Secondary to the distension gaseous

N2O (nitrous oxide) - lung clot, bradycardia and collapse.

CO2 (carbon dioxide) - pain in the area of the scapula bone, due to the estimulation of the frenic nerve, that disappears spontaneously after some minutes. Hypercapnia, acidosis, arrhythmia and cardiac arrest are not more found now with the amount and pressure of the gas used, being recommended a maximum flow of 100 ml/min and a maximum pressure of 150 mmHg.

Secondary to the distension liquid

Overload - excessive passage of liquid to the current blood, causing dilution, hyponatremia, arterial hypertension and pulmonary edema, in the postoperative it can cause hipotension and mental confusion. It happens mainly when the operative procedure is long, high pressure of distention, depth of the miometrium dried up above 4 mm and in the luteal phase of the menstrual cycle for the largest vascularization of the endometrium.

Anaphylaxis (solution of Hyskon).

Encephalopathy (glicina).

Hyperglycemia (glucose and sorbitol).

Hemolition (distilled water).

Air embolism.

Infectious (average of 7 in 1000 interventions, being rare in the diagnostic).

Endometritis

Salpingitis

Pelvic inflammatory disease.

Traumatic

Cervical trauma (laceration by Pozzi or during the dilation).

Uterine trauma (perforation, more frequently happening in the surgical intervention).

Intestinal trauma, vesical trauma, ureter and great vases trauma (direct or indirect, being this caused by eletrocoagulation).

Hemorragics  (intra and postoperative).

Synechiae

Hematometra, criptomenorrhea and recurrent pain  (it happens mainly in the total ablation of the endometrium).

Pregnancy  (it has been told cases of pregnancy after ablation of the endometrium, causing abnormal placental insert and retarded intra-uterine growth).

Uterine malignancy (there is a potential risk of malign alteration in an area of occult endometrium after ablation of the endometrium).

Painful  (the anxious patients, never pregnancy and postmenopausal are more susceptible to the painful sensation in the diagnostic intervention, being therefore suitable a mitigation or analgesia).

Reaction vagal.

Bradycardia.

Sensorial alterations.

Syncope.

Cardiac arrest.

Anesthetic

Allergic reactions.

Heart arrhythmia.

Convulsions.

Flaws therapeutics (in the cases of ablation of the endometrium they are about from 10 to 20%, independently of the technique).

The non accomplishment of the intervention, due to cervical stenose or significant bleeding.

After the surgical intervention a vaginal secretion for 2 to 4 weeks is frequent and unscent.

The diagnostic intervention is extremely safe. The surgical intervention associates to more complications due to use of distension liquid, of sharp instruments, of the electric current, of the laser and of the anesthesia.
