Randomized Controlled Trial Clinical Trial
Epidural anaesthesia as a method of pre-emptive analgesia for abdominal hysterectomy.
The effect of pre- versus postincisional epidural blockade without the use of systemic opioids was investigated in a randomised, double-blind study of two groups of 25 patients undergoing abdominal hysterectomy performed under general anaesthesia. The first group received, via a lumbar epidural catheter, 0.9% saline (16 ml) 15 min prior to surgical incision and 0.5% bupivacaine (15 ml) and fentanyl 50 micrograms (1 ml) 15 min prior to skin closure. ⋯ Visual analogue pain scores and patient-controlled morphine consumption were measured at specified times for 48 h. We were unable to detect any significant difference in either of the outcome measures of the two groups and thus were unable to demonstrate that epidural blockade using local anaesthetic and opioid has a pre-emptive effect.

Randomized Controlled Trial Clinical Trial
The effect of ketamine pretreatment on propofol injection pain in 100 women.
A controlled, randomised double-blind study was performed to compare the prior intravenous administration of ketamine 10 mg (1 ml) or 0.9% saline (1 ml) on propofol injection pain. One hundred patients of ASA status 1 or 2 presenting for gynaecological surgery were studied. Following an initial 5-ml bolus of propofol into a dorsal hand vein, 30 s after the treatment, 84% of the saline control patients experienced mild or severe pain compared to 26% of those who were given ketamine pretreatment (p < 0.05).
