A comparison of the influence of 2.7% sorbitol-0.54% mannitol and 5% glucose irrigating fluids on plasma serum physiology during hysteroscopic procedures.

Background: 2.7% sorbitol-0.54% mannitol has been selected as an alternative irrigating fluid during endoscopic surgery for its theoretical advantages. We compared the influence of 2.7% sorbitol-0.54% mannitol (Urosol™, CJ Pharma, Seoul, Korea) and 5% glucose as an irrigating solution for hysteroscopic myomectomy & polypectomy in the occurrence of associated complications.

Methods: Thirty patients scheduled for a hysteroscopic operation were included in a prospective randomized trial comparing 2.7% sorbitol-0.54% mannitol solution (Group S, n = 15) and 5% glucose (Group G, n = 15) as an irrigating fluid. We recorded the amount of the irrigating fluids, the amount of fluid intake, and the duration of the procedure. Serum sodium, chloride, potassium, glucose values, and serum osmolality were measured before (just after the induction, T1), during (when 2 L of irrigation fluid was infused, T2), and after (1 h after the end of the operation, T3) the hysteroscopic procedure.

Results: The mean volume of absorbed irrigating fluid was 185.0 ± 73.5 ml in Group G and 175.4 ± 50.5 ml in Group S. Transient hyperglycemia occurred in one patient of Group G. No differences were found in the intraoperative and postoperative levels of serum sodium, potassium, chloride, glucose and osmolality in both groups.

Conclusions: There was no clinical evidence of hyponatremic hypoosmolality in any of the patients. We found no difference between 2.7% sorbitol-0.54% mannitol and 5% glucose as an irrigating fluid for hysteroscopic procedures with mild to moderate irrigant absorption.
