1、肌内注射法操作并发症肌内注射法（intramuscular injection）是将少量药液注入肌内组织内的方法。主要用于由于药物或病情因素不宜口服给药：要求药物在短时间内发生疗效而又不适于或不必要采用静脉注射；药物刺激性较强或药量较大，不适于皮下注射者。肌内注射亦可引起一些并发症，如疼痛、神经性损伤、局部或全身感染、疾病传播、硬结形成、针头堵塞及过敏性休克等，由于疾病传播、硬结形成、虚脱、过敏性休克、针头弯曲或针头折断等并发症其发生原因、临床表现及预防处理与皮内注射、皮下注射基本相同，此处不予重复叙述。本节详细叙述肌内注射发生的其它并发症。一、疼痛（一）发生原因肌内注射引起疼痛有多方面原因，
2、如针刺入皮肤的疼痛，推药时药物刺激皮肤的疼痛。一次性肌内注射药物过多、药物刺激性过大、速度过快。注射部位不当，进针过深或过浅等都可引起疼痛。（二）临床表现注射局部疼痛、酸胀、肢体无力、麻木。可引起下肢及坐骨神经疼痛，严重者可引起足下垂或跛行，甚至可出出下肢瘫痪。（三）预防与处理1、正确选择注射部位。2、掌握无痛注射技术。本组结果表明穴位按压肌内注射法，可减轻疼痛，按压的穴位为关元俞、太冲等穴位。进行股内注射前，先用拇指按压注射点10s，尔后常规皮肤消毒，肌内注射。国外有资料指出注射时如按常规操作，注射器内存在少量的空气可减少疼痛。用持针的手掌尺侧缘快速叩击注射区的皮肤（上般为注射区的右侧或下侧
3、）后进针，在一定程度上可减轻疼痛。精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 1 页，共 6 页3、配制药液浓度不宜过大，每次推注的药量不宜过快过多。股四头肌及上臂三角肌施行注射时，若药量超过2ml 时，须分次注射。经过临床试验，用生理盐水注射液稀释药物后肌内注射，比用注射用水稀释药物后肌内注射，能减轻病人的疼痛。4、轮换注射部位。预防与处理流程：二、神经性损伤（一）发生原因主要是药物直接刺激和局部高浓度药物毒性引起神经粘连和变性坏死。（二）临床表现注射当时即出现神经支配区麻木、放射痛、肢体无力和活动范围减少。约一周后疼痛减轻。但留有固定麻木区伴肢体功能部分或完全丧失，发
4、生于下肢者行走无力，易跌跤。局部红肿、疼痛，肘关节活动受限，手部有运动和感觉障碍，受累神经损伤程度：根据受累神经支配区运动、感觉障碍程度，分为完全损伤、重度损伤、中度损伤和轻度损伤。分度标准如下：完全损伤：神经功能完全丧失;选择正确注射部位掌握无痛注射技术配制药液浓度不宜过大，每次推注的药量不宜过快过多轮换注射部位精品w o r d 学习资料 可编辑资料-精心整理-欢迎下载-第 2 页，共 6 页文档编码:CC4O6Z4J6J5 HO2Z7O2F1G1 ZC10M2X5M1I5文档编码:CC4O6Z4J6J5 HO2Z7O2F1G1 ZC10M2X5M1I5文档编码:CC4O6Z4J6J5 H
