RESUMO

PURPOSE: Intraoperative hypoglycemia can result in devastating neurologic injury if not promptly diagnosed and treated. Few studies have defined risk factors for intraoperative hypoglycemia. The authors sought to characterize children with intraoperative hypoglycemia and determine independent risk factors. METHODS: This retrospective observational single-institution study included all patients < 18 yr of age undergoing an anesthetic from January 1 2012 to December 31 2016. The primary outcome was blood glucose < 3.3 mmol·L-1 (60 mg·dl-1). Data collected included patient characteristics, comorbidities, and intraoperative factors. A multivariable logistic regression model was used to identify independent predictors of intraoperative hypoglycemia. RESULTS: Blood glucose was measured in 7,715 of 73,592 cases with 271 (3.5%) having a glucose < 3.3 mmol·L-1 (60 mg·dl-1). Young age, weight for age < 5th percentile, developmental delay, presence of a gastric or jejunal tube, and abdominal surgery were identified as independent predictors for intraoperative hypoglycemia. Eighty percent of hypoglycemia cases occurred in children < three years of age and in children < 15 kg. CONCLUSION: Young age, weight for age < 5th percentile, developmental delay, having a gastric or jejunal tube, and abdominal surgery were independent risk factors for intraoperative hypoglycemia in children. Frequent monitoring of blood glucose and judicious isotonic dextrose administration may be warranted in these children.

RESUMO

We sought to assess acute hemodynamic changes after implementation of negative extrathoracic pressure (NEP) in spontaneously breathing ambulatory Fontan patients with symptomatic heart failure. We hypothesized that application of NEP would result in an acute decrease in pulmonary artery pressure. Ten patients with clinical evidence of Fontan failure underwent baseline hemodynamic catheterization while breathing spontaneously. Hemodynamic measurements were then repeated after 30 min of continuous NEP. After 30 min of continuous NEP, 4/10 patients had a decrease in their Fontan pressure by 2 mmHg and one patient had a decrease by 1 mmHg. There were three patients that had an increase in Fontan pressure by 2 mmHg. In 7/10 patients, indexed pulmonary vascular resistance decreased by an average of 31%. In symptomatic Fontan patients with a favorable hemodynamic response to NEP during catheterization, potential benefit of longer-term NEP to improve clinical status should be explored.

RESUMO

Current practice of sedation and anesthesia for patients undergoing pediatric and congenital cardiac catheterization laboratory (PCCCL) procedures is known to vary among institutions, a multi-society expert panel with representatives from the Congenital Heart Disease Council of the Society for Cardiovascular Angiography and Interventions, the Society for Pediatric Anesthesia and the Congenital Cardiac Anesthesia Society was convened to evaluate the types of sedation and personnel necessary for procedures performed in the PCCCL. The goal of this panel was to provide practitioners and institutions performing these procedures with guidance consistent with national standards and to provide clinicians and institutions with consensus-based recommendations and the supporting references to encourage their application in quality improvement programs. Recommendations can neither encompass all clinical circumstances nor replace the judgment of individual clinicians in the management of each patient. The science of medicine is rooted in evidence, and the art of medicine is based on the application of this evidence to the individual patient. This expert consensus statement has adhered to these principles for optimal management of patients requiring sedation and anesthesia. What follows are recommendations for patient monitoring in the PCCCL regardless of whether minimal or no sedation is being used or general anesthesia is being provided by an anesthesiologist.

RESUMO

UNLABELLED: Acute kidney injury (AKI) is a serious complication that occurs commonly following cardiopulmonary bypass (CPB) in infants and children. Underlying risk factors for AKI remain unclear, given changes in CPB practices during recent years. This retrospective, case-control study examined the relationships between patient, perioperative factors, AKI, and kidney failure in children who underwent CPB. METHODS: Cohorts of children with and without AKI were identified from the cardiac perfusion and nephrology consult databases. Demographic, perioperative, and postoperative outcome data were extracted from the databases and from medical records. Children were stratified into groups based on the Acute Dialysis Quality Initiative's RIFLE definitions for acute kidney risk or injury (AKI-RI) and kidney failure. RESULTS: The study groups included 308 controls (no AKI-RI or failure), 161 with AKI-RI, and 89 with failure. Young age, preoperative need for mechanical ventilation, milrinone, or gentamicin; intraoperative use of milrinone and furosemide; durations of CPB and anesthesia; multiple cross-clamp and transfusion of blood products were significantly associated with AKI or failure. Young age, perioperative use of milrinone, multiple cross-clamps, extracorporeal membrane oxygenation, cardiac failure, neurological complications, sepsis, and failure significantly increased the odds of mortality. CONCLUSION: This study identified multiple perioperative risk factors for AKI-RI, failure, and mortality in children undergoing CPB. In addition to commonly known risk factors, perioperative use of milrinone, particularly in young infants, and furosemide were independently predictive of poor renal outcomes in this sample. Findings suggest a need for the development of protocols aimed at renal protection in specific at risk patients.

RESUMO

BACKGROUND: Otherwise healthy children who present for elective surgery with an upper respiratory infection (URI) may be at risk for perioperative respiratory complications. This risk may be increased in children with congenital heart disease who undergo cardiac surgery while harboring a URI because of their compromised cardiopulmonary status. Therefore, this study was designed to determine the incidence of peri- and postoperative complications in children undergoing cardiac surgery while harboring a URI. METHODS: The study population consisted of 713 children scheduled to undergo cardiac surgery. Of these, 96 had symptoms of URI, and 617 were asymptomatic. Children were followed prospectively from induction of anesthesia to discharge from the hospital to determine the incidence of postoperative respiratory, cardiovascular, neurologic, and surgical adverse events. Duration of postoperative ventilation, time in the intensive care unit (ICU), and length of hospital stay were also recorded. RESULTS: Children with URIs had a significantly higher incidence of respiratory and multiple postoperative complications than children with no URIs (29.2 vs 17.3% and 25 vs 10.3%, respectively; P< 0.01) and a higher incidence of postoperative bacterial infections (5.2 vs 1.0%; P= 0.01). Furthermore, logistic regression indicated that the presence of a URI was an independent risk factor for multiple postoperative complications and postoperative infections in children undergoing open heart surgery. Children with URIs also stayed longer in the intensive care unit than children with no URIs (75.9 +/- 89.8 h vs 57.7 +/- 63.8, respectively; P< 0.01). However, the overall length of hospital stay was not significantly different (8.4 vs 7.8 days, URI vs non-URI groups; P> 0.05). CONCLUSIONS: The presence of a URI was predictive of postoperative infection and multiple complications in children presenting for cardiac surgery. Despite this, the presence of a URI does not appear to affect the patient's overall length of hospital stay nor the development of long-term sequelae.

RESUMO

OBJECTIVE: To determine the effects of adding 5% albumin to the cardiopulmonary bypass prime on perioperative fluid status and fluid management in young children. DESIGN: Prospective randomized study. SETTING: Single university hospital. PATIENTS: Pediatric patients of <14 kg undergoing cardiac surgery requiring cardiopulmonary bypass. INTERVENTIONS: Patients received a 5% albumin prime or a crystalloid prime. Perioperative fluid intake, output, and daily weights were recorded. Serial hematocrits, colloid osmotic pressures, and serum albumins were measured. Outcomes and complications were documented. MEASUREMENTS AND MAIN RESULTS: There were 86 patients aged 3 days to 4 yrs; 44 patients had an albumin prime and 42 had a crystalloid prime. Patients in the albumin group had a net negative fluid balance at the end of cardiopulmonary bypass compared with a net positive fluid balance in the crystalloid group. Patients in the albumin group had significantly higher serum albumins and colloid osmotic pressures and gained less weight postoperatively. However, their hematocrits were lower, and more patients in the albumin group received packed red blood cells. By 24 hrs postoperatively, there were no differences in colloid osmotic pressures and hematocrits between groups, and by the fourth postoperative day, there was no difference in weight gain. No differences were found in length of mechanical ventilation, intensive care unit or hospital stay, complications, or mortality. CONCLUSIONS: Albumin in the prime may attenuate the extravasation of fluid out of the vascular space, but it may be associated with an increased transfusion rate. The risk/benefit ratio for this intervention warrants further study.
