Minor outpatient surgeries account for 25% of all elective surgeries. Ambulatory surgical procedures currently account for up to 70% of the total volume of scheduled operations. Still, major surgeries are performed on the concept of a rapid removal, which in some cases occurs only 20 hours after the intervention (orthopedic procedures, etc.).
Postoperative pain, nausea and vomiting are the causes that most commonly delay the discharge of sick patients and require rehospitalization.
