Surgical Nursing and Anesthesia
Preoperative Preparation
Surgical nursing begins before induction. The technician assesses the patient, confirms fasting status, verifies consent, checks preanesthetic bloodwork, and prepares the surgical site. Aseptic technique-sterile gowns, gloves, drapes, and instrument handling-is foundational. Understand the classifications of wound healing and the difference between clean, clean-contaminated, contaminated, and dirty procedures.
Anesthesia and Monitoring
Know the stages and planes of anesthesia, induction and maintenance agents, and the purpose of premedication. Monitor heart rate, respiratory rate, mucous membrane color, capillary refill time, blood pressure, temperature, and depth of anesthesia. Recognize signs of inadequate anesthesia (increased jaw tone, voluntary movement) and of excessive depth (pale gums, bradycardia, hypotension).
Anesthetic Equipment and Emergencies
Understand the anesthesia machine, vaporizer, breathing circuits, scavenging, and endotracheal tube selection. Know how to respond to apnea, regurgitation, malignant hyperthermia, and cardiac arrest. Recovery care-thermoregulation, airway protection, and pain assessment-is equally testable.
Traps to Watch
Questions may confuse premedication with induction agents or ask about monitoring parameters that change in a specific direction. Read carefully which phase of anesthesia is described.
Worked Example
A patient under anesthesia shows increased jaw tone and rising heart rate. The correct interpretation is a light plane of anesthesia requiring deeper anesthetic delivery or additional analgesic-not a sign of adequate depth.
Rule of Thumb
If the patient can respond to surgical stimulation, anesthesia is too light; if reflexes and perfusion are lost, it is too deep.
