Haemodynamic effects of pretreatment with metoprolol in hypertensive patients undergoing surgery.

abstract：:For 6 months after renal transplant serum cholinesterase concentrations were measured in 10 patients. The value decreased in the first 15 days after operation, but was normal thereafter. Liver function tests were normal throughout the study; the cholinesterase changes were independent of immunosuppressive therapy. ...
