Hemodynamic Effects of Spinal Anesthesia in HIV-Positive Pregnant Women

At the 19th World Congress of the Societies of Anaesthesiologists (WCSA 2026) in Marrakesh, TopMedTalk welcomes Desiree Chappell back alongside Kate Leslie to interview Professor Palesa Motshabi-Chakane , Associate Professor and Head of Anaesthesiology at the University of the Witwatersrand and her colleague, Dr Mullai Slave a PhD candidate at University of the Witwatersrand. They discuss a study of 629 women undergoing cesarean section with spinal anesthesia at Chris Hani Baragwanath Hospital, where 23–33% are HIV positive. Using standard monitoring plus BD APM noninvasive continuous hemodynamic monitoring, they compared HIV-positive and HIV-negative patients and found higher hypotension incidence in HIV-positive women (68% vs 64%), with lower heart rate and lower cardiac index over 60 minutes. Additional testing included echocardiography with speckle tracking, pro-BNP, and autonomic assessments, with HIV-positive patients showing stiffer ventricles; Apgar scores did not differ. They discuss replication, multicenter research, and potential machine-learning tools to predict hypotension risk, and describe BD Advanced Patient Monitoring grant support enabling equipment, sensors, staffing, and training (~200 staff) to complete data collection in about six months. Edwards Lifesciences is now known as Becton Dickinson Advanced Patient Monitoring (BD APM).
