Ultrasound-assisted modified paramedian
technique for spinal anesthesia in elderly
Abstract
Background: At present, there are two techniques which are widely applied clinically; the midline and the paramedian. Both methods are difficult for clinicians when treating the elderly. The aim of this work is to explore the feasibility of an ultrasound-assisted modified paramedian technique for spinal anesthesia in the elderly. This would provide clinicians with a new and easy-to-operate technique.
Methods: A total of 150 elderly patients who were scheduled for urology surgery under spinal anesthesia in our hospital were randomly divided into three groups (n = 50): (i) midline technique group (group M), (ii) paramedian technique group (group P), and (iii) modified paramedian technique group (group PM). All spinal anesthesia were performed by the same second-year resident.
Results: Compared with groups M and P , group PM had significantly higher first-attempt success rate (P < 0.05, especially in patients aged 65-74 years), fewer attempts (P < 0.05), and higher patient satisfaction score (P < 0.05). Compared with group M, the time taken to perform spinal anesthesia and the number of needle redirections were significantly reduced in group PM (P < 0.05). There was no statistically significant difference between groups PM and P . There were also no statistically significant differences in the cases of inconsistency between ultrasound-assisted and landmarkguided location of intervertebral space, the time taken to ultrasound-assisted location, the onset time to pain block at T10, the incidence of hypotension, anesthesia effect and the incidence of headache, lower back pain, or nausea and vomiting, within 24 h after surgery.
Conclusions: Compared with groups M and P , group PM had significantly higher first-attempt success rate (P < 0.05, especially in patients aged 65-74 years), fewer attempts (P < 0.05), and higher patient satisfaction score (P < 0.05). Compared with group M, the time taken to perform spinal anesthesia and the number of needle redirections were significantly reduced in group PM (P < 0.05). There was no statistically significant difference between groups PM and P . There were also no statistically significant differences in the cases of inconsistency between ultrasound-assisted and landmarkguided location of intervertebral space, the time taken to ultrasound-assisted location, the onset time to pain block at T10, the incidence of hypotension, anesthesia effect and the incidence of headache, lower back pain, or nausea and vomiting, within 24 h after surgery.
