    This is our initial report on the first 4 cases of infra-renal abdominal aortic aneurysm undergoing Endovascular Aneurysm Repair (EVAR) with local anaesthesia, controlled sedation and monitoring by an anaesthetist. All four patients were males with a mean age of 66.7 years. Only one required ICU stay of two days for cardiac monitoring due to bradycardia and transient hypotension post procedure. No mortality or major post operative morbidity was recorded and the mean hospital stay post procedure was 3.5 days (range 2-5 days).

    Two recent cases of central retinal artery occlusion under otherwise uncomplicated sub-Tenon's block that resulted in significant visual loss after cataract surgery prompted us to undertake a literature review of such cases. We identified 97 cases of retinal artery occlusion after ophthalmic surgery under regional anaesthesia that had no immediate signs of block-related complications. These occurred after various intraocular (87%) and extraocular (13%) operations, across a wide range of ages (19-89 years) on patients with (59%) or without (39%) known risk factors. The anaesthetic techniques included 40 retrobulbar blocks, 36 peribulbar blocks, 19 sub-Tenon's blocks, one topical anaesthetic and one unspecified local anaesthetic. Different strengths of lidocaine, bupivacaine, mepivacaine and ropivacaine, either alone or in various combinations, were used. The details of the anaesthetic techniques were often incomplete in the reports, which made comparison and analysis difficult. Only nine cases had their cause (optic nerve sheath injury) identified, while the mechanism of injury was unclear in the remaining patients. Various mechanisms were postulated; however, the cause was likely to be multifactorial due to patient, surgical and anaesthetic risk factors, especially in those with compromised retinal circulation. As there were no definite risk factors identified, no specific recommendations could be made to avoid this devastating outcome. We have provided rationales for some general considerations, which may reduce this risk, and propose anaesthetic options for ophthalmic surgery on the fellow eye if required, based both on our literature review and our personal experience.

    Ocular hypotony can occur from many causes, including eye trauma, ophthalmic surgery and ophthalmic regional anaesthesia-related complications. Some of these patients require surgical intervention(s) necessitating repeat anaesthesia. While surgical management of these patients is well described in the literature, the anaesthetic management is seldom discussed. The hypotonous eye may also have altered globe anatomy, meaning that the usual ocular proprioceptive feedbacks during regional ophthalmic block may be altered or lost, leading to higher risk of inadvertent globe injury. In an 'open globe' there is a risk of sight-threatening expulsive choroidal haemorrhage as a consequence of ophthalmic block or general anaesthesia. This narrative review describes the physiology of aqueous humour, the risk factors associated with ophthalmic regional anaesthesia-related ocular hypotony, the surgical management, and a special emphasis on anaesthetic management. Traumatic hypotony usually requires urgent surgical repair, whereas iatrogenic hypotony may be less urgent, with many cases scheduled as elective procedures. There is no universal best anaesthetic technique. Topical anaesthesia and regional ophthalmic block, with some technique modifications, are suitable in many mild-to-moderate cases, whilst general anaesthesia may be required for complex and longer procedures, and severely distorted globes.

    Student-to-student administration of local anesthesia (LA) has been widely used as the teaching modality to train preclinical dental students. However, studies assessing students' outlook towards their first injection were limited. Therefore, this study aims to evaluate students' perception and anxiety levels towards their first LA injection.

    A 68 year old man with significant cardiorespiratory risks factors presented with a ruptured thoracic aortic aneurysm (TAA). This was treated by emergency thoracic endovascular aneurysm repair (TEVAR) under general anaesthesia (GA). An incidental abdominal aortic aneurysm (AAA) was not treated. Eight months later, he presented with ruptured AAA. Due to the patient's compromised respiratory system, he underwent endovascular aneurysm repair (EVAR) under local anaesthesia (LA). He had a smoother post-operation recovery compared to the first repair under GA.

    Background: Dental anxiety is one of the prime reasons for discouraging children to receive dental treatment. Measurement of the dental anxiety is very useful to know the prevalence level among 6- to 12-year-old children. Thus, the aim of the study was to determine the dental anxiety among 6- to 12-year-old children using Modified Dental Anxiety Scale (MDAS) score.

    Materials and Methods: A total of 400 south Indian children in the age group of 6-12 years who had visited Dental College and Hospital were recruited in the study. Dental anxiety was measured before dental treatment using MDAS. Statistical analysis was performed using Wilcoxon signed rank test.

    Results: Of the 400 children, 240 (61.5%) had severe dental anxiety, 92 (23%) had mild anxiety, and 78 (17%) had no anxiety. Females had higher anxiety level compared to males. Many study subjects answered that local anesthesia (LA) injection was considered most fearful. Dental anxiety was highest in smaller age groups.

    Conclusion: In our research, high percentage of children had dental anxiety, so counseling before dental visits is very important to reduce the dental anxiety among these 6- to 12-year-old children.

    A snapping tendon on the dorsal aspect of the thumb is a rare condition as opposed to the common triggering on the volar aspect of the thumb. This condition is known as triggering of the extensor pollicis longus (EPL). A 21-year-old female presented with a clicking or snapping sensation that was felt on the dorsum of her thumb when it is extended. There was no history of trauma. She worked in an ice-cream parlor with repetitive scooping ice-cream motions. Her triggering immediately resolved on releasing the EPL fascia ulnar to Lister's tubercle. Upon wake-up surgery, we could immediately confirm this. We recommend dynamic ultrasound as an investigation and do not recommend MRI. The surgical method of choice is either wake-up surgery or wide-awake local anesthesia no tourniquet (WALANT) surgery.

    This case report presents a combined surgical – orthodontic approach to the management of an unerupted maxillary right permanent central incisor in a 13 year-old Chinese male. Radiographic investigations revealed that the tooth was severely dilacerated, most likely as a result of trauma sustained to the upper maxillary right deciduous central incisor at the age of 3 years. After securing adequate space for the unerupted tooth by fixed appliance therapy, surgical exposure of the crown was carried out under local anaesthesia and oral sedation.
    A gold chain was bonded to the exposed crown of the tooth. Traction was then carried out and the tooth was successfully brought to its final and correct position in the arch after 36 months of active orthodontic treatment.

    Tracheocutaneous fistula (TCF) is a known complication of tracheostomy. It can cause problems such as saliva leak, predispose to infection from external skin into respiratory tract and cosmetically not acceptable. Treatment of the underlying infection is paramount important. Persistence of tract after sufficient duration of observation period should be surgically treated. Cases reported in the literature are mainly regarding paediatric TCF and the procedures are usually done under general anesthesia. We describe a case of surgical treatment of an adult TCF which was done under local anaesthesia.

    Isolated fractures of shaft of ulna are common. Plate fixation with anatomic reduction is thought to produce the best functional results in closed or open fractures. Surgery can be done under general and various types of regional anaesthesia. We report a case of fracture shaft of ulna treated by plating under a combination of WALANT (wide awake, local anaesthesia, no tourniquet) using tumescent anaesthesia and periosteal nerve block as a day care procedure.

    A foreign body (FB) in the upper aerodigestive tract is a common clinical problem that presents as as acute emergency. Sharp FB, such as fish bone or chicken bone, commonly lodges in the tonsil, base of tongue, vallecula or pyriform fossa. Dislodgement of a FB into the laryngopharynx is very rare and specifically onto the vocal cord is extremely uncommon. This case report illustrates a rare case of a sharp FB that was dislodged into the airway and stuck on to the right vocal cord, which was removed under local anaesthesia.

    Background: This study aimed to measure the least initial and maintenance forces of syringe and needle combinations to provide a reference for local anesthetic injection.

    Methods: An experimental study was conducted in our Physics Laboratory during September 2015. A series of syringes sized 1 mL, 3 mL, 5 mL, 10 mL and 20 mL were paired with the original needles, 27G, 27G spinal and 30G. Each combination was tested three times using a compression testing Instron 5940 Series to measure initial and maintenance forces. Statistical analysis was performed using One-way ANOVA.

    Results: The lowest initial force was shown by the combination of 1 mL syringe and 27G spinal needle. However, the 1 mL syringe showed no significant difference across the needles [F(3, 8) = 3.545; P < 0.068]. The original and 27G needle showed mean difference 0.28 (95%CI: -0.19, 0.75; P = 0.420). The lowest maintenance force was measured in the combination of 1 mL syringe and its original 26G needle. On the contrary, both the highest initial and maintenance forces were shown by the combination of 10 mL syringe and 30G needle.

    Conclusion: The 1 mL syringe with original 26G needle shows the best combination.

    Renal hyperparathyroidism with attendant osteodystrophy is a frequent and severe morbidity affecting the quality of life of end stage renal failure patients surviving on long-term renal replacement therapy. A small subgroup of these patients with severe cardiorespiratory dysfunction was deemed at very high risk for general anaesthesia (GA). We report on a series of total parathyroidectomy under local anaesthesia (LA) for these patients.
