rocuronium and Glaucoma--Angle-Closure

Acute angle-closure glaucoma (AACG) is a rare complication of general anesthesia. The coexistence of individual risk factors for postoperative AACG and factors associated with intraocular hypertension are considered to be required for postoperative AACG to develop. We present a case of AACG after general anesthesia for oral bone grafting in a patient with no preoperative eye symptoms. In this case, several factors such as postoperative care in a darkened room, psychological stress, and postoperative hypertension may have precipitated the event in this patient, who may have had preexisting undiagnosed elevated intraocular pressure. The interval between the earliest appearance of symptoms at 9 hours and the ultimate diagnosis was 36 hours. In the postoperative period following general anesthesia, any patient is at risk for AACG. It is important that a postoperative diagnosis of AACG should be considered and a timely consultation with an ophthalmologist be considered if a postoperative patient complains of red eyes, visual disorder, eye pain, headache, and nausea.

An 86-year-old woman was scheduled to receive fourth reconstructive surgery for femoral bone fracture under general anesthesia. She had been suspected with narrow angle glaucoma due to headache and bloodshot eyes during gastroscopy. During transfer to our hospital, she fell down and suffered from the right femoral neck fracture. The patient underwent femoral head replacement under spinal anesthesia. Later, she received surgeries twice uneventfully under spinal anesthesia; removal and re-implantation of the femoral bone head due to infection of the implanted head. Six months later, she fell down again and femoral bone was fractured during rehabilitation. Anesthesia was induced with propofol followed by rocuronium 0.9 mg x kg(-1) i.v. Anesthesia was maintained with propofol and remifentanil, and rocuronium was administered to maintain PTC of 10 or less. The surgery was completed in 150 minutes. At the end of surgery, a laryngeal mask was inserted and the tracheal tube was removed. TOF ratio recovered to 80% 8 minutes after sugammadex 2 mg kg(-1) i.v., and increased to 100% 3 minutes after additional 1 mg x kg(-1). Intraocular pressure stayed below 20 mmHg during the intervention. We could achieve full reversal of neuromuscular blockade and suppress increase in intraocular pressure with use of sugammadex.
