2. Definition
• Anesthesiology is the field of medicine
focusing on interventions that bring
about a state of anesthesia
• Is characterized by a reversible
1. loss of consciousness,
2. analgesia, amnesia,
3. muscle relaxation.
3. State of anesthesia
• Induced via the administration of
gaseous or injectable agents before
surgical procedures or other medical
interventions
4. Effects:
loss of
awareness
and/or memory
of pain
/experience
Amnesia
temporary
unconsciousness
or the absence
of anxiety.
Hypnosis
adequate muscle
relaxation
Paralysis
relief from pain
or the
prevention of
pain
Analgesia
5. What do anesthesiologist do?
The anesthesiologist provides pain relief before, during and after surgery.
They also fulfill a number of other important roles.
7. The functions they need to monitor include:
heart rate and rhythm
breathing
blood pressure
body temperature
fluid balance
8. Preoperative Evaluation
• Risk stratification is an important part of preoperative planning.
• Low-risk individuals can be evaluated immediately before anesthesia on
the day of the procedure.
9.
10. Postoperative Care
• Monitoring and control of hypothermia and hyperthermia
• Pain control
• Reassurance, reorientation, and potential drug reversal for delayed
emergence (failure to return to a conscious state within 60 minutes of
anesthesia cessation)
• Recovery assessment
12. Critical and emergency care and other roles
• They assess patients, make diagnoses, provide support for breathing and circulation
• help to ensure that infection is prevented.
• providing airway and cardiac resuscitation and support and advanced life support, as
well as pain control
13. Specializations
• cardiac anesthesia, for heart surgery
• pediatric anesthesia, for pain management
and anesthetics in children
• neurasthenia, related to surgery for the
nervous system, brain, and spinal cord
• obstetrics, offering pain relief during labor
and delivery
