The effect of epidural morphine on the duration of action of epidural 2-chloroprocaine was studied in a double-blind fashion in 30 patients following elective Caesarean section. When compared to epidural saline controls (n = 15), patients (n = 15) who received epidural morphine (4.0-5.0 mg) did not experience a prolongation or reduction in the duration of the somatic or sympathetic nervous system blockades produced by epidural 2-chloroprocaine.

Randomized Controlled Trial Clinical TrialEffect of transcutaneous nerve stimulation on postoperative pain after thoracotomy.
A prospective randomized double-blind study was undertaken to evaluate the efficacy of transcutaneous nerve stimulation (TNS) in relief of acute post-thoracotomy pain by comparing postoperative narcotic requirements in 22 patients having TNS and in 22 patients having sham electrical stimulation. All patients in both groups had intrathoracic malignancies. When TNS was used, 22.7% of the patients required no narcotics in the first 24 hr postoperatively. All patients having sham stimulation required postoperative narcotics.

Randomized Controlled Trial Comparative Study Clinical Trial
The optimum concentration for epidural fentanyl. A randomised, double-blind comparison with and without 1:200 000 adrenaline.
A randomised, double-blind study comparing a variety of different concentrations of fentanyl with and without 1:200 000 adrenaline is described. It was shown that the quality and duration of analgesia with epidural fentanyl was concentration-dependent below 10 micrograms/ml, but that the addition of adrenaline abolished this phenomenon. The rate of failure to achieve any analgesia was very high with the more dilute solutions, but adrenaline reversed this problem. In general the incidences of side effects were related to the concentrations of fentanyl used and apart from itching, the incidences of these side effects were reduced by the addition of adrenaline.

Randomized Controlled Trial Clinical TrialPost-thoracotomy pain relief: combined use of cryoprobe and morphine infusion techniques.
In a reported study we found that freezing of the intercostal nerves under direct vision at thoracotomy provided better postoperative analgesia than im morphine on demand. Infusions of morphine were also more effective than when used by the intramuscular route. ⋯ Further studies were carried out to evaluate the benefit of combining 'cryoprobe' analgesia with infusions of morphine. The combined use of morphine infusion and a cryoprobe did not produce greater postoperative pain relief than the use of the cryoprobe alone with im morphine on demand.
