Abstract
The objective of this study is to review the
incidence and associated factors contributing to failed spinal anesthesia, a well-known
complication associated with various factors that can lead to poor surgical outcomes.
Several factors contribute to this complication, including obesity, difficult spinal
needle insertion, spinal cord anomalies, improper medication administration, technical
errors, and co-morbidity. In summary, failed spinal anesthesia is a critical concern
that may lead to considerable morbidity and mortality. Therefore, appropriate
measures should be taken to mitigate this complication by analyzing potential risks,
adhering to proper techniques, and increasing awareness among anesthesia providers.
Objectives-To study the incidence and associated factors of failed spinal anesthesia
in adults who underwent elective surgery in Tikur Anbessa hospitals at Addis Ababa,
Ethiopia.
Methods-A prospective observational survey was conducted on 280 eligible adult
elective surgical patients July 1st to November 30th, 2023 at TASH, Addis Ababa,
Ethiopia. Simple random sampling method was employed for selecting samples. Data
was entered and analyzed with SPSS version 27. Bi-variate and multivariate logistic
regression analysis was done to access significance of factors associated with failed
spinal anesthesia.At 95% confidence interval a p-value of less than 0.05 was
considered as statistically significant.
Outcomes -The incidence of failed SA among the adult who underwent elective
surgery under SA was 18.5% (51/276)).Multivariate logistic regression analysis
showed that anaesthesia providers who had < 2 year of work experience (AOR
=8.195,95%CI = 3.324-20.205) , bloody CSF appearance during lumbar puncture
(AOR = 21.268, 95% CI = 8.564-52.81) and count of spinal attempted is more than
two times (AOR=3.262, 95%, CI=1.417-7.509) were found to be a significant factor
for SA.
