Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The expected primary endpoint for the study was to increase the safety and efficacy of periconal anesthesia with ultrasound guidance, as well as the improvement of needle placement accuracy when compared to the conventional blind technique, on the occurrence of complications. The real placement of the needle in orbit cavity was evaluated by measuring the length of the needle, the distance between the needle tip and the optic nerve as well as the insertion depth of the needle in relation to the iris plane, in ultrasound images. | — |
Secondary
| Measure | Time frame |
|---|---|
| Point out if it existed superiority of one technique over another, explaining the advantages and disadvantages of the use of ultrasound in relation to the usual technique, besides demonstrating if the ultrasound technique proposed was easily performed through the time required for its completion.;Real-time visualization of the needle reduced the chance of having unintentional intraconal block and the placement of the needle inadvertently close to the optic nerve. Thus, Real-Time Ultrasound-Guided Periconal Blockade proved to be safe and equally effective as the Conventional Periconal Blockade Technique, in patients with normal eyes. | — |
