Project description:BACKGROUND:We evaluated severe pain-related adverse events (SAE) during the percutaneous dilatational tracheostomy (PDT) procedure performed by a neurointensivist and compared the outcomes with that of conventional surgical tracheostomy in neurocritically ill patients. METHODS:This was a retrospective and observational study of adult patients who were admitted to the neurosurgical intensive care unit between January 2014 and March 2018 and underwent tracheostomy. In this study, primary endpoints were incidence of SAE: cardiac arrest, arrhythmias, hypertension, hypotension, desaturation, bradypnea, or ventilatory distress. The secondary endpoint was procedure-induced complications. RESULTS:A total of 156 patients underwent tracheostomy during the study. Elective surgery of brain tumors (34.0%) and intracranial hemorrhage (20.5%) were the most common reasons for admission. The most common reasons for tracheostomy were difficult ventilator weaning or prolonged intubation (42.9%) and sedative reduction (23.7%). Tachycardia (30.1%) and hypertension (30.1%) were the most common SAE. Incidence of SAE was more common in conventional tracheostomy compared to PDT (67.1% vs. 42.3%, P?=?0.002). The total duration of SAE (19.8?±?23.0?min vs. 3.4?±?5.3?min, P?<?0.001) and procedural time (42.2?±?21.8?min vs. 17.7?±?9.2?min, P?<?0.001) were longer in conventional tracheostomy compared to PDT. Multivariable adjustment revealed that only PDT by a neurointensivist significantly reduced the incidence of SAE by one third (adjusted odds ratio [OR]: 0.36, 95% confidence interval [CI]: 0.187-0.691). In addition, PDT by a neurointensivist deceased the duration of SAE by 8.64?min (?: -8.64, 95% CI: -?15.070 - -2.205, P?=?0.009) and prolonging the procedure time by every one minute significantly increased the duration of SAE by 6.38?min (?: 6.38, 95% CI: 0.166-0.470, P?<?0.001). Procedure-induced complications were more common in conventional tracheostomy compared to PDT (23.5% vs. 11.3%, P?=?0.047). CONCLUSIONS:This retrospective and exploratory study of our single-center limited cohort of tracheostomy patients revealed that decreased SAE may be associated with short procedural time during the PDT procedure performed by a neurointensivist. It is proposed that PDT by a neurointensivist may be safe and feasible in neurocritically ill patients.

Project description:PURPOSE:Emergent tracheostomy under local anaesthesia is a reliable method of airway management when orotracheal intubation is not possible. COVID-19 is spread through aerosol making the emergent tracheostomy a high-risk procedure for surgeons. The surgical establishment of the air conduit in emergency scenarios must be adjusted for safety reasons. METHODS:To establish the Slovenian National Guidelines for airway management in cannot intubate-cannot ventilate situations in COVID-19 positive patients. RESULTS:Good communication and coordination between surgeon and anaesthesiologist is absolutely necessary. Deep general anaesthesia, full muscle relaxation and adequate preoxygenation without intubation are initial steps. The surgical cricothyrotomy is performed quickly, the thin orotracheal tube is inserted, the cuff is inflated and ventilation begins. Following patient stabilisation, the conversion to the tracheostomy is undertaken with the following features: skin infiltration with vasoconstrictor, a vertical incision, avoidance of electrical devices in favour of classical manners of haemostasis, the advancement of the tube towards the carina, performing the tracheal window in complete apnoea following adequate oxygenation, the insertion of non-fenestrated canulla attached to a heat and moisture exchanger, the fixation of canulla with stitches and tapes, and the cricothyrotomy entrance closure. Appropriate safety equipment is equally important. CONCLUSION:The goal of the guidelines is to make the procedure safer for medical teams, without harming the patients. Further improvements of the guidelines will surely appear as COVID-19 is a new entity and there is not yet much experience in handling it.

Project description:ObjectiveThe aim of this case series was to demonstrate that surgical tracheostomy can be undertaken safely in critically ill mechanically ventilated patients with coronavirus disease 2019 (COVID-19) and that it is an effective weaning tool.Study designRetrospective case series.SettingSingle academic teaching hospital in London.MethodsAll adult patients admitted to the adult intensive care unit (AICU), diagnosed with severe COVID-19 infection and requiring surgical tracheostomy between the March 10, 2020, and May 1, 2020, were included. Data collection focused upon patient demographics, AICU admission data, tracheostomy-specific data, and clinical outcomes.ResultsTwenty patients with COVID-19 underwent surgical tracheostomy. The main indication for tracheostomy was to assist in respiratory weaning. Patients had undergone mechanical ventilation for a median of 16.5 days prior to surgical tracheostomy. Tracheostomy remained in situ for a median of 12.5 days. Sixty percent of patients were decannulated at the end of the data collection period. There were no serious immediate or short-term complications. Surgical tracheostomy facilitated significant reduction in intravenous sedation at 48 hours after tracheostomy formation. There was no confirmed COVID-19 infection or reported sickness in the operating surgical or anesthetic teams.ConclusionSurgical tracheostomy has been demonstrated to be an effective weaning tool in patients with severe COVID-19 infection.

Project description:Cervicofacial subcutaneous emphysema (SE) is primarily caused by dental treatment introducing gas into the subcutaneous tissue. Air rapidly dissects into the subcutaneous tissue with face and neck swelling, leading to respiratory distress, patient discomfort, and chest pain. Computed tomography (CT) can detect spreading SE patterns. However, the true volume of SE and the degree of air changes in the body over time remain unknown. We evaluated the healing process of SE and the temporal changes in the volume of emphysema in three cases detected using our hospital's electronic health record systems based on inclusion and exclusion criteria over the past 10 years, with CT and three-dimensional (3D) images. The first case was a 46-year-old woman who presented with complaints of swelling from her right eyelid to the neck and clavicles, pain on swallowing, respiratory distress, and hoarseness. The second case was a 35-year-old man who presented with complaints of swelling over the face. The third case was a 36-year-old man who presented with complaints of swelling from the left cheek to the neck. CT revealed SE and pneumomediastinum in all cases. All the patients were administered an antibacterial drug. The CT and 3D images showed an improvement in emphysema 3 days after the onset, with more than half of the volume reduction in emphysema. This made it possible to evaluate the changes in the air content of SE. Observation with CT until the healing process of SE is completed is crucial, and 3D images also help evaluate changes over time.

Project description:Subcutaneous emphysema occurs when air is forced under the tissue, causing swelling, crepitus on palpation, and the possibility of spreading along the fascial planes. Although subcutaneous emphysema secondary to dental procedures is rare, it can be a potentially fatal complication if not diagnosed and treated promptly and correctly. Dentists need to be able to differentiate subcutaneous emphysemas from more common disease processes that have similar clinical presentations. We report a 22-year-old male who underwent mandibular wisdom tooth extraction and subsequently developed extensive subcutaneous emphysema. The patient was quickly taken care of, in partnership with the maxillofacial department. The purpose of this report is to bring attention to the fact that obtaining an accurate diagnosis for this condition is very important and management on time can prevent serious complications.

Project description:Lung volume reduction surgery (LVRS) and bronchoscopic lung volume reduction (bLVR) are palliative treatments aimed at reducing hyperinflation in advanced emphysema. Previous work has evaluated functional improvements and survival advantage for these techniques, although their effects on the micromechanical environment in the lung have yet to be determined. Here, we introduce a computational model to simulate a force-based destruction of elastic networks representing emphysema progression, which we use to track the response to lung volume reduction via LVRS and bLVR. We find that (1) LVRS efficacy can be predicted based on pre-surgical network structure; (2) macroscopic functional improvements following bLVR are related to microscopic changes in mechanical force heterogeneity; and (3) both techniques improve aspects of survival and quality of life influenced by lung compliance, albeit while accelerating disease progression. Our model predictions yield unique insights into the microscopic origins underlying emphysema progression before and after lung volume reduction.

Project description:BackgroundSubcutaneous emphysema and mediastinal emphysema and/or pneumothorax after mechanical ventilation through endotracheal intubation is not uncommon. However, cases of delayed mediastinal emphysema and subcutaneous emphysema after extubation and their further development into pneumothorax have rarely been reported, especially in children. Given this, we provide such a case for the reference of clinicians.Case descriptionWe report a case of a 2-year-old girl with no abnormalities at the preoperative examination, who developed subcutaneous emphysema and mediastinal emphysema 4 hours after recovery from general anesthesia due to ophthalmic arterial infusion chemotherapy for retinoblastoma, and bilateral pneumothorax 12 hours later. The patient recovered and was discharged following aggressive treatment of subcutaneous exhaust and thoracic closed drainage. Due to fiberoptic bronchoscopy was refused by the guardian to determine the cause, we hypothesized tracheal intubation injury occurs, air enter the trachea or bronchial mucosa, extend up to the neck, head and face along the blood vessels, larynx and deep cervical fascia spaces, causing subcutaneous emphysema, and then gradually spread to the mediastinum, resulting in mediastinal emphysema and pneumothorax. However, the etiology and preventive measures warrant further study.ConclusionsStrengthen the etiological study of subcutaneous and/or mediastinal emphysema and pneumothorax due to endotracheal intubation, perioperative observation and postoperative follow-up are important measures for the effective prevention, early diagnosis, and timely treatment of subcutaneous and/or mediastinal emphysema and pneumothorax, and are also conducive to ensuring the safety of patients.

Project description:INTRODUCTION: Tracheostomy is one of the more commonly performed procedures in critically ill patients yet the optimal method of performing tracheostomies in this population remains to be established. The aim of this study was to systematically review and quantitatively synthesize all randomized clinical trials (RCTs), comparing elective percutaneous dilatational tracheostomy (PDT) and surgical tracheostomy (ST) in adult critically ill patients with regards to major short and long term outcomes. METHODS: MEDLINE, EMBASE, CINAHL and the Cochrane Controlled Clinical Trials Register databases were searched to identify relevant studies. Additionally, bibliographies and selected conference proceedings were reviewed, and experts in the field and manufacturers of two PDT kits were contacted. Randomized clinical trials comparing any method of elective PDT to ST that included critically ill adults and reported at least one clinically relevant outcome were included. Data extracted included trial characteristics, measures of study validity, and clinically relevant outcomes. RESULTS: Seventeen RCTs involving 1,212 patients were included. Most PDTs used a multiple dilator technique and were performed in the intensive care unit (ICU). The pooled odds ratio (OR) for wound infection was 0.28 (95% confidence interval (CI), 0.16 to 0.49, p < 0.0005), indicating a significant reduction with PDT compared to ST. Overall, PDT was equivalent to ST for bleeding, major peri-procedural and long-term complications; however, subgroup analysis suggested PDT resulted in a lower incidence of bleeding (OR = 0.29 (95% CI 0.12 to 0.75, p = 0.01)) and death (OR = 0.71 (95% CI 0.50 to 1.0, p = 0.05)) when the STs were performed in the operating theatre. CONCLUSION: PDT reduces the overall incidence of wound infection and may further reduce clinical relevant bleeding and mortality when compared with ST performed in the operating theatre. PDT, performed in the ICU, should be considered the procedure of choice for performing elective tracheostomies in critically ill adult patients.
