To determine whether lidocaine 2% jelly is an effective topical anesthetic agent for cataract surgery.
Private practice and surgicenter.
One hundred eighty cataract surgery patients were randomly assigned to 1 of 4 groups of 45 patients each: Group 1-topical eyedrop anesthesia; Group 2-intracameral lidocaine; Group 3-lidocaine 2% jelly applied once, on arrival at the surgicenter; and Group 4-lidocaine 2% jelly applied on arrival and about 5 minutes prior to surgery. Each patient was asked about pain or pressure sensation during the operation and afterward.
Single instillation of lidocaine 2% jelly was associated with pain scores comparable to those with topical eyedrop anesthesia. When the jelly was readministered shortly before surgery, the pain scores were comparable to those with intracameral anesthesia.
Lidocaine 2% jelly was an effective agent in cataract surgery.
确定2%利多卡因凝胶是否为白内障手术有效的局部麻醉剂。
私人诊所和手术中心。
180例白内障手术患者被随机分为4组，每组45例：第1组——局部滴眼麻醉；第2组——前房内注射利多卡因；第3组——到达手术中心时一次性应用2%利多卡因凝胶；第4组——到达时及手术前约5分钟应用2%利多卡因凝胶。询问每位患者术中及术后的疼痛或压迫感。
单次滴注2%利多卡因凝胶的疼痛评分与局部滴眼麻醉相当。在手术前不久再次应用凝胶时，疼痛评分与前房内麻醉相当。
2%利多卡因凝胶是白内障手术的有效麻醉剂。
