OBJECTIVE:

To quantify intrapartum hemorrhage and serum creatinine (Cr) postpartum concentration to calculate its correlation and determine the frequency of acute kidney injury in patients undergoing caesarean section.

MATERIALS AND METHODS:

Cross-sectional and retrospective study carried out in women who ended their pregnancy by caesarean section between January 1 and December 31, 2019 at the Hospital for Gynecology and Obstetrics 3 of the IMSS. The clinical records were consulted to calculate the amount of intrapartum hemorrhage and the value of Cr to determine its correlation and the frequency of acute kidney injury (postpartum Cr >1 mg/dL). Statistical analysis: descriptive statistics, Student’s T test and Pearson’s correlation coefficient (r).

RESULTS:

The mean age was 32.44 ± 7.11 years with gestational age 32.55 ± 4.18 weeks, intrapartum hemorrhage 558.11 ± 570.62 mL and postpartum Cr 0.77 ± 0.21 mg/dL. The correlation of intrapartum hemorrhage vs postpartum Cr was r = 0.158 and obstetric hemorrhage (> 1,000 mL) vs postpartum Cr r = 0.390. The frequency of AKI was 14.03% (16 cases) and dialysis requirements 2.42% (3 cases).

CONCLUSIONS:

The amount of intrapartum hemorrhage was acceptable with low frequency of obstetric hemorrhage. Postpartum Cr increased significantly. The intrapartum hemorrhage vs postpartum Cr correlation was positive which increased its significance as the amount of bleeding increased. Low percentage of acute kidney injury and dialysis requirements was found.
