Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative ketorolac and eye pain after viteoretinal surgery: a prospective, randomized, placebo-controlled study.
To compare the efficacy of one intraoperative dose of intravenous ketorolac tromethamine to saline placebo in controlling postoperative eye pain, nausea, and sedation following vitreoretinal surgery. ⋯ Ketorolac tromethamine is an effective nonnarcotic choice for postoperative pain control following vitreoretinal surgery. Pain control is particularly important in this group of patients, whose compliance with postoperative procedures and positioning may significantly affect surgical outcome.

To assess the cost savings that would result from 1) implementing the treatment guidelines of the Endophthalmitis Vitrectomy Study (EVS) and 2) performing procedures on an outpatient rather than an inpatient basis, and to compare the savings to the cost of conducting the EVS. ⋯ Implementing the treatment guidelines of the EVS on an outpatient basis may result in significant cost savings--savings that may cover the entire cost of the EVS in 3 years.

Case Reports
Complications of general anesthesia using nitrous oxide in eyes with preexisting gas bubbles.
To present the visual and anatomical outcomes for patients with intraocular gas placed during vitreoretinal surgery who subsequently underwent surgery wherein general anesthesia with nitrous oxide was used. ⋯ The use of nitrous oxide during general anesthesia in gas-filled eyes may have disastrous visual results caused by gas expansion and elevated intraocular pressure. Patients must be advised of the potentially catastrophic results of undergoing general anesthesia before their intraocular gas bubble has resorbed. The use of nitrous oxide for patients with intraocular gas should be avoided. It may be prudent for patients with intraocular gas to wear notification bracelets warning anesthesiologists about the presence of intraocular gas lest emergency surgery be needed by a patient unable to advise anesthesia personnel about the potential danger.

Randomized Controlled Trial Comparative Study Clinical Trial
Preemptive analgesia in rhegmatogenous retinal detachment surgery: is it effective?
To evaluate the efficacy of preemptive analgesia in surgical repair of retinal detachment (RD) using scleral buckle and cryopexy under general anesthesia. ⋯ The use of sub-Tenon block as preemptive analgesia after induction of general anesthesia and before the start of rhegmatogenous RD surgical repair was effective in reducing postoperative pain and analgesic requirements compared with an unblocked group. The use of sub-Tenon block was also effective in reducing intraoperative incidence of oculocardiac reflex and postoperative incidence of vomiting.

To assess the existence of any correlation between the quantity of silicone oil emulsified in the anterior chamber and the incidence of high intraocular pressure in vitrectomized eyes. ⋯ This study showed a high correlation between the incidence of high intraocular pressure and the quantity of emulsified silicone oil in the anterior chamber.
