Abstract

Objective: Hypotension which is a complication due to sympathectomy is seen in approximately 60-80% of pregnant women receiving spinal anesthesia which creates appropriate conditions for caesarean section by means of rapid, deep, symmetric sensory and motor block. We aimed to determine the effectiveness of passive leg raising in preventing or reducing the depth of hypoten- sion occured after spinal anesthesia in pregnant women. Method: Forty pregnant women scheduled for cesarean section under spinal anesthesia, between the ages of 18-40 were included in the study.After preoperative administration of ant- acid prophylaxis and loading doses of 15 ml kg colloid to all patients, highly concentrated 2.2 ml bupivacaine was delivered through L4-5 interspace. After the injection, passive leg raising group were laid in supine position, and operating table was set to predetermined position and legs of the patients were raised to an angle of 30° with their waists. While the control group were left in the supine position. Patients’ hemodynamic values were recorded before and 2., 4., 6., 8., 10., 13., 16., 19., 21., 24., 27., 30 minutes after spinal anesthesia. Also the baby’s weight, APGAR score and blood gases were measured. Results: Demographic characteristics of the patients were similar and adequate and bilateral block level was achieved in all patients.Systolic arterial pressure were lower at 4. and 6. minutes in the control group and at 16. minutes in the passive leg raising group. The number of patients requiring ephedrine, total amount of ephedrine, and the incidence of hypotension were signifi- cantly lower in the passive leg raising group. There was no significant difference between both groups in neonatal evaluation. Considered all patients, as well as intragroup comparisons, there was no difference between the groups with regard to presentation style of pregnant women for cesarean, periods of fasting and weight of infants. Conclusion: Although passive leg raising maneuver after spinal anesthesia did not prevent devel- opment of hypotension completely, it was determined that it effectively reduced incidence and severity of hypotension.

Özet

Amaç: Hızlı, derin, simetrik duyusal ve motor blok sağlayarak sezaryen için uygun şartları sağla- yan spinal anestezide sempatektomiye bağlı bir komplikasyon olan hipotansiyon gebelerde yak- laşık %60-80 arasında görülmektedir. Çalışmamızda, gebelerde pasif bacak kaldırma uygulama- sının spinal anestezi sonrası oluşan hipotansiyonu önleme ya da derinliğini azaltmadaki etkinliği- ni belirlemek amaçlanmıştır. Yöntem: Çalışmaya spinal anestezi ile sezaryen yapılması planlanan 18-40 yaş arası 40 gebe dahil edildi. Tüm hastalara preoperatif 15 ml kg-1 kolloid yüklemesi ve antiasid profilaksisi sonrası L4-5 aralığından 2,2 ml yüksek dansiteli bupivakain intratekal olarak verildi. Enjeksiyon sonrası pasif bacak kaldırma grubundaki hastalar supin pozisyona alınarak ameliyat masası önceden işaretlen- miş olan pozisyona getirilip bacakların belden 30 derecelik açılanması sağlandı. Kontrol grubun- daki hastalar ise supin pozisyonda bırakıldı. Hastaların spinal anestezi öncesi ve sonrası 2., 4., 6., 8., 10., 13., 16., 19., 21., 24., 27. ve 30. dk.’lardaki hemodinamik verileri kaydedildi. Ayrıca bebe- ğin kilosuna, APGAR skoruna ve kan gazı değerlerine bakıldı. Bulgular: Çalışmaya dahil edilen hastaların demografik özellikleri benzerdi ve tamamında sezaryen için bilateral yeterli blok seviyesi elde edildi. Sistolik arter basıncı 4. ve 6. dk.’larda kontrol grubunda, 16. dk.’da ise pasif bacak kaldırma grubunda daha düşük bulundu. Efedrine gereksinim duyan hasta sayısı, total uygulanan efedrin miktarı ve hipotansiyon insidansı pasif bacak kaldırma grubunda anlamlı olarak düşük bulundu. Neonatal değerlendirmede her 2 grupta da anlamlı fark yoktu. Gebelerin sezaryen için geliş şekilleri, açlık süreleri ve bebeklerin kiloları arasında hem grup içi kar- şılaştırmalarda hem tüm hastalara bakıldığında gruplar arasında fark olmadığı belirlendi. Sonuç: Spinal anestezi sonrası yapılacak pasif bacak kaldırma manevrasının hipotansiyonu tama- men önlemese de insidansını ve derinliğini etkin bir şekilde azalttığı belirlendi.
