Brief summary
The purpose of this research study is to compare the safety and effectiveness of three commonly used techniques for delivering anesthesia during a procedure known as esophagogastroduodenoscopy.
Detailed description
Different anesthetic techniques are currently in use at Cincinnati Children's Hospital Medical Center (CCHMC) for delivering anesthesia during an esophagogastroduodenoscopy (EGD). Because there is a lack of evidence to delineate the best techniques, pediatric anesthesiologists select the technique based on clinical preference and experience. One anesthetic technique involves the use of general anesthesia with the placement of an endotracheal tube, and maintenance with an inhalation agent, such as sevoflurane (IS). These patients may be extubated under deep anesthesia in the operating room, and allowed to awaken in the post anesthesia care unit. A similar technique involves the placement of an endotracheal tube, and anesthetic maintenance with a continuous infusion of propofol (IP). These patients are also extubated under deep anesthesia in the operating room, and allowed to awaken in the postoperative care unit. The third technique does not use an endotracheal tube and anesthetic maintenance occurs with continuous infusion of propofol with the patient breathing oxygen through their natural airway (NA). Our objective in this study is to compare outcomes between these three established anesthetic techniques. Children in the study will be recruited from Cincinnati Children's Hospital Medical Center Operating Room Schedule. They will be cared for in the Operating Rooms and Post Anesthesia Care Unit.
Interventions
Anesthesia will be maintained with sevoflurane 3% in oxygen at 2 L/min. The endoscopist will begin the procedure. The sevoflurane inspired concentration will be adjusted between 1 to 2 times the minimum alveolar concentration (MAC) by the attending anesthesiologist to maintain an appropriate level of anesthesia.
Anesthetic maintenance will be with 2 L/min flow of oxygen through the endotracheal tube and a continuous propofol infusion at a rate of 250 mcg/kg/min. A maximum of two bolus doses of propofol 0.5 to 1 mg/kg and an increase in the continuous infusion to 300 mcg/kg/min may be given at the discretion of the anesthetist if necessary to provide adequate anesthesia.
A nasal cannula will be placed with oxygen administered at a rate of 3 L/min, and a bite block will be inserted. Zofran will be administered. Anesthesia will be maintained with a continuous propofol infusion at a rate of 250 mcg/kg/min. A maximum of two bolus doses of propofol 0.5 to 1 mg/kg, and an increase of the continuous infusion to 300 mcg/kg/min may be given at the discretion of the anesthetist.
