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 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.

The incidence and clinical picture of non-painful and painful phantom limb sensations as well as stump pain was studied in 58 patients 8 days and 6 months after limb amputation. The incidence of non-painful phantom limb, phantom pain and stump pain 8 days after surgery was 84, 72 and 57%, respectively. Six months after amputation the corresponding figures were 90, 67 and 22%, respectively. ⋯ During the follow-up period the localization of phantom pains shifted from a proximal and distal distribution to a more distal localization. While knifelike, sticking phantom pains were most common immediately after surgery, squeezing or burning types of phantom pain were usually reported later in the course. Possible mechanisms for the present findings either in periphery, spinal cord or in the brain are discussed.

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.
