Optimal length of the pre-inserted tracheal tube for excellent view in nasal fiberoptic intubation.
Inexperienced physicians frequently have difficulty performing nasal fiberoptic intubation. A pre-inserted tracheal tube of the appropriate length allows an excellent view of the laryngeal opening. The purpose of this study was to determine the ideal length of a pre-inserted tracheal tube for nasal fiberoptic intubation and to investigate if it could be predicted from easily measureable patient parameters. ⋯ The optimal length of pre-inserted tracheal tube for nasal fiberoptic intubation can be predicted using a newly developed formula with three patient parameters, namely, height, the NM distance, and weight. Application of this equation in the clinical setting should facilitate nasal fiberoptic intubation.

ReviewIschaemic and inflammatory injury in renal graft from brain death donation: an update review.
Renal transplantation remains an important therapy in treating renal failure and can be considered to be a curative treatment. The demand for renal grafts outstrips supply available each year, making it increasingly important to look at improving the treatment of both renal grafts and recipients, and thereby improving patient outcomes and increasing the pool of potential donor grafts. Important to this, however, is knowledge of the underlying mechanisms leading to damage to the graft and rejection from the recipient. ⋯ This makes the time period involving both explantation and storage an important therapeutic window for improving outcomes. Other windows explored include treatment of IRI and improvement in immunosuppressive therapy. The multiple windows of potential therapeutic input have spawned a large body of work exploring both the underlying mechanisms and also how to exploit these mechanisms to improve overall outcomes and to allow for more marginal organs to be used.

In this review, we describe the current consensus surrounding general anesthetic management for cesarean section. For induction of anesthesia, rapid-sequence induction using thiopental and suxamethonium has been the recommended standard for a long time. In recent years, induction of anesthesia using propofol, rocuronium, and remifentanil have been gaining popularity. ⋯ After the delivery of a fetus, switching from volatile anesthetics to intravenous anesthetics has been recommended to avoid uterine atony. At the same time, intraoperative awareness should be avoided. The rate of persistent wound pain is higher when only general anesthesia was used during cesarean section than with regional anesthesia, and thus it is necessary to provide a sufficient postoperative analgesia using multimodal analgesia, including intravenous patient-controlled analgesia (IV-PCA), transversus abdominis plane (TAP) block, non-steroidal inflammatory drugs, and acetaminophen.

Case ReportsManagement of pudendal neuralgia using ultrasound-guided pulsed radiofrequency: a report of two cases and discussion of pudendal nerve block techniques.
Pudendal neuralgia is characterized by chronic pain or discomfort in the area innervated by the pudendal nerve, with no obvious cause. A successful pudendal nerve block is crucial for the diagnosis of pudendal neuralgia. ⋯ This report describes two cases of pudendal neuralgia that were successfully managed using ultrasound-guided pulsed radiofrequency and presents a literature review of pudendal nerve block techniques. However, in the management of chronic neuropathic pain, physicians should keep in mind that the placebo effect related to invasive approaches must not be neglected.

ReviewReview of crisis resource management (CRM) principles in the setting of intraoperative malignant hyperthermia.
The practice of medicine is characterized by routine and typical cases whose management usually goes according to plan. However, the occasional case does arise which involves rare catastrophic emergencies, such as intraoperative malignant hyperthermia (MH), which require a comprehensive, coordinated, and resource-intensive treatment plan. ⋯ However, physicians can become expert in the global process of managing emergencies by using the principles of crisis resource management (CRM). In this article, we review the key concepts of CRM, using a real life example of a team who utilized CRM principles to successfully manage an intraoperative MH crisis, despite there being no one on the team who had ever previously encountered a true MH crisis.
