The most common laboratory abnormality noted in these patients is metabolic acidosis secondary to a lactic acidosis. If obtained, the workup should be directed towards the patient’s history and exam (eg for continued hypoxia a chest x-ray and blood gas may be warranted or for altered mental status a head CT, blood glucose, blood gas, toxicology analysis, ethanol level, and a metabolic panel may be needed). Labs and/or imaging studies are not always warranted in well-appearing, normoxic, asymptomatic patients. The hypoxemia also induces ventricular arrhythmias and severe pulmonary hypertension. Cerebral edema followed by autonomic instability often results followed by ST-segment changes, indicating stress-related myocardial damage. #Panic cord g fresh download freeGlobal CNS hypoperfusion induces releases of excitotoxic neurotransmitters, free radicals, and lipid peroxidation. Within 2 minutes most victims lose consciousness and within 4-6 minutes will develop irreversible brain injury. The two major sequelae of drowning are to the CNS and cardiac system. These victims seldom aspirate any fluid and are said to have dry drowning. Additionally, current recommendations state that routine use of cervical spine immobilization and imaging is not warranted unless the history or exam suggests that the patient suffered from a traumatic injury.Īt least 20% of individuals develop tight laryngospasm that lasts even after cardiac arrest. It is more important to note if the fluid was obviously contaminated (sewage), as those patients are highly prone to pulmonary infection and prophylactic antibiotics may be warranted at presentation. Volume or serum (electrolyte) changes only occur when a significant volume of fluid is aspirated. ĭetermination of the toxicity of the water that the victim was immersed in (eg saltwater versus freshwater) is of little importance in non-fatal drowning. Interestingly, hypothermic exposure with the incident may be tissue-protective, although may result in an increased occurrence of cardiac dysrhythmias. The highest morbidity and mortality are related to cerebral hypoxia, and management is aimed at reversing hypoxia as quickly as possible. This can result from minor to no respiratory complaints to fulminant non-cardiogenic pulmonary edema, with a clinical picture similar to adult or acute respiratory distress syndrome (ARDS). Aspirated fluid can lead to surfactant washout and dysfunction, increased permeability of the alveolar-capillary membrane, decreased lung compliance, and ventilation/perfusion ratio mismatching. When a person suffers from submersion or immersion in a liquid medium, vital tissues may become hypoxic and acidotic which may result in cardiac dysrhythmias (progressing from tachycardia, bradycardia, pulseless electrical activity, and asystole). Even those who survive may develop a vegetative state due to the prolonged cerebral hypoxia. Hypoxemia and acidosis need to be corrected immediately if mortality is to be avoided. The most immediate threat in drowning is dysfunction of the cardiac and CNS systems. In many cases, cold water can be protective especially in children. In most cases, a motionless individual floating in water who rapidly disappears beneath the surface is the classic scenario.ĭrowning can occur in both warm and cold water. Individuals who thrash wildy in water while drowning are rare. Drowning usually occurs in a rapid fashion and is most often silent. ĭrowning is a major public health problem, especially in children. Wet drowning, dry drowning, and near-drowning are no longer accepted terms, although they may still be used when discussing drowning. To delineate the incident's outcome, this is further divided into descriptive terms such as death, morbidity, and no morbidity. Drowning is defined as a process of experiencing respiratory impairment from submersion/immersion in a liquid medium. ![]()
