The purpose of this paper is to examine physician barriers to adopting electronic medical records (EMRs) as well as anesthesiologists' experiences with the EMRs used by the acute pain management service at two tertiary care centres in Canada. ⋯ Use of EMRs will inevitably become the standard of care; however, many barriers persist to impede their implementation and adoption. These challenges to implementation can be facilitated by a corporate strategy for change that acknowledges the barriers and provides the resources for implementation. Adoption will facilitate benefits in communication, patient management, research, and improved patient safety.

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.

This narrative review aims to inform health care practitioners of the current literature surrounding the use of intrathecal (IT) and epidural analgesia in cancer patients with refractory pain at end of life. Topics discussed and reviewed include: patient selection, treatment planning, procedure, equipment, medications, complications, policies and procedures, as well as directions for future research. ⋯ Neuraxial drug delivery gives clinicians more options to manage refractory pain at end of life and should be offered to patients with intractable cancer pain. Teams should be interprofessional with clear delineation of roles and responsibilities. They should discuss advanced discharge planning with the patient prior to implantation as well as provide on-call support.

Hypoxic pulmonary vasoconstriction (HPV) is a fundamental physiological process whereby ventilation/perfusion matching is optimized through the constriction of the pulmonary circulation supplying poorly ventilated lung units. In their 1981 paper in the Journal, Noble, Kay, and Fisher used a series of animal experiments to show that alveolar carbon dioxide (CO2) plays a critical role in the regulation of hypoxic pulmonary vasoconstriction. At physiological concentrations, CO2 potentiates the HPV response, and the absence of alveolar CO2 blunts HPV. The enhancement of HPV by CO2 resulted in reduced perfusion of specific hypoxic lung regions, thereby improving systemic oxygenation in lung-ventilated dogs.

This study was undertaken to determine the contribution of postoperative pain to the known changes that occur to respiratory function in the postoperative period. The authors studied changes in functional residual capacity (FRC) and vital capacity (VC) either in the postanesthesia care unit or on postoperative day one in eight relatively healthy adult patients having upper abdominal surgery. ⋯ Epidural analgesia to a T4 sensory level resulted in a partial and statistically significant restoration of VC (from 37-55% of preoperative values) and a partial but statistically insignificant restoration of FRC (from 78-84% of preoperative values). The authors suggest that postoperative epidural analgesia may be able to decrease respiratory complications.
