Abstract

Objective: Although valethamate bromide is used liberally to facilitate cervical dilatation, there is little and inconclusive data about its efficacy. The aim of this study was to determine the effect of valethamate bromide on the duration of labor. Materials and Methods: A total of 98 women with term pregnancies admitting to our clinic for vaginal delivery were included in this study. Patients were randomized to receive intramuscularly either 8 mg/ml valethamate bromide (n=48) or a similar amount of placebo (1 ml 0.9% NaCl; n=50) at the beginning of the active phase (i.e. cervical dilatation 4-5cm) of labor. The medications were given at hourly intervals for a total of three doses. Primary outcome measures were (1) time elapsed until the second stage of labor, (2) duration of the second stage of labor and (3) need for augmentation of labor with oxytocine. Secondary outcome measure was the subjective impression of the physician about the efficacy of the medication and associated adverse effects. Results: Maternal age (25.6±5.7 vs. 26.4±6.3 years), gestational age at delivery (39.0±1.5 vs. 38.9±1.8 weeks), birth weight (3285±334 g vs. 3252±460 g) and parity (27/48 vs 28/50 primipara) of both groups were comparable (p>0.05). The active phase of labor was significantly shorter in the valethamate bromide group than in the placebo group (200.2±88.3 vs. 267.2±131.3 minutes; p=0.04). Valethamate bromide shortened the active phase of labor in primiparas (210.3±93.5 vs. 287.1±130.3 minutes; p=0.015) but not in multiparas (187.1±81.4 vs. 241.9±131.1 minutes; p=0.11). The duration of the second stage of labor was comparable between both groups (39.1±50.9 vs. 58.0±120.9 minutes; p>0.05). The need for oxytocine was similar in both goups (9/48 vs. 6/50; p>0.05). The number of physicians who found that the medication was effective was significantly higher in the valethamate bromide group (39/48) than in the placebo group (28/50) (p=0.001). Discussion: Valethamate bromide administered during the active phase of labor significantly shortens the duration of the first stage of labor when compared with placebo

Özet

Amaç: Pratikte servikal dilatasyonu kolaylaştırmak amacı ile doğumun aktif fazında yaygın olarak kullanılan valetamat bromürün etkinliği konusunda kısıtlı sayıda çalışma bulunmaktadır ve bunların sonuçları çelişkilidir. Bu çalışmadaki amacı- mız, valetamat bromürün doğum süresi üzerine olan etkisini incelemekti. Materyal ve Metot: Kliniğimize normal vajinal do¤um için başvuran toplam 98 gebe çalışmaya dahil edildi. Hastalara aktif fazın başında (servikal dilatasyonun 4-5 cm olması) randomize olarak 1 saat ara ile toplam 3 kere 8 mg/ml valetamat bromür (n=48) veya aynı miktarda plasebo (1 ml %0.9 NaCl; n=50) intramüsküler olarak uygulandı. Primer sonuç olarak, doğumun ikinci evresinin başına kadar geçen süre, doğumun ikinci evresinin süresi ve oksitosin ile doğum eyleminin desteklenmesine ihtiyacı olup olmadığı değerlendirildi. Sekonder sonuç olarak ise, uygulamayı yapan hekimin verilen ilacı etkili bulup bulmadığı ve uygulama sırasında gözlenen yan etkiler de¤erlendirildi.Sonuç: Her iki grup anne yaşı (25.6±5.7 ve 26.4±6.3 y›l), doğumdaki gebelik haftası (39.0±1.5 ve 38.9±1.8 hafta), doğum tartısı (3285±334 g ve 3252±460 g) ve parite (27/48 ve 28/50 primipar) bakımından benzerdi (p>0.05). Valetamat bromür (200.2±88.3 dakika) verilen grupta plasebo (267.2±131.3 dakika) verilen gruba kıyasla doğumun birinci evresi anlamlğ derecede kısaydı (p=0.04). Valetamat bromür verilen primiparlarda (210.3±93.5 dakika) plasebo verilen primiparlara (287.1±130.3 dakika) kıyasla birinci evrenin daha kısa oldu¤u, multiparlarda ise valetamat bromürün travayın süresini anlamlı derecede kısaltmadığı görüldü (187.1±81.4 dakika ve 241.9±131.1 dakika; p>0.11). Doğumun ikinci evresinin uzunlu- ğu yönünden her iki grup benzerdi (39.1±50.9 ve 58.0±120.9 dakika; p>0.05). Her iki grupta oksitosin ile desteklenme ihtiyacı bakımından anlamlı fark bulunmadı (9/48 ve 6/50; p>0.05). Travay takibinde verilen ilacın etkili olduğu görüşü valetamat bromür grubunda (39/48) plasebo grubuna (28/50) k›yasla anlamlı oranda fazlaydı (p=0.001). Tartışma: Aktif fazda intramüsküler olarak verilen valetamat bromürün plaseboya kıyasla doğumun birinci evresini anlamlı derece kısalttığı tespit edilmiştir.
