Study Notes

Cervical spine should be considered unstable in certain situations, including clinical examination revealing bony abnormalities or tenderness, multisystem trauma, blunt injury above clavicle, altered level of consciousness from trauma or drugs, and maxillofacial trauma.
Immobilization of the cervical spine is done using a backboard and rigid collar or manual in-line immobilization if not available.
Radiological evaluation of the cervical spine is done later after stabilization of vital systems.
Breathing is assessed by inspecting for air movement, respiratory rate, cyanosis, tracheal shift, jugular venous distention, open chest wounds, asymmetric chest expansion, use of accessory muscles of respiration, palpating for subcutaneous emphysema and flail segments, auscultating for upper and lower airway sounds, and cervical spine immobilization.
Immediately life-threatening thoracic conditions and their treatment include tension pneumothorax, needle decompression followed by intercostal chest tube, cardiac tamponade, needle pericardiocentesis followed by operative pericardiotomy and control of bleeding source, flail chest, emergency pleural cavity drainage, and massive haemothorax, initial treatment by chest tube insertion and later thoracotomy if bleeding continues.
Shock is categorized into haemorrhagic, cardiogenic, and neurogenic.
Bleeding is controlled with direct pressure, large-calibre IV lines, blood sampling, and fluid resuscitation.
Neurological assessment is done using AVPU evaluation and Glasgow Coma Scale.
Clothes are removed using sharp scissors and the patient is kept warm, a urinary catheter is inserted if not contraindicated, and a nasogastric tube is used to decompress the stomach and prevent vomiting and aspiration.
Radiological assessment includes cervical spine, AP chest, pelvis, and trauma site X-rays or CT scans.
Patient's history is obtained during the primary survey using the acronym AMPLE.
Secondary survey is done once resuscitation efforts are underway and preliminary X-rays have been evaluated, with objectives being a thorough examination of the patient and taking a complete medical history.
Severe haemorrhage can be caused by traumatic injuries, such as splenic or liver injury, haemothorax, pelvis fracture, or major surgery. Other causes include bleeding from oesophageal varices, duodenal ulcer, ruptured aortic aneurysm, pre- and postpartum haemorrhage, and ruptured ectopic pregnancy.
Haemorrhage occurs when red blood cells escape from vessels, and is classified by site (external or internal) and type of vessel (arterial, venous, or capillary).
Primary haemorrhage occurs at the time of trauma, while reactionary haemorrhage occurs within 24 hours due to an insecure ligature or dislodged clot, and secondary haemorrhage occurs one to two weeks later due to infection eroding a vessel wall.
Aetiology of haemorrhage can be traumatic, iatrogenic, atherosclerotic, inflammatory, neoplastic, or due to bleeding diathesis.
General surgery response to hemorrhage involves stopping the bleeding locally through vasoconstriction, platelet plug, and blood clotting. Systemically, it involves neural and endocrine responses to maintain effective circulatory volume and perfusion of critical tissues.
Neural responses include stimulation of the sympathetic system, resulting in constriction of veins and arterioles, increased heart rate and myocardial contraction, and increased release of catecholamines and metabolic hormones.
Endocrine responses include release of catecholamines, increased ACTH, cortisol, growth hormone, and glucagon, and inhibition of insulin release.
The renin-angiotensin-aldosterone system is also involved in maintaining effective circulatory volume and perfusion by releasing aldosterone and vasopressin.
Symptoms of haemorrhage include weakness, fainting, feeling cold and thirsty, mental status changes, pulse and blood pressure changes, respiratory distress, hypothermia, and oliguria.
Clinical estimation of blood loss can be made by assessing mental status, skin colour and capillary refill, pulse and blood pressure, respiratory rate, and urine output.
Estimated blood volume is 70 ml/kg in adults and 80 ml/kg in children, and losses up to 15% of blood volume can be compensated for by the body's mechanisms.
Common signs of haemorrhage include pale, cold, and clammy skin, slow capillary refill, hypotension, tachycardia, and tachypnea.
Haemorrhage can be fatal if a large artery is involved, such as the carotid artery after a radical neck dissection.
Haemorrhage can be caused by various factors, including trauma, atherosclerosis, inflammation, neoplasia, and bleeding diathesis.
Haemorrhage can be classified based on site (internal or external) and type of vessel (arterial, venous, or capillary).
The body responds to haemorrhage through local and systemic mechanisms, including vasoconstriction, platelet plug, blood clotting, neural responses, and endocrine responses.
Neural responses include stimulation of the sympathetic system, release of catecholamines, and inhibition of the vagus nerve.
Endocrine responses include release of ACTH, cortisol, growth hormone, glucagon, and vasopressin.
The renin-angiotensin-aldosterone system is involved in maintaining effective circulatory volume and perfusion by releasing aldosterone and vasopressin.
Clinical estimation of blood loss can be made based on symptoms, signs, and measurements of blood loss, mental status, skin colour and capillary refill, pulse and blood pressure, respiratory rate, and urine output.
Haemorrhage can be life-threatening if a large artery is involved, such as the carotid artery after a radical neck dissection.
The body's response to haemorrhage involves local and systemic mechanisms to stop the bleeding and maintain effective circulatory volume and perfusion.
