Anaesthetic Management in Cataract Surgery

Persistent opioid use in cataract surgery pain management and the role of nonopioid alternatives

“…58 Although cataract surgery was not explicitly included in this analysis, one could surmise that phacoemulsification is a relatively low pain procedure, and opioids, if prescribed postsurgically, may go unused, thereby increasing the risk for diversion into the community. 33,34,36 ; duration of action ∼30 to 60 min 33,36 and half-life of 2-7 h 22 ; no antianxiety and antiamnesia effects; quick passage across the blood-brain barrier 34 ; emetic and depressive effects may be present postoperatively 37…”

Efficacy of Peribulbar Anaesthesia Versus Topical With Intracameral Lignocaine Anaesthesia in Manual Small Incision Cataract Surgery: A 1-Year Randomised Controlled Trial

“…Blepharospasm was seen in 1 (1.66%) patient in group one and in 5(8.33%) patients in group two which was statistically not significant (p=0.209 into peribulbar block. 5 The occurrence of rare but sightthreatening complications have led to the adoption of the technique of subtenon's block, which avoids the use of sharp needles. Advantages are reduction of complication rates mainly in myopic eyes and the option of re-injections to top up the anaesthesia during surgery.…”

“…Anaesthetic leakage, need for dissection and sutures are its limitations. 5 Topical procedures do not cause akinesia which is the main disadvantage. This can make operating conditions difficult specially in MSICS.…”

Tracheal sound analysis for automatic detection of respiratory depression in adult patients during cataract surgery under sedation

“…[ 1 ] Hence, many anesthesiologists prefer to use stronger sedative techniques,[ 2 ] which increases adverse cardiorespiratory complications. [ 2 ] Since the airway is not sufficiently protected during sedation analgesia, these patients have an increased risk of severe respiratory depression and obstruction,[ 3 ] which necessitates close and continuous monitoring of airway patency and adequacy throughout the period of sedation. Commonly used monitoring techniques such as pulse oximetry usually have a considerable delay in detecting respiratory complications.…”
