Özet

Amaç: Bu çalışmanın amacı, supin pozisyonda alt ekstremite cerrahisi geçiren hastalarda, spinal anestezinin göz içi basıncı (GİB) üzerine etkisinin değerlendirilmesidir. Gereç ve Yöntem: Spinal anestezi uygulamasından önce ve 20 dk sonra tüm hastaların GİB’leri Tono-pen XL ile ölçüldü. Kan ba- sıncı, periferik oksijen satürasyonu ve elektrokardiyografi monitörizasyonu, spinal anesteziden önce başlatıldı ve cerrahi boyunca her 5 dk’da bir tekrarlandı. GİB ölçümüyle eş zamanlı olarak ölçülen ortalama sistemik arteriyel basınç değerleri not edildi. GİB ve ortalama arteriyel basınçtaki değişiklikler t testi ile karşılaştırıldı. Bulgular: Çalışmaya 49 hastanın 98 gözü dahil edildi. Anestezi öncesi ortalama GİB 18.6±2.8 mmHg iken spinal anestezi uygu- lamasından 20 dk sonra 15.7±2.9 mmHg olarak ölçüldü (p<0.05). Anestezi öncesi ortalama sistemik arteriyel basınç 109.5±16.8 mmHg iken, anesteziden 20 dk sonra 91.6±15.3 mmHg olarak ölçüldü (p<0.05). Sonuç: Spinal anestezi supin pozisyonda göz içi basıncında anlamlı düşüşe neden olmaktadır. Spinal anestezinin hipotansiyon yan etkisinin bu düşüşte rolü olabilir.

Abstract

Purpose: The aim of this study was to evaluate the acute effect of spinal anesthesia on intraocular pressure (IOP) in supine posi- tioned patients underwent lower extremity surgery. Materials and Methods: IOP was measured in all patients with Tono-Pen XL before and 20 minutes after spinal anesthesia appli- cation. Monitorization of blood pressure, peripheral oxygen saturation and electrocardiogram was initiated before spinal anesthesia and repeated at every 5 minutes during surgery and mean systemic arterial pressure measurement was recorded at the same time with IOP measurement. IOP and mean arterial pressure changes were evaluated with t test. Results: There were ninety-eight eyes of 49 patients. The mean intraocular pressure was 18.6±2.8 mmHg before anesthesia. Twenty minutes after spinal anesthesia application, the mean IOP was reduced to 15.7±2.9 mmHg (p<0.05). The mean systemic arterial pressure was 109.5±16.8 mmHg before anesthesia. Twenty minutes after, the mean systemic arterial pressure was mea- sured as 91.6±15.3 mmHg (p<0.05). Conclusion: Spinal anesthesia seems to significantly decrease intraocular pressure in patients under supine positioned. Hypoten- sion side-effect may have a role in this decrease.
