Abstract

We aimed to investigate the effects of midazolam and sevoflurane on oculocardiac reflex (OCR), which is a major problem in strabismus surgery.After taking the Hospital Ethics Committee approval and informed consent from the parents, 40 ASA I patients, 1-7 years old, scheduled for elective unilateral strabismus surgery were included in the study. All patients were given atropine and midazolam perorally for premedication. Patients were randomly allocated into two groups; Group S, was given sevoflurane, Group M was given midazolam. In Group S, anesthesia was induced with by sevoflurane 8 % in O2 40 % and N2O 60 %, via face mask and sevoflurane was reduced to 2 % for maintenance . Whereas in Group M, anaesthesia was induced with 0.5-1 mg kg-1 and maintained with midazolam at an infusion rate of 4 µgr kg min-1 supplemented by O2 40 %, N2O 60 %. Tracheal intubation was facilitated by administration of vecuronium 0.1 mg kg-1. Heart rate, systolic blood pressure, endtidal CO2, OCR, arrhytmias and number of muscles being operated were recorded during the operation. Postoperative nausea and vomiting were also recorded.Both groups were similar with respect to number of operated muscles, endtidal CO2 values. The incidence of OCR was lower in Group S, which was a statistically significant finding (p

Özet

Çalışmamızda, şaşılık cerrahisi sırasında major bir problem olan okulokardiyak refleks üzerine sevofluran ile midazolamın etkilerini karşılaştırmayı amaçladık.Çalışma, fakülte etik kurulu ve ailelerinin onayı alınan, elektif tek taraflı şaşılık cerrahisi uygulanacak, 1-7 yaşlarında, ASA I grubundan 40 çocuk olguda gerçekleştirildi. Premedikasyon amacıyla tüm hastalara peroral atropin ve midazolam uygulandı. Olgular rasgele iki gruba ayrılarak, Grup S'de sevofluran, Grup M'de midazolam uygulandı. Grup S'de anestezi indüksiyonu için yüz maskesi ile %8 sevofluran ve % 40 O2/ % 60 N2O kullanıldı. Anestezi idamesinde ise % 2 sevofluran uygulandı. Grup M'de midazolam, anestezi indüksiyonunda 0.5-1 mg kg-1 iv ve anestezi idamesinde 4 µg kg dk-1 dozlarında uygulandı. Her iki grupta da anestezi idamesinde % 40 O2 /% 60 N2O karışımı kullanıldı. Tüm hastalar, 0.1 mg kg-1 vekuronyum verilerek entübe edildiler. Ameliyat boyunca kalp hızı, sistolik kan basıncı, endtidal CO2, okulokardiyak refleks ve aritmi olup olmadığı, opere edilen kas sayısı ve postoperatif bulantı-kusma kaydedildi.Her iki grupta kas sayıları ve endtidal CO2 değerleri benzerdi. Okulokardiyak refleks insidansı anlamlı şekilde sevofluran grubunda düşük bulundu (p=0.001). Postoperatif bulantı-kusma insidansı ise her iki grupta da düşüktü.Sonuç olarak, sevofluran çocuk şaşılık cerrahisi için uygun bir ajan olup, peroral premedikasyonla desteklendiğinde okulokardiyak refleks insidansını belirgin azaltmaktadır.
