This systematic review and meta-analysis evaluated the efficacy and safety of nonselective alpha-blockers (NAB) versus selective alpha-blockers (SAB) for preoperative preparation in patients with pheochromocytomas and paragangliomas (PPGL). Involving 2293 patients across 20 studies, NAB significantly reduced the risk of intraoperative hypertensive crisis (OR: 0.33) and maximum systolic blood pressure (MD: -12.85 mmHg) compared to SAB.
Key findings
- NAB significantly reduced the risk of intraoperative hypertensive crisis (OR: 0.33, P < .001).
- Maximum intraoperative systolic blood pressure was lower with NAB (MD: -12.85 mmHg, P < .001).
- Intraoperative vasopressor use was less frequent in the NAB group (OR: 0.60, P = .02).
- NAB maintained a higher minimum systolic blood pressure (MD: 2.02 mmHg, P = .008).
Why it matters
Understanding the comparative effectiveness of NAB and SAB is essential for optimizing preoperative management in patients with PPGL, as it can significantly impact intraoperative hemodynamic stability and patient outcomes.
