No Association of Early Postoperative Heart Rate With Outcomes After Coronary Artery Bypass Grafting.

BACKGROUND: Elevated perioperative heart rate potentially causes perioperative myocardial injury because of imbalance in oxygen supply and demand. However, large multicenter studies evaluating early postoperative heart rate and major adverse cardiac and cerebrovascular events (MACCEs) are lacking. OBJECTIVE: To assess the associations of 4 postoperative heart rate assessment methods with in-hospital MACCEs after elective coronary artery bypass grafting (CABG). METHODS: Using data from the eICU Collaborative Research Database in the United States from 2014 to 2015, the study evaluated postoperative heart rate measured during hospitalization within 24 hours after intensive care unit admission. Four heart rate assessment methods were evaluated: maximum heart rate, duration above heart rate 100/min, area above heart rate 100/min, and time-weighted average heart rate. The outcome was in-hospital MACCEs, defined as a composite of in-hospital death, myocardial infarction, angina, arrhythmia, heart failure, stroke, cardiac arrest, or repeat revascularization. RESULTS: Among 2585 patients, the crude rate of in-hospital MACCEs was 6.2%. In multivariable logistic regression analysis, the adjusted odds ratios (95% CI) for in-hospital MAC-CEs assessed by maximum heart rate in each heart rate category (beats per minute: >100-110, >110-120, >120-130, and >130) were 1.43 (0.95-2.15), 0.98 (0.56-1.64), 1.47 (0.76-2.69), and 1.71 (0.80-3.35), respectively. Similarly, none of the other 3 methods were associated with MACCEs. CONCLUSIONS: More research is needed to assess the usefulness of heart rate measurement in patients after CABG.

Standardized Perioperative Note to Improve Perioperative Management of Patients With Cardiac Implantable Electronic Devices.

PURPOSE: Over 3 million people have a cardiac implantable electronic device (CIED) in the United States. Without an organization-wide, standardized approach to the perioperative management of patients with CIEDs, communication errors and subsequent periods of unintentional deactivation and management can leave patients vulnerable to untreated, life-threatening arrhythmias. The purpose of this quality improvement project was to refine the standardized approach for perioperative management of patients with CIEDs at a large academic medical center. DESIGN: A pre-post implementation design with two independent groups. METHODS: Patients with preexisting permanent CIEDs (n = 405) undergoing surgical and nonsurgical procedures with anesthesia were included. A preprocedure note was revised and implemented in the electronic health record for patients with CIEDs to include information about the device type, perioperative plan, and contact information for technical support. FINDINGS: When the preprocedure note was used, completion of the perioperative plan and contact information increased significantly (P < .001) and the number of undocumented interventions that occurred with CIEDs in the intraoperative period (magnet use, preoperative reprogramming, and postoperative reprogramming) was significantly reduced (P < .05). CONCLUSIONS: While documentation of the preprocedure note and intraoperative interventions increased, ongoing perioperative management improvements for patients with CIEDs are needed.

Association Between Gabapentinoids and Postoperative Pulmonary Complications in Patients Undergoing Thoracic Surgery.

OBJECTIVE: Perioperative gabapentinoids in general surgery have been associated with an increased risk of postoperative pulmonary complications (PPCs), while resulting in equivocal pain relief. This study's aim was to examine the utilization of gabapentinoids in thoracic surgery to determine the association of gabapentinoids with PPCs and perioperative opioid utilization. DESIGN: A multicenter retrospective cohort study. SETTING: Hospitals in the Premier Healthcare Database from 2012 to 2018. PARTICIPANTS: A total of 70,336 patients undergoing elective open thoracotomy, video-assisted thoracic surgery, and robotic-assisted thoracic surgery. INTERVENTIONS: Propensity score analyses were used to assess the association between gabapentinoids on day of surgery and the primary composite outcome of PPCs, defined as respiratory failure, pneumonia, reintubation, pulmonary edema, and noninvasive and invasive ventilation. Secondary outcomes included invasive and noninvasive ventilation, hospital mortality, length of stay, opioid consumption on day of surgery, and average daily opioid consumption after day of surgery. RESULTS: Overall, 8,142 (12%) patients received gabapentinoids. The prevalence of gabapentin on day of surgery increased from 3.8% in 2012 to 15.9% in 2018. Use of gabapentinoids on day of surgery was associated with greater odds of PPCs (odds ratio [OR] 1.19, 95% CI 1.11-1.28), noninvasive mechanical ventilation (OR 1.30, 95% CI 1.16-1.45), and invasive mechanical ventilation (OR 1.14, 95% CI 1.02-1.28). Secondary outcomes indicated no clinically meaningful associations of gabapentinoid use with opioid consumption, hospital mortality, or length of stay. CONCLUSIONS: Perioperative gabapentinoid administration in elective thoracic surgery may be associated with a higher risk of PPCs and no opioid-sparing effect.

Implementation of a Postoperative Electronic Health Record Alert for Cardiac Implantable Electronic Device Patients.

PURPOSE: Approximately 2% of surgical patients have an existing cardiac implantable electronic device (CIED). Perioperative device reprogramming requires postoperative care to ensure that device settings are restored. Electronic health record (EHR) alerts have been shown to improve communication between providers and decrease time to necessary interventions in other areas of medicine. The aim of this quality improvement project was to create an EHR alert for postoperative CIED patients who require device reprogramming to help clinicians track, remember, and document the timely and safe restoration of device settings. DESIGN: This project used a pre-post observational design. METHODS: This project was conducted at a major academic medical center using a pre-post observational design. To prevent anesthesia providers from closing an encounter in the EHR before postoperative restoration of device settings, an alert was developed and embedded within the intraoperative EHR to track preoperative device reprogramming, and alert anesthesia providers to perform and document postoperative restoration of safe settings. FINDINGS: The postimplementation group (n = 272) had fewer unknown or undocumented preoperative CIED interventions (12.9% vs 30.9%), a 7.3% shorter device suspension time (median = 165 minutes vs 178 minutes), 6.8% improvement in documentation of postoperative re-enabling of device therapies (78.8% vs 72.0%), and a 72.48% decrease in length of stay (median = 625 hours vs 172 hours) when compared with the preimplementation group (n = 132). CONCLUSION: Electronic prompts effectively captured patients who received preoperative CIED reprogramming and provided a process for reprogramming devices to safe settings, both significant steps in preventing negative patient outcomes associated with undocumented CIED interventions. Perioperative CIED documentation improved, and length of stay decreased after project implementation.

Changes in analgesic strategies for lobectomy from 2009 to 2018.

Objective: To evaluate trends in the use of epidural analgesia and nonopioid and opioid analgesics for patients undergoing lobectomy from 2009 to 2018. Methods: We queried the Premier database for adult patients undergoing open, video-assisted, and robotic-assisted lobectomy from 2009 to 2018. The outcome of interest was changes in the receipt of epidural analgesia and nonopioid and opioid analgesics as measured by charges on the day of surgery. We also evaluated postoperative daily opioid use. We used multivariable logistic and linear regression models to examine the association between the utilization of each analgesic modality and year. Results: We identified 86,308 patients undergoing lobectomy from 2009 to 2018 within the Premier database: 35,818 (41.5%) patients had open lobectomy, 35,951 (41.7%) patients had video-assisted lobectomy, and 14,539 (16.8%) patients had robotic-assisted lobectomy. For all 3 surgical cohorts, epidural analgesia use decreased, and nonopioid analgesics use increased over time, except for intravenous nonsteroidal anti-inflammatory drugs. Use of patient-controlled analgesia decreased, while opioid consumption on the day of surgery increased and postoperative opioid consumption did not decrease over time. Conclusions: In this large sample of patients undergoing lobectomy, utilization of epidural analgesia declined and use of nonopioid analgesics increased. Despite these changes, opioid consumption on day of surgery increased, and there was no significant reduction in postoperative opioid consumption. Further research is warranted to examine the association of these changes with patient outcomes.

Intraoperative renal resistive index threshold as an acute kidney injury biomarker.

STUDY OBJECTIVE: The lag in creatinine-mediated diagnosis of cardiac surgery-associated acute kidney injury (AKI) may be impeding the development of renoprotection therapies. Postoperative renal resistive index (RRI) measured by transabdominal Doppler ultrasound is a promising early AKI biomarker. RRI measured intraoperatively by transesophageal echocardiography (TEE) is available even earlier but is less evaluated. Therefore, we conducted an assessment of intraoperative RRI as an AKI biomarker using previously reported post-renal insult thresholds. DESIGN: Retrospective convenience sample. SETTING: Intraoperative. PATIENTS: 180 adult cardiac surgical patients between July 2013 and July 2014. INTERVENTION: None. MEASUREMENTS: Pre- and post-cardiopulmonary bypass (CPB) RRI thresholds, measured using intraoperative TEE, exceeding 0.74 or 0.79 were used to evaluate for an association with KDIGO AKI risk using the Chi-square test. Other consensus AKI criteria (AKIN, RIFLE) were similarly evaluated. Additional t-test analyses examined the relationship of pre- and pre-to-post (delta) CPB RRI with AKI. MAIN RESULTS: Post-CPB RRI for 99 patients included 36 and 23 with values exceeding 0.74 and 0.79, respectively. Analyses confirmed associations of both RRI thresholds with all consensus AKI definitions (0.74; KDIGO: p = 0.05, AKIN: p = 0.03, RIFLE: p = 0.03, 0.79; KDIGO: p = 0.002, AKIN: p = 0.001, RIFLE: p = 0.004). In contrast, pre-CPB and pre-to post-CPB RRI were not associated with AKI. CONCLUSIONS: RRI obtained intraoperatively in cardiac surgery patients, assessed using previously reported thresholds, is highly associated with AKI and warrants further evaluation as a promising "earliest" AKI biomarker. These significant findings suggest that RRI assessment should be included in the standard intraoperative TEE exam.

Perioperative Quality Initiative consensus statement on preoperative blood pressure, risk and outcomes for elective surgery.

BACKGROUND: A multidisciplinary international working subgroup of the third Perioperative Quality Initiative consensus meeting appraised the evidence on the influence of preoperative arterial blood pressure and community cardiovascular medications on perioperative risk. METHODS: A modified Delphi technique was used, evaluating papers published in MEDLINE on associations between preoperative numerical arterial pressure values or cardiovascular medications and perioperative outcomes. The strength of the recommendations was graded by National Institute for Health and Care Excellence guidelines. RESULTS: Significant heterogeneity in study design, including arterial pressure measures and perioperative outcomes, hampered the comparison of studies. Nonetheless, consensus recommendations were that (i) preoperative arterial pressure measures may be used to define targets for perioperative management; (ii) elective surgery should not be cancelled based solely upon a preoperative arterial pressure value; (iii) there is insufficient evidence to support lowering arterial pressure in the immediate preoperative period to minimise perioperative risk; and (iv) there is insufficient evidence that any one measure of arterial pressure (systolic, diastolic, mean, or pulse) is better than any other for risk prediction of adverse perioperative events. CONCLUSIONS: Future research should define which preoperative arterial pressure values best correlate with adverse outcomes, and whether modifying arterial pressure in the preoperative setting will change the perioperative morbidity or mortality. Additional research should define optimum strategies for continuation or discontinuation of preoperative cardiovascular medications.

Implementation of an Innovative Residency Leadership Development Curriculum.

The role of the anesthesiologist in the perioperative environment requires facility in leadership; however, leadership education is not part of the traditional curriculum for anesthesiology trainees. To address this educational gap, we developed a leadership program for anesthesiology residents at an academic medical center to build competency in the areas of teamwork, emotional intelligence, integrity, selfless service, critical thinking, and patient-centeredness, constructs that correlate with the Accreditation Council for Graduate Medical Education competencies of interpersonal and communication skills and professionalism. This report describes the design and implementation of the program, including the curriculum, and offers recommendations for implementation at other institutions.
