Cardiogenic Unilateral Pulmonary Edema: An Unreported Complication of a Digestive Endoscopic Procedure

CONGESTIVE HEART FAILURE, Issue 5 2009
Enrique M. Baldessari MD
Unilateral pulmonary edema is an uncommon clinical situation that may be difficult to distinguish from other conditions that cause lung infiltrates. Most cases occur in the right lung, and there are no reports about cardiogenic unilateral pulmonary edema as a complication of an endoscopic procedure of gastrointestinal tract. The authors describe a case of a 79-year-old woman with acute cardiac heart failure that developed soon after a diagnostic upper and lower digestive endoscopy. Continuous positive airway pressure, intravenous nitroglycerin, and furosemide treatment resulted in rapid improvement of symptoms and the progressive resolution of left-sided infiltrates on chest radiography. This case is of particular importance because of the rarity of cardiogenic unilateral edema in the left lung. This clinical finding was associated with the prolonged rest on the left side during the gastrointestinal endoscopic procedure. [source]


Alcohol Abuse Enhances Pulmonary Edema in Acute Respiratory Distress Syndrome

ALCOHOLISM, Issue 10 2009
David M. Berkowitz
Background:, Pulmonary edema is a cardinal feature of the life-threatening condition known as acute respiratory distress syndrome (ARDS). Patients with chronic alcohol abuse are known to be at increased risk of developing and dying from ARDS. Based upon preclinical data, we hypothesized that a history of chronic alcohol abuse in ARDS patients is associated with greater quantities and slower resolution of pulmonary edema compared with ARDS patients without a history of alcohol abuse. Methods:, A PiCCOÔ transpulmonary thermodilution catheter was inserted into 35 patients within 72 hours of meeting American European Consensus Criteria definition of ARDS. Pulmonary edema was quantified as extravascular lung water (EVLW) and measured for up to 7 days in 13 patients with a history of chronic alcohol abuse and 22 patients without a history of chronic alcohol abuse. Results:, Mean EVLW was higher in patients with a history of chronic alcohol abuse (16.6 vs. 10.5 ml/kg, p < 0.0001). Patients with alcohol abuse had significantly greater EVLW over the duration of the study (RM-ANOVA p = 0.003). There was a trend towards slower resolution of EVLW in patients with a history of alcohol abuse (a decrease of 0.5 ml/kg vs. 2.4 ml/kg, p = 0.17) over the study period. A history of alcohol abuse conferred a greater than 3-fold increased risk of elevated EVLW [OR 3.16, (1.26 to 7.93)] using multivariate logistic regression analysis. Conclusions:, In patients who develop ARDS, alcohol abuse is associated with greater levels EVLW and a trend towards slower resolution of EVLW. Combined with mechanistic and preclinical evidence linking chronic alcohol consumption and ARDS, targeted therapies should be developed for these patients. [source]


Pulmonary edema in the transurethral resection syndrome induced with mannitol 5%

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2009
J. H. WANG
Two patients developed the transurethral resection (TUR) syndrome after having absorbed mannitol 5% during TUR of the prostate. Both developed pulmonary edema and became severely hypoatremic (lowest serum sodium 99 and 97 mmol/l, respectively). Hypertonic saline was infused to raise the serum sodium level and plasma volume expansion used to combat hypotension. One patient also required positive-pressure ventilation and intravenous administration of norepinephrine. Both patients recovered completely [source]

Oxford experience with neoadjuvant chemotherapy and surgical resection for esophageal adenocarcinomas and squamous cell tumors

DISEASES OF THE ESOPHAGUS, Issue 3 2008
P. M. Safranek
SUMMARY., The Medical Research Council trial for oesophageal cancer (OEO2) trial demonstrated a clear survival benefit from neoadjuvant chemotherapy in resectable esophageal carcinoma. Since February 2000 it has been our practice to offer this chemotherapy regime to patients with T2 and T3 or T1N1 tumors. We analyzed prospectively collected data of patients who received neoadjuvant chemotherapy prior to esophageal resection under the care of a single surgeon. Complications of treatment and overall outcomes were evaluated. A total of 194 patients had cisplatin and 5-fluorouracil prior to esophageal resection. Six patients (5.7%) had progressive disease and were inoperable (discovered in four at surgery). During chemotherapy one patient died and one perforated (operated immediately). Complications including severe neutropenia, coronary artery spasm, renal impairment and pulmonary edema led to the premature cessation of chemotherapy in 12 patients (6.2%). A total of 182 patients with a median age of 63 (range 30,80), 41 squamous and 141 adenocarcinomas underwent surgery. Operations were 91 left thoracoabdominal (50%), 45 radical transhiatal (25%), 40 Ivor-Lewis (22%) and six stage three (3%), and 78.6% had microscopically complete (R0) resections. Median survival was 28 months with 77.3% surviving for 1 year and 57.7% for 2 year. In hospital mortality was 5.5% and anastomotic leak rate 7.7%. A radical surgical approach to the primary tumor in combination with OEO2 neoadjuvant chemotherapy has led to a high R0 resection rate and good survival with acceptable morbidity and mortality.

Prosthetic Valve Dysfunction Presenting as Intermittent Acute Aortic Regurgitation

ECHOCARDIOGRAPHY, Issue 8 2008
Dali Fan M.D., Ph.D.
We describe the case of a 43 year old man with a history of aortic stenosis, for which he had undergone aortic valve replacement in 1991 with a 25-mm Medtronic Hall prosthesis. He presented with several acute episodes of dyspnea and flash pulmonary edema. Transthoracic and transesophageal echocardiography performed to evaluate prosthetic valve function revealed evidence of "intermittent" episodes of AI, documented on color M-mode flow mapping to have a variable duration of diastolic flow (early vs. pandiastolic) across the left ventricular outflow tract and the pulse wave Doppler in the descending thoracic aorta showed similar variability in the duration of diastolic flow reversal.

Accuracy of Tissue Doppler Echocardiography in the Diagnosis of New-Onset Congestive Heart Failure in Patients with Levels of B-Type Natriuretic Peptide in the Midrange and Normal Left Ventricular Ejection Fraction

ECHOCARDIOGRAPHY, Issue 8 2006
Stephane Arques M.D.
Background: Based on the hypothesis that it reflects left ventricular (LV) diastolic pressures, B-type natriuretic peptide (BNP) is largely utilized as first-line diagnostic complement in the emergency diagnosis of congestive heart failure (HF). The incremental diagnostic value of tissue Doppler echocardiography, a reliable noninvasive estimate of LV filling pressures, has been reported in patients with preserved LV ejection fraction and discrepancy between BNP levels and the clinical judgment, however, its clinical validity in such patients in the presence of BNP concentrations in the midrange, which may reflect intermediate, nondiagnostic levels of LV filling pressures, is unknown. Methods: 34 patients without history of HF, presenting with acute dyspnea at rest, BNP levels of 100,400 pg/ml and normal LV ejection fraction were prospectively enrolled (17 with congestive HF and 17 with noncardiac cause). Tissue Doppler echocardiography was performed within 3 hours after admission. Results: unlike BNP (P = 0.78), Boston criteria (P = 0.0129), radiographic pulmonary edema (P = 0.0036) and average E/Ea ratio (P = 0.0032) were predictive of congestive HF by logistic regression analysis. In this clinical setting, radiographic pulmonary edema had a positive predictive value of 80% in the diagnosis of congestive HF. In patients without evidence of radiographic pulmonary edema, average E/Ea > 10 was a powerful predictor of congestive HF (area under the ROC curve of 0.886, P < 0.001, sensitivity 100% and specificity 78.6%). Conclusion: by better reflecting LV filling pressures, bedside tissue Doppler echocardiography accurately differentiates congestive HF from noncardiac cause in dyspneic patients with intermediate, nondiagnostic BNP levels and normal LV ejection fraction.

Postictal Central Apnea as a Cause of SUDEP: Evidence From Near-SUDEP Incident

EPILEPSIA, Issue 11 2000
Elson L. So
Summary: While undergoing video-EEG monitoring, a 20-year-old woman had a 56-second convulsive seizure, after which she developed persistent apnea. The rhythm of the electrocardiogram complexes was unimpaired for approximately 10 seconds, after which it gradually and progressively slowed until it stopped 57 seconds later. Evaluation after successful cardiorespiratory resuscitation showed no evidence of airway obstruction or pulmonary edema. The patient had a previous cardio-respiratory arrest after a complex partial seizure without secondary generalization. Although epileptic seizures are known to be potentially arrhythmogenic to the heart, our observations strongly suggest that one probable mechanism of sudden unexplained death in epilepsy is the marked central suppression of respiratory activity after seizures.

A case report of systemic capillary leak syndrome (Clarkson's disease)

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010
J. HOLLENBERG
Systemic capillary leak syndrome (SCLS) is a very rare disorder also known as Clarkson's disease. The condition is characterized by recurrent episodes of severe capillary hyperpermeability resulting in severe hemoconcentration, hypoalbuminemia, hypovolemia and shock. We describe a 41-year-old previously healthy man who was admitted to hospital on several occasions with rapidly developing hypovolemic shock accompanied by extreme hemoconcentration and hypoalbuminemia. Our case is similar to other reports describing patients with SCLS where the initial suspicions have been pointing towards septic shock. He received a combination of prophylactic treatment with theophylline, ,-agonists, immunoglobulins and statins but eventually died after a severe episode of SCLS that ended with recurrent cardiac arrest. Clinical autopsy revealed pulmonary edema and acute and chronical organic fluid overload. SCLS should be kept in mind when treating patients suffering from attacks of severe idiopathic edema and mimics recurrent septic shock where no pathogen is found. The pathogenesis is unknown and the attacks may be lethal. [source]


Mitral Valve Replacements in Redo Patients with Previous Mitral Valve Procedures: Mid-Term Results and Risk Factors for Survival

JOURNAL OF CARDIAC SURGERY, Issue 5 2008
Tankut Hakki Akay M.D.
Patients and Methods: Between September 1989 and December 2003, 62 redo patients have undergone mitral valve replacements due to subsequent mitral valve problems. Preoperative, operative, and postoperative data were analyzed retrospectively and evaluated for risk factors affecting hospital mortality, mid- and long-term survival. Results: The hospital mortality was 6.4%. The one-, five-, and 10-year actuarial survival rates were 94%± 2%, 89%± 6%, and 81 ± 9%. New York Heart Association (NYHA) functional class IV, low left ventricular ejection fraction (<35%), increased left ventricular end-diastolic diameter (LVEDD) > 50 mm, female gender, pulmonary edema, and urgent operations were found to be risk factors in short-term survival. NYHA functional class IV, low left ventricular ejection fraction, increased LVEDD, and increased left atrial diameter (LA > 60 mm) were risk factors in mid-term survival. Conclusion: Redo mitral valve surgery with mechanical prosthesis offers encouraging short- and mid-term survival. NYHA functional class IV, low left ventricular ejection fraction, and increased left ventricular diameters were especially associated with increased short- and mid-term mortality. Earlier surgical management before the development of severe heart failure and myocardial dysfunction would improve the results of redo mitral valve surgery. [source]

Alcohol Abuse Enhances Pulmonary Edema in Acute Respiratory Distress Syndrome

ALCOHOLISM, Issue 10 2009
David M. Berkowitz
Background:, Pulmonary edema is a cardinal feature of the life-threatening condition known as acute respiratory distress syndrome (ARDS). Patients with chronic alcohol abuse are known to be at increased risk of developing and dying from ARDS. Based upon preclinical data, we hypothesized that a history of chronic alcohol abuse in ARDS patients is associated with greater quantities and slower resolution of pulmonary edema compared with ARDS patients without a history of alcohol abuse. Methods:, A PiCCOÔ transpulmonary thermodilution catheter was inserted into 35 patients within 72 hours of meeting American European Consensus Criteria definition of ARDS. Pulmonary edema was quantified as extravascular lung water (EVLW) and measured for up to 7 days in 13 patients with a history of chronic alcohol abuse and 22 patients without a history of chronic alcohol abuse. Results:, Mean EVLW was higher in patients with a history of chronic alcohol abuse (16.6 vs. 10.5 ml/kg, p < 0.0001). Patients with alcohol abuse had significantly greater EVLW over the duration of the study (RM-ANOVA p = 0.003). There was a trend towards slower resolution of EVLW in patients with a history of alcohol abuse (a decrease of 0.5 ml/kg vs. 2.4 ml/kg, p = 0.17) over the study period. A history of alcohol abuse conferred a greater than 3-fold increased risk of elevated EVLW [OR 3.16, (1.26 to 7.93)] using multivariate logistic regression analysis. Conclusions:, In patients who develop ARDS, alcohol abuse is associated with greater levels EVLW and a trend towards slower resolution of EVLW. Combined with mechanistic and preclinical evidence linking chronic alcohol consumption and ARDS, targeted therapies should be developed for these patients. [source]


Segmental lung lobe torsion in a 7-week-old Pug

JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 3 2006
MACVSc, Naomi L. Hansen BVSc
Abstract Case summary: A 7-week-old, intact female Pug was referred with an acute history of expiratory dyspnea, tachypnea, and pyrexia. Radiologic evaluation revealed bilateral pleural effusion and a poorly demarcated area of soft tissue opacity cranial to the heart. The presence of air bronchograms in the cranial lung lobes suggested alveolar parenchymal pathology consistent with pulmonary edema, congestion, or cellular infiltration. Exploratory thoracotomy revealed a segmental torsion of the left cranial lung lobe. The affected lobe was removed and the puppy recovered uneventfully. Unique information: Lung lobe torsion tends to occur more frequently in mature large breed dogs at a mean age of 3 years. The age, breed, and segmental nature of the torsion in the reported case are contrary to most of the previously documented cases of lung lobe torsion. To the authors' knowledge, this is the first report of lung lobe torsion in a 7-week-old dog. [source]


Phase I Clinical Evaluation of Carboplatin in Tumor-Bearing Cats: A Veterinary Cooperative Oncology Group Study

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 1 2008
W.C. Kisseberth
Background: The dosage of carboplatin in cats has been reported anecdotally and experimentally in non-tumor-bearing cats, but the dosage for carboplatin treatment in tumor-bearing cats has yet to be defined in a prospective clinical trial. Purpose: To determine the maximally tolerated dose (MTD) and dose-limiting toxicosis (DLT) of carboplatin in tumor-bearing cats. Cats: Fifty-nine cats with measurable solid tumors. Methods: The starting dose of carboplatin was 160 mg/m2 of body surface area IV. Doses were increased by 20 mg/m2 in cohorts of 3,14 cats until the MTD was reached. Results: The 59 cats entered into this multi-institutional phase I study received 1 or more doses of carboplatin at various dosages and were evaluated for toxicity, response to treatment, or both. The MTD was 240 mg/m2 and neutropenia was the DLT. For the 1st cycle of treatment in 44 cats evaluated for neutropenia, 6 episodes of grade 3 or greater neutropenia occurred on days 7 (n=1), 14 (n=4), and 21 (n=1). There was no evidence of drug-induced nephrotoxicosis or pulmonary edema. Preliminary evidence of antitumor activity was observed in 7 of 59 (11.9%; 95% CI, 5.6,22.8%) cats evaluated for response to treatment. There was 1 complete response (cutaneous hemangiosarcoma) and 6 partial responses (4 injection site sarcomas, 1 oral squamous cell carcinoma, 1 lymphoma). Responses were of short duration (median, 42 days; range, 7,168 days). Conclusions and Clinical Importance: The dose of carboplatin recommended to treat tumor-bearing cats is 240 mg/m2 IV every 3,4 weeks. [source]

Fluid challenge in patients at risk for fluid loading-induced pulmonary edema

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2004
M. Matejovic
Background:, This study evaluated the effects of protocol-guided fluid loading on extravascular lung water (EVLW) and hemodynamics in a group of patients at high risk for volume expansion-induced pulmonary and systemic edema. Methods:, Nine acutely admitted septic patients with acute lung injury (ALI) were prospectively studied. In addition to sepsis and ALI, the following criteria indicating increased risk for edema formation had to be fulfilled: increased vascular permeability defined as microalbuminuria greater than fivefold normal and hypoalbuminemia <30 g l,1. Two hundred-ml boluses of a 10% hydroxyethyl starch (HES) was titrated to obtain best filling pressure/stroke volume relation. Extravascular lung water and intrathoracic blood volume (ITBV) were measured using a transpulmonary double-indicator dilution technique. Baseline data were compared with data at the end of fluid loading and 3 h postchallenge. Results:, At study entry the mean EVLW was 13 ml kg,1, and the mean EVLW/ITBV ratio (indicator of pulmonary permeability) was 0.72 (normal range 0.20,0.30). To attain optimal preload/stroke volume relation 633 ± 240 ml of HES was needed. Fluid loading significantly increased preload (CVP, PAOP and ITBV), and stroke volume. Effective pulmonary capillary pressure (Pcap) rose only slightly. As a result, the Pcap,PAOP gradient decreased. Despite increased cardiac output, EVLW did not change by plasma expansion. Conclusion:, In this selected group of at-risk patients, the optimization of cardiac output guided by the concept of best individual filling pressure/stroke volume relationship did not worsen permeability pulmonary edema.

Bilateral pulmonary edema after endoscopic sympathectomy in a patient with glucose-6-phosphate dehydrogenase deficiency

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2001
C.-J. Lan
Transaxillary endoscopic sympathectomy of thoracic ganglia (T2,T3) has recently gained wider acceptance as the treatment of choice for palmar hyperhidrosis. It requires one-lung ventilation to facilitate the surgery. One-lung ventilation, however, is not without complications, among which acute pulmonary edema has been reported. In this case report, we present a patient with palmar hyperhidrosis complicated by glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, who received bilateral endoscopic sympathectomy under alternate one-lung anesthesia, and developed acute pulmonary edema immediately after recruitment of the successive collapsed lung. The effects of hypoxemia, G-6-PD deficiency and sympathectomy might all add to the development of acute pulmonary edema secondary to reexpansion of each individual lung after alternate one-lung ventilation. The possibilities of the inferred causes are herein discussed. [source]

Biventricular Pacing for Severe Mitral Reguritation Following Atrioventrgicular Nodal Ablation

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 2p1 2003
PATRICK J.S. DISNEY
DISNEY, P.J.S., et al.: Biventricular Pacing for Severe Mitral Regurgitation Following Atrioventricular Nodal Ablation. A 69-year-old woman developed acute pulmonary edema and severe mitral regurgitation (MR) 2 days following an uncomplicated AV nodal (AVN) ablation and insertion of VVI pacemaker for chronic atrial fibrillation. There was no history of significant mitral valve disease. Left ventricular function was normal and there was no evidence of an acute cardiac ischemic event. Transthoracic echo and right heart catheterization studies showed reduction in the severity of MR with biventricular pacing as opposed to RV pacing alone. A permanent pacemaker configured for biventricular pacing was implanted with complete resolution of symptoms and significant reduction in degree of MR. (PACE 2003; 26[Pt. I]:643,644) [source]


Electrophysiologist-Implanted Transvenous Cardioverter Defibrillators Using Local Versus General Anesthesia

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 1 2000
ANTONIS S. MANOLIS
With the advent of smaller biphasic transvenous implantable Cardioverter defibrillators (ICDs) and the experience gained over the years, it is now feasible for electrophysioiogists to implant them safely in the abdominal or pectoral area without surgical assistance. Throughout the years, general anesthesia has been used as the standard technique of anesthesia for these procedures. However, use of local anesthesia combined with deep sedation only for defibrillation threshold (DFT) testing might further facilitate and simplify these procedures. The purpose of this study was to test the feasibility of using local anesthesia and compare it with the standard technique of general anesthesia, during implantation of transvenous ICDs performed by an electrophysiologist in the electrophysiology laboratory. For over 4 years in the electrophysiology laboratory, we have implanted transvenous ICDs in 90 consecutive patients (84 men and 6 women, aged 58 ± 15 years). Early on, general anesthesia was used (n = 40, group I), but in recent series (n = 50, group II) local anesthesia was combined with deep sedation for DFT testing. Patients had coronary (n = 58) or valvular (n = 4) disease, cardiomyopathy (n = 25) or no organic disease (n = 3), a mean left ventricular ejection fraction of 35%, and presented with ventricular tachycardia (n = 72) or fibrillation (n = 16), or syncope (n = 2). One-lead ICD systems were used in 74 patients, two-lead systems in 10 patients, andan AVICD in 6 patients. ICDs were implanted in abdominal (n = 17, all in group I) or more recently in pectoral (n = 73) pockets. The DFT averaged 9.7 ± 3.6 J and 10.2 ± 3.6 J in the two groups, respectively (P = NS) and there were no differences in pace-sense thresholds. The total procedural duration was shorter (2.1 ± 0.5 hours) in group II (all pectoral implants) compared with 23 pectoral implants of group I (2.9 ± 0.5 hours) (P < 0.0001). Biphasic devices were used in all patients and active shell devices in 67 patients; no patient needed a subcutaneous patch. There were six complications (7%), four in group I and two in group II: one pulmonary edema and one respiratory insufficiency that delayed extubation for 3 hours in a patient with prior lung resection, both probably related to general anesthesia, one lead insulation break that required reoperation on day 3, two pocket hematomas, and one pneumothorax. There was one postoperative arrhythmic death at 48 hours in group I. No infections occurred. Patients were discharged at a mean time of 3 days. All devices functioned well at predischarge testing. Thus, it is feasible to use local anesthesia for current ICD implants to expedite the procedure and avoid general anesthesia related cost and possible complications. [source]

Non-cardiogenic pulmonary edema during basiliximab induction in three adolescent renal transplant patients

PEDIATRIC TRANSPLANTATION, Issue 4 2003
Fatai O. Bamgbola
Abstract:, Background:, Introduction of the anti-CD-25 mAb basiliximab into renal transplant protocols has reduced the incidence of acute rejection. However, its side-effect profile is still unfolding. We report three adolescents who developed severe non-cardiogenic PE within 2 days of renal transplantation. Methods:, Pretransplant cardiorespiratory evaluation was normal in all cases. Transplant immunosuppression consisted of basiliximab induction, corticosteroids, and tacrolimus. Patients received standard fluid management during and after the transplant surgery. Case reports:, Patients 1 and 2 were 17- and 21-yr-old females. Pretransplant Hct values were 35 and 25% respectively. Each received 5-L normal saline during surgery. EBL was 200 and 500 mL in patients 1 and 2, respectively. There was immediate post-operative diuresis. Both developed non-cardiogenic PE by POD no. 2. BIPAP and PRVC were administered respectively. In both cases PE resolved within 1 wk. Patient 3 was a 19-yr-old male with pretransplant Hct of 43% who received a cadaveric renal transplant after 23.5-h cold-ischemia; 3.5 L normal saline was given during surgery. EBL was 100 mL. Non-cardiogenic PE ensued on POD no. 2 warranting assisted ventilation. The patient died following a sudden cardiopulmonary arrest on POD no. 3. Conclusions:, Potential mechanisms for the development of PE include cytokine release from basiliximab with increased capillary permeability, volume overload and ischemic-reperfusion injury. Improved awareness of this potential complication, prudent fluid management, and efforts to minimize graft-ischemia are recommended to prevent further cases. [source]


Hemodialysis patient beliefs by stage of fluid adherence

RESEARCH IN NURSING & HEALTH, Issue 2 2001
Janet L. Welch
Abstract Fluid limitations are difficult for hemodialysis patients to follow, and factors related to fluid adherence are not well known. The primary purpose of this study, which was guided by the health belief model and the transtheoretical model for behavior change, was to determine whether differences exist in perceived benefits, barriers, susceptibility, seriousness, or self-efficacy among individuals in different stages of fluid adherence. In a cross-sectional descriptive design, 148 persons (mean age=53.9 years; 52% male) were interviewed using a structured format. Hemodialysis patients in the action/maintenance stage perceived significantly more benefits to fluid adherence than persons in the precontemplation stage. Persons who were in the action/maintenance stage perceived they were significantly more susceptible to pulmonary edema than persons in the contemplation stage. Stage-appropriate interventions may be needed to target specific beliefsabout fluid adherence. © 2001 John Wiley & Sons, Inc. Res Nurs Health 24: 105,112, 2001 [source]


Role of Protease Activated Receptor 2 in Experimental Acute Lung Injury and Lung Fibrosis

THE ANATOMICAL RECORD : ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Issue 4 2009
Xiao Su
Abstract Protease activated receptor 2 (PAR2) is widely-distributed (lung, liver, kidney, etc.) and expressed by variety of cells (i.e. leukocytes, epithelial cells, endothelial cells, and fibroblast). PAR2 may participate in many pathological processes, such as, inflammation, injury, as well as fibrosis. Therefore, in this study, we tested whether PAR2 would exert a role in acid-induced acute lung injury, E. coli pneumonia, bleomycin-induced acute lung injury and fibrosis. Acid, E. coli, or bleomycin were intratracheally instilled into the lungs of both wildtype and PAR2 knockout mice to detect differences in pulmonary edema, lung vascular permeability, lung fibrosis, and other parameters. Knockout of PAR2 did not affect the extent of pulmonary edema and lung vascular permeability in acid-induced acute lung injury. Also, both activation of PAR2 in the airspaces of the lung and deletion of PAR2 did not alter the magnitude of pulmonary edema and lung vascular permeability in E. coli pneumonia. Finally, PAR2 deficiency did not affect the severity of lung inflammation and lung fibrosis in bleomycin-induced acute lung injury and lung fibrosis models. Thus, PAR2 does not appear to play a critical role in the pathogeneses of experimental acid-induced acute lung injury, E. coli pneumonia, and bleomycin-induced acute lung injury and pulmonary fibrosis in mice.

Postobstructive Pulmonary Edema After Laryngospasm in the Otolaryngology Patient

THE LARYNGOSCOPE, Issue 9 2006
Vishvesh M. Mehta MD
Abstract Context: Post-obstructive pulmonary edema (PPE) is an uncommon complication which develops immediately after the onset of acute airway obstruction such as laryngospasm or epiglottitis (type I) or after the relief of chronic upper airway obstruction such as adenotonsillar hypertrophy (type II). Objective: To describe the development of type I PPE following laryngospasm in pediatric and adult patients undergoing otolaryngologic surgical procedures other than those for treatment of obstructive sleep apnea. Design: Retrospective case series of 13 otolaryngology patients from 1996 to 2003. Setting: Tertiary care teaching hospital and its affiliates. Patients: 13 patients (4 children, 9 adults, 5 males, 8 females) ranging in age from 9 months to 48 years. Results: Operative procedures included adenoidectomy, tonsillectomy, removal of an esophageal foreign body, microlaryngoscopy with papilloma excision, endoscopic sinus surgery, septorhinoplasty, and thyroidectomy. Six patients required reintubation. Treatment included positive pressure ventilation, oxygen therapy, and diuretics. Seven patients were discharged within 24 hours and the others were discharged between 2 and 8 days postoperatively. There were no mortalities. Conclusion: Laryngospasm resulting in PPE may occur in both children and adults after various otolaryngologic procedures. Among the subgroup of children, our study is the first to report its occurrence in healthy children without sleep apnea undergoing elective surgery. [source]


Overnight Hospital Stay Is Not Always Necessary after Uvulopalatopharyngoplasty,

THE LARYNGOSCOPE, Issue 1 2005
FACS, Jeffrey H. Spiegel MD
Abstract Objectives: To determine whether patients with obstructive sleep apnea who undergo uvulopalatopharyngoplasty (UPPP) have a significant incidence of postoperative complications that would justify overnight postoperative observation in the hospital. Study Design: Part 1: review of published medical literature to determine incidence of postoperative complications. Part 2: retrospective review of 117 patients undergoing UPPP with or without additional procedures. Methods: A literature search for existing studies describing the postoperative complications after UPPP for obstructive sleep apnea was conducted. After this, the records of 117 patients who had undergone UPPP at a university-based medical center during a 5-year span were reviewed. Results: Respiratory events occur in 2% to 11% of cases. These include airway obstruction (e.g., laryngospasm), postobstructive pulmonary edema (POPE), and desaturation. Airway obstruction occurred in the immediate postoperative setting. POPE was rare and usually occurred within minutes after the conclusion of the surgical procedure. Desaturation could occur at any time, but the severity was usually equivalent to that found on preoperative sleep study. Hemorrhage occurred in 2% to 14% of cases and had a biphasic incidence, occurring either immediately postoperatively or several days after surgery. Depending on definition, hypertension was observed in between 2% and 70% of patients postoperatively. This was most commonly diagnosed and treated in the immediate postoperative setting. In most reports, arrhythmia and angina occurred in less than 1% of cases. Conclusions: The majority of complications after UPPP with or without additional procedures occur within 1 to 2 hours after surgery. Postoperative oxygen desaturation is usually no worse than that that was observed on preoperative polysomnography findings. A 2 to 3 hour observation period may be suitable for patients after UPPP; if a patient experiences no complications and is maintaining adequate oxygenation and analgesia, same-day discharge from recovery room may be considered.

Early Hemodynamic Injury During Donor Brain Death Determines the Severity of Primary Graft Dysfunction after Lung Transplantation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 1 2007
V. S. Avlonitis
Sympathetic discharge and hypertensive crisis often accompany brain death, causing neurogenic pulmonary edema. Progressive systemic inflammatory response develops, which can injure the lung further. We investigated whether (a) early hemodynamic injury during donor brain death increases reperfusion injury after lung transplantation and (b) delaying lung recovery would augment reperfusion injury further, because of the progressive systemic inflammatory response in the donor. Brain death was induced by intracranial balloon inflation in rats, with or without ,-adrenergic blockade pretreatment to prevent the hypertensive crisis. Another group of rats had a sham procedure. Lungs were retrieved 15 min after brain death or sham procedure and reperfused using recipient rats. In a fourth group, brain death was induced and the lungs were retrieved 5 h after brain death and reperfused. Postreperfusion, lungs retrieved early from untreated brain-dead donors developed more severe reperfusion injury, as assessed by functional parameters and inflammatory markers, than those from sham or alpha-blockade-treated donors. Lungs retrieved late from brain-dead donors had similar inflammatory markers after reperfusion to those retrieved early, but significantly lower pulmonary vascular resistance. Early hemodynamic damage during donor brain death increases reperfusion injury after lung transplantation. Delaying retrieval may allow the lung to recover from the hemodynamic injury. [source]
