Abstract
OBJECTIVES
We aimed to investigate whether ultrasound guided erector spinae plane block and serratus anterior plane block would provide effective and safe analgesia in patients with fracture ribs, and to detect their effects on diaphragmatic excursion in such cases.
DESIGN
Prospective double-blind randomized study.
SETTINGS
Tanta University Hospitals.
SUBJECT
Fifty adult patients ASA I, II with fracture ribs.
METHODS
Patients were randomized to receive either ultrasound guided erector spinae block (Group I) or serratus plane block (Group II) with injection of 19 ml bupivacaine 0.25% plus 1 ml dexamethasone (4 mg). Pain scores, 24 hour total analgesic requirements, diaphragmatic excursion and incidence of adverse events were recorded.
RESULTS
At rest and dynamic pain scores were significantly lower in Group I as compared to Group II from 2 hour up to 24 hour post block [median differences (95% CI): -1(-0.9999;0.0002), -1(-0.9999;0.0002), -1(-0.9998;0.0003), -1(-1.000;-0.000) and -1(-2.0000;-1.0000), -1(-0.9998;-0.0001), -1(-1.0001;-1.0002), -1(-2.000;0.000) respectively], with a significant reduction in 24h opioid consumption in Group I in comparison to Group II (P= 0.004*). Diaphragmatic excursion showed a significant improvement in Group I when compared to Group II at 2, 6, 12, and 24 hour after the block (p = 0.024*, 0.038*, 0.027*, 0.042* correspondingly). No adverse events were noted.
CONCLUSIONS
Both erector spinae block and serratus plane block provided safe and effective pain relief in traumatic rib fractures. Though the erector spinae group displayed significantly reduced pain scores, decreased analgesic needs and improved diaphragmatic excursion as compared to serratus group, nevertheless, this was of no clinical significance.
