Introducing information literacy into anesthesia curricula.

PURPOSE: This review examines the topic of information literacy (IL) and its importance as a component of competency-based education in the health professions, and shares the process and outcome of a collaborative effort between The University of Manitoba Department of Anesthesia and Health Sciences Libraries to create, to introduce and integrate IL training into a new anesthesia curriculum. PRINCIPLE FINDINGS: Nine IL modules were developed according to standards set by the Association of College and Research Libraries (ACRL) and aligned with the Royal College of Physicians and Surgeons CanMEDS competencies. Taken collectively, they explore modern tools used to approach the medical literature in an organized, efficient manner, and to locate, evaluate and use information effectively to accomplish a specific purpose. Each module forms the basis of one IL session that combines self-study and group projects with librarian-led, computer-based training, designed to build competency in information need awareness, retrieval skills and resource appraisal. Facility with the concepts taught was evaluated though examples relevant to the anesthesia practice environment. The entire collection is available at http://wiki.lib.umanitoba.ca/tiki-index.php?page=Anesthesia+Clinical+Assistants+Programme. While the original impetus for this project was to prepare Anesthesia Clinical Assistants for self-directed, life-long, active learning, what emerged was a curriculum in IL germane to medical specialties and flexible enough to be used by healthcare professions generally. CONCLUSION: An IL program, directly relevant to current expectations of competent practice, education and lifelong learning, has been created and is discussed within the larger context of curriculum-integrated IL for the health professions.

The effect of epidural needle type on postdural puncture headache: a randomized trial.

PURPOSE: A prospective, randomized trial in labouring parturients was undertaken to assess whether the 18G Special Sprotte epidural needle is associated with a lower incidence of accidental dural puncture (ADP) in comparison with the 17G Tuohy needle. A secondary purpose was to determine if the incidence of postdural puncture headache (PDPH ) differed between groups when ADP occurred. METHODS: Following Institutional Review Board approval 1,077 parturients requesting epidural analgesia at three tertiary obstetrical units were randomized to epidural catheter insertion with a 17G Tuohy or 18G Special Sprotte needle. Patients were followed for seven days by a blinded assessor to determine the occurrence of PDPH using standardized criteria. If postural headache or neck ache presented, an ADP was diagnosed even if cerebrospinal fluid (CSF) was not observed at insertion. This subgroup was followed daily to assess headache characteristics and response to blood patch. RESULTS: Six Tuohy group patients, and two patients in the Sprotte group were excluded. One of the six excluded in the Tuohy group had an ADP. Twenty-eight ADPs occurred, nine unrecognized by CSF visualization (1.8% Tuohy, 3.4% Sprotte, P = 0.12). The incidence of unrecognized ADPs was higher in the Sprotte group (40% Sprotte vs 20% Tuohy, P < 0.05). If ADP occurred, the incidence of PDPH was lower in the Sprotte group (100% Tuohy vs 55% Sprotte, P = 0.025). The ease of use, and user satisfaction were higher in the Tuohy group (84 +/- 17.3% Tuohy vs 68.2 +/- 25.3% Sprotte, P < 0.001). CONCLUSION: The incidence of ADP was not reduced with the Special Sprotte epidural needle in comparison with the Tuohy needle, but PDPH after ADP occurred less frequently in the Sprotte group.

Effects on the fetus and newborn of maternal analgesia and anesthesia: a review.

PURPOSE: To review the effects of maternal anesthesia and analgesia on the fetus and newborn. METHODS: An on-line computerized search of Medline, Embase, and the Cochrane Collaboration via PubMed was conducted. English language articles were selected. The bibliographies of relevant articles and additional material from other published sources were retrieved and reviewed. PRINCIPAL FINDINGS: No one test clearly separates the effects on the fetus/newborn, if any, of maternally administered medication during labour and delivery, or during surgery for non-obstetric indications. Supposition in this regard is limited in part by methodology previously used to study the transplacental passage of various drugs. This work needs to be repeated using a human model. Routine maternal supplemental oxygen administration is being questioned in light of research showing that free radical generation and oxidative stress are implicated as the underlying mechanisms in several neonatal conditions. Maternal hypotension is associated with neonatal acidemia and base excess correlates with neonatal outcome. Common postpartum analgesics transfer minimally into breast milk. Maternal or fetal surgery conducted during pregnancy necessitates modification of both anesthetic and surgical approaches. The key to resuscitation of the fetus is resuscitation of the mother: intra-uterine maneuvers, including perimortem Cesarean section, aim to reverse treatable causes of fetal asphyxia, restore fetal oxygenation, and correct fetal acidosis. CONCLUSIONS: The well-being of the infant is a major criterion for evaluating the anesthetic management of pregnant women. Many tools exist to assist with this determination for the fetus, whereas few are available to evaluate the newborn.
