Impact of dexmedetomidine on hyperparathyroidism recurrence in uremic
patients undergoing parathyroidectomy: a retrospective
propensity-matched study
Abstract
Aims Recurrence of secondary hyperparathyroidism (SHPT) remains a big
challenge in uremic patients who underwent total parathyroidectomy with
auto-transplantation (tPTX-AT). However, the relationship between
perioperative intervention and recurrence of SHPT remains unclear.
Dexmedetomidine has been used safely and effectively in uremic patients’
anesthesia. The aim of the study was to explore the effect of
dexmedetomidine on the recurrence of SHPT and speculate the possible
mechanism of action. Methods Records of patients who underwent tPTX-AT
between 2017 and 2018 were retrospectively analyzed. The study consisted
of patients who received dexmedetomidine intra-operatively and the
controls were patients who did not receive dexmedetomidine. The primary
endpoint was the difference in the recurrence of SHPT one year after
surgery between the two groups. The secondary endpoint was
health-related quality of life scores. Analysis included propensity
score matching and multivariable logistic regression. Results Of 354
patients, 133 had received dexmedetomidine intraoperatively, and the
total recurrence rate of SHPT was 10.2%. After propensity score
matching, patients who received dexmedetomidine had a 3.80-fold
decreased risk of SHPT recurrence (odds ratio, 0.263; 95% confidence
interval, 0.081 to 0.854; P=0.026) and exhibited a better quality of
life in terms of physical functioning and general health, and less
emotional role limitations compared with those in control group.
Conclusion In uremic patients who received tPTX-AT, there was an
association between dexmedetomidine use and decreased risk of SHPT
recurrence. However, further studies are needed to accurately assess the
effects and mechanism of action of dexmedetomidine on the prognosis of
this population.
