Complications according to mode of delivery among human immunodeficiency virus–infected women with CD4 lymphocyte counts of ≤500/μL

Objective: We sought to describe rates of and risk factors for complications by delivery mode among human immunodeficiency virus–infected women with CD4 counts of ≤500/μL. Study Design: Complication rates were calculated by delivery mode, as follows: planned cesarean delivery performed without labor or rupture of membranes, other cesarean delivery performed after labor or rupture of membranes, or vaginal delivery. Risk factors were evaluated. Results: Major complications in the planned cesarean delivery (n = 37), other cesarean delivery (n = 95), and vaginal delivery (n = 365) groups were amnionitis or endometritis (16%, 27%, and 7%, respectively), wound infection (5%, 8%, and <1%, respectively), and transfusion (8%, 6%, and 3%, respectively). Any peripartum infection occurred among 16 (18%) of those with a CD4 count of <200/μL and 43 (13%) with a CD4 count of ≥200/μL (P = .17). On multivariate analyses, factors associated with amnionitis-endometritis were cesarean delivery and African American race, and a factor associated with transfusion was third-trimester anemia. Conclusion: Endometritis and wound infection occurred more frequently among human immunodeficiency virus–infected women after cesarean than among women undergoing vaginal delivery; however, complication rates overall were within the range reported in human immunodeficiency virus–negative women. Measures to decrease complications in human immunodeficiency virus–infected women, such as greater use of prophylactic antibiotics, should be assessed. (Am J Obstet Gynecol 2000;183:100-7.)
