ABSTRACT
OBJECTIVES: To compare patient-reported outcome measures of minimally invasive (MI) to sternotomy (ST) mitral valve repair. METHODS: We included all patients undergoing isolated mitral valve surgery via either a right mini-thoracotomy (MI) or ST over a 36-month period. Patients were asked to complete a modified Composite Physical Function questionnaire. Intraoperative and postoperative outcomes, and patient-reported outcome measures were compared between 2 propensity-matched groups (n = 47/group), assessing 3 domains: 'Recovery Time', 'Postoperative Pain' (at day 2 and 1, 3, 6 and 12 weeks) and 'Treatment Satisfaction'. Composite scores for each domain were subsequently constructed and multivariable analysis was used to determine whether surgical approach was associated with domain scores. RESULTS: The response rate was 79%. There was no mortality in either group. In the matched groups, operative times were longer in the MI group (P < 0.001), but postoperative outcomes were similar. Composite scores for Recovery Time [ST 51.7 (31.8-62.1) vs MI 61.7 (43.1-73.9), P = 0.03] and Pain [ST 65.7 (40.1-83.1) vs MI 79.1 (65.5-89.5), P = 0.02] significantly favoured the MI group. Scores in the Treatment Satisfaction domain were high for both surgical approaches [ST 100 (82.5-100) vs MI 100 (95.0-100), P = 0.15]. The strongest independent predictor of both faster recovery parameter estimate 12.0 [95% confidence interval (CI) 5.7-18.3, P < 0.001] and less pain parameter estimate 7.6 (95% CI 0.7-14.5, P = 0.03) was MI surgery. CONCLUSIONS: MI surgery was associated with faster recovery and less pain; treatment satisfaction and safety profiles were similar.

BACKGROUND: The association between cerebral desaturation and postoperative delirium in thoracotomy with one-lung ventilation (OLV) has not been specifically studied. METHODS: A prospective observational study performed in thoracic surgical patients. Cerebral tissue oxygen saturation (Scto2) was monitored on the left and right foreheads using a near-infrared spectroscopy oximeter. Baseline Scto2 was measured with patients awake and breathing room air. The minimum Scto2 was the lowest measurement at any time during surgery. Cerebral desaturation and hypersaturation were an episode of Scto2 below and above a given threshold for ≥15 seconds during surgery, respectively. The thresholds based on relative changes by referring to the baseline measurement were <80%, <85%, <90%, <95%, and <100% baseline for desaturation and >105%, >110%, >115%, and >120% baseline for hypersaturation. The thresholds based on absolute values were <50%, <55%, <60%, <65%, and <70% for desaturation and >75%, >80%, >85%, and >90% for hypersaturation. The given area under the threshold (AUT)/area above the threshold (AAT) was analyzed. Delirium was assessed until postoperative day 5. The primary analysis was the association between the minimum Scto2 and delirium using multivariable logistic regression controlled for confounders (age, OLV time, use of midazolam, occurrence of hypotension, and severity of pain). The secondary analysis was the association between cerebral desaturation/hypersaturation and delirium, and between the AUT/AAT and delirium using multivariable logistic regression controlled for the same confounders. Multiple testing was corrected using the Holm-Bonferroni method. We additionally monitored somatic tissue oxygen saturation on the forearm and upper thigh. RESULTS: Delirium occurred in 35 (20%) of 175 patients (65 ± 6 years old). The minimum left or right Scto2 was not associated with delirium. Cerebral desaturation defined by <90% baseline for left Scto2 (odds ratio [OR], 5.82; 95% confidence interval [CI], 2.12-19.2; corrected P =.008) and <85% baseline for right Scto2 (OR, 4.27; 95% CI, 1.77-11.0; corrected P =.01) was associated with an increased risk of delirium. Cerebral desaturation defined by other thresholds, cerebral hypersaturation, the AUT/AAT, and somatic desaturation and hypersaturation were all not associated with delirium. CONCLUSIONS: Cerebral desaturation defined by <90% baseline for left Scto2 and <85% baseline for right Scto2, but not the minimum Scto2, may be associated with an increased risk of postthoracotomy delirium. The validity of these thresholds needs to be tested by randomized controlled trials.

BACKGROUND: Intercostal nerve blocks with liposomal bupivacaine are commonly used for thoracic surgery pain management. However, dose scheduling is difficult because the pharmacokinetics of a single-dose intercostal injection of liposomal bupivacaine has never been investigated. The primary aim of this study was to assess the median time to peak plasma concentration (Tmax) following a surgeon-administered, single-dose infiltration of 266 mg of liposomal bupivacaine as a posterior multilevel intercostal nerve block in patients undergoing posterolateral thoracotomy. METHODS: We chose a sample size of 15 adults for this prospective observational study. Intercostal injection of liposomal bupivacaine was considered time 0. Serum samples were taken at the following times: 5, 15, and 30 minutes, and 1, 2, 4, 8, 12, 24, 48, 72, and 96 hours. The presence of sensory blockade, rescue pain medication, and pain level were recorded after the patient was able to answer questions. RESULTS: Forty patients were screened, and 15 patients were enrolled in the study. Median (interquartile range [IQR]) Tmax was 24 (12) hours (confidence interval [CI], 19.5-28.5 hours) with a range of 15 minutes to 48 hours. The median (IQR) peak plasma concentration (Cmax) was 0.6 (0.3) µg/mL (CI, 00.45-0.74 µg/mL) in a range of 0.3-1.2. The serum bupivacaine concentration was undetectable (<0.2 µg/mL) at 96 hours in all patients. There was significant variability in reported pain scores and rescue opioid medication across the 15 patients. More than 50% of patients had return of normal chest wall sensation at 48 hours. All patients had resolution of nerve blockade at 96 hours. No patients developed local anesthetic toxicity. CONCLUSIONS: This study of the pharmacokinetics of liposomal bupivacaine following multilevel intercostal nerve blockade demonstrates significant variability and delay in systemic absorption of the drug. Peak serum concentration occurred at 48 hours or sooner in all patients. The serum bupivacaine concentration always remained well below the described toxicity threshold (2 µg/mL) during the 96-hour study period.

Our department has a database of thoracic gunshot wounds (GSWs), which has cataloged these injury patterns over the past five decades. Prevailing wisdom on the management of these injuries suggested operative treatment beyond tube thoracostomy is not commonly required. It was our clinical impression that the operative treatment required beyond chest tube placement has greatly increased over the past several decades, whereas the operative management of cardiac GSWs seemed to be increasingly infrequent events. To test these observations, we analyzed the treatment of GSWs to the chest and heart in four distinct time periods, categorized as "historical" (1973-1975 and 1988-1990) and "modern" (2005-2007 and 2015-2017). There was a significant increase in emergent thoracotomy, delayed thoracic operations, overall operative interventions, and pulmonary resections from the historical period to the modern era. There was a decline in cardiac injuries treated, whereas the number of injuries remained constant. Mortality was unchanged between the early and later periods. Operative treatment beyond tube thoracostomy was much more prevalent for noncardiac thoracic GSWs in the past two decades than in the prior decades, whereas the number of cardiac wounds treated decreased by half.

OBJECTIVE: To evaluate the safety and reproducibility of modified right vertical infra axillary thoracotomy (RVIAT) for repair of sinus venosus defects with right-sided partial anomalous pulmonary venous connection (PAPVC) in children. METHODS: Between March 2017 and February 2018, we performed intracardiac repair for sinus venosus defects with right-sided PAPVC in 14 children through modified RVIAT. Median age and weight were 9.5 years and 21 kg, respectively. We modified RVIAT by avoiding central venous cannulation and used total peripheral venous cannulation (right internal jugular vein and right femoral vein). In all children double-patch technique was followed, using untreated autologous pericardium. RESULTS: Intracardiac repair was safely performed in all children. There was no conversion to another approach and there were no complications related to peripheral venous cannulation. All children were in sinus rhythm with no residual defects, with non-obstructive pulmonary venous drainage at the time of discharge and during subsequent follow-ups. CONCLUSIONS: Modified RVIAT can be safely performed for repair of sinus venosus defects with right-sided PAPVC, without compromising on the quality of repair. With this modification not only the intracardiac repair was easier, also it provided more working space with minimal rib spreading.

INTRODUCTION: Surgical data from the National Lung Screening Trial (NLST) has yet to be closely examined. We sought to analyze surgical procedures and complications from the NLST to determine their relevance to modern surgical practice. METHODS: The NLST database was queried for patients who underwent surgical resection for confirmed lung cancer, specifically evaluating postoperative complications. Numerical variables were compared using the Mann-Whitney U test. Categorical variables were compared using the χ2 test. Logistic regression uni- and multivariable analysis of independent risk factors of postoperative complications was performed. RESULTS: At operation, 80% of patients (n = 821) had lobectomy, 4.1% (n = 42) had pneumonectomy, and 16.1% (n = 166) had sublobar resection, among whom 69% (n = 114) had wedge resection. Only 29.6% (n = 305) of the cohort had a thoracoscopic resection. Although the overall rate of surgical patients with any complication was 31% (n = 318), only 15.5% of patients (n = 160) had major complications, most commonly prolonged air leaks (n = 67, 6.5%). Respiratory failure (n = 28, 2.7%), prolonged ventilation (n = 9, 0.9%), myocardial infarction or cardiac arrest (n = 7, 0.7%), and stroke (n = 2, 0.2%) were rare events. Overall 30-day mortality in patients undergoing resection was 1.7% (n = 18). On multivariable analysis, greater smoking pack history (odds ratio [OR], 1.01; 95% confidence interval [CI], 1.001-1.01) and pulmonary comorbidities (OR, 1.34; 95% CI, 0.98-1.82) were significant or approached significance for an association with complications/death, whereas sublobar resection (OR, 0.59; 95% CI, 0.38-0.94) and video-assisted thoracoscopic surgery approach (OR, 0.76; 95% CI, 0.56-1.04) were significant or approached significance for an association with decreased rates of complications/death. CONCLUSIONS: Operative mortality and postoperative morbidity were very low in patients undergoing resection for screen-detected lung cancer. Increased use of sublobar resection and minimally invasive surgical approaches may be associated with fewer complications.

OBJECTIVE: Aortic root enlargement may be necessary to implant adequately sized valves to avoid patient-prosthetic mismatch. Our objective was to assess the feasibility of annular enlargement during aortic valve replacement via a right anterior minithoracotomy. METHODS: Twelve consecutive patients undergoing elective minimally invasive aortic valve replacement requiring annular enlargement over a 2-year period were retrospectively reviewed. A right anterior minithoracotomy was performed in all patients. Cardiopulmonary bypass and aortic crossclamp times, hospital length of stay, postoperative complications, rate of reoperation, echocardiographic data, and mortality were analyzed. RESULTS: Mean age was 66 years ± 14. Mean body mass index was 34 ± 7.8 kg/m2. All patients had normal preoperative ejection fractions. Indications for aortic valve replacement were severe (3/12, 25%) or critical (9/12, 75%) aortic stenosis due to degenerative aortic valve disease (10/12, 83%) and congenitally bicuspid aortic valve (2/12, 17%). Cardiopulmonary bypass and aortic crossclamp times were 144.7 ± 14.7 minutes and 111.7 ± 10.6 minutes, respectively. The median postoperative length of stay was 4 days. Peak and mean aortic valve gradients on postreplacement intraoperative transesophageal echocardiography were 14.5 ± 9.4 mmHg and 7.2 ± 4.2 mmHg, respectively, with no perivalvular leak on intraoperative or follow-up transthoracic echocardiogram. Postoperative transthoracic echocardiography had peak and mean aortic valve gradients of 12.1 ± 6.9 mmHg and 6.3 ± 3.7 mmHg, respectively. There were no postoperative mortalities. Freedom from reoperation was 100%. CONCLUSIONS: Annular enlargement performed during minimally invasive aortic valve replacement is feasible. Basic minimally invasive skills are recommended prior to instituting these more advanced techniques.

BACKGROUND: Therapeutic ultrasound (TU) alleviates nerve injury-associated pain, while the molecular mechanisms are less clear. This is an investigator-initiated experimental study to evaluate the mechanisms and effects of ultrasound on prolonged post-thoracotomy pain in a rodent model. METHODS: The rats were randomly separated into four groups (n=8 per group): sham-operation (sham; group 1), thoracotomy and rib retraction (TRR; group 2), and TRR procedure followed by TU (TRR+TU-3; group 3) or TU with the ultrasound power turned off (TRR+TU-0; group 4). TU was delivered daily, beginning on postoperative day 11 (POD 11) for the next 2 weeks. Mechanical sensitivity, subcutaneous tissue temperature, and spinal substance P and interleukin-1 beta (IL-1ß) were evaluated on PODs 11 and 23. RESULTS: Group 3, which received ultrasound treatment (3 MHz; 1.0 W/cm2) for 5 min each day, demonstrated higher mechanical withdrawal thresholds when compared with the group without ultrasound intervention (group 2) or sham ultrasound (group 4). Ultrasound treatment also inhibited the upregulation of spinal substance P and IL-1ß measured from spinal cord dorsal horns extract and increased subcutaneous temperature. CONCLUSIONS: The results of this study suggest an increase in mechanical withdrawal thresholds and subcutaneous temperature, as well as a downregulation of spinal substance P and IL-1ß, in the group which received ultrasound treatment. The regulation of spinal substance P and IL-1ß may mediate potential effects of this non-invasive treatment.

Between 2000 and 2008, the mitral valve (MV) repair rate in patients with severe mitral regurgitation at our low-volume Veterans Affairs hospital was 21%. After instituting a multidisciplinary valve team in 2009, we determined whether this rate increased and characterized the outcomes of patients with degenerative disease. We retrospectively reviewed data from 103 MV operations performed at our hospital between 1/2009 and 8/2016. MV pathology was categorized as degenerative, rheumatic, endocarditis, ischemic, hypertrophic cardiomyopathy, or failed prior MV repair. The surgical techniques used for MV repair were reviewed. For the patients with degenerative disease who underwent MV repair, we assessed leaflet involvement and postoperative valve function. For the full cohort, the MV repair rate was 67% and the 30-day mortality rate was 0.97%. Of the 74 patients with degenerative disease, 64 (86.5%) underwent MV repair (none required reoperation). For these patients, the MV repair rate was significantly higher when the surgical approach was sternotomy rather than minimally invasive right minithoracotomy (92.5% vs 71.4%, Pâ¯=â¯0.03). After MV repair, 95.3% of the degenerative disease patients had mild or less mitral regurgitation; median echocardiography follow-up time was 555 days. Anatomic features associated with a reduced MV repair rate in patients with degenerative disease were dystrophic leaflet calcification and severe mitral annular calcification. In an institution with a low volume of MV operations, preoperative surgical planning with a multidisciplinary valve team was associated with improved MV repair rates and excellent repair quality in patients with degenerative valve disease.

BACKGROUND: Until now, the traditional procedure to treat intralobar pulmonary sequestration (ILS) in adults has been a lobectomy performed by open thoracotomy. We have reviewed our data to observe if the surgical management of these lesions has evolved over the last years. METHODS: We retrospectively reviewed the records of the patients who were operated for an ILS either by posterolateral thoracotomy (PLT group), or by thoracoscopy (TS group) between 2000 and 2016. RESULTS: Eighteen patients were operated for a SIL during this period. Prior to 2011, all resections were performed by thoracotomy (n=6) and after 2011 the surgical approach was either a thoracotomy (n=5) or a thoracoscopy (n=7). There was one conversion because of dense pleural adhesions and this patient was integrated in the PLT group for further analysis. ILS were more frequently encountered on the left side (n=12, 66.6 %) than on the right one (n=6, 33.3 %) and exclusively in the lower lobes. All patients of the PLT group underwent a lobectomy. In the TS group, 5 patients underwent a sublobar resection (2 segmentectomiesS9+10, 1 basilar segmentectomy and 2 atypical resections). There was no mortality. In the PLT group, 5 patients (45 %) had complications versus one patient (14 %) in the TS group. The mean hospital stay was 7.4 days in the PLT group versus 5.4 days in the TS group. CONCLUSIONS: These data confirm that ILS can be safely treated by a sublobar resection that should be performed, whenever possible, thoracoscopically.

OBJECTIVES: To investigate the relationships between secondhand smoke (SHS) exposure and oxygenation during one-lung ventilation (OLV) in lobectomy surgery and between SHS exposure and postoperative analgesic consumption. DESIGN: Prospective study. SETTING: University, Faculty of Medicine, operating room. PARTICIPANTS: Sixty adult patients with American Society of Anesthesiologists score II to III, aged 18 to 65 years, with a body mass index (BMI) <35 kg/m2 scheduled for lobectomy surgery by open thoracotomy. INTERVENTIONS: Patients were divided into 2 groups: the SHS group (nâ¯=â¯30) (urine cotinine level ≥6.0 ng/mL) and the NS (nonsmoker) group (nâ¯=â¯30) (urine cotinine level <6.0 ng/mL and no smoking history). SHS exposure was defined according to a previously published algorithm. MEASUREMENTS AND MAIN RESULTS: Noninvasive blood pressure, electrocardiography, capnography, and peripheral oxygen saturation were monitored, and intra- and postoperative arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), and intraoperative peak airway pressure were compared between the 2 groups. Postoperative analgesic consumption was calculated. No significant differences in demographics or preoperative data were noted between the 2 groups. PaO2 values 10 minutes after OLV onset and 10 minutes after the end of OLV were increased significantly in the NS group compared with those in the SHS group (p < 0.05). PaO2 values after 10 minutes of OLV in the NS and SHS groups were 285.5 ± 90 mmHg and 186.7 ± 66 mmHg, respectively. PaO2 values after OLV termination in the NS and SHS groups were 365.8 ± 58 mmHg and 283.6 ± 64 mmHg (p < 0.05), respectively. PaCO2 values 10 minutes after OLV onset, 10 minutes after the end of OLV, at the end of surgery, and upon arrival in the intermediate care unit were significantly different between the 2 groups (p < 0.05). CONCLUSION: The present study demonstrated that during OLV, patients exposed to SHS exhibited significantly lower arterial oxygen pressure compared with nonsmokers. Arterial carbon dioxide values were increased significantly in SHS-exposed patients. Morphine consumption for postoperative analgesia also was increased in patients exposed to SHS compared with that in nonsmokers.

BACKGROUND: The analgesic effects of dexamethasone have been reported previously, and the present study determined the effects of preoperative dexamethasone on postoperative pain in patients who received thoracotomy. METHODS: Forty patients participated in this randomized, double-blind study. All patients received either dexamethasone via a 0.1 mg/kg intravenous bolus before anesthetic induction or an equal volume of saline. Postoperative analgesia was provided to both groups via epidural patient-controlled analgesia (PCA), which consisted of 250 µg of sufentanil in 250 mL of ropivacaine (0.18%) for 72 h. The primary outcome was the cumulative consumption of epidural PCA at postoperative 24 and 72 h. The secondary outcomes were the pain intensity scores during resting and coughing at postoperative 24 and 72 h, quality of recovery, total amount of rescue analgesics required, and length of hospital stay. RESULTS: No significant differences was observed in the consumption of epidural PCA between the control and dexamethasone infusion groups at 24 h (63.6 [55.9-72.7] vs. 68.5 [60.2-89.0] ml, P = 0.281) and 72 h (199.4 [172.4-225.1] vs. 194.7 [169.1-252.2] ml, P = 0.890). Moreover, there was no significant difference in the pain intensity scores during resting and coughing at postoperative 24 and 72 h, quality of recovery, total amount of rescue analgesics required, and length of hospital stay. CONCLUSION: A single intravenous administration of dexamethasone during the preoperative period does not reduce opioid consumption and post-thoracotomy pain. TRIAL REGISTRATION: The study was registered at http://cris.nih.go.kr ( KCT0000359 ) and was conducted from December 2011 to October 2012.

Resuscitative thoracotomy has been extensively described in the civilian trauma literature and has a high mortality rate, due largely to the nature of the injuries leading to arrest. The survival rates are generally highest (10-30%) for penetrating truncal injuries and patients who arrive with vital signs and proceed to arrest or who have impending arrest. They are significantly lower (less than 5%) for blunt trauma victims, particularly those who arrest in the field or during transport (1% or less). In addition, the likelihood of survival with intact neurologic function is significantly lower than the overall survival rates, particularly for blunt trauma victims and for prehospital arrest.

Background Pediatric chest injuries were infrequent in our practice, but the outbreak of the Syrian crisis resulted in an increase in number and a change in the pattern of thoracic trauma incidents. We compared our experience of pediatric chest injuries before and during the crisis. Methods We reviewed the records of 256 children aged 12.8 ± 5 years who were admitted to our hospital with the diagnosis of chest trauma over a 12-year period. Collected data included mechanism of injury, associated injuries, method of management, length of hospital stay, complications, and mortality. Results The incidence of pediatric chest injuries increased significantly following the outbreak of the crisis, and penetrating injuries prevailed, mainly due to shrapnel, bullets, and stab wounds. Forty percent of patients with blunt injuries and 20% of those with penetrating injuries were managed conservatively, whereas urgent thoracotomies were indicated in 10%, mostly in patients with penetrating injuries. Associated injuries were more frequent in patients with blunt injuries and resulted in a longer hospital stay and an increased mortality rate. The overall mortality rate was 7.8% and it was higher in children younger than 7 years of age and in patients who had been subjected to blunt injuries. Conclusions There has been a recent substantial upsurge in the incidence of pediatric thoracic trauma, with a predominance of penetrating injuries. Most patients could be managed nonoperatively, but a small subset required an open thoracotomy. The presence of associated injuries constitutes the main determinant of prognosis in this group of patients.

OBJECTIVES: To evaluate the efficacy of ultrasound-guided interscalene nerve block using an ultralow volume of local anesthetic (5 mL of ropivacaine, 0.75%) for the management of post-thoracotomy shoulder girdle pain. DESIGN: Open-cohort, prospective, single-center study. SETTING: University hospital. INTERVENTIONS: Patients with post-thoracotomy shoulder girdle pain (visual analog scale [VAS] ≥5) received an ultrasound-guided interscalene nerve block. MEASUREMENTS AND MAIN RESULTS: Thirty minutes after block implementation, the VAS was used to quantify pain across the shoulder girdle. The index (I) was calculated to indicate improvement of pain as follows: [Formula: see text] Nerve bocks resulting in I ≥75% were considered excellent. Total tramadol consumption 36 hours after nerve blocks, patients' satisfaction, and complications related to the procedure also were assessed. Patients were segregated in the following 2 groups: group A, which comprised patients with pain in the shoulder area (glenohumeral and acromioclavicular joints) (n = 30), and group B, which comprised patients with pain in the scapula (n = 17). I was significantly greater in group A (88.3% ± 14%) than in group B (43.2% ± 22%). In groups A and B, 90% and 11% of patients, respectively, demonstrated excellent pain control. Total tramadol consumption in group A, 25 (0-100) mg, was significantly less that of group B, 250 (150-500) mg. Patients' satisfaction also was significantly higher in group A compared with group B. No complications were recorded. CONCLUSIONS: Ultrasound-guided interscalene nerve block can substantially alleviate post-thoracotomy pain in the shoulder but not in the scapular area.
