Abstract
BackgroundThe effectiveness of preemptive analgesia (PA) for relieving postoperative pain and reducing the side effects of analgesics following video-assisted thoracoscopic surgery (VATS) has not yet been determined. This study intends to test the clinical application value of PA in the perioperative period of VATS.MethodsFrom January 2018 to August 2018, we divided patients who underwent VATS in our hospital into a trial group (PA group) and a control group (traditional analgesia group, TA group). The PA group received a PA program, and the TA group was administered a conventional postoperative analgesia scheme. We compared the two groups according to the intensity of postoperative pain using the numeric rating scale (NRS), the incidence rate of analgesic drug-related adverse reactions, and the severity of stress-induced inflammation.ResultsOne hundred five cases from the PA group, and 80 cases from the TA group were included in the analysis. There were no significant differences between the two groups in baseline characteristics (P>0.05). The PA group had a lower incidence rate of side effects from the analgesics compared to the TA group, and there was a statistical difference at 48 and 72 hours after surgery (P<0.05). The PA group had a slightly lower score than the TA group for postoperative resting pain. However, this difference was not statistically significant (P>0.05). The motion pain NRS score of the PA group was lower than the TA group, and although there were no significant differences at 4, 24, and 48 hours (P>0.05), there was a statistically significant difference at 72 hours (P<0.05). In the subset of patients with motion pain NRS ≥3 points, the PA group was marginally higher than the TA group at 4 hours (P>0.05) but was lower than the TA group at 24, 48, and 72 hours, with a statistically significant difference at 24 and 72 hours (P<0.05). There were no statistically significant differences in perioperative stress indexes between the two groups (P>0.05).ConclusionsPA can relieve postoperative pain following VATS and reduce the incidence rate of analgesic drug-related adverse effects.
