Summary

infromedial injection of 3 ml local anesthetic drugs and assessing the pain during lacrimal duct intubation and probability of false tracking

Detailed description

After entering the OR; the patient will be cannulated and fully monitored with basic monitors (pulse oximeter, NIBP \& ECG), a nasal cannula is connected to the patient to deliver oxygen. We gave the patient 5 ml of propofol to decrease the discomfort felt by the patient during injection of local anesthesia. Benox eye drops is applied to the operative eye in both groups. Patients were allocated into 2 groups; each group is 25 patients Group 1: We used a 25G/ 1" length needle to inject 3ml of lidocaine: bupivacaine (1:1) with 30 IU hyaluronic acid, 0.5ml below the inferior punctum in the lower lid medial margin. Group 2: We used a 25G/ 1" length needle to inject 3ml of lidocaine: bupivacaine (1:1) with 30 IU hyaluronic acid classical medial canthal injection During surgery, we will assess the pain degree during probing using Verbal Rating Scale (0 to 10 scale where 0 is no pain an 10 is unbearable pain), to assess the efficiency of this single low volume injection.
