Question
Answer
Propofol   Rapid onset, short duration hypnosis/no analgesia/ minimal nausea and vomiting/ may cause hypotension  
🗑
Etomidate   nonbarbituate anesthetic/no analgesic effect/side effects include myoclonus, suppression of adrenal function and postoperative nausea and vomiting  
🗑
Opiods   Fentanyl, alfentanil,sufentanil  
🗑
opiods   reduce pain/ used for general anesthesia when circulatory stability is important  
🗑
Benzodiazepines, intermediate acting barbituates   diazepam, lorazepam, midazolam, pentobarbital  
🗑
thiopental   used to induce or supplement sedtion hypnosis/rapid onset, shortduration/respiratory depression  
🗑
Potential adverse effects of inhalation anesthetics   incresed risk of spontaneous abortion/ increased cerebral bloodflow/ malignant hyperthermia  
🗑
desflurane   often used for ambulatory surgery, decrease peripheral vascular resistance  
🗑
isoflurane   rapid induction and emergence/ good analgesic and sedative/pungent, irritating/ cardiovascular system depressant  
🗑
Enflurane   rapid induction and recovery/ good analgesic, muscle relaxant, hypnosis/ pungent/cardiovascular depressant  
🗑
Halothane   fair analgesic and skeletal muscle relaxant, excellent hypnotic/ rapid induction/ cardiovascular depression, unpredictable epatotoxicity/ sensitizes heart to catecholamines, producing extrasystole and arrythmias  
🗑
Nitrous oxide   good anestheticand analgesic no muscle relaxant properties  
🗑
oil case partition coefficient   measures solubility of anesthetic in tissue/ higher coefficient the more potent  
🗑
minimum alveolar concentration   concentration that result sin immobility in 50% of patients when exposed to noxious stimuli
