Relationship Between Bedside Ketone Levels and Time to Resolution of Diabetic Ketoacidosis: A Retrospective Cohort Study.

ABSTRACT:

Introduction

There is no information on the factors that influence the time required to induce resolution of diabetic ketoacidosis (DKA). New methods are currently available for bedside measurement of serum 3-hydroxybutyrate (3HB). The aim of this study was to determine the relationship between serum 3HB and the time to DKA resolution.

Methods

We reviewed the medical records of patients with type 1 diabetes (T1D) and a history of DKA who were admitted to the Department of Pediatrics, Osaka City University Hospital, between November 2008 and October 2018. DKA resolution was defined as 3HB below 1.0 mmol/L as measured by a bedside ketone meter.

Results

Data of 52 T1D-DKA episodes were analyzed (median age, 8.0 years; 20 male patients; 32 female patients; new T1D diagnosis, n = 13; established diagnosis, n = 39). In all cases, correction of serum 3HB was an important aspect of T1D management. The median time to DKA resolution (defined as the time from the start of insulin infusion until the fall of 3HB level to below 1.0 mmol/L) was 11 and 10 h in new and established T1D cases, respectively. 3HB on admission and the required insulin infusion dose per body weight, but not blood pH level on admission, correlated with time to DKA resolution. There was no relationship between blood pH level and 3HB on admission.

Conclusions

Our results showed that DKA resolution could be achieved within 10-11 h when DKA treatment is guided by bedside 3HB monitoring without any severe complications. Blood 3HB level is a potentially suitable marker for the severity and resolution of DKA.
