Wake Up Safe and root cause analysis: quality improvement in pediatric anesthesia.

In 2006, the Quality and Safety Committee of the Society for Pediatric Anesthesia initiated a quality improvement project for the specialty of pediatric anesthesiology that ultimately resulted in the development of Wake Up Safe (WUS), a patient safety organization that maintains a registry of de-identified, serious adverse events. The ultimate goal of WUS is to implement change in processes of care that improve the quality and safety of anesthetic care provided to pediatric patients nationwide. Member institutions of WUS submit data regarding the types and numbers of anesthetics performed and information pertaining to serious adverse events. Before a member institution submits data for any serious adverse event, 3 anesthesiologists who were not involved in the event must analyze the event with a root cause analysis (RCA) to identify the causal factor(s). Because institutions across the country use many different RCA methods, WUS educated its members on RCA methods in an effort to standardize the analysis and evaluate each serious adverse event that is submitted. In this review, we summarize the background and development of this patient safety initiative, describe the standardized RCA method used by its members, demonstrate the use of this RCA method to analyze a serious event that was reported, and discuss the ways WUS plans to use the data to promote safer anesthetic practices for children.

Cardiac medications are not associated with clinically important preoperative electrolyte disturbances in children presenting for cardiac surgery.

BACKGROUND: Preoperative laboratory examination of patients undergoing elective surgical procedures has been routinely performed for decades. Although there is a large body of literature concerning the appropriate preoperative assessment of adult patients, corresponding literature for the pediatric population is not as well defined. Children and young adults with cardiac disease are a particularly vulnerable subset of patients who often undergo an extensive battery of preoperative laboratory testing. We examined the serum chemistry profiles for children with cardiac disease presenting for outpatient surgery. The investigation aims to define the effectiveness of preoperative electrolyte determination in this population of children and young adults. METHODS: A retrospective chart review of all children presenting as outpatients to a tertiary care, freestanding children's hospital for elective cardiac surgery between January 1, 2000 and January 31, 2003 was performed. All patient charts in which the admission date matched the cardiac surgical date were examined. Patients were excluded if the preoperative laboratory evaluation was performed outside of our facility, preoperative laboratory investigation was not performed, or the patient was transported by medical transport to our hospital. Patients were grouped according to three methods: the number of cardiac medications (none to four), and cardiac medications, noncardiac medications, and no medications. The presence of electrolyte abnormalities was also examined in the context of cardiac medications with various pharmacologic effects. The primary outcome measure was the incidence of abnormal laboratory values for children taking various cardiac medications. RESULTS: Of the 933 initial entries found, 774 met the investigational criteria and were included in the analysis. Although statistically significant differences in preoperative electrolytes were associated with the use of cardiac and noncardiac medication, there was no clinical value to this correlation. The data demonstrate a very low incidence of hypokalemia and hypomagnesemia in the entire study population. CONCLUSION: Preoperative electrolyte disturbances in children and young adults presenting for cardiac surgery are uncommon. The concern of hypokalemia or hypomagnesemia important in the adult population taking cardiac medications was not identified in the pediatric population. These data do not support the need for routine preoperative electrolyte evaluation in children taking cardiac medications.

An unusual cause of arterial desaturation in the premature infant undergoing patent ductus arteriosus ligation.

IMPLICATIONS: A premature infant undergoing ligation of a patent ductus arteriosus had arterial desaturation during surgical retraction, which was caused by a previously unrecognized vascular ring anomaly.

New treatments for perioperative cardiac arrhythmias.

Cardiac arrhythmias remain a major source of morbidity, mortality, and prolonged postoperative hospital stay in surgical patients. Recent studies in patients experiencing out-of-hospital cardiac arrest have expanded our knowledge in the management of cardiac arrhythmias. Future advances require additional studies focused on the unique proarrhythmic substrates in surgical patients, to provide a clear rationale for antiarrhythmic drug therapy in the perioperative period.
