Pain management in the postanesthesia care unit (PACU) is continually evolving, with several new nonopioids expanding the list of available agents. Pain in the PACU is not an inevitable outcome of surgery. With careful planning, multimodal analgesic techniques instituted preoperatively will reduce pain in the PACU. Accurate assessment of the characteristics(More)
BACKGROUND Concerns have been raised about the use of point-of-care (POC) glucose meters in the hospital setting. Accuracy has been questioned especially in critically ill patients. Although commonly used in intensive care units and operating rooms, POC meters were not approved by the Food and Drug Administration for such use. Data on POC glucose meter(More)
STUDY OBJECTIVE To describe the root causes of intraoperative hypoglycemic events. DESIGN Retrospective analysis. SETTING Large academic teaching hospital. MEASUREMENTS Data from 80,379 ASA physical status 1, 2, 3, 4, and 5 surgical patients were reviewed. Blood glucose values, insulin, oral hypoglycemic medication doses, and doses of glucose or other(More)
BACKGROUND Continuous interscalene blocks provide excellent analgesia after shoulder surgery. Although the safety of the ultrasound-guided in-plane approach has been touted, technical and patient factors can limit this approach. We developed a caudad-to-cephalad out-of-plane approach and hypothesized that it would decrease pain ratings due to better(More)
SUMMARY Uncontrolled postoperative pain may result in significant clinical, psychological, and socioeconomic consequences. Not only does inadequate pain management following surgery result in increased morbidity and mortality but it also may delay recovery, result in unanticipated readmissions, decrease patient satisfaction, and lead to chronic persistent(More)
The coexistence of diabetes, hypertension, obesity, and dyslipidemia is defined as metabolic syndrome. Studies show substantial cardiovascular risks among these patients. The risk of patients with metabolic syndrome undergoing total joint arthroplasty (TJA) is unknown. Patients with and without metabolic syndrome undergoing TJA during a 3-year period were(More)
Management of acute postoperative pain is important to decrease perioperative morbidity and improve patient satisfaction. Opioids are associated with potential adverse events that may lead to significant risk. Uncontrolled pain is a risk factor in the transformation of acute pain to chronic pain. Balancing these issues can be especially challenging in(More)
High-dose opioid administration is associated with significant adverse events. Evidence suggests that low-dose ketamine infusions improve perioperative analgesia over conventional opioid management, but usage is highly variable. Ketamine's adverse drug effects (ADEs) are well known, but their prevalence during low-dose infusions in a clinical setting and(More)
BACKGROUND Perioperative hypothermia may increase the incidences of wound infection, blood loss, transfusion, and cardiac morbidity. U.S. national quality programs for perioperative normothermia specify the presence of at least 1 "body temperature" ≥35.5°C during the interval from 30 minutes before to 15 minutes after the anesthesia end time.
