Randomized Controlled Trial Comparative StudyProspective, Randomized Comparison of the i-gel and the Self-Pressurized air-Q Intubating Laryngeal Airway in Elderly Anesthetized Patients.
Age-related changes in upper airway anatomy may affect the overall performance of supraglottic airways significantly. The clinical performance of the i-gel and the self-pressurized air-Q intubating laryngeal airways with noninflatable cuffs for elderly populations remains unknown, unlike in children. Thus, we performed a prospective, randomized comparison of these 2 supraglottic airways in elderly patients undergoing general anesthesia. ⋯ The i-gel provided better sealing function than the self-pressurized air-Q supraglottic airway according to the high oropharyngeal leak pressures in elderly patients during general anesthesia. The self-pressurized air-Q supraglottic airway had improved fiberoptic views in elderly patients during general anesthesia.

ReviewTo Infinity and Beyond: The Past, Present, and Future of Tele-Anesthesia.
Because the scope of anesthesia practice continues to expand, especially within the perioperative domain, our specialty must continually examine technological services that allow us to provide care in innovative ways. Telemedicine has facilitated the remote provision of medical services across many different specialties, but it remains somewhat unclear whether the use of telemedicine would fit within the practice of anesthesiology on a consistent basis. There have been several reports on the successful use of telemedicine within the preoperative and intraoperative realm. ⋯ This article seeks to review comprehensively the available literature related to the use of telemedicine within the preoperative, intraoperative, and postoperative phases of anesthetic care as well as analyze the major hurdles often encountered when implementing a teleconsultation service. Security of connection, data storage and encryption, federal and state medical licensure compliance, as well as overall cost/savings analysis are a few of the issues that warrant further exploration and research. As telemedicine programs develop within the perioperative arena, it is imperative for institutions to share knowledge, successes, and pitfalls to improve the delivery of care in today's technology-driven medical landscape.

Hip fracture is a challenging geriatric problem for the health care professionals, especially in patients with multiple comorbidities. In patients with inoperable hip fracture secondary to severe comorbid conditions, the pain can lead to significant challenges in nursing care. With the current understanding of the innervation of hip joint, we are now able to perform selective chemical denervation of the articular branches of femoral and obturator nerves to manage the pain associated with inoperable hip fracture. ⋯ We concluded that this chemical hip denervation could be a safe and effective measure to handle the pain-related and rehabilitation-related challenges as a result of inoperable hip fracture.

Estimating the Impact of Carbon Dioxide Absorbent Performance Differences on Absorbent Cost During Low-Flow Anesthesia.
Reducing fresh gas flow when using a circle anesthesia circuit is the most effective strategy for reducing both inhaled anesthetic vapor cost and waste. As fresh gas flow is reduced, the amount of exhaled gas rebreathed increases, but the utilization of carbon dioxide absorbent increases as well. Reducing fresh gas flow may not make economic sense if the increased cost of absorbent utilization exceeds the reduced cost of anesthetic vapor. The primary objective of this study was to determine the minimum fresh gas flow at which absorbent costs do not exceed vapor savings. Another objective is to provide a qualitative insight into the factors that influence absorbent performance as fresh gas flow is reduced. ⋯ The relative costs of anesthetic vapor and carbon dioxide absorbent as fresh gas flow is reduced are dependent on choice of anesthetic vapor and performance of the carbon dioxide absorbent. Absorbent performance is determined by the product selected and strategy for replacement. Clinicians can maximize the performance of absorbents by replacing them based on the appearance of inspired carbon dioxide rather than the indicator. Even though absorbent costs exceed vapor savings as fresh gas flow is reduced, isoflurane is still the lowest cost choice for the environmentally sound practice of closed-circuit anesthesia.
