Injury of the left common peroneal nerve caused by suspected sacral anesthesia:a case report and literature review
Sacral canal anesthesia is a common anesthesia method for anorectal and perineal area surgery.Sacral canal anesthesia has shortcomings such as a large amount of local anesthetic injection and differences in anesthesia effectiveness due to individual differences in the shape of sacral canal hiatus.However,due to its simple operation,low risk of central nervous system injury,limited anesthesia range,and low difficulty in intraoperative management,it is widely used in colorectal surgery.Sacral anesthesia is generally safe,and peripheral nerve injury after anesthesia is rare.In this paper,a case of impaired sensory and motor function in the left common peroneal nerve control area after anal fistula surgery under sacral anesthesia is reported.By analyzing the characteristics of the case,the diagnosis and treatment process and the treatment results,the possible reasons for the decline of sensorimotor function in the left common peroneal nerve innervation area are analyzed,and it is speculated that the peripheral nerve injury in this case is caused by the toxicity of local anesthesia drugs.In addition,combined with the literature review,it provides reference for avoiding similar situations in clinic in the future.
