ABSTRACT
Clinical Information Patient Initials or Identifier Number: A Relevant Clinical History and Physical Exam: 47yr old man, suffered a blast injury at the workplace after an O2 tank exploded while he was transferring liquid gas into a tank for welding purposes. The impact has caused him to temporary loss of consciousness. Upon awakening, he had severe chest pain associated with shortness of breath. On examination, superficial partial thickness injury on the chest wall, and lungs: reduced breath sound bi-basally, no murmur heard. BP:106/77mmHg, HR:100/min, SPO2 100% on HFM 15L/min. [Formula presented] [Formula presented] [Formula presented] Relevant Test Results Prior to Catheterization: Serial ECGs were done and showed dynamic changes in the anterior leads Bedside echo before invasive coronary angiograms shows mild LVSD, normal valves, and no pericardial effusion [Formula presented] [Formula presented] Relevant Catheterization Findings: Right radial approach 6F system Opitorque catheter for diagnostic angiogram LMS: smooth LAD: ATO mid LAD, DG1 prox ATO LCx: smooth RCA: smooth Impression: ATO to LAD and Diagonal 1 ( Dual ATO) [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: Right radial coronary angiogram via 6F system EBU 3.0 engaged with good support Sion blue wired into LAD, export catheter delivered, and aspirated red thrombus Pre-dilated with Sapphire 3 SC 2.5x15mm @ 6-10ATM Flow established in LAD, however, decided to interrogate DG1 as it shows ATO BMW wired into the DG1 and pre-dilated with Sapphire 3 SC 2.0x15mm Noted nonflow limiting dissection and decided to stent DG1 with 2.25x34mm@12ATM, dissection sealed and TIMI III flow established Stented mid LAD with 2.5x30mm @12ATM just before LAD/DG1 bifurcation, then stented proximal LAD with 2.5x 26mm@ 12ATM. Post-dilated LAD with 2.75x15mm@ 14-20ATM TIMI II-III flow IV Tirofiban has been given a loading dose due to a high thrombus burden and sluggish flow [Formula presented] [Formula presented] [Formula presented] Conclusion(s): Myocardial infarction is a rare complication of blunt chest trauma. This case demonstrates how blast shock waves result in the dissection of the coronary vessel leading to total occlusion of the two vessels. It also promotes red thrombus within the coronary vessels. Percutaneous coronary intervention is the most suitable way to treat this condition. Intravascular imaging such as IVUS or OCT would be beneficial to demonstrate the physiology behind this MI and would also be helpful in planning and optimizing the lesions. Unfortunately, intravascular imaging was not used for this patient to reduce procedural time as he was treated during the height of the COVID pandemic.Copyright © 2023
ABSTRACT
Background: Trauma is one of the leading causes of deaths worldwide for all age groups, especially in the younger age group. The purpose of the current study is to assess/analyze the factors for mortality in penetrating abdominal traumas with respect to the total number of intra-abdominal organs injured, related extra-abdominal injuries, gender, type of injury, time of arrival, and amount of blood transfusion needed during the pandemic. Methods: A retrospective study including 523 patients underwent laparotomy in Al-Emamien Al-Kadhimin Medical City from March 2020 to September 2021 for a penetrating abdominal injury due to blast injury, bullet, shrapnel injury, and stab wounds. The study population with penetrating abdominal traumas and indicative abdominal signs was subjected to exploratory laparotomy. Results: In this study, 465 (88.9%) males and 58 (11.1%) females participated;the highest rate was found in small bowel injuries (40.73%) followed by large bowel injuries (21.99%), whereas the lowest rate was found in gallbladder injury (1.34%). Chest injuries represent the highest rate among extra-abdominal injuries (18.36%), whereas head and neck represent the lowest rate (1.34%). Regarding the risk factors affecting the mortality rate, the highest rate of mortality was found in the case of gunshot (13.11%), followed by shrapnel (6.38%) and stab wound injuries (5.26%), which was the lowest. Conclusion: Penetrating abdominal injuries were the most common among males, small bowel injuries are the commonest organs affected by the penetrating abdominal injuries, shrapnel injuries were the commonest causes in our country, and the highest mortality rate was related to gunshot and number of organs affected and delay of arrival to the hospital and number of pints of blood received.
ABSTRACT
The majority of firework-related injuries in Germany are found at the turn of the year. With regard to hearing, a distinction is made between blast (BT) and explosion trauma (ET). The study examines the prevalence and characteristics of firework-related injuries over the past 11 years on New Year's Eve and compares these with the effects of the pyro ban 2020/21 imposed due to the COVID-19 pandemic. A retrospective chart review of all patients who presented themselves with the diagnosis blast trauma (H 83.3) or explosion trauma (T 70.8) at the Charité emergency service in the last 11 years from December 28 to January 5 was performed. 267 patients were recorded (78 % male). 1/3 each were assigned to the age group 10-19 and 20-29 years. 21 % of the patients were admitted to the hospital. There was an isolated BT of the ear in 66 %, hand injuries in 12 %, head injuries in 8 % and eye injuries in 4 %. 87 % had ear involvement with hearing loss: 83 % with tinnitus, 5.6 % with ET. The tone audiograms of BT and ET show differences only at 6 kHz, but not at 4 kHz. 8.6 % of the patients underwent surgical interventions. The treatment of a tympanic membrane perforation was carried out by: 54 % splinting vs. 38 % tympanoplasty. Therapy with a glucocorticoid was administered i.v. in 48 % and initiated orally in 17 %. Overall, there was a decrease in injuries of almost 90 % in 2020/21 compared to 2017/18. The use of fireworks leads to increased utilization of health care resources. The ban on the sale of pyrotechnics as well as the introduction of pyro ban zones in 2020 led to a relevant decrease in injuries. 2020 was the only year in which there were no injuries in children / adolescents. The BT of the ear is the most common firework-related injury.
ABSTRACT
A flap is done to cover expose structures such as bone, tendon and ligament. Chest wall flaps are usually performed under general anaesthesia due to a fairly large area of surgery and at two different sites which are the chest and the hand. This is the first known reported case of a chest wall flap for coverage of the hand under Wide awake local anaesthesia no tourniquet technique (WALANT). We here report the case of a 32-year-old man who had a firecracker injury over his right hand with bone exposed in his right index and middle finger and distal amputation of the thumb with first carpometacarpal joint dislocation. Chest wall flap reconstruction for coverage of a severe blast injury in the hand is possible and safe under WALANT. The proper technique and administration will lead to a successful surgery without general anesthesia complications and risks. This alternative option may be useful in districts or smaller hospitals where resources are limited.
