STUDY DESIGN: Systematic review.
OBJECTIVES: To systematically review the evidence on the use of local analgesics, specifically lidocaine or bupivacaine, to prevent autonomic dysreflexia (AD) during iatrogenic procedures or bowel and bladder care routines in individuals with spinal cord injury (SCI).
METHODS: A keyword search of MEDLINE, CINAHL, CENTRAL, Cochrane Reviews, PsycInfo, Embase, and Web of Science databases identified all English-language studies evaluating the efficacy of local analgesics in reducing AD. Included studies were either randomized controlled trials (RCTs) or quasi-experimental studies. Participants were adults with chronic SCI who received local analgesics prior to AD-triggering procedures or routines. Additionally, studies were required to report blood pressure values as an outcome. The methodology of this review followed the PRISMA checklist and was registered with PROSPERO (CRD42021219506).
RESULTS: Four RCTs and two quasi-experimental studies met inclusion criteria. Results were narratively synthesized as meta-analysis was not possible due to heterogeneity across studies included in the review. All six studies administered lidocaine. Lidocaine was found to have a beneficial effect on AD in three studies, no effect in two studies and a detrimental effect in one study.
CONCLUSIONS: Presently, RCTs and quasi-experimental studies on the use of lidocaine for reducing AD in individuals with SCI had small sample sizes and opposing findings. There is a strong need for definitive, well-monitored clinical trials with adequate sample sizes. Presently there is not enough compelling evidence to support or refute recommendations for the use of lidocaine from the AD management clinical practice guidelines.
