Decreased Body Temperature

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...

Cardiopulmonary Resuscitation IV: Pharmacological Management

Cardiopulmonary Resuscitation IV: Pharmacological Management

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiopulmonary Resuscitation I: Adult

Cardiopulmonary Resuscitation I: Adult

Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Methods of reducing fever

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
Pharmacological Methods of Reducing Fever:

Cardiopulmonary Resuscitation III: AED Use

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Introduction Cardiac Emergencies

Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Background:

Mild therapeutic hypothermia (32°C-34°C) is the sole therapy demonstrating improved neurological outcomes post-cardiac arrest in randomized controlled trials.
Successful resuscitation followed by hypothermia yields significant neurological benefits.

Purpose of the Study:

To evaluate the efficacy of mild therapeutic hypothermia in improving neurological outcomes after cardiac arrest.
To elucidate the neuroprotective mechanisms of hypothermia post-ischemia.

Main Methods:

Randomized controlled trial design.
Application of mild therapeutic hypothermia (32°C-34°C) post-cardiac arrest and successful resuscitation.

Main Results:

One additional patient with intact neurological outcome for every six patients treated with mild hypothermia.
Hypothermia protects the brain via reduced metabolism, decreased reactive oxygen species, inhibited excitatory amino acid release, attenuated immune response, and suppressed apoptosis.

Conclusions:

Mild therapeutic hypothermia is a safe and effective neuroprotective strategy after cardiac arrest.
Recommended for unconscious adult patients with spontaneous circulation post-out-of-hospital ventricular fibrillation cardiac arrest.
Further research is warranted to optimize its benefits.
