Purpose: Dexmedetomidine (DEX) is a sedative agent with minimal respiratory and hemodynamic effects. The present study aimed to evaluate its effectiveness in peritoneal dialysis (PD) catheter insertion. Methods: This single-center retrospective study included patients who underwent PD catheter insertion under spinal anesthesia in our hospital between January 2016 and December 2020. Patients were divided into the DEX and non-DEX groups according the use of DEX. After 1:1 propensity score matching to adjust for age, sex, body mass index, mean blood pressure (BP), and Charlson comorbidity index, we compared operation-related outcomes, including peak numerical rating scale (NRS), occurrence of nausea, vital signs, or operative time between the two groups. Results: Of a total of 44 patients, 9 patients received DEX, and 35 did not. After propensity score matching, each group consisted of 8 patients. Peak NRS was significantly lower (P = 0.003) in the DEX group compared with the non-DEX group. Maximum mean BP during the operation was also significantly lower in the DEX group compared with the non-DEX group (P = 0.020), with no significant differences in minimum mean BP between the two groups (P = 0.831). The DEX group showed a trend of shortened operative time (P = 0.068). There were no significant differences in the occurrence of nausea (P = 1.000). Moreover, there was no clinically important adverse event associated with use of DEX. Conclusion: The use of DEX in PD catheter insertion under spinal anesthesia could safely improve operative analgesia.
