Anaesthetics Flashcards
Major causes of morbidity and mortality in anaesthetics
Aspiration pneumonitis
Pneumonia
Meds which are given before general anaesthetic
Benzodiazepines
Opiates
Alpa 2 agonists(clonidine)
Types of general anaesthesia
Hypnosis
Muscle relaxation
Analgesia
Examples of hypnotic agents and why are they given
Used to make patient unconscious
Propofol
Ketamine
Sevoflurane
NOS
Most commonly used agent for induction and maintenance of a general anaesthetic
Propofol
Types of muscle relaxants
Depolarising (e.g., suxamethonium)
Non-depolarising (e.g., rocuronium and atracurium)
What can be used for reversal of neuromuscular blocking medications
Cholinesterase inhibitors (e.g., neostigmine)
when should cyclizine be used with caution
Heart failure
Elderly patients
Risks of GA
Waking Aspiration Dental injury Anaphylaxis Malignant hyperthermia
Agents associated with malignant hyperthermia
Volatile anaesthetics (isoflurane, sevoflurane and desflurane) Suxamethonium
Presentation of malignant hyperthermia
Increased body temperature (hyperthermia) Increased carbon dioxide exhalation Tachycardia Muscle rigidity Acidosis Hyperkalaemia
Mx of malignant hyperthermia
Dantrolene
Side effects of spinal anaesthesia
hypotension, sensory and motor block, nausea and urinary retention
Preferred option for major open abdominal procedures and post-op resp compromise - anaesthesia
Epidural
Complication and contraindication of epidural
Epidural haematoma
Contraindicated in coagulopathies
