Risk factors for hysterectomy in abnormal placentation at the University District Hospital.

The aim of this research was to study the relationship of abnormal placentation and cesarean hysterectomy risk factors at the University District Hospital.

METHODS

A retrospective study was conducted using 60 medical records of patients in the University District Hospital from 2001 to 2008 with a diagnosis of abnormal placentation. Descriptive statistics and chi square for associations were used for statistical analysis.

RESULTS

The mean age in our population was 29 years and mean BMI was 29.6. 45 % of the patients had a previous history of cesarean, 1.7% of placenta previa and 26.7% of uterine curettage. We found that 33.3% had a cesarean hysterectomy and 41.7% had post-partum hemorrhage. Also 51.7% received blood transfusion. The mean hospital stay was 18.1 days. The probability of cesarean hysterectomy in patients with placenta previa was eleven times higher in patients with history of previous cesarean sections (OR 11, CI: 1.29-97.9, p value=0.01). There was no statistically significant difference in cesarean hysterectomy rate between obese (BMI>30) and nonobese patients (OR 3.8 CI: 0.69-20.5, p value=0.11).

CONCLUSIONS

The probability of cesarean hysterectomy in patients with abnormal placentation was significantly increased in patients with previous cesarean sections. By decreasing the rate of cesarean section we can decrease the incidence of cesarean hysterectomy and its comorbidities.
