  Purpose
Elderly patients show different pharmacokinetic and pharmacodynamic variables and usually need smaller doses of anaesthetic drugs than younger patients. The purpose of this study was to investigate the optimal effect-site concentration of remifentanil for preventing cough during emergence in elderly patients under sevoflurane and remifentanil anesthesia.

Primary Outcome Measures:
  • Number of cough [ Time Frame: from end of surgery to 5 min after tracheal extubation ]
    Number of cough or a strong and sudden contraction of the abdomen during periextubation periods


Enrollment: 47
Study Start Date: February 2015
Study Completion Date: December 2015
Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Elderly
Remifentanil was maintained at predetermined effect-site concentration during the emergence period in elderly patients.
Drug: Remifentanil
Remifentanil was maintained at predetermined effect-site concentration during the periextubation period (initial concentration: 1.8 ng/ml) in adult patients (20-60 years) .
Other Name: Ultiva
Drug: Sevoflurane
Anesthesia was maintained with sevoflurane with 1.5-2.0 vol% in air/50%oxygen mixture, and sevoflurane was adjusted to about 1.0 vol% 10 min before end of surgery.
Active Comparator: Adult
Remifentanil was maintained at predetermined effect-site concentration during the emergence period in adult patients.
Drug: Remifentanil
Remifentanil was maintained at predetermined effect-site concentration during the periextubation period (initial concentration: 1.8 ng/ml) in elderly patients (65-80 years) .
Other Name: Ultiva
Drug: Sevoflurane
Anesthesia was maintained with sevoflurane with 1.5-2.0 vol% in air/50%oxygen mixture, and sevoflurane was adjusted to about 1.0 vol% 10 min before end of surgery.
