general anesthetics
| 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 |
| commonly used inhaled anesthetics | nitrous oxide, halothane, enflurane, isoflurane,sevoflurane |
| stage I | analgesia, amnesia |
| stage II | loss of conciousness |
| stage III | surgical anesthesia Loss of eyelash reflex |
| plane I | pupils constricted, intercostal muscles for ventilation |
| pane II | mid dilated pupils, mixed ventilation |
| palne III | absence of corneal reflex, diaphragmatic ventilation |
| plane IV | max. pupilary dilation, apnea circulatory depression |
| stageIV | medulary paralysis |
