As of 11 a.m. PDT, Friday, Aug. 9, Maria Teresa and Maria de Jesus Quiej Alvarez remain in critical condition with stable vital signs in the Pediatric Intensive Care Unit (PICU) at UCLA’s Mattel Children’s Hospital in Westwood. Both girls, who remain under sedation, continue to show movement and response to stimulation. Doctors plan to begin administering nutrition intravenously today to the sisters. Doctors remain cautiously optimistic about their long-term prospects for recovery. The twins, conjoined at birth, were separated early Tuesday, Aug. 6, in a nearly 23-hour surgery.
