To begin general anesthesia, medication is given either intravenously (IV) or by having your child breathe anesthetic gas through a mask. The airway is often kept open with a breathing tube. The anesthetic includes inhaled and intravenous medications including pain medication and medication to prevent nausea and vomiting.
Anesthesia professionals will monitor your child closely during surgery. Routine monitors will check on the heart's electrical activity, blood pressure, oxygen levels in the blood and breathing (measuring inhaled oxygen and exhaled carbon dioxide concentrations). In addition, the anesthesiologist may use arterial and central lines to monitor continuous blood pressure and central venous pressure. An arterial line is like a regular IV, but is placed in an artery rather than a vein. Similarly, a central line may be used to monitor central venous pressure.
To manage pain, the anesthesiologist may place an epidural catheter. This thin tubing, placed in the epidural space along the spinal column, allows the physician to give pain medication continually. Pain also may be controlled by giving opioid medications such as morphine or fentanyl through the IV. Transfusion of blood and blood products may be required to replace blood lost during surgery.
