心率变异性在减重患者手术前后心理状态评估中的应用

Application of Heart Rate Variability in Evaluation of Psychological Status of Patients with Weight Loss before and after Operation

摘要: 目的：探讨减重患者术前术后的心理状态变化。方法：回顾性分析2021年1月至2023年6月在江苏省中医院普外科行减重手术的患者25例，对比减重手术前1天、手术当天、术后第1天、术后1个月患者心率变异性各参数(SDNN、SDANN、RMSSD、PNN50、LF、HF、LF/HF)的变化。结果：术前1天与手术当天的SDNN为(111.00 (100.5, 132.00) vs 96.00 (86.50, 111.50)、SDANN为96.00 (83.50, 124.00) vs 82.00 (74.50, 106.00), P < 0.05，差异具有统计学意义；手术当天与术后1天相比：LF为414.00 (264.50, 611.50) vs 558.00 (250.50, 1068.50)、HF为389.00 (203.50, 596.00) vs 678.00 (370.00, 1243.50)、RMSSD为35.00 (27.50, 52.00) vs 48.00 (28.50, 64.00)、PNN50为5.43 (2.34, 11.88) vs 11.92 (4.38, 19.29)，P < 0.05，差异有统计学意义，LF较术前上升，P > 0.05，差异无统计学意义；术后1天与术后1个月：SDNN为89.00 (73.50, 116.50) vs 122.00 (93.00, 170.00)、SDANN为75.00 (51.50, 98.00) vs 86.00 (68.50, 134.50)、RMSSD为48.00 (28.50, 64.00) vs 60.00 (46.50, 70.00)、PNN50为11.92 (4.38, 19.29) vs 22.55 (8.03, 30.10)，P < 0.05，差异有统计学意义。结论：减重术后患者的心理(抑郁焦虑)状态较术前得到改善。

Abstract: Objective: To explore the preoperative and postoperative changes in the psychological state of weight loss patients. Methods: To retrospectively analyze 25 patients who underwent bariatric surgery at the General Surgery Department of Jiangsu Provincial Hospital of Chinese Medicine from January 2021 to June 2023 and to compare the changes of each parameter of heart rate variability (SDNN, SDANN, RMSSD, PNN50, LF, HF, and LF/HF) of the patients on the bariatric surgery, 1 day before the bariatric surgery, on the day of the surgery, on the 1st day of the surgery, and on the 1 month of the surgery. Results: Preoperative day 1 versus the day of surgery [SDNN (111.00 (100.50, 132.00) versus 96.00 (86.50, 111.50)], SDANN [96.00 (83.50, 124.00) versus 82.00 (74.50, 106.00)], P < 0.05, the difference is statistically significant; day of surgery compared with 1 day postoperatively: LF [414.00 (264.50, 611.50) vs 558.00 (250.50, 1068.50)], HF [389.00 (203.50, 596.00) vs 678.00 (370.00, 1243.50)], RMSSD [35.00 (27.50. 52.00) vs 48.00 (28.50, 64.00)], PNN50 [5.43 (2.34, 11.88) vs 11.92 (4.38, 19.29)], P < 0.05, the difference is statistically significant, LF increased compared to preoperative period, P > 0.05, the difference is statistically not significant; postoperative day 1 vs postoperative month 1: SDNN [ 89.00 (73.50, 116.50) vs 122.00 (93.00, 170.00)], SDANN [75.00 (51.50, 98.00) vs 86.00 (68.50, 134.50)], RMSSD [48.00 (28.50, 64.00) vs 60.00 (46.50. 70.00)], and PNN50 [11.92 (4.38, 19.29) vs 22.55 (8.03, 30.10)], P < 0.05, the difference is statistically significant. Conclusion: The psychological (depression-anxiety) status of the patients after bariatric surgery was improved compared with the preoperative period.
