Emergent Reversal of Antithrombotics and Treatment of Life-Threatening Bleeding from Coagulopathies: A Clinical Review.

BACKGROUND: Reversal of antithrombotic agents and treatment of life-threatening bleeding episodes from coagulopathies can be a stressful scenario for clinicians, especially when the selection of treatment options should occur quickly. Understanding the options available for these agents requires emergency physicians to be familiar with the current data surrounding new therapies and dosing strategies for the treatment of bleeding from reversible and nonreversible antithrombotics and coagulopathic conditions. OBJECTIVE: To provide quick resource guides for the reversal of major or life-threatening bleeding caused by antithrombotic agents or in the setting of coagulopathies. METHODS: A literature search for articles published through September 2021 related to antithrombotic reversal and treatment of acute bleeding from coagulopathies was conducted using the PubMed clinical database. Selected articles were used to generate 5 guidance tables in this clinical review. DISCUSSION: Four guidance tables for how to treat major or life-threatening bleeding from antithrombotic agents and 1 table for how to manage life-threatening bleeding for coagulopathies are presented as a quick reference tool for the emergency physician. Additional information on upcoming reversal agents and possible treatment options are provided herein. CONCLUSIONS: In this clinical review, a series of 5 tables were created to provide quick and comprehensive guidance for the emergency physician when treating major or life-threatening bleeding caused by antithrombotic agents or coagulopathies. © 2022 Elsevier Inc.

The emergent reversal of coagulopathies encountered in neurosurgery and neurology: a technical note.

It is imperative for neurologists, neurosurgeons, and neurointensivists to know how to stop life-threatening hemorrhage in both surgical and non-surgical patients. However, knowing how to medically correct a coagulopathy has become increasingly challenging as more contemporary and sophisticated anticoagulation agents are developed and prescribed. In a time-sensitive and life-threatening situation, where there is little margin for error, the neurosurgeon may not have ready access to information about the drug or condition that caused the coagulopathy or the information on how to treat it. This thorough review of the literature provides a comprehensive overview of the medications and conditions that can lead to persistent and/or life-threatening intracranial hemorrhage.

Prazosin treatment of nightmares related to posttraumatic stress disorder.

OBJECTIVE: To describe current data evaluating the use of prazosin in adults with posttraumatic stress disorder (PTSD) who are experiencing nightmares. DATA SOURCES: A literature search using MEDLINE (1966-March 2007) and the Published International Literature on Traumatic Stress database (1982-March 2007) was conducted using the search terms alpha-antagonist, alpha-blocker, prazosin, and posttraumatic stress disorder. References of identified articles were reviewed for additional citations. STUDY SELECTION AND DATA EXTRACTION: All English-language articles regarding the use of prazosin in adults with nightmares related to PTSD were reviewed. DATA SYNTHESIS: PTSD is a psychiatric disorder that develops in some people after exposure to trauma. Sleep disturbances occur in up to 70% of patients with PTSD. Several neurotransmitters have been implicated in the pathophysiology of sleep disturbances in PTSD. Adrenergic agents that inhibit norepinephrine, such as prazosin, may decrease the arousal produced by norepinephrine in response to a stressor. Four open-label studies, 1 retrospective chart review, and 2 placebo-controlled trials reporting the use of prazosin for nightmares related to PTSD were reviewed. All studies included a small number of patients (4-59) and evaluated prazosin dosages ranging from 1 to 20 mg/day. Despite various limitations, all of the studies showed significant improvements in the sleep-related symptoms of PTSD following the addition of prazosin therapy, based on the Clinician Administered PTSD Scale recurrent distressing dreams item and the Clinical Global Impression of Change scale. CONCLUSIONS: Prazosin appears to be a promising and fairly well tolerated agent for the management of PTSD-related nightmares and sleep disturbances. Further well designed trials are warranted to establish its place in therapy.
