Background: Pharmacokinetics and optimal dosing of piperacillin tazobactam (PT) have not been well studied in pediatric patients undergoing extracorporeal oxygenation membrane (ECMO).
Aim: To describe piperacillin plasmatic concentration and evaluate achievement of pharmaccokinetic/pharmacodinamic objective in patients on ECMO support.
Method: We report three pediatric patients admitted to the Pediatric Intensive Care Unit, treated with PT undergoing ECMO. Plasmatic concentrations of piperacillin were obtained in the middle of the dosing interval using high performance liquid chromatography.
Results: Plasmatic concentrations were 51,7-14,1 and 6,5 μg/mL for patient A, B and C respectively. Only one patient reached adequate concentrations.
Conclusion: These preliminary results suggest that availability of plasmatic concentrations of piperacillin could optimize the achievement of pharmacokinetic/pharmacodynamic objectives in pediatric patients on ECMO support.

Acute physical exercise and ambulatory blood pressure in resistant hypertension.
J Hypertens
November 2024
Faculty of Sport Sciences, Universidad Europea de Madrid.
Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.
Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.
The Relationship Between the Positive Drain Tip Cultures and the Incidence of Surgical Site Infection After Pediatric Cardiovascular Surgery.

Background: Surgical site infection (SSI) is a significant complication following pediatric cardiovascular surgery. Although drain tip cultures (DTC) are sometimes used postoperatively to predict SSIs, their diagnostic value in pediatric cardiovascular surgery remains unclear. This study aimed to assess the diagnostic utility of DTC for predicting SSIs in pediatric cardiovascular surgery patients.

Objective: CSF leaks are a significant source of patient morbidity following intradural spine surgeries. Watertight dural closure is crucial during these procedures to minimize the risk of a CSF leak. This study reports postoperative outcomes and changes in patient management after switching to penetrating titanium clips for dural closure in a large cohort of pediatric patients receiving a tethered cord release (TCR) or a selective dorsal rhizotomy (SDR).

Objective: Ventricular shunt insertion is a common procedure in pediatric neurosurgical practice. In many areas of medicine there is a push toward rationalization of healthcare resources and a reduction in low-value tests or procedures. The intraoperative sampling of CSF at the time of shunt insertion is one traditional aspect of care that has not been rigorously evaluated.
