Scalp defects can be reconstructed either with skin graft, local flaps, free flaps, or tissue expansion. Tissue expanders have been proved to be fruitful in the pediatric population. Scalp expansion has proved to be useful in the reconstruction of posttraumatic and postburn alopecic defects. Selective nerve block can be added for attenuation of sympathetic stimulation and decrease surgical stress in cranial surgeries. In this study, a comparison was done between using selective nerve block and without selective nerve block in both stages of tissue expansion procedure.
This study included 32 different children who underwent tissue expansions in the management of postburn alopecia. Pediatric patients presented with postburn alopecia of the scalp with mature scar were included in this work.
Postoperative analgesics were less in children who had received scalp block, whereas it was shorter in patients who did not receive any scalp block. Meperidine consumption was much more less in patients who received selective scalp nerve block. Pain score was markedly decreased in children who had received selective scalp nerve block in the immediate postoperative period. Children who received scalp block showed marked attenuation in the surgical stress responses with minimal changes in heart rate and mean arterial blood pressure after skin incision.
Scalp nerve block is considered an excellent choice for postoperative pain control with less need for opioid analgesia.
头皮缺损可通过植皮、局部皮瓣、游离皮瓣或组织扩张进行修复。组织扩张器已被证明在儿科患者中效果显著。头皮扩张已被证明在创伤后和烧伤后秃发缺损的修复中有用。在颅脑手术中可加用选择性神经阻滞以减轻交感神经刺激并降低手术应激。在本研究中,对组织扩张术两个阶段中使用选择性神经阻滞和不使用选择性神经阻滞的情况进行了比较。
本研究纳入了32例因烧伤后秃发接受组织扩张治疗的不同儿童。本研究纳入了头皮烧伤后秃发且瘢痕成熟的儿科患者。
接受头皮阻滞的儿童术后镇痛药用量较少,而未接受任何头皮阻滞的患者用药时间较短。接受选择性头皮神经阻滞的患者哌替啶用量少得多。接受选择性头皮神经阻滞的儿童术后即刻疼痛评分明显降低。接受头皮阻滞的儿童在皮肤切开后手术应激反应明显减轻,心率和平均动脉血压变化最小。
头皮神经阻滞被认为是术后疼痛控制的极佳选择,对阿片类镇痛药的需求较少。
