Anesthesia Flashcards
Phases of anesthesia
- Induction
- maintenance
- emergence
- recovery
Patient under anesthesia exhibits:
- Analgesia
- amnesia
- loss of reflexes
- skeletal muscle relaxation
What are the ways in which anesthesia can be administered?
- IV
- Inhalation agents
- Or combo of both
Theories r/t mechanism of anesthetic agents
Ps 1 classification
The patient is healthy.
PS2
PS3
PS4
PS5
PS6
Anesthesia is induced with a variety of different methods
General anesthetic agents
Inhalation agents
Most commonly used
Nitrous oxide, isoflurane, desflurane,
Inhalation agents
Barbiturate agents
Nonbarbituate induction agents
Adjunct anesthesia agents
Narcotics
Benzodiazepines
Neuromuscular blockers (muscle relaxants)
Balanced anesthesia
Unconscious state is induced by induction agents, inhalation agents, and muscle relaxants
A narcotic and/or benzodiazepine is injected and ventilation is monitored
Anesthesia process
Anesthesia process part II
Anesthesia process part III
Common induction agents
Inhalational agents
Muscle relaxants
Physiologic indicators of a difficult airway
Intubation with an endotracheal tube
Reactions to intubation
Maintenance phase
Oxygenation during the maintenance phase
Maintenance phase: ventilation
Maintenance phase: circulation
Maintenance phase: body temp
Maintenance phase: carbon dioxide
Four stages of maintenance phase
Four stages of maintenance phase: 1. Relaxation
Four stages of maintenance: 2. Excitement
Four phases of maintenance: 3. Operative or surgical anesthesia
Four phases of maintenance: 4. Danger
BIS (Bispectral index system
Emergence phase
Phase 4: Recovery
Laryngospasm
Sugammadex
Rocuronium
