Randomized Controlled Trial
[Lavasept as an alternative to PVP-iodine as a preoperative antiseptic in ophthalmic surgery. Randomized, controlled, prospective double-blind trial].
To reduce the risk of endophthalmitis PVP-iodine is typically used preoperatively. Since iodine is contraindicated in patients with a specific allergic history or severe thyroid disorder we studied the effect of Lavasept, which contains Polyhexanid as an antiseptic alternative. ⋯ The use af Lavasept is safe, well tolerated and reduces the microbiological contamination of the conjunctival fornix effectively. lt provides a more effective reduction of the cfu's than PVP-iodine 1.25% and this effect tends to be prolonged. Lavasept is a good alternative option in ophthalmology for preoperative antisepsis.

Randomized Controlled Trial Clinical Trial
[Assessment of anesthesia methods in ophthalmologic surgery by patients, surgeons, and anesthesiologists].
The purpose of this study was to evaluate anesthesia methods in ophthalmic surgery in elderly people assessed by patients, surgeon, and anesthesiologist using subjective rating scales. ⋯ In this study patients and anesthesiologists preferred TIVA. There was no difference between TIVA and BA as seen by the surgeon.

Randomized Controlled Trial Clinical Trial
[Additive retrobulbar anesthesia in surgery of retinal detachment with general anesthesia. Reduced postoperative pain and stress response].
It has recently been shown that the pain occurring after retinal detachment surgery can be reduced by combined general and retrobulbar anesthesia. This study investigated the effect of retrobulbar anesthesia on the intra- and postoperative stress response and on postoperative pain, vigilance, nausea and vomiting. ⋯ The data show that combined local and general anesthesia has several advantages over general anesthesia alone, especially when the retrobulbar injection is given before retinal detachment surgery.

Randomized Controlled Trial Clinical Trial
[Perioperative follow-up of physiologic and cognitive functions after oral premedication with midazolam 3.75 mg in women for retrobulbar anesthesia].
Recent changes in the medical system have resulted in a significant increase in the number of surgical procedures performed as day surgery. Therefore, a safe and short postoperative recovery period has become increasingly important. In the present study we investigated perioperative cognitive and physiological functions after oral premedication with low-dose midazolam (3.75 mg). ⋯ No differences between the groups could be found 2 h after the operations (2.92 +/- 35 min after premedication). Intraoperatively there was no significant difference in end-tital PCO2 and oxygenation between the groups. Oral administration of low-dose midazolam (3.75 mg) seems to be an appropriate form of premedication for ambulatory surgical procedures in elderly patients.

Randomized Controlled Trial Comparative Study Clinical Trial
[Motor blockade by retrobulbar anesthesia. Phenomenology and mechanism of action].
The aim of this study was to analyze quantitatively the phenomenology and mechanisms of motor blockade induced by retrobulbar anesthesia (RETRO). ⋯ The present findings may be interpreted as temporary palsy of N.III and N.VI during RETRO (symmetrical blockade of horizontal and vertical recti eye muscles) with unaffected function of N.IV and superior oblique muscle (maintained incycloduction ability; hypotropia and exotropia). An additional possible mechanism to account for the observed downward deviation is that the eye assumes its physiological divergent resting position during RETRO.
