Laparoscopic surgery: does it increase the probability of atrial and ventricular arrhythmias in children?

Area of Science:

• Pediatric Surgery
• Cardiology
• Anesthesiology

Background:

• Laparoscopic procedures involve insufflating carbon dioxide (CO2) for pneumoperitoneum, potentially affecting cardiac electrophysiology.
• Electrocardiographic (ECG) alterations during pneumoperitoneum may indicate a risk for arrhythmias.
• QT dispersion (QTD) and P wave dispersion (PWD) are markers of cardiac electrical heterogeneity.

Purpose of the Study:

• To evaluate changes in QTD and PWD in children undergoing laparoscopic appendectomy.
• To assess the impact of CO2 pneumoperitoneum on cardiac electrical variables in pediatric patients.

Main Methods:

• Sixteen pediatric patients with appendicitis underwent laparoscopic appendectomy.
• ECG recordings were taken before insufflation (ECG1), after insufflation (ECG2), before desufflation (ECG3), and after desufflation (ECG4).
• QTD and PWD were analyzed from ECGs recorded at 25 mm/s.

Main Results:

• Mean corrected QTD and PWD were significantly elevated at ECG2 and ECG3 (post-insufflation) compared to ECG1 and ECG4 (pre- and post-desufflation).
• The observed increases in QTD and PWD induced by CO2 insufflation were reversible.
• No significant long-term electrophysiological changes were indicated by the reversible nature of the findings.

Conclusions:

• Pneumoperitoneum during laparoscopic appendectomy in children leads to transient increases in QTD and PWD.
• The clinical implications of these reversible ECG changes in pediatric patients warrant further research.
• Further studies are needed to determine the clinical significance of pneumoperitoneum-induced electrophysiological alterations in children.
