Longitudinal and axial approaches were used for globe imaging and to obtain axial length respectively purchase 50mg zoloft otc depression symptoms breathing. They used 25 mm long 23 G needle zoloft 25mg without a prescription depression news, which was attached to an extension to inject the drug (6 mL of 0 buy zoloft 100mg without prescription mood disorder hospitals. Long axis approach was used and needle was introduced till the needle tip was 2 mm away from the optic nerve order 25 mg zoloft amex depression supplements. In sub-Tenon’s group, spread of local anesthetic solution was on both sides of optic nerve into the sub-Tenon’s space with a characteristic T-sign. In the peribulbar group, local anesthetic solution spreads in the peribulbar, retrobulbar and sub-Tenon’s space with similar T-sign. There are many concerns regarding the safety of the use of ultrasonic energy to the eye while performing ultrasound for ophthalmic block. So normal transducer used for peripheral nerve blocks may not be suitable for ophthalmic blocks. Specific orbital-rated transducer with decreased mechanical and thermal index should be used as nonorbital-rated transducers 234 Yearbook of Anesthesiology-6 leads to mechanical and thermal changes in the eye. Other drawbacks of ultrasound are requirement of more time for performing the block, discomfort to the patient due to pressure of the transducer on the eye, need for assistant to inject the drug or to hold the transducer and difficulty in recognizing the finer needle. Peribulbar or retrobulbar anesthesia has been associated with numerous ocular complications including diplopia, orbital hemorrhage, globe perforation, central retinal vein or artery occlusion, brainstem anesthesia, optic nerve trauma and ptosis. Many patients experienced pain of needle injection and intravenous sedation during injection. Local anesthetic is deposited into the sub-Tenon’s space, which blocks the short ciliary nerves. Akinesia occurs due to direct blockade of the anterior motor fibers when they enter into the extraocular muscles. Local anesthetic surrounds the optic nerve and diffuses into the retrobulbar space thus affecting he vision of the patient. But inferonasal quadrant, which is most commonly used as distribution of drug, is better and it avoids surgical area and damage of vortex veins. Many types of long and short cannulas (metal, silicon, plastic) are available for the block but a metal, 19 G, 2. The eye is draped and patient is asked to look upward and outward to expose inferonasal quadrant. At 5–7 mm away from limbus, conjunctiva and Tenon’s capsule are gripped with non-toothed forceps. Sub-Tenon’s cannula attached to the syringe filled with local anesthetic solution is inserted. Cannula follows the curvature of the globe and drug is injected after negative aspiration. About 3–5 mL drug is administered for anterior segment surgery and 7–10 mL drug is injected for posterior segment surgery. Trabeculectomy and strabismus surgery can also be performed with sub-Tenon’s block. A 20 G plastic intravenous cannula can also be used through sub-Tenon’s route, it provides similar operating conditions, akinesia and analgesia like metal cannula. Major complications associated with the block include orbital and retrobulbar hemorrhage, rectus muscle paresis and trauma, globe perforation, the central spread of local anesthetic and orbital cellulitis. However, cataract surgery can be performed without hyaluronidase with similar patient comfort and surgeon satisfaction. They suggested that due to mild redness, sub-Tenon’s block should not be deferred considering its benefit. These patients had minor subconjunctival hemorrhages, which were more than in the control group. They concluded that anticoagulants may be safely continued in patients for phacoemulsification under sub-Tenon’s block. Sub-Tenon’s block has been used in children undergoing strabismus surgery, vitreoretinal surgery and cataract surgery under general anesthesia. In conclusion, sub-Tenon’s block is safer than other needle blocks and provides equally effective analgesia and akinesia with lesser volume of local anesthetic drug. It can be administered in patients on anticoagulants without major hemorrhagic complications and can be safely administered in children under general anesthesia. In ophthalmic surgery, propofol, midazolam and propofol-ketamine combination has been used frequently for sedation. Recently dexmedetomidine has been used for sedation during ophthalmic surgery under regional anesthesia. It was noticed that though, both drugs provided similar sedation, ketofol has advantage of rapid onset and shorter recovery without adverse effects on respiration. It was found that dexmedetomidine reduces minimum local anesthetic concentration of ropivacaine, with reduction in postoperative analgesic requirement without causing any neurological side effects. On the other hand, there is also risk of bleeding during regional ophthalmic blocks and surgery with continuation of these drugs. Update on Anesthesia for Ophthalmic Surgery 237 Newer antiplatelet and anticoagulant have different pharmacodynamics and pharmacokinetics. So, the effects of these drugs on regional ophthalmic blocks and surgery will be different with different risk for bleeding. Thienopyridine derivative include clopidogrel, ticlopidine and newer prasugrel, ticagrelor. Platelet dysfunction persists from 5 to 7 days after stopping the clopidogrel and 10–14 days after ticlopidine. Half- life of dabigatran after a single dose is 8 hours and after multiple dose 17 hours. Surgeon and anesthesiologist should decide regarding continuation or stopping these drugs for ophthalmic blocks and surgery on individual case basis after consulting the treating cardiologist and patient with the discussion of risk of a thromboembolic event versus. If patient is having high risk of thromboembolic event such as recent stent insertion then antiplatelet should be continued. In trabeculectomy, aspirin can be continued safely but warfarin increases the risk of serious bleeding with risk of failure of surgery. Even with aspirin, risk of hyphema is increased after surgery but it does not affect surgical outcome. Therefore, decision should be taken judiciously weighing sight threatening complications with life-threatening complications. Sub-Tenon’s block is a safe block and provide similar akinesia and anesthesia in comparison to peribulbar block. It can be administered in patients on anticoagulants without major hemorrhagic complications. Oculoplasty and glaucoma surgery and vitreoretinal surgery are more prone for hemorrhagic complications with continuation of these drugs.

Narouze Clinical Presentation and Physical Examination The most common symptom with pain stemming from the C2–C3 facet joint is unilateral pain overlying the joint with C2–C3 little suboccipital/occipital radiation. Upper cervical spine rotation and extension are usually painful and limited and can reproduce the pain. Imaging Plain radiography of the cervical spine will show the degen- erative changes and may exclude tumor or fracture. With progressing age, degenerative cervical spine changes are more frequently seen: 25 % at the age of 50 up to 75 % at the age of 70 [10]. Degenerative changes of the cervical spinal can be found in asymptomatic patients, indicating that degenerative changes do not always cause pain. Some authors claim that 100 % pain the judicious utilization of interventional pain management relief should be achieved. In daily clinical practice, we consider responsive to conservative therapy and with evidence of a diagnostic block successful if more than 50 % pain reduc- C2–C3 joint involvement by examination and imaging.

In a group of transverse plane at the upper cervical level and assuming a more vertical position at the upper thoracic level. Articular branches may also arise from a communicating loop that crosses the back of the joint between the third occipital nerve and the C2 dorsal ramus [8 , 9]. Beyond the C2–C3 zygapophyseal joint, the third occipital nerve becomes cutaneous over the suboccipi- tal region. Therefore, pain derived from the C2–C3 zygapophy- seal joint can be addressed by blocking the ipsilateral third occipital nerve as it crosses the lateral aspect of the joint, and pain derived from joints below C2–C3 can be addressed by blocking the cervical medial branches as they pass around Vertebral the waists of the articular pillars above and below the cor- artery responding joint [9 ].
