Anesthesia for hysteroscopy.

Hysteroscopy is becoming a more widely used technique. Diagnostic hysteroscopy is replacing conventional dilatation and curettage in the diagnosis of intrauterine pathologies. Transcervical endometrial resection is often the first-line surgical treatment for dysfunctional uterine bleeding and carries less associated morbidity and morality. Overall, the technique is extremely safe, but vigilance is required particularly for intravasation of irrigation media. Complications such as gas embolus and hypo-osmolar hyponatremia require prompt treatment to reduce associated morbidity and morality. Careful monitoring of fluid deficit is paramount in avoiding the latter problem. Regional or general anesthetic techniques can be used and, in the ambulatory or office-based setting, in which these procedures are increasingly performed, the need for "street readiness" can influence the choice of the agents used.
