Why the study?
Does carbon dioxide insufflation compared to nitrous oxide increase the incidence of cardiac arrhythmias during laparoscopy?
Population
145 patients undergoing laparoscopy
Comparison
Carbon dioxide insufflation to inflate the abdomen vs Nitrous oxide insufflation
Design
Cohort
Follow-up
Intraoperative (during laparoscopy)

Carbon dioxide insufflation was associated with more arrhythmias; leaves open causal inference and requires randomized confirmation.
Does carbon dioxide insufflation compared to nitrous oxide increase the incidence of cardiac arrhythmias during laparoscopy?
Carbon dioxide insufflation during laparoscopy is associated with a higher incidence of cardiac arrhythmias, higher PaCO2, and lower pH compared to nitrous oxide.
Scott et al. (1972) studied this question.
