Abstract
Background: Due to its numerous benefits laparoscopic surgery become very popular
among physicians, hospitals and patients nowadays. In the urologic pathology laparoscopy can
be performed with retroperitoneal or transperitoneal approach. Insufflation of CO2 for achieving
visibility in both of the approaches can be absorbed in the vessels and can lead to alterations in
arterial blood gasses.
Material and Method: Study population was elective urologic patients scheduled for laparoscopic surgery. Investigated arterial blood gas variables were determined in three time points: T0
before induction – basal, T1 after one hour of CO2 insufflation, and T2
at the end of the surgery.
Results: Alterations in arterial blood gasses were seen in T1 and T2 for PaO2 in retroperitoneal vs transperitoneal group 173.3 ± 19 vs 196.6 ± 29 (p < 0.003) and 95.5 ± 5.4 vs 101.1 ±
8.2 (p < 0.001). The PaCO2 was also statistically significant in second observed time point T1 in
retroperitoneal vs transperitoneal group 45.9 ± 4.1 vs 38.2 ± 0.3 (p < 0.002).
Conclusion: The findings that we have presented can suggest that both approaches are safe
although hypercarbia is observed in retroperitoneal group.
