Spinal or epidural anaesthesia for elective caesarean section? A Swedish experience.
Ninety seven women undergoing elective lower segment caesarean section were randomly divided into two groups, group 1 received spinal anaesthesia with hyperbaric bupivacaine and group 2 received mepivacaine 20 mg/ml with adrenaline 5 microg/ml via an epidural catheter. All patients were given a preload of Ringer acetate and Macrodex prior to onset of anaesthesia. Ephedrine 5 mg was given if the systolic blood pressure fell below 100 mmHg. ⋯ The Apgar scores at 1 and 5 min were similar in both groups. The results from our study suggest that spinal anaesthesia is a good alternative to epidural anaesthesia for elective caesarean section. A fall in blood pressure, which is equally possible in both groups of patients, should be prevented by adequate fluid preload and treated immediately by intravenous ephedrine.

Numerous postoperative analgesic therapies are continuing to develop as interest increases in the control of acute pain, particularly within the specialty of anaesthesia. Further progress will be made in the near future in relation to preemptive analgesia and reduction of postoperative pain by controlling spinal cord plasticity.(41,42) The concept of multimodal or balanced analgesia(43) in which the combined use of specific agents blocking specific segments of the pain pathway is another area which may provide improvements in postoperative analgesia.

The local anesthetic lidocaine was injected into the dentate gyrus (DG) of alert, unrestrained rats 10 min prior to investigation within the formalin test. Regional anesthesia of the DG resulted in a reduction of pain scores when administered contralateral to the site of subcutaneous formalin injection. The analgesic effect was evident 30-50 min after central infusion. These results provide evidence of the involvement of the hippocampal formation (HF) in pain perception.

ReviewThe role of patient-controlled analgesia in the management of cancer pain.
The technology of patient-controlled analgesia (PCA) has gained wide acceptance for use in cancer pain management. Assessment of technological innovations is necessary in order to evaluate the most appropriate use from the perspective of the individual patient and broader health policy perspective. This paper reviews the literature related to PCA use in chronic cancer pain, appropriate and inappropriate uses of PCA, as well as several professional issues and directions for future PCA use. Professional dialogue regarding the standard of PCA care is necessary for optimum use of this technology for relief of chronic pain.
