General Anesthesia With ETT vs LMA in Patients Undergoing Ablation for Atrial Fibrillation
General Anesthesia With Endotracheal Tube Versus Laryngeal Mask Airway in Patients Undergoing Catheter Ablation for Atrial Fibrillation, a Non-inferiority Trial
In recent years it has been shown that catheter ablation of symptomatic atrial fibrillation (PAF) is superior to antiarrhythmic drug therapy with regards to effectiveness and clinical outcomes. Atrial fibrillation is the most common cardiac arrhythmia, with high rates of concomitant heart failure, stroke and mortality. During an ablation procedure, a patient can be managed with intravenous sedation or General Anesthesia (GA). Within this setting, General anesthesia is associated with improved procedure time and cure rate compared to sedation.
Airway management during GA can be achieved through a laryngeal mask airway (LMA) or an endotracheal tube (ETT). The use of LMA compared to ETT has been shown in different surgical populations to decrease procedure and recovery time, improve hemodynamic stability and reduce anesthetic requirements. It has also shown to decrease airway complications, and postoperative nausea/vomiting which are important factors that affect overall patient satisfaction.
Although general anesthesia in electrophysiology procedures is associated with a higher cure rate, there have been reports of increased airway trauma.Additionally, it is believed that volatile anesthetics may be associated with increased ventricular action potential duration as well as prolonged QT interval. The increased usage of opioids during general anesthesia is also thought to interfere with electrophysiology studies by affecting vagal tone.
At Virginia Commonwealth University (VCU) Health system, Anesthesiologists have been successfully using LMA (General Anesthesia) for ablation in PAF in eligible patients for over five years. The investigators plan to perform a retrospective review of all patients who underwent catheter ablation of PAF at Virginia Commonwealth University Health System from January 2014 - December 2015. The primary endpoint evaluated will be procedure time. Other data collected will include demographics, cardiac history, type of anesthesia, amount of intra-procedure opioids, time to discharge from post anesthesia care unit (PACU), total length of hospital stay, intra-procedure hemodynamics, intra-procedure ionotrope/chronotrope/pressor requirements. and atrial fibrillation recurrence at a 3 month follow-up.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: General Anesthesia with endotracheal tube
Patients assigned to the ETT tube group will have ETT placed in the safest manner deemed appropriate by attending anesthesiologist.
Possible ways to have ETT placed will be using direct laryngoscopy, glidescope or fiberoptic intubations.
Size of ETT will be decided based on patient characteristics and discretion of attending anesthesiologist.
Once placed, auscultation and capnography will be used to ensure correct placement of ETT.
|
Patient randomized to this arm will have general anesthesia with endotracheal tube placed and will be kept at an appropriate depth of anesthesia for patient comfort and procedure needs.
|
ACTIVE_COMPARATOR: General Anesthesia with laryngeal mask airway
Patients assigned to the LMA group will have LMA placed in a standard fashion by anesthesia provider.
LMA size will be decided based on patient characteristics and at the discretion of attending anesthesiologist.
LMA used will be LMA Supreme (Teleflex Medicals, Ireland).
Once placed auscultation will be used to ensure correct placement of LMA.
|
Patients randomized to this arm will have general anesthesia with laryngeal mask airway placed and will be kept at an appropriate depth of anesthesia for patient comfort and procedure needs.
