Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia for major abdominal surgery with continuous thoracic epidural infusion of bupivacaine with sufentanil, versus bupivacaine with morphine. A randomized double blind study.
Forty-six patients undergoing major abdominal surgery were given postoperative epidural analgesia for four days with bupivacaine-sufentanil or bupivacaine-morphine. Both groups received a bolus of 8 ml bupivacaine 0.5% followed after 30 minutes by an infusion of 20 ml/h bupivacaine 0.1%. The sufentanil group (group A: 21 patients) received a loading dose of 50 micrograms sufentanil and a continuous infusion of 5 micrograms/h sufentanil. ⋯ There was also a high incidence of hypotension after the loading dose of bupivacaine 0.5%. Although we noticed a large incidence of pruritus, no patient needed naloxone reversal. In view of these side effects we recommend a lower loading dose of both bupivacaine and sufentanil.

Review[Acute pain in surgery: the significance of a neglected problem].
Acute pain represents a significant problem in surgical patients. However, the management of acute pain in Germany is unsatisfactory, mostly because surgeons are not interested in the pain of their patients, and anesthesiologists do not give pain treatment on surgical wards. The aim of this article is therefore to point out the significance of the problem of "acute pain" for surgeons. ⋯ It is not sufficient to know the methods and advantages of appropriate management of acute pain; one must also understand the dangers. Problems caused by the treatment of pain should be recognized from a clinical point of view. Surgeons must take a greater interest in the problem of "pain", which should lead to the establishment of new concepts in the management of acute pain in surgical patients.

Loss of sensation to pinprick and cold are commonly used to test the extent of epidural anesthesia. To see what difference exists between the level of epidural block determined by various sensory modalities, we performed this study in ten volunteers using epidural anesthesia with plain 3% chloroprocaine hydrochloride. ⋯ This study establishes the existence of a differential epidural anesthesia during high thoracic block with chloroprocaine and suggests that the intensity of block diminishes as distance from site of injection increases.

A case of respiratory depression which occurred following administration of epidural meperidine during Caesarean section is described. Epidural meperidine, 75 mg (10 mg.ml-1) was given after delivery of the infant to provide postoperative analgesia. Oxygen desaturation (SaO2 90%) and a decrease in respiratory rate (4.min-1) were noted 30 min after epidural meperidine was administered. ⋯ Vascular absorption of meperidine from the epidural venous plexus is the most probable explanation for this case of early respiratory depression. We recommend a maximum bolus dose of 50 mg of epidural meperidine for pain management after Caesarean section. It is also important to monitor oxygen saturation continuously during the intraoperative period, and to monitor the patient closely in the recovery room for at least one hour for evidence of respiratory depression.
