Does patient-controlled sedation with midazolam until the end of surgery improve patient preference compared to sedation only prior to surgery in patients undergoing minor oral surgery?
Patients undergoing minor oral surgery prefer having the option for patient-controlled sedation throughout the procedure rather than only prior to it.
Intra-operative midazolam increments may enhance comfort in third molar surgery; leaves open optimal regimens and applicability to other procedures.
In order to find out whether patient-controlled sedation carried out only prior to surgery was sufficient for patients to undergo minor oral surgery, 30 patients of either sex between the ages of 16 and 30 years were selected. Each was scheduled to undergo bilateral third molar surgery, one side only at a visit. At the first visit each patient was randomly allocated to receive patient-controlled sedation with midazolam either only prior to, or to the end of surgery. At the second visit they received the alternative method of sedation when the operation was carried out on the opposite side. With both techniques the majority of the patients were relaxed and provided good operating conditions with stable vital signs and without loss of consciousness. However, when given the opportunity to sedate themselves until the end of surgery, 70 per cent obtained increments during surgery; four were assessed to have marked sedation and in five the button dropped off. When questioned at the end of both procedures, 87 per cent preferred to have increments during surgery.

Rodrigo et al. (1996) conducted an RCT in minor oral surgery (n=30). Patient-controlled sedation with midazolam until the end of surgery vs. Patient-controlled sedation with midazolam only prior to surgery was evaluated on Patient preference for sedation method. Patient-controlled sedation with midazolam available until the end of minor oral surgery was preferred by 87% of patients compared to sedation only prior to surgery.
