About

The perioperative period poses a heightened risk of complications for patients, including hypotension. While the issue of intraoperative hypotension is well-documented in medical literature, the occurrence and causes of hypotension in the post-anesthesia care unit often receive less attention. This phase of postoperative care, however, is vital for ensuring patient stability and preventing severe consequences. Failure to identify and manage a drop in blood pressure can lead to hypoperfusion of critical organs, increasing the risk of morbidity and mortality. The aim of this study is to examine the frequency of hypotension in the post-anesthesia care unit-defined as systolic blood pressure <90 mmHg or a drop of more than 20% from baseline-and to identify factors contributing to its development.

Full description

The perioperative period is a critical time for patients, marked by an increased risk of various complications, including hypotension. While intraoperative hypotension is extensively studied in medical literature, the occurrence and underlying causes of hypotension in the post-anesthesia care unit (PACU) often remain overlooked. This phase of postoperative care is essential for stabilizing the patient and preventing severe outcomes. A failure to identify and adequately address a drop in blood pressure during this time can result in hypoperfusion of vital organs, increasing the likelihood of morbidity and mortality.

Hypotension in the PACU is defined as a systolic blood pressure below 90 mmHg or a decrease exceeding 20% compared to the patient's baseline measurements. The aim of this research is to explore the prevalence of hypotension in the PACU and to analyze the factors contributing to its occurrence. By improving the understanding of this issue, the study seeks to enhance patient outcomes through timely identification and management of hypotension in this crucial phase of care.
