척추마취와 전신마취 후 요통의 발생 빈도

Abstract

Background: Most of the back pain after spinal anesthesia remain temporarily, sometimes it may require treatment and reduce satisfaction of anesthesia. The incidence of postoperative low back pain after spinal or general anesthesia was different among authors. But many people believe that the post operative low back pain after spinal anesthesia would be more frequent and this belief could influence the choice of anesthesia. So, the author compared the incidence of low back pain after spinal anesthesia with general anesthesia for knee operation. Methods: Four hundred patients (ASA 1-2, age 15-65) presented for elective knee operation. Patient were allocated into two groups to receive spinal anesthesia (Group S, n=200) or general anesthesia (Group G, n=200) with medical record review. The incidence of postoperative low back pain at two days after surgery were compared between group S and group G. Statistical analysis was performed with logistic regression, Chi-square test or Fishers exact test. Results: The incidence of postoperative low back pain was 12.8%(25/200) in group S and 13.6%(27/200) in group G. There was no statistical difference between two groups. Postoperative low back pain was more frequent at operations lasting more than 60 min (p<0.05). Conclusion: The type of anesthesia was not associated with postoperative low back pain. However, the opeation duration more than 60min was a significant factor affecting postoperative low back pain. Key Words: General anesthesia, Low back pain, Spinal anesthesia
