Almost as critical as an operation itself is the preparation of the patient. Although this often includes psychosocial concerns such as expectations of recovery, inpatient stay, and other patient-centered issues, the discussion prior to surgery should not be limited to these factors. A medical assessment of the patient’s fitness and physiologic preparedness for the planned procedure must be performed by the surgeon and the resultant findings and plan reviewed with the patient. Although vascular disease affects multiple organ systems requiring a thorough general preoperative patient assessment, the focus of preoperative risk reduction strategies center on cardiac outcomes. Therefore, this review focuses on cardiac-related interventions with added coverage of preoperative strategies regarding diabetes, pulmonary and renal risk assessment, and infection reduction. Lastly, the perioperative management of anticoagulation/antiplatelet medications and cerebrovascular disease are discussed Techniques and treatments to optimize patients for surgery are integrated into the respective sections, allowing for a primer to guide this critical phase in a patient’s journey through surgery. Tables outline the Revised Cardiac Risk Index, assessment of functional capacity from patient self-reported activities, optimal delay in elective surgery after percutaneous coronary revascularization according to the 2014 American College of Cardiology/American Heart Association clinical practice guidelines, Respiratory Failure Risk Index, Szilagyi classification of vascular surgical site infection, and recommendations regarding perioperative management of anticoagulants and antiplatelet agents. A suggested algorithm for preoperative cardiac workup and the Cockcroff-Gault equation are provided. This review contains 2 figures, 6 tables, and 115 references.

Background: Starting from early to mid 2000s a growing body of literature has been produced on the potential role of statins in reducing perioperative cardiac events in patients undergoing non-cardiac surgery. However, evidence remains inconsistent and little is known regarding the use of perioperative statins in clinical practice. Objectives: To examine pattern of statin initiation among patients undergoing non-cardiac elective surgery in the US. Methods: Using data from a large US healthcare insurer, we identified patients ≥18 years who underwent moderate- to high-risk non-cardiac elective surgery and initiated statins within 30-days before surgery. We assessed trends of statin initiation over time and predictors of initiation. To ensure statin initiation was precipitated by non-cardiac surgery vs. alternative indications, we also assessed the effect of temporal proximity to surgery on initiation in a matched analysis. Results: Of 460,154 patients undergoing surgery between 2003-2012, 5,628 (1.2%) initiated a statin before surgery. Initiation rate increased from 0.8% in 2003 to 1.5% in 2012 (p = .0004). The increase was more pronounced among patients with revised cardiac risk index (RCRI) score ≥2 and patients undergoing vascular surgery, with initiation rates equal to 7.2% and 14.9% respectively by the end of 2012. Proximity to surgery was predictive of statin initiation (p < .0001). Significant predictors of initiation were older age, male sex, revised cardiac risk index (RCRI) score ≥1, vascular or orthopedic surgery. At the most recent estimate, patients undergoing vascular surgery and with a RCRI score ≥2 had initiation rates equal to 19.9%. Conclusions: The rate of statin initiation progressively increased from 2003 to 2012, particularly among patients with higher RCRI score and undergoing major vascular surgery. Research is needed to further define the risks and benefits of initiation of statins prior to surgery.

Physiologic changes of pregnancy and cystic fibrosis pathology provide a unique set of circumstances. Pulmonary disease accounts for over 90% of the morbidity and mortality of patients with cystic fibrosis. These abnormalities create anesthetic challenges due to multiple organ systems being affected including the respiratory, gastrointestinal, cardiovascular, and genitourinary tracts, where patients present with chronic respiratory failure, pancreatic insufficiency, poor nutrition, and cardiac manifestations. We present the perianesthetic management of a parturient with cystic fibrosis who successfully underwent preterm cesarean delivery under neuraxial anesthesia with preemptive bilateral femoral venous sheaths placed for potential extracorporeal membrane oxygenation (ECMO) initiation.

Background and Aims: Advanced age increases risk of perioperative cardiovascular complications and might therefore pose reluctance to subject elderly patients to surgery. We examined the impact of high age on perioperative major adverse cardiovascular events (MACE) and mortality in a nationwide cohort of patients undergoing elective surgery. Methods: All Danish patients aged ≥20 years undergoing non-cardiac, elective surgery in 2005-2011 were identified from nationwide administrative registers. Risks of 30-day MACE (non-fatal ischemic stroke, non-fatal myocardial infarction, or cardiovascular death) and all-cause mortality were analysed by multivariable logistic regression models (adjusted for major comorbidities, revised cardiac risk index, cardiovascular pharmacotherapy, body mass index, and surgery type). Results: A total of 386,818 procedures were included; mean age 56 years (min-max 20-104), 44% women. In total 1,297 (0.34%) had perioperative MACE and 1,449 (0.37%) died. Odds ratios increased with higher age for both MACE and mortality (Figure). Each 10-year higher age was associated with odds ratio 1.87 (1.78-1.98) for MACE, and 1.86 (1.77-1.95) for mortality. In total of 19,849 procedures were performed in patients 81-90 years of age, and 1,662 on patients ≥90 years. The crude MACE and mortality rates were 331 (1.7%) and 388 (2.0%) among 81-90 years old, and 50 (3.0%) and 67 (4.6%) for those aged ≥90 years. Conclusion: The risk of mortality and major adverse cardiovascular events within 30 days after surgery increased linearly with advanced age. However, despite advanced age the absolute event rates were relatively modest and below 5% even for people aged ≥90 years.

Few patient complaints offer such a large range of acuity and differential diagnoses as the complaint of leg pain. This is in part due to the multiple organ systems at play, including cardiac, pulmonary, musculoskeletal, neurologic, vascular, and dermatologic. The surgeon is frequently presented with the challenge of identifying and managing these complaints in a variety of settings. Management involves a spectrum from conservative care to surgical intervention where appropriate. The wide array of symptoms, signs, and often contradictory test results can be confusing and frustrating to patients and physicians alike, leading to delays and errors in diagnosis and ineffective management. This review offers a sequential and ordered approach to the evaluation of leg pain. Tables highlight atherosclerotic risk factors, vascular causes of lower extremity pain, the classification of acute limb ischemia, the ankle-brachial index and corresponding peripheral arterial disease, and the revised cardiac risk score for preoperative risk. Figures show bilateral lower extremity ischemia, chronic ischemic changes to the foot, classic dry gangrene, wet gangrene, acute limb ischemia, Charcot foot, segmental waveform and pulse volume recording analysis of the bilateral lower extremities, and angiographic evaluation of patients with aortoiliac and tibial disease. This review contains 10 figures, 5 tables, and 55 references.

Background Myocardial infarction is an important complication after noncardiac surgery. Therefore, perioperative troponin surveillance is recommended for patients at risk. The aim of this study was to identify patients at high risk of perioperative myocardial infarction (POMI), in order to aid appropriate selection and to omit redundant laboratory measurements in patients at low risk. Methods and Results This observational cohort study included patients ≥60 years of age who underwent intermediate to high risk noncardiac surgery. Routine postoperative troponin I monitoring was performed. The primary outcome was POMI. Classification and regression tree analysis was used to identify patient groups with varying risks of POMI. In each subgroup, the number needed to screen to identify 1 patient with POMI was calculated. POMI occurred in 216 (4%) patients and other myocardial injury in 842 (15%) of the 5590 included patients. Classification and regression tree analysis divided patients into 14 subgroups in which the risk of POMI ranged from 1.7% to 42%. Using a risk of POMI ≥2% to select patients for routine troponin I monitoring, this monitoring would be advocated in patients ≥60 years of age undergoing emergency surgery, or those undergoing elective surgery with a Revised Cardiac Risk Index class >2 (ie >1 risk factor). The number needed to screen to detect a patient with POMI would be 14 (95% CI 14–14) and 26% of patients with POMI would be missed. Conclusions To improve selection of high‐risk patients ≥60 years of age, routine postoperative troponin I monitoring could be considered in patients undergoing emergency surgery, or in patients undergoing elective surgery classified as having a revised cardiac risk index class >2.

Abstract Background: Many patients scheduled for elective surgery are referred for a preoperative medical consultation. Only limited data are available on factors associated with preoperative consultations. The authors hypothesized that surgical specialty contributes to variation in referrals for preoperative consultations. Methods: This is a cohort study using data from Group Health Cooperative, an integrated healthcare system. The authors included 13,673 patients undergoing a variety of common procedures—primarily low-risk surgeries—representing six surgical specialties, in 2005–2006. The authors identified consultations by family physicians, general internists, pulmonologists, or cardiologists in the 42 days preceding surgery. Multivariable logistic regression was used to estimate the association between surgical specialty and consultation, adjusting for potential confounders including the revised cardiac risk index, age, gender, Deyo comorbidity index, number of prescription medications, and 11 medication classes. Results: The authors found that 3,063 (22%) of all patients had preoperative consultations, with significant variation by surgical specialty. Patients having ophthalmologic, orthopedic, or urologic surgery were more likely to have consultations compared with those having general surgery—adjusted odds ratios (95% CI) of 3.8 (3.3–4.2), 1.5 (1.3–1.7), and 2.3 (1.8–2.8), respectively. Preoperative consultations were more common in patients with lower revised cardiac risk scores. Conclusion: There is substantial practice variation among surgical specialties with regard to the use of preoperative consultations in this integrated healthcare system. Given the large number of consultations provided for patients with low cardiac risk and for patients presenting for low-risk surgeries, their indications, the financial burden, and cost-effectiveness of consultations deserve further study.

Two benzofuran derivatives, chlorpromazine and amiodarone, are known to produce inclusion bodies in human tissues. Prolonged high dose chlorpromazine therapy causes hyperpigmentation of the skin with electron-dense inclusion bodies present in dermal histiocytes and endothelial cells ultrastructurally. The nature of the deposits is not known although a drug-melanin complex has been hypothesized. Amiodarone may also cause cutaneous hyperpigmentation and lamellar lysosomal inclusion bodies have been demonstrated within the cells of multiple organ systems. These lamellar bodies are believed to be the product of an amiodarone-induced phospholipid storage disorder. We performed transmission electron microscopy (TEM) and energy dispersive x-ray microanalysis (EDXA) on tissue samples from patients treated with these drugs, attempting to detect the sulfur atom of chlorpromazine and the iodine atom of amiodarone within their respective inclusion bodies.A skin biopsy from a patient with hyperpigmentation due to prolonged chlorpromazine therapy was fixed in 4% glutaraldehyde and processed without osmium tetroxide or en bloc uranyl acetate for Epon embedding.

Abstract This article addresses some criticisms of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) by comparing previously published outcome data from a group of complete spinal cord injury (SCI) persons with impairment ratings for a corresponding level of injury calculated using the AMA Guides, Sixth Edition. Results of the comparison show that impairment ratings using the sixth edition scale poorly with the level of impairments of activities of daily living (ADL) in SCI patients as assessed by the Functional Independence Measure (FIM) motor scale and the extended FIM motor scale. Because of the combinations of multiple impairments, the AMA Guides potentially overrates the impairment of paraplegics compared with that of quadriplegics. The use and applicability of the Combined Values formula should be further investigated, and complete loss of function of two upper extremities seems consistent with levels of quadriplegia using the SCI model. Some aspects of the AMA Guides contain inconsistencies. The concept of diminishing impairment values is not easily translated between specific losses of function per organ system and “overall” loss of ADLs involving multiple organ systems, and the notion of “catastrophic thresholds” involving multiple organ systems may support the understanding that variations in rating may exist in higher rating cases such as those that involve an SCI.
