The effect of anterior chamber lidocaine injection on pain reduction after cataract surgery under general anesthesia

Postoperative pain is an acute pain, and treatment is reduce morbidity. Cataract is the most common cause of blindness in developed countries and the only effective treatment is surgery. Because the eye is a sensitive organ and most patients are elderly and with low pain threshold, therefore, it is important to reduce the pain caused by cataract surgery.
The study included 48 male and female patients with an age range of 20 to 80 years and ASA1 & 2. Patients were divided randomly to two groups of 24 person, each of the 2 groups were under general anesthesia with equal drugs, in the study group 0/1 cc lidocaine1% intra cameral was injected after anesthesia and the control groups did not receive it. Patients were assessed before surgery and recovery (time zero), 1, 2 and 3 hours after surgery in terms of pain, blood pressure, heart rate and effects such as itching.
The study group had lower pain than the control group, but blood pressure and heart rate were not significantly different between the 2 groups.
