Comparison of the hemodynamic effects of etomidate between hypertensive and normotensive patients

Abstract

Objective: Comparison of the hemodynamic effect of ethomidate induction in normotensive and hypertensive patients. Methods: Forty ASA 1-2 patients were included. After informed consent were obtained, patients were divided into two group; Group H: Hypertensive patients, Group N: Normotensive patients. Fentanile and midazolam were administrated for premedication. Anesthesia induction was performed by etomidate 0.3 mg/kg and rocuronium 0.6 mg/kg. Arterial pressures and heart rates were measured at certain intervals: control, pre-intubation and 1, 3 and 5 min post-intubation. Myoclonic movements and hemodynamic parameters were noted by an anesthetist who was masked to the groups. Results: Hemodynamic parameters were higher in hypertensive patients but were in clinically tolerable limits. Conclusion: No hemodynamic instability was observed in anesthesia induction with ethomidate in neither hypertensive nor normotensive patients. J Clin Exp Invest 2014; 5 (2): 164-168

Öz

Amaç: Etomidat ile anestezi indüksiyonunun hipertansif ve normotansif hastalarda hemodinamik etkilerini karşılaştırmayı amaçladık. Yöntemler: Etik komite onayı ve hastaların yazılı ve sözlü onamları alındıktan sonra genel anestezi altında çeşitli elektif cerrahi girişim uygulanacak olan 40 ardışık ASA I-II hasta çalışmaya alındı. Hastalar rastgele 2 gruba ayrıldı: Grup H (Hipertnasif hastalar), Grup N (Normotansif hastalar). Hastalar anestezi indüksiyonundan önce fentanil ve midazolam ile premedike edildi. Anestezi indüksiyonu etomidat 0.3 mg/kg ve rokuornyum 0.6 mg/kg ile yapıldı. Arteriyal basınçlar ve kalp hızı şu zamanlarda ölçüldü: kontrol, entübasyon öncesi ve entübasyondan 1, 3, 5 dakika sonra. Grup ayrımından habersiz bir anestezist tarafından miyoklonik hareketler ve hemodinamik parametreler kaydedildi. Bulgular: Hemodinamik parametreler tüm dönemlerde hipertansif hastalarda daha yüksekti fakat kabul edilebilir klinik sınırlar içindeydi. Sonuç: Ne hipertansif ne de normotansif hastalarda anestezi indüksiyonunda etomidatla hemodinamik instabilite yoktu.
