warmed irrigation solution
Body-temperature saline or lactated Ringer's solution used during open fetal surgery to maintain fetal thermal regulation and tissue hydration.
Full Definition
Warmed irrigation solution refers to sterile crystalloid fluids heated to body temperature (37°C/98.6°F) and used during open fetal surgical procedures to maintain the fetal thermal environment and prevent hypothermia. These solutions, typically normal saline or lactated Ringer's, are continuously applied to exposed fetal parts and the surgical field to simulate the warm amniotic fluid environment. Proper temperature maintenance is critical because fetuses have limited thermoregulatory capacity and can quickly develop hypothermia when exposed to room temperature conditions. The warming systems must maintain consistent temperature and sterility throughout lengthy procedures.
Usage
Usage note: Temperature must be specified and continuously monitored during use.
