To assess the effectiveness of using anterior chamber irrigation of unpreserved lidocaine 1% as anesthesia during cataract surgery.
Private group ophthalmology practice.
This study prospectively evaluated 1000 of 1012 consecutive eyes having temporal corneal incision cataract surgery to determine whether anterior chamber lidocaine provides adequate anesthesia for cataract surgery. Twelve eyes were excluded because the patients had preoperative sedation. Surgery on the remaining 1000 eyes was performed by one surgeon without patients receiving preoperative or intraoperative sedation or other medications other than the local anesthetic and dilating agents. Each received one drop of topical proparacaine before entering the operating room. After an initial corneal stab incision was made, 0.25 to 0.50 cc of unpreserved lidocaine 1% was irrigated into the anterior chamber.
One patient was so uncomfortable from the microscope that he required supplemental retrobulbar anesthesia. A second patient was extremely uncomfortable during the case but did not require supplemental anesthesia. Two patients received additional dosages of anesthetic because of discomfort late in the operation. The remaining 996 patients were comfortable and pain-free during the operation with a single dose of the anesthetic.
Anterior chamber irrigation with unpreserved lidocaine 1% was an effective method for anesthetizing an eye for temporal corneal incision cataract surgery.
评估在白内障手术中使用未保存的1%利多卡因前房冲洗作为麻醉方法的有效性。
私立眼科诊所。
本研究前瞻性评估了连续1012例接受颞侧角膜切口白内障手术患者中的1000例，以确定前房利多卡因是否能为白内障手术提供足够的麻醉。12例患者因术前使用镇静剂而被排除。其余1000例患者的手术由一名外科医生进行，患者在术前或术中未接受镇静或其他药物，仅使用局部麻醉剂和散瞳剂。每位患者在进入手术室前滴入一滴表面麻醉剂丙美卡因。在最初的角膜穿刺切口完成后，将0.25至0.50毫升未保存的1%利多卡因冲洗入前房。
一名患者因显微镜操作而感到非常不适，需要补充球后麻醉。第二名患者在手术过程中极度不适，但不需要补充麻醉。两名患者因手术后期不适而接受了额外剂量的麻醉剂。其余996例患者在手术过程中使用单剂量麻醉剂时感到舒适且无痛。
用未保存的1%利多卡因进行前房冲洗是一种有效的麻醉方法，可用于颞侧角膜切口白内障手术的眼部麻醉。
