  • Compile a table, listing the major effects on every system (cardiovascular, CNS, renal, hepatic and uterus) for all the inhalation anesthetics. 
Inhalation drug Cardiovascular CNS Renal Hepatic Uterus
Halothane
  • Decrease BP
  • Sensitized myocardium for arythmogenic effects of catecholamines
  • Fast smooth induction
  • Stadium II absent
  • Increase cerebral blood flow
  • Increase intracranial pressure
  • Decrease glomerular filtration rate
  • Hepatoxicity
  • Decrease muscle contractions
  • Results in external twisting of baby
Enflurane
  • No sensitization of the myocardium
  • Less decrease than halothane
  • Fast smooth induction
  • Convulsions sometimes
  • Decrease glomerular filtration rate
  • Concentration dependent  decrease in portal blood flow
  • Uterine muscle relaxation
Isoflurane
  • No sensitization of the myocardium
  • Less decrease than halothane and enflurane
  • Faster induction and recovery than halothane 
  • Decrease glomerular filtration rate
  • Concentration dependent  decrease in portal blood flow
  • Uterine muscle relaxation
Desflurane
  • Less decrease than halothane and enflurane
  • even faster induction and recover than isoflurane
  • Increase cerebral blood flow and intracranial pressure
  • Decrease glomerular filtration rate
  • Concentration dependent  decrease in portal blood flow
  • Uterine muscle relaxation
Sevoflurane
  • same as desflurane
  • same as desflurane
  • Decrease glomerular filtration rate
  • Concentration dependent  decrease in portal blood flow
  • Undergoes metabolism and is chemically unstable
  • Uterine muscle relaxation
N2O  
  • Weak anaesthetic
  • Potent analgesic
  • Amnesia
  • Decrease glomerular filtration rate
 

 

Name the major acute toxic effects of the inhalation drugs

  • Nephrotoxicity
  • Hematotoxicity
  • Malignant hyperthermia
  • Hepatotocixity
