Postoperative hypotension in patients recovering from noncardiac surgery: a prospective, blinded observational study

Br J AnaesthPublished Prospective observational study

Authors' conclusion

During recovery from noncardiac surgery, postoperative hypotension is common, but rarely severe or prolonged. The incidence of postoperative hypotension progressively decreases from postoperative day 1 to day 3.
