Congenital Heart Disease in Children, Fluid Overload, Surgery
Conditions
Brief summary
The intraoperative fluid balance during pediatric cardiac surgery is a very sensitive parameter given the low circulating volume and the complexity of anesthetic management but might be deleterious if inadequately managed. The hypothesis is that a highly positive intraoperative fluid balance increases the incidence of adverse events in the short and long term. A retrospective observational study including all consecutive children admitted for cardiac surgery with cardiopulmonary bypass (CPB) from 2008 to 2018 in a tertiary children's hospital will be performed. A multivariate analysis will be carried out to study the effect of the fluid balance on the incidence of adverse events.
Interventions
DRUGFluid balance
The intervention consists of classic and standardized anesthesia management of children undergoing cardiac surgery. All the data links to the fluid management will be extracted from the patient's chart in the intraoperative period as well as complications during the hospitalization in the postoperative period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Severe postoperative morbidity | From intervention until 28 days postoperatively | Severe postoperative morbidity will be characterized as the presence of two or more of the following situations: respiratory failure, prolonged inotropic support, or renal failure. Respiratory failure will be defined as the requirement for mechanical ventilation for \>82 hours at any time from Pediatric Intensive Care Unit admission to the time of tracheal extubation. Prolonged inotropic support will be characterized as hemodynamic support by continuous vasoactive drug infusion for \>48 hours postoperatively (excluding dopamine or dobutamine ≤5 μg/kg/min). Renal failure will be characterized as the worst estimated postoperative creatinine clearance (eCCr) value showing a ≥75% reduction compared with the preoperative baseline eCCr. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of new Neurological deficits | From intervention until 28 days postoperatively | Neurological deficit will be characterized as a transient or permanent functional abnormality in a body region due to a reduction of brain function. The measurement will be the incidence of ischemic stroke, hemorrhagic stroke and cognitive dysfunctions. |
| Incidence of new infections | From intervention until 28 days postoperatively | Infection will be characterized as the need for antibiotics other than the usual anti-staphylococcal prophylaxis initiated by the attending intensive care physician for a suspected or proven infection caused by any pathogen or for a clinical syndrome associated with a high probability of infection. Measurement will be the number of patients with new infections corresponding to this definition. |
| Duration of mechanical ventilation | From intervention until 28 days postoperatively | Delay between the end of the operation and the extubation of the patient. |
| PICU and hospital length of stay | From intervention until 28 days postoperatively | Delay between the end of the operation and the exit of the patient of the Pediatric Intensive care Unit and the delay between the end of the operation and the exit of the institution. |
