Study Notes
Sure! Here is an expanded version of the preoperative testing algorithm, including more detail on the types of diagnoses:
Preoperative Testing Algorithm
-
Patient History a. Medications b. Allergies c. Past surgical history d. Current health status (HTN, DM, CAD)
-
Physical Exam a. Vital signs b. Respiratory exam c. Cardiac exam d. Neurological exam
-
Lab Tests a. CBC (complete blood count) b. BMP (basic metabolic panel) c. PT/INR (if patient takes coumadin) d. PTT (partial thromboplastin time) e. Blood type and cross (if blood transfusion possible)
-
Imaging Studies a. Chest X-ray (for lung surgery) b. EKG (if patient has history of cardiac disease) c. Echo (if patient has history of cardiac disease)
-
Consultations a. Cardiology (if patient has history of cardiac disease) b. Pulmonology (if patient has history of pulmonary disease) c. Nephrology (if patient has history of renal disease)
-
Specialized Testing a. EEG (if patient has history of seizures) b. EMG (if patient has history of neuromuscular disease) c. PFTs (pulmonary function tests, if patient has history of pulmonary disease)
-
Urinalysis a. Dipstick b. Microscopic exam
-
Other a. Blood cultures (if patient has fever) b. Pregnancy test (if patient is of childbearing age)
-
Final Assessment a. Review of all test results b. Physician assessment of patient's overall health status c. Determination of anesthesia plan d. Discussion of risks and benefits of surgery with patient
Please note that this algorithm is a general guide and may need to be tailored to the individual patient's specific needs. It is important to consult with the operating surgeon and anesthesia team to determine the appropriate tests and consultations for each patient. Additionally, institutional protocols and guidelines should be followed.
Explore a comprehensive guide to preoperative testing, covering patient history, physical exam, lab tests, imaging studies, consultations, specialized testing, urinalysis, and final assessment. Learn about the importance of reviewing test results, physician assessment, anesthesia planning, and discussing surgery risks and benefits.
