Abstract

Purpose: This study aimed to evaluate the feasibility of real-time intraoperative pain assessment using a digital force gauge during vitreoretinal surgery under sub-Tenon's anesthesia.

Methods: In this prospective observational study, 63 patients undergoing vitreoretinal surgery under sub-Tenon's anesthesia were enrolled between April and August 2023. The participants were asked to constantly compress a digital force gauge during the operation. The magnitude of the compressive force was directly proportional to the severity of pain they experienced. A Pain Index (PI) was derived from peak compressive force measurements to evaluate the intraoperative pain intensity. Immediately after the surgery, patients reported their intraoperative pain score and anxiety score using the Numerical Rating Scale (NRS). Concordance between PI and pain scores was analyzed using the intraclass correlation coefficient (ICC) and Kendall's tau-b analysis.

Results: The PI was slightly higher than the patient-reported pain scores (1.37 ± 1.27 vs. 1.05 ± 1.28, P = 0.01). Complete consistency in values was observed in 33 cases (52.38%). Strong concordance emerged between PI and pain score (ICC = 0.75, 95% CI: 0.62-0.84; P < 0.01), along with a significant rank-order correlation (τ = 0.66, P < 0.01). Moreover, the PI showed a weaker correlation with anxiety score (τ = 0.32, P = 0.02) compared to pain score (τ = 0.51, P < 0.01).

Conclusion: The PI demonstrated favorable consistency and correlation with the conventional NRS for pain evaluation.

玻璃体视网膜手术中使用数字测力仪评估术中疼痛:一项前瞻性可行性研究。
目的:本研究旨在评估在亚tenon麻醉下玻璃体视网膜手术中使用数字测力仪实时评估术中疼痛的可行性。方法:在这项前瞻性观察研究中,于2023年4月至8月在亚tenon麻醉下接受玻璃体视网膜手术的患者共63例。参与者被要求在手术过程中不断压缩一个数字力计。压缩力的大小与他们所经历的疼痛程度成正比。通过峰值压缩力测量得出疼痛指数(PI)来评估术中疼痛强度。手术后,患者立即使用数字评定量表(NRS)报告术中疼痛评分和焦虑评分。采用类内相关系数(ICC)和Kendall's tau-b分析PI与疼痛评分之间的一致性。结果:PI评分略高于患者自述疼痛评分(1.37±1.27∶1.05±1.28,P = 0.01)。33例(52.38%)完全吻合。PI与疼痛评分具有较强的一致性(ICC = 0.75, 95% CI: 0.62 ~ 0.84)。结论:PI与常规NRS在疼痛评价上具有较好的一致性和相关性。
