Study Objective: The aim of this study is to see if there are any clinical differences between using 35 F DLT for all patients versus using patient height regardless of gender to estimate appropriate DLT size. Design: Prospective randomized study. Setting: University Hospital. Patients: 50 patients age ≤18 years, undergoing lung or esophageal surgery requiring OLV. Interventions: Patients randomized to two groups (group-35F, group –DLT based on height). Measurements and Main Results: Data collected include demographics, ASA status, airway assessment, number of intubation attempts, Cormack-Lehane grade, number of times DLT repositioned, incidence of sore throat, oxygen saturation at induction and oxygen saturation at 5 minutes and 10 minutes after OLV. There was no statistically significant difference in demographics, ASA classification, Mallampati score, number of intubation attempts, Cormack-Lehane grade, number of times DLT was repositioned, and incidence of sore throat. In height based DLT group the odds were higher for the incidence of sore throat in 37-41 F group. Oxygen saturation at induction, 5 minutes and 10 minutes after OLV are not statistically significant between the two groups. Conclusion: Our findings suggest that the majority of patients receive unnecessarily large DLTs for thoracic surgery, which not only makes intubation inherently more difficult but also increases their risk of postoperative sore throat.

Opioid sparing anesthesia and enhanced recovery after surgery protocols are not innovative ideas. However, the utilization of pancreaticoduodenectomy is limited. With the rise in awareness of the opioid epidemic in the United States, we have created a multimodal approach to anesthesia and postoperative care to limit adverse effects of opioids and curb the use of opioids postoperatively. We conducted a retrospective cohort study performed by chart review of an opioid-sparing anesthetic and enhanced recovery after surgery (ERAS) protocol initiated jointly by the anesthesiology departments and transplant surgery for pancreaticoduodenectomy from January 2017 to October 2019. Demographic data was found to be comparable between the control and protocol groups. Hospital length of stay, ICU length of stay, and opioid requirements significantly decreased in the protocol group. Hospital length of stay decreased from 8.92 to 5.72 days, ICU days decreased from 1.52 to 0.42 days, and narcotics for the first five hospital days were significantly decreased from 130.13 to 71.2 morphine milligram equivalents. Proper postoperative pain management can improve patient satisfaction and decrease complication rates. Pancreaticoduodenectomy is a complicated procedure with relatively limited data regarding enhanced recovery after surgery protocols. Likewise, there is limited data regarding opioid-sparing anesthesia techniques. Our protocol produced promising hospital length of stay and reduced opioid administration during the first five hospital days without increasing 30-day readmission rates.

Amplatzer Atrial Septal Occluder device has been routinely and successfully used as a percutaneous alternative to cardiac surgery for closure of atrial septal defects. It has shown to the safe with a low complication profile. Complications that most commonly occur with atrial septal defect (ASD) closure devices include malposition or embolization, residual shunt, atrial arrhythmias, thrombosis over the vena cava or atrium, erosion and perforation of the heart, and infective endocarditis. The most common complications associated with an ASD occluder device appear to be embolization and malposition with embolization usually occurring in the main pulmonary artery. We present a case in which the ASO device, Amplatzer^TM (Abbott, USA), embolized into the left ventricle.

Objectives: Demonstrate the feasibility and effectiveness of using the AirSim^® Bronchi airway simulator to teach anesthesia residents how to successfully troubleshoot and manage malpositioned double-lumen endotracheal tubes used for single-lung ventilation. Design: Prospective observational study. Setting: Simulation lab in a university-based anesthesiology residency training program. Participants: CA1 (PGY2) anesthesiology residents. Interventions: Each resident was initially tasked with troubleshooting a malpositioned double-lumen tube (DLT) on an AirSim^® Bronchi (Trucorp, Craigavon, UK) airway simulator in one of the three positions and was timed on their performance. This first simulation was followed by completion of a survey that assessed the resident’s level of confidence in repositioning a malpositioned DLT. Following the initial simulation, a didactic presentation was given to the residents on the management of malpositioned DLTs using a protocol, followed by a practice session. Two months later, each resident repeated the simulation exercise. A follow-up survey was conducted after each simulation, assessing the quality of the curriculum and subsequent level of confidence in performing the same tasks using a five-point Likert scale. Measurements and Main Results: Ten residents at the University of Mississippi Medical Center completed the simulation exercises and curriculum. The average time it took to troubleshoot the malpositioned DLT during the first simulation was 139 s, with only 30% of the residents correctly identifying the specific malposition and 40% correctly repositioning the DLT after initial malposition. The repeat simulation after two months showed significant improvement in efficiency, with the average time to complete the task decreasing from 139 s to 56 s. During the second simulation exercise, all 10 residents were able to correctly identify the DLT malposition and correctly reposition the DLT to the correct position. Additionally, residents’ confidence levels in managing a malpositioned DLT improved significantly. Initially, 70% of the residents reported a lack of confidence in identifying and correcting a malpositioned DLT, but after the didactic curriculum and simulation training, 100% of the residents reported confidence in completing the task. Conclusions: The AirSim^® Bronchi (Trucorp, Craigavon, UK) simulator can be used to effectively teach and evaluate residents on correctly identifying and repositioning a malpositioned DLT. The residents’ performance and level of confidence were evaluated before and after the simulation curriculum. The results reveal that simulation-based training is an effective educational tool for improving clinical performance and confidence in identifying and appropriately managing a malpositioned DLT.

Key Clinical Message: It is important to be aware of complications associated with axillary artery cannulation, especially the more common ones that can compromise limb integrity. Pulse oximeter and arterial line placed on the right upper extremity can aid in perfusion of the right arm during right axillary artery cannulation.

In patients presenting to the operating room with a saddle pulmonary embolism for noncardiac surgery, it is best to take a multidisciplinary approach and involve the cardiac and vascular surgeons.
