| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
| The evaluation of recovery times between desflurane and sevoflurane general anesthesia in patients ≥ 65 years of age undergoing minor- to moderate-risk noncardiac surgery |
|
| E.1.1.1 | Medical condition in easily understood language |
| Evaluation of wake-up time after desflurane or sevoflurane. |
|
| E.1.1.2 | Therapeutic area | Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Anesthesia and Analgesia [E03] |
| MedDRA Classification |
| 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 |
| Our primary outcome will be the time (in minutes) from discontinuation of volatile anesthetic at the end of surgery until a modified Aldrete score of ≥ 12 points will be reached. We will start to assess postoperative recovery using the modified Aldrete score after arrival at the postoperative care unit (PACU) and thereafter in five minutes intervals. The score consists of 7 modalities (Activity, Respiration, Circulation, Consciousness, Oxygenation, Pain and Emetic Symptoms) with a score of 0-2 points in each criterion. |
|
| E.2.2 | Secondary objectives of the trial |
Secondary Aim 1: The number of liters of supplemental oxygen administered in PACU for SpO2 ≥ 93%.
Secondary Aim 2: The difference in postoperative regional cerebral oxygen saturation (rSO2) between both study groups.
Secondary Aim 3: Postoperative bispectral index values for maximum 90 minutes after surgery in both study groups.
Secondary Aim 4: Self-assessed postoperative RHDS scores in both study groups. The evaluation consists of 8 questions with possible scores for each question of 0-10 points. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1.≥ 65 years of age at time of surgery 2.Scheduled for elective minor- to moderate-risk noncardiac surgery with expected time of surgery ≤ 2 hours
|
|
| E.4 | Principal exclusion criteria |
1.Patients undergoing emergency surgery 2.Patients undergoing bariatric surgery 3.History of documented dementia / neurologic disorder 4.Language, vision, or hearing impairments that may compromise cognitive assessments 5.History of malignant hyperthermia 6.History of structural muscle diseases
|
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| Time between discontinuation of desflurane/sevoflurane at the end of surgery until full postoperative recovery, which is defined as reaching ≥ 12 out of 14 points in the modlified Aldrete score. |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| Upon arrival at the postoperative care unit in 5-minute intervals for a maximum of 90 minutes. |
|
| E.5.2 | Secondary end point(s) |
Secondary Endpoint 1: The number of liters of supplemental oxygen administered in PACU for SpO2 ≥ 93% between both study groups.
Secondary Endpoint 2: Postoperative regional cerebral oxygen saturation (rSO2) between both study groups.
Secondary Endpoint 3: Postoperative bispectral index values for maximum 90 minutes after surgery between both study groups.
Secondary Endpoint 4: Self-assessed postoperative RHDS scores between both study groups. |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
Secondary Endpoint 1: during PACU stay for maximum 90 minutes
Secondary Endpoint 2: during PACU stay for maximum 90 minutes
Secondary Endpoint 3: during PACU stay for maximum 90 minutes
Secondary Endpoint 4: on the evening of the day of surgery (18:00 – 22:00) and in the morning (05:00 – 11:00) and evening (18:00 – 22:00) for the following three days. |
