Eksperimentel: remifentanil for intranasal surgery
|
The target Ce of remifentanil was determined by the response of the previous patient using Dixon's up-and-down method.
If the patients did not cough throughout peri-extubation period, the extubation was defined as a smooth emergence, and the predetermined concentration of remifentanil for the subsequent patient was decreased by 0.5 ng ml-1.
Similarly, if the patient cough anytime around extubation it was considered as failed smooth emergence and the predetermined concentration was increased by 0.5 ng ml-1 for the next patient.
The patients were enrolled until getting at least six cross-over pairs in Dixon sequential allocation method.

Tidsramme |
|---|---|---|
|
cough incidence
Tidsramme: from sevoflurane discontinuation (at the end of anesthesia) to 5 min after extubation
|
Cough is defined as a strong and sudden contraction of the abdomen or forced exhalation movement.
|
from sevoflurane discontinuation (at the end of anesthesia) to 5 min after extubation
|
|
cough grade
Tidsramme: from sevoflurane discontinuation (at the end of anesthesia) to 5 min after extubation
|
Cough occurrence and number are recorded according to the grading system as follow; Grade 0 - no cough Grade 1 - light (single) cough Grade 2 - moderate cough (more than 1 episode of non-sustained cough) Grade 3 - sustained and repetitive cough movement and head lift.
