Tracheobronchial tooth and dental prosthesis aspirations: 15 cases.

BACKGROUND: Tracheobronchial foreign body is uncommon in adults. Among foreign body aspirations, tooth and dental prosthesis aspiration is a very rare condition. In the literature, dental aspiration is generally found as a case report and there is no single-center case series. In this study, we aimed to present our clinical experience in 15 cases with tooth and dental prosthesis aspiration. METHODS: Data from 693 patients who presented to our hospital for foreign body aspiration between the years 2006 and 2022 were analyzed retrospectively. Fifteen cases who aspirated tooth and dental prostheses as foreign bodies were included in our study. RESULTS: Foreign bodies were removed by rigid bronchoscopy in 12 (80%) cases and fiberoptic bronchoscopy in 2 (13.3%) cases. In one of our cases, foreign body was expected with cough.When evaluated in terms of foreign body, partial upper anterior tooth prosthesis in 5 (33.3%) cases, partial anterior lower tooth prosthesis in 2 (13.3%) cases, dental implant screw in 2 (13.3%) cases, lower molar crown in 1 (6.6%) case, lower jaw bridge prosthesis in 1(6.6%) case, upper jaw bridge prosthesis in 1(6.6%) case, broken tooth fragment in 1(6.6%) case, upper molar tooth crown coating in 1(6.6%) case and upper lateral incisor tooth in 1(6.6%) case were observed. CONCLUSION: Dental aspirations can also occur in healthy adults. Anamnesis is the most important factor in diagnosis and diagnostic bronchoscopic procedures should be performed in cases where adequate anamnesis cannot be obtained.

Comparison of haemodynamic response to tracheal intubation with two different videolaryngoscopes: A randomized clinical trial

Abstract Background: Endotracheal intubation (ETI), which is the gold standard in coronary artery bypass grafting (CABG), may cause myocardial ischaemia by disturbing the balance between haemodynamic changes and oxygen supply and consumption of the myocardium as a result of sympathetic stimulation. In this study, we aimed to compare two different videolaryngoscopes (C-MAC and Airtraq) in the hemodynamic response to ETI. Methods: Fifty ASA II-III CABG surgery patients were randomly assigned to C-MAC or Airtraq. The hemodynamic data included arterial blood pressure [systolic (SAP), diastolic (DAP) and mean (MAP)] and heart rate (HR) and were recorded at six different points in time: before laryngoscopy-T1, during laryngoscopy-T2, immediately after intubation-T3, and 3 (T4), 5 (T5) and 10 (T6) minutes after intubation. Intraoperative complications were recorded. Patients were questioned about postoperative complications 2 and 24hours following extubation. Results: The hemodynamic response to ETI was significantly greater with C-MAC. The increase in HR started with the laryngoscopy procedure, whereas increases in SAP, DAP, and MAP started immediately after ETI (p = 0.024; p = 0.012; p = 0.030; p = 0.009, respectively). In group analyses, T1-T2, T2-T3 and T1-T3 comparisons did not show any significant differences in HR with Airtraq. However, with C-MAC, HR after intubation increased significantly compared to the pre-laryngoscopy values (T1-T3) (p = 0.004). The duration of laryngoscopy was significantly reduced with C-MAC (p < 0.001), but the duration of intubation and total intubation were similar (p = 0.36; p = 0.79). Conclusions: Compared to C-MAC, the hemodynamic response to ETI was less with Airtraq. Thus, Airtraq may be preferred in CABG patients for ETI.

A Pseudocoarctation of the Aorta With a Left Subclavian Artery Aneurysm, A Case Report and A Review of the Literature.

Here we present a 47-year-old male diagnosed with a pseudocoarctation of the aorta and a funnel-like subclavian artery aneurysm with a large orifice and severe aortic valve insufficiency. The patient underwent a two-stage repair for both pathologies. After an aortic valve replacement, postcardiotomy pericardial effusion occurred and was medically managed. Six months later, the patient underwent a distal arcus aorta and subclavian artery replacement with a left posterolateral thoracotomy as the second stage. Due to the strict adhesions, pulmonary veins were not cannulated and an extracorporeal bypass between the pulmonary artery and femoral artery was used for distal body perfusion. The coincidence of subclavian aneurysms and a pseudocoarctation of the aorta is rare and a literature review was performed to identify treatment options for this pathology.

Coarctation of the aorta with aortic and subclavian artery aneurysms.

Coarctation of the aorta discovered in adulthood is uncommon. The formation of aneurysms from the coarctation segment and in the low-pressure area is even rarer. The surgical management of coarctations can be challenging due to calcifications and concomitant cardiovascular and lung disease. We present a case with coronary artery disease, bilateral bullae, left subclavian artery aneurysm, saccular aortic aneurysms originating proximal to the coarctation and from the coarctation itself, and a remnant of ductus arteriosus. The surgical management and possible histopathologic causes for aneurysm formation are discussed.

Modified Closed Chest Drainage System for Safe Anaesthesia in Patients with COVID-19 Suspicion.

An emergency operation was planned for a patient who developed pneumothorax, subcutaneous emphysema and pneumomediastinum, which was thought to develop secondary to acute diverticulitis. Polymerase chain reaction (PCR) test for coronavirus disease 2019 (COVID-19) diagnosis could not be performed before the operation. In COVID-19 infection, it has been reported that pneumonia, pneumomediastinum and subcutaneous emphysema could be seen in thoracic computed tomography (CT) scan in addition to classic ground-glass opacities. In this study, a modified closed chest drainage system (CCDS) is presented to prevent COVID-19 aerosolisation in a patient undergoing intraoperative tube thoracostomy.

On-pump coronary artery bypass with concomitant descending thoracic aorta-bi-iliac bypass: A case report.

The presence of critical coronary artery disease and concomitant critical limb ischemia represents a clinical challenge. Single-stage operations for cardiac and peripheral revascularization can be an option in such cases. The "Süzer technique" provides a more physiological extra-anatomical vascular reconstruction by using the descending thoracic aorta as the inflow source. This is an alternative to the more widely used technique of ascending aorta to bifemoral bypass and concomitant coronary revascularization. We report a case of critical limb ischemia with juxtrarenal aortic occlusion and left main coronary artery stenosis treated with concomitant coronary artery bypass grafting and descending thoracic aorto-bi-iliac bypass using a modification of the Süzer technique.

Comparison of conventional fluid management with PVI-based goal-directed fluid management in elective colorectal surgery.

Intraoperative fluid management is quite important in terms of postoperative organ perfusion and complications. Different fluid management protocols are in use for this purpose. Our primary goal was to compare the effects of conventional fluid management (CFM) with the Pleth Variability Index (PVI) guided goal-directed fluid management (GDFM) protocols on the amount of crystalloids administered, blood lactate, and serum creatinine levels during the intraoperative period. The length of hospital stay was our secondary goal. Seventy ASA I-II elective colorectal surgery patients were randomly assigned to CFM or GDFM for fluid management. The hemodynamic data and the data obtained from ABG were recorded at the end of induction and during the follow-up period at 1 h intervals. In the preoperative period and at 24 h postoperatively, blood samples were taken for the measurement of hemoglobin, Na, K, Cl, serum creatinine, albumin and blood lactate. In the first 24 h after surgery, oliguria and the time of first bowel movement were recorded. Length of hospital stay was also recorded. Intraoperative crystalloid administration and urine output were statistically significantly higher in CFM group (p < 0.001, p: 0.018). The end-surgery fluid balance was significantly lower in Group GDFM. Preoperative and postoperative Na, K, Cl, serum albumin, serum creatinine, lactate and hemoglobin values were similar between the groups. The time to passage of stool was significantly short in Group-GDFM compared to Group-CFM (p = 0.016). The length of hospital stay was found to be similar in both group. PVI-guided GDFM might be an alternative to CFM in ASA I-II patients undergoing elective colorectal surgery. However, further studies need to be carried out to search the efficiency and safety of PVI.
