What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
sedation with subtenon injection of local anestheticProcedure or surgery
sedation was induced with fentanyl a loading dose of propofol, followed by continuous infusion of propofol, 3-6 mg/k/h to deep sedation. A nasal tube was inserted to prevent airway obstruction. SubTenon's anaesthesia included "standard" solution is a mixture of 2% plain lignocaine, 0.5% plain bupivacaine, and 150 iu hyaluronidase 0.5%.
General Anesthesia (control group)Procedure or surgery
General anaesthesia consisted of premedication with midazolam, followed by fentanyl, cis atracrium, propofol, and tracheal intubation
| Study group | Role | What they receive |
|---|---|---|
| study group : subtenon injection of local anesthetic with propofol sedation | Active comparator | Not described Receives: Procedure: sedation with subtenon injection of local anesthetic |
| controle group : patient receive general anesthesia | Active comparator | Not described Receives: Procedure: General Anesthesia (control group) |
What is being measured
The primary outcome is the main question the study is designed to answer.
patient satisfaction in combined propofol/sub-Tenon's anaesthesia in unilateral or bilateral strabismus surgery according to scale from 1 to 10 a one not satisfied and 10 completely satisfied
Measured: 12 hour after the end of the operation
