Pediatric laparoscopy and adaptive oxygenation and hemodynamic changes

Pediatric Laparoscopy and Adaptive Oxygenation and Hemodynamic Changes

Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insuf...

Laparoscopy and pediatric urology

Minimally invasive surgery has became in the recent years a synonyme of laparoscopic surgery. It may be simply attributed to the significant advances in surgical technique worldwide. However it must be stated that laparoscopy has not found such a wide application in pediatric urology, as in other surgical specialities. The manuscript “The retroperitoneal approach to distal part of the ureter [1...

Dynamic changes of hemodynamic parameters and cardiac transcription of sirtuins in adaptive and mal-adaptive phases of pressure overload-induced hypertrophy in rats

Introduction: The aim of the study was to investigate the structural and hemodynamic changes as well as cardiac transcriptional profile of the key regulatory proteins, sirtuins family (SIRT1-7), in adaptive and mal-adaptive phases of left ventricular hypertrophy (LVH). Methods: LVH was induced in male Wistar rats (190±20g) by abdominal aortic banding. The third and sixteenth weeks post-surgery ...

Hemodynamic changes induced by laparoscopy and their endocrine correlates: effects of clonidine.

OBJECTIVES We investigated endocrine correlates of the hemodynamic changes induced by carbon dioxide pneumoperitoneum (PNO). We then studied whether clonidine might modulate the hemodynamic changes induced by PNO by reducing release of catecholamines and vasopressin. BACKGROUND Both mechanical and neurohumoral factors contribute to the hemodynamic changes induced by carbon dioxide PNO. Severa...
