Aim: Study of advantages of retrobulbar anesthesia and its complications in posterior vitrectomy using 0.5% bupivacaine with lidocaine 2% Materials and Methods: Number of study patients: 1000 patients who underwent a retrobulbar anesthesia using a combination of 4 ml bupivacaine 0.5% + 6 ml lidocaine 2% for a Pars-planaposterior vitrectomy. Results: Patients aged between 16-85 years, 55% of whom were males and 45% females, the indications of the Pars-plana vitrectomy were: 45% diabetic retinopathy, 15% macular hole, 10 lens-luxation , 7% artificial lens dislocation, 5% chorioiditis,5% posttraumatic vitreous haemorrhage , 5% macular pucker, 5% rhegmtogenous retinal detachment, 5% intraocular foreign body, 0.5% endophthalmitis. Complications: 0.4% retrobulbar hemorrhage, 2% elevated intraocular pressure, 0.2%, expulsive choreoidale haemorrhage, pain 8%, fear, anxietyand tension 0.2%, eyelid haematome 4%, patient movement 1.3% , diplopia 1%, ptosis 1,3%, low heart rate and low arterial pressure 0.3%. Conclusion : retrobulbar anesthesia is recommended with the combination of bupivacain and lidocaine in the posterior vitreorectomy, with some exceptions such as drug allergies, single eye, high myopy, advanced optic nerve lesions, children, no coopertion.

This study was performed to investigate the analgesic effects of lidocaine , Xylazine and Lidocaine / Xylazine combination in eye regional anesthesia. Twenty four goats were randomly designed in 4 groups .
This study was carried out in the department of anesthesia and reanimation at Alassad ,Tishreen university Hospitals , Lattakia , Syria , during the year 2014-2015 , and included 45 patients of either sex (5-15 kilogram of weight ) undergoing lower abdominal and urologic procedures. Patients were divided into three groups : Patients of group A : received spinal anesthesia by using combination between bupivacaine (0.4 mg/kg ) and normasaline (placebo) . Patients of group B : received spinal anesthesia by using combination between bupivacaine (0.4 mg/kg ) and fentanyl (0.2 mcg/kg ) . Patients of group c : received spinal anesthesia by using combination between bupivacaine (0.4 mg/kg ) and fentanyl (0.6 mcg/kg ) . The goal of the study is studying the effects of combination between fentanyl and bupivacaine in the spinal anesthesia for the children whom prepared to subumblical operations . Conclusion : Combination between fentanyl and bupivacaine reduced to use postoperative narcotics and increased the duration of spinal anesthesia, in addition to provided hemodynamic stability during the operation.
In this paper, we describe our proposed methods for the multilingual word-in-Context disambiguation task in SemEval-2021. In this task, systems should determine whether a word that occurs in two different sentences is used with the same meaning or no t. We proposed several methods using a pre-trained BERT model. In two of them, we paraphrased sentences and add them as input to the BERT, and in one of them, we used WordNet to add some extra lexical information. We evaluated our proposed methods on test data in SemEval- 2021 task 2.
Purpose: to assess the efficiency of topical anesthesia in phacoemulsification with IOL implantation. Department of Ophthalmology, Muasaa Hospital. The research was carried on 56 eyes of 48 patients.
Sarcasm detection and sentiment analysis are important tasks in Natural Language Understanding. Sarcasm is a type of expression where the sentiment polarity is flipped by an interfering factor. In this study, we exploited this relationship to enhance both tasks by proposing a multi-task learning approach using a combination of static and contextualised embeddings. Our proposed system achieved the best result in the sarcasm detection subtask.
