Next step if FAST reveals free intraperitnoeal fluid in abdomen of hemodynamically unstable Pt?
Urgent laparotomy
Management of hemodynamically unstable Pt with suspected intraabdominal trauma.
IV fluid resuscitation and FAST exam. If positive for intraabdominal hemorrhage, then laparotomy. If negative, then stabilize and look for signs of extra-abdominal hemorrhage (i.e. CT scan of abd).
FAST acronym?
Focused assessment with sonography for trauma.
Labs in Gilbert syndrome?
Elevated unconjugated bili (UDP glucuronosyltranferase enzeme deficient)
Normal liver ATs, etc.
Name MC organisms to infect a new prosthetic joint (knee) under 3 months, 3-12 months, or >12 months after surgery.
<3 mo: Staph. Aureus or Pseudomonas
3-12: Coag negative staph (epidermidus) or propionibacterium
>12: Staph. Aureus (often hematogenous spread from distant infxn)
A common postop complication resulting from shallow breathing and weak cough due to pain is?
Atelectasis. Most commonly shows up 2-3 days posop after abd surgery or thoracoabdominal surgery.
Preoperative evaluation of what is required for a patient on long term steroid use (>5mg/day)?
Early-morning cortisol level. Study the risk of Addisonian crisis after surgery.
Management of blunt abdominal trauma in hemodynamically stable patient?
If Alert and talking, do FAST exam. If not go right to CT. If Fast positive or negative gonna end up doing CT anyway.
First step in dangerous hemorrhage?
2 large bore IVs.
Management in suspected variceal hemorrhage in alcoholic?
2 large bore IVs. Fluids, IV octreotide, antibiotics (if cirrhotic). Urgent endoscopic therapy for varices.
Fever, CP, leukocytosis, and mediastinal widening on chest Xray after cardiac surgery may indicate?
Acute mediastinitis. Requires drainage, surgical debridement, and prolonged antibiotic Rx.
Epidural hematoma presentation on CT of head?
Hyperdense biconvex lesion that does not cross suture lines. Requires emergent hematoma evacuation.
How is clavicle fracture managed?
Fractures of the middle third of the clavicle, which are the MC type of clavicle Fx, are treated nonoperatively with a brace, rest, and ice. If Fx occurs in the distal third it may require open reduction and niternal fixation to prevent nonunion. Careful neurovascular exam is required also and if damage to vasculature under the clavicle suspected then angiogram required.
Management of umbilical hernia vs gastroschisis or omphalocele.
Hernia can be monitored for spontaneous resolution by age 5. Immediate surgery for the others.
Contusion or rupture of the neck, anterior wall, or anterolateral wall of the bladder are considered what kind of bladder injury?
Extraperitoneal bladder injury. Often associated with pelvic Fx. Gross hematuria usually present and urinary retention may occur. Injury does not involve leakage of urine into peritoneal space (vs intraperitoneal bladder injury).
Rupture of the dome of the bladder abutting the peritoneum is called what?
Intraperitoneal bladder injury. The dome of the bladder is composed of the superior and lateral bladde walls and directly abuts the peritoneal space. This results in intraperitoneal urine leakage and presents with chemical peritonitis.
In what case are imaging studies needed in acute appendicitis?
Only in nonclassic cases. Otherwise, a classic clinical diagnosis (umbilical pain the moves to RLQ, sharp peritoneual pain, anorexia, NV, mild fever) can be made and laparoscopic surgery performed without need for imaging.
What assessment must be made in a patient with penile fracture first, before surgery?
Urethral injury 2° to retrograde urethrogram. Evidence of urethral injury (blood at meatus, dysurea, retention), need urethrogram.
Duodenal hematoma Rx?
Decompression via NG tube and parenteral nutrition for ~1-2 wks. until resolution.
Placement of a central venous catheter must be confirmed immediately afterward with what method of imaging?
Chest Xray. Observation of tip placement proximal to angle between trachea and right mainstem bronchus confirms proper placement.
Name 5 ways to decrease ICP in head trauma Pt.
Head elevation Sedation Mannitol Hyperventilation Remove CSF
Stress fractures management of metatarsal 2-4 vs 5?
2-4: Requires rest and simple analgesia.
5: May require casting or internal fixation due to nonunion risk.
What common risk presents after burn injury?
Gram+ infxn immediately after injury and gram- infxn more commonly occur after 5 days. A change in wound appearance or loss of graft often indicates infxn of burn wound. Hyperkalemia (EKG required and tele if abnormal) and compartment syndrome also possible (5Ps).
Hypocalcemia and hyperphosphatemia in the presence of normal renal fxn indicates?
Hypoparathyroidism. Often due to post-surgery, autoimmune or non-autoimmune parayhroid destruction or defective calcium-sensing receptors (pseudohypoparathyroidism).
