摘要
目的观察中凹卧位对脊麻下剖宫产低血压发生率的影响。方法足月妊娠择期剖宫产产妇120例均分为三组。脊麻后,A组立即平卧位;B组平卧,手术床左侧倾斜15度;C组采取中凹卧位,即头胸抬高20度,下肢抬高30度。比较三组产妇低血压的发生率。另选足月妊娠孕妇20例,以B超分别观察其在仰卧位、左倾卧位及中凹卧位下腔静脉内径的变化。结果 A组低血压的发生率高于B、C组[55.0%vs.37.5%、22.5%](P<0.05);C组低血压发生率明显低于B组(P<0.05)。B超显示:中凹卧位下腔静脉内径大于左倾卧位和仰卧位[(1.49±0.24)cmvs.(1.32±0.23)cm和(1.26±0.22)cm](P<0.05)。结论脊麻下剖宫产产妇采取中凹卧位可有效地防治低血压的发生。
Objective To observe the efficacy of concave horizontal position in preventing hypotension of patients undergoing cesarean section under spinal anesthesia.Methods One hundred and twenty women at term of pregnancy undergoing Cesarean section under spinal anesthesia were randomly assigned to three groups of A（supine position）,B（supine position with 15 degrees left lateral tilt）and C（concave horizontal position with an elevation of the chest for 20 degrees and the leg for 30 degrees）with 40 cases each.The incidence of hypotension was recorded and compared.The diameter of the inferior venae cava was measured by B-type ultrasound under three different positions in 20 cases of pregnancy at term.Results The incidence of hypotension was higher in group A than that in groups of B and C [55.0% vs.37.5% and 22.5%]（P0.05）,which was lower in group C than that in group B（P0.05）.The diameter of inferior venae cava was greater in the position as in group A than that in the position as in group B or in group A[（1.49±0.24）cm vs.（1.32±0.23）cm or（1.26±0.22）cm]（P0.05）.Conclusion Less incidence of hypotension occurres when patients take concave horizontal position for cesarean section under spinal anesthesia.
