The implementation of a pectus bar insertion enhanced recovery after surgery pathway: A quality improvement initiative.

BACKGROUND: Pectus excavatum repair is associated with significant discomfort, and pain is a primary contributor to postoperative hospital length of stay. Recent advances in postoperative pain control include the use of intercostal cryoablation techniques that may now make it possible to discharge patients on the day of surgery. Unnecessary variation in patient care and noncompliance with care bundles may be a factor in extended length of stay. The global aim of this quality improvement initiative was to successfully implement an enhanced recovery after surgery (ERAS) pathway on patients undergoing pectus excavatum repair. The SMART aim was to have a greater than 70% compliance for the perioperative bundle elements within 1 year of the pathway implementation. METHODS: Multiple Plan-Do-Study-Act (PDSA) cycles were designed to create and implement an ERAS pathway for patients undergoing a pectus bar insertion procedure. This multidisciplinary pathway was designed, managed, and implemented with key stakeholders from the Departments of Evidence Based Practice, Surgery, Anesthesiology, and Perioperative Nursing. Patient characteristics, outcomes, and compliance with elements of the pathway were measured for analysis for both the baseline and post-intervention groups with monthly automated reports. RESULTS: After implementation of the ERAS pathway, data on the first 50 patients showed a 90% compliance with the perioperative bundle elements. Mean length of stay was significantly decreased from 33 h (95% CI [28.76, 37.31]) to 18 h (95% CI [14.54, 21.70]). There were zero readmissions within 24 hours for patients who were discharged on the day of surgery. CONCLUSION: Employing a multidisciplinary approach in both planning and execution that standardized clinician practices and minimized unnecessary variation in patient care, an ERAS pathway for pectus bar insertion has been successfully established at our institution.

Vaping Associated Cardiac Arrest at School in a Teenager with Anomalous Left Coronary Artery.

The prevalence of electronic cigarette use is increasing at an astonishing pace, particularly in the teenage population. While at school, a healthy 13-year-old male experienced a sudden cardiac arrest after vaping multiple times throughout the day. Workup revealed an anomalous left coronary artery originating from the right sinus of Valsalva. Given this patient's underlying anomalous left coronary artery, we suspect that sympathoexcitatory and arrhythmogenic effects of high dose nicotine from vaping led to his cardiovascular collapse. This is the first published case report of a vaping associated cardiac arrest in a patient of this age.

Trimmed central venous catheters in pediatric cardiac surgery: Does height or weight correlate with the amount trimmed?

BACKGROUND: Due to excess catheter length, pediatric patients undergoing cardiac surgery frequently have the tip of the central venous catheter trimmed while on bypass to obtain optimal catheter positioning. AIMS: We sought to determine if there is a correlation between the patient's height or weight and the length of catheter removed. Our secondary aim compared the instances of central line-associated bloodstream infections and venous thromboembolisms between the trimmed and untrimmed catheters. METHODS: This retrospective study included patients having undergone cardiac surgery over a 3-year period who had an 8 cm central venous catheter placed in the right internal jugular vein. Hospital lists of central line-associated bloodstream infections and venous thromboembolisms that occurred were cross referenced with our study patients. RESULTS: There were 147 cases where the 8 cm central venous catheter was trimmed, which represents 35% of the cases. Of the catheters that were cut, on average 2.17 cm was removed. There is negligible correlation between the length of catheter removed and patient height (r = -.19, p = .021). There is negligible correlation between the length of catheter removed and patient weight (r = -.17, p = .039). There were no instances of central line-associated bloodstream infections or venous thromboembolisms attributed to the trimmed catheters. Of the 273 untrimmed catheters, there were no instances of an infection and one instance of a venous thromboembolism. CONCLUSION: Right internal jugular 8 cm central venous catheters are trimmed during pediatric cardiac surgery, and there is minimal correlation between the length removed and the patient height or weight. Due to the difficulty in estimating the proper length of a central venous catheter in smaller pediatric patients, placing an 8 cm long catheter in these patients and then trimming the distal tip while on bypass may be the most accurate way to properly position a catheter.

The implementation of low-flow anesthesia at a tertiary pediatric center: A quality improvement initiative.

INTRODUCTION: Anesthesia machines have evolved over the years to excel in delivering low-flow anesthesia (<1 L fresh gas flow) in a closed-circuit system, with the obvious benefits being decreased costs and reduced emissions of greenhouse gases. At a pediatric hospital that provides over 25 000 anesthetics a year, a quality improvement project was initiated with the aim of decreasing the amount of sevoflurane used per anesthetic by 20% over the course of a year. METHODS: Three Plan-Do-Study-Act cycles involving gathering comparative data, departmental education, improvement updates on our huddle board, and intraoperative confirmation rounds were completed. The bottles of sevoflurane used and the total number of anesthetics performed were collected each month. To account for the fluctuation of anesthetic cases per month, a metric of "Anesthetics Performed per Bottle of Sevoflurane Used" was created. RESULTS: Compared to a prior twelve-month period, the Anesthetics Performed per Bottle of Sevoflurane Used were higher with a mean increase of 25%. The bottles of sevoflurane used per month was lower with a mean decrease of 20%. The carbon footprint of our sevoflurane use was also decreased and extrapolated over a year, and the decrease was equivalent to 70 000 miles driven, over 3,200 gallons of gasoline consumed, or over 31000 pounds of coal burned. CONCLUSION: A QI initiative aimed at changing the practice of delivering at least 2L fresh gas flow to delivering a low-flow anesthetic has been a successful value-added enhancement to our pediatric anesthesia practice.

Breathing circuit compliance and accuracy of displayed tidal volume during pressure-controlled ventilation of infants: A quality improvement project.

INTRODUCTION: Anesthesia machines have evolved to deliver desired tidal volumes more accurately by measuring breathing circuit compliance during a preuse self-test and then incorporating the compliance value when calculating expired tidal volume. The initial compliance value is utilized in tidal volume calculation regardless of whether the actual compliance of the breathing circuit changes during a case, as happens when corrugated circuit tubing is manually expanded after the preuse self-test but before patient use. We noticed that the anesthesia machine preuse self-test was usually performed on nonexpanded pediatric circuit tubing, and then the breathing circuit was subsequently expanded for clinical use. We aimed to demonstrate that performing the preuse self-test in that manner could lead to incorrectly displayed tidal volume on the anesthesia machine monitor. The goal of this quality improvement project was to change the usual practice and improve the accuracy of displayed tidal volume in infants undergoing general anesthesia. METHODS: There were four stages of the project: (i) gathering baseline data about the performance of the preuse self-test and using infant and adult test lungs to measure discrepancies of displayed tidal volumes when breathing circuit compliance was changed after the initial preuse self-test; (ii) gathering clinical data during pressure-controlled ventilation comparing anesthesia machine displayed tidal volume with actual spirometry tidal volume in patients less than 10 kg before (machine preuse self-test performed while the breathing circuit was nonexpanded) and after an intervention (machine preuse self-test performed after the breathing circuit was fully expanded); (iii) performing department-wide education to help implement practice change; (iv) gathering postintervention data to determine the prevalence of proper machine preuse self-test. RESULTS: At constant pressure-controlled ventilation through fully expanded circuit tubing, displayed tidal volume was 83% greater in the infant test lung (mean±SD TV 15±5 vs 9±4 mL; mean [95% CI] difference=6.3 [5.6, 7.1] mL, P<.0001) and 3% greater in the adult test lung (245±74 vs 241±72 mL; difference=5 [1, 10] mL, P=.0905) when circuit compliance had been measured with nonexpanded tubing compared to when circuit compliance was measured with fully expanded tubing. The clinical data in infants demonstrated that displayed tidal volume was 41% greater than actual tidal volume (difference of 10.4 [8.6, 12.2] mL) when the circuit was expanded after the preuse self-test (preintervention) and 7% greater (difference of 2.5 [0.7, 4.2] mL) in subjects when the circuit was expanded prior to the preuse self-test (postintervention) (P<.0001). Clinical practice was changed following an intervention of departmental education: the preuse self-test was performed on expanded circuit tubing 11% of the time prior to the intervention and 100% following the intervention. CONCLUSION: Performing a preuse self-test on a nonexpanded pediatric circuit that is then expanded leads to falsely elevated displayed tidal volume in infants less than 10 kg during pressure-controlled ventilation. Overestimation of reported tidal volume can be avoided by expanding the breathing circuit tubing to the length which will be used during a case prior to performing the anesthesia machine preuse self-test. After department-wide education and implementation, performing a correct preuse self-test is now the standard practice in our cardiac operating rooms.
