Incidence of postspinal headache and low backache following the median and paramedian approaches in spinal anesthesia

Background and Aims: Postspinal headache and low backache are common complaints following spinal anesthesia which regresses spontaneously but sometimes becomes very troublesome for the patient as well as for the anesthesiologists. The aim of this study was to evaluate the incidence of postspinal headache and low backache after spinal anesthesia in lower abdominal surgery. Materials and Methods: One hundred patients of 18–60 years of age group with patients physical status the American Society of Anesthesiologists Class I or II after due consent divided into equal numbers of two groups: median (M) approach and paramedian (P) approach scheduled for lower abdominal surgery. Group M (50 patients) received spinal by median approach while in Group P (50 patients) received spinal by paramedian approach. The incidence of postspinal headache and low backache was observed in each group. All the patients were observed up to 7 days postoperatively. Data collected was analyzed statistically by SPSS (IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp) and Chi-square test, and P Results: Postspinal headache was observed to be 4% in paramedian approach and 20% in median approach group. Backache incidence recorded in both the groups was 2% and 10%, respectively. P value calculated statistically was Conclusion: Incidence of postspinal headache and low backache is less in paramedian approach than in median approach.
