The decision to proceed with surgery is serious and mixed with both hope and anxiety. Surgery holds the potential for wonderful benefits balanced with some risk. Patients need to be informed, and to be fully aware of their disease process, their prognosis, and their options.  Our preoperative education classes offered through Saint John’s Nursing are a critical component – educated and informed patients heal better. Patients and families are invited to meet the team of nurses, social workers and therapists who will participate in the postoperative care period. Common concerns related to rehabilitation, home recovery, anesthesia, pain control, and others are addressed in a supportive environment. Questions are answered and preparations for recovery can be made prior to surgery. In this away, much of anxiety and mystery of surgery can be resolved.   Call the office at 310.582.7474 to schedule attendance.
