A comparison of the eff ects of intrathecal ropivacaine and bupivacaine during cesarean section

Amaç: Sezaryenlerde intratekal izobarik ropivakain ve bupivakain ile opioidlerin motor ve duyusal blok özelliklerine etkilerinin karşılaştırılması amaçlandı. Yöntem ve gereç: Elli iki gebe spinal anestezi için 25 μg fentanil + 100 μg morfi n ile % 0,5 izobarik bupivakain 10 mg (Grup B) veya % 0,75 izobarik ropivakain 15 mg (Grup R) vermek üzere rastgele iki gruba ayrıldı. Duyusal ve motor blok özellikleri kaydedildi. Bulgular: T6’da duyusal blok elde etme zamanı Grup B’de Grup R’den anlamlı olarak hızlıydı (2,7 ± 1,8 ile 4,2 ± 2,5 dk). Maksimum duyusal blok seviyesine ulaşma süresi Grup B’de Grup R’den hızlı bulundu (8,1 ± 4,1 ile 11,6 ± 5,6 dk). Grup B’de T10 ve L1 dermatomlarına gerileme süreleri (118,2 ± 24,2 ile 145,5 ± 28,1 dk, sırasıyla) Grup R’den daha kısaydı (135 ± 32,1 ile 162,5 ± 32,5 dk, sırasıyla). Motor blok süresi Grup B’de Grup R’den daha uzundu (165,8 ± 32,5 ile 135,2 ± 45,7 dk). Sonuç: İntratekal izobarik ropivakain ile opioidler daha uzun duyusal blok ve daha kısa motor blok süresiyle sezaryenler için bupivakainden üstün olabilir.

Sezaryenlerde intratekal ropivakain ve bupivakainin etkilerinin karşılaştırılması

Aim: To compare the eff ects of intrathecal plain bupivacaine or ropivacaine with those of opioids on sensory and motor block characteristics during cesarean section (C/S). Materials and methods: Fift y-two ASA I or II women were randomly allocated into 2 groups to administer either 10 mg of 0.5% plain bupivacaine (Group B), or 15 mg of 0.75% plain ropivacaine (Group R) with 25 μg fentanyl and 100 μg morphine for spinal anesthesia. Characteristics of the sensory and motor block were recorded. Results: Th e time to achieve sensory block at T6 was signifi cantly faster in Group B than in Group R (2.7 ± 1.8 min vs. 4.2 ± 2.5 min). Th e time to reach maximum sensory block was signifi cantly faster in Group B than in Group R (8.1 ± 4.1 min vs. 11.6 ± 5.6 min). Th e times of sensory block regression to T10 and L1 dermatomes were signifi cantly shorter in Group B (118.2 ± 24.2 min and 145.5 ± 28.1 min, respectively) than in Group R (135 ± 32.1 min and 162.5 ± 32.5 min, respectively). Motor block duration was significantly longer in Group B than in Group R (165.8 ± 32.5 min vs. 135.2 ± 45.7 min). Conclusion: Intrathecal plain ropivacaine with opioids might be superior to bupivacaine in terms of a longer sensory block, and a shorter motor block duration for C/S.
