Physiological responses to endoscopic surgery in children

Area of Science:

• Pediatric Surgery
• Physiology
• Minimally Invasive Procedures

Background:

• Limited understanding of the physiological impact of endoscopic surgery in pediatric patients.
• Pneumoperitoneum, used in endoscopic procedures, significantly affects cardiovascular dynamics.
• Key factors include increased intraabdominal pressure, CO2 absorption, and neurohumoral stimulation.

Purpose of the Study:

• To investigate the physiological effects of endoscopic surgery in infants and children.
• To assess cardiovascular, renal, and cerebral responses to pneumoperitoneum.
• To evaluate postoperative immune function and overall tolerance in pediatric patients.

Main Methods:

• Review of physiological parameters during and after endoscopic surgery in pediatric populations.
• Analysis of cardiovascular changes (heart rate, blood pressure, ventricular volumes, wall stress).
• Assessment of urine production, cerebral oxygenation, and blood flow, alongside immune function markers.

Main Results:

• Pneumoperitoneum in infants alters heart rate, mean arterial pressure, left ventricular volumes, and wall stress.
• Significant reduction in urine production observed.
• Cerebral oxygenation and blood flow are affected by the procedure.
• Postoperative immune function is preserved or restored more rapidly.
• Otherwise healthy infants and children generally tolerate these physiological responses well.

Conclusions:

• Endoscopic surgery induces notable physiological changes in infants and children.
• While cardiovascular and renal functions are impacted, healthy pediatric patients demonstrate good tolerance and immune recovery.
• Further research is needed to understand effects in children with comorbidities like sepsis or cancer.
