Insights
Video-assisted thoracic surgery in children is safe and effective, causing minor respiratory, circulatory, and temperature changes. Factors like lung exclusion and procedure length can influence these physiological responses during thoracoscopy.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Anesthesiology
Background:
- Video-assisted thoracic surgery (VATS) is increasingly utilized in pediatric diagnostics and therapeutics.
- Understanding physiological changes during VATS in children is crucial for safe practice.
Purpose of the Study:
- To assess respiratory, cardiocirculatory, and body temperature changes during pediatric thoracoscopy.
- To identify modifiable factors influencing these physiological trends, including lung exclusion, procedure duration, and preoperative respiratory status.
Main Methods:
- Analysis of 50 pediatric patients undergoing general anesthesia for diagnostic/therapeutic thoracoscopic procedures.
- Monitoring of key parameters at six time points: pre-induction, post-positioning, pre-insufflation, during insufflation, pre-deflation, and post-deflation.
- Comparison of physiological data under different ventilation strategies (one-lung vs. two-lung) and insufflation conditions.
Main Results:
- Thoracoscopy was well-tolerated with no intraoperative complications.
- Significant reductions in systolic and diastolic blood pressure and body temperature were observed.
- Elevated end-tidal CO2 levels were noted during the procedure, influenced by lung exclusion, procedure length, and preoperative respiratory compromise.
Conclusions:
- Pediatric thoracoscopy induces predictable physiological changes.
- Despite these changes, the technique is deemed safe and effective for pediatric patients.
- Monitoring and understanding these changes are vital for optimizing patient management during thoracoscopic procedures.
Aim:
Videoassisted thoracic surgical technique in children is being used with increasing frequency for an extensive variety of diagnostic and therapeutic procedures. The aim of the study was to assess respiratory, cardiocirculatory and body temperature changes in children undergoing thoracoscopy and to identify if the trend of such changes was modifiable by factors such as lung exclusion, length of the thoracoscopy and preoperative respiratory compromise.
Methods:
A total of 50 patients (38 boys and 12 girls) undergoing general anaesthesia for diagnostic and therapeutic thoracoscopic procedures were analysed. The values of the monitored parameters were compared at 6 specific times: T1 - at the end of anaesthesia induction (considered the basal level); T2 - after lateral position; T3 - before pleural CO2 insufflation; T4 - 10 min after pleural CO2 insufflation; T5 - before pleural deflation; T6 - 10 min after pleural deflation.
Results:
All patients tolerated the thoracoscopy well, without intraoperative complications. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly lower, and end-tidal CO2 (PETCO(2) significantly higher during thoracoscopy. Body temperature (BT) had a statistically significant reduction during thoracoscopy and after pleural deflation. During one-lung ventilation the PETCO(2) increased compared to two-lung ventilation with intrapleural insufflation, while during two-lung ventilation with intrapleural insufflation SBP and DBP decreased compared to one-lung ventilation. The length of the thoracoscopy increased the PETCO(2) and reduced the BT. The preoperative respiratory compromise increased the PETCO(2).
Conclusions:
Although thoracoscopy in children brings about certain respiratory, cardiocirculatory and body temperature changes, it is nevertheless a safe and efficient surgical technique.
