To evaluate if the use of lidocaine gel applied to the cervix prior to manual vacuum aspiration (MVA) in addition to paracervical blockade is useful in reducing the level of pain associated with the procedure.
A total of 88 patients were randomized to receive either 5 mL of lidocaine gel or a placebo applied topically to the cervix 5 minutes prior to paracervical blockade. Both groups received the same drugs for pain control (tramadol hydrochloride, diazepam, and sodium diclofenac). A visual analogue scale (VAS) was used for evaluation of pain intensity at two times: 2 minutes before the blockade (directly after tenaculum clamping of the anterior aspect of the cervix) and after MVA of the uterine cavity.
There was a statistically significant difference in pain intensity between the arms of the study. At the first evaluation time (cervical clamping), VAS pain score for the placebo group (control) was 3.6 (2.1) and that for the lidocaine gel group (case) was 1.2 (1.4) (P < 0.01). At the second evaluation time (after manual vacuum aspiration), VAS pain score perceived by the control group was 5.3 (2.5) and that for the case group was 3.1 (1.9) (P < 0.01). The use of lidocaine gel was not associated with any adverse effects of interest.
The use of a topical lidocaine gel plus paracervical blockade was effective in reducing the intensity of pain associated with MVA when compared to paracervical blockade alone.
评估在宫颈旁阻滞基础上,于手动真空抽吸术(MVA)前将利多卡因凝胶应用于宫颈是否有助于降低该手术相关的疼痛程度。
总共88例患者被随机分为两组,一组在宫颈旁阻滞前5分钟接受5毫升利多卡因凝胶局部应用于宫颈,另一组接受安慰剂。两组均使用相同药物进行疼痛控制(盐酸曲马多、地西泮和双氯芬酸钠)。采用视觉模拟评分法(VAS)在两个时间点评估疼痛强度:阻滞前2分钟(宫颈前位钳夹后立即评估)和子宫腔MVA术后。
研究组间疼痛强度存在统计学显著差异。在第一个评估时间点(宫颈钳夹时),安慰剂组(对照组)的VAS疼痛评分为3.6(2.1),利多卡因凝胶组(病例组)为1.2(1.4)(P<0.01)。在第二个评估时间点(手动真空抽吸术后),对照组的VAS疼痛评分为5.3(2.5),病例组为3.1(1.9)(P<0.01)。利多卡因凝胶的使用未出现任何相关不良反应。
与单纯宫颈旁阻滞相比,局部应用利多卡因凝胶联合宫颈旁阻滞可有效降低与MVA相关的疼痛强度。
