Categories of pa琀椀ents at higher opera琀椀ve risk (ABCDE)
A- Allergies
o Important to document what it is and what the response is
o Higher risk of hypersensi琀椀vity reac琀椀ons to anesthesia and other meds used in surgery and pre op
B- Bleeding (past history or risk)
o E.g., Pts taking ASAs
o Higher risk for surgicals complica琀椀ons and bleeding
C- cor琀椀sone/ steroids
o Increased risk of emboli
o Impacts ability to heal and reac琀椀on to anesthe琀椀cs
D- diabetes
o Important to iden琀椀fy glucose management plan

o Surgery and post- opera琀椀ve immobiliza琀椀on increases risk of embolus
Major complica琀椀ons
Anaphylaxis
o Typically due to hypersensi琀椀vity reac琀椀on or drug- drug interac琀椀on with other meds
Major blood loss
o Coagula琀椀on issues can occur when pa琀椀ent’s circula琀椀on is slowed due to cold or an an琀椀platelet give
reduce clo琀�ng in surgery
o Mechanical hemorrhage can also occur
Malignant hypothermia
o Rare, inherited, gene琀椀c muscle disease, with no symptoms other than during exposure to certain drugs
o GA can trigger hypercatabolic state (uncontrolled increase in metabolism, leading to hyperthermia,
muscle rigidity/ spasms, and tachycardia) which can be fatal if untreated
o Treat with muscle relaxant and physical cooling
Poten琀椀al problems in the post opera琀椀ve period
Neuro Delayed awakening, increased ICP, cerebral hemorrhage (Cerebral vascular accident/ stroke), post-
opera琀椀ve stroke
Resp Airway obstruc琀椀on, hypoxemia, atelectasis, hypoven琀椀la琀椀on, pulmonary edema, pulmonary embolism,
aspira琀椀on, post-op pneumonia and infec琀椀on
Cardiac Hypotension, hemorrhage, hypovolemia, syncope/ arrhythmias (can be due to the previous 3 things), DVT
(must have through assessment of chest or leg/ calf pain bc of DVT risk)
GI N/V/C, abdominal distension, postopera琀椀ve ileus (usually resolves in 2-3 days), paraly琀椀c ileus (lasts more
than 2-3 days, and is more concerning)
GU Oliguria (<30 mls/hr), anuria (no urine), urinary reten琀椀on, UTI
Wounds Infec琀椀on, dehiscence, eviscera琀椀on

Plasma = 55% of blood, blood cells = 45%
Pancytopenia: en琀椀re CBC is suppressed (RBC, WBC, and platelets)

Hemoglobin Measure of gas carrying capacity of RBCs
LOW: anemia, hemorrhage, hemodilu琀椀on
HIGH: increased O2 carrying requirement due to smoking, living at higher al琀椀tudes, COPD,

dehydra琀椀on, emphysema, heart failure, some cancers
Hematocrit Measure of packed cell volume of RBCs expressed as a percentage of total blood volume (high and
low similar to hemoglobin)
WBC count LOW: autoimmune disorders (e.g., lupus, HIV) malnutri琀椀on, vitamin de昀椀ciencies, TB, medica琀椀on,
cancers
HIGH: infec琀椀on, allergies, stress, steroids
Platelet count LOW: infec琀椀ons, anemia, cancers, medica琀椀ons (e.g., an琀椀bio琀椀cs, an琀椀convulsants, chemo)
pregnancy, autoimmune disorders, TTP (Thrombo琀椀c Thrombocytopenic Purpura)
HIGH: bone marrow disorders, acute bleeding, infec琀椀on, in昀氀amma琀椀on, surgery, trauma
INR How long blood takes to clot
LOW: clot too fast- increased vitamin K, estrogen containing medica琀椀ons,
HIGH: blood thinners, NSAIDs, liver failure, bleeding, vitamin K de昀椀ciency
People on warfarin will have INR of 2-3
aPTT LOW: trauma, cancer
HIGH: pregnancy, hemophilia, DIC, vitamin K de昀椀ciencies, leukemia, sepsis, liver disease
Fibrinogen LOW (decreases ability to clot): DIC,
HIGH: in昀氀amma琀椀on from cancer
Rh is based on D an琀椀gen found on RBC membrane
Rh+ has D an琀椀gen
An Rh- person can be exposed to Rh+ blood which
results in forming an an琀椀body (an琀椀-D)
o 2nd exposure to Rh+ blood will cause severe
hemoly琀椀c reac琀椀on
Anemia
Can result from
o Decreased RBC produc琀椀on
o Blood loss/ hypovolemia
o Increased RBC destruc琀椀on
Early/ middle signs: Hgb= 60-100 g/L, fa琀椀gue, SOB,
Late: Hgb< 60 g/L, lethargy, headache, dizziness, tachy, low BP, SOB,
