A Prospective Study to Analyse Safety of Low Flow Anesthesia for Laparoscopic Procedures
Journal Title: International Journal of Current Research and Review - Year 2017, Vol 9, Issue 6
Abstract
Background: Anesthesia for laparoscopic surgery has developed and advanced significantly, resulting in a technique that is safe and provides better outcome than before. Low flow anesthesia is newer technique which is more economic, ecofriendly and effective. But there is reluctance in combining these two techniques due to risk of hypoxia and hypercapnia. So, this study was conducted to prove that low flow anesthesia is safe in laparoscopic surgeries. Method: A prospective observational study including 70 patients (ASA I/II, 18-65 years) undergoing various laparoscopic procedures was conducted with the permission of institutional ethical committee and patient’s consent. Selected patients were assigned into two groups with fresh gas flow 3L and 0.5L in high and low flow group respectively. The inspiratory and expiratory concentrations of various gases were compared. Also, the increase in soda lime temperature and change in liver/kidney functions were studied. Result: Demographic data in both the groups were comparable. Inspiratory and expiratory concentration of oxygen, carbon dioxide and sevoflurane were comparable at all intervals of time without any complication. Temperature of sodalime increased in both the groups, but was comparable. Also, there was no significant change in postoperative liver/kidney function tests. Conclusion: Low flow technique is a safe, efficient technique of general anesthesia for laparoscopic surgery.
