ReviewBronchoscopic treatment of end-stage chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is a progressive, debilitating disease that in its final stages cripples the patient. The disappointing results of the National Emphysema Treatment Trial study led to a decrease in the acceptance of lung volume reduction surgery as a therapy. Thus, it became clear that debilitated COPD patients would need innovative alternative nonsurgical procedures to potentially alleviate their symptoms. This review will address the various techniques of bronchoscopic lung volume reduction (BLVR). ⋯ BLVR appears to be safer than surgery and presents an attractive alternative for the treatment of COPD patients. Unfortunately, the outcome data to date are inconclusive; the procedures remain experimental and any benefits unproven. However, the data that are emerging continue to appear promising.

Chronic pain after surgery is a major public health problem and a major concern for perioperative physicians. Thoracic surgery presents a unique challenge, as thoracotomy is among the highest risk surgeries to develop persistent postsurgical pain. The purpose of this review is to discuss the relevance of research in pain epigenetics to patients with persistent pain after thoracic surgery. ⋯ The transition from acute to chronic pain after thoracic surgery may be mediated by epigenetics. Here, we discuss epigenetic modifications that have been discovered in animal models of chronic pain that may predispose patients to persistent neuropathic pain after thoracic surgery.

Addiction to alcohol and illicit drugs occurs in approximately 10% of the Canadian population and thus likely affects numerous perioperative patients. Provision of perioperative analgesia to these patients is challenging for physiological and behavioural reasons. Seven electronic databases were searched to identify papers addressing the perioperative management of analgesia in addicted patients. ⋯ Perioperative analgesic management of addicted patients remains poorly understood. Most clinical trials specifically exclude addicted patients. Suggestions for management are provided.

Acquired pharmaco-dynamic opioid tolerance: a concept analysis.
To report an analysis of the concept of acquired pharmaco-dynamic opioid tolerance. ⋯ Untangling the antecedents, empirical referents and consequences of tolerance help healthcare professionals understand its complexities. Improved knowledge may ultimately influence patient outcomes through the construction of better monitoring systems. This concept analysis may also provide insights for policy change and give empirical direction for future research.

The purpose of this article is to review the literature and to highlight current practice regarding the management of the chronic pain patient presenting for surgery. ⋯ Successful management of the complex pain patient requires knowledge of the art and science of perioperative medicine.
