Randomized Controlled TrialThe effect of intravenous administration of dexamethasone on postoperative pain, nausea, and vomiting after intrathecal injection of meperidine.
Different drugs have been used to enhance postoperative neuraxial opioid analgesia and reduce adverse effects. ⋯ Administration of IV dexamethasone prior to intrathecal meperidine injection enhances analgesia and reduces PONV.

Randomized Controlled TrialOndansetron and dexamethasone dose combinations for prophylaxis against postoperative nausea and vomiting.
Patients at high risk of postoperative nausea and vomiting often receive more than one prophylactic antiemetic drug. In this study we sought to determine whether one or more of four dose combinations of dexamethasone and ondansetron was superior in efficacy. ⋯ All combinations were associated with a low incidence of vomiting and rescue treatment, with dexamethasone 2 mg plus ondansetron 2 mg not significantly different to other dose combinations except that groups receiving 2 mg dexamethasone had a more frequent incidence of nausea.

Validation of the Chinese version of pain self-efficacy questionnaire.
Self-efficacy is a person's belief in his or her ability to perform a certain behavior that achieves a desired outcome. Belief in self-efficacy influences the use of pain-coping strategies, physical and psychological function, and rehabilitation outcome in chronic pain patients. We conducted this prospective study to validate the psychometric properties of a Chinese version of the Pain Self-Efficacy Questionnaire (PSEQ-HK). ⋯ PSEQ-HK is a reliable Chinese clinical assessment tool with satisfactory psychometric properties. Our results provided preliminary support for the construct validity of PSEQ-HK in a heterogeneous Chinese population with chronic nonmalignant pain.

Multicenter StudySevere and long-lasting complications of the nerve root and spinal cord after central neuraxial blockade.
Although rare, major complications after spinal and epidural anesthesia do occur. We report the complications after central neuraxial blockade occurring in 2000 in France. ⋯ These findings suggest the influence of underlying spinal conditions in these complications.

Comparative StudySupraventricular arrhythmias in intensive care unit patients: short and long-term consequences.
Supraventricular arrhythmias (SVA), including atrial fibrillation and flutter, are common in surgical and nonsurgical intensive care unit (ICU) patients. There is increased mortality among surgical ICU patients who develop new-onset atrial arrhythmias after noncardiac, non-thoracic surgery. We sought to determine the preadmission and intra-ICU factors associated with the development of new-onset SVA and mortality in these patients. ⋯ New-onset SVA occur frequently in ICU patients and are markers of extremely high in-hospital and 1-yr mortality.
