Impact of outpatient preanesthetic consultation on perioperative outcomes in 700 urological patients in a tertiary hospital: a retrospective observational study.
Observational study in Brazilian journal of anesthesiology (Elsevier). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOutpatient preanesthetic consultation improves patient assessment and anesthetic planning, enhancing safety and reducing complications. Conducted in advance, it allows systematic, individualized planning. Uncontrolled hypertension, common in 60% of people over 60, is a major cause of surgery cancellation and increases cardiovascular risk. This study evaluates its impact on preventing perioperative complications and optimizing clinical and surgical outcomes in urological patients.
methodsThis retrospective observational study analyzed 700 patients (≥ 18 years) who attended outpatient preanesthetic consultation before urological surgery. Clinical conditions, systemic blood pressure, heart rate was analyzed during outpatient, preoperative, and intraoperative periods. Preoperative and intraoperative complications were recorded to evaluate consultation impact.
resultsAmong 700 patients (89.6% male, mean age 64.2), ASA II was most common classification. Hypertension was identified in 53.7% of patients during outpatient evaluation. All hypertensive patients received antihypertensive treatment until surgery, with blood pressure maintained within normal limits. Preoperative findings in the operating room included hypertension (2.0%), anemia (0.57%), atrial fibrillation (0.14%), and asthma (0.14%). Intraoperative events included hypertension (2.28%), hypotension (8.14%), bradycardia (1.14%), and inadequate neuraxial block (2.85%). One surgery was canceled due to hypertension. Blood pressure significantly decreased preoperatively and intraoperatively compared to outpatient values (p < 0.0001). Heart rate also decreased significantly intraoperatively. This single-center study has limitations, including absence of comparison groups assessed by other specialties or only day of surgery.
conclusionReductions in systolic and diastolic blood pressure were documented upon operating room entry among patients evaluated in outpatient preanesthetic consultation, with a very low surgery cancellation rate.
