[The central hemodynamics and hormonal status before, during and after urologic operations in children]
Insights
Pediatric urological surgery requires careful anesthetic management. Monitoring cardiovascular and hormonal status during procedures like upper urinary tract reconstruction is crucial for patient safety and recovery.
Area of Science:
- Pediatric Urology
- Anesthesiology
- Pediatric Endocrinology
Background:
- Urological operations in children primarily address congenital malformations.
- Adequate anesthesiological defense is essential to prevent operative injury.
- Real-time monitoring of cardiovascular, oxygen metabolic, and hormonal status is vital for effective anesthesia.
Purpose of the Study:
- To summarize central hemodynamics, oxygen metabolism, and hormonal findings in pediatric patients undergoing urological surgery.
- To evaluate the impact of different anesthetic techniques on physiological parameters during upper urinary tract reconstruction.
Main Methods:
- Studied 89 children undergoing plastic reconstruction of the upper urinary tract.
- Measured central hemodynamics, oxygen metabolism, and hormonal levels before and during surgery.
- Compared effects of neuroleptanalgesia and balanced promedol analgesia.
Main Results:
- Initial hyperkinetic hemodynamics due to inadequate premedication shifted to stable/hypokinetic circulation with neuroleptanalgesia.
- Balanced promedol analgesia induced eukinetic trends.
- Hydrocortisone, aldosterone, and STH levels increased, while T3 and T4 levels decreased.
- Postoperative hemodynamics varied based on the anesthetic technique used.
Conclusions:
- Anesthetic management significantly influences hemodynamic and hormonal responses in children during urological surgery.
- Neuroleptanalgesia and balanced promedol analgesia have distinct effects on pediatric hemodynamics.
- Monitoring these physiological parameters is key to optimizing anesthetic care in pediatric urological procedures.
Abstract:
Urological operations in children are made as a rule to correct congenital malformations. The prevention of operative injury to the child' body is secured only in conditions of adequate anesthesiological defense. This is possible only in availability of rapid information on cardiovascular, oxygen metabolic and hormonal statuses. Central hemodynamics, oxygen metabolism and hormonal findings have been summarized for 89 children. The above parameters were measured before and during plastic reconstruction of the upper urinary tract. Initially hyperkinetic hemodynamics because of inadequate premedication to control psychoemotional lability, changed for stable and hypokinetic circulation to the end of the operative intervention as a result of neuroleptanalgesia. Eukinetic trends were induced by balanced promedol analgesia throughout the operation. Concentrations of hydrocortisone, aldosterone and STH were on the increase, while T3 and T4 levels lowered. Hyperkinetic and eukinetic hemodynamics were observed postoperatively after neuroleptanalgesia and balanced promedol-including analgesia, respectively.
