A&A practice

The Tritube is a narrow-bore cuffed tracheal tube (outer diameter 4.4 mm and inner diameter ~2.4 mm) that permits effective alveolar gas exchange using flow-controlled ventilation. Constant gas flow delivers physiological minute volumes, within preset pressure limits, and applies suction to the airway during expiration. ⋯ Cuff inflation protects the lower airway and produces a motionless operating field. We describe the structure of the device, discuss its benefits, and suggest how it should be used clinically.

The delivery of drugs from the manufacturer to the hospital is a complex process. Despite numerous safeguards, lapses may occur, creating the potential for patient harm. ⋯ No patients received the anesthetic. This report describes how such an error occurred, explains the differences between veterinary and human medications, and emphasizes the importance of vigilance in the drug supply chain to prevent patient harm.

We report a case of a patient who had a coronary angioplasty and received heparin, clopidogrel, and ticagrelor on the evening of bilateral total knee arthroplasties performed under combined spinal epidural anesthesia. After a multidisciplinary meeting, the epidural catheter was removed 5 days after the dose of clopidogrel. ⋯ Removing an epidural catheter in a patient on antiplatelet therapy must be done after a risk-benefit assessment, multidisciplinary collaboration, and stringent neurologic monitoring. The focus should be on prevention of a spinal hematoma, and rapid diagnosis and treatment to optimize the neurologic outcome.

Successful anesthetics occur when safe, effective perioperative care is coupled with patient satisfaction. We present the case of a 63-year-old woman with advanced Parkinson's disease who presented for a deep brain stimulation (DBS) device battery change under monitored anesthesia care (MAC). While MAC is commonly utilized for a DBS battery change, our patient reported previously experiencing intraoperative pain, anxiety, and the inability to communicate discomfort under MAC, leading to posttraumatic stress disorder. This case report highlights the importance of preoperative informed consent, discussion of patient expectations, and proactive planning for intraoperative communication strategies when MAC is the chosen method.
