ASSESSMENT AND PLAN:
In summary, John Doe is OPTIMIZED for left knee arthroplasty on 15 November 2024 with Dr. Sarah Lee - Orthopaedic Surgery.
In the clinic today, the overall conduct of anesthesia was reviewed with John Doe. The CAS fasting guidelines were discussed.
I've asked John Doe to continue all of their regular medications up until and including the day of surgery with the exception of:
#ASA, hold for 7 days, last day 08 November 2024
#Oxycodone, continue as prescribed pre-op, consider dose reduction post-op
We reviewed the following possible anesthetic types and associated risks.
#General Anaesthesia (GA): Risks of sore throat, nausea and vomiting, dental damage, and remote chance of cardiovascular and respiratory complications.
#Spinal Anaesthesia (Neuraxial): Risks of PDPH at 1%, infection at 1 in 1000, temporary nerve damage at 1 in 10000, permanent nerve damage at 1 in 250000, and failed spinal at 1 in 100.
In terms of access, we spoke about the need for pre-op IV insertion as well as possible:
#Arterial line
I've also asked John Doe to bring the following on the day of surgery:
#CPAP machine
#All current medications in their original bottles
I have ordered the following additional tests, pre-operatively.
#CBC
#Electrolytes and Creatinine
As for pre-op I've gone through the liberty of ordering the patient:
#Gabapentin 300mg PO night before surgery
#Celecoxib 200mg PO morning of surgery
John Doe's questions were solicited and answered. John Doe was made aware that the anesthesiologist on the day of surgery will make the final decision as to the anesthetic plan.
The patient was agreeable to proceed.
