What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Modified Observers Assessment of Alertness/Sedation (MOAA/S) Score 2 Minutes From Beginning of Maintenance Period
Time Frame: 2 minutes from the beginning of the maintenance period
The MOAA/S is a 6-point ordinal scale measuring a patient's level of sedation. Scores range from 0 (No response to painful stimulus [trapezius squeeze]) to 5 (Responds readily to name spoken in normal tone [awake]). MOAA/S scores were classified as 0-1, 2-4 and 5.
2 minutes from the beginning of the maintenance period
Modified Observers Assessment of Alertness/Sedation (MOAA/S) Score 4 Minutes From Beginning of Maintenance Period
Time Frame: 4 minutes from the beginning of the maintenance period
The MOAA/S is a 6-point ordinal scale measuring a patient's level of sedation. Scores range from 0 (No response to painful stimulus [trapezius squeeze]) to 5 (Responds readily to name spoken in normal tone [awake]). MOAA/S scores were classified as 0-1, 2-4 and 5.
4 minutes from the beginning of the maintenance period

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Satisfaction With Sedation Instrument (PSSI) Questionnaire
Time Frame: 24 - 48 hours after completion of the procedure
The PSSI is a 100-point visual analog scale measuring a patient's satisfaction with sedation. Scores range from 0 (Very dissatisfied) to 100 (Very satisfied).
24 - 48 hours after completion of the procedure
Blood Concentrations of Propofol
Time Frame: At the end of the initiation period and every 2 minutes during the maintenance period
Blood concentration of ICI35,868 (propofol)
At the end of the initiation period and every 2 minutes during the maintenance period
Modified Observers Assessment of Alertness/Sedation (MOAA/S) at End of Initiation Period
Time Frame: Last measurement in maintenance period (3 minutes for arms 1-5; 1 minute for arm 6, 5 minute for arm 7)
The MOAA/S is a 6-point ordinal scale measuring a patient's level of sedation. Scores range from 0 (No response to painful stimulus [trapezius squeeze]) to 5 (Responds readily to name spoken in normal tone [awake]). MOAA/S scores were classified as 0-1, 2-4 and 5.
Last measurement in maintenance period (3 minutes for arms 1-5; 1 minute for arm 6, 5 minute for arm 7)
