Background: The patient-controlled sedation (PCS) allows for rapid individualized titration of sedative drugs. Propofol has been the most widely used IV adjuvant, during the monitored anesthesia care (MAC). This study was designed to compare the sedation quality, side effect and recovery of the propofol alone, and propofol-remifentanil combination, using PCS for breast biopsy.
Methods: Seventy five outpatients, undergoing breast biopsy procedures with local anesthesia, were randomly assigned to receive propofol alone (group P), propofol-25 ug/ml of remifentanil (group PR25), and propofol-50 ug/ml of remifentanil (group PR50), using PCS. Pain visual analogue scores (VAS) and digit symbol substitution test (DSST), Vital signs, bi-spectral index (BIS) and observer assessment of alertness and sedation (OAA/S) score were recorded.
Results: Apply/Demand ratio in the group PR50 had a significant increase over the other groups (P < 0.05). The incidence of excessive sedation and dizziness were significantly more frequent in the group PR50 (P < 0.05). BIS and OAA/S score significantly decreased in the group PR25, PR50 at 15 min after the operation, the end of surgery (P < 0.05). At 5 min after the start of PCS, patients in the group PR25 and PR50 gave significantly less correct responses on the DSST than that of the group P (P < 0.05).
Conclusions: Compared with the propofol alone, intermittent bolus injection of propofol-remifentanil mixture could be used, appropriately, for the sedation and analgesia during MAC. The group PR25 in a low dose of remifentanil has more advantages in terms of sedation and satisfaction because of the group PR50’s side effects.
