Tooth accidental displacement in extraction manoeuvres: a series of two cases

Tooth displacement in bordering anatomical areas is a rare and challenging complication that might occur in the attempt at tooth extraction. Displacement may be attributed to multiple factors, including inadequate clinical evaluation before surgery, an inappropriate extraction plan, the application of excessive force, the use of an incorrect surgical technique, or a lack of experience on the part of the operator. Additionally, anatomical characteristics of the patient must be considered. In this report, we present two examples of tooth displacement and describe the surgical approach adopted to achieve tooth removal.

The Importance of Bone Quality Diagnostics in Preventing Displacement of Dental Implants within the Mandibular Body: A Case Report

Abstract Among the immediate complications that can occur after dental implant placement, accidental displacement within the medullary spaces of the mandibular body is a rare clinical situation. This case report describes implant displacements in the posterior mandibular region and emphasizes the importance of assessing bone density and mandibular medullary patterns prior to implant placement according to a new classification by Lekholm and Zarb modified by Rosas et al. The case reports reported three implant displacements in type II bone of the mandibular body, as classified by Lekholm and Zarb. Following the complication, the bone was reclassified as II-B according to the modification by Rosas et al. The implants were extracted from three female patients aged from 37 to 75 years, with only one having a medical history. All complications were treated and resolved without any alteration after implant removal. To reduce the risk of intraoperative complications that affect the primary stability of dental implants, such as implant migration in the mandibular body, it is important to consider factors that may affect the mechanical locking of the implant at the time of placement, such as the pattern and thickness of the bony trabeculae and the size of the medullary spaces in areas of anatomical risk. For this purpose, we recommend using the modified Lekholm and Zarb classification by Rosas et al. This classification considers the trabecular bone biotype, which helps in planning the surgical approach procedure and establishing a regenerative protocol to minimize the risk of complications with the inferior dental nerve.

Importance of local and systemic factors in preventing implant displacement in the mandibular body: a scoping review of existing literature

BackgroundThe aim of this research was to analyse the current literature on displaced dental implants in the mandibular body, including local and systemic variables related to their cause, and to identify the most frequent location.MethodsThe study conducted a search of three databases (Pubmed, Scopus, and Web of Science) using specific index terms such as ‘dental implant’, ‘displacement’, ‘dislocation’, ‘displaced’, and ‘mandible’. The analysis focused on the direction of displacement and the characteristics of the bone tissue (bone quality, density, and quantity) in cases where dental implants were displaced.ResultsA total of 371 articles were obtained. Thirteen of these articles were selected and read in full. To define bone quality, the Lekholm and Zarb classification, modified by Rosas et al., was used. The type II-B bone, which is characterized by thick cortical bone surrounding cancellous bone with extremely wide medullary spaces, presented the largest number of complications. Twenty-two cases were found in which the displacement direction was horizontal. Of these, four were displaced vestibularly, fourteen lingually, and four remained in the center. Additionally, 24 cases presented vertical displacement, with 12 displaced towards the inferior border of the mandible, 9 towards the middle or adjacent to the inferior dental nerve canal, and 3 above the inferior dental nerve canal.ConclusionThe accidental displacement of implants within the mandibular body is associated with various risk factors, including the characteristics of the bony trabeculum and the size of the medullary spaces. It is reasonable to suggest that only an adequate pre-surgical diagnostic evaluation, with the help of high-resolution tomographic images that allow a previous evaluation of these structures, will help to have better control over the other factors, thus minimizing the risk of displacement.

Temporary Gasserian ganglion stimulation utilizing SNM electrode in subacute herpetic trigeminal neuralgia.

Gasserian ganglion stimulation (GGS) is a neuromodulation technique that has been extensively applied in treating postherpetic trigeminal neuralgia. However, permanent implantation of GGS was preferred in most treatment approaches. Few studies have investigated temporary GGS for the treatment of acute/subacute herpetic trigeminal neuralgia. Moreover, previous research has reported lead dislocation when utilizing traditional electrodes, which was associated with poor pain relief. In GGS research, preventing the accidental displacement of lead following implantation has consistently been a primary objective. We report a case of a 70-year-old woman with subacute herpetic trigeminal neuralgia who underwent temporary GGS for 14 days utilizing a sacral neuromodulation (SNM) quadripolar-tined lead. Computed tomography-guided percutaneous foramen ovale (FO) puncture and temporary SNM electrode implantation were performed during the surgery. A telephone interview was conducted to record a 12-month follow-up. At admission, zoster-related trigeminal pain severity was assessed to be 9/10 on the visual analog scale (VAS). After a 14-day GGS treatment, the pain assessed on the VAS score reduced to 1/10 at discharge but increased to 4/10 at the 12-month follow-up after surgery. Additionally, the anxiety level improved from 58 points to 35 points on the Self-Rating Anxiety Scale (SAS), and the depression level improved from 62 points to 40 points on the Self-Rating Depression Scale (SDS). The Physical Component Summary score of the 12-item Short-Form Health Survey (SF-12) increased from 33.9 to 47.0, and the Mental Component Summary (MCS) score of the SF-12 increased from 27.4 to 41.9. Temporary GGS might be a potentially effective treatment for subacute herpetic trigeminal neuralgia, and an SNM electrode might be a good choice for reducing the risk of dislocation.

In vivo trial of bioresorbable mesh cages contained bone graft granules in rabbit femoral bone defects

Bone graft granules implanted in bone defects come into physical contact with the host bone and form interconnected porous structure. However, there exists an accidental displacement of granules to unintended locations and leakage of granules from bone defects. Although covering the defect with a barrier membrane prevents granule emanation, this procedure is troublesome. To resolve these problems, we fabricated bioresorbable mesh cages (BRMc) in this study. Bone graft granules composed of carbonate apatite alone (Gr) and bioresorbable mesh cages (BRMc/Gr) introduced the bone graft granules and were implanted into the bone defect in the rabbit femur. Micro-computed tomography and histological analysis were conducted at 4 and 12 weeks after implantation. Osteoprogenitors in the bloodstream from the host bone passed through the pores of BRMc, penetrated the porous structure of graft granules, and might interact with individual granules. Then bone remodeling could progress actively and new bone was formed. The new bone formation was similar to the host bone at 12 weeks and there were minimal signs of local tissue inflammation. BRMc/Gr could reduce the risk of unwanted new bone formation occurring due to loss of granules from the bone defects compared with Gr because BRMc enclosed granules and prevent granules leakage from bone defects and BRMc could not induce unfavorable effects to forme new bone. Additionally, BRMc/Gr could keep granules assembled in one place, avoid displacement of granules to unintended locations, and carry easily. These results demonstrated that BRMc/Gr was effective in bone regeneration and improved clinical handling.

Peripheral arterial catheter securement and catheter survival in the pediatric intensive care unit.

Peripheral arterial catheters (PACs), and their associated complications, are common in the pediatric intensive care unit (PICU). Accidental catheter displacement and non-functional PACs are the most common complications, and this may be related to inadequate catheter securement. There is mixed guidance on the best way to secure PACs to prevent complications. The authors hypothesized that sutures would not be associated with a decreased risk of malfunction or accidental removal. This was a single center retrospective cohort study at a quaternary-care PICU. PICU patients with a peripheral arterial catheter placed in the PICU from 7/2020 to 1/2023 were included. The primary outcome was unplanned PAC removal. A univariate and multivariate Cox proportional hazards regression analysis was performed, using patient weight, sedation, paralytic, and role of the proceduralist as covariates. The secondary outcome was survival probability. A log-rank test was used to compare survival curves. Of 761 PACs that met inclusion criteria in 437 unique patients, 599 were sutured (78.7%) and 162 were un-sutured (21.3%). In 257 cases (33.8%), the PAC had an unplanned removal. Among all PACs, the median duration of PAC placement was 5.3 days (IQR 2.1-10.5 days). There was an unplanned removal rate of 42.2% (68) in the un-sutured group and 31.4% (188) in the sutured group (p < 0.001). In multivariable analysis, sutured PACs were also associated with a lower rate of unplanned removal (hazard ratio, 0.59; 95% CI, 0.44-0.78). Use of continuous sedation was also associated with an increased risk of unplanned removal of PACs (hazard ratio, 1.54; 95% CI, 1.10-2.16). There was a 50% survival probability at 13.3 days for un-sutured PACs and 23.7 days for sutured PACs. Suturing is associated with fewer unplanned removals and longer catheter survival, compared to un-sutured PACs in pediatric patients.

Continuous monitoring of endotracheal tube position with near infrared light.

Endotracheal intubation is a common approach for airway management in critically ill patients. However, the position of the endotracheal tube (ETT) may be altered during the procedure due to head movements. Accidental displacement or dislodge of the ETT may reduce the airflow, leading to moderate to severe complications, and in some cases even fatality. Therefore, timely detection of changes in ETT position in the trachea is critical to ensure immediate and intermediate interventions to maintain the ETT in the proper position. Currently, there are no widely utilized tools for real-time monitoring of ETT positions. The goal of this study is to develop a cost-effective and easy-to-use near-infrared (NIR) device, named Opt-ETT, capable of continuously monitoring the ETT position in the trachea of a patient. A side-firing fiber is attached to the side of the ETT to illuminate the trachea tissue with NIR light, and a detector board containing five phototransistors is affixed to the chest skin to measure the intensity of diffusely transmitted light. Displacement of the ETT is estimated using second-order polynomial fitting to the ratios of the phototransistor readings. Monte Carlo simulations, ex vivo experiment on porcine tissue, and in vivo experiments using a swine model have been conducted to assess the feasibility of the device. The design of the Opt-ETT device has been verified by the Monte Carlo simulations and ex vivo experiment. The estimation of displacement from in vivo experiments using the Opt-ETT exhibited a high degree of agreement with that measured by a reference sensor, with a discrepancy between to within a displacement range from to . The Opt-ETT device provides a potentially cost-effective solution for real-time and continuous monitoring of ETT position in patient during an intubation procedure.

Advanced Orotracheal Tube Fixation Techniques in Severe Burn Patients: Innovations from a Chilean Hospital

Since its foundation, the Hospital Emergency Public Assistance in Santiago, Chile, has been the national reference center for managing severe burn patients. In 2007, more than 6,000 hospital admissions for burns were registered in Chile due to the severity of the clinical condition. These patients must be treated in intensive care units. Therefore, the use of orotracheal tubes is essential for its management. The correct stabilization of these devices avoids complications or airway risks. In the Major Burn Unit, cotton cloth restraints and transpore-type adhesives are used on the user's face, but in patients with facial territory compromise, these cause tissue damage; due to this, the Dental Unit has innovative techniques of orotracheal tube fixation, using stainless steel and plastic wire ties, which have allowed to reduce the risks of extubation and accidental displacement of the tube, improving its stability. This work describes the technique used in orotracheal tube fixation in two patients with severe burns, performed by the Dental Unit of the Hospital Emergency Public Assistance, Dr. Alejandro del Río, Chile.

Deformation analysis of buried subsea pipeline under different pressure-reverse​ fault displacement loading paths

The combined action of subsea seismic faults and pressure loads can cause pipelines to reach the limit state. Consequently, various failure modes, such as global buckling and system collapse, can occur. In this study, the deformation of a buried subsea pipeline under different pressure-reverse fault displacement loading paths is investigated using the nonlinear vector form intrinsic finite element (VFIFE). To quantify the damage to the pipeline and identify its failure modes under accidental reverse fault displacement, the loading path ‘fault displacement → internal/external pressure’ was analysed first. The post-earthquake resumption and reconditioning of unpressurised and pressurised pipelines, respectively, are evaluated based on the performance criteria in terms of strain and deformation. The corresponding loading paths are simplified as ‘ambient hydrostatic pressure → fault displacement → operation pressure’ and ‘operation pressure → fault displacement → external over pressure’. Moreover, the residual bearing capacity, weak position, and possible failure behaviour of the pipeline are comprehensively analysed for all subsequent external overpressures. The results show that the loading paths have a significant effect on structural responses, particularly on the elasto-plastic deformation. The two yield bends of a deformed pipeline under fault displacement are dangerous regions. Their inadequate relative residual strength leads to several successive local collapses and determines the occurrence and direction of buckling propagation during the subsequent external overpressure. The previous internal pressure has a significant influence on the residual capacity and failure modes of the pipeline, particularly the strain hardening effects with the influence of large seismic faults. The critical points of the first local collapse have specific characteristics, and the minimum residual resistance to external over pressure occurs when the maximum flattening parameter is 15% under initial fault displacement. The results of this study can guide the development of seismic design methodologies and engineering practice for buried subsea pipelines.

RETRIEVAL OF DISPLACED ROOT FRAGMENT ASSOCIATED WITH FUNGAL BALL IN THE MAXILLARY SINUS USING FUNCTIONAL ENDOSCOPIC SINUS SURGERY- A CASE REPORT

Introduction: Fungal ball is a non-invasive sinus disease and the incidence of this disease has increased in recent years and also several case reports and case series have suggested a relationship with the accidental displacement of root into maxillary sinus. We report a case where fungal ball was removed along with the dental root fragment which was accidentally displaced into the maxillary sinus following traumatic dental extraction. A 32-years-o Case Report: ld female patient presented to Maxillofacial Surgery Department with complaint of pain in the left orofacial region for one month. The patient had a history of traumatic extraction of posterior maxillary teeth 4 years back. On examination, no dental cause of pain was detected. On further evaluation, a foreign body within the left maxillary sinus was seen in the panoramic radiograph. Computed tomography images revealed displaced root in the left maxillary sinus with surrounding heterogenous soft tissue opacity. Following the detection of foreign body, patient underwent Functional Endoscopic Sinus Surgery (FESS) and the root was retrieved and the adjacent soft tissue specimen was sent for histopathological examination. The presence of fungus consistent with the Aspergillus species was confirmed. Conclusion: This article emphasizes the importance of atraumatic dental extraction, the association of fungal ball with displaced root and the utility of FESS in clearing the same.

Pandemic as Portal: Disrupting the Violence of Epistemicide in Teacher Education

Epistemicide involves more than just the accidental displacement of different knowledges. By its very nature, epistemicide involves the intentional silencing, devaluing, and violent destruction of knowledge systems (Mignolo, 2007). While much has been written about radically altering education by including other knowledge in schools, what this entails within the context of teacher education methods courses, particularly during the pandemic, has received less attention. This paper examines and discusses what creating another teacher education might involve by probing some of the spaces and openings for epistemic disobedience exposed and made visible during the pandemic. My conceptualization of another teacher education simultaneously theorizes what might be possible in terms of epistemic pluralism while also confronting the erasure and displacement of different knowledge systems in teacher education courses.

Ultrasound-guided posterior tibial artery cannulation as a rescue for intraoperative accidental arterial line displacement in the prone position: A case report

Arterial cannulation for patients in prone position poses a great challenge for the anaesthesiologists because of restricted anatomical access and technical difficulty in needle advancement. In such a problematic scenario, ultrasound might be hugely helpful. We report a case of a 42-year-old male who underwent Atlanto-occipital fusion in prone position. Intraoperatively the left radial arterial cannula got dislodged accidentally. The right posterior tibial artery was cannulated under ultrasound guidance by long-axis in-plane approach as a rescue technique for continued management without disturbing the procedure and inconvenience to the team. The procedure was successful on the first attempt.

Iatrogenically Displaced Lower Wisdom Tooth Into Submandibular Space: A Case Report And Review On Retrieval Approaches

Accidental displacement of wisdom tooth and its elements are one of the uncommon complications. The common facial spaces involved during the displacement of lower wisdom teeth are Sub mandibular, Sublingual and Pterygomandibular spaces. Such complications have adverse physical and psychological impact over the patients. The management can vary from conservative observation to surgical retrieval; depending on the presenting clinical conditions, location and the relationship of the displaced elements with respect to the anatomic structures. Retrieval of a displaced root tip from these spaces may be complex due to poor visualization, limited access and under limited experience. This is a case report with a review on approaches for surgical retrieval, of a young male patient aged 28 years, who presented with a displaced mandibular third molar root into the Submandibular space during unsuccessful surgical removal by a general practitioner 2 weeks earlier. The presenting complaints were Limited mouth opening and pain during chewing on the right lower jaw. The case was managed surgically through extra oral approach under local anesthesia and MAC.

Maxillary Third Molar Tooth Accidentally Displaced in Buccal Space: Report of Two Cases.

The extraction of retained and completely impacted third molars is one of the most common surgical procedures performed by dental practitioners with low rates of complications. The accidental displacement during the surgeries of the maxillary third molar into adjacent anatomical spaces is one of the most critical problems that can arise. The most common sites of migration during surgical interventions are the infratemporal fossa, the pterygomandibular space, the maxillary sinus, the buccal space, and the lateral pharyngeal space. In this paper, two cases in which a maxillary third molar accidentally was displaced into the buccal space are presented, the retrieval of the tooth via intra-oral approach is explained, and the anatomical spaces implications are discussed.

A CURIOUS CASE OF URINOTHORAX

TOPIC: Disorders of the Pleura TYPE: Medical Student/Resident Case Reports INTRODUCTION: Urinothorax (UT), is a rare cause of pleural effusion caused by accumulation of urine in the pleural space. It is usually the result of trauma or obstruction of the urinary tract. We present a case of a tension UT developed due to accidental displacement of a ureteral stent. CASE PRESENTATION: 80-year-old male with medical history significant for chronic kidney disease stage III, nephrolithiasis, prostate cancer status post prostatectomy and hospitalizations for obstructive uropathy requiring ureteral stent placement presented with progressively worsening dyspnea and acute encephalopathy. He was hypotensive and hypoxic requiring admission to the intensive care unit. Of note, patient was discharged 2 days ago after exchange of double J ureteral stent and removal of nephrostomy tube. Physical examination revealed a confused elderly male in respiratory distress. Patient had absent breath sounds and dullness on percussion of the right chest. Laboratory investigations were consistent with acute kidney injury. His imaging showed complete opacification of right hemithorax, consistent with large right sided pleural effusion and mediastinal shift to the left. Commuted tomography (CT) of the chest showed proximal aspect of the ureteral stent had migrated into the right pleural space. A chest tube was placed with drainage of yellow colored fluid and resolution of hypotension and hypoxia. On analysis, pleural fluid was transudative in nature with creatinine of 10.5 mg/dl. The findings of pleural fluid analysis including serum creatinine ratio greater than 1 and imaging confirmed the diagnosis of UT. The chest tube was kept in place for the drainage of urinoma and J-stent was removed under general anesthesia with repeat imaging showing resolution of the pleural effusion. DISCUSSION: UT usually presents as unilateral or bilateral pleural effusion usually due to trauma or obstruction of urinary tract. It has a male predominance and can occur at any age. Traumatic etiologies including surgical injuries, blunt trauma, medical procedures etc. are common causes of UT. Less commonly, UT can be due to obstructive causes due to prostate disease, left renal vein obstruction etc. Patients usually present with symptoms of flank pain, shortness of breath, or decreased urine output. Diagnosis is made on pleural fluid analysis with pleural fluid to serum creatinine ratio greater than 1 with associated obstructive or traumatic uropathy. Treatment of UT is by draining the pleural fluid and correcting the underlying etiology. To our knowledge, this is the first case reported of urinothorax secondary to ureteral stent displacement into the pleural space. CONCLUSIONS: UT is a rare but curable cause of pleural effusion. Though there is paucity of data, however, according to the reported causes patients have favorable prognosis if diagnosed early.

Analysis of frequency and risk factors for complications of enteral nutrition in children in Poland after percutaneous endoscopic gastrostomy placement

ObjectivesThe aim of the study was to assess the complication rate and identify whether age, nutritional status, and history of respiratory aspiration prior to percutaneous endoscopic gastrostomy (PEG) are risk factors for post-PEG placement complications in Polish children. In addition, the safety of two enteral feeding methods (3 h vs. 8 h) after PEG insertion in children was compared. MethodsChildren with clinical indications for PEG placement were recruited from six medical centers in Poland to participate in the study. The patients were centrally randomized to receive the first bolus feed via a feeding tube at 3 h (group 1) or 8 h (group 2) after PEG placement. The preprocedural preparation, postoperative care, and resumption of feeding were performed on all of patients in accordance with the study protocol. Patients were followed for 12 mo. ResultsOf the 97 randomized patients, 49 were assigned to group 1 and 48 to group 2. Full feed after PEG placement was achieved within 24 to 48 h in most cases (74% vs. 82%). There were no differences between the groups regarding the number of early mild (31.3% vs. 31.3%) and serious (2.1% vs 8.3%) complications or the duration of hospitalization after PEG placement (P > 0.05). The most common serious complication after PEG placement was accidental displacement of PEG. Most reported late complications were mild. The results of the regression analysis indicate no statistically significant effect of age, body mass index standard deviation score, white blood cell count, serum albumin level, and respiratory aspiration in the medical history on the occurrence of mild and severe complications. ConclusionsThe early initiation of post-PEG feeding was not associated with an increase in the number of complications. Most complications after the PEG procedure were mild. Age, serum albumin level, white blood cells, body mass index standard deviation score, and a history of aspiration to the respiratory tract were not confirmed as a risk factor for post-PEG complications in children.

Accidental intraosseous displacement of mandibular premolar root during extraction with guidance and literature review

ABSTRACTIntroductionIatrogenic displacement of teeth during extraction is a rare complication, commonly associated with third permanent molars and their displacement into fascial spaces. We wish to raise awareness of intraosseous tooth displacement as a potential risk of routine exodontia with possible serious consequences. The prevention and management of displaced teeth are discussed. We present a rare case of apical, intraosseous displacement of a mandibular premolar root during attempted extraction; resulting in paraesthesia.Presentation of CaseA 30‐year‐old woman was referred to the Oral and Maxillofacial department with paraesthesia to the left lower lip, chin and anterior gingivae following a failed extraction of the lower left second premolar tooth (LL5) by her general dental practitioner. Intra‐oral examination showed no visible tooth at the extraction site, but an orthopantogram (OPG) and Computed Tomography (CT) mandible confirmed apical, horizontal and intraosseous displacement of the retained LL5 root which was in close proximity to the inferior dental nerve, and inferior to the LL6. Surgical intervention was required and involved raising a mucoperiosteal flap, buccal bone removal and root retrieval through the bony window. Post‐operatively, the surgical site healed uneventfully, however, there was persistent paraesthesia.ConclusionOn literature search, this is the first reported intraosseous displacement of a mandibular premolar during dental extraction.This case highlights the importance of safe extraction techniques. Care must be taken to ensure controlled force and correct positioning of instruments to minimise such complications.

An unprecedented displacement of root piece in the infratemporal fossa: a case report

ABSTRACTThere are various reports of displaced maxillary third molar in the infratemporal fossa (IFT) in the literature. However there are no reported cases of a displaced root piece in the IFT. Here we have described a case of an accidental displacement of root piece of maxillary third molar into the IFT by a resident due to lack of surgical judgement and how this case was investigated and managed by our surgical team. There is no specific protocol for management of such complication in literature. The aim of this article is to identify the errors which lead to displacement of tooth in IFT and to establish a stepwise protocol to manage the same. We have highlighted a few basic steps for young practitioners to avoid such complications and also to manage them if at all they do occur.

Accidental Displacement of Third Molar Root into the Lingual Pouch

Third molar surgery is the most common procedure performed by oral and maxillofacial surgeons. A thorough understanding of the complications associated with this procedure will enable the practitioner to identify and counsel high-risk patients, appropriately manage more common complications, and be cognizant of less common sequelae and the most effective methods of management. We present a case of displaced third molar root into the lingual pouch (submandibular space) and ways to prevent and manage this rare complication. In this article, we have compared different surgical approaches for the removal of displaced root from the submandibular space.

Feasibility, safety, and resource utilisation of active mobilisation of patients on extracorporeal life support: a prospective observational study

BackgroundThere is scarce evidence on the feasibility, safety and resource utilisation of active mobilisation in critically ill patients on extracorporeal life support (ECLS).MethodsThis prospective observational single-centre study included all consecutive critically ill patients on ECLS admitted to an academic centre in Germany over a time period of one year. The level of mobilisation was categorised according to the ICU Mobility Scale (IMS). Primary outcome was complications during mobilisation.ResultsDuring the study period, active mobilisation with an activity level on the IMS of ≥ 3 was performed at least on one occasion in 43 out of 115 patients (37.4%). A total of 332 mobilisations with IMS ≥ 3 were performed during 1242 ECLS days (26.7%). ECLS configurations applied were va-ECMO (n = 63), vv-ECMO (n = 26), vv-ECCO2R (n = 12), av-ECCO2R (n = 10), and RVAD (n = 4). Femoral cannulation had been in place in 108 patients (93.9%). The median duration of all mobilisation activities with IMS ≥ 3 was 130 min (IQR 44–215). All mobilisations were undertaken by a multi-professional ECLS team with a median number of 3 team members involved (IQR 3–4). Bleeding from cannulation site requiring transfusion and/or surgery occurred in 6.9% of actively mobilised patients and in 15.3% of non-mobilised patients. During one mobilisation episode, accidental femoral cannula displacement occurred with immediate and effective recannulation. Sedation was the major reason for non-mobilisation.ConclusionsActive mobilisation (IMS ≥ 3) of ECLS patients undertaken by an experienced multi-professional team was feasible, and complications were infrequent and managed successfully. Larger prospective multicentre studies are needed to further evaluate early goal directed sedation and mobilisation bundles in patients on ECLS.
