Peribulbar versus retrobulbar anaesthesia for cataract surgery

Abstract

Acceptability of blocks Study population RR 1.01 (0.98 to 1.03) 600 (2 studies) ⊕⊕⊕ moderate 3 968 per 1000 978 per 1000 (949 to 997) Medium risk population 965 per 1000 975 per 1000 (946 to 994) *The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; RR: Risk ratio; GRADE Working Group grades of evidence High quality: Further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: We are very uncertain about the estimate. on a scale of 0 to 4 Sequence generation and allocation concealment was inadequate Allocation concealment and sequence generation not clear Allocation concealment and masking was not adequate in 2 of the four trials Sequence generation not clear 5 Peribulbar versus retrobulbar anaesthesia for cataract surgery (Review)

Retrobulbar and peribulbar regional techniques in cats: a preliminary study in cadavers

“…; Alhassan et al. ). This can be explained by the fact that there is no intermuscular membrane separating the extraconal and intraconal spaces, so that they form a contiguous space for spreading of local anesthetic (Ripart et al.…”

“…; Alhassan et al. ). Although PBA is thought to be associated with fewer serious complications, a larger injection volume is required to perform PBA, and this is believed to explain the greater chemosis seen following PBA compared with RBA (Malik et al.…”

“…Both approaches, however, may have potentially sight and life‐threatening complications (Alhassan et al. ).…”

Effect of Addition of Fentanyl and Clonidine to Local Anesthetic Solution in Peribulbar Block

“…[345] But sometimes, it may cause serious complications such as globe perforation, brainstem anesthesia, and retrobulbar hemorrhage. Peribulbar block is a rapid, simple and safe technique but requires larger volume of local anesthetic solution to produce the desired akinesia.…”

The effect of post-traumatic-stress-disorder on intra-operative analgesia in a veteran population during cataract procedures carried out using retrobulbar or topical anesthesia: a retrospective study

“…Several randomized control trials found no difference between RBB and topical [18–20]. A meta-analysis found no significant differences between RBB vs. PBB (Table 1) [21]. …”
