A community in San Diego is mourning the sudden death of 9-year-old Silvanna Moreno, who passed away just hours after undergoing a dental procedure under anesthesia. The incident, which occurred on March 18 at Dreamtime Dentistry in Vista, has raised concerns about the risks associated with pediatric dental sedation and the rare complications that can arise even in seemingly routine cases. So what do we actually know about child anesthesia risks?
The Procedure and Immediate Aftermath
Silvanna, a third-grader described as healthy and regularly examined, was referred for dental surgery due to acute anxiety and the complexity of her dental needs. The procedure, which lasted approximately three hours, involved root canals, crowns, fillings, and extractions. She was placed under general anesthesia, including the administration of nitrous oxide. Nitrous Oxide is commonly known as laughing gas, along with a combination of other anesthetic drugs.
Discharge and Sudden Decline
Following the procedure, Silvanna was moved to a recovery room where she was monitored until she was awake and had stable vital signs. She was described as “out of it” and mumbling, but able to stand. After being discharged into her mother’s care, Silvanna fell asleep in the car on the way home and continued to sleep upon arrival.
Discovery and Emergency Response
Later that afternoon, Silvanna’s family found her unresponsive in bed. Emergency services were called, and her grandmother was instructed to perform chest compressions while waiting for paramedics. Silvanna was rushed to Rady Children’s Hospital in San Diego. Despite resuscitation efforts, she was pronounced dead at 5:44 p.m..
Medical Examiner’s Findings – Child Anesthesia Risks
An autopsy conducted by the San Diego County Medical Examiner’s Office revealed that Silvanna died from methemoglobinemia. This is a rare blood disorder that impairs the ability of red blood cells to deliver oxygen to body tissues. The condition was linked to the recent administration of nitrous oxide during her dental procedure, with additional contributing factors, including the use of multiple anesthetic drugs.

Understanding Methemoglobinemia
Methemoglobinemia is an uncommon but potentially life-threatening disorder, sometimes referred to as “blue baby syndrome.” It can be inherited, but more often occurs due to exposure to certain medications or chemicals, such as nitrous oxide. The disorder leads to a bluish or purplish tint in the skin, lips, or nails and can cause severe hypoxia if not recognized and treated promptly.
Dentist’s Response and Protocols
Dr. Ryan Watkins, the anesthesiologist at Dreamtime Dentistry, expressed deep sadness over the incident. He emphasized that Silvanna showed no signs of distress or abnormal oxygen levels during or after the procedure. He stated that if any warning signs of methemoglobinemia had been detected, the procedure would have been halted and emergency measures taken. The practice maintains that all standard protocols for pediatric anesthesia and monitoring were followed.
Broader Concerns and Investigation
Silvanna’s death has prompted renewed scrutiny of the risks associated with pediatric dental sedation. Experts note that children are more sensitive to anesthesia than adults, requiring careful dosing and monitoring. The dentist involved had previously faced disciplinary action related to anesthesia administration in a separate incident, though there is no indication of wrongdoing in Silvanna’s case.
Community Grief and Calls for Awareness
The tragic loss of Silvanna Moreno has left her family and community devastated. While her death has been ruled accidental, it underscores the importance of awareness regarding rare anesthesia complications in children. The dental practice has extended its condolences and pledged full cooperation with ongoing investigations, as the community seeks answers and hopes to prevent similar tragedies in the future.
