Abstract
BACKGROUND The Agency for Healthcare Research and Quality has adopted iatrogenic pneumothorax (IAP) as a Patient Safety Indicator. In 2006, in response to a low performance ranking for IAP rate from the University Healthsystem Consortium (UHC), the authors established a multidisciplinary team to reduce our institution's IAP rate. Root-cause analysis found that subclavian insertion of central venous catheterization (CVC) was the most common procedure associated with IAP OBJECTIVE: Our short-term goal was a 50% reduction of both CVC-associated and all-cause IAP rates within 18 months, with long-term goals of sustained reduction. DESIGN Observational study. SETTING Academic tertiary care hospital. PATIENTS Consecutive inpatients from 2006 to 2014. INTERVENTION Our multifaceted intervention included: (1) clinical and documentation standards based on evidence, (2) cognitive aids, (3) simulation training, (4) purchase and deployment of ultrasound equipment, and (5) feedback to clinical services. MEASUREMENTS CVC-associated IAP, all-cause IAP rate. RESULTS We achieved both a short-term (years 2006 to 2008) and long-term (years 2006 to 2008-2014) reduction in our CVC-associated and all-cause IAP rates. Our short-term reduction in our CVC-associated IAP was 53% (P = 0.088), and our long-term reduction was 85% (P < 0.0001). Our short-term reduction in the all-cause IAP rate was 26% (P < 0.0001), and our long-term reduction was 61% (P < 0.0001). CONCLUSIONS A multidisciplinary team, focused on evidence, patient safety, and standardization, can use a set of multifaceted interventions to sustainably improve patient outcomes for several years after implementation. Our hospital was in the highest performance UHC quartile for all-cause IAP in 2012 to 2014.

Abstract
Vascular cutdown and echo guide puncture methods have its own limitations under certain conditions. There was no available algorithm for choosing entry vessel. A standard algorithm was introduced to help choose the entry vessel location according to our clinical experience and review of the literature. The goal of this study is to analyze the treatment results of the standard algorithm used to choose the entry vessel for intravenous port implantation.During the period between March 2012 and March 2013, 507 patients who received intravenous port implantation due to advanced chemotherapy were included into this study. Choice of entry vessel was according to standard algorithm. All clinical characteristic factors were collected and complication rate and incidence were further analyzed.Compared with our clinical experience in 2006, procedure-related complication rate declined from 1.09% to 0.4%, whereas the late complication rate decreased from 19.97% to 3.55%. No more pneumothorax, hematoma, catheter kinking, fractures, and pocket erosion were identified after using the standard algorithm. In alive oncology patients, 98% implanted port could serve a functional vascular access to fit therapeutic needs.This standard algorithm for choosing the best entry vessel is a simple guideline that is easy to follow. The algorithm has excellent efficiency and can minimize complication rates and incidence.

Abstract
Objective Endoscopic lung volume reduction (ELVR) with valves has been shown to improve COPD patients with severe emphysema. However, a major complication is pneumothoraces, occurring typically soon after valve implantation, with severe consequences if not managed promptly. Based on the knowledge that strain activity is related to a higher risk of pneumothoraces, we asked whether modifying post-operative medical care with the inclusion of strict short-term limitation of strain activity is associated with a lower incidence of pneumothorax. Methods Seventy-two (72) emphysematous patients without collateral ventilation were treated with bronchial valves and included in the study. Thirty-two (32) patients received standard post-implantation medical management (Standard Medical Care (SMC)), and 40 patients received a modified medical care that included an additional bed rest for 48 hours and cough suppression, as needed (Modified Medical Care (MMC)). Results The baseline characteristics were similar for the two groups, except there were more males in the SMC cohort. Overall, ten pneumothoraces occurred up to four days after ELVR, eight pneumothoraces in the SMC, and only two in the MMC cohorts (p=0.02). Complicated pneumothoraces and pneumothoraces after upper lobe treatment were significantly lower in MMC (p=0.02). Major clinical outcomes showed no significant differences between the two cohorts. Conclusions In conclusion, modifying post-operative medical care to include bed rest for 48 hours after ELVR and cough suppression, if needed, might reduce the incidence of pneumothoraces. Prospective randomized studies with larger numbers of well-matched patients are needed to confirm the data.

Abstract
Permanent cardiac pacing has survived a sharp increase in quality improvement and frequency of usage. Nowadays particular aspects of this method of treatment are being considered. In this paper distinctiveness of women population treated by permanent pacing is discussed. Indications for heart pacing in women appear at a later age than in men. Moreover, women remain longer in follow-up, therefore their prognosis is better. The most serious late pacing complications, i.e., infections are less frequent in women. However, implantations procedures seem to be more difficult in female gender, most probably due to a smaller body size, especially of afferent veins. This leads to a higher periprocedural complication rate and refers especially to endocardial lead implantation, which in women is connected with double risk of pneumothorax. Late complications of permanent pacing are effectively treated by transvenous lead extraction. Female gender has been demonstrated as an independent risk factor of extraction failure. It seems that reasonable qualification for pacemaker implantations and leaving the procedures in the hands of experienced operators will strengthen the "light side" and limit the "dark side" of this therapy in women.

Abstract
IMPORTANCE Thoracentesis is performed to identify the cause of a pleural effusion. Although generally safe, thoracentesis may be complicated by transient hypoxemia, bleeding, patient discomfort, reexpansion pulmonary edema, and pneumothorax. OBJECTIVE To identify the best means for differentiating between transudative and exudative effusions and also to identify thoracentesis techniques for minimizing the risk of complications by performing a systematic review the evidence. DATA SOURCES We searched The Cochrane Library, MEDLINE, and Embase from inception to February 2014 to identify relevant studies. STUDY SELECTION We included randomized and observational studies of adult patients undergoing thoracentesis that examined diagnostic tests for differentiating exudates from transudates and evaluated thoracentesis techniques associated with a successful procedure with minimal complications. DATA EXTRACTION AND SYNTHESIS Two investigators independently appraised study quality and extracted data from studies of laboratory diagnosis of pleural effusion for calculation of likelihood ratios (LRs; n = 48 studies) and factors affecting adverse event rates (n = 37 studies). RESULTS The diagnosis of an exudate was most accurate if cholesterol in the pleural fluid was greater than 55 mg/dL (LR range, 7.1-250), lactate dehydrogenase (LDH) was greater than 200 U/L (LR, 18; 95% CI, 6.8-46), or the ratio of pleural fluid cholesterol to serum cholesterol was greater than 0.3 (LR, 14; 95% CI, 5.5-38). A diagnosis of exudate was less likely when all Light's criteria (a ratio of pleural fluid protein to serum protein >0.5, a ratio of pleural fluid LDH to serum LDH >0.6, or pleural fluid LDH >two-thirds the upper limit of normal for serum LDH) were absent (LR, 0.04; 95% CI, 0.02-0.11). The most common complication of thoracentesis was pneumothorax, which occurred in 6.0% of cases (95% CI, 4.0%-7.0%). Chest tube placement was required in 2.0% of procedures (95% CI, 0.99%-2.9%) in which a patient was determined to have radiographic evidence of a pneumothorax. With ultrasound, a radiologist's marking the needle insertion site was not associated with decreased pneumothorax events (skin marking vs no skin marking odds ratio [OR], 0.37; 95% CI, 0.08-1.7). Use of ultrasound by any experienced practitioner also was not associated with decreased pneumothorax events (OR, 0.55; 95% CI, 0.06-5.3). CONCLUSIONS AND RELEVANCE Light's criteria, cholesterol and pleural fluid LDH levels, and the pleural fluid cholesterol-to-serum ratio are the most accurate diagnostic indicators for pleural exudates. Ultrasound skin marking by a radiologist or ultrasound-guided thoracentesis were not associated with a decrease in pneumothorax events.

Abstract
BACKGROUND Malignant pleural effusion (MPE) is an extremely common problem affecting cancer patients, and thoracentesis is an essential procedure in an attempt to delineate the etiology of the fluid collections and to relieve symptoms in affected patients. One of the most common complications of thoracentesis is pneumothorax, which has been reported to occur in 20% to 39% of thoracenteses, with 15% to 50% of patients with pneumothorax requiring tube thoracostomy.The present study was carried out to assess whether thoracenteses in cancer patients performed with ultrasound (US) guidance are associated with a lower rates of pneumothorax and tube thoracostomy than those performed without US guidance. METHODS A total of 445 patients were recruited in this retrospective study. The medical records of 445 consecutive patients with cancer and MPE evaluable for this study, undergoing thoracentesis at the Oncology-Hematology and Internal Medicine Departments, Piacenza Hospital (Italy) were reviewed. RESULTS From January 2005 to December 2011, in 310 patients (69.66%) thoracentesis was performed with US guidance and in 135 (30.34%) without it. On post-thoracentesis imaging performed in all these cases, 15 pneumothoraces (3.37%) were found; three of them (20%) required tube thoracostomy. Pneumothorax occurred in three out of 310 procedures (0.97%) performed with US guidance and in 12 of 135 procedures (8.89%) performed without it (P<0.0001). It must be emphasized that in all three patients with pneumothorax requiring tube thoracostomy, thoracentesis was performed without US guidance. CONCLUSIONS The routine use of US guidance during thoracentesis drastically reduces the rate of pneumothorax and tube thoracostomy in oncological patients, thus improving safety as demonstrated in this study.

Abstract
In many countries increased on-road motorcycling participation has contributed to increased motorcyclist morbidity and mortality over recent decades. Improved helmet technologies and increased helmet wearing rates have contributed to reductions in serious head injuries, to the point where in many regions thoracic injury is now the most frequently occurring serious injury. However, few advances have been made in reducing the severity of motorcyclist thoracic injury. The aim of the present study is to provide needed information regarding serious motorcyclist thoracic trauma, to assist motorcycling groups, road safety advocates and road authorities develop and prioritise counter-measures and ultimately reduce the rising trauma burden. For this purpose, a data collection of linked police-reported and hospital data was established, and considerable attention was given to establishing a weighting procedure to estimate hospital cases not reported to police and fatal cases not admitted to hospital. The resulting data collection of an estimated 19,979 hospitalised motorcyclists is used to provide detailed information on the nature, incidence and risk factors for thoracic trauma. Over the last decade the incidence of motorcyclist serious thoracic injury has more than doubled in the population considered, and by 2011 while motorcycles comprised 3.2% of the registered vehicle fleet, one quarter of road traffic-related serious thoracic trauma cases treated in hospitals were motorcyclists. Motor-vehicle collisions, fixed object collisions and non-collision crashes were fairly evenly represented amongst these cases, while older motorcyclists were over-represented. Several prevention strategies are identified and discussed.

Abstract
The experience of endobronchial valve «Medlung" installation in 24 patients with bronchopleural fistula was summarized in the article. In 18 (75%) patients the cause of bronchopleural fistula was purulent - destructive processes in the lungs, including the associated trauma in 4 (22.2%) patients, pneumonia in 14 (77.8%) patients. In 3 (12.5%) cases the cause of the bronchopleural fistula was the lung tumors of different localization and in 3 (12.5%) cases - idiopathic pulmonary fibrosis. Reasonable use of endobronchial valve in patients with bronchopleural fistula provides a persistent separation of the fistula and lets to avoid extensive, traumatic operations.

Abstract
OBJECTIVE To investigate the risk factors and preventative measures for neonatal pneumothorax. METHODS Retrospective analysis was performed on the clinical data of 2286 neonates who were hospitalized in the neonatal intensive care unit between October 2010 and November 2011, and a case-control study was conducted to analyze the risk factors and preventative measures for neonatal pneumothorax. RESULTS The incidence of pneumothorax among the neonates was 1.57% (36/2286), and it was significantly higher in full-term infants than in preterm infants (23/1033 vs 13/1253, P=0.023). Logistic regression analysis indicated that cesarean section, neonatal respiratory distress syndrome (NRDS), wet lung, pneumonia and mechanical ventilation were the independent risk factors for neonatal pneumothorax (odds ratios=7.951, 6.090, 7.898, 6.272 and 4.389; P<0.05 for all). The higher the peak inspiratory pressure (PIP) during mechanical ventilation, the higher the incidence of neonatal pneumothorax (P<0.001). Pulmonary surfactant reduced the incidence of pneumothorax among neonates with NRDS (2.9% vs 10.1%; P=0.006). CONCLUSIONS Neonatal pneumothorax occurs mostly in full-term infants. Cesarean section, NRDS, wet lung, pneumonia and mechanical ventilation are closely associated with neonatal pneumothorax. Strict management of indications for cesarean section, keeping PIP at a low level during mechanical ventilation, and use of pulmonary surfactant are helpful in preventing neonatal pneumothorax.

Abstract
BACKGROUND Simple aspiration and drainage is a standard initial treatment for primary spontaneous pneumothorax, but the rate of pneumothorax recurrence is substantial. We investigated whether additional minocycline pleurodesis after simple aspiration and drainage reduces the rate of recurrence. METHODS In our open-label, parallel-group, prospective, randomised, controlled trial at two hospitals in Taiwan, patients were aged 15-40 years and had a first episode of primary spontaneous pneumothorax with a rim of air greater than 2 cm on chest radiographs, complete lung expansion without air leakage after pigtail catheter drainage, adequate haematological function, and normal renal and hepatic function. After simple aspiration and drainage via a pigtail catheter, patients were randomly assigned (1:1) to receive 300 mg of minocycline pleurodesis or no further treatment (control group). Randomisation was by computer-generated random numbers in sealed envelopes. Our primary endpoint was rate of pneumothorax recurrence at 1 year. This trial is registered with ClinicalTrials.gov (NCT00418392). FINDINGS Between Dec 31, 2006, and June 30, 2012, 214 patients were randomly assigned-106 to the minocycline group and 108 to the control group (intention-to-treat population). Treatment was unsuccessful within 7 days of randomisation in 14 patients in the minocycline group and 20 patients in the control group. At 1 year, pneumothoraces had recurred in 31 of 106 (29·2%) patients in the minocycline group compared with 53 of 108 (49·1%) in the control group (p=0·003). We noted no procedure-related complications in either group. INTERPRETATION Simple aspiration and drainage followed by minocycline pleurodesis is a safe and more effective treatment for primary spontaneous pneumothorax than is simple aspiration and drainage only. Minocycline pleurodesis should be an adjunct to standard treatment for primary spontaneous pneumothorax. FUNDING Department of Health and National Science Council, Taiwan.

Abstract
BACKGROUND After cardiac surgery, physical therapy is a routine procedure delivered with the aim of preventing postoperative pulmonary complications. OBJECTIVES To determine if preoperative physical therapy with an exercise component can prevent postoperative pulmonary complications in cardiac surgery patients, and to evaluate which type of patient benefits and which type of physical therapy is most effective. SEARCH METHODS Searches were run on the Cochrane Central Register of Controlled Trials (CENTRAL) on the Cochrane Library (2011, Issue 12 ); MEDLINE (1966 to 12 December 2011); EMBASE (1980 to week 49, 2011); the Physical Therapy Evidence Database (PEDro) (to 12 December 2011) and CINAHL (1982 to 12 December 2011). SELECTION CRITERIA Randomised controlled trials or quasi-randomised trials comparing preoperative physical therapy with no preoperative physical therapy or sham therapy in adult patients undergoing elective cardiac surgery. DATA COLLECTION AND ANALYSIS Data were collected on the type of study, participants, treatments used, primary outcomes (postoperative pulmonary complications grade 2 to 4: atelectasis, pneumonia, pneumothorax, mechanical ventilation > 48 hours, all-cause death, adverse events) and secondary outcomes (length of hospital stay, physical function measures, health-related quality of life, respiratory death, costs). Data were extracted by one review author and checked by a second review author. Review Manager 5.1 software was used for the analysis. MAIN RESULTS Eight randomised controlled trials with 856 patients were included. Three studies used a mixed intervention (including either aerobic exercises or breathing exercises); five studies used inspiratory muscle training. Only one study used sham training in the controls. Patients that received preoperative physical therapy had a reduced risk of postoperative atelectasis (four studies including 379 participants, relative risk (RR) 0.52; 95% CI 0.32 to 0.87; P = 0.01) and pneumonia (five studies including 448 participants, RR 0.45; 95% CI 0.24 to 0.83; P = 0.01) but not of pneumothorax (one study with 45 participants, RR 0.12; 95% CI 0.01 to 2.11; P = 0.15) or mechanical ventilation for > 48 hours after surgery (two studies with 306 participants, RR 0.55; 95% CI 0.03 to 9.20; P = 0.68). Postoperative death from all causes did not differ between groups (three studies with 552 participants, RR 0.66; 95% CI 0.02 to 18.48; P = 0.81). Adverse events were not detected in the three studies that reported on them. The length of postoperative hospital stay was significantly shorter in experimental patients versus controls (three studies with 347 participants, mean difference -3.21 days; 95% CI -5.73 to -0.69; P = 0.01). One study reported a reduced physical function measure on the six-minute walking test in experimental patients compared to controls. One other study reported a better health-related quality of life in experimental patients compared to controls. Postoperative death from respiratory causes did not differ between groups (one study with 276 participants, RR 0.14; 95% CI 0.01 to 2.70; P = 0.19). Cost data were not reported on. AUTHORS' CONCLUSIONS Evidence derived from small trials suggests that preoperative physical therapy reduces postoperative pulmonary complications (atelectasis and pneumonia) and length of hospital stay in patients undergoing elective cardiac surgery. There is a lack of evidence that preoperative physical therapy reduces postoperative pneumothorax, prolonged mechanical ventilation or all-cause deaths.

Abstract
Air leak syndrome includes pulmonary interstitial emphysema, pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, subcutaneous emphysema, and systemic air embolism. The most common cause of air leak syndrome in neonates is inadequate mechanical ventilation of the fragile and immature lungs. The incidence of air leaks in newborns is inversely related to the birth weight of the infants, especially in very-low-birth-weight and meconium-aspirated infants. When the air leak is asymptomatic and the infant is not mechanically ventilated, there is usually no specific treatment. Emergent needle aspiration and/or tube drainage are necessary in managing tension pneumothorax or pneumopericardium with cardiac tamponade. To prevent air leak syndrome, gentle ventilation with low pressure, low tidal volume, low inspiratory time, high rate, and judicious use of positive end expiratory pressure are the keys to caring for mechanically ventilated infants. Both high-frequency oscillatory ventilation (HFOV) and high-frequency jet ventilation (HFJV) can provide adequate gas exchange using extremely low tidal volume and supraphysiologic rate in neonates with acute pulmonary dysfunction, and they are considered to have the potential to reduce the risks of air leak syndrome in neonates. However, there is still no conclusive evidence that HFOV or HFJV can help to reduce new air leaks in published neonatal clinical trials. In conclusion, neonatal air leaks may present as a thoracic emergency requiring emergent intervention. To prevent air leak syndrome, gentle ventilations are key to caring for ventilated infants. There is insufficient evidence showing the role of HFOV and HFJV in the prevention or reduction of new air leaks in newborn infants, so further investigation will be necessary for future applications.

Abstract
OBJECTIVE To determine the efficacy of Computed Tomography (CT)-guided fine needle Aspiration (FNA) in diagnosis of lung masses by trained internists including factors affecting the adequacy of specimens and occurrence rate of complications. MATERIAL AND METHOD 96 patients, aged 25-86 years old underwent CT-guided FNA of thoracic lesions by internists who had been trained for this procedure at the Central Chest Institute of Thailand during March 2007-2008. Demographic data, procedure success and adequacy of specimens for cytological evaluation were summarized including other factors-size and depth of lesion, condition of emphysema and complications of procedure. RESULTS Success of procedure was 97.9%. Adequacy of specimen was 94.7%. Occurrence of pneumothorax was 19 out of 96 cases (19.8%). And 1 case needed to insert inter costal drainage (1.1%). Hemoptysis after procedure was 1.06%. Besides, larger than 3 cm in diameter of lesion presented satisfied specimens more than that of the smaller one. Pneumothorax is the most common complication, which revealed a statistically significant with emphysema around mass. CONCLUSION FNA is an effective and useful tool in diagnosis of pulmonary lesions for trained internists. Success of procedure and adequacy of specimen for cytological evaluation are considerably high and low complications occurred.

Abstract
Placing drains is one the most common procedures following operations in surgical disciplines. The indication for placing a drain is, however, usually based on a traditional belief rather than being evidence-based. This paper presents an overview of the literature regarding the indications and the evidence level for placing drains following operations in visceral, vascular, thoracic and orthopeedic surgery as well as traumatology. In visceral surgery the indications for placing drains could be clarified over the past decades but in other surgical fields the level of evidence needs further investigation and clarification through future studies. The available data suggest that in most cases a prophylactic drainage can be avoided. In addition, drains may lead to increased morbidity and higher treatment costs.

Abstract
This article reviews the possible revival of the supraclavicular brachial plexus blockade due to the use of ultrasound guidance. The brachial plexus is a complex network of nerves, extending from the neck to the axilla, which supplies motor and sensory fibers to the upper extremity. Understanding the complexities of the formation and structure of the brachial plexus remains a cornerstone for effective regional anaesthesia. On the level of the supraclavicular fossa, the plexus is most compactly arranged. The supraclavicular approach of the brachial plexus has a high success rate including blockade of the ulnar and musculocutaneous nerve, which can be missed respectively with the interscalene and axillary approach. However, because of the proximity of the pleura, most anaesthesiologists have been reluctant to perform this supraclavicular approach. The introduction of ultrasound guidance techniques not only reduces the possible risk of pneumothorax but also allows a faster onset time of the block with a reduction of the local anaesthetic dose. This makes the supraclavicular approach a valuable alternative to the axillary, interscalene and infraclavicular approach for upper limb surgery.

Abstract
OBJECTIVES CT-guided transthoracic lung biopsy is widely used in pulmonary lesions diagnosis. This technique rarely entails severe complications such as pneumothorax and pulmonary hemorrhage which call for adequate candidates screening. The aim of our study is to statistically assess risk factors related to these two main complications, and determine the best diagnostic workup. MATERIALS AND METHODS This retrospective study includes 110 patients who underwent CT-guided transthoracic biopsy of a pulmonary lesion. Rates of pneumothorax and pulmonary hemorrhage, as well as their severity, were evaluated, and a correlation with factors related to patients, lesions and biopsy technique were statistically analyzed. RESULTS Higher rates of complications are significantly found with multiple punctures (pneumothorax risk multiplied by 7.4), longer intra-parenchymal needle tract (5 and 7% higher risk of pneumothorax and hemorrhage for every 1 mm increase in depth), and with smaller lesions (2 and 5% lower risk respectively for pneumothorax and hemorrhage for every 1 cm increase in lesion size). The presence of an interposing rib is associated with a higher rate of hemorrhage. CONCLUSION Transthoracic lung biopsy is a minimally invasive technique. However, the presence of associated risk factors must lead to consider another diagnostic method.

Abstract
Pneumothoraces are classified as spontaneous, traumatic and iatrogenic. Spontaneous pneumothoraces that occur without recognized lung disease are termed primary spontaneous pneumothoraces (PSP), whereas those that occur due to an underlying lung disease are termed secondary spontaneous pneumothoraces. The aetiology of secondary, traumatic or iatrogenic pneumothoraces is not usually debated. However, the aetiology of PSP is potentially controversial and often debated. Therefore, PSP is the focus of this article. There are several purported causes, which include blebs, bullae, emphysema-like changes (ELC) and pleural porosity. The controversy is valid because of the importance of recurrence prevention. This article reviews the current available evidence for the causes of PSP. The causes of PSP are likely a combination ELC, pleural porosity and other potential factors.

Abstract
BACKGROUND The practice of pleurodesis for the management and prevention of spontaneous pneumothorax (SP) is uncertain. DESIGN A retrospective multicentre analysis of patients admitted to 12 hospitals in Hong Kong with SP in 2004 and who subsequently underwent pleurodesis for the same episode. RESULTS Pleurodesis was performed in 394 episodes. Initial medical chemical pleurodesis was performed for 258 (65.5%) patients ('initial medical group'), while 136 (34.5%) underwent initial surgical pleurodesis ('initial surgical group'). Secondary spontaneous pneumothorax (SSP; 237 episodes, 60.2%) was the most common indication for pleurodesis; it was also performed after a first episode of primary spontaneous pneumothorax (PSP) in 22 episodes (5.6%). Tetracycline derivatives (172 episodes, 66.7%) were the most popular sclerosing agents in the initial medical group. Those in the initial medical group were older and were more likely to be males, have SSP, chronic obstructive pulmonary disease and a history of past pleurodesis (P < 0.05) compared to the initial surgical group. Compared to the tetracycline group, more patients who initially received talc slurry had the procedure performed by surgeons, had larger (≥2 cm) pneumothorax or required suction during initial drainage (P < 0.05). CONCLUSIONS Despite the availability of international guidelines, there is considerable variation in pleurodesis for SP.
