Introduction: Hysteroscopy is used increasingly for assessment and treatment of uterine disorders. However, the application of new technology mandates the study of the related complications of the procedure .The aim of this study is evaluation of Na and Hgb changes due to hypotonic disturbance and bleeding following hysteroscopy and their correlation with duration of procedure.
Methods: This cross-sectional study enrolled 100 women in ASA 1 and ASA 2 class (American Society of Anesthesiologists) in the age range of 17-50 years old who were candidate of hysteroscopy in Imam Khomeini hospital of Ahwaz in a one year period.(from September2007 to September 2008) .Random sampling was done. After primary clinical evaluation that included serum Na and Hgb, patients were anesthetized by a classic method and hysteroscopy was done by a single expert surgeon. Glycin 1.5% was used for uterine dilatation. Serum Na soon after surgery and Hgb 4-6 hours after surgery were rechecked. Duration of surgery, vital signs and the presence of nausea and vomiting were recorded in recovery room. Then data were analyzed by Spss software (13 versions) and analyzed by t test and chi- square test. P value of 0.05 was considered significant.
Results: Abnormal uterine bleeding and infertility were the most common causes of admission of patients. No patient had allergy to glycin as uterine dilator. The mean serum sodium before surgery was 137. 48±7.2 meq/dl and it was 137±6.2 meq/dl (p>0.05) after operation. The average of Hgb before surgery was 11.007±1.2 gr/dl and mean Hgb was 10.97±1.1gr/dl after operation. There was no relationship between duration of the operation and change in the level of sodium and Hemoglobin. The procedure lasted 45±5.5 minutes on average. No nausea and vomiting was observed in the recovery room
Conclusion: Hysteroscopy doesn’t cause any problems due to the decreased serum sodium and hemoglobin concentration within 45 minutes of the procedure. It can be regarded as a safe and effective procedure in diagnosis and treatment of common uterine diseases especially uterine bleedings and symptomatic benign uterine diseases.
