Acil Serviste Prosedürel Sedasyon ve Analjezi
Synopsis
Procedural sedation and analgesia (PSA) in the emergency department is a standard method aimed at relieving pain, anxiety, and discomfort while preserving the patient's cardiopulmonary functions during diagnostic or therapeutic interventions, as well as providing patient comfort and motion control. Sedation levels are categorized based on clinical response and cardiopulmonary status into minimal, moderate, dissociative, deep sedation, and general anesthesia. Prior to the procedure, patients' existing comorbidities, airway patency risk, substance use, and pregnancy status must be evaluated, and informed consent must be obtained after explaining the procedure and potential adverse effects. Commonly preferred sedative and analgesic agents in the emergency department, such as propofol, ketamine, etomidate, midazolam, fentanyl, and nitrous oxide, should be selected by considering their onset times, duration of action, hemodynamic stability, and potential complications like respiratory depression or hypotension. Synergistic drug combinations like ketofol can balance adverse effects by reducing the required total dose. While transmucosal routes provide alternatives in pediatric patients, maternal hypotension must be prevented and teratogenic drugs strictly avoided in pregnant patients. Continuous vital monitoring and the availability of resuscitation equipment are mandatory during PSA. Following the procedure, patients must be closely monitored until their protective reflexes, level of consciousness, and respiratory functions fully recover and discharge criteria are met. In conclusion, the experience of the healthcare team administering PSA in advanced life support and airway management plays a critical role in reducing morbidity and mortality.
