بررسی اثربخشی افزودن وراپامیل و سوفنتانیل به لیدوکایین در بلوک شبکه بازویی در جراحی‌های اندام فوقانی در یک کارآزمایی بالینی تصادفی شده

Background and aimsAlthough calcium channel blockers such az verpamile are added to local anesthetics for regional anesthesia,rarely they may cause undesirable hemodynamic side effects This study compared the hemodynamic and blockade effects of verapamile and sufentanile during axillary brachial plexus blockade with lidocaine 1.5% .MethodsForty five patients were divided randomly into 3 groups. Patients in group 1 received 1.5% lidocaine patients group 2 received 105% lidocaine mixed with 5 mg verapamilepatients in group 3 received 1.5% lidocaine mixed with 5 mg verapa,ile and 5 μg sufentanile . Hemodynamic data were measured four times. The duration time of anesthesia and sensory block was recorded.ResultsThe beginning time of anesthesia was similar in 3 groups, but analgesia duration was significantly longer in groups 3 and 2 than in group 1 (p<0.05) . There were no significant differences in Hemodynamic data between 3 groups.ConclusionsVerapamile offers more stable hemodynamics and similar blockade, and thus may be beneficial for ASA I patients undergoing forearm and hand surgery.
