Brief Answer: These symptoms vary patient to patient. Detailed Answer: Hi, I have read your problem. You must know that every surgical procedure has some risks and benefits. Your individual results will depend on your personal circumstances, and recovery takes time. You should not get worried for all this i.e blood pressure and oxygen level, but, be careful for symptoms and discus it with your doctor. These complications are rare during or right after elective joint surgery, in part because most patients are "tuned up" for surgery and optimized after obtaining presurgical medical clearance. A small percentage of patients may experience low blood pressure (hypo-tension) and low oxygen level during or right after surgery. So your wife is in those small percentage of patients. Risks are different for different people- Some patients can spontaneously develop a cardiac arrhythmia after surgery, often for reasons that are unclear. This may require monitoring in the telemetry unit until the symptoms disappear. Rarely, this may require treatment with either blood thinners or electric cardioversion by the cardiologist. Some patients develop Congestive Heart Failure i.e heart has difficulty keeping up with the pumping demands, and fluid begins to back up into the lungs because the heart is not pumping as strongly as it should. This is usually treated with fluid restrictions, diuretics ("water pills"), and cardiac medications prescribed by the cardiologist to help the heart pump more strongly. Similarly some patients develop-Blood Clots,Fat Emboli etc. All that is needed is continuous monitoring of patient and timely consultation by physician and operating surgeon. I thing you have get your answer. You are welcome to ask further health related query. Thanks. Dr.Singh.
