Critical care anaesthesia is a specialized branch of medicine focusing on the management of critically ill patients requiring surgical or medical interventions in intensive care settings. It involves advanced skills in airway management, hemodynamic monitoring, ventilatory support, and pain control. Anesthesiologists in this field manage complex medical conditions such as sepsis, multi-organ failure, acute respiratory distress syndrome (ARDS), and traumatic injuries. They employ techniques like invasive monitoring, renal replacement therapies, and sedation for prolonged care. Critical care anaesthesiologists also play a vital role in managing postoperative patients in the ICU, ensuring stability and recovery.
