Metabolic Acidosis Patients at Twice the Risk for
Mortality in Intensive Care Units
A study published in today’s journal, Critical Care, shows that patients
with certain types of metabolic acidosis are almost twice as likely to
die as those that do not have the abnormal acidic blood PH.
The risk is especially true for patients that suffer from lactic
acidosis and for patients that have a strong ion gap (SIG) acidosis.
Both of these types of patients need to be monitored more carefully when
admitted to an intensive care unit (ICUs).
Kyle Gunnerson from Virginia Commonwealth University and colleagues from
the University of Pittsburgh researched 851 patients that were suspected
as having metabolic acidosis and were admitted to the ICUs of the
University of Pittsburgh Medical Center. After careful analysis 548
patients were diagnosed with metabolic acidosis while 303 patients did
not have the condition.
The 548 patients that had metabolic acidosis there were 44 percent that
had lactic acidosis, followed by 37 percent having SIG acidosis. The
remaining patients had hyperchloremic acidosis which is another type of
acid/base disorder. The overall rate of mortality for patients with
metabolic acidosis was 45 percent. The patients that did not have the
condition had only a 26 percent mortality rate. The highest percentage
of mortality was with the lactic acidosis patients. They had a 56
percent mortality rate. Mortality rate for SIG acidosis was 39
percent. The hyperchloremic acidosis mortality rate was similar to
those that did not have the metabolic acidosis. This group only had a
29 percent mortality rate.
The researchers recommend strongly that critically ill patients with
metabolic acidosis be monitored and watched for this condition.
