Filter by:Circumcision is one of the most commonly performed operations in the pediatric population and is a painful procedure. Circumcision is performed with two popular techniques, Plastibell and conventional dissection method (CDM). For intra-operative (OP) and post-OP pain relief, two commonly used local anesthetic techniques are caudal block (CB) and dorsal penile block (DPNB) plus ring block (RB) at the base of the penis. There are very few randomized controlled trials comparing these two methods of intra-OP and post-OP pain relief, for different surgical techniques and there is a lack of well-conducted studies comparing the quality of analgesia, need for rescue analgesia in the early post-OP period, complications, and parental satisfaction comparing these blocks. Furthermore, there is a lot of contradiction in the literature regarding the duration of analgesia produced with these techniques.
The purposes of this study are twofold: 1) to assess the effect of a cervical sympathetic block on cerebral blood flow in patients suffering from cerebral vasospasm, after aneurysmal subarachnoid hemorrhage; 2) to evaluate the effect of the sympathetic block on the recovery of the neurological function.
By means of an investigator-initiated, monocentric, single-blinded, prospective, randomized controlled superiority trial, the effect of virtual reality (VR) therapy on patients undergoing ambulatory hand surgery under ultrasound-guided regional nerve block will be investigated. It is hypothesized that the usage of VR during the placement of the nerve block in ambulatory hand surgery patients provides a significant decrease in pain score during anesthesia compared to without VR glasses. Additionally, an objective stress related parameter (HRV), anxiety, VR experience (immersion and presence), adverse effects and patient satisfaction are evaluated before anesthesia, during anesthesia and surgery or after surgery through validated questionnaires or measurements.
The goal of this project is to use a previously described scoring system - the CIA system - as a teaching tool to help learners assess the bleeding risk of peripheral nerve blocks. We will teach the CIA system to residents, then they will complete a survey in which they apply the system to various peripheral nerve blocks. We hypothesize that the CIA system will allow learners to reach the same consensus about bleeding risk as expert opinions.
The aim of this study is to compare between active distraction (video game) and passive distraction (cartoon video) using a Virtual Reality ( VR ) device, in reducing injection pain and anxiety associated with local anesthesia in children.
Dental extraction is the most common procedure undertaken in the department of Oral Surgery, inferior alveolar nerve block (IANB), till today, is the most commonly used local anaesthesia technique for extraction of lower posterior teeth. The anatomical complexity of this technique carries the risk of anaesthetic failures necessitating repeated needle penetrations and hence a painful experience for the patient. In addition, IANB technique, many times, becomes impossible to perform in fearful adult and paediatric patients, those with restricted mouth opening or intellectual disability. Certain coagulation defects are a contraindication to administration of IANB due to its depth of penetration into the tissues that may lead to fatal consequences in case of uncontrolled bleeding. Because of these shortcomings of IANB, there is always a need for alternative anaesthesia techniques that are less painful and carry lesser risks. Anaesthetic injection into the Periodontal ligament space (space between tooth root surface and the bone forming the socket wall) as an alternative to IANB have been tested by many researchers with varying results. The expected advantages of this technique are reduced pain on injection, shorter duration of anaesthesia that prevents inadvertent lips and cheek biting after completion of the procedure. It is expected to be easier to perform in cases of restricted mouth opening and uncooperative patients due to any reason and carry lesser risk of bleeding within tissues. The objective of our study is to evaluate the efficacy of Intra-ligamentary injection for posterior mandibular molar extraction as an alternative to inferior alveolar nerve block (IANB) so that it can be used in cases where IANB is either difficult to perform or not indicated.
This study aimed to compare the effects of mandibular and intraligamentary anesthesia techniques on pain scores during restorative treatment of permanent mandibular molars in pediatric patients. Additionally, comparing the anesthesia techniques in terms of injection pain, the success of anesthesia, postoperative complications, and the subjects' preference was planned. This randomized, controlled, cross-over, single-blind, split-mouth study was conducted on 78 subjects aged 6 to 12 years. Subjects with enamel-dentin caries on the bilateral permanent mandibular molar were included.
This is a randomized, double-blind, single-center clinical trial comparing normal saline and bacteriostatic saline subcutaneous injection within a single subject. While both normal saline and bacteriostatic saline can be administered intravenously, this study aims to investigate their effects following subcutaneous injection. While benzyl alcohol (the bacteriostatic component of bacteriostatic saline) is known to have local anesthetic properties, it also is an irritant and can cause inflammation at the injection site. Based on clinical experience investigators anticipate that a normal saline injection will cause a mild stinging sensation and no subsequent inflammation. In contrast, subcutaneous injection of bacteriostatic saline will not cause stinging but will cause a mild degree of inflammation which is manifested as mild tenderness and mild ecchymosis at the site of injection.
Patients undergoing ACL repair with hamstring autograft frequently develop significant post operative pain at the hamstring grafting site. This pain is within the distribution of a commonly used regional nerve block, the Interspace between the popliteal artery and capsule of the knee (iPACK). The investigators plan to randomize consenting patients to either receiving a SHAM injection of normal saline or to an interventional group of long acting local anesthetic (Ropivacaine) injected in the popliteal fossa between the popliteal artery and capsule of the knee (iPACK). Both groups of patients will receive standard of care with respect to perioperative pain management, which includes a preoperative adductor canal nerve block and preoperative acetaminophen administration. Dual primary endpoints of postoperative pain scores and mean postoperative opioid use will be retrieved and compared between groups. Additional secondary endpoints will be PACU length of stay, PACU opioid use, POD1 opioids use, and POD1 pain scores (best, worst, average).
This study adopts the null hypothesis (There is no difference in pain perception during local anesthesia injection with the buzzy device in comparison to the conventional technique).
