Lipid emulsion as rescue for local anesthetic-related cardiotoxicity.
Regional anesthesia techniques use local anesthetics to provide sensory and motor block for surgical intervention. Intravascular absorption of the local anesthetics may induce toxic effects, such as seizure activity or cardiac depression, leading to cardiac arrest. ⋯ Research in animals, however, has shown that, with the administration of intravenous lipid emulsion, hemodynamic stability can be restored after local anesthetic-induced cardiac arrest. Recent case reports have detailed successful resuscitation from cardiac arrest in several patients with local anesthetic-induced cardiotoxicity.

New approaches to the management of acute perioperative pain have focused on ways to improve the risk/benefit profile of various analgesics, enhance the consistency of pain control, address interpatient differences in responses to pain and treatments, and avoid periods of ineffective pain relief (analgesic gaps). Although intravenous patient-controlled analgesia has been the "gold standard" for acute pain management, there are now more analgesic options and compelling data to support combinations of analgesics or multimodal therapy, timing of analgesic interventions, and the use of newer drug delivery systems. Maximizing pain control with preemptive analgesia and multimodal therapy, and the availability of transdermal fentanyl by iontophoresis and extended-release epidural morphine have expanded the armamentarium of effective options for perioperative pain control. This article explores emerging trends in acute pain therapy, and discusses their implications for improving patient care.

Pain is a predictable consequence of surgery or trauma. Untreated, it is associated with significant physiological, emotional, mental, and economic consequences. ⋯ The significance of these unmet needs is reflected in the number of journal and textbook publications dedicated to disseminating research, evidence-based guidelines, and clinical information. Acknowledging the importance of APM, health care accrediting agencies and professional societies have become increasingly focused on ensuring that patients receive prompt and acceptable pain relief.

ReviewAssessment, physiological monitoring, and consequences of inadequately treated acute pain.
Postoperative pain is a major health care issue. Several factors have contributed to inadequate postoperative pain control, including a lack of understanding of preemptive pain management strategies, mistaken beliefs and expectations of patients, inconsistencies in pain assessment practices, use of as-needed analgesics that patients must request, and lack of analgesic regimens that account for inter-individual differences and requirements. ⋯ To effectively manage postoperative pain, nurses must be able to adequately assess pain severity in diverse patient populations, understand how to monitor physiological changes associated with pain and its treatment, be prepared to address the psychosocial experiences accompanying pain, and know the consequences of inadequate analgesia. It is important for nurses to be aware of relevant research and evidence-based guidelines that are available to guide pain assessments and patient-monitoring practices.
