ReviewPharmacology of cyclooxygenase-2 inhibitors and preemptive analgesia in acute pain management.
NSAIDs have served as analgesic, antiinflammatory, and antipyretic medicines for over a century. A novel class of NSAIDs, cyclooxygenase-2 inhibitors, was introduced in 1999. All NSAIDs and aspirin inhibit active sites of cyclooxygenase-1 and cyclooxygenase-2. Recent studies have demonstrated an important role of cyclooxygenase-2 inhibitors in the management of acute pain processes. ⋯ On the basis of many human studies, one may conclude that perioperative cyclooxygenase-2 inhibitors, in standard doses, decrease opioid consumption. Future investigations that include different multimodal techniques, for example combining cyclooxygenase-2 inhibitors with regional blocks, may help elucidate and clarify the true benefits of perioperative cyclooxygenase-2 inhibitors in acute pain management strategies.

The purpose of the present review is to focus on the literature in the past year and specifically the development of recent guidelines, the debate on who does the sedation anaesthesia for MRI in a paediatric patient, the use of medications and techniques, and the use of monitors and equipment. ⋯ The MRI suite is a challenging environment for anaesthetists and nonanaesthetists, and has serious risks. A systematic approach, similar to that of anaesthesia provided in the operating room, is mandatory. A well equipped anaesthesia machine, standard monitoring, trained personnel and adequate planning should be standard for all procedures out of the operating room.

ReviewPerioperative management including new pharmacological vistas for patients with pulmonary hypertension for noncardiac surgery.
Pulmonary hypertension is a condition that has a multitude of causes. Left untreated, patients with pulmonary hypertension will experience progressive symptoms of dyspnea and right heart failure resulting in significant morbidity and mortality. This review details the many evolving aspects of understanding related to pulmonary hypertension including signs and symptoms, pathophysiology, classification, anesthetic management including perioperative considerations and treatment options. ⋯ Coupled with aggressive use of improved diagnostic hemodynamic monitors perioperatively, these patients can be medically optimized during their hospitalization and possibly aid in improving their long-term prognosis.
