Death during hysteroscopy under general anesthesia

Many people are very scared when undergoing hysteroscopy, always worrying that the operation has certain risks and even the chance of death. But in fact, hysteroscopy is not as scary as everyone imagines. It is a relatively safe surgical method. However, before the operation, you must do a good check-up to ensure that your body is in absolute health to make the operation go more smoothly.

Before the operation, the perfusion system is started to expand the uterus. This can ensure the intrauterine pressure and also have the effect of cooling and flushing. Hysteroscopy is divided into inspection hysteroscopy and surgical hysteroscopy. There are three different types of electrodes in surgical hysteroscopes, and their normal operation depends on the support of the energy system, that is, electric current. In addition, in order to ensure the accuracy of the operation, a light source system and an imaging system are also needed to help. During the operation, clear lighting and monitoring of the imaging system can avoid unclear vision and play a guiding role.

Bleeding

There is usually a small amount of vaginal bleeding after hysteroscopy, which usually stops within a week. Hysteroscopic surgery may cause excessive bleeding due to excessive cutting, poor uterine contractions, or incomplete hemostasis during the operation. Bleeding can be stopped with an electrocoagulator or by compression with a Foley catheter for 6 to 8 hours.

Infect

The infection rate is low. Knowing the indications and contraindications, using antibiotics appropriately before and after surgery, and strictly disinfecting instruments can avoid the occurrence of infection.

Complications of uterine distension

Excessive absorption of distending fluid is a common complication during uterine distension, which often occurs during hysteroscopic surgery and is related to excessive distension pressure and a large area of ​​endometrial damage. The pressure during uterine distension can be maintained at 100 mmHg (13.3 kPa). Excessive pressure is not conducive to clear vision, but instead causes fluid to flow into the abdominal cavity through the veins or fallopian tubes and be absorbed in large quantities.

If the operation lasts too long, it may easily lead to excessive absorption, resulting in excessive blood volume and hyponatremia, causing a series of systemic symptoms, and in severe cases, death. Using carbon dioxide as a uterine inflation medium can lead to serious complications or even death if the inflation speed is too fast. Currently, a dedicated inflation device is used, and the inflation speed is controlled at 100ml/min to avoid the occurrence of complications. Carbon dioxide uterine distension causes postoperative shoulder pain, which is caused by carbon dioxide stimulating the diaphragm.
