Changes of plasma moderate molecule substance concentration in pediatric patients during open heart surgery / 中华麻醉学杂志

ABSTRACT

Objective:To investigate the changes of plasma moderate molecule substance (MMS)level in pediatric patients with congenital heart disease during open heart surgery. Method: Siteen cases were studied. Blood samples were taken before anesthesia, after tracheal intubtion, after sternotomy. and rewarming during cardiopulmonary bypass, to measure the plasma MMS levels with ultraviolet absorption spectrophotometry. Result: As compared with that before anesthesia, the MMS levels after tracheal intubtion,sternotomy,and rewarming during cardiopulmonary bypass were significantly elevated(P
