背景： 预先注射局麻药可以预防切口部位的术后疼痛，但镇痛效果不足，维持时间较短。地普司潘是速效倍他米松磷酸钠和长效倍他米松二丙酸盐的组合。地普司潘作为局麻药的辅助剂是否能减轻开颅术后的疼痛尚未研究。 

方法： 这是一项前瞻性、单中心、盲 法 、随机、对照临床研究，纳入年龄为18岁 至 64岁的患者，美国麻醉师协会（ASA）的身体状况 分级为 I至III， 予 择期行幕上开颅手术。我们筛选了2019年9月3日至2020年8月15日的患者。最后的后续工作于2021年2月15日完成。符合条件的患者被随机分配到 地普司潘 组(48例)或对照组(48例)， 地普司潘 组接受0.5%罗哌卡因加 地普司潘 的切口 浸润麻醉 治疗，对照组接受0.5%罗哌卡因（n=48） ， 分配比例为1:1。主要结果是在48小时内患者自控镇痛（PCA）累积舒芬太尼（μg） 的 用量 ，并在 手术后数小时 内， 根据 患者 意向治疗原则进行初步分析。 

结果: 两组患者之间的基线特征无显著差异（P>0.05）。在地普司潘组术后48小时内PCA累积舒芬太尼用量为5 (0-16)µg，显著低于对照组（38【30.5–46】µg；P<0.001）。      

结论: 罗哌卡因联合地普司潘的局部浸润麻醉可使开颅术后疼痛得到满意的缓解；这是一种简单、易行、安全，值得临床推广的技术。

Postoperative Analgesic Efficacy and Safety of Ropivacaine Plus Diprospan for Preemptive Scalp Infiltration in Patients Undergoing Craniotomy: A Prospective Randomized Controlled Trial

Abstract

Background

Preemptive injection of local anesthetics can prevent postoperative pain at the incision site, but the analgesic effect is insufficient and is maintained only for a relatively short period of time. Diprospan is a combination of quick-acting betamethasone sodium phosphate and long-acting betamethasone dipropionate. Whether Diprospan as an adjuvant to local anesthetic can achieve postcraniotomy pain relief has not been studied yet.

Methods 

This is a prospective, single-center, blinded, randomized, controlled clinical study, which included patients ages 18 and 64 years, with American Society of Anaesthesiologists (ASA) physical statuses of I to III, scheduled for elective supratentorial craniotomy. We screened patients for enrollment from September 3, 2019, to August 15, 2020. The final follow-up was completed on February 15, 2021. Eligible patients were randomly assigned to either the Diprospan group, who received incision-site infiltration of 0.5% ropivacaine plus Diprospan (n = 48), or the control group, who received 0.5% ropivacaine alone (n = 48), with a distribution ratio of 1:1. Primary outcome was the cumulative sufentanil (μg) consumption through patient-controlled analgesia (PCA) within 48 hours after surgery. Primary analysis was performed based on the intention-to-treat (ITT) principle.

Results 

Baseline characteristics were not significantly different between the 2 groups (P > .05). In the Diprospan group, the cumulative sufentanil consumption through PCA was 5 (0–16) µg within 48 hours postoperatively, which was significantly lower than that in the control group (38 [30.5–46] µg; P < .001).

Conclusion

Infiltration of ropivacaine and Diprospan can achieve satisfactory postoperative pain relief after craniotomy; it is a simple, easy, and safe technique, worth clinical promotion.
