Summary
This study introduces a simple method to estimate blood loss during laparoscopic myomectomy by measuring hemoglobin in waste fluid. The HemoCue device provides quick and reliable results, aligning with surgeon experience.
Area of Science:
- Gynecology
- Surgical Innovation
- Medical Diagnostics
Background:
- Accurate blood loss estimation during laparoscopic myomectomy is challenging due to irrigation fluid use.
- Existing methods may be subjective or time-consuming.
Purpose of the Study:
- To develop and validate a novel, objective method for estimating blood loss during laparoscopic myomectomy.
- To assess the utility of the HemoCue device for this purpose.
Main Methods:
- Measuring hemoglobin concentration in waste irrigation fluid using HemoCue.
- Calculating estimated blood loss with a derived formula: Estimated blood loss (ml) = [waste irrigation fluid volume (ml)]x[Hb concentration in waste irrigation fluid (g/l)]/[patient's preoperative Hb level (g/l)].
- Comparing estimated blood loss with subjective surgeon assessment.
Main Results:
- The HemoCue method provided blood loss estimations ranging from 17.6 to 725.2 ml in 23 patients.
- The HemoCue device requires minimal sample volume (10 μl) and delivers results rapidly (45 seconds).
- The developed method showed accordance with the surgeon's subjective estimation of blood loss.
Conclusions:
- This hemoglobin-based method using HemoCue offers a quick, easy, and reliable approach to estimate blood loss during laparoscopic myomectomy.
- The findings suggest this technique can supplement subjective assessments, improving surgical safety and data accuracy.
