Randomized Controlled Trial Comparative Study Clinical Trial
Perioperative ischaemia in aortic surgery: combined epidural/general anaesthesia and epidural analgesia vs general anaesthesia and i.v. analgesia.
The goal of this randomized study was to determine whether combined general and epidural anaesthesia with postoperative epidural analgesia, compared with general anaesthesia and postoperative intravenous analgesia, reduced the incidence of perioperative myocardial ischaemia in patients undergoing elective aortic surgery. ⋯ Combined general and epidural anaesthesia and postoperative epidural analgesia do not reduce the incidence of myocardial ischaemia or morbidity compared with general anaesthesia and postoperative intravenous analgesia.

Airway management in neurosurgical patients presents unique challenges to the anaesthetist. This review will consider specific approaches to numerous problems in airway management related to logistical, physiological and anatomical concerns. The goal is to provide a clinically oriented and practical discussion regarding issues of airway management in neurosurgical patients. ⋯ The demands for airway management in neuroanaesthesia require expertise in the various modes of securing the airway while considering the patient's physiological requirements as well as the unique surgical demands.

Major breast cancer surgery is associated with a high incidence of postoperative nausea, vomiting and pain. Regional anaesthesia, with intraoperative sedation, would seem an ideal alternative to general anaesthesia for this type of surgery. We report our initial experience using paravertebral blocks (PVB) to provide anaesthesia for major breast surgery. ⋯ Our initial results show that PVB for breast cancer surgery can be successfully performed in a majority of patients with few side effects. All patients with successful blocks were returned to the ambulatory care unit, bypassing the recovery room. That breast cancer surgery under regional anaesthesia can be safely performed as an ambulatory procedure has the potential for accomplishing major cost-saving.

To determine whether a group of experienced clinicians can predict intensive care unit (ICU) length of stay (LOS) following cardiac surgery. ⋯ Experienced clinicians can predict preoperatively with a considerable degree of accuracy patients who will have short ICU lengths of stay following cardiac surgery. However, many patients who had long ICU stays were not correctly identified preoperatively. Unidentified preoperative risk factors or unanticipated intraoperative/postoperative events may be causing these patients to have longer than expected ICU stays.

The study compared analgesic efficacy of intrathecally administered ketorolac tromethamine (K) and morphine hydrochloride (M) (in equimolar doses) in the chronic neuropathic pain model, induced by chronic constriction injury (CCI) of the sciatic nerve in rat. ⋯ M and K produced hypoalgesia after intrathecal administration in rats with CCI, with M being more potent than K at an equimolar dose range. The analgesic effect of K was equal to equimolar doses of M for alleviation of cold allodynia.
