Metabolic Acidosis in the Surgical Intensive Care Unit: Risk Factors, Clinical Correlates and Outcome. Findings from a High Dependency Heart and Vascular Surgical Center in Nigeria
Background:Metabolic acidosis
(MA) is a common finding on the surgical ward, more so in the intensive care
unit. Diseases affecting the major organ systems of the body and higher grades
of surgery are common risk factors for MA. It is associated with poor treatment
outcome. Aim:To determine the risk
factors and clinical correlates of metabolic acidosis and assess its
relationship with treatment outcome. Methodology: A retrospective
study at the “Tristate Heart and vascular Center” in Ilishan-Remo South west
Nigeria, on patients that had cardiac and vascular surgeries from January 2015 to December 2019. Three hundred and forty two participants took part in the study.
The demographic, clinical and laboratory findings were entered. Statistical
analysis was with Student’s t-test and Chi square. Results: Two hundred and six
males and 136 females were studied. The incidences of metabolic acidosis prior to induction, on
post-operative day one (POD1) and on POD28were 20.7%, 39.8% and 14.1% respectively. Nine (2.6%) participants died during
