During a hysteroscopy for myomectomy excision, which vital aspect should be monitored to prevent extreme swelling?

In the context of a hysteroscopy for myomectomy excision, monitoring fluid intake and output is critical to prevent extreme swelling, which can occur due to the absorption of liquid into the systemic circulation. During this procedure, distension of the uterine cavity is typically achieved using a fluid, and if the fluid volume is not carefully controlled and monitored, it can lead to complications such as fluid overload or hyponatremia.

Excess fluid absorption can lead to an increase in intra-abdominal pressure and result in swelling and edema, particularly in tissues surrounding the surgical site. Thus, accurate measurement of fluid that is instilled and the amount that is suctioned or drained out is essential. This monitoring helps the surgical team to manage fluid balance effectively and intervene promptly if excessive fluid absorption is suspected.

While monitoring heart rate, blood pressure, and body temperature are also important for overall patient safety and can provide insights into the patient's stability and response to the surgery, they do not specifically address the risk of fluid overload and its resultant swelling, making fluid intake and output monitoring the most critical aspect in this scenario.
