Background: The quality of ophthalmic anesthesia is an important component of the surgical procedure. There is no absolutely well-tolerated local eye anesthetic technique. However, it is important to choose a technique with high efficacy and safety. Objective: This study aimed to compare the efficacy and safety of peribulbar block using medial canthus single injection and posterior sub-tenon injection techniques. Methods: This prospective observational study was carried out at the Research Institute of Ophthalmology, Cairo, Egypt during the period from March to December 2018. Consecutive 60 patients of both sexes, aged >18 years-old, scheduled for bilateral strabismus surgery were enrolled in this study. In one eye of the sixty patients, medial canthus single injection peribulbar anesthesia was used (Group A), whereas posterior sub-tenon technique was applied in the other eye (Group B). Results: The median total ocular akinesia score was significantly higher in group A than in group B when assessed at 1, 3, and 5 min (p < 0.001). Each of the intraoperative (at 5 min) and postoperative pain scores showed no significant differences between the two groups (p > 0.05). However, the median scores of surgeon and patient satisfaction were significantly higher in group A compared with group B (3 vs. 2 each, p < 0.05). No patient developed occulocardiac reflex or postoperative nausea and vomiting. Conclusion: Peribulbar anesthesia by medial canthus single injection showed better akinesia of the globe than sub-tenon injection technique. Otherwise, both techniques were equally effective and safe.

Digital Block

Background Regional anesthesia of a single finger is commonly achieved by the traditional ring block, which requires at least two painful injections in the digit. Single injection digital block techniques have been described to avoid this problem. Among these, the subcutaneous technique described by Harbison appears to be safe and to allow most procedures to be carried out with good tolerance. Objectives A prospective study was designed to evaluate the results of the subcutaneous technique in terms of patient tolerance, distribution of anesthesia and efficiency. Methods All blocks were performed by a single investigator. A visual analog scale was used to evaluate pain associated with the injection. Prick testing was used to evaluate the quality of anesthesia at the volar and dorsal aspects of the phalanxes. Tolerance to the surgical procedure and the need for additional injections were also recorded. Results This technique allowed surgery to be performed without complementary injection most of the time and was very well tolerated. The dorsum of the proximal phalanx, however, was unpredictably included in the anesthetized territory. Conclusion The subcutaneous single injection digital block is safe, efficient and easy to perform. It allows the treatment of all conditions on the volar aspect of the finger and on the dorsal aspect of the distal and middle phalanxes. For surgery on the dorsal aspect of the proximal phalanx, a combined single injection technique or a supplementary dorsal block should be used.

Loss Of Resistance

A technique for blocking the femoral nerve using a single needle placement is described. It depends on an appreciation of the anatomy and the need to feel loss of resistance twice as two fascial layers are penetrated during insertion of the needle just lateral to the femoral artery. A single injection of bupivacaine 0.35-0.5 per cent of at least 0.3 ml/kg will produce a satisfactory block.

SummaryObjectives: To investigate the specificity of anaesthesia of the deep branch of the lateral plantar nerve (DB-LPN).Methods: Twenty horses had DB-LPN anaesthesia performed by a single injection technique as part of a lameness investigation. The mechanical nociceptive threshold (NT) was measured using a handheld force meter at six points on the lateral aspect of the limb: before diagnostic anaesthesia (T0), and at 15 (T15) and 30 (T30) minutes post anaesthesia. Paired t-tests were performed and significance was set at p <0.05. In addition, ten cadaveric limbs were injected with 2.5 ml new methylene blue solution using a single injection technique to evaluate the extent of dye diffusion within the proximal metatarsal region.Results: Compared with T0, there was a significant decrease in NT for all points combined at T15 (p = 0.008) and also at T30 (p = 0.007). There was a significant decrease in NT at T15 on the lateral third metatarsal bone (p = 0.012). At T30 there was a significant decrease in NT at the lateral sesamoid (p = 0.007), lateral third metatarsal bone (p = 0.031), and mid metatarsus (p = 0.033). Four out of 20 horses had a NT greater than 10 N at the lateral heel bulb at T30. In the cadaveric limbs, the total diffusion distance for all limbs (mean ± SD) was 70.4 ± 20.5 mm. Dye surrounded the DB-LPN in all limbs and the lateral plantar nerve (LPN) in nine out of 10 limbs.Clinical significance: Concurrent anaesthesia of the LPN is likely to occur when DBLPN anaesthesia is performed using a single injection technique.
