A medida do lactato arterial intraoperatório não é determinante de mortalidade em pacientes cirúrgicos de alto risco

Factors affecting a persistent increase in the perioperative lactate levels in colorectal cancer surgery and its impact on postoperative outcomes

“…17,24 In a few studies, similar to our results, the effect of persistent high lactate levels on survival has not been demonstrated. 6,25 One of the strengths of the study is that the research included repetitive measurements in lactate measurement instead of just a single blood sample. The lactate values measured before completion of the surgery were supported by four following measures in the early postoperative period, and the relationship between different variables and persistent elevations was investigated.…”

“…4 Lactate is not only an indicator of tissue hypoxia but also of poor postoperative outcomes and is often used today in the follow-up of critical patients. 5 In contrast, Junior et al 6 states that intraoperative hyperlactatemia does not have prognostic significance.…”
