THE jOURNAL OF EXTRA-CORPOREAL TECHNOLOGY Technique Simplified Solution to Eliminating Electrical Noise During Cardiac Surgery
نویسنده
چکیده
Electrical noise will be present in the operating room even under ideal circumstances. The addition of the cardiopulmonary bypass machine to the other machinery in the operating room introduces one more source of electrical noise. Identifying and managing this interference may aid in reducing artifactual signals on the electrocardiogram (EKG) monitor. If electrical interference occurs during the onset of cardiopulmonary bypass, an uninterpretable rhythm pattern on the electrocardiogram monitor may be present. Adding an extra ground from the main pump head to the heater/cooler helps to reduce noise and, therefore, effectively diminishes pump-generated artifact on the EKG.

Custodiol HTK cardioplegia use in robotic mitral valve.
Robotic surgery is a growing subspecialty in cardiac surgery. Custodiol HTK cardioplegia offers long-term myocardial protection, decreased metabolism, and eliminates multiple cardioplegia dosing. This article reviews the technique, strategy, and considerations for use of Custodiol HTK for myocardial protection in robotic mitral valve surgery.
متن کاملUse of the Quest Myocardial Protection System (MPS) for modified ultrafiltration during pediatric cardiac surgery.
Modified ultrafiltration generally is considered a standard of care for treating children undergoing cardiopulmonary bypass for congenital heat surgery. Different methods, incorporating a variety of devices and technologies, have been described. The present report describes a technique of modified ultrafiltration using arterial-venous flow with the Quest Myocardial Protection System (MPS).
متن کاملEmergent Cardiopulmonary Bypass during Cardiac Surgery.
During orientation to the cardiac surgery operating room, new staff may not be exposed to emergent situations. Allowing team members the opportunity to practice their roles during less common, high-stakes emergency cardiac surgical scenarios may better prepare them when crises do arise in the OR. The Emergency Cardiopulmonary Bypass Course was developed to meet the needs of new staff starting i...
متن کاملGeneral anesthesia in cardiac surgery: a review of drugs and practices.
General anesthesia is defined as complete anesthesia affecting the entire body with loss of consciousness, analgesia, amnesia, and muscle relaxation. There is a wide spectrum of agents able to partially or completely induce general anesthesia. Presently, there is not a single universally accepted technique for anesthetic management during cardiac surgery. Instead, the drugs and combinations of ...
متن کاملUse of del Nido cardioplegia solution and a low-prime recirculating cardioplegia circuit in pediatrics.
The evolution of myocardial protection techniques has been both the source of milestone advancements and controversial debate in cardiac surgery. Our institution has modified a low-prime cardioplegia system (CPS) and adopted a single-dose cardioplegia solution (del Nido cardioplegia) for our congenital heart disease population. The goal of this article is to describe our CPS and outline our myo...
