Study Notes
Establishing Depth of Anesthesia
- Depth of anesthesia can be established through physical examination and monitoring of vital signs.
Risks of Excessive Anesthesia
- Giving too much anesthesia drug can lead to respiratory depression, cardiac arrest, and even death.
Importance of Hindbrain Function
- Maintaining hindbrain function during anesthesia is crucial to ensure the patient's vital functions, such as heart rate and breathing, remain stable.
Monitoring Patients during Anesthesia
- The purpose of monitoring patients during anesthesia is to detect and respond to any abnormalities that may occur.
- Monitoring helps to prevent complications, such as respiratory depression, cardiac arrest, and hypothermia.
Consequences of Unaddressed Abnormalities
- If abnormalities during anesthesia are left unaddressed, they can lead to serious complications, such as cardiac arrest, respiratory failure, and even death.
Anesthesia Monitoring Charts
- Anesthesia monitoring charts are used to record vital signs and other important data during anesthesia.
- The charts are retained post-operatively to provide a record of the patient's anesthesia care.
Heart Rate Monitoring
- Heart rate readings are typically recorded every 5 minutes during anesthesia monitoring.
- Increased heart rate readings during anesthesia monitoring can indicate stress, anxiety, or other complications.
Main Responsibility of Anesthetist
- The main responsibility of the anesthetist during anesthesia is to ensure the patient's safety and well-being.
Palpebral Reflexes
- A common mistake when checking palpebral reflexes is to press too hard on the eyelid, which can cause the patient to respond even if they are anesthetized.
Slow Recoveries and Post-Operative Wound Infections
- One of the top causes of slow recoveries and post-operative wound infections is hypothermia.
Temperature Monitoring
- Temperature can be monitored during anesthesia using an esophageal temperature probe or other devices.
- The esophageal temperature probe should be inserted through the nose or mouth and advanced into the esophagus.
Patient Warming
- Patient warming should be initiated when the patient's temperature drops below 36°C.
- The aim of patient warming is to maintain a normal body temperature and prevent hypothermia.
Aim of Monitoring during Anesthesia
- The aim of monitoring during anesthesia is to detect and respond to any abnormalities that may occur, and to ensure the patient's safety and well-being.
Key Factors in Monitoring during Anesthesia
- Key factors in monitoring during anesthesia include heart rate, blood pressure, oxygen saturation, and temperature.
Consequences of Hypothermia
- Hypothermia during anesthesia can lead to decreased tissue perfusion, cardiac complications, and increased risk of infection.
Decreased Tissue Perfusion
- Decreased tissue perfusion can lead to decreased oxygen and nutrient delivery to the tissues, which can cause tissue damage and organ dysfunction.
Causes of Decreased Tissue Perfusion
- Causes of decreased tissue perfusion include hypovolemia, cardiac complications, and vasopressor use.
Importance of Maintaining Tissue Perfusion
- The aim of maintaining tissue perfusion during anesthesia is to ensure that the tissues receive adequate oxygen and nutrients to prevent tissue damage and organ dysfunction.
Consequences of Not Maintaining Tissue Perfusion
- If tissue perfusion is not maintained during anesthesia, it can lead to tissue damage, organ dysfunction, and even death.
