To observe the effect of methylene blue combined with ropivacaine intercostal nerve block on postoperative analgesia after autologous costal cartilage augmentation rhinoplasty.
In this study 100 female patients who underwent autologous costal cartilage comprehensive augmentation rhinoplasty in Chongqing Huamei Plastic Surgery Hospital from April to November 2021 were randomly divided into an experimental group and a control group, with 50 cases in each group. In the experimental group methylene blue was combined with ropivacaine intercostal nerve block as patient controlled intravenous analgesia (PCIA), and the control group was ropivacaine intercostal nerve block combined with PCIA. The visual analogue scale (VAS) scores of resting and coughing at 6 h (T1), 24 h (T2), 48 h (T3), 72 h (T4) after surgery were recorded and evaluated. At the same time, the number and times of oral analgesics were recorded as well as nausea, vomiting, burning pain and paresthesia.
The VAS scores of the experimental group were lower than those of the control group at all time points. At 6 h, 24 h and 48 h after surgery, the VAS score of the experimental group was lower than that in the control group, but the difference was not statistically significant (P > 0.05). The VAS score of calm 72 h after surgery in the experimental group was significantly lower than that in the control group (P < 0.05). The analgesic effect of the two groups was better when they coughed after surgery. At 6 h after surgery, the VAS score of coughing in the experimental group was lower than that in the control group, but the difference was not statistically significant (P > 0.05); At 24 h, 48 h and 72 h after surgery, the VAS score of the coughing state in the experimental group was significantly lower than that in the control group (P < 0.05).
Intercostal nerve block with methylene blue combined with ropivacaine can achieve good postoperative analgesic effects in augmentation rhinoplasty with autologous costal cartilage.
观察亚甲蓝复合罗哌卡因肋间神经阻滞对自体肋软骨综合隆鼻术后镇痛的影响。
选取 2021 年 4 月至 11 月在重庆华美整形美容医院行自体肋软骨综合隆鼻术的 100 例女性患者，随机分为实验组和对照组，每组 50 例。实验组采用亚甲蓝复合罗哌卡因肋间神经阻滞联合患者自控静脉镇痛（PCIA），对照组采用罗哌卡因肋间神经阻滞联合 PCIA。记录并评估术后 6 h（T1）、24 h（T2）、48 h（T3）、72 h（T4）静息和咳嗽时的视觉模拟评分（VAS），同时记录口服镇痛药的次数和次数，以及恶心、呕吐、烧灼感和感觉异常。
实验组各时间点 VAS 评分均低于对照组。术后 6 h、24 h 和 48 h，实验组 VAS 评分低于对照组，但差异无统计学意义（P>0.05）。术后 72 h 实验组安静时 VAS 评分明显低于对照组（P<0.05）。两组术后咳嗽时镇痛效果均较好。术后 6 h 实验组咳嗽时 VAS 评分低于对照组，但差异无统计学意义（P>0.05）；术后 24 h、48 h 和 72 h，实验组咳嗽状态时 VAS 评分明显低于对照组（P<0.05）。
亚甲蓝复合罗哌卡因肋间神经阻滞可在自体肋软骨隆鼻术中获得良好的术后镇痛效果。
