背景:为了成功管理儿科牙科患者,局部麻醉对于消除手术期间或手术后的疼痛至关重要。下牙槽神经阻滞(IANB)后,从软组织麻醉中尽早恢复,应通过避免无意中咬伤软组织的风险使幼儿患者受益。
目标:因此,本研究的目的是(1)评估和比较布洛芬术前和术后对IANB麻醉伴或不伴PM患儿疼痛感觉的疗效;(2)评估甲磺酸酚妥拉明麻醉症状逆转所需的平均时间.
方法:本研究是一项随机,采用方便的抽样方法,在60名6~8岁儿童中进行临床试验.使用计算机生成的随机化序列将儿童随机分为四个相等的组,每组15人。使用2%利多卡因和1:100,000肾上腺素进行IANB麻醉,每组进行下颌初级磨牙牙髓切除术。第1组:在手术开始前1小时服用布洛芬片剂。第2组:开髓手术后30分钟布洛芬片。第3组:在手术开始前1小时服用布洛芬片剂,并给予甲磺酸酚妥拉明(PM)注射液。第4组:牙髓切除术后立即,给予PM注射,并在牙髓切除术后30分钟服用布洛芬片剂。评估所有儿童的软组织麻醉持续时间,他们的行为评分和疼痛评分,以及术后自我伤害的发生率。
方法:使用单向ANOVA比较各组之间麻醉症状逆转所需的平均时间。酚妥拉明的作用,局部麻醉药,与布洛芬对患儿的行为和疼痛评分进行比较,采用t检验。对于这项研究,P<0.05被认为具有统计学意义。
结果:注射酚妥拉明可显著缩短舌唇麻醉症状完全逆转所需的时间(P<0.001)。使用酚妥拉明逆转或摄入布洛芬术前或术后没有表现出任何明显的行为变化。疼痛体验,或儿童自我伤害的发生率。
结论:很明显,虽然酚妥拉明注射液可以缩短麻醉时间,术前或术后辅助使用布洛芬并没有显著改变疼痛评分.
BACKGROUND: For successfully managing pediatric dental patients, local anesthesia is essential to eliminate pain during or after the operative period. An early recovery from soft-tissue anesthesia after an inferior alveolar nerve block (IANB) should benefit a young child patient by avoiding the risk of inadvertently biting the soft tissues.
OBJECTIVE: Hence, the purpose of the study was to (1) evaluate and compare the efficacy of pre- and postoperative ibuprofen on pain perception in children who undergo IANB anesthesia with or without the use of PM and (2) evaluate the average time required for reversal of anesthesia symptoms using phentolamine mesylate.
METHODS: The present study was a randomized, clinical trial performed among 60 children between 6 and 8 years of age using a convenient sampling method. The children were randomly assigned into four equal groups of 15 each using the computer-generated randomization sequence. IANB anesthesia was performed using 2% lignocaine with 1:100,000 epinephrine, and a mandibular primary molar pulpotomy was performed on each group. Group 1: the ibuprofen tablet was taken 1 h before the onset of the procedure. Group 2: ibuprofen tablet 30 min after the pulpotomy procedure. Group 3: the ibuprofen tablet was taken 1 h before the onset of the procedure, and the Phentolamine mesylate (PM) injection was administered. Group 4: immediately after the pulpotomy, the PM injection was administered, and an ibuprofen tablet was taken 30 min after the pulpotomy procedure. All children were assessed for the duration of soft-tissue anesthesia, their behavior scores and pain rating, as well as the incidence of postoperative self-inflicted injuries.
METHODS: A one-way ANOVA was used to compare the average time needed for the reversal of anesthetic symptoms between groups. The effects of phentolamine, local anesthetics, and ibuprofen on the child\'s behavior and pain scores were compared using the Student\'s t-test. For the study, P < 0.05 was accepted as statistically significant.
RESULTS: The time needed for the full reversal of anesthetic symptoms to manifest on the tongue and lip was substantially reduced by the injection of phentolamine (P < 0.001). The use of phentolamine for reversal or the intake of ibuprofen pre- or postoperatively did not exhibit any significant variation in the behavior, pain experience, or incidence of self-inflicted injuries in the child.
CONCLUSIONS: It is evident that although phentolamine injections shorten the duration of anesthesia, the adjunctive use of pre- or postoperative ibuprofen did not significantly alter pain scores.
