Background: -Spinal anesthesia is one of the routinely done anesthetic procedures in practice. After spinal anesthesia backache is one of the complications causing dissatisfaction or discomfort in patients and leading to rejection of the technique for next operations.
Objectives: - the aim is to assess prevalence and associated factors of backache after spinal anesthesia in surgical procedures from October to January at Asella teaching and referral hospital, Asella, Ethiopia,2016.
Methods: - Institutional based cross-sectional study design was conducted. All patients who undergo spinal anesthesia at Asella Teaching and Referral Hospital during study period were included. Study participants were selected by systematic random sampling technique. Data was collected by two BSC anesthetists and supervised by one MSC Anesthetist. Training was given for data collectors and supervisors. Regular supervision and follow up was made. Data was entered to SPSS version 20 program for analysis. Odd ratio and 95% confidence interval was computed. Multivariate logistic analysis was used to identify factors associated with post spinal backache.
Results: - Total of 318 participants were included in our study. Findings from post-operative 1st,2nd,3rd days and 4th week showed 38.0%,29.9%,16.0% and 31.6% of the patients suffered backache respectively. Common factors which had association with postspinal backache from multivariate logistic regression at postoperative 1st ,2nd,3rd days and 4th week were history of previous backache and previous spinal anesthesia. Factors which had association with post spinal backache from multivariate logistic regression at postoperative 4th week were needle size, 18 and 21 gauge needle size (AOR = 3.686, 95% CI: 0.398, 34.183 and AOR = 2.410, 95% CI: 0.430, 13.503).
Conclusion and recommendation: - Our study confirmed that prevalence of post spinal backache at post-operative 1st, 2nd, 3rd days and 4th week data showed 38.0%, 29.9%, 16.0% and 31.6% of the patients respectively. We recommend use of lesser and less traumatic spinal needles, infiltration of injection site with local anesthetic.
