Procedural anesthesia: licensed professionals sedate you and monitor you

The doctors at Digestive Care Physicians have contracted with Oracle Anesthesiology to provide the best possible care to patients undergoing surgery or minor procedures such as a colonoscopy. Patients will be given preparation instructions in advance that must be followed exactly to ensure the safe use of procedural anesthesia. While Dr. Ranvir SinghDr. Stephen RashbaumDr. Nitin J. Parikh, or Dr. Long B. Nguyen, is performing the surgical procedure, a Certified Registered Nurse Anesthetist (CRNA), will monitor your vitals and more.

Anesthesiology is a field of medicine practiced by specially trained doctors. It is defined by the American Society of Anesthesiologists as “The practice of medicine dedicated to the relief of pain and total care of the surgical patient before, during and after surgery.”

  • Provides pain relief and maintenance during and immediately following an operation or diagnostic procedure.
  • Monitors vital life functions including heart rate and rhythm, breathing, blood pressure, body temperature, and fluid balance.
  • Assesses the risk of the patient undergoing surgery and optimizes the patient’s condition prior to, during and after surgery.
  • After the procedure, the anesthesiologist maintains responsibility for the patient’s overall care and is required to carry out post-anesthetic evaluation and treatment, directing non-anesthesiology staff as appropriate to maintain a comfortable state for the patient in recovery.

How Does Anesthesia Work?

Anesthetic agents have long been used to ensure more and more patients survive the trauma of surgery. A CRNA combines regional, inhalation, and intravenous agents to attain the right balance for surgery. These three agents service to block pain signals, so patients can be numb to the pain effects. Anesthesia consists of several components, including sedation, unconsciousness, immobility, analgesia (lack of pain) and amnesia (lack of memory). Scientists have developed drugs called anesthetics that target each of these elements. Most anesthetics fall into one of two broad categories: general or local/regional.
