Impact of Initial Surgical Interventions on Empyema Outcomes: Insights From a Cohort Study in Yemen.

Purpose The study aimed to evaluate the effectiveness of different initial interventions, including thoracostomy drain tubes, open thoracotomy with decortication, and video-assisted thoracoscopic surgery (VATS) thoracoscopy in the management of empyema. Methods This prospective cohort study was conducted at two teaching hospitals in Sana'a, Yemen, over a two-year period from 2022 to 2024. The study included 40 patients diagnosed with empyema, categorized according to the type of initial intervention received. Demographic data, clinical presentation, imaging findings, intervention details, and outcomes were systematically collected and analyzed. Statistical analyses were performed to identify associations between demographic characteristics, empyema stage, intervention type, and treatment success. Results The study included 40 patients with a higher proportion of males (67.5%) than females (32.5%). The mean age was 47.1 years (standard deviation (SD): 12.85). The overall success rate of the initial interventions was 55%, with significant variation based on empyema stage, comorbidities, and intervention type. Stage I empyema had the highest success rate (80%), followed by Stage II (50%) and Stage III (27.3%), with a statistically significant difference (p = 0.034). Smoking history was identified as a significant negative predictor of success (p = 0.001). Higher pleural fluid pH was associated with better outcomes (p = 0.015). The most common complications were chest infections (20%) and bronchopleural fistulas (10%), with a mortality rate of 7.5%. Conclusion The empyema stage significantly affects the success rate, with early stages showing better outcomes. Early and appropriate intervention, particularly in later stages, is crucial for better outcomes. Effective management of postoperative complications is vital. This study highlights the need for early diagnosis and tailored interventions based on the empyema stage to improve patient outcomes. Future research should focus on larger multicenter studies to validate these findings and develop standardized treatment protocols.

Evaluation of the Outcome of Interventions for Thoracic Endometriosis Syndrome at a Tertiary Level Health Institution in Southern Nigeria

Background: Thoracic Endometriosis Syndrome (TES) is a clinical condition characterized by the presence of endometrial tissue within the thoracic cavity, catamenial pneumothorax, catamenial haemothorax, catamenial haemopneumothorax, catamenial haemoptysis and or endometrial nodular lung mass. The management can be challenging as treatment is fraught with recurrence.
 Aim: To evaluate the outcome of interventions for Thoracic Endometriosis Syndrome.
 Methods: This was a prospective cross-sectional study of 14 patients with thoracic endometriosis syndrome who were managed at the university of Port Harcourt Teaching Hospital between August 1, 2017, and July 31, 2023. A proforma was used to collect data on socio-demographic characteristics, clinical presentation, type of intervention and evidence of recurrence of chest symptoms and entered into a spread sheet. Data analysis was done with SPSS version 28. Results are presented as frequency tables and percentages.
 Results: The age of the patients ranged between 20 and 44 years. Of the 14 patients, 11 (78.6%) were married, and 3 (21.4%) of the patients had established abdominal endometriosis with symptoms of thoracic endometriosis, while 4 (28.6%) had a histologic diagnosis of thoracic endometriosis. Pneumothorax was observed in 9 (64.23%) patients, 3 (21.43%) had haemopneumothorax, 2 (14.29%) with cyclical haemoptysis and haemothorax, and 4 (28.57%) of the patients had thoracic endometriotic nodules, while all the married patients had primary infertility. Twelve (85.7%) of the patients had closed tube thoracostomy drainage (CTTD) with chemical pleurodesis, while 4 (28.6%) had thoracotomy, decortication, bleb, and nodules resection with chemical pleurodesis. All the patients had hormonal therapy using luteinizing hormone-releasing hormone (LHRH) analogues. There was recurrence in 2 (14.3%) of the patients after a one-to-six-year period of follow-up.
 Conclusion: The treatment of TES using CTTD with pleurodesis, thoracostomy, decortication, bleb resection and or hormonal therapy with appropriate patient selection is effective as only two cases of recurrences were recorded.

Ventricular penetration with a rigid drainage catheter as a procedural complication caused by space‐occupying intrathoracic mass with significant cardiac displacement in a dog

AbstractA 3‐year‐old, female, entire labrador retriever was presented as an emergency referral for suspected iatrogenic cardiac trauma during thoracostomy tube placement for perceived pyothorax. The patient initially presented for non‐specific lethargy and anorexia and upon investigations was found to have a mass on the external thoracic wall and what appeared to be a large‐volume pleural effusion. During thoracostomy drain placement, fresh, clotting blood was aspirated through the drain. The patient was haemodynamically stable on arrival at the referral centre with a normal electrocardiogram. Imaging revealed penetration of the left ventricular free wall and septum and significant displacement of the heart due to a large intrathoracic space‐occupying mass. Cytology of the mass was suggestive of soft tissue sarcoma. The patient was euthanased.

Empyema Thoracis Caused by Klebsiella Spp and Escherichia coli Co-Infection - An Uncommon Isolation with Atypical Presentation

Empyema thoracis is the collection of pus in the pleural space. A 9-year-old boy presented with a 3-day history of high grade continuous fever, a day history of abdominal pain, distension and fast breathing. Examination findings: acutely ill child, febrile, in respiratory distress. Chest findings: tachypnea, dull percussion note and decreased air entry on the right hemithorax. Chest radiograph: massive fluid collection in the right hemithorax. A pleural tap yielded frank pus that was sent for microscopy, culture and sensitivity (MCS). Escherichia coli was cultured which was sensitive to fluoroquinolones. Klebsiella spp was also cultured from the blood sample taken for MCS and yielded the same sensitivity. Patient responded well to tube thoracostomy drainage and administration of antibiotics. Empyema thoracis with the isolation of two-gram negative organisms in a previously healthy child is rare.

Delayed Diagnosis and Treatment of an Occult Hemothorax Following Complicated Central Line Insertion Leads to Cardiac Arrest

The use of grape juice in the detection of esophageal leaks.

BackgroundEsophagectomies and repair of esophageal perforations are operations used for a variety of clinical indications. Anastomotic leaks are a major post-operative complication after these procedures. At our institution, we routinely use grape juice to detect esophageal leaks in the post-operative setting in addition to other standard imaging modalities. We hypothesize that grape juice can provide similar diagnostic sensitivity and specificity to other modalities for leak detection.MethodsA retrospective review of all patients who underwent an esophagectomy or repair of esophageal perforations from 2013–2019 by the thoracic surgery service at our institution was performed. All patients underwent a barium swallow study, CT imaging or upper endoscopy, as well as ingesting purple grape juice on post-operative day 5 or greater. Purple grape juice observed in the tube thoracostomy drainage system was identified as a positive esophageal leak.ResultsSixty-four patients were included in the study period (25% female, 88% white, median age 62 years old). Sixty-three patients had both a barium swallow study and grape juice test, while one patient underwent CT imaging and grape juice study. Grape juice test sensitivity and specificity were found to be 80% and 98.3%, respectively.ConclusionsThis pilot study demonstrates the effectiveness of using grape juice in detecting esophageal leaks after esophageal operations in patients with tube thoracostomies. Grape juice may be cheaper and potentially less morbid than other studies performed to detect esophageal leaks. Further research is needed to justify the increased use of grape juice in patients who undergo esophageal operations.

Open thoracotomy and decortication for chronic empyema thoracis: Our experience

Empyema thoracis is defined as the presence of pus in the pleural space or a purulent pleural effusion. Chronic empyema is characterized by thickened visceral and parietal peels, which hamper the ability of the affected lung to re-expand and require definitive surgical intervention. In a resource constraint environment like ours, open thoracotomy and decortication is the treatment of choice. We review our experience with cases of chronic empyema thoracis that had thoracotomy and decortication. This is a descriptive, retrospective, and observational study. Medical records of patients who had thoracotomy and decortication on account of chronic empyema thoracis in the Cardiothoracic surgery unit of our hospital between 2012 and 2020 were retrieved and reviewed. The information obtained from the records included sex, age, premorbid conditions, aetiology of empyema, cultures of pleural fluids, histology results of the cortex removed, duration of chest tube drainage, duration of hospital stay, postoperative complications, and outcome. One hundred and eighty-five patients diagnosed with empyema thoracis were seen in the study period. Sixty-five patients had thoracotomy and decortication on account of chronic empyema thoracis while the remaining 120 (64.9%) had closed tube thoracostomy drain insertion. Male: female was 5:1, mean age at presentation 24.24 years with age ranging from 2 years to 70 years. Fourteen (23.33%) were in the paediatric age group while the remaining (76.67%) were adults. The aetiology of empyema was pneumonia in 36 (60%). Strept pneumoniae was the commonest organism isolated from pleural fluids of these patients accounting for 23.33%. All patients underwent thoracotomy and decortication. The mean duration before surgery was 17 days with a range of 2 days to 40 days. The average duration of surgery was 2 hours. Chest tube was removed after an average of 7 days (range 5 to 33 days. Twenty-one patients (35%) had complications. The average duration of drainage was 18.87 days and that of hospital stay was 36.74 days. There were 3 mortalities (5%). The mean duration of follow-up was 3 months. Chronic empyema thoracis is still common in our environment and presentation is usually very late. In our series, open thoracotomy and decortication was found to be an excellent procedure with low morbidity and mortality. The majority of our patients had good functional outcome with few complications.

Incidence, Management, and Outcomes of Patients With COVID-19 and Pneumothorax

BackgroundOur objective was to report the incidence, management, and outcomes of patients who developed a secondary pneumothorax while admitted for coronavirus disease 2019 (COVID-19). MethodsA single-institution, retrospective review of patients admitted for COVID-19 with a diagnosis of pneumothorax between March 1, 2020, and April 30, 2020, was performed. The primary assessment was the incidence of pneumothorax. Secondarily, we analyzed clinical outcomes of patients requiring tube thoracostomy, including those requiring operative intervention. ResultsFrom March 1, 2020, to April 30, 2020, 118 of 1595 patients (7.4%) admitted for COVID-19 developed a pneumothorax. Of these, 92 (5.8%) required tube thoracostomy drainage for a median of 12 days (interquartile range 5-25 days). The majority of patients (95 of 118, 80.5%) were on mechanical ventilation at the time of pneumothorax, 17 (14.4%) were iatrogenic, and 25 patients (21.2%) demonstrated tension physiology. Placement of a large-bore chest tube (20 F or greater) was associated with fewer tube-related complications than a small-bore tube (14 F or less) (14 vs 26 events, P = .011). Six patients with pneumothorax (5.1%) required operative management for a persistent alveolar-pleural fistula. In patients with pneumothorax, median hospital stay was 36 days (interquartile range 20-63 days) and in-hospital mortality was significantly higher than for those without pneumothorax (58% vs 13%, P < .001). ConclusionsThe incidence of secondary pneumothorax in patients admitted for COVID-19 is 7.4%, most commonly occurring in patients requiring mechanical ventilation, and is associated with an in-hospital mortality rate of 58%. Placement of large-bore chest tubes is associated with fewer complications than small-bore tubes.

Empyema thoracis in a Nigerian neonate: case report and brief literature review

Empyema thoracis (ET) is a significant cause of paediatric hospital admissions and mortality but an infrequent finding in the neonatal period. Our case was a three week old male who presented with respiratory distress and had empyema thoracis. He was managed successfully with antibiotics and chest tube thoracostomy drainage.

Management of Spontaneous Pneumothorax in Pregnancy in a Low-Income Country During COVID-19 Pandemic

Spontaneous pneumothorax is a rare and life-threatening emergency. When it occurs in pregnancy, it poses a serious danger for both the mother and the fetus. A high index of suspicion, early diagnosis, and proper management are recommended. We present the case of a 35-year-old pregnant woman at the 34th week of gestation who presented via the emergency department complaining of sudden onset of dyspnea and chest pain. The clinical and radiologic evaluation confirmed the right-sided pneumothorax. She had a closed tube thoracostomy drainage (CTTD) following which the patient's condition improved. She subsequently had chest tube removal with no recurrence beyond delivery as she had a good outcome.

Clinical application of a digital thoracic drainage system for objectifying and quantifying air leak versus the traditional vacuum system: a retrospective observational study.

BackgroundDigital thoracic drainage systems have recently been introduced and widely used in clinical practices in developed countries. These systems can monitor intrathoracic pressure changes and air leaks in real time, and also allow for objective and quantitative analyses, which aid in managing patients with a prolonged persistent air leak into the pleural space. We investigated the feasibility and effectiveness of such a new device versus the traditional vacuum system for treating patients with pneumothorax.MethodsClosed thoracostomy drainage was carried out on 100 adult patients with primary or secondary pneumothorax between January 2017 and December 2018. All the patients were aged ≥18 years and treated with a chest tube at a single medical center by the same cardiothoracic surgeons and intensivists. Patients who underwent closed thoracostomy drainage using an indwelling 24-French chest tube were divided into 2 groups immediately before closed thoracostomy: the digital thoracic drainage group (digital group, n=50) and the traditional analogue thoracic drainage group (analogue group, n=50). The detailed information about demographic data, treatment outcome, duration of indwelling catheterization., hospital days, cost-effectiveness and patient satisfaction was evaluated. We also evaluated whether digitally recorded intrapleural pressure changes and air leaks would predict chest tube removal timing and outcome.ResultsThe baseline parameters of the 2 groups were comparable with no significant differences in sex, age, weight or body mass index. The mean hospital day was shorter in the digital group than in the analogue group (17.96±12.23 vs. 18.32±16.64, P=0.902), and there was no statistically significant difference in the hospital length of stay between the 2 groups. Air leaks through the chest tube and duration of chest tube indwelling hours showed no significant statistical differences between the digital and analogue groups (213.47±219.80 vs. 261.94±184.47, P=0.235 and 223.44±218.75 vs 275.29±186.06, P=0.205, respectively). Total drainage amount and ambulation time per day were significantly higher in the digital group than in the analogue group [209.62±139.63 vs. 162.48±80.42 (P=0.042) and 6.42±3.62 vs.3.94±1.74 (P<0.001), respectively]. Hours of full expansion were significantly shorter and sleep disturbance caused by the noise of chest tube drainage was less in the digital group than in the analogue group [25.64±14.55 vs. 46.52±25.53 (P<0.001) and 2.38±1.03 vs. 5.70±2.87 (P<0.001), respectively].ConclusionsTo date, there is no definite consensus and guidelines on the standardized digital suction system in pneumothorax. This study proposed the guidelines for the application of digital thoracic drainage systems in pneumothorax and also suggested that digital thoracic drainage systems might be a valuable tool to determine chest tube removal timing and reducing the length of hospital stay in patients with pneumothorax.

CLOSURE OF A BRONCHOPLEURAL FISTULA WITH ONE-WAY ENDOBRONCHIAL VALVES WHILE ON HIGH-FREQUENCY OSCILLATORY VENTILATION

SESSION TITLE: Medical Student/Resident Critical Care Posters SESSION TYPE: Med Student/Res Case Rep Postr PRESENTED ON: October 18-21, 2020 INTRODUCTION: A bronchopleural fistula (BPF) is an abnormal sinus tract between the tracheobronchial tree and the pleural space whose presence is associated with increased morbidity, mortality and extended hospital duration. Additionally, a large airway defect can result in refractory hypercapnia rendering periprocedural ventilation exceedingly difficult. Preferred definitive management is surgical resection. However, for the non – surgical candidate a handful of bronchoscopic and pleural interventions, including compassionate placement of one – way valves, have been successfully described for the treatment of a persistent BPF. CASE PRESENTATION: A 25 – year old male with restrictive lung disease secondary to severe muscular dystrophy was admitted to a surgical ICU after a difficult intubation resulting in an emergent cricothyroidotomy and placement of two unilateral surgical chest tubes. The patient’s underlying lung disease combined with intra-parenchymal placement of one of the chest tubes resulted in mixed respiratory failure. Multiple modes of conventional ventilation with neuromuscular blockade were trialed with persistent life threatening hypercapnia prior to being stabilized on a High – Frequency Oscillatory Ventilator (HFOV). His clinical course was complicated by bacteremia, fungemia and a large continuous air-leak. On bronchoscopy, the right upper lobe (RUL) was identified as the anatomic origin of the defect following occlusion with a 5.5 Fr Fogarty Balloon catheter and resolution of the air leak. Definitive management was attempted by placement of four one – way Spriation endobronchial values within the RUL segments while concurrently on HFOV. Significant decrement of the air leak was successfully obtained as well as improvement of his oxygenation and ventilation. DISCUSSION: Chest trauma, including inadvertent intra – parenchymal placement of a chest tube is a rare cause of a bronchopleural fistula. We describe a case of a BPF complicated by a large persistent air leak with initial management via ventilation on a high frequency oscillatory ventilator followed by a novel attempted at definitive treatment with placement of endobronchial values while concurrently on HFOV. CONCLUSIONS: Compassionate placement of endobronchial one – way vales can be safely executed while on HFOV for management of a severe BPF in non – surgical candidates. Reference #1: Gilbert, C.

ASPERGILLUS FUMIGATUS EMPYEMA IN AN IMMUNOCOMPROMISED PATIENT WITH RHEUMATOID ARTHRITIS

SESSION TITLE: Medical Student/Resident Chest Infections Posters SESSION TYPE: Med Student/Res Case Rep Postr PRESENTED ON: October 18-21, 2020 INTRODUCTION: Fungal empyema is a rare entity (less than 1 percent of all cases) with Candida spp. being the most common etiological agents and only a few cases due to Aspergillus spp (1). CASE PRESENTATION: A 74-year-old male with history of rheumatoid arthritis on maintenance prednisone and methotrexate presented with progressive exertional shortness of breath and productive cough for 3 months. Chest X-ray showed a large left pleural collection with air-fluid level and thick wall. Computed tomography (CT) of the chest showed a large pleural loculation with an air fluid level surrounded by thickened wall, consolidation of the left lower lobe, and scattered tree-in-bud opacities bilaterally. A small right pleural effusion with multiple benign appearing pulmonary nodules was also noted. Video-assisted thoracoscopic surgery (VATS) with decortication was done. Pleural biopsy showed a dense mat of branching, septated fungal hyphae involving necrotic pleura. Pleural fluid cultures grew Aspergillus fumigatus. IV liposomal amphotericin was started, caused hypotension, was changed to IV voriconazole which led to acute liver injury and was eventually treated with micafungin. Repeat cultures from thoracostomy drainage grew Streptococcus viridans and Neisseria flava. They were suspected to have seeded from a bronchopleural fistula and IV piperacillin-tazobactam was given for coverage. The hospital course was complicated by left sided pneumothorax post-VATS requiring reinsertion of chest tube, atrial fibrillation with rapid ventricular rate, dysphagia and right sided pleural effusion requiring diagnostic thoracentesis (exudative fluid with negative culture). Patient requested discontinuation of medical therapy and transition to comfort measures due to his extended hospital stay. He was eventually transferred to hospice. DISCUSSION: Among the Aspergillus empyema cases, A. fumigatus is isolated most often, though other spp., such as A. flavus and A. terreus, have also been implicated (2). Fifty percent of such cases are polymicrobial. Risk factors include immunocompromised state and conditions predisposing to bronchopleural fistula (tuberculosis, sarcoidosis, cavitary pneumonia, thoracic surgery, pneumonectomy and lung transplantation). Diagnosis is made from pleural fluid culture or pleural biopsy stains showing characteristic hyphae. Pleural fluid is generally turbid with high protein, low glucose, increased neutrophils and galactomannan. Treatment is combined surgical (drainage of the pleural cavity, necrotic tissue resection and closure of bronchopleural fistula) and prolonged systemic antifungal therapy with triazoles (first line) or echinocandins (salvage therapy for treatment failure or tolerability concerns) (3). CONCLUSIONS: Aspergillus empyema is a rare but highly morbid entity that should be considered in immunocompromised hosts and requires surgical and prolonged medical management.

Predictors of retained hemothorax in trauma: Results of an Eastern Association for the Surgery of Trauma multi-institutional trial.

The natural history of traumatic hemothorax (HTX) remains unclear. We aimed to describe outcomes of HTX following tube thoracostomy drainage and to delineate factors that predict progression to a retained hemothorax (RH). We hypothesized that initial large-volume HTX predicts the development of an RH. We conducted a prospective, observational, multi-institutional study of adult trauma patients diagnosed with an HTX identified on computed tomography (CT) scan with volumes calculated at time of diagnosis. All patients were managed with tube thoracostomy drainage within 24 hours of presentation. Retained hemothorax was defined as blood-density fluid identified on follow-up CT scan or need for additional intervention after initial tube thoracostomy placement for HTX. A total of 369 patients who presented with an HTX initially managed with tube thoracostomy drainage were enrolled from 17 trauma centers. Retained hemothorax was identified in 106 patients (28.7%). Patients with RH had a larger median (interquartile range) HTX volume on initial CT compared with no RH (191 [48-431] mL vs. 88 [35-245] mL, p = 0.013) and were more likely to be older with a higher burden of thoracic injury. After controlling for significant differences between groups, RH was independently associated with a larger HTX on presentation, with a 15% increase in risk of RH for each additional 100 mL of HTX on initial CT imaging (odds ratio, 1.15; 95% confidence interval, 1.08-1.21; p < 0.001). Patients with an RH also had higher rates of pneumonia and longer hospital length of stay than those with successful initial management. Retained hemothorax was also associated with worse functional outcomes at discharge and first outpatient follow-up. Larger initial HTX volumes are independently associated with RH, and unsuccessful initial management with tube thoracostomy is associated with worse patient outcomes. Future studies should use this experience to assess a range of options for reducing the risk of unsuccessful initial management. Therapeutic/care management study, level III.

Emergency Physician-Administered Sedation for Thoracostomy in Children With Pleuropneumonia.

Thoracostomy drainage is sometimes required in children with pleuropneumonia who have large parapneumonic effusion. This procedure is usually performed under sedation. The aim was to report sedation adverse events (SAEs) in pneumonia patients sedated for thoracostomy by pediatric emergency physicians. A retrospective cohort study was conducted. The medical records of all emergency department patients who underwent thoracostomy between January 1, 2012, and December 31, 2018, were extracted. Study outcomes were SAEs that required intervention. Pigtail catheters were placed by chest surgeons in 28 children with a median age of 2 years (interquartile range [IQR], 1-5 years). All the thoracostomies were successfully performed under sedation performed by 11 pediatric emergency physicians. The median amount of fluid drained after catheter insertion was 200 mL (IQR, 100-500 mL). The median pleural fluid PH was 7.0 (IQR, 6.9-7.3), and the median white blood cell count was 34,600 per mm3 (IQR, 11,800-109,000 per mm3). Thirteen patients (46.4%) were sedated with a total median dose of 3 mg/kg of ketamine (IQR, 2-4 mg/kg) and 0.2 mg/kg of midazolam (IQR, 0.2-0.3 mg/kg); 11 patients (39.3%) were treated with 1 mg/kg of ketamine (IQR, 0.5-2 mg/kg) and 3 mg/kg of propofol (IQR, 2-4 mg/kg). Four patients (14.3%) were treated exclusively with 4 mg/kg of ketamine (IQR, 3-5 mg/kg). Nine oxygen desaturations required intervention; 1 was associated with laryngospasm and 1 with apnea. All the SAEs were successfully managed. No cases of hypotension, bradycardia, airway obstruction, or pulmonary aspiration were recorded. The first series of pneumonia patients sedated for thoracostomy by pediatric emergency physicians is reported. Sedation was safely performed in this cohort.

Pediatric Thoracic Empyema-Outcomes of Intrapleural Thrombolytics: Ten Years of Experience.

Introduction. Pediatric thoracic empyema is a special entity with increasing frequency. Consensus regarding the best management strategy is still evolving. We describe our single-center 10-year experience adopting intrapleural thrombolytics using tissue plasminogen activator as first-line treatment following failure of simple thoracostomy drainage techniques. Methods. Observational prospective study included all children from 1 day to 18 years admitted for parapneumonic effusion and treated with intrapleural thrombolytics. Results. From January 2008 to December 2018, 95 patients were treated by intrapleural thrombolytics for different stages of empyema thoracis. Number of thrombolytic doses required is 2.1 (range = 1-3), and mean amount of drainage is 1050 mL (range = 400-2500 mL). Mean total days of hospitalization is 7.3 days. Complete re-expansion was the primary outcome in 94 patients (98.9%). Conclusion. Intrapleural thrombolytics in complicated pediatric thoracic empyema results in excellent outcome and should be encouraged particularly in limited resource countries.

The use of small-bore wire-guided chest drains for the management of feline pyothorax: A retrospective case series.

Background:Pyothorax in cats is routinely managed, at least initially, with thoracic tube placement associated with systemic antimicrobial administration. Traditionally, large-bore trocar-type thoracostomy tubes have preferentially been used for the drainage of thick material from the pleural space. In recent years, the use of small-bore wire-guided thoracic drains has increased in both small animals and in humans. Few studies have highlighted the efficacy of small-bore wire-guided thoracostomy tubes.Aim:The purpose of this study was to describe the use of small-bore wire-guided thoracostomy tubes in feline pyothorax in terms of efficacy, safety, and outcome.Methods:Cats with pyothorax managed with small-bore thoracostomy tubes (SBTTs) (2015–2018) were retrospectively studied. The number of drains inserted, the need for anesthesia and analgesia for chest tube placement and maintenance, and related major and minor complications were reviewed. Clinical data, diagnostic results, treatment, and outcome were recorded.Results:Ten cats were enrolled. Thoracostomy tube placement was unilateral in 7/10 cats, despite the presence of bilateral effusion in 9/10 cats, and required sedation (8/10) or anesthesia (2/10). Three cats experienced minor complications during the chest tube insertion, including self-limiting pneumothorax (1/3) and malpositioning (2/3). One cat had a major complication (non-functional malposition) requiring reposition of the drain. Pain management was adequately achieved using opioids (8/10) or opioids plus nonsteroidal anti-inflammatory drugs (2/10). Partial chest tube occlusion occurred in three cases and it was resolved with lavage. In one case, the occlusion was complete, requiring drain removal. Three out of 10 cats were treated medically, combining thoracostomy tubes and antibiotics, while 7/10 cats underwent surgery. All the cats survived.Conclusion:SBTTs represent a safe and effective option for the initial management of feline pyothorax. In fact, mainly minor complications were reported during insertion and usage. The SBTTs were well tolerated by the cats with a satisfactory performance in terms of exudate drainage in most cases. The combined use of a small-bore thoracostomy drain together with the common practice of surgical treatment might have resulted in the successful management of the cases presented.

Adequacy of hemostatic resuscitation improves therapeutic efficacy of recombinant activated factor VII and reduces reexploration rate for bleeding in postoperative cardiac surgery patients with refractory hemorrhage.

Background:Excessive bleeding and surgical reexploration are common complications that increase the risk of multi-organ failure and prolonged hospitalization after cardiac surgery. Off-label use of recombinant activated factor VII (rFVIIa) is a recommended treatment for refractory bleeding.Objective:The objective of the study is to determine if the adequacy of hemostatic resuscitation enhances the efficacy of rFVIIa.Methods:This retrospective, observational, cohort study included patients who received rFVIIa for refractory postoperative bleeding after cardiac surgery. Patients were divided into two groups based on the presence or absence of adequate coagulation resuscitation before rFVIIa administration, defined as international ratio (INR) ≤1.5, platelet count ≥100 K/mL, and fibrinogen ≥200 mg/dL. The failure of rFVIIa treatment was defined as surgical reexploration within 24 h, thoracostomy drainage >400 mL/h within 6 h or transfusion of additional blood products or another rFVIIa dose within 6 h after initial rFVIIa dose.Results:Of the 3833 patients, screened who underwent cardiothoracic surgery procedures, 58 patients received rFVIIa for refractory postoperative bleeding. Successful hemostasis with rFVIIa was more likely in patients who were adequately resuscitated compared with those who were not (20 [71.4%] vs. 10 [33.3%], respectively; P = 0.0046). Multiple logistic regression analysis indicated that patients who were adequately resuscitated before rFVIIa were less likely to fail treatment (odds ratio, 0.16; 95% confidence interval [0.04–0.62]; P = 0.007).Conclusions:The therapeutic efficacy of rFVIIa is dependent on the adequacy of hemostatic resuscitation; restoration of normal serum fibrinogen, INR, and platelet counts >100 K/mL may provide an adequate substrate for rFVIIa to be effective in managing refractory postoperative cardiac surgical bleeding.
