Central Venous Saturation: A Prognostic Tool in Cardiac Surgery patients

Abstract

Postoperative ScvO(2) can be a valuable tool to predict OD after major cardiac surgeries. Its kinetics should be carefully followed in that setting.

Agreement between Central and Mixed Venous Oxygen Saturation Following Cardiac Surgery

“…Similarly, Nogueira et al [26] suggested that aiming for ScvO 2 value >/= 70% after cardiac surgery decreased postoperative organ dysfunction. Our result showed that using an ScvO 2 value >70% is highly specific to predict SvO 2 of 70% or more.…”

Systematic review of the association of venous oxygenation and outcome in adult hospitalized patients

“…2,9,12,[20][21][22][23][24][28][29][30]40,42,47 In patients undergoing abdominal surgery, ScvO 2 below 70-75% was associated with increased morbidity. The main results of our study were that values of SmvO 2 or ScvO 2 below 55-70% in cardiac patients and in patients admitted to general ICUs were associated with increased mortality, morbidity and length of stay in ICU.…”

“…19,27,43 Association between SvO 2 and morbidity Several studies have furthermore investigated the association between low SvO 2 and morbidity. 20,21,30,42 Consequently, a low SmvO 2 and ScvO 2 has in the majority of studies been associated with increased use of post-operative ventilatory support and increased length of stay in the ICU. Morbidity was seen as increased rates of post-operative stroke, organ dysfunction and major adverse cardiac events.…”

Perioperative interventions and post‐operative outcomes

“…Fluctuations in ScvO 2 after surgery is associated with increased post-operative complications. Therefore it has been suggested to evaluate how per-operative ScvO 2 influences postoperative outcome [97,175].…”
