Rebound pain is extreme pain that persists after the effects of regional anesthesia wear off. Rebound pain occurrence and intensity are influenced by patient, surgical, and anesthesia-related factors. The incidence and severity of rebound pain after peripheral nerve block resolution are both reduced by the use of perioperative multimodal strategy. The purpose of the current paper was to evaluate the frequency, seriousness, and risk factors for rebound pain following peripheral nerve block resolution.
A cross-sectional study centred on 384 patients who had received peripheral nerve blocks was carried out from August 20, 2021, to June 30, 2022. A semi-structured questionnaire was used to gather information within 24 h following the block's performance. SPSS 25 was used to enter and analyze the data. The change from well-controlled pain while the block is operating to severe pain within 24 h of block performance is known as rebound pain. Both univariate and multivariable analyses were used to examine the relationship between various parameters (patient, surgical, and anesthetic-related factors) and rebound pain. In the multivariable analysis, a P-value of 0.05 or lower is regarded as statistically significant.
The incidence of rebound pain after peripheral nerve block was resolved was 61.7% (95% CI: 56.5–66.7) with a mean rebound pain score of 4.19 ± 2. Of the total 237, 120(50.6%) had severe rebound pain after the peripheral nerve block was resolved. The use of preoperative intravenous dexamethasone (AOR: 2.6, 95%CI: 20.29–24.57), preoperative pain (AOR: 3.9, 95%CI: 41–57.4), type of surgery (AOR: 6.5, 95%CI: 1.45–11.7), post-operative NSAID (AOR: 2.2, 95%CI: 17.69–20.8), and opioid use (AOR: 2.2, 95%CI: 19.1–22.56) were independent risks associated with rebound pain.
and Recommendation: Rebound pain occurred in 61.7% of patients and had independent associations with preoperative pain, dexamethasone premedication, type of surgery, use of an adjuvant, use of postoperative opioids, and NSAIDs. Therefore, clinicians should continue to use preventative strategies, especially for patients at higher risk of experiencing rebound pain.
•Incidence of rebound pain was 61.7%.•Preoperative pain, premedication with dexamethasole, type of surgery, use of adjuvant, and postoperative analgesia were factors for rebound pain.•It is recommended to use preventative strategies.
