Summary

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.

Detailed description

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.

Conditions

• Post-induction Hypotension
• Post Anesthesia Recovery
• Hypotension
• Intraoperative Hypotension

Interventions

Type	Name	Description
OTHER	Hemodynamic observation of the patients.	For the purposes of this study, we defined intraoperative hypotension as a decrease in mean blood pressure of 30% from baseline for a minimum of 5 minutes, including induction and maintenance of anesthesia. The measuring blood pressure method (noninvasive or invasive) depended on the surgical intervention's invasiveness and the patient's cardiac performance. As soon as the patients entered the PACU, the responsible nurses started the standard monitoring. Anesthesiologists constantly oversee all actions based on the patient's condition. Clinical observation for respiratory and gastrointestinal problems and all disorders were monitored. When in room air SO2 was \<94, we started oxygen treatment with a 4 liter/minute nasal cannula, and in cases of nausea antiemetic was administered. The Modified Aldrete Score was used to discharge the patent.
