Farklı propofol infüzyon hızlarının, indüksiyon dozu, süresi ve kan basıncına etkileri

Amaç: Propofolün kan konsantrasyonu, yaş, cinsiyet, vücut ağırlığı, doz, infüzyon hızı ve kalp debisi gibi pekçok faktörebağlıdır. Bu çalışmada birincil amaç, infüzyon hızının kan basıncı değişikliklerine etkisinin incelenmesidir. İkincil olarakindüksiyon süresi ve dozu incelenmiştir.Yöntem ve gereç: Propofol 200 (P200), 300 (P300) veya 400 (P400) mL st-1 hızlarına ayarlanmış bir perfüzör yardımı ileBIS monitorizasyonu altında, bilinç kaybı olana kadar, 72 erişkin, ASA I hastaya uygulandı. Kan basıncı, indüksiyon süresive propofol dozu değişimi 3 grup içinde incelendi.Bulgular: 200 mL st-1 grubundaki sistolik ve ortalama basınç düşüşleri (P = 0,001, P = 0,014 sırasıyla) anlamlı idi. İnfüzyonhızının artması ile sistolik kan basıncındaki düşüş anlamlı bulundu. Diastolik kan basıncı her iki grupta da değişmedi. Enkısa indüksiyon süresi 400 mL st-1 infüzyon hızında idi (P200’de 177 sn, P300’de 182 sn, P400’de 134 sn,*P = 0,003) veindüksiyonda kullanılan toplam propofol miktarı da bu hastalarda anlamlı fazla idi. Vücut ağırlıklarına göre hesaplanmışindüksiyon dozları sırası ile P200’de 2,32 mg kg-1, P300’de 2,64 mg kg-1, P400’de 2,85* mg kg-1 idi, *P = 0,012.Sonuç: Ortalama kan basıncındaki düşüş 200 mL st-1 lik grupta diğerlerine göre daha az idi. 400 mL st-1 lik gruptaindüksiyon süresi daha kısa ancak total propofol miktarı daha yüksek idi. Anestezi indüksiyonunda, propofol enjeksiyonuhemodinamik bozulmaya neden olmayacak şekilde yavaş verilmelidir.

Eff ects of diff erent propofol injection speeds on blood pressure, dose, and time of induction

Blood concentration of propofol depends on many factors, such as age, gender, body weight, dose, infusion rate, and cardiac output. This study primarily investigated the effect of infusion rate on blood pressure changes. Secondarily induction time and induction dose were studied. Materials and methods: Propofol was administered at 200 (P200), 300 (P300), or 400 mL h-1 (P400) until loss of consciousness using bispectral index (BIS) monitoring in 72 adult patients. Change in blood pressure, induction time, and dose of propofol were compared among 3 groups. Results: The decreases in systolic and mean arterial pressure were statistically significant in the P200 group (P = 0.001, P = 0.014 respectively). Systolic blood pressure decreased significantly as the infusion rate increased. Diastolic blood pressure did not change in either group. The duration of induction was shortest with 400 mL h-1 infusion rate (177 s in P200, 182 s in P300, 134 s* in P400,*P = 0.003) and the total propofol dose was significantly higher in these patients (2.32 mg kg-1 in P200, 2.64 mg kg-1 in P300 , 2.85* mg kg-1 in P400, *P = 0.012). Conclusion: The induction dose required for loss of consciousness increased with a faster rate of infusion while time for induction was shorter in P400 compared to P200 and P300, and the decrease in mean blood pressure was less after induction in P200. Propofol injection should be slow enough to prevent any hemodynamic deterioration in anesthesia induction.
