ABSTRACT

Objective To investigate the risk factors of renal inadequacy after postpartum hemorrhage. Methods According to the diagnostic criteria of postpartum hemorrhage, 200 cases of postpartum hemorrhage who were admitted to the Intensive Care Unit from January 2010 to December 2014 were collected. The general situation, history of pregnancy induced hypertension and gestational diabetes mellitus, ASA classification, anesthesia method, delivery mode, postpartum hemorrhage and other indicators. The risk factors were analyzed by logistic regression.Results Among 200 cases of postpartum hemorrhage who were admitted in the intensive care unit, 21 cases with renal insufficiency were seenafter delivery (10.5%) aged between 20 and 44 years old with the average age of (29.24 ±4.58) years old. Using the ASA evaluation criteria to evaluate the preoperative situation, we observed179 cases in ASA grade levelⅠ (89.5%), 20 casesin level Ⅱ (10%), one casein level Ⅲ (0.5%) and no case in grade Ⅳ. Among all the women, we found 147 cases of vaginal delivery (73.5%), 53 cases of cesarean section (26.5%),196 cases of spinal anesthesia (including labor analgesia) (98%) and 4 casesof general anesthesia (2%) . There were 12 patients with hypertension during pregnancy (6%), and 188 patients without hypertension (94%) . There were 9 cases of gestational diabetes mellitus (4.5%), and 191patients without gestational diabetes mellitus (95.5%).Conclusions The risk factors of renal insufficiency after postpartum hemorrhage were age older than 35 years, cesarean delivery, pregnancy history of hypertension or gestational diabetes mellitus.
