Anesthetic Approaches

The Anesthesia

Immunizations – For non-emergent cases, make sure patient has had vaccinations for streptococcus pneumonia, haemophilus influenza type B, and meningococcus infections 2 weeks prior to surgery.

Pulmonary function – watch for left lower lobe atelectasis if the patient has splenomegaly or postoperatively if there will only be a partial splenectomy.

Immune thrombocytopenic purpura (ITP) – If patient has ITP with a low platelet count, do not infuse platelets until the spleen has been removed from the blood circulation (splenic artery and vein have been ligated). Otherwise the spleen will consume all the platelets before circulating in the body.

Arterial Line – If the case is NOT emergent, you probably do not need an A-line, unless there are high concerns for hemodynamic stability (eg. bleeding, heart conditions, etc).

High blood loss risk – Though these cases do not typically result in high blood loss, there is a high risk. Type and cross, CBC, and CMP should be done prior to the procedure. Consider having an A-line, blood tubing, and extra push-lines. Depending on the fragility of the patient, you may want to have blood in the room and available. A cell saver may be employed if there is increased bleeding.

Chemotherapy Patients – It’s relatively common to have patients that are on chemotherapy drugs. Bleomycin, Methotrexate, and cytarabine can cause pulmonary fibrosis. Doxorubicin can cause pleural effusion, CHF, or cardiotoxicity (obtain an ECHO to assess heart function in these patients).

Arterial line (general considerations): Preoperatively check pulses to gauge the best side to attempt the A-line. Perform an Allen test to ensure adequate blood flow. Have the A-line equipment set up and ready in the room.

The Pathophysiology

Typical indications for a splenectomy include leukemia (Hodgkins, non-hodgkins), Idiopathic Thrombocytopenia purpura (ITP), tumors, and cysts.

The Surgery

Emergent – typically due to trauma/bleeding, usually will be a midline incision for quick access to the spleen.

Non-emergent/elective – usually laparoscopic, sometimes open if spleen is enlarged.
