What is the optimal dose of intrathecal meperidine in open prostate surgery? A prospective double-blind randomized study

Objectives: This study was an analysis of the effect of different dosages of intrathecal meperidine (40 mg, 50 mg, 60 mg, and 70 mg) on hemodynamic parameters, the duration of neural blockade, and the incidence of meperidine-related side effects in patients who underwent an open prostatectomy. Methods: Sixty patients who underwent an open prostatectomy with combined spinal-epidural anesthesia were included. The patients were allocated to receive 1 of 4 different dosages of intrathecal meperidine (n=15 for each group): Group I: 40 mg, Group II: 50 mg, Group III: 60 mg, and Group IV: 70 mg. The duration of the block procedure, surgery duration, highest sensory block level, and anesthetic complications were recorded and analyzed. Results: At 20 minutes after the spinal injection, the maximum sensory block level was T6 in Group I and II, and it was T5 in Group III and IV. The mean motor block scores at 20 minutes after the spinal injection were lower in Group I compared with the other groups (p

Açık prostat cerrahisinde intratekal meperidinin optimal dozu nedir? Bir prospektif çift-kör randomize çalışma

Amaç: Bu çalışmada; açık prostatektomi uygulanan hastalarda, farklı dozlarda intratekal meperidinin (40 mg, 50 mg, 60 mg ve 70 mg) hemodinamik parametreler, nöral blokaj süresi ve meperidine bağlı yan etki görülme sıklığı üzerindeki etkisini araştırdık. Gereç ve Yöntem: Kombine spinal epidural anestezi ile açık prostatektomi uygulanan 60 hasta çalışmaya alındı. Hastalar dört doz intratekal meperidinden birini almak üzere (her grup için n=15) sahip olmak üzere ayrıldı: Grup I: 40 mg, Grup II: 50 mg, Grup III: 60 mg, Grup IV: 70 mg. Blok işleminin süresi, ameliyat süresi, en yüksek duyusal blok düzeyi ve anestezik komplikasyonlar kaydedildi. Bulgular: Spinal enjeksiyondan 20 dakika sonra, grup I ve II’de maksimum duyusal blok seviyesi T6 idi ve grup III ve IV’de T5 idi. Spinal enjeksiyondan 20 dakika sonra ortalama motor blok skorları grup I’de diğer gruplara göre daha düşük olarak bulundu (hepsi için p
