Norepinephrine at Extubation: Challenging the Hemodynamic Safety Paradigm in Critically Ill Patients with Obesity

By MedXY 12/28/2025

A multicenter validation study confirms that low-dose norepinephrine at the time of extubation does not increase reintubation rates in patients with obesity, offering clinicians greater flexibility in weaning strategies for hemodynamically fragile patients.

Higher Blood Pressure Targets in Septic Shock: When More Vasopressors Do More Harm than Good

By MedXY 12/27/2025

A post-hoc analysis of the SEPSIS-PAM trial reveals that while high MAP targets do not provide a universal survival benefit, they significantly increase mortality risk when requiring high norepinephrine doses or failing to resolve microcirculatory dysfunction like skin mottling.

Preventing Post‑Induction Hypotension With Low‑Dose Norepinephrine Reduces Postoperative Complications After Major Abdominal Surgery

By MedXY 11/06/2025

A single‑center RCT found that starting a titrated norepinephrine infusion at anesthesia induction reduced intraoperative hypotension and lowered 30‑day medico‑surgical complications compared with reactive ephedrine boluses in high‑risk abdominal surgery patients.
