This study was to find out the total duration of postoperative analgesia following circumcision in children when Tramadol was used as an adjunct to local anaesthetics in penile block.
Forty children of age 5 - 13 yrs, ASA I & II were enrolled in this study. Patients were premedicated with ketamine and atropine intramuscularly prior to separation from their parents and IV cannulation. Penile block was then performed under strict aseptic precautions with paramedian approach by 3 cm long 23 g ordinary needle where 4 ml of mixture of local anaesthetics and tramadol was given on each side of the base of penis at 11 and 2 o clock positions. Duration of analgesia was recorded from the time of completion of surgery till the patients' first complain of pain and when additional analgesic was given. Intraoperative analgesia duration achieved by the penile block was not included in this study due to unavoidable overlapping of sedation and analgesia produced by the premedicated IM Ketamine (4-5 mg/kg) ,which lasts for 25 minutes to 30 minutes. Unless complicated, this is the usual surgery time in our hospital for this procedure. Because of this reason, the sedation score was not used in this study. Moreover, paediatric sedation score remains too impractical and unreliable in our context.
Addition of Tramadol with local anaesthetics in penile block prolonged the postoperative analgesia even up to 40 hours.
Tramadol as an adjunct with Local Anaesthetics extends the duration of postoperative analgesia and can be used safely for this purpose in the children.
本研究旨在探讨在小儿包皮环切术中,将曲马多作为阴茎阻滞局部麻醉的辅助用药时术后镇痛的总时长。
本研究纳入了40名年龄在5至13岁、美国麻醉医师协会(ASA)分级为I级和II级的儿童。患儿在与父母分离并进行静脉置管前,先肌肉注射氯胺酮和阿托品进行术前用药。然后在严格的无菌操作下,采用旁正中入路,用3厘米长的23G普通针头进行阴茎阻滞,在阴茎根部11点和2点位置的两侧各注射4毫升局部麻醉药和曲马多的混合液。镇痛时长从手术结束时开始记录,直至患者首次主诉疼痛或给予额外镇痛药物时为止。本研究未纳入阴茎阻滞术中的镇痛时长,因为术前肌肉注射氯胺酮(4 - 5毫克/千克)产生的镇静和镇痛作用不可避免地存在重叠,其持续时间为25至30分钟。除非出现并发症,这是我院进行该手术的通常时长。因此,本研究未使用镇静评分。此外,在我们的实际情况中,小儿镇静评分仍然不太实用且不可靠。
在阴茎阻滞中,曲马多与局部麻醉药联合使用可延长术后镇痛时间,甚至长达40小时。
曲马多作为局部麻醉药的辅助用药可延长术后镇痛时间,且在此用于儿童时可安全使用。
