Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Succesful surgery
PTH 24 hours after surgery \<150pg/mL
Intraoperative Paratohormone
Three IOPTH determinations were withdrawn: at anesthetic induction (PTH0), 15 minutes (PTH15), and 30 minutes (PTH30) after completion gland resection. Another sample was taken 24 hours after the procedure (PTH24), values \<150pg/mL defined a successful surgery and patients were assigned to the successful or unsuccessful group. IOPTH drop was analyzed to predict successful surgery with drops of 70% and 90% at 15 and 30 minutes.
Unsuccessful surgery
PTH 24 hours after surgery \>150pg/mL
Intraoperative Paratohormone
Three IOPTH determinations were withdrawn: at anesthetic induction (PTH0), 15 minutes (PTH15), and 30 minutes (PTH30) after completion gland resection. Another sample was taken 24 hours after the procedure (PTH24), values \<150pg/mL defined a successful surgery and patients were assigned to the successful or unsuccessful group. IOPTH drop was analyzed to predict successful surgery with drops of 70% and 90% at 15 and 30 minutes.
