Continuing education. Home care of the epidural analgesia patient: the nurse's role.
Spinal analgesia offers a viable alternative for many patients with cancer whose pain cannot be controlled by systemic narcotics. The success of this therapy depends largely on the effectiveness of the home health nurse in instructing patient and caregivers, monitoring catheter care, and assessing the patient's response to treatment.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative cryoanalgesia for postthoracotomy pain relief.
In a randomized study, 63 patients were investigated for the benefits of cryoanalgesia after thoracotomy. Analgesia and its dependent effects such as enhancement of mobility, respiratory function, and reduced need of narcotics were evaluated. ⋯ However, moderate to severe neuralgia was found in a number of patients in the cryoanalgesia group in the late postoperative period. Cryoanalgesia for pain relief after thoracotomy is not recommended.

Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind comparison of epidural ketamine and diamorphine for postoperative analgesia.
Twenty patients who had abdominal hysterectomy under general anaesthesia were randomly assigned to receive either epidural ketamine (30 mg), or epidural diamorphine (5 mg) peri-operatively and on first request for analgesia. Failure to obtain satisfactory analgesia with one of the agents was treated by epidural administration of the other. Pain was assessed by an independent observer, and by the patient using a visual analogue scale. ⋯ The mean (SD) time to first request for analgesia was 272 (206) and 72 (41) minutes in the diamorphine and ketamine groups respectively (p less than 0.01). All patients in the diamorphine group obtained adequate analgesia, but all patients in the ketamine group were changed to epidural diamorphine. Epidural ketamine does not appear to be a sufficiently effective alternative to epidural diamorphine for routine use in postoperative pain.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison between open-end (single hole) and closed-end (three lateral holes) epidural catheters. Complications and quality of sensory blockade.
A randomised, single-blind study was conducted on 802 parturient women who required epidural analgesia, to compare open-end (single hole) with closed-end (three lateral holes) epidural catheters. The complication rate after catheter insertion was not statistically different between the two groups, but the number of unsatisfactory blocks was significantly higher in the open-end group (p less than 0.001). ⋯ This resulted in a significantly higher number of open-end catheters that required replacement (p less than 0.001). Open-end catheters despite their theoretical advantages in the detection of intravenous and subarachnoid placement caused an unacceptably high incidence of unsatisfactory sensory blockade.
