Anaesthetic considerations for hysteroscopic surgery

Area of Science:

• Gynecology
• Minimally Invasive Surgery
• Anesthesiology

Background:

• Operative hysteroscopy (OH) is a key tool for intrauterine disease and an alternative to hysterectomy for menorrhagia.
• OH offers advantages like short operating time, quick recovery, and low morbidity.
• Potential serious complications during and after OH require awareness among surgical and anesthesia teams.

Purpose of the Study:

• To highlight the potential serious complications of operative hysteroscopy (OH).
• To emphasize the importance of awareness and early detection of complications for patient safety.
• To discuss anesthetic techniques and patient positioning to mitigate risks.

Main Methods:

• Review of complications associated with endoscopic surgery, drawing parallels with urological procedures like transurethral resection of the prostate (TURP).
• Discussion of specific OH complications: fluid overload, hyponatraemia, hypo-osmolality, hemorrhage, uterine perforation, and embolism.
• Consideration of anesthetic techniques and patient positioning to prevent adverse events.

Main Results:

• Fluid overload with hyponatraemia and hypo-osmolality can occur in up to 6% of OH cases and may be fatal.
• Regional anesthesia may allow for earlier detection of fluid overload compared to general anesthesia.
• Careful patient positioning is necessary to prevent peripheral neuropathy.

Conclusions:

• Preventing, detecting, and treating complications like fluid overload are paramount in operative hysteroscopy.
• Anesthesia choice and meticulous surgical technique are critical for minimizing OH risks.
• Further research comparing anesthetic techniques for OH is warranted.
