Study Notes

Endotracheal Intubation Procedure

Involves inserting an endotracheal (ET) tube into the trachea for oxygen and inhalation agents during anesthesia.
A laryngoscope is used for exposure and illumination of the throat and larynx.
The ET-tube is positioned roughly 1/2 inch below the vocal cords; nasal intubation may be required in some cases.
Cuff inflation secures the airway, preventing aspiration during surgery.
Difficult intubation can lead to complications like laryngospasm or bronchospasm.
Intubation is not performed until the patient reaches stage III of anesthesia; muscle relaxants are generally administered beforehand.

Assisting the Anesthetist with Intubation

Pass necessary items swiftly, such as laryngotracheal anesthesia syringe and ET-tube.
Apply directed pressure to the cricoid cartilage to assist in visualization of vocal cords and reduce aspiration risk.
Carefully remove the stylet when instructed; ensure ET-tube remains stationary.
Inflate the ET-tube cuff with the correct volume of air as guided by the anesthetist.
Confirm ET-tube placement by monitoring chest rise and breath sounds, using a capnograph to detect CO2 presence.
If the ET-tube enters the esophagus, it must be removed and reinserted.

Crash or Rapid Sequence Induction

Employed for patients with a full stomach to reduce aspiration risks during anesthesia.
Administer oxygen for 3-5 minutes pre-induction; firm cricoid pressure applied during muscle relaxant administration.
Manual ventilation is generally avoided before intubation unless absolutely necessary.
Post-intubation, the anesthetist confirms ET-tube position before releasing cricoid pressure.

Maintaining Anesthesia (Phase II)

Patient remains in stage III (surgical plane) for the duration of surgery.
Positioning is crucial: requires consent from the anesthetist to avoid injury or pressure sores.
Monitor blood and body fluid loss, including measuring blood loss and fluid output.
Retrieve and provide additional anesthesia supplies and assist in blood transfusions if required.
Assist with starting and monitoring invasive lines, like CVP or arterial monitoring.

Emergence from General Anesthesia (Phase III)

Emergence phase details the patient's awakening process as anesthetic agents decrease.
100% oxygen is administered as muscle relaxants may require reversal.
Patients may experience restlessness and should be gently restrained to prevent injuries.
Extubation occurs once patients breathe spontaneously and normal reflexes return.
After extubation, patients are monitored for stability and transported to the postanesthesia care unit.
Suction equipment should remain available for reintubation emergencies.
Provide warmth to the patient post-anesthesia, as they may be sensitive to temperature changes.

Assisting During Emergence

Support the anesthetist by staying nearby and offering reassurance or hands-on assistance as needed.
Prepare for potential reintubation and assist with patient transport preparations post-extubation.
Ensure all medical equipment, including drains and catheters, is secured prior to transport.
Monitor and measure contents of drainage containers for the anesthetist.
