Does this woman have an ectopic pregnancy?: the rational clinical examination systematic review.
The rapid identification and accurate diagnosis of women who may have an ectopic pregnancy is critically important for reducing the maternal morbidity and mortality associated with this condition. ⋯ Transvaginal sonography is the single best diagnostic modality for evaluating women with suspected ectopic pregnancy. The presence of abdominal pain or vaginal bleeding during early pregnancy should prompt a transvaginal sonogram and quantitative serum hCG testing.

The effectiveness of perioperative β-blockade in patients undergoing noncardiac surgery remains controversial. ⋯ Among propensity-matched patients undergoing noncardiac, nonvascular surgery, perioperative β-blocker exposure was associated with lower rates of 30-day all-cause mortality in patients with 2 or more Revised Cardiac Risk Index factors. Our findings support use of a cumulative number of Revised Cardiac Risk Index predictors in decision making regarding institution and continuation of perioperative β-blockade. A multicenter randomized trial involving patients at a low to intermediate risk by these factors would be of interest to validate these observational findings.
