Factors that contribute to postoperative lumbar back pain and the effect of an inflatable lumbar support on the incidence of postoperative backache were examined. The study consisted of two parts, a pilot study in which mathematical models for appropriate support pressures were produced and the main study to assess the role of an inflatable lumbar support. The use of a support reduced the incidence of back pain on the first postoperative day from 46 to 21 per cent (P = 0.007). ⋯ Postoperative back pain was more severe after procedures lasting more than 40 min. Early mobilization reduced the amount of back pain. In conclusion, patients benefit from the use of an inflatable lumbar support if they have previously suffered from backache or if they are to be anaesthetized for more than 40 min.

A retrospective study was carried out to determine analgesic requirements in a group of orthopaedic outpatients (n = 145) and oral surgery inpatients (n = 172). The orthopaedic patients received a codeine-paracetamol premedication, an opioid during operation, or no analgesic. ⋯ In the patients undergoing oral surgery, ibuprofen administered before operation significantly reduced analgesic requirement, without unwanted side effects. The use of codeine-paracetamol or a non-steroidal anti-inflammatory agent before body surface surgery appeared to be advantageous in reducing postoperative analgesic needs, without causing problems associated with the stronger opioids.

Epidural sufentanil was administered to 57 women after Caesarean section, under epidural anaesthesia, to provide postoperative analgesia. Each patient received a 30 micrograms dose at the first complaint of pain and this dose was repeated when pain recurred. Epinephrine (1:200,000) was added to the local anaesthetic, sufentanil, both, or neither. ⋯ Respiratory depression, as defined by a respiratory rate less than 10 bpm, was not observed. A number of patients noted a transient period of euphoria 5-8 min after administration of the epidural sufentanil. The authors feel that epidural sufentanil provides satisfactory analgesia after Caesarean section, but the brief duration of action and the high incidence of drowsiness limit its acceptability for routine use in obstetric patients.

Randomized Controlled Trial Comparative Study Clinical Trial[Postoperative peridural analgesia via catheter following abdominal surgery. Peridural bupivacaine versus buprenorphine].
Seventy-five patients scheduled for major abdominal operations were randomly divided into four groups, each with a different postoperative analgesic regime. Group I: buprenorphine 4 micrograms/kg was injected i.v. every 4 h. Groups II-IV: all patients were preoperatively supplied with a thoracic epidural catheter that, however, was not used during the operation. ⋯ No patient in any of the other groups, however, was dropped (P less than 0.01). Later in the 1st postoperative day analgesia in groups II and IV lost its superiority at rest, but coughing continued to be less painful in comparison to groups I and III. We noticed that the duration of action of 0.25% bupivacaine, injected as a bolus, was considerably shorter than expected (less than 2 h) and that several patients experienced pain before the next top-up was given...
