ABSTRACT
Tranexamic acid (TA) act as anti-fibrinolytic agent and is widely used to limit bleeding in clinical practice. Tranexemic acid bind with plasminogen and prevent its conversion to plasmin, which limits the fibrinolytic pathway, so there is a theoretical risk of increasing thrombosis with high or prolonged therapy with TA. We encountered a case of acute arterial thrombosis following inadvertent administration of high dose of TA. A 27-years-old male with no other co-morbidity was ordered intravenous 1 gm TA to control excessive bleeding from previous bladder injury, but by mistake, he received 10 gm of TA. The patient developed signs and symptoms of acute ischemia in the right lower limb, which was diagnosed as acute iliac arterial thrombosis by computed tomography (CT) angiography. The patient was managed with systemic heparinization, fasciotomy for impending gangrene and other supportive care following which he recovered fully within a few days. Caution should be exercised for all prophylactic use, especially with high dosage or prolonged therapy with TA.
ABSTRACT
Poor neurological outcome is a common sequel of prolonged cardiac arrest. Although Therapeutic Hypothermia (TH) for neuroprotection has been a subject for research for over Half a century, its use has been limited because of many controversies and lack of clear guidelines. However for over two decades there has been a revival of interest in mild therapeutic hypothermia (32-34°C) for neuroprotection. However its use after primary asystolic cardiac arrest has been questioned. Herein presenting two cases of prolonged asystolic arrest (39 minutes and 25 minutes); where therapeutic hypothermia was successfully used in following prolonged cardio pulmonary resuscitation. On patients who were in deep coma after resuscitation, TH was applied for 24 hours as per institutional protocol with full neurological recovery in both the cases. Therapeutic hypothermia might have a potential role in even in non-shockable arrests and should be considered in every successful cardiopulmonary resuscitation with poor neurological status.
