial Septal Defect

Interventions

Type	Name	Description
OTHER	General Anesthesia	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.
OTHER	Local anesthesia	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
