Type of obstetric anesthesia administered and complications in women with preeclampsia in low- and middle-income countries: A systematic review.

BACKGROUND

Delivery is often expedited with cesarean section, necessitating anesthesia, to prevent complications in women with preeclampsia. Anesthesia-associated risks in these women from low- and middle-income countries (LMICs) are not known.

METHODS

We searched major databases (until February 2017) for studies on general vs. regional anesthesia in women with preeclampsia. We summarized the association between outcomes and type of anesthesia using a random effects model and reported as odds ratio (OR) with 95% confidence intervals (95% CIs).

FINDINGS: We included 14 studies (10,411 pregnancies). General anesthesia was associated with an increase in the odds of maternal death sevenfold (OR 7.70, 95% CI 1.9 to 31.0, I2 = 58%) than regional anesthesia. The odds of pulmonary edema (OR 5.16, 95% CI 2.5 to 10.4, I2 = 0%), maternal intensive care unit admissions (OR 16.25, 95% CI 9.0 to 29.5, I2 = 65%), and perinatal death (OR 3.01, 95% CI 1.4 to 6.5, I2 = 56%) were increased with general vs. regional anesthesia.

CONCLUSION

General anesthesia is associated with increased complications in women with preeclampsia undergoing cesarean section in LMIC.
