Randomized Controlled Trial Comparative Study
Protamine Dosing for Heparin Reversal Following Cardiopulmonary Bypass: A Double-Blinded Prospective Randomized Control Trial Comparing Two Strategies.
Drug shortages are a frequent challenge in current clinical practice. Certain drugs (e.g., protamine) lack alternatives, and inadequate supplies can limit access to services. Conventional protamine dosing uses heparin ratio-based calculations for heparin reversal after cardiopulmonary bypass and may result in excess protamine utilization and potential harm due to its intrinsic anticoagulation. This study hypothesized that a fixed 250-mg protamine dose would be comparable, as measured by the activated clotting time, to a 1:1 (1 mg for every 100 U) protamine-to-heparin ratio-based strategy for heparin reversal and that protamine would be conserved. ⋯ A 1:1 heparin ratio-based protamine dosing strategy compared to a fixed 250-mg dose resulted in the administration of a larger total dose of protamine but no difference in either the initial activated clotting time or the amount postoperative chest-tube bleeding.

Randomized Controlled TrialMagnesium and Esophageal Pain After Peroral Endoscopic Myotomy of the Esophagus: A Randomized, Double-Blind, Placebo-Controlled Trial.
Postoperative esophageal pain occurs in 67% of patients after peroral endoscopic esophageal myotomy (POEM). Magnesium can act as a smooth muscle relaxant. This study investigated whether intraoperative magnesium can reduce postoperative esophageal pain in patients undergoing POEM. ⋯ Patients undergoing POEM randomized to receive intraoperative magnesium had sustained reductions in esophageal discomfort severity and opioid requirements 24 hours after surgery.
