2.3 Implantation of blood pressure telemetry implant
The rats were injected intraperitoneally with a pentobarbital-normal
saline solution (50mg/kg) for anesthesia before undergoing the
implantation procedure, which involved the following steps: performing
an abdominal incision surgery on the rats and separating their abdominal
aorta; injecting a blood pressure detection probe into the abdominal
aorta and securing it to the abdominal wall; suturing the muscles and
skin and administering subcutaneous injections of meloxicam (1mg/kg) for
pain relief and gentamicin (5mg/kg) for infection prevention; placing
the rats on a constant temperature blanket and feeding them separately
after they regained consciousness. Additionally, subcutaneous injections
of meloxicam (1mg/kg) for pain relief and gentamicin (5mg/kg) for
infection prevention were also administered daily for three days after
surgery.
