Abstract

Objective: Spinal anesthesia is commonly used in emergency and elective cesarean section because it provides rapid and adequate anesthesia. However, hypotension occurs in 40-85% patients after this type of anesthesia. Subarachnoid volume can be increased by spinal anesthesia besides increasing intra-abdominal pressure and narrowing subarachnoid space. It was aimed in this study to evaluate the effect of spinal anesthesia with constant subarachnoid volume by aspirating cerebrospinal fluid (CSF) on maternal hemodynamics and fetus during cesarean section. Method: Under sterile condition, subarachnoid space was reached at L4-L5 or L3-L4 intervertebral space with 25G Quinche blade spinal needle. After aspirating 2.4 mL CSF, 12 mg (2.4 mL) bupivacaine heavy was injected into subarachroid space in group A (n=32). In group B (n=33) only 12 mg (2.4 mL) bupivacaine heavy was injected subarachnoid space, without any CSF lost. Results: The time of reaching maximal sensory block was shorter significantly in group B (p<0,05). At the evaluations of blood gases of both uterine artery and uterine venous, mean pH value were lower significantly in group B (p<0,05). Ephedrine usage until birth was lower but not statistically different in group A (p>0,05). Cumulative ephedrine usage is similar in both groups. Conclusion: Taking CSF with the amount of planned administration of local anesthetic before subarachnoid injection decreases both risk of maternal hypotension and ephedrine usage till birth and may contribute the well conditions of fetus and baby.

Özet

Amaç: Spinal anestezi acil ve elektif sezaryen operasyonları sırasında hızlı ve yeterli anestezi sağladığı için sık kullanılmaktadır. Ancak bu girişim sonrasında hastaların %40~S5'inde hipotansiyonla karşılaşılmaktadır, intraabdominal basınç artışı ve subaraknoid boşluğun daralması ile zaten artmış olan subaraknoid basınç, spinal enjeksiyon ile daha da artabilir. Bu çalışmanın amacı sezaryen sırasında subaraknoid boşluğa uygulanan lokal anesteziğin neden olduğu basınç artışının, sabit yolum sağlanması ile engellenerek yapılan spinal anestezinin hemodinami ve seviye üzerine etkisini araştırmaktır. Yöntem: Oluru/ pozisyonda steril boyama ve örtme sonrasında L4-L5 veya L3-L4 aralığından Quincke uçlu 25G spinal iğne ile subaraknoid aralığa girildi. Grup A'da (n- 32) hastaya uygulanması planlanan bupivakaitı heavy (12 mg) hacmi kadar (2,4 ml) hastadan BOS aspire edildi. Grup B'de 0,05). Total uygulanan efedrin miktarı ise her iki grupta benzerdi. Sonuç: Spinal anestezi öncesi uygulanması planlanan lokal anestezik miktarı kadar beyin-omurilik sıvısı alındıktan sonra spinal anestezi yapılması maternal hipotansiyonu geciktirerek bebek çıkmadan önce maternal hipotansiyon oluşma riskini ve efedrin kullanımını azaltarak fetüsün ve bebeğin iyilik haline katkıda bulunabilir.
