double lumen tube ultrasound

A percutaneous cholecystostomy tube (PCT) is the conventionally favored nonoperative intervention for treating acute cholecystitis. However, PCT is beset by high adverse event rates, need for scheduled reintervention, and inadvertent dislodgement, as well as patient dissatisfaction with a percutaneous drain. Recent advances in endoscopic therapy involve the implementation of endoscopic transpapillary drainage (ETP-GBD) and endoscopic ultrasound-guided gallbladder drainage (EUS-GBD), which are increasingly preferred over PCT due to their favorable technical and clinical success combined with lower complication rates...

Anthropometric measurements like height and gender have been frequently found to be inaccurate in prediction of size of double lumen tube (DLT). A tracheal ultrasonography (TUS) is a technique that can be used to predict the size of DLT and its correct placement for lung isolation. We aim to check the accuracy of ultrasound over clinical methods. This prospective study included 68 patients undergoing elective thoracic surgery requiring one-lung ventilation (OLV) with DLT. The groups were assessed for the size of DLT by either anthropometric measurement using height and gender (Group C) or ultrasound method (Group U)...

BACKGROUND: Postoperative sore throat (POST) is one of the more common side effects of tracheal intubation patients under general anesthesia (GA) after extubation using double-lumen endobronchial tubes (DLTs). The internal branches of the superior laryngeal nerve (SLN) block (iSLNB) have been reported to anesthetize the larynx for airway manipulation (such as awake tracheal intubation) and pain treatment efficiently. We hypothesized that ultrasound-guided iSLNB (US-guided iSLNB) combined with GA would ameliorate the incidence and severity of POST and hoarseness...

We describe a 15-year-old female diagnosed with necrotizing pancreatitis in the setting of coronavirus disease 2019 with severe complications including splenic vein and portal vein thromboses, pleural effusion requiring chest tube, acute hypoxic respiratory failure requiring noninvasive positive-pressure ventilation, and new-onset insulin-dependent diabetes mellitus, requiring over a month-long hospitalization. Following discharge, the patient experienced a prolonged loss of appetite, nausea, and extreme weight loss...

OBJECTIVES: Insertion of a double-lumen endotracheal tube (DLT) is the most commonly used method for one-lung ventilation (OLV). This meta-analysis was aimed at investigating the performance of lung ultrasound in assessing the DLT position in OLV. METHODS: Electronic databases were searched for related trials from inception to October 2022. The primary outcome was the performance of ultrasound or clinical evaluation in confirming the correctness of the DLT position, using fiberoptic bronchoscopy or intraoperative direct visualization of lung collapse as the gold standard...

BACKGROUND: In thoracic surgeries requiring thoracotomy incisions, correct positioning of the double-lumen endotracheal tube (DLT) is mandatory. After the pandemic of novel COVID-19, using simple, noninvasive technology such as lung ultrasound (LUS) can be important in avoiding the possibility of spreading infectious diseases or contagious infections that can follow using fiberoptic bronchoscopy (FOB). OBJECTIVES: We aimed to assess the accuracy of auscultation and LUS in relation to FOB in the assessment of DLT placement and to identify the possibility of using LUS as an alternative to FOB during DLT insertion...

BACKGROUND: Postoperative sore throat (POST) is one of the main adverse postoperative outcome after tracheal intubation using double-lumen endobronchial tubes (DLTs). The aim of this study was to investigate the effectiveness and safety of ultrasound (US)-guided block of the internal branch of the superior laryngeal nerve (iSLN) for alleviating POST after intubation of DLTs. METHODS: Patients undergoing thoracic surgery between August 2019 and August 2021 were randomized into two groups depending on whether they received US-guided iSLN block immediately after the operation...

BACKGROUND: Spray-as-you-go (SAYGo) airway topical anesthesia and nerve block are common techniques used during awake tracheal intubation. However, their effects have not been described during double-lumen tube intubation. We report on a prospective randomized study that aimed to compare the intubation effects of SAYGo and nerve block patients undergoing thoracic surgery. METHODS: Sixty-six American Society of Anesthesiologists (ASA) physical status I and II patients were scheduled to undergo double-lumen tube (DLT) tracheal intubation for thoracic surgery...

BACKGROUND: Appropriate placement of left-sided double-lumen endotracheal tubes (LDLTs) is paramount for optimal visualization of the operative field during thoracic surgeries that require single lung ventilation. Appropriate placement of LDLTs is therefore confirmed with fiberoptic bronchoscopy (FOB) rather than clinical assessment alone. Recent studies have demonstrated lung ultrasound (US) is superior to clinical assessment alone for confirming placement of LDLT, but no large trials have compared US to the gold standard of FOB...

One-lung ventilation provided by double-lumen tube intubation under general anaesthesia has conventionally been considered necessary for thoracoscopic major pulmonary resections. Recently, regional anaesthesia techniques have been used to avoid complications of tracheal intubation and general anaesthesia. Although paravertebral block (PVB) comes to the fore as a safe and useful regional anaesthesia technique for intra-operative and post-operative analgesia for a wide variety of surgeries involving the thoracic and lumbar regions, it is sometimes used for anaesthesia...

Background: Currently, there is no uniform standard for selecting the left double lumen tubes (LDLT). Advantages, such as safety and convenience of the ultrasonic technology, and measurement accuracy, make it more widely applied in the clinical anesthesia, and computed tomography (CT) multi-planar reconstruction (MPR) technology will certainly provide a more accurate measurement. For better application for thoracic surgery choice LDLT, relieving the injury to patients, and reducing the complications, this study will compare the two approaches...

Pancreatic fluid collections are surrounded by a wall of granulation tissue and may contain necrotic debris. They occur following a severe acute pancreatitis and most of the cases resolve spontaneously after several weeks. However, their management may lead to a very hardto-treat condition, requiring a multidisciplinary approach. During the last decades we assisted to a change of paradigm involving Endoscopic Ultrasonography, from a pure diagnostic technique to an interventional-therapeutic one, allowing an effective, safe and less invasive approach than other existing treatment standards, historically consisting of surgical and percutaneous drainage...

In the recent decades, flexible bronchoscopy has replaced lung auscultation to confirm more precisely the placement of a double-lumen endotracheal tube (DLT) for thoracic surgery. However, bronchoscopes are costly and not always available. Lung ultrasound has been described in the literature as an alternative to confirm left DLT placement and lung isolation. In this case report, we describe a pediatric thoracic case in which lung ultrasound was utilized to confirm correct placement of a right-sided DLT.

Lung ultrasound (LUS) is a practical tool for lung diagnosis when computer tomography (CT) is not available. Recent findings suggest that LUS diagnosis is highly advantageous because of its mobility and correlation with radiological findings for viral pneumonia. Simple models for both educational evaluation and technical evaluation are needed. Therefore, this work investigates the usability of a large animal model under aspects of LUS features of viral pneumonia using saline one lung flooding. Six pigs were intubated with a double-lumen tube, and the left lung was instilled with saline...

BACKGROUND AND AIM: Lumen-apposing metal stent is widely used for endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) nowadays but not approved in many countries and might be unsuitable for elective laparoscopic cholecystectomy (LC) because of its large enterocholecysto fistula. A combination of double pigtail plastic stent (DPPS) and naso-cystic tube (NCT) could overcome these problems. The aim of this study was to estimate the efficacy and safety of this method in patients with acute cholecystitis unfit for urgent cholecystectomy both as bridge to surgery and palliation...

BACKGROUND AND AIM: Treatment efficiency of walled-off necrosis (WON) using endoscopic ultrasound-guided drainage (EUS-D) with a double pigtail stent (DPS) is limited. Endoscopic necrosectomy is often carried out if EUS-D fails. However, endoscopic necrosectomy is associated with significant morbidity and mortality. Thus, we developed transmural nasocyst continuous irrigation (TNCCI) as an alternative therapeutic option for WON. This study aimed to evaluate the usefulness of TNCCI therapy for WON...

RATIONALE: Endoscopic ultrasound (EUS)-guided treatment has been recently described for internalizing refractory pancreaticocutaneous fistulas (PCFs). However, the existing techniques are limited because of the difficulty in accessing nondilated pancreatic ducts or fistulas. In an attempt to overcome this limitation, we present a case where a EUS-guided intervention utilizing a balloon-target technique was employed to internalize a PCF into the stomach. PATIENT CONCERNS: A 78-year-old woman underwent percutaneous drainage and 4 percutaneous endoscopic necrosectomies for walled-off pancreatic necrosis (WOPN) after severe acute pancreatitis due to choledocholithiasis...

BACKGROUND: Left double-lumen tubes (LDLTs) are used in thoracic surgery to allow one-lung ventilation. Their size is usually chosen on the basis of clinical parameters (height, sex). Double-lumen endobronchial tubes are frequently undersized/oversized, risking tube displacement or tracheal trauma. A correlation between ultrasound tracheal diameter and left main bronchus dimension has been demonstrated. OBJECTIVES: We hypothesised that the insertion of undersized/oversized double-lumen tubes is frequent when the size is selected using standard criteria, and that the use of ultrasound to estimate tracheal diameter may help to reduce the frequency of insertion of oversized tubes...
