On the first day after the surgery, in the comprehensive surgical ward, Yang Ping was leading everyone on their ward rounds.
Teacher Sun was wrapped in bandages from head to toe, except for his eyes and mouth. Of course, his excretory outlets weren't covered either.
The bandages didn't need to be changed for a full 12 days, after which they could finally be removed. For these 12 days, Teacher Sun could only urinate via a catheter, defecate bedridden aided by a bedpan, and meals were manually fed. If necessary, a gastric tube might be used to grind and liquify the food, which would then be directly pumped into his stomach. All eating, drinking, urinating, and defecating occurred while he was in bed. This was what they called "absolute bed rest".
Absolute bed rest required lying in bed every single moment. Even a brief period of leaving the bed would break the rule of absolute bed rest.
