Perioperative Ulnar Neuropathy: A Contemporary Estimate of Incidence and Risk Factors.

BACKGROUND: Retrospective and prospective studies 2 decades ago from the authors' institution reported the incidence of perioperative ulnar neuropathy persisting for at least several months in a noncardiac adult surgical population to be between 30 and 40 per 100,000 cases. The aim of this project was to assess the incidence and explore risk factors for perioperative ulnar neuropathy in a recent cohort of patients from the same institution using a similar definition for ulnar neuropathy. METHODS: We performed a retrospective incidence and case-control study of all adults (≥18 years) undergoing noncardiac procedures with anesthesia services between 2011 and 2015. Each incident case of persistent ulnar neuropathy within 6 months of surgery was matched by age, sex, procedure date, and procedure type to 5 surgical patient controls. For the case-control study, separate conditional logistic regression analyses were performed to assess specific risk factors including the patient's body position and arm position, as well as body mass index (BMI), surgical duration, and selected patient comorbidities. RESULTS: Persistent ulnar neuropathy of at least 2 months duration was found in 22 of 324,124 anesthetics for patients who underwent these procedures during the study period for an incidence rate of 6.8 (95% confidence interval [CI], 4.3-10.3) per 100,000 anesthetics. The incidence of ulnar neuropathy was higher in men compared to women (10.7 vs 3.0 per 100,000; P = .016). From the matched case-control study, the odds of ulnar neuropathy increased with higher BMI (odds ratio [OR] = 1.67 [1.16-2.42] per 5 kg/m2 increase in BMI; P = .006), history of cancer (OR = 6.46 [1.64-25.49]; P = .008), longer procedures (OR = 1.53 [1.18-1.99] per hour; P = .001), and when 1 or both arms were tucked during surgery (OR = 6.16 [1.85-20.59]; P = .003). CONCLUSIONS: The incidence of persistent perioperative ulnar neuropathy observed in this study was lower than the incidence reported 2 decades ago from the same institution and using a similar definition for ulnar neuropathy. Several of the previously reported risk factors continue to be associated with the development of persistent perioperative ulnar neuropathy, providing ongoing targets for practice changes that might further decrease the incidence of this problem.

The effects of shoulder arthroscopy on ultrasound image quality of the interscalene brachial plexus: a pre-procedure vs post-procedure comparative study.

BACKGROUND: Fluid extravasation from the shoulder compartment and subsequent absorption into adjacent soft tissue is a well-documented phenomenon in arthroscopic shoulder surgery. We aimed to determine if a qualitative difference in ultrasound imaging of the interscalene brachial plexus exists in relation to the timing of performing an interscalene nerve block (preoperative or postoperative). METHODS: This single-center, prospective observational study compared pre- and postoperative interscalene brachial plexus ultrasound images of 29 patients undergoing shoulder arthroscopy using a pretest-posttest methodology where individual patients served as their own controls. Three fellowship-trained regional anesthesiologists evaluated image quality and confidence in performing a block for each ultrasound scan using a five-point Likert scale. The association of image quality with age, gender, BMI, duration of surgery, obstructive sleep apnea, and volume of arthroscopic irrigation fluid were analyzed as secondary outcomes. RESULTS: Aggregate preoperative mean scores in quality of ultrasound visualization were higher than postoperative scores (preoperative 4.5 vs postoperative 3.8; p < .001), as was confidence in performing blockade based upon the imaging (preoperative 4.8 vs postoperative 4.2; p < .001). Larger BMI negatively affected visualization of the brachial plexus in the preoperative period (p < 0.05 for both weight categories). Patients with intermediate-high risk or confirmed obstructive sleep apnea had lower aggregate postoperative mean scores compared to the low-risk group for both ultrasound visualization (3.4 vs 4.0; p < .05) and confidence in block performance (3.8 vs 4.4; p < .05). CONCLUSION: Due to the potential reduction of ultrasound visualization of the interscalene brachial plexus after shoulder arthroscopy, we advocate for a preoperative interscalene nerve block when feasible.

Burnout Among Women Physicians: a Call to Action.

PURPOSE OF REVIEW: The purposes of this discussion are to describe what is known about burnout among women physicians and identify contributing factors, categories of impact, and methods for mitigating the phenomenon. The authors conclude with current gaps in research. RECENT FINDINGS: Although there are a lack of investigations analyzing and reporting physician burnout data by gender, there is evidence to suggest that women physicians experience stress and burnout differently than their men counterparts. Women physicians are more likely to face gender discrimination, gender biases, deferred personal life decisions, and barriers to professional advancement, all of which may contribute to burnout. Interventions specific to preventing physician burnout in women should include (1) addressing barriers to career satisfaction, work life integration, and mental health; (2) identification and reduction of gender and maternal bias; (3) mentorship and sponsorship opportunities; (4) family leave, lactation, and child care policies and support. In addition, gaps in research must be addressed in an effort to inform best practices for measuring and addressing burnout among women physicians.

Opioid-Sparing Pain Management in Upper Extremity Surgery: Part 1: Role of the Surgeon and Anesthesiologist.

A multimodal pain management strategy combines complementary medications and techniques, targeting unique pathways, to improve overall analgesic effect and reduce opioid requirements. In this 2-part review, we examine the literature identifying nonopioid analgesic modalities and their targets in the pain pathway as well as anesthetic techniques found to be opioid-sparing in the practice of upper extremity surgery. First, we focus on operative anesthesia and analgesia and areas for future research specific to upper extremity surgery. In part 2, we discuss the nonopioid options available after surgery.

How does training in anesthesia residency shape residents' approaches to patient care handoffs? A single-center qualitative interview study.

BACKGROUND: Handoffs are a complex procedure whose success relies on mutual discussion rather than simple information transfer. Particularly among trainees, handoffs present major opportunities for medical error. Previous research has explored best practices and pitfalls in general handoff education but has not discussed barriers specific to anesthesiology residents. This study characterizes the experiences of residents in anesthesiology as they learn handoff technique in order to inform strategies for teaching this important component of perioperative care. METHODS: In 2016, we conducted a semi-structured interview study of 30 anesthesia residents across all three postgraduate years at a major academic hospital. Interviews were coded by two coders using a grounded theory approach and an iterative process designed to enhance reliability and validity. RESULTS: Residents cited lack of consistency as a major impediment to proper handoff education. They found the impact of lectures and written materials to be limited. The level of guidance and direction they received from one-to-one attendings was described as highly variable. Residents' comfort in executing handoffs was heavily dependent on location and situation. They felt that coordination among the parties involved in the handoff was difficult to achieve, causing confusion about the importance of handoffs as well as proper protocol. Finally, residents offered opinions on when handoff education should occur during the residency and had several recommendations for its improving, including standardization of key handoff topics. CONCLUSIONS: In a single center study of anesthesiology resident handoff education, residents exhibited confusion related to a perceived disconnect between the stated importance of effective handoffs and a lack of consensus on proper handoff technique. Standardization of curriculum and framing expectations has the potential to enhance resident handoff training in academic anesthesia departments.

Improving the Mental Health of Surgical Teams Through Operating Room Design.

OBJECTIVE: In this study, we aim to develop and propose an evaluation method for analyzing the design of operating rooms (ORs) from the perspective of surgical teams' reported experiences and stress levels. BACKGROUND: Stress and burnout of surgical team members can lead to diminished performance and medical errors, which endangers the safety of both the patients and team members. The design and layout of the OR play a critical role in managing such stress. METHODS: To understand surgical teams' spatial needs related to their experiences and stress, we administered a survey and in-depth focus group discussions to three surgical teams from the same organization. The identified spatial needs were translated into functional scenarios and spatial metrics, essentially viewing the OR through the perspective of users. RESULTS: Our analysis revealed four integral sections-patient flow, room organization, access to facilities/medical equipment/support staff/team members, and staff well-being-identified as critical design factors associated with the experiences and stress levels of the surgical teams in the ORs. CONCLUSIONS: We expect this method to serve as a tool for evaluating the effect of the design of OR layouts on stress, thereby supporting the well-being and resiliency of surgical teams.

Respiratory Failure After Supraclavicular Nerve Block in a Patient With a Contralateral Brachial Plexus Injury: A Case Report.

CASE: A patient with prior left-sided brachial plexus trauma and associated left phrenic nerve paralysis subsequently developed transient respiratory failure after a contralateral supraclavicular nerve block. Her known left phrenic nerve palsy secondary to her index brachial plexus injury was rediscovered during the workup of her acute respiratory distress, which resulted in an emergent intensive care unit admission. CONCLUSION: The paralysis of her right phrenic nerve at the time of left-sided regional anesthesia was identified as the etiology of near-complete bilateral diaphragmatic paralysis and respiratory failure.

Implementation of a Second Victim Peer Support Program in a Large Anesthesia Department.

The second victim phenomenon occurs when healthcare providers experience emotional or physical distress as a result of traumatic clinical events. Few hospitals have formalized peer support programs for second victims to navigate the postevent experience and offload associated emotional labor. This article describes the implementation of a second victim peer support program in a large academic anesthesiology practice, with the goal of augmenting emotional support for anesthesia providers. Program activations were tracked in a shared mailbox. Following peer support, second victims completed an evaluation assessing support received; trained peer supporters completed 2 evaluations assessing their comfort level and peer support encounters. From July 2018 to June 2020, ninety-one program activations (179 affected individuals) were made. A total of 130 peer support encounters were documented. Trained peer supporters were able to provide helpful support to affected colleagues nearly all (98.8%) of the time. Nearly 97% of second victims (25 of 31 evaluation respondents) reported the support as extremely or very beneficial, and 96.8% would recommend the program to colleagues. A second victim peer support program was successfully deployed in a large anesthesia department. This program was effective at a departmental level, fostering providers' well-being.

Partnering with Palliative Care: A Case Report of Severe Pain in Critical Limb Ischemia Treated Successfully with a Continuous Popliteal Nerve Catheter.

BACKGROUND: Critical limb ischemia (CLI) is limb pain occurring at rest or impending limb loss as a result of lack of blood flow to the affected extremity. CLI pain is challenging to control despite multimodal pharmacologic analgesia and surgical intervention. We described the successful use of a continuous local anesthetic infusion via a popliteal nerve catheter to control severe refractory ischemic lower limb pain in a patient who failed surgical intervention and performed a brief narrative literature review on regional anesthesia for ischemic pain. Case Presentation. A 74-year-old female with acute myelogenous leukemia presented with CLI after experiencing left popliteal artery occlusion. Palliative medicine service was consulted for pain management in the setting of escalating narcotic dose requirements. She experienced a complicated hospital course with several failed attempts at surgical revascularization due to arterial rethrombosis. In accordance with the patient's goals of care, a continuous popliteal nerve catheter was placed, despite the high risk nature of an intervention in an immunocompromised patient with thrombocytopenia (platelet count of 30,000 platelets/microliter) and ongoing therapeutic anticoagulation. The patient experienced immediate relief while transitioning to comfort care. CONCLUSION: This is the first report of successful analgesia for CLI via a continuous popliteal catheter in a patient with rethrombosis and failed surgical revascularization. Based on our collaborative experience, we recommend the development of partnerships between the acute pain service and palliative care service to facilitate the early evaluation and decision to utilize regional anesthesia for treatment of CLI.
