Comparison of Outcome of Median and Paramedian Spinal Anaesthesia in Patients Undergoing Elective Lower Abdominal General

Abstract

Objective: To evaluate the risk of postdural hypotension and postdural pulsus paralysis (PDPH and PDPB,  respectively) in patients following elective lower abdomen general operations under spinal anesthesia. 
Study Design: Randomized Controlled Trial study 
Place and Duration of Study: This study was conducted at the Department of Anesthesia DHQ, Gujranwala from 
December 27, 2021 to June 27, 2022 
Methods: After approval of hospital ethical committee a total of 216 cases (108 cases in each group) were enrolled 
after taking informed consent. Their basic demographical details, contact details and type of surgery was noted. All 
procedures were done by single anesthesiologist to ensure the no bias. Patients were randomly divided into 2 groups 
using lottery method. 
Results: The mean age of patients in median and para median groups were 37.20 ± 12.31 years and 38.38 ± 11.59 
years. In Median group, there were 37(34.26%) male and 71(65.74%) female cases while in Para median group there were 44(40.74%) male and 64(59.26%) female cases. The frequency of PDPH was statistically lower in Para medina  group (3.7%) as compared to Median group (18.5%), p value < 0.05. The frequency of PDPB was also statistically  lower in Para median group (4.6%) as compared to Median group (13.9%), p-value < 0.05. 
Conclusion: The incidence of PDPH and PDPB was found less in para median group as compared to median spinal  anesthesia in patients undergoing elective lower abdominal general surgeries.
