Study information

Study design	A randomised cross-over prospective trial.
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Treatment
Scientific title	-
Study objectives	To assess the safety and effectiveness of patient-controlled sedation with midazolam compared with the currently used technique of operator-controlled sedation with midazolam in healthy patients undergoing surgical removal of lower third molars.
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Surgical removal of impacted third molars
Intervention	N = 64 (+ 20% to allow for drop-outs) p = 0.05; power 0.8; effect size 0.3; tests: repeated measures t-test (normal distribution) or Wilcoxon signed ranks test (non-parametric). Patients are randomised to: 1. Patient-controlled sedation with midazolam 2. Operator-controlled sedation with midazolam
Intervention type	Drug
Pharmaceutical study type(s)
Phase	Not Specified
Drug / device / biological / vaccine name(s)	Midazolam
Primary outcome measure	1. Demographic, medical and dental status 2. Duration of sedation induction and operation 3. Level of sedation (score at 10, 20, 30 minutes following the end of the procedure) 4. Operating conditions 5. Vital signs 6. Anxiety assessment (by asking the patients to indicate their level of anxiety on a visual analogue scale [VAS] - 100 mm) 7. Memory and acceptability - once recovered, patients are asked whether they can remember specific events during the appointment. Following the second appointment, patients are asked to specify which session provided the most acceptable level of sedation and anxiolysis.
