Incidence of Hypotension in the Post-anesthesia Care Unit (PACU)

What this Trial Is About

Researchers are studying hypotension, or low blood pressure, that occurs in the post-anesthesia care unit (PACU) after surgery. While low blood pressure during surgery is well known, this study focuses on the frequency and causes of hypotension during the critical recovery phase immediately after surgery. Understanding these factors is important to prevent serious complications like poor blood flow to vital organs, which can increase health risks after surgery. This observational study monitors patients who are over 18 years old and undergoing procedures under general anesthesia. Researchers track blood pressure in the PACU, defining hypotension as a systolic pressure below 90 mmHg or a drop of more than 20% from the patient's baseline. The study collects data on surgery duration, anesthesia type, blood loss, fluid balance, medication use, heart rate, and other factors that may influence blood pressure during recovery. Participants stay in the PACU after surgery where their blood pressure and heart rate are closely monitored. Researchers also observe events such as nausea, vomiting, consciousness levels, oxygen levels, and any transfers to intensive care due to instability. The main outcome measured is how often hypotension occurs in the PACU. The study includes detailed monitoring on the day of surgery and aims to improve care by identifying risks and better managing blood pressure after anesthesia.
