E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Healthy adult surgery patients. Health status ASA1 or ASA2 as categorised by a medical doctor at the hospital based on medical history, physical examination. The American Society of Anesthesiologists physical status (ASA-PS) ASA1 and ASA2 (ASA1 is defined as “Healthy, non-smoking, no or minimal alcohol use” and ASA2 is defined as “Mild diseases only without substantive functional limitations). Being eligible for day surgery means participants are overtly healthy as determined by clinical staff. |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary purpose of the RCT AFFECT is to identify, distinguish and compare the different affective states of the participants after the administration of one of three opioids: morphine, oxycodone and fentanyl, (equivalent to 10mg morphine, i.e. equianalgesic dose), commonly used in surgery settings before the induction of general anesthesia. |
|
E.2.2 | Secondary objectives of the trial |
To determine the relation between subjective affective states as reported by the participants with objective measures: heart rate variability (HRV), breathing and vasodilation/constriction used as proxy of physiological stress response. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Participants are eligible to be included in the study only if all of the following criteria apply:
Age: 1. Participants must be 18 years of age or above at the time of signing the informed consent. Type of Participant and Disease Characteristics: 2. Health status ASA1 or ASA2 as categorised by a medical doctor at the hospital based on medical history, physical examination, laboratory test etc. unrelated to the current study. The American Society of Anesthesiologists physical status (ASA-PS) ASA1 and ASA2 (ASA1 is defined as “Healthy, non-smoking, no or minimal alcohol use” and ASA2 is defined as “Mild diseases only without substantive functional limitations). Being eligible for day surgery means participants are overtly healthy as determined by clinical staff.
Weight: 3. Body weight and body mass index (BMI) within the range 18-35 kg/m2 (inclusive).
Informed Consent: 4. Capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
Other criteria: 5. Having good verbal communication skills in Norwegian, 6. Patients undergoing planned day surgery with general anesthesia (outpatient sample), a. Orthopedic, rectal, gynecological, hand and foot surgery, and minor vascular procedures, 7. Inpatients undergoing planned gynecological and orthopedic surgery, a. Hysterectomia, laparascopic ovarectomia, lumbal herniotomy and other related procedures.

E.4 | Principal exclusion criteria |
Medical Conditions 1. Known allergic reactions to any opioid, 2. Severe chronic obstructive lung disease, 3. Cor pulmonale, 4. Severe bronchial asthma, 5. Severe respiratory failure with hypoxemia and hypercapnia, 6. Moderate to severe hepatic impairment, 7. Moderate to severe kidney failure, 8. Acute abdomen, 9. Increased brain pressure, 10.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoints will be the mean differences between different affective states reported by the participants on the operating table using a verbal numeric rating scale (NRS 0-10). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The study starts the day of the surgery, and all the relevant measures will be taken before/after the opioid administration. The end of the study is defined as the end of the anesthesia induction on the same day. A participant is considered to have completed the study if he/she has completed all phases of the study, including the interview at T3 just before falling asleep.
• Numeric rating scales (0-10) on affective states before (T3a) and after opioid administration (T3c). • Numeric rating scales (0-10) on acute drug effects after opioid administration selected from the Drug Effects Questionnaire (DEQ) (T3c) |
|
E.5.2 | Secondary end point(s) |
• Correlations between subjective and objective measures. • Mean differences on the objective measures before and after opioid administration: • (HRV) • Breathing rate • Vasodilation/constriction
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
• ECG, respiratory rate, and blood pressure before and after opioid administration • Vasodilation/ constriction and after opioid administration |
