Pleural pigtail catheter placement is associated with many complications including pneumothorax, hemorrhage, and chest pain. Air embolism is a known but rare complication of pleural pigtail catheter insertion and has a high risk of occurrence with positive pressure ventilation. In this case report, we present a 50-year-old male with bilateral pneumonia who developed a pneumothorax while on mechanical ventilation with continuous positive airway pressure mode. During the placement of the pleural p ...[more]

Project description:Background: Chest tube insertion is a standard intervention for management of various injuries of the thorax. Efficient clinical training of this and similar bed-side procedures is equally demanded and improvable. Here, we propose a nouveau means of assessment and feedback using an Objective Structured Assessment of Technical Skills (OSATS) tool. The modified OSATS for chest drain insertion is evaluated in a pilot trial focusing on chest drain insertion. Methods: Participants in the pilot trial were medical students (3rd-6th year of studies, n=9), junior residents (1st-3rd post-graduate year, n=12), senior residents (4th-6th post-graduate year, n=14), and attending surgeons (n=6) from Heidelberg University. Chest drain insertions on a cadaveric porcine model were rated by experts with the modified OSATS score. Participants' performances were videotaped and subsequently rated by two remote experts (video rating). Primary aim was to assess criterion validity of the OSATS to distinguish experience levels. Results: Kruskal-Wallis test showed significant differences between means of scores between four groups stratified by previous experience in chest tube insertion (level 0: 22.1±3.2 vs. level 1: 26.8±2.8 vs. level 2: 35.4±2.2 vs. level 3: 41.0±2.0; p=0.002; p1,3=0.049, p0,3=0.005). However, if groups were stratified by formal professional level, no statistically significant distinction could be made using OSATS. Hence, the OSATS tool showed criterion validity for differentiation between experience levels. Conclusion: In the pilot study, the modified OSATS for chest tube insertion was apt to standardize expert rating and could be used to measure skill and to depict different experience levels. The OSATS will help facilitate training and assessment of chest drain insertion and could therefore improve surgical training for trauma situations. According to our data, the OSATS might be integrated into modern curricula.

Project description:In this study we explored whether one pleural catheter plus single chest tube drainage could achieve a noninferior drainage effect when compared with the traditional two chest tubes in uniportal video-assisted thoracoscopic surgery (VATS) for an upper pulmonary lobectomy. Patients that underwent an upper pulmonary lobectomy from January to November 2020 were enrolled in this single-center, randomized, open-label, noninferiority trial. Prior to closure, patients were randomized to an intervention group who received an improved drainage strategy involving one pleural catheter with one chest tube (24 Fr), while traditional double chest tube drainage was applied for the control group. A total of 390 patients entered the study, although 190 were excluded for changing nonuniportal surgical approaches or opting for nonlobectomy resections. Finally, 200 patients were randomized (100 in the intervention group and 100 in the control group). The baseline demographic and clinical characteristics were comparable between the groups. The incidence of pneumothorax in the intervention and control groups was similar on postoperative Day 1 (noninferiority, 10% vs. 13%, p = 0.658). In addition, there were no significant differences in secondary outcomes such as incidence of pneumothorax by Day 30, postoperative chest tube/pleural catheter removal time, amount of drainage on Day 1, total amount of drainage after operation, or postoperative hospitalization. A significantly lower pain score was observed in the intervention group (3.33 ± 0.68 vs. 3.68 ± 0.94, p = 0.003). The new strategy is noninferior to double chest tube drainage after an upper pulmonary lobectomy offers superior pain control, and is recommended for an upper lobectomy by uniportal VATS.

Project description:IntroductionTube thoracostomy (TT), considered a routine procedure, has significant complications. Current recommendations for placement rely on surface anatomy. There is no information to guide operators regarding angle of insertion relative to chest wall. We aim to determine if angle of insertion is associated with complications of TT.MethodsWe performed a retrospective review of adult trauma patients who necessitated TT at a Level I trauma center over a 2-year period (January 2012 to December 2013). Tube thoracostomies performed intraoperatively or using radiological guidance were excluded. Thoracic anteroposterior or posteroanterior radiographs were reviewed to determine the angle of insertion of TT relative to the thoracic wall. A previously validated classification method was used to categorize complications. Descriptive and univariate statistics were used to compare angle of insertion and complicated versus uncomplicated TT.ResultsReview identified 154 patients who underwent a total of 246 TT placed for emergent trauma. All patients had a postprocedural chest x-ray. We identified 90 complications (37%) over the study period. One hundred forty-four of the TTs reviewed had an angle of insertion less than 45 degrees of which there were 27 complications (19%). One hundred two of the TTs had an angle greater than 45 degrees and 63 complications (62%); p < 0.0001.ConclusionsTube thoracostomy insertion is inherently dangerous. Placement of TT using a higher angle of insertion greater than 45 degrees is associated with increased complications. Further prospective studies quantifying TT angle of insertion on outcomes are needed.Level of evidenceTherapeutic study, level IV.

Project description:Background Although chest tube-omitted video-assisted thoracoscopic surgery (VATS) has been proven to be safe and efficacious, its universal application is precluded by a varying morbidity rate due to a lack of standardization. Since digital chest drainage has already shown improved accuracy and consistency in the management of postoperative air leak, we incorporated it in the strategy of intraoperative chest tube withdrawal, aiming to achieve better results. Methods We collected the clinical data of 114 consecutive patients who underwent elective uniportal VATS pulmonary wedge resection at the Shanghai Pulmonary Hospital from May 2021 to February 2022. Their chest tubes were withdrawn intraoperatively after an air-tightness test facilitated by digital drainage: the end flow rate had to be kept ≤30 mL/min for >15 s at the setting of −8 cmH2O suctioning. The recordings and patterns of the air suctioning process were documented and analyzed as potential standards of chest tube withdrawal. Results The mean age of the patients was 49.7±11.7 years. The mean size of the nodules was 1.0±0.2 cm. The location of the nodules encompassed all lobes, and 90 (78.9%) patients received preoperative localization. The postoperative morbidity and mortality rates were 7.0% and 0%, respectively. Six patients had clinically overt pneumothorax and two patients had postoperative bleeding that required intervention. All of the patients recovered on conservative treatment except for one case of pneumothorax that required additional tube thoracostomy. The median length of postoperative stay was 2 days; and the median time of suctioning, peak flow rate, and end flow rate were 126 s, 210 mL/min, and 0 mL/min, respectively. The median numeric rating scale for pain was 1 on postoperative day (POD) 1 and 0 on the day of discharge. Conclusions Chest tube-free VATS assisted by digital drainage is feasible with minimal morbidity. Its strength of quantitative air leak monitoring produces important measurements for the prediction of postoperative pneumothorax and future standardization of the procedure.

Project description:BackgroundVenous air embolism is a potentially life-threatening complication of IV catheter use in horses. Despite widespread anecdotal reports of their occurrence, few cases have been reported in the literature and the prognosis is currently unknown.Hypothesis/objectivesOur objective was to describe the surrounding circumstances, clinical signs, treatment, progression, and outcome of venous air embolism in hospitalized horses.AnimalsThirty-two horses with acute onset of compatible clinical signs associated with IV catheter disconnection or damage.MethodsMulticenter retrospective study. Data extracted from clinical records included signalment, presenting complaint, catheter details, clinical signs, treatments, and outcome.ResultsMost cases resulted from extension set disconnection occurring within approximately 24 hours after catheter placement. In fewer horses, extension set damage was cited as a cause. Common clinical signs included tachycardia, tachypnea, recumbency, muscle fasciculations and agitation, with abnormal behavior including kicking and flank biting. Less commonly, pathological arrhythmias or more severe neurologic signs, including blindness and seizures, were noted. Progression was unpredictable, with some affected horses developing delayed-onset neurologic signs. Mortality was 6/32 (19%), including 2 cases of sudden death and other horses euthanized because of persistent neurologic deficits. Negative outcomes were more common in horses with recorded blindness, sweating or recumbency, but blindness resolved in 5/8 affected horses.Conclusions and clinical importanceThe prognosis for resolution of clinical signs after air embolism is fair, but permanent neurologic deficits or pathologic cardiac arrhythmias can arise. Unpredictable progression warrants close monitoring. Systematic clinic-based surveillance could provide additional useful information to aid prevention.

Project description:ObjectiveTo determine which bedside method of detecting inadvertent endobronchial intubation in adults has the highest sensitivity and specificity.DesignProspective randomised blinded study.SettingDepartment of anaesthesia in tertiary academic hospital.Participants160 consecutive patients (American Society of Anesthesiologists category I or II) aged 19-75 scheduled for elective gynaecological or urological surgery.InterventionsPatients were randomly assigned to eight study groups. In four groups, an endotracheal tube was fibreoptically positioned 2.5-4.0 cm above the carina, whereas in the other four groups the tube was positioned in the right mainstem bronchus. The four groups differed in the bedside test used to verify the position of the endotracheal tube. To determine whether the tube was properly positioned in the trachea, in each patient first year residents and experienced anaesthetists were randomly assigned to independently perform bilateral auscultation of the chest (auscultation); observation and palpation of symmetrical chest movements (observation); estimation of the position of the tube by the insertion depth (tube depth); or a combination of all three (all three).Main outcome measuresCorrect and incorrect judgments of endotracheal tube position.Results160 patients underwent 320 observations by experienced and inexperienced anaesthetists. First year residents missed endobronchial intubation by auscultation in 55% of cases and performed significantly worse than experienced anaesthetists with this bedside test (odds ratio 10.0, 95% confidence interval 1.4 to 434). With a sensitivity of 88% (95% confidence interval 75% to 100%) and 100%, respectively, tube depth and the three tests combined were significantly more sensitive for detecting endobronchial intubation than auscultation (65%, 49% to 81%) or observation(43%, 25% to 60%) (P<0.001). The four tested methods had the same specificity for ruling out endobronchial intubation (that is, confirming correct tracheal intubation). The average correct tube insertion depth was 21 cm in women and 23 cm in men. By inserting the tube to these distances, however, the distal tip of the tube was less than 2.5 cm away from the carina (the recommended safety distance, to prevent inadvertent endobronchial intubation with changes in the position of the head in intubated patients) in 20% (24/118) of women and 18% (7/42) of men. Therefore optimal tube insertion depth was considered to be 20 cm in women and 22 cm in men.ConclusionLess experienced clinicians should rely more on tube insertion depth than on auscultation to detect inadvertent endobronchial intubation. But even experienced physicians will benefit from inserting tubes to 20-21 cm in women and 22-23 cm in men, especially when high ambient noise precludes accurate auscultation (such as in emergency situations or helicopter transport). The highest sensitivity and specificity for ruling out endobronchial intubation, however, is achieved by combining tube depth, auscultation of the lungs, and observation of symmetrical chest movements.Trial registrationNCT01232166.

Project description:The sensitivity of postoperative pleural air leakage (PAL) after pulmonary resection is evaluated by a simple subjective grading method in clinical practice. A new electronic digital chest drainage evaluation system (DCS) recently became clinically available. This study was designed to evaluate the clinical application of the DCS in monitoring the airflow volume and managing postoperative PAL.We prospectively enrolled 25 patients who underwent pulmonary resection. Postoperative PAL was evaluated using both conventional PAL grading based on the physician's visual judgment (analog chest drainage evaluation system [ACS]: Level 0 = no leakage to 4 = continuous leakage) and the DCS. The DCS digital measurement was recorded as the flow volume (ml/min), which was taken once daily from postoperative day 1 to the day of chest drainage tube removal.In total, 45 measurements were performed on 25 patients during the evaluation period. Postoperative PAL was observed in five patients (20.0%) and judged as ACS Level >1. The mean DCS values corresponding to ACS Levels 0, 1, 2, and 3 were 2.42 (0.0-11.3), 48.6 (35.4-67.9), 95.6 (79.7-111.5), and 405.3 (150.3-715.6), respectively. The Spearman correlation test showed a significant positive correlation between the ACS PAL level and DCS flow volume (R = 0.8477, p < 0.001).A relationship between the visual PAL level by the ACS and the digital value by the DCS was identified in this study. The numeric volume obtained by the DCS has been successful in information-sharing with all staff. The digital PAL value evaluated by the DCS is appropriate, and the use of the DCS is promising in the treatment of postoperative PAL after pulmonary resection.

Project description:BackgroundIn video-assisted thoracoscopic surgery for spontaneous pneumothorax, the initial trocar can be inserted into the pleurocutaneous fistula formed during preoperative chest drain placement. The use of an optical-access trocar to replace the initial trocar and chest tube may have a greater success rate than blind trocar insertion. Therefore, the present study aimed to evaluate the safety and feasibility of the use of an optical-access trocar to replace the initial trocar and chest tube during surgery for spontaneous pneumothorax.MethodsThe present study included 28 patients who underwent video-assisted thoracoscopic surgery for spontaneous pneumothorax following preoperative chest drain placement between April, 2017 and December, 2019. At the start of surgery, the chest drain was removed and the initial trocar was inserted into the pleural cavity. An optical-access trocar with an inner diameter of 5 mm was used as the initial trocar. To use a 0-degree endoscope for the optical-access trocar, this procedure requires the preparation of both, a 0-degree endoscope and a 30-degree endoscope. To evaluate the safety of the optical view method, the lungs and chest wall adjacent to the initial trocar insertion site were observed from the second trocar.ResultsThe initial trocar could be inserted through the chest tube insertion site in 26 out of 28 cases (92.9%). No instances of lung injury or pulsatile bleeding around the initial trocar were observed. No cases of postoperative wound infection or wound dehiscence were observed.ConclusionsThe use an optical-access trocar as the initial trocar when replacing a preoperatively placed chest tube is safe and feasible during video-assisted thoracoscopic surgery for spontaneous pneumothorax.

Project description:The aim of this study was to evaluate the risk of pneumothorax and need for chest tube insertion in CT-guided lung biopsies and identify predictors focusing on pulmonary emphysema determined with quantitative computed tomography. To that end, we retrospectively analysed the incidence of pneumothorax and chest tube insertion in 371 CT-guided lung biopsies with respect to the quantitative emphysema score determined with the density mask technique. Other possible impact factors considered were lesion diameter, length of biopsy pathway within the lung parenchyma, lung lobe, needle size, puncture technique, patient positioning and interventionalist's level of experience. Quantitative emphysema scores of the lung were significantly higher in patients who developed instant pneumothorax (27%, p?<?0.0001), overall pneumothorax (38%, p?=?0.001) and had chest tube insertion (9%, p?=?0.006) compared to those who did not when analysed with the Mann-Whitney U-test. In logistic regression analysis with inclusion of the other possible impact factors, the quantitative emphysema score remained a statistically significant predictor for all three output parameters. This was confirmed with least absolute shrinkage and selection operator (Lasso) regression analysis. In conclusion, quantitatively determined pulmonary emphysema is a positive predictor of the pneumothorax rate in CT-guided lung biopsy and likelihood of chest tube insertion.

Project description:BackgroundThoracoscopic surgery has greatly alleviated the postoperative pain of patients, but postsurgical acute and chronic pain still exists and needs to be addressed. Indwelling drainage tubes are one of the leading causes of postoperative pain after thoracic surgery. Therefore, the aim of this study was to explore the effects of alternative drainage on acute and chronic pain after video-assisted thoracoscopic surgery (VATS).MethodsNinety-two patients undergoing lung wedge resection were selected and randomly assigned to the conventional chest tube (CT) group and the 7-Fr central venous catheter (VC) group. Next, the numeric rating scale (NRS) and pain DETECT questionnaire were applied to evaluate the level and characteristics of postoperative pain.ResultsNRS scores of the VC group during hospitalization were significantly lower than those of the CT group 6 h after surgery, at postoperative day 1, at postoperative day 2, and at the moment of drainage tube removal. Moreover, the number of postoperative salvage analgesics (such as nonsteroidal anti-inflammatory drugs [(NSAIDs]) and postoperative hospitalization days were notably reduced in the VC group compared with the CT group. However, no significant difference was observed in terms of NRS pain scores between the two groups of patients during the follow-up for chronic pain at 3 months and 6 months.ConclusionIn conclusion, a drainage strategy using a 7-Fr central VC can effectively relieve perioperative pain in selected patients undergoing VATS wedge resection, and this may promote the rapid recovery of such patients after surgery.Trial registrationClinicalTrials.gov, NCT03230019.
