About

The underlying causative mechanism that leads to intraoperative hypotension (IOH) may vary depending on the stage of anesthesia and surgery, which determines different IOH types. Naturally, the incidence and severity of IOH types will differ, as will the incidence and severity of postoperative complications.

Background The underlying causative mechanism that leads to intraoperative hypotension (IOH) may vary depending on the stage of anesthesia and surgery, which determines different IOH types. Naturally, the incidence and severity of IOH types will differ, as will the incidence and severity of postoperative complications.

Methods The investigators conducted a data-based observational study that included 4776 patients. Post-induction hypotension (pIOH) is defined as a decrease during the first 20 min after anesthesia induction and maintenance intraoperative hypotension (mIOH) when there is a decrease of blood pressure 20th min after induction, with or without pIOH.

Enrollment: 4,776 patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria
