ABSTRACT
BACKGROUND:
This study determined the dose of remifentanil to use during insertion of a Classic(TM) laryngeal mask airway (LMA, The Laryngeal Mask Co., Nicosia, Cyprus) in elderly patients during emergency airway management when combined with a single dose of propofol.METHODS:
Patients aged 65-80 years were enrolled. Anesthesia was induced with propofol 1 mg/kg, and then a blinded dose of remifentanil was infused over 30 s after confirming the patient's loss of consciousness. The dose of remifentanil was determined using Dixon's up-and-down method, starting at 0.5 microg/kg (a step size of 0.1 microg/kg). Insertion of the LMA was attempted 60 s after loss of consciousness.RESULTS:
In total, 23 patients were recruited and the mean age +/- standard deviation was 72 +/- 3 years. The effective dose for successful LMA insertion in 50% of the patients (ED50) was 0.20 +/- 0.05 microg/kg. No patient needed more than 0.3 microg/kg.CONCLUSIONS:
Remifentanil 0.20 +/- 0.05 microg/kg with propofol 1 mg/kg resulted in excellent LMA insertion in 50% of elderly patients without significant hemodynamic changes during emergency airway management.
