Clinical TrialMixed venous oxygen saturation during mobilization after cardiac surgery: are reflectance oximetry catheters reliable?
Oximetry catheters immediately reflect changes in mixed venous oxygen saturation (SvO2). We have used the Baxter 2-SAT system to register changes in SvO2 during early mobilizations after cardiac surgery. To assess catheter reliability, readings were compared to blood gases. ⋯ The two methods are interchangeable for most clinical purposes. Catheter readings are, however, substantially lower than the corresponding haemoximetric measurements at low SvO2 values. Careful interpretation of the absolute values resulting from catheter measurements is recommended, especially when SvO2 readings are low.

Thoracic epidural anaesthesia and analgesia: United Kingdom practice.
Thoracic epidural analgesia has become increasingly practised in recent years. Complications are rare but potentially serious and, consequently, careful evaluation is required before undertaking this technique. The practice surrounding this procedure varies widely amongst anaesthetists. ⋯ In the United Kingdom, there is little consensus in the practice of thoracic epidural analgesia relating to the issues of informed consent, epidural cannulation in patients with deranged clotting and the sterile precautions taken prior to performing epidural insertion. Most respondents use an opioid-based bupivacaine solution to provide postoperative epidural analgesia. Most hospitals in the UK now provide an acute pain service for thoracic epidural follow-up.

Randomized Controlled Trial Comparative Study Clinical TrialOnset and offset of intrathecal morphine versus nalbuphine for postoperative pain relief after total hip replacement.
We designed this study to compare the postoperative analgesic effects of intrathecal morphine and nalbuphine, the endpoints being onset and offset of action. ⋯ We conclude that after total hip replacement, administration of intrathecal nalbuphine resulted in a significantly faster onset of pain relief and shorter duration of analgesia than intrathecal morphine.

Randomized Controlled Trial Clinical TrialRandomised, placebo-controlled study of the postoperative analgesic effects of ketoprofen after spinal fusion surgery.
The additive effect of non-steroidal anti-inflammatory drugs administered with propacetamol after major orthopaedic surgery has not been studied. Thus, we performed a prospective, placebo-controlled study to assess the analgesic effects of ketoprofen in patients undergoing spinal fusion surgery and receiving propacetamol. ⋯ Ketoprofen reduced morphine requirements and improved postoperative analgesia in patients undergoing major spinal surgery and receiving propacetamol.
