Background: Laparoscopic examination is a useful investigation in the evaluation of infertile women. To perform this test, pneumoperitoneum is required to distend the abdomen, improve visibility and displace the intestines out of the pelvis. Several gases have been used to achieve this purpose including Nitrous Oxide (N2O), Carbondioxide (CO2), Helium, Xenon and Air. Study Design and Method: This was a prospective study in a private fertility centre in Nnewi, Nigeria aimed at reducing the morbidities inherent in the use Room Air pneumoperitoneum for diagnostic laparoscopy. This was sequel to an earlier study, which revealed that women who had Room Air pneumoperitoneum had a higher port wound infection rate, abdominal discomfort (feeling of retained gas in the abdomen) and shoulder pain with resultant delayed return to normal activity than women who had Co2 pneumoperitoneum. Results: This study demonstrated that the use of soda lime to purify the Room Air and a low pressure suction pump to evacuate the air after the procedure significantly reduced the wound infection rate and virtually eliminated the abdominal discomfort and shoulder pain associated with Room Air pneumoperitoneum. This was followed by early return to normal activity. Conclusion: Therefore, use of Room Air for pneumoperitoneum is safe and affordable. It is recommended for low resource settings.
