Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The surgeons were tested in a laparoscopic simulator at 8 a.m. day 1, 4 a.m. day 2, and again at 8 a.m. day 4. At the same given times they would perform the d2 test of attention and prescribe medicine in the Electronic Patient Medication system in accordance with a case they were given. Furthermore they delivered a salivary sample for the determination of salivary cortisol, at the given times.
They sampled urine from 9 pm - 9 am all 4 days, in order to measure the production of melatonin in urine.
The surgeons would fill out the Karolinska sleepiness scale, VAS (Visual Analog Scale) fatigue, VAS sleep quality and VAS general well being at 8 a.m. day 1, 4 a.m. day 2, and again at 8 a.m. day 4. The Karolinska Sleepiness scale was filled out every second hour on day 2 from 4pm - 8 am on day 3.
