A Retrospective Analysis of Patients Undergoing Telemedicine Evaluation in the PreAnesthesia Testing Clinic at H. Lee Moffitt Cancer Center.

BACKGROUND: Telemedicine for preanesthesia evaluation can decrease access disparities by minimizing commuting, time off work, and lifestyle disruptions from frequent medical visits. We report our experience with the first 120 patients undergoing telemedicine preanesthesia evaluation at Moffitt Cancer Center. METHODS: This is a retrospective analysis of 120 patients seen via telemedicine for preanesthesia evaluation compared with an in-person cohort meeting telemedicine criteria had it been available. Telemedicine was conducted from our clinic to a patient's remote location using video conferencing. Clinic criteria were revised to create a tier of eligible patients based on published guidelines and anesthesiologist consensus. RESULTS: Day-of-surgery cancellation rate was 1.67% in the telemedicine versus 0% in the in-person cohort. The two telemedicine group cancellations were unrelated to medical workup, and cancellation rate between the groups was not statistically significant (P = .49). Median round trip distance and time saved by the telemedicine group was 80 miles [range 4; 1180] and 121 minutes [range 16; 1034]. Using the federal mileage rate, the median cost savings was $46 [range $2.30; 678.50] per patient. Patients were similar in gender and race in both groups (P = .23 and .75, respectively), but the in-person cohort was older and had higher American Society of Anesthesiologists physical status classification (P = .0003). CONCLUSIONS: Telemedicine preanesthesia evaluation results in time, distance, and financial savings without increased day-of-surgery cancellations. This is useful in cancer patients who travel significant distances to specialty centers and have a high frequency of health care visits. American Society of Anesthesiologists Physical Status classification and age differences between cohorts indicate possible patient or provider selection bias. Randomized controlled trials will aid in further exploring this technology.

Over 12 Years Single Institutional Experience Performing Percutaneous Hepatic Perfusion for Unresectable Liver Metastases.

Patients with unresectable hepatic metastases, from uveal or ocular melanoma, are challenging to treat with an overall poor prognosis. Although over the past decade significant advances in systemic therapies have been made, metastatic disease to the liver, especially from uveal melanoma, continues to be a poor prognosis. Percutaneous hepatic perfusion (PHP) is a safe, viable treatment option for these patients. PHP utilizes high dose chemotherapy delivered directly to the liver while minimizing systemic exposure and can be repeated up to 6 times. Isolation of the hepatic vasculature with a double-balloon catheter allows for high concentration cytotoxic therapy to be administered with minimal systemic adverse effects. A detailed description of the multidisciplinary treatment protocol used at an institution with over 12 years of experience is discussed and recommendations are given. A dedicated team of a surgical or medical oncology, interventional radiology, anesthesiology and a perfusionist allows PHP to be repeatedly performed as a safe treatment strategy for unresectable hepatic metastases.

A novel approach to improving efficiency and cost saving in preoperative blood preparation.

BACKGROUND: Preoperative ordering of blood products has been an area of optimization due to considerable variability among physicians; overpreparation can lead to extra costs and underpreparation of blood can potentially compromise patient safety. STUDY DESIGN AND METHODS: We examined the potential cost savings of extending the storage interval of a presurgical type-and-screen sample from 7 to 14 days, thereby reducing the need for a new specimen on the day of surgery. RESULTS: Sensitivity analysis showed annual cost savings for our institution to be an estimated $38,770 ($22,420-$73,120). CONCLUSION: These results are even more robust when incorporating the additional potential savings from improved operating room efficiency.

Cardiac Remote Monitoring Devices and Technologies: A Review for the Perioperative Physician and Telemedicine Providers.

Cardiovascular complications are a major cause of morbidity and mortality after surgery, necessitating adequate and thorough preoperative risk stratification and screening. Several technological advances in cardiac remote monitoring have improved the assessment and diagnosis of cardiovascular disease in patients before and after surgery. These devices perform measurements of physiological function, including vital signs, and more advanced functions, such as electrocardiograms and heart sound recordings. Some of the currently available devices include Fitbit® (Google LLC, Mountain View, CA, USA), BodyGuardian® (Preventive Inc., Rochester, MN, USA), ZephyrTM Performance Systems (Zephyr Inc., Annapolis, MD, USA), Sensium® (The Surgical Company, Amersfoort, UT, The Netherlands), KardiaMobile® (AliveCor, Mountain View, CA, USA), Coala® Heart Monitor (Coala Life Inc., Uppsala, Sweden), Smartex® Wearable Wellness System (Smartex, Porto, LX, Portugal), Eko® CORE and DUO (Eko Health, Emeryville, CA, USA), and TytoCareTM (TytoCare Ltd., New York, USA). Early studies have applied these devices to asymptomatic individuals and those with known cardiovascular disease with good sensitivity and specificity for electrophysiologic diagnosis. These devices carry several technical and other limitations, somewhat restricting the generalization of their use to all patients. However, information gathered from these devices can further guide anesthetic technique, operative timing, and postoperative follow-up, among other variables. As telehealth becomes more prevalent and comprehensive, it is paramount for the perioperative physician to be familiar with the available cardiac remote monitoring technologies.

Diphenhydramine-Induced Torsade De Pointes With Pharmacological Cardioversion in a Patient With Methadone-Induced QT Prolongation.

The anesthetic management of patients with chronic pain requires a thorough understanding of the physiologic changes resulting from long-term exposure to opioids, as well as a firm comprehension of the pharmacodynamic and pharmacokinetic properties of these medications. We present the case of a 60-year-old woman on methadone therapy presenting for cervical laminectomy and fusion. After intraoperative dysrhythmias, she underwent pharmacological cardioversion from torsade de pointes. This occurred intraoperatively after receiving 25 mg of intravenous diphenhydramine to attenuate erythema thought to be secondary to antibiotic administration. The use of a routine antihistamine may present a torsadogenic reaction in the setting of methadone maintenance treatment.

How Sweet Is This? A Review and Evaluation of Preoperative Carbohydrate Loading in the Enhanced Recovery After Surgery Model.

Preoperative carbohydrate loading is a contemporary element of the enhanced recovery after surgery (ERAS) paradigm. In addition to intraoperative surgical and anesthetic modifications and postoperative care practices, preoperative optimization is essential to good postsurgical outcomes. What was long held as dogma, a period of prolonged fasting prior to the administration of anesthesia, was later re-examined and challenged. Along with the proposed physiologic effects of decreasing the surgical stress response and insulin resistance, preoperative carbohydrate loading was also demonstrated to improve patient satisfaction and well-being, without an increase in perioperative complications. The benefits are most strongly observed in abdominal and cardiac surgery patients, but there has also been data which support its use in other specialties and surgeries. Barriers to the adoption of perioperative carbohydrate loading are few, but importantly include overcoming the inertia to modify older and more restrictive fasting guidelines and achieving the multidisciplinary consensus necessary to implement such changes. Despite these challenges, and with an existing body of evidence supporting its benefits, preoperative carbohydrate loading presents a significant contribution to the ERAS programs.

Intraoperative Goal-Directed Anesthetic Management of the Patient with Severe Pulmonary Hypertension.

BACKGROUND It is very challenging for anesthesiologists to manage patients with pulmonary hypertension undergoing general anesthesia for elective or emergent surgeries. CASE REPORT We present a patient with severe pulmonary hypertension going through a major robotic thoracic surgery. CONCLUSIONS A goal-directed anesthesia management algorithm based on serial stroke volume (SV) values obtained from FloTrac (Edwards Lifesciences, LLC.) minimally invasive arterial pressure sensor was utilized in an attempt to reduce the anesthetic and surgical risk associated with severe pulmonary hypertension.

An adult patient with Klippel-Feil syndrome presenting for repeat operation: a cautionary tale of the GlideScope.

The introduction of video laryngoscopes has increased the success of intubating the difficult airway. However, failures have been reported in the literature that are associated with certain patient characteristics. Klippel-Feil Syndrome is a condition that typically presents with decreased cervical spine motion, a characteristic that has been associated with GlideScope failure. After an uneventful first anesthetic, a case of a near impossible-to-intubate occurred in a patient with Klippel-Feil Syndrome.
