A Case of Posterior Tracheal Wall Rupture During Tracheostomy Treated With Sternocleidomastoid Muscle Reinforcement

A posterior tracheal wall rupture is a rare but life-threatening complication of tracheostomy. Several flaps based on the sternocleidomastoid (SCM) muscle, which has sufficient length and abundant blood supply, are utilized for the reconstruction of tracheal defects. We discuss here a case of a 71-year-old male with multiple organ failure and mental retardation, with posterior tracheal wall damage that had occurred during tracheostomy tube insertion. When planning the repair of the wound, additional reinforcement was necessary due to saliva leakage secondary to decreased consciousness. Direct suturing was followed by the reinforcement of SCM muscle transposition, which was conducted through cervical and endoscopic approach.

Percutaneous dilational tracheostomy following anterior cervical spine fixation – a retrospective propensity-matched cohort study

PurposeIn patients with traumatic, infectious, degenerative, and neoplastic surgical indications in the cervical spine, commonly the anterior approach is used. Often these patients require a tracheostomy necessary due to prolonged mechanical ventilation. The limited spinal mobility and proximity to the surgical site of anterior cervical spine fixation (ACSF) could pose an increased risk for complications of percutaneous dilational tracheostomy (PDT.) Importantly, PDT might raise wound infection rates of the cervical spine approach. The aim of this study is to prove safety of PDT after ACSF.MethodsWe performed a retrospective, single-center study comparing patients with and without ACSF who underwent Ciaglia-single step PDT. After propensity score matching using logistic regression, we compared intra- and postprocedural complication rates. Furthermore, surgical site infections were evaluated. Putensen’s definitions of complications and Clavien-Dindo’s classification were used.ResultsA total of 1175 patients underwent PDT between 2009 and 2021. Fifty-seven patients underwent PDT following ACSF and were matched to fifty-seven patients without ACSF. The mean interval between ACSF and PDT was 11.3 days. The overall complication rate was 19.3% in the ACSF group and 21.1% in the non-ACSF group. The mean follow-up was 388 days (± 791) in the ACSF group and 424 days (± 819) in the non-ACSF group. Life-threatening complications (Clavien-Dindo IV to V) were found in 1.8% of ACSF patients and 3.5% of non-ACSF patients. There were no significant differences in complication rates. No surgical site infection of the anterior spine access was detected.ConclusionPDT is a feasible and safe procedure in patients after ACSF. Complication rates are comparable to patients without ACSF. Surgical site infections of ACSF are very rare.

Elective vs. emergency tracheotomy complications in advanced hypopharyngeal cancer.

Squamous cell carcinoma of the hypopharyngeal region is a rare, aggressive disease with a poor prognosis and a high mortality rate, and represents up to 95% of all hypopharyngeal tumors. Patients with upper aerodigestive tract tumors can develop airway compromise before or during chemoradiotherapy. The present study aims to investigate the complication differences between elective tracheostomy and emergency-setting tracheostomy for patients with advanced hypopharyngeal squamous cell. The study group included 36 patients and analyzed the number and type of complications, functional outcomes and comparation of the laboratory testing in all the patients at 3 specific points (before tracheotomy, during the radiation therapy and at least 3 months after completion of radiation therapy). In addition, univariate analysis was performed in order to evaluate the prognosis of local control rates. The type and number of complications between elective and emergency-setting tracheostomy varied, but all the complications were resolved, and no hypoxic complications secondary to displacement of the tracheostomy tube or death cases related to the tracheostomy occurred. A total of 20/36 patients presented with complications, with 73% (16 patients) from the emergency tracheostomy cohort and 36% (4 patients) from the elective tracheostomy group. More than half of the elective tracheostomy (6/11 patients) responded favorably to the treatment, with a higher frequency than the patients with emergency tracheostomy (5/22 patients). The present study did not encounter significant statistical differences (P>0.05) of the treatment end-result regarding the type of tracheostomy performed, but the prediction analysis found for the patients aged under 60 years old, elective tracheostomy was associated with a higher chance of favorable treatment end result.

Impact of ciprofloxacin/dexamethasone on pediatric tracheostomy outcomes

Objective(s)To investigate the effectiveness of ciprofloxacin/dexamethasone in reducing granulation tissue post-tracheostomy in pediatric patients. MethodsThis cohort study examined pediatric patients with a tracheostomy at a single academic institution from 2016 to 2020. Exclusion criteria included: deceased within 1 year (n = 38), >16 years of age (n = 21), decannulated within 1 year (n = 15), lost to follow-up within 1 year (n = 6), and revision tracheostomy (n = 2). Logistic regression or Wilcoxon rank-sum (α = 0.05) were used to compare demographic and clinical characteristics between patients who did and did not receive ciprofloxacin/dexamethasone within 1 year of their tracheostomy. ResultsIn this cohort, (n = 126, median age 5.2 months, 54.0 % male), 62.7 % received ciprofloxacin/dexamethasone within 1 year, with 27.8 % taking the nebulized form. Granulation tissue occurred in 81.0 % of cases, predominantly peristomal (69.8 %) and suprastomal (34.9 %). Notable complications included accidental decannulation (13.6 %), suprastomal collapse (11.2 %), and bleeding (7.2 %). Although granulation tissue was more common in ciprofloxacin/dexamethasone users (92.4 %) versus non-users (61.7 %) (OR: 7.55, 95 % CI: 2.73–20.9, p < 0.001), patients exhibited less frequent granulation tissue events after initiation (z = 3.88, p < 0.001). No significant differences in antibiotic resistance (p = 1.0) or endocrinology complications (p = 0.1) were found between those with and without ciprofloxacin/dexamethasone. ConclusionsWe found a statistically significant reduction of granulation tissue incidence with ciprofloxacin/dexamethasone use and no significant differences in antibiotic resistance or endocrinology complications were noted. Future investigation is warranted to explore timing of ciprofloxacin/dexamethasone administration for granulation tissue and its role in managing and preventing tracheostomy complications.

The effect of narrow band imaging in CO2 laser therapy in early-stage glottic cancer

Objective:To explore efficacy of narrow band imaging（NBI） technique in CO2laser therapy in Early-Stage Glottic cancer. Methods:The clinical data of patients with Early-Stage Glottic cancer who underwent CO2laser vocal cord resection from June 2011 to August 2022 were retrospectively analyzed. Among these, 27 patients who underwent surgery assisted by NBI were assigned to the observation group, while 25 patients who underwent conventional CO2 laser microsurgery with a suspension laryngoscope were assigned to the control group. The differences between the two groups were analyzed in terms of intraoperative frozen pathology results, postoperative recurrence rates, 5-year cumulative disease-free survival rates, complications, and voice recovery. Results:All 52 patients were operated successfully. Temporary tracheostomy and serious complications did not occur during the operation. The postoperative patient's pronunciation was satisfactory. One patient experienced vocal cord adhesion, but there were no severe complications such as breathing difficulties or bleeding, with an overall complication rate of 1.92%. Postoperative follow-up was 1-5 years. The 5 years recurrence free survival in the general group was 77.90％, and the 5 years recurrence free survival in the NBI group was 100％, the difference was statistically significant（P<0.05）. NBI endoscopy is safer and more accurate than the general group in determining the safe margin of tumor mucosal resection（P<0.05）. Among the patients who accepted the voice analysis, the difference was no statistically significant（P>0.05）. Conclusion:Compared with conventional CO2laser surgery under microscope, NBI guided laser resection of Early-Stage Glottic cancer is more accurate. NBI guided laser resection could improve 5 years recurrence free survival rate. In a word, narrow-band imaging endoscopy can has very high value in clinical application.

Benefits of Rib Fixation Utilizing Low-Cost Materials: A Randomized Pilot Trial

IntroductionSurgical stabilization of rib fractures (SSRF) using standard rib plating systems has become a norm in developed countries. However, the procedure has not garnered much interest in low–middle-income countries, primarily because of the cost. MethodsThis was a single-center pilot randomized trial. Patients with severe rib fractures were randomized into two groups: SSRF and nonoperative management. SSRF arm patients underwent surgical fixation in addition to the tenets of nonoperative management. Low-cost materials like stainless steel wires and braided polyester sutures were used for fracture fixation. The primary outcome was to assess the duration of hospital stay. ResultsTwenty-two patients were randomized, 11 in each arm. Per-protocol analysis showed that the SSRF arm had significantly reduced duration of hospital stay (22.6 ± 19.1 d versus 7.9 ± 5.7 d, P value 0.031), serial pain scores at 48 h and 5 d (median score 5, IQR (3-6) versus median score 7, IQR (6.5-8), P value 0.004 at 48 h and median score 2 IQR (2-3) versus median score 7 IQR (4.5-7) P value 0.0005 at 5 d), significantly reduced need for injectable opioids (9.9 ± 3.8 mg versus 4.4 ± 3.4 mg, P value 0.003) and significantly more ventilator-free days (19.9 ± 8.7 d versus 26.4 ± 3.2 d, P value 0.04). There were no statistically significant differences in the total duration of ICU stay (median number of days 2, IQR 1-4.5 versus median number of days 7, IQR 1-14, P value 0.958), need for tracheostomy (36.4% versus 0%, P value 0.155), and pulmonary and pleural complications. ConclusionsSSRF with low-cost materials may provide benefits similar to standard rib plating systems and can be used safely in resource-poor settings.

Evaluation of the Effect of Morphological Structure on Dilatational Tracheostomy Interference Location and Complications with Ultrasonography and Fiberoptic Bronchoscopy.

Background: Percutaneous dilatational tracheostomy (PDT) is the most commonly performed minimally invasive intensive care unit procedure worldwide. Methods: This study evaluated the percentage of consistency between the entry site observed with fiberoptic bronchoscopy (FOB) and the prediction for the PDT level based on pre-procedural ultrasonography (USG) in PDT procedures performed using the forceps dilatation method. The effect of morphological features on intervention sites was also investigated. Complications that occurred during and after the procedure, as well as the duration, site, and quantity of the procedures, were recorded. Results: Data obtained from a total of 91 patients were analyzed. In 57 patients (62.6%), the USG-estimated tracheal puncture level was consistent with the intercartilaginous space observed by FOB, while in 34 patients (37.4%), there was a discrepancy between these two methods. According to Bland Altman, the agreement between the tracheal spaces determined by USG and FOB was close. Regression formulas for PDT procedures defining the intercartilaginous puncture level based on morphologic measurements of the patients were created. The most common complication related to PDT was cartilage fracture (17.6%), which was proven to be predicted with maximum relevance by punctured tracheal level, neck extension limitation, and procedure duration. Conclusions: In PDT procedures using the forceps dilatation method, the prediction of the PDT intervention level based on pre-procedural USG was considerably in accordance with the entry site observed by FOB. The intercartilaginous puncture level could be estimated based on morphological measurements.

Tracheostomy in Patients with Acute Myocardial Infarction and Respiratory Failure.

Patients with acute myocardial infarction (AMI) complicated by respiratory failure require antiplatelet regimens which often cannot be stopped and may increase bleeding from tracheostomy. However, there is limited available data on both the proportion of patients undergoing tracheostomy and the impact on antiplatelet regimens on outcomes. Utilizing the Vizient® Clinical Data Base, we identified patients ≥18 years admitted from 2015 to 2019 with a primary diagnosis of AMI and requiring invasive mechanical ventilation (IMV). We assessed for the incidence of patients undergoing tracheostomy, outcomes stratified by the timing of tracheostomy (≤10 vs >10 days), and the association between dual antiplatelet therapy (DAPT) use and in-hospital mortality. We identified 26 435 patients presenting with AMI requiring IMV. The mean (SD) age was 66.8 (12.3) years and 33.4% were women. The incidence of tracheostomy was 6.0% (n = 1573), and the median IMV time to tracheostomy was 12 days, 55.6% of which underwent percutaneous and 44.4% underwent open tracheostomy. Over 90% (n = 1424) underwent tracheostomy (>10 days) and had a similar mortality when compared to early (≤10 days) tracheostomy (22.5% vs 22.8%, P = 0.94). On the day of tracheostomy, only 24.7% were given DAPT, which was associated with a lower mortality than those not on DAPT (17.4% vs 23.7%, P = 0.01). After multivariable adjustment, DAPT use on the day of tracheostomy remained associated with lower in-hospital mortality (odds ratio 0.68; 95% confidence interval: 0.49-0.94, P = 0.02). Tracheostomy complications were not different between groups (P > 0.05), but more patients in the DAPT group required post-tracheostomy blood transfusions (5.6% vs 2.7%, P = 0.01). Approximately 1 in 20 intubated AMI patients requires tracheostomy. The lack of DAPT interruption on the day of tracheostomy but not the timing of tracheostomy was associated with a lower in-hospital mortality. Our results suggest that DAPT should not be a barrier to tracheostomy for patients with AMI.

Review of surgical treatment of suprastomal collapse in tracheostomised children

Suprastomal collapse (SSC) is considered amajor late complication of paediatric tracheostomy and can be responsible for decannulation failure in up to 20% of tracheostomised children. Depending on the severity of SSC, surgery may be required. Various strategies and techniques are available, of which the treating with airway team should be aware. This article intends to summarise the aetiology of SSC, its classification, clinical presentation, and the gold standard diagnostic and therapeutic algorithms according to the current literature. Apanel of experts reviewed the available literature on SSC. Published evidence on the different surgical techniques and their advantages and disadvantages was reviewed in detail, and atreatment algorithm created. The gold standard diagnostic procedure for SSC is flexible transnasal laryngotracheoscopy in spontaneous breathing followed by microlaryngoscopy (MLS) under general anaesthesia. Two main types of SSC can be differentiated, which differ in terms of surgical treatment. Purely anterior SSC is usually treated by tracheoplasty using an anterior costal cartilage graft (ACCG). Simple closure of the tracheostomy or excision of SSC with apotassium-titanyl-phosphate (KTP) laser are also described as less invasive approaches. For anterolateral SSC, segmental tracheal resection with end-to-end anastomosis or tracheoplasty with ACCG represent promising treatment options. Tracheal reinforcement with absorbable microplates is also discussed in the literature. With both types of SSC and depending on severity and the age of the child, awatch-and-wait strategy should always be considered. Dynamic airway endoscopy in spontaneous breathing followed by MLS in general anaesthesia should always be performed before decannulation. It is particularly important to visualise all segments of the airway during spontaneous breathing. The decision regarding the best surgical option for each child is based on the type and localisation of SSC, as well as on the patient's medical and surgical history and age.

Tracheal Stenosis in Open Versus Percutaneous Tracheostomy.

This study aims to investigate if there is an increased risk of developing tracheal stenosis after tracheostomy with an open versus percutaneous tracheostomy. The patient cohort included patients receiving open or percutaneous tracheostomies at Catholic Health Initiatives Midwest facilities from January 2017 to June 2023. The primary aim was to compare the differences in the risk of developing tracheal stenosis between open and percutaneous tracheostomy techniques. Between-technique differences in the risk of developing tracheal stenosis were assessed via a Cox proportional hazard model. To account for death precluding patients from developing tracheal stenosis, death was considered a competing risk. A total of 828 patients met inclusion criteria (61.7% open, 38.3% percutaneous); 2.5% (N = 21) developed tracheal stenosis. The median number of days to develop tracheal stenosis was 84 (interquartile range: 60 to 243, range: 6 to 739). Tracheal stenosis was more frequent in patients who received a percutaneous tracheostomy (percutaneous: 3.5% vs. open: 2.0%); however, the risk of developing tracheal stenosis was statistically similar between open and percutaneous techniques (HR: 2.05, 95% CI: 0.86-4.94, p = 0.108). This study demonstrates no significant difference in the development of tracheal stenosis when performing an open versus a percutaneous tracheostomy. Tracheal stenosis is a long-term complication of tracheostomy and should not influence the decision about the surgical technique used.

Outcomes of percutaneous versus surgical tracheostomy in an Australian Quaternary Intensive Care Unit: An entropy-balanced retrospective study.

Studies comparing percutaneous tracheostomy (PT) and surgical tracheostomy (ST) complications in the critically ill patient population with high acuity, complexity, and severity of illness are sparse. This study evaluated the outcomes of elective PT versus ST in such patients managed at a quaternary referral center. The primary aim was to detect a difference in hospital mortality between the two techniques. The secondary aims were to compare Intensive Care Unit (ICU) mortality, complications (including stoma site, tracheostomy-related, and decannulation complications), ICU and hospital length of stay, and time to decannulation. This was a single-center retrospective observational study of ICU admission from August 2018 to August 2021. Patients were included if an elective tracheostomy was performed during their ICU admission. Patients with a pre-existing tracheostomy and those who underwent an obligatory tracheostomy requirement (e.g. total laryngectomy) were excluded. Cohorts were matched using Hainmueller's entropy balancing. Binary data were evaluated using logistic regression and continuous data with ordinary least squares regression. 349 patients with a tracheostomy were managed in the ICU during the observation period. They were predominantly males (75% in PT; 67% in ST), with a mean age in the PT and ST group of (47; SD = 18) and (55; SD = 16), respectively. After exclusion, 135 patients remained, with 63 in the PT group and 72 in the ST group. Patients receiving ST were significantly older with a higher Body Mass Index (BMI) than the PT group. There were no significant differences in gender, Acute Physiological And Chronic Health Evaluation (APACHE) III, and the Australian and New Zealand Risk Of Death (ANZROD) between the two groups. There was no difference in hospital mortality between groups (OR 0.91, CI 0.26-3.18, p = 0.88). There were also no differences in ICU mortality, ICU and hospital length of stay, and time to decannulation. PT was associated with a greater likelihood of complications (OR 4.19; 95% CI 1.73-10.13; p < 0.01). PT was associated with a greater risk of complications in those who had this performed early (<10 days of intubation) as well as late (>10 days of intubation). Percutaneous tracheostomy was associated with higher complications compared to surgical tracheostomy. They were related to tracheostomy cuff deflation, stomal site bleeding and infection, sputum plugging, and accidental and failed decannulation. These findings have identified opportunities to improve patient outcomes.

Association Between Modified Frailty Index and Postoperative Outcomes of Tracheostomies.

The 5-item modified frailty index (mFI-5) has been used to stratify patients based on the risk of postoperative complications in several surgical procedures but has not yet been done in tracheostomies. This study investigates the association between the mFI-5 score and tracheostomy complications. Retrospective database review. United States hospitals. The National Surgical Quality Improvement Program database was queried for tracheostomy patients between 2005 and 2018. The mFI-5 was calculated for each patient by assigning 1 point for each of the following comorbidities: diabetes mellitus, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functionally dependent health status. Univariate and multivariable analyses were conducted to determine associations between the mFI-5 score and postoperative complications. A total of 4438 patients undergoing tracheostomies were queried and stratified into the following groups: mFI = 0 (N = 1741 [39.2%], mFI = 1 (N = 1720 [38.8%]), mFI = 2 (N = 726 [16.4%]), and mFI of 3 or higher (N = 251 [5.7%]). Univariate analysis showed that patients with higher mFI-5 scores had a greater proportion of smoking, dyspnea, obesity, steroid use, emergency cases, complications, reoperations, and mortality (P < .001). Multivariable analyses found associations between mFI-5 score and any complication (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.03-2.16, P = .035), mortality (OR: 2.32, 95% CI: 1.15-4.68, P = .019), and any medical complication (OR: 2.75, 95% CI: 1.88-4.02, P < .001). This study suggests an association between the mFI-5 score and postoperative complications in tracheostomies. mFI-5 score can be used to stratify tracheostomy patients by operative risk.

A Systematic Review of Mortality Associations in Patients who Develop Tracheoinnominate Artery Fistula Following Tracheostomy.

Tracheoinnominate artery fistulas (TIFs) are a rare but deadly complication of tracheostomy. Tracheoinnominate artery fistula cases in the literature were summarized in order to understand mortality associations. MEDLINE was searched for studies reporting individual characteristics of patients with TIFs after tracheostomy, excluding cases without tracheostomy or with additional procedures at the tracheostomy site. This study followed PRISMA guidelines. 121 TIF patients from 18 case series and 46 case reports were included. The median age was 40years, and 52.9% were male. The overall mortality rate was 64.5%. There were differences in mortality between cases that presented initially with vs without sentinel bleeding (odds ratio [OR] .34; CI [confidence interval] .16-.73; P = .006). The mortality rate also differed in whether or not the tracheostomy cuff was over-inflated for temporary hemostasis during resuscitation (OR 3.57 (CI 1.57-8.09); P = .002). Treatment compared to no treatment had lower mortality rates (OR .11 (CI 0.04-.32); P < .001); no differences were found if treatment was endovascular vs open surgical. Mortality is a major concern after detection of a TIF and resuscitation paired with endovascular or open surgical intervention is imperative. Rapidly investigating sentinel bleeds and intervening upon hemorrhage with temporary cuff over inflation may lead to improved outcomes.

Surgical and Percutaneous Dilatational Tracheostomy - Technique and Pitfalls

A tracheostomy is usually necessary for long-term mechanical ventilation or complicated weaning. Other indications include swallowing disorders with recurrent aspiration in neuromuscular disease and high-grade subglottic stenosis. The tracheostomy can be performed as a percutaneous dilatational tracheostomy or as a surgical tracheostomy. The complication rate is low, and intraoperative complications are differentiated from early and late postoperative complications. This article aims to present the indications, the techniques and complications of percutaneous dilatational and surgical tracheostomy, and highlights the long-term complications of tracheal stenosis and tracheomalacia.

Microbiological Findings, Infection Risk Factors and Complications Among Children after Tracheostomy

Introduction. Bacterial infection of the respiratory tract is highly common among pediatric patients with tracheostomy, yet there is no wide knowledge about the prevalence of different airway microbes, the incidence of bacterial infection, infection risk factors, and complications. The aim of the study was to analyze the prevalence of airway microbes, the incidence of bacterial infection, infection risk factors, and complications. Methods. Retrospective data of officially reported cases were collected from 2018 to 2022 at Riga Children's Clinical University Hospital (RCCUH). Demographic factors, airway microbiological findings, tracheostomy-related complications, underlying conditions, and outcomes for 37 patients were gathered from the hospital's database Andromeda. The data were analyzed using MS Excel. This study received ethical approval from RSU Ethics Committee. Results. Microbiological analyses were done in 78.3% (n=29) of the cases. Most cultures were obtained from airway aspirate. Altogether 46 different species of microbes were identified. The most frequently identified bacteria were Pseudomonas aeruginosa (in 72.4% of the cases; n=21) and Staphylococcus aureus (65.5%; n=19). Forty-eight percent (n=18) of the patients had respiratory tract infections that required hospitalization. Overall, there were 60 hospitalization episodes of which 51.6% (n=31) were caused by pulmonary bacterial infection, 25.0% (n=15) by non-bacterial infection, and 0.05% (n=3) because of local wound infection. The rest 18.3% (n=11) of hospitalization episodes were due to granulation tissue. The risk factor that showed the greatest significance in the development of bacterial infection was ventilator dependency. Formation of granulation tissue in the airways was found to be the most common complication among pediatric patients with tracheostomy. Conclusion. This study summarizes the most common pathogens, risk factors, and complications, which should be considered while treating pediatric patients after tracheostomy. The results of this study demonstrate that P. aeruginosa and S. aureus have the highest prevalence among these patients. This research is currently used to develop guidelines for pediatric patients with tracheostomy care in RCCUH. Keywords: pediatric tracheostomy; respiratory infections; tracheostomy complications.

Prevention of cuff injury of the intubation tube by blunt window opening in tracheostomy.

One of the intraoperative complications of tracheostomy under general anesthesia is cuff injury of the intubation tube. In the present study, we investigated whether a blunt tracheal opening is a useful method to avoid cuff injury. A retrospective cohort study was conducted to examine patients who underwent tracheostomy under general anesthesia at a single institution from January 1, 2017 to July 31, 2021. Electrocautery was used to thin the connective tissue between the tracheal rings, and bluntly open the trachea with mosquito forceps or similar instruments. Primary outcomes included cuff injury rate, number of surgeons involved, and career as otolaryngologist at the time of surgery. The secondary outcome was perioperative complications. Of the 64 cases, 3 had cuff injuries. 2 of the 3 had cuff injuries during the creation of an anteriorly based flap. 16 surgeons were involved ranging from the first to sixth year as an otolaryngologist, with the third year of otolaryngologist being the most common. The median physician year for instructors was 18 years. The most common postoperative complication was granulation in 9 cases. There were no cases of incorrect cannula insertion or difficulty in cannula insertion. A blunt tracheal opening was considered useful as a method to prevent cuff injury.

Impact of radiological surveillance for major blood vessels on complications of percutaneous dilatational tracheostomy: A retrospective cohort study

PurposePercutaneous dilatational tracheostomy (PDT) is the preferred method for managing long-term ventilator-dependent patients in ICUs. This study aimed to evaluate the association between preprocedural screening (ultrasound Doppler [USD] or computed tomography [CT]) for major neck blood vessels and complications in ICU patients undergoing PDT. Materials and methodsThis was a retrospective cohort study of patients who underwent PDT between 2012 and 2023 at a tertiary referral center. We performed a multivariable analysis and created a propensity-matched cohort. The primary outcome was bleeding within the first seven days after PDT. Secondary outcomes included early and late PDT complications and PTD-related mortality. ResultsA total of 1766 consecutive critically ill patients hospitalized at a tertiary academic hospital were evaluated for PDT. Of these, 881 (49.9 %) underwent only physical examination before PDT, while 885 (50.1 %) underwent additional imaging (CT/USD). A higher proportion of patients in the imaging group were referred to open surgery due to suspected major blood vessels interfering with the procedure (6.2 % vs. 3.0 %, p = 0.001). Among the 1685 patients who underwent PDT, there was no significant difference in the rate of early bleeding between the physical examination group and the imaging group (4.6 % vs. 6.3 %, p = 0.12). Similarly, the overall early complication rates (5.5 % vs. 7.6 %, p = 0.08), late complication rates (1.6 % vs. 2.2 %, p = 0.42), and PDT-related mortality rates (0.7 % vs. 0.6 %, p = 0.73) did not exhibit significant differences between the two groups. In a propensity score-matched cohort, results remained consistent. ConclusionsPhysical examination can effectively identify major neck blood vessels without increasing the risk of bleeding during and after PDT.

A Surgical Audit of Tracheostomy.

To study the magnitude of tracheostomy, its various indications and complications. Prospective Observational Study. A Prospective Observational study was carried out on 640 patients with various indications of tracheostomy admitted in ENT or referred from other departments for tracheostomy from July 2015 to March 2022. The epidemiological data regarding their age, sex, symptoms, indication and complications of tracheostomy were recorded. Necessary interventions were done as and when required. Patients ranged from 6months to 86 yrs. Assisted ventilation was the most common indications for tracheostomy (68.125%, n = 436). The most common complication was subcutaneous emphysema (10.625%, n = 68) followed by tube displacement (5.625%, n = 36. The complication rate was 21.25% and the mortality rate 4.375% (n = 28) with specific mortality rate 0.625% (n = 4). Tracheostomy is one of the commonest surgeries. Data was collected from this study on the various indications of tracheostomy, the epidemiological factors and various complications associated with tracheostomy. Such a data is useful to learn from the mistakes and carry forward the virtouosity.

Biomechanical Evaluation of Tracheal Needle Puncture Forces: Comparative Analysis of Annular Ligaments and Tracheal Cartilage.

Percutaneous tracheotomies (PCT) are commonly performed minimally invasive procedures involving the creation of an airway opening through an incision or puncture of the tracheal wall. While the medical intervention is crucial for critical care and the management of acute respiratory failure, tracheostomy complications can lead to severe clinical symptoms due to the alterations of the airways biomechanical properties/structures. The causes and mechanisms underlaying the development of these post-tracheotomy complications remain largely unknown. In this study, we aimed to investigate the needle puncture process and its biomechanical characteristics by using a well establish porcine ex vivo trachea to simulate the forces involved in accessing airways during PCT at varying angular approaches. Given that many procedures involve inserting a needle into the trachea without direct visualization of the tracheal wall, concerns have been raised over the needle punctures through the cartilaginous rings as compared to the space between them may result in fractured cartilage and post-tracheostomy airway complications. We report a difference in puncture force between piercing the cartilage and the annular ligaments and observe that the angle of puncture does not significantly alter the puncture forces. The data collected in this study can guide the design of relevant biomechanical feedback system during airway access procedures and ultimately help refine and optimize PCT.
