Real-time ultrasound-guided retrobulbar block vs blind technique for cataract surgery (pilot study)

Abstract

BackgroundRetrobulbar regional eye block aims to ensure eye globe akinesia and anesthesia during ophthalmic surgery, and despite the rarity of occurrence of complications due to the blind needle passage while performing either peribulbar or retrobulbar block, some of them are serious and may be life threatening.AimThe aim of this study was to estimate the accuracy and safety of real-time ultrasound-guided retrobulbar regional anesthesia in comparison with the blind technique for cataract surgery.DesignThis was a prospective randomized controlled trial.MethodologyA total of 30 patients who met the inclusion criteria were registered in our research and were divided into two groups: 15 patients received real-time ultrasound-guided retrobulbar block compared to 15 patients who received the block using the blind technique.ResultsOne patient out of the 30 was excluded from the analysis, and no statistically significant differences were observed between the two groups regarding the onset of akinesia, numeric pain rating scores, rate of complications, and degree of patient and physician satisfaction.ConclusionThere were no statistically significant difference between real-time ultrasound-guided and blind retrobulbar regional eye blocks concerning the onset of action, total volume of injected local anesthetic solution, supplemental injection required, pain scores, and degree of patient satisfaction.

Inadvertent globe penetration during retrobulbar anesthesia: A case report

“…To reduce the risk of globe penetration in highly myopic eyes, it is advisable to use B-ultrasound examination to exclude staphyloma at the injection site preoperatively. Recently, Foad et al [ 6 ] explored the accuracy and safety of real-time ultrasound-guided retrobulbar regional anesthesia, as compared with blind technique, for cataract surgery. Foad et al [ 6 ] used the Siemens ® ACUSON X600™ Ultrasound System.…”

“…Ultrasound-guided retrobulbar regional anesthesia allows for real-time visualization as the needle advances and as local anesthetic spreads[ 6 ]. Foad et al [ 6 ] reported that ultrasound-guided retrobulbar injection may decrease risk for sight-threatening or life-threatening complications. However, our patients had no high-risk factors, and in this case, one possible explanation was that the younger surgeon lacked experience, resulting in an incorrect angle of needle insertion.…”

Ultrasound navigation during blockade in children with retinoblastoma with enucleation of the eyeball

“…N. Naguib et al сообщили, что начало блока, время и его качество были сопоста вимы, не отмечено никаких существенных различий в ПББ + УЗИ и традиционном методе [11]. Похожие результаты получили и A. Zaghloul et al при иссле довании РББ + УЗИ [12], хотя прямая визуализация с помощью УЗИ может помочь избежать уязвимых структур. Однако до настоящего времени не проводи лось исследований по эффективности и безопасности РББ + УЗИ по сравнению с ПББ + УЗИ при энуклеа ции глазного яблока у детей с РБ.…”
