Anaesthesia characteristics
| Variables | Experimental group (n=63) | Control group (n=65) | P value |
| Topical anaesthesia, n (%) | 63 (100.0) | 65 (100.0) | >0.99* |
| Oral anxiolytic presurgery, n (%) | 0 (0.0) | 2 (3.1) | 0.50* |
| Intracameral injection of xylocaine, n (%) | 19 (30.2) | 22 (33.8) | 0.65† |
| Intravenous sedation, n (%) | 56 (88.9) | 55 (84.6) | 0.48† |
| If intravenous sedation, compliance with recommended protocol, n (%‡) | 55 (98.2*) | 55 (100.0*) | 0.60* |
| Anaesthetist called for supplementary sedation, n (%) | 3 (4.8) | 6 (9.2) | 0.49* |
*P values were calculated using Fisher’s exact test.
†P values were calculated using χ2 test.
‡Percentage of patients with intravenous sedation who complied with the protocol.
