BSSEE key terms

A staged operative approach in which bleeding and contamination are controlled rapidly, the abdomen is temporarily closed, and definitive repair is deferred until the patient's physiology has recovered in intensive care.

The self-reinforcing combination of hypothermia, metabolic acidosis, and coagulopathy that develops after major trauma or hemorrhage and markedly increases mortality unless hemorrhage control and rewarming are prompt.

A preplanned, protocol-driven scheme for delivering balanced blood components rapidly to a hemorrhaging patient, limiting crystalloid, and monitoring coagulation, calcium, and temperature during resuscitation.

Deliberately accepting a lower-than-normal blood pressure during active hemorrhage, especially penetrating torso trauma, until surgical control is achieved, aiming to limit clot disruption and dilutional coagulopathy.

Organ dysfunction caused by sustained intra-abdominal pressure above about 20 mmHg, producing impaired ventilation, reduced venous return, and oliguria; treatment is decompression, usually by opening the abdomen.

A rapid bedside ultrasound examination of pericardial, perihepatic, perisplenic, and pelvic windows to detect free fluid in an unstable injured patient, guiding immediate operative or further imaging decisions.

A multidisciplinary, evidence-based bundle of perioperative care elements such as carbohydrate loading, opioid-sparing analgesia, early feeding, and early mobilization that shortens length of stay and reduces complications.

Structured estimation of a patient's likelihood of perioperative death or major complications using tools such as functional capacity, frailty scoring, and validated risk calculators to guide shared decision-making.

Intraoperative fluid administration titrated to measured indices of stroke volume or cardiac output rather than fixed volumes, intended to avoid both hypovolemia and interstitial edema.

A defect in the integrity of a surgically created bowel junction that allows luminal contents to escape, presenting with sepsis, peritonitis, or a persistent drain output and often requiring reoperation.

The physical measures that eliminate the origin of an infection, such as draining an abscess, debriding necrotic tissue, or repairing a perforation, without which antibiotics alone usually fail.

Mechanical or functional impairment of intestinal transit causing colicky pain, vomiting, distension, and failure to pass flatus, managed by resuscitation and decompression with surgery reserved for ischemia, strangulation, or failure to resolve.

Compromise of the blood supply to a segment of bowel, typically from a tight hernia or closed-loop obstruction, producing ischemia that mandates urgent operative exploration rather than observation.

Pain arrested on deep inspiration when the examiner's hand presses below the right costal margin, classically reflecting an inflamed gallbladder contacting the examining hand.

Inflammation of the gallbladder usually caused by cystic duct obstruction by a stone, producing right upper quadrant pain, fever, and leukocytosis, treated with antibiotics and early laparoscopic cholecystectomy.

Bacterial infection of an obstructed biliary tree, classically with fever, jaundice, and right upper quadrant pain, requiring antibiotics plus urgent biliary drainage rather than antibiotics alone.

An endoscopic technique that cannulates the biliary and pancreatic ducts to image, extract stones, place stents, or obtain brushings, carrying a recognized risk of post-procedure pancreatitis.

A fluid collection enclosed by a wall of fibrous or granulation tissue that arises after pancreatitis, lacks an epithelial lining, and is drained only if symptomatic, enlarging, or complicated.

Identification and removal of the first draining lymph node or nodes using blue dye and radiotracer to stage the regional basin with less morbidity than complete dissection.

Surgical removal of axillary lymph node levels I and II, used for proven nodal disease or after positive sentinel nodes, and associated with lymphedema and nerve injury.

The combination of clinical breast examination, imaging, and tissue sampling used to evaluate a breast abnormality, since concordant benign results reliably exclude malignancy.

A life-threatening exaggeration of thyrotoxicosis with fever, tachyarrhythmia, agitation, and altered consciousness, treated with beta blockade, thionamides, iodine, steroids, and supportive care.

Damage to the nerve running in the tracheoesophageal groove during thyroid or parathyroid surgery, causing hoarseness from vocal cord paresis and risking airway obstruction when bilateral.

Low serum calcium following total thyroidectomy from parathyroid devascularization or removal, presenting with perioral tingling, cramps, or carpopedal spasm and managed with calcium and vitamin D.

A permanent focal dilation of the abdominal aorta, usually defined as diameter of 3 cm or more, monitored by ultrasound and repaired when large, rapidly expanding, or symptomatic.

Exclusion of an aortic aneurysm by placing a stent graft through the femoral arteries, avoiding a large abdominal incision but requiring lifelong imaging surveillance for endoleak.

Raised pressure within a closed fascial compartment that impairs capillary perfusion and threatens muscle and nerve, presenting with pain out of proportion and requiring urgent fasciotomy.

Air trapped in the pleural space under pressure that shifts mediastinal structures and obstructs venous return, treated immediately by needle or finger decompression before imaging.

Placement of a chest drain to evacuate air or fluid from the pleural space and restore lung expansion, positioned safely above the diaphragm in the triangle of safety.

Irreversible cessation of all brain and brainstem function, determined by strict clinical criteria and confirmatory testing, after which organ donation may be considered with authorization.

The interval an organ is kept cold and without blood flow between procurement and reperfusion in the recipient, a key determinant of early graft function, especially for the liver and lung.

Life-threatening organ dysfunction caused by a dysregulated host response to infection, identified clinically by a rise in the sequential organ failure assessment score in a patient with suspected infection.

Sepsis with persisting hypotension requiring vasopressors to maintain mean arterial pressure and a raised lactate despite adequate fluid resuscitation, carrying high mortality.

A patient's voluntary authorization for a procedure after receiving and understanding information about its nature, purpose, material risks, alternatives, and the consequences of declining.

A structured verbal confirmation by the operating team before induction, before incision, and before leaving theatre that verifies patient identity, site, allergies, equipment, and planned steps.

A clinical judgment that an intervention cannot achieve the intended physiological goal, relevant to decisions about escalating or limiting life-sustaining treatment in critically ill surgical patients.

The pathological assessment of whether tumor extends to the cut edge of a resected specimen, with a positive margin indicating residual disease and generally prompting further treatment.
