PHYSICIAN INSTRUCTIONS FOR PRE-OP STUDIES
NEW STATE OF THE ART PRE-OP AND BARIATRIC ASSESSMENT STUDIES OFFERED WITH REALLOCATION OF SLEEP BEDS AS OF JULY 2010. PRE-OP PSG REFERRAL
When apnea is suspected in a patient who is to undergo general anesthesia, a sleep study (PSG) may be ordered pre-operatively to ascertain the severity of sleep disordered breathing and the need for treatment in the post-surgical period.
Pre-op PSGs are usually requested by pre-op departments of the major Hamilton and surrounding area hospitals, although we accept referrals from surgeons as well. We request that the PRE-OP PSG REFERRAL is used including the surgical procedure, date of surgery, and symptoms leading to the referral. Patient demographics are essential including a contact number where your patient can be reached at short notice. Your patient will be sent to a CPAP company for overnight oximetry. Depending on the results of the ONO either a sleep study or consultation will be scheduled.
With the allocation of three beds for pre-op patients, we anticpate a turn-around time of 10 working days to complete the two sleep studies (if CPAP is required). A further three days to get your patient set up on CPAP and acclimatized to the equipment before surgery is beneficial.
If CPAP is recommended after a diagnostic study, either an in lab CPAP or Auto PAP study will be done. CPAP setup with a home care company will be arranged by our office prior to surgery and the patient is strongly encouraged to use CPAP for at least 3 days prior to surgery to reduce airway swelling and to encourage compliance in the post-operative period. The patient is instructed to take his or her CPAP machine to hospital and to ask for it to be used post-operatively.
A follow up consultation with a sleep specialist in our clinic is booked following surgery.
