Status: Recruiting
Location: See location...
Intervention Type: Device
Study Type: Interventional
Study Phase: Not Applicable

The objective of this prospective, randomized controlled study was to evaluate the effectiveness of this NCH gel in the prevention of IUA development as assessed by hysteroscopy after USG-MVA, in the treatment for first-trimester miscarriage. To study the severity and extent of the IUA as assessed by the AFS and ESGE adhesion score in both groups of patients. To examine the rate of complications or side effects with the NCH gel. To assess the subsequent menstrual history and reproductive outcome in both groups of patients.

Experimental: Intervention group (Group A): NCH gel after USG-MVA
In the intervention group (Group A), a 15 cm sterile delivery cannula will be inserted through the internal os and a syringe of NCH gel (5ml) will be applied to the uterine cavity after cleansing the cervix with an antiseptic solution.
