Comprehensive Notes on General Surgery and Triage Protocols

Emergency Room Triage Categories and Definitions

The classification of patients in the Emergency Department (Instalasi Gawat Darurat or IGD) is essential for prioritizing care based on the severity of the patient's condition. The triage system is divided into four primary color-coded categories: Red, Yellow, Green, and Black. Each category represents a specific level of urgency and physiological stability.

Category Red (Merah) is defined as a critical emergency situation where the patient experiences life-threatening problems related to the Airway, Breathing, or Circulation (ABC). These patients require immediate intervention to prevent mortality or severe morbidity. In contrast, Category Yellow (Kuning) refers to patients who are in a serious or urgent condition but remain physiologically stable. An example of a Category Yellow case is a patient presenting with severe abdominal pain and high fever while maintaining stable vital signs. Although the condition is urgent, it does not immediately compromise the ABCs unlike Category Red.

Category Green (Hijau) encompasses patients who are stable and are often referred to as "walking patients." These individuals have minor injuries or illnesses that do not require immediate or intensive emergency intervention. Finally, Category Black (Hitam) is reserved for patients who are classified as Death on Arrival (DoA). This indicates that the patient has already passed away by the time they reached the medical facility.

Primary Survey and the XABCDE Protocol

In the management of trauma and emergency patients, the primary survey follows the XABCDE sequence. The component "X" stands for the control of exsanguinating hemorrhage. This refers to the immediate control of massive, life-threatening external bleeding. Prioritizing the control of massive bleeding before addressing the airway (A) is a critical shift in modern trauma protocols to prevent rapid exsanguination.

The "X" component involves identifying and stopping catastrophic external bleeding that could lead to shock or death within minutes. Other components of the survey, such as checking the level of consciousness using the Glasgow Coma Scale (GCS), fall under subsequent steps like Disability (D), rather than the initial hemorrhage control phase.

Management of Compressible Hemorrhage

Compressible hemorrhage is defined as a type of bleeding that is visible and accessible for manual intervention. Indicators of compressible hemorrhage include continuous blood flow, a significant pool or puddle of blood, or spurting arterial bleeding. Effective management of these injuries depends on the depth and response of the wound to initial pressure.

For a deep wound classified as a compressible hemorrhage, the initial management involves applying direct pressure using gauze. If the wound is deep enough, "wound packing" is performed by filling the wound cavity with gauze to create internal pressure against the bleeding vessels. Once the bleeding is successfully controlled through these manual methods, the follow-up management is the application of a pressure dressing to maintain hemostasis.

In cases where the bleeding remains uncontrolled despite direct pressure and wound packing, a tourniquet must be utilized. The clinical standard for tourniquet application is to place it approximately $5-8\,\text{cm}$ above the site of the injury (proximal to the wound). It is important to note that the tourniquet should not be placed directly on the wound itself, but rather at a specific distance above it to effectively occlude the arterial blood supply.

Non-Compressible Hemorrhage and Internal Injuries

Non-compressible hemorrhage refers to bleeding that cannot be managed through manual pressure or external packing because the source is located within internal body cavities. This type of bleeding is generally not visible to the naked eye upon initial inspection. Common sites for non-compressible hemorrhage include the thoracic cavity (chest), the abdominal cavity, and the pelvic region.

These injuries often involve damage to internal organs such as the liver (hepar) or spleen (lien). Unlike superficial or external arterial bleeds, these internal hemorrhages require advanced medical imaging, surgical intervention (such as a cito or emergency laparotomy), or specialized procedures because they cannot be reached by external compression methods. Recognizing the signs of internal bleeding in the chest, abdomen, or pelvis is vital for the survival of trauma patients who may appear stable but are losing blood internally.
