Pre-and intraoperative predictors of polyneuropathy in patients after cardiac surgery

According to various authors after cardiac surgery the occurrence of neurological complications from the peripheral nervous system varies from 0,1-12%. The etiopathogenesis of peripheral nervous system injuries in cardiac surgery patients is multifactorial and the causes of lesions in each case often remain unclear. The aim of the study was to identify pre-and intraoperative predictors of polyneuropathy in patients subjected to cardiac operations. Material and methods: the 62 patients who were treated at the clinic of thoracic and cardiovascular surgery. Patients who underwent heart surgery and showed signs of polyneuropathy in the postoperative period made up the main group-20 patients. The control group consisted of 40 people. It was made up of patients who also underwent cardiac surgery, but in the postoperative period they had no signs of polyneuropathy. Results: we analyzed such preoperative and intraoperative potential factors as: heart diseases that caused surgery, the severity of the underlying disease, comorbid background, occupational hazards, a history of polyneuropathy, diseases and medications potentially capable of causing polyneuropathy, affecting the development of polyneuropathy, as well as such intraoperative predictors as: type of surgical treatment, time of aortic compression, duration of artificial blood circulation, type of cardioplegia and oxygenator, features of anesthesia, volume of blood loss, body cooling temperature, resuscitation and the presence of iatrogenic complications Conclusions: patients who have after cardiac surgery don’t have pre-and intraoperative predictors of polyneuropathy in the postoperative period...
