An emergency is a sudden, unexpected health crisis that threatens life, limb, or organ function, demanding immediate clinical action. Medical emergencies usually stem from internal systemic failures like cardiac arrest, severe asthma, or acute stroke. Surgical emergencies involve acute structural damage or organ failure, such as a ruptured ectopic pregnancy, strangulated hernia, or severe internal bleeding, which typically require operative intervention. Differentiating the two guides whether a patient needs immediate pharmacologic resuscitation or surgical theater preparation. Nurses in Nigerian emergency wards must recognize that many medical conditions can rapidly precipitate surgical crises, and vice versa.
When dozens of patients arrive simultaneously at a busy Nigerian teaching hospital, triage ensures that those with the most time-critical conditions receive care first. The Emergency Severity Index or similar color-coded systems categorize patients into immediate resuscitation, urgent, and non-urgent groups. Nurses perform a rapid primary survey lasting under sixty seconds to identify life threats before conducting a detailed secondary survey. Prioritization relies on objective vital signs rather than social status or order of arrival.
The ABCDE systematic approach provides a universal framework for stabilizing any critically ill patient, regardless of the underlying disease.
Medical emergencies demand quick recognition of organ system failure. Common presentations include acute myocardial infarction manifesting as crushing chest pain radiating to the left arm, acute severe asthma attacks with intercostal recessions, and cerebrovascular accidents presenting with sudden focal neurological deficits. Hypoglycemia can mimic stroke or psychiatric disturbance and must be ruled out immediately using a bedside glucometer. Management focuses on reversing hypoxia, restoring perfusion, and administering condition-specific antidotes or emergency drugs.
Surgical emergencies often present as an acute abdomen—severe abdominal pain of sudden onset requiring urgent surgical evaluation.
Before medical doctors arrive or specialized investigations are completed, nurses initiate vital supportive care. Positioning is critical: an unconscious breathing patient is placed in the recovery position to prevent aspiration, while a patient in shock may benefit from flat positioning with legs slightly elevated. Oxygen therapy must be initiated promptly if oxygen saturation drops below normal thresholds. Nurses also secure peripheral IV lines, collect urgent blood samples for crossmatching and laboratory analysis, and attach continuous cardiac and saturation monitors.
Continuous reassessment prevents deterioration from going unnoticed in emergency settings. Vital signs are recorded frequently on early warning scoring charts to capture upward or downward trends. Accurate documentation must include the exact time of medication administration, fluid intake, and changes in neurological status. When transferring care to the operating theater team or intensive care unit, nurses use structured communication tools like SBAR (Situation, Background, Assessment, Recommendation) to ensure critical details are never omitted.
