Multicenter Study Observational Study
Analgesic, sedative, antipsychotic, and neuromuscular blocker use in Canadian intensive care units: a prospective, multicentre, observational study.
Our aim was to describe analgo-sedation and antipsychotic and neuromuscular blocking drug (NMBD) use in critically ill patients, management strategies, and variables associated with these practice patterns. ⋯ Nearly all MV patients received analgo-sedation. Opioids were used more often than sedatives despite infrequent use of pain scales. Few patients received antipsychotic therapy, but physical restraint was common. Protocol use was poor compared to DSI. Duration of MV predicted the use of either.

When positioning patients with meningocele and meningomyelocele, it is standard practice to avoid direct pressure on the lesions. That caution is intended to prevent injury to neural elements within the lesion and violation of the cerebrospinal fluid space. We herein report an additional hazard of direct intraoperative pressure on such lesions. An adult patient with a lumbosacral pseudomeningocele sustained a cerebral ischemic injury as a consequence of direct pressure on the lesion during general anesthesia. ⋯ In retrospect, the size and leftward extent of the pseudomeningocele were not appreciated preoperatively, and in spite of the care taken, intraoperative pressure was placed on the lesion. This report cautions that intraoperative pressure related to positioning patients with extra-axial lesions containing cerebrospinal fluid (CSF), e.g., meningoceles and pseudomeningoceles, can result in increases in CSF pressure and thereby a reduction in cerebral perfusion pressure sufficient to result in cerebral ischemia.

Randomized Controlled Trial Comparative Study
A randomized placebo-controlled trial of two doses of pregabalin for postoperative analgesia in patients undergoing abdominal hysterectomy.
Acute pain after open abdominal hysterectomy limits the function of patients in the postoperative period, but data regarding the analgesic efficacy of a low dose of pregabalin (75 or 150 mg) have been conflicting. This study was performed to determine if a low dose of pregabalin could decrease postoperative opioid use following abdominal hysterectomy when compared with placebo. ⋯ At the doses used in this study, pregabalin treatment may not be effective in reducing opioid use up to 24 hr postoperatively following abdominal hysterectomy. This trial was registered at www.ClinicalTrials.gov : NCT00781131.
